I-Rotta 3-lug coupling iyisixhumi esikhethekile esixhuma ngokushesha esenzelwe ikakhulukazi ukudluliswa koketshezi olunesivinini esikhulu ezinhlelweni zokuvikela umlilo kanye nezamabhampu ezimbonini. Lolu hlobo lwe-coupling, olwaziwa nangokuthi i-GOST coupling ngenxa yemvelaphi yalo ezindinganisweni zaseRussia nase-Eastern Europe, lunezikhala ezintathu ezihlukaniswe ngokulinganayo ezikhiya emigqeni ehambisanayo ku-adapter ehlangene ngokunyakaza okulula kwekota. Ngokungafani noxhumano oluboshiwe noma oluboshiwe, umklamo we-Rotta ususa isidingo samathuluzi, uvumela abacimi bomlilo nabasebenzi bamabhampu ukuthi baxhume noma bahlukanise ukuxhumana ngemizuzwana ezimeni ezinzima. Lo mshini usekelwa izikhala ezicwengwe ngokunemba kanye ne-gasket yokuvala eqinile eqinisa ngokulinganayo lapho i-coupling isihlangene ngokugcwele. Ekuqaleni yenzelwe ukuhlangabezana nezimfuneko eziqinile zezimboni zesikhathi seSoviet, i-Rotta 3-lug coupling selokhu yathola ukwamukelwa kabanzi ezimakethe zomhlaba wonke ngenxa yokwethembeka kwayo nokusebenziseka kalula. Namuhla, iyisici esijwayelekile ezinhlelweni zikamasipala zomlilo, imigqa yokungena nokukhipha yamabhampu aphathwayo, nemishini yokuphendula ezimo eziphuthumayo emhlabeni wonke. Ukuqonda ifilosofi yayo yomklamo kusiza ukuchaza ukuthi kungani le coupling ihlala iyikhetho oluncamelayo phezu kwezinye izindlela ezifana ne-camlock noma i-Storz fittings ezindaweni eziningi ezinobungozi obukhulu. I-coupling ngokuvamile yenziwa ngezinto ezilula kodwa eziqinile njenge-aluminum alloy, ne-brass noma i-stainless steel variants etholakalayo ezindaweni ezonakalisa noma ezishisa kakhulu. Lesi sivunguvungu sokwethulwa sibeka isiteji sokuhlola okujulile kwezici, izicelo, nezinzuzo ezenza i-Rotta 3-lug coupling ibe yinto ebalulekile ekuxhumaneni komlilo namabhampu.

I-Rotta 3-lug coupling yakhelwe ngezici ezintathu eziyinhloko zokusebenza: isivinini sokuxhuma esisheshayo, ukuqina okungavamile komshini, kanye nokubeka uphawu oluqinisekile oluvimbela ukuvuza. Umsebenzi wokuxhuma osheshayo uvela kumklamo wokukhiya we-lug ezintathu, ovumela umsebenzisi ukuthi alinganise ama-lug nezikhala ze-adapter bese ejikela i-coupling cishe ngo-90 degrees kuze kube yilapho kuzwakala ukumiswa okuqinisekile. Lesi senzo se-quarter-turn asidingi amaswidi, izando, noma amathuluzi akhethekile, kunciphisa isikhathi sokulungisa kakhulu phakathi nemisebenzi ebalulekile yokucisha umlilo noma yokulungiselela amaphampu. Umzimba we-coupling uvame ukubunjwa noma ukwenziwa kusuka ku-aluminum alloy eqinile, bese uboshwa kanzima noma upende nge-powder ukuze umelane nokuklwejwa, ukugqwala, kanye nomonakalo wokushayeka ezindaweni zokusebenza. Uhlelo lokubeka uphawu lugxile ku-gasket ye-elastomeric engashintshwa — evame ukwenziwa nge-EPDM noma irabha ye-NBR — ehlala endaweni eqoshiwe futhi icindezela ngokulinganayo lapho ama-lug ebandakanyeka, idala umgoqo oqinile wokuvimbela ukuvuza kwamanzi ngisho nasezingcindezi ezingaphezu kuka-16 bar. Izivivinyo zasensimini zibonise ukuthi i-Rotta coupling egcinwe kahle ingamelana nezinkulungwane zezikhathi zokuxhuma ngaphandle kokuphuma okulinganisekayo noma ukuguga kobukhulu. Ama-lug ngokwawo akhelwe ngama-radii amakhulu kanye nendawo engaphezulu ukusabalalisa amandla okucindezela ngokulinganayo, kuvimbela ukucindezeleka okungaholela ekugqekezweni noma ekuguqukeni ngaphansi kokwanda okungazelelwe kwezingcindezi. Ngaphezu kwalokho, i-coupling ihlanganisa inkomba yokulinganisa ebonakalayo, njengomugqa opendiwe noma uphawu olubunjiwe, oluqinisekisa ukubandakanyeka okugcwele ngokubheka nje. Le nhlanganisela yesivinini, amandla, kanye nokuqiniseka kokubeka uphawu kwenza i-Rotta 3-lug coupling ifanelekele kakhulu ukuxhunywa kwe-fire hydrant lapho yonke imizuzwana ibalulekile futhi lapho ingcindezi yesistimu ingashintshashintsha kakhulu phakathi nokusebenza. Ngaphezu kwalokho, ukwakhiwa okulula kwe-coupling kwenza kube lula ukuhlola ensimini nokushintsha i-gasket ngaphandle kokuqeqeshwa okukhethekile, kwandisa impilo yesevisi yomhlangano wonke.

I-Rotta 3-lug coupling isiyona esiyisixhumanisi esiyinhloko phakathi kwezinsimbi zomlilo namapayipi omlilo, kanye naphakathi kwamaphampu nemigqa yokudonsa noma yokukhipha kokufakwa okuhambayo nokumile. Ezinhlelweni zomlilo zomlilo zikamasipala, i-coupling ivamise ukufakwa kuphuma ku-hydrant, ivumela abacimi bomlilo ukuthi baxhume amapayipi noma amaphampu aphathwayo ngokushesha lapho befika endaweni. Isenzo sokukhiya se-quarter-turn sibaluleke kakhulu lapho kusebenza ezimeni zokubona okungabikhona — njengezindawo ezigcwele intuthu noma izimo eziphuthumayo ebusuku — ngoba impendulo yokuthinta kanye nokuchofoza okuzwakalayo kuqinisekisa ukuxhumana okuphephile ngaphandle kokudinga ukuqinisekiswa ngokubonwa. Ezixhumanisweni zamaphampu, i-Rotta coupling isetshenziswa ohlangothini lokungena ukuxhuma amapayipi okudonsa kumaphampu omlilo aphathwayo, futhi ohlangothini lokukhipha ukuxhuma amapayipi okudiliva ngqo kuphuma kuphampu noma ezinhlelweni zokusabalalisa izimbazo. Ezindaweni zezimboni, la ma-coupling atholakala ezinhlelweni zamanzi okupholisa, imisebenzi yokukhipha amanzi, nemigqa yokudlulisa amakhemikhali lapho ukunqamuka okusheshayo ukuze kulungiswe noma kulungiswe kabusha kubalulekile. I-coupling iphinde yamukelwe kabanzi ezinhlelweni zokunisela ezolimo ezidinga ukuhanjiswa kabusha kwamapayipi njalo, nasezindaweni zezimayini lapho kudingeka khona ukuxhumana okuqinile, okumelana nodoti. Ngoba umklamo we-Rotta udala imbobo yangaphakathi ebushelelezi ngaphandle kwezithiyo eziphuma ngaphandle, inciphisa ukugeleza nokudideka, okubalulekile ekugcineni ukusebenza kahle kwephampu nokunciphisa ingozi yokuvuvukala. Izimoto zokuphendula eziphuthumayo ezifana namaloli omlilo, izindiza zokucisha umlilo ezindizeni, kanye namayunithi okusiza ezimbonini avame ukuphatha izihambisi eziguqula ama-Rotta coupling kwezinye izindinganiso, ziqinisekisa ukusebenzisana nezinhlelo zamanzi ezikhona. Ukusebenza okuhlukahlukene kwe-Rotta 3-lug coupling kudlulela kokufakwa okungaphezulu komhlaba nokungaphansi komhlaba, njengoba izinto ezisetshenzisiwe zingamelana nokugqwala komhlabathi nokulayisha komshini lapho kufakwa emakamelweni amavalvu noma amabhokisi amamitha. Kuso sonke isicelo, ikhono le-coupling lokubhekana nezinga eliphezulu lokugeleza ngenkathi ligcina ukuxhumana okuphephile, okungavuzi, kwenza kube yingxenye ethembekile ezinhlelweni zokuphepha komlilo nokudlulisa uketshezi emhlabeni wonke.

Uma kuqhathaniswa nezinye izinhlobo zokuxhuma ezifana ne-camlock, i-Storz, izintambo, noma izixhumi eziboshiwe, i-Rotta 3-lug coupling inikeza ibhalansi eyingqayizivele yesivinini, ubulula, kanye nekhono lokuphatha ingcindezi elihambisana kahle nezidingo zezicelo ze-fire hydrant nezamajampu. Izixhumi ze-Camlock, nakuba zisheshe ukuxhuma, zincike kumalungu e-cam angakwazi ukukhishwa ngephutha ngokudonswa noma ukushaywa kwelayisi, kanti amalugu okukhiya aqinile e-Rotta ayamelana nokungaxhunywa ngephutha. Izixhumi ze-Storz, ezisebenzisa umklamo we-lug ezimbili ezifanayo, zidinga ukulungiswa okuyiqiniso kwe-axial futhi zingaba nzima ukuxhuma lapho amalayi engaphansi kwengcindezi noma lapho umsebenzisi egqoke amagilavu ​​aqinile; i-Rotta's three-lug geometry ihlinzeka ngokulungiswa okulula nokubekezelelana okuxolelayo kokuqala. Izixhumi ezintambo, nakuba ziqinile kakhulu, zidinga isikhathi esiningi ukuzigoqa nokuzikhipha, futhi zivame ukuba nezinkinga zokuxhuma okungalungile nokuguguleka, ikakhulukazi ezindaweni ezingcolile noma ezonakalisa – izinkinga i-Rotta coupling eziqeda ngokuphelele. Izixhumi eziboshiwe zinikeza izilinganiso eziphakeme kakhulu, kodwa zidinga amathuluzi, izibopho eziningi, nesikhathi esiningi somsebenzi, okwenza zingasebenzi ezimweni zokuphendula eziphuthumayo lapho isivinini sibaluleke kakhulu. I-Rotta coupling iphinde ibe yinhle ezimweni lapho amalayi noma amapayipi kufanele axhunywe futhi axhunywe kabusha njalo, njengoba izindawo zayo zokuguga zakhelwe ukujikeleza okuphindaphindayo ngaphandle kokulahlekelwa ukusebenza kokubopha. Enye inzuzo ebalulekile ubude be-axial obuncane bokuxhuma, obunciphisa isikhala esidingekayo kumagumbi okugcina futhi buvumela ukuhlelwa kwamalayi acindezelwe kakhulu kumaphaneli ejampu. Ngokombono wezindleko, izixhumi ze-Rotta ngokuvamile zishibhile kunezinye izindlela eziphakeme ze-Storz noma eziboshiwe, kuyilapho zinikeza izilinganiso zengcindezi ezifanayo noma ezingcono kakhulu ezicelo ezijwayelekile zomlilo kuze kufike ku-20 bar. Ubulula bomklamo futhi kusho izingxenye ezimbalwa ezingahluleka – azikho izintambo, ama-cam levers, noma izigubhu eziningi okufanele zigcinwe – okuhumusha ezindlekweni zokusebenza ezincane kanye nokwethembeka okukhulu emkhakheni. Ngalezi zizathu, iminyango eminingi yomlilo kanye nabasebenzi bamajampu ezimboni baye bajwayela izixhumi ze-Rotta 3-lug njendlela yabo yokuxhuma ekhethiwe kuzo zombili izicelo ze-hydrant nezamajampu.

I-Rotta 3-lug coupling yenziwa ngokuhambisana ne-GOST 28352-89 namazinga kazwelonke aseRussia ahlobene, achaza imininingwane yobukhulu, izilinganiso zengcindezi, izidingo zezinto, nezinqubo zokuhlola lezi zixhumi. Ngaphandle kokuqala kwayo kumazinga e-GOST, i-coupling yamukelwe emhlabeni wonke futhi ivame ukubhekiselwa kumihlahlandlela ye-ISO, EN, noma i-NFPA yoxhumi bamaloli omlilo ezindaweni eziningi. Ukulinganisa kobukhulu kuqinisekisa ukuthi ama-Rotta couplings avela kubakhiqizi abahlukene angashintshana, okuvumela iminyango yomlilo nabasebenzisi bezimboni ukuthi bathole izingxenye kubahlinzeki abaningi ngaphandle kwezinkinga zokuhambisana. Ubukhulu obujwayelekile buqala ku-DN25 (1 inch) kuya ku-DN150 (6 inches), nge-DN80 (3 inch) kanye ne-DN100 (4 inch) okuyizona ezivame kakhulu kuxhumi bamaloli omlilo namaphampu ezinhlelweni zikamasipala nezimboni. Ingcindezi evamile yokusebenza yamaloli e-Rotta e-aluminum ngokuvamile ingu-16 bar, nezinguqulo ezinengcindezi ephezulu ezilinganiselwe ku-25 bar ezitholakala ku-aluminum eyenziwe nge-forged noma insimbi engagqwali yezicelo ezidingayo. Ukuhambisana nezinye izinhlobo zama-coupling kufezekiswa ngokusebenzisa ama-adapter — isibonelo, i-Rotta-to-Storz adapter ivumela iloli lomlilo elihlomele izindawo ze-Storz ukuthi luxhume ku-hydrant enama-Rotta, noma okuphambene nalokho. Abakhiqizi abaningi, okubandakanya iVaricpand International, banikeza imigqa yemikhiqizo ebanzi ehlanganisaIzingxenye ze-Gost & Rottakanye nezesekeli ezihambisanayo njengama-dust caps, ama-gaskets, namavalvu okukhulula ingcindezi. Kubalulekile ukuthi ochwepheshe bokuthenga baqinisekise ukuthi impahla yokuxhuma ihambisana nemvelo yenkonzo ehlosekayo: i-aluminium yokucisha umlilo ejwayelekile, ithusi lokuchayeka olwandle noma amakhemikhali abola kalula, kanye ne-stainless steel yokushisa okuphezulu noma imidiya enolaka. Lapho ubuyekeza izinhlelo ezikhona, abasebenzisi kufanele balinganise ububanzi begroove nokuhlukaniswa kwe-lug ukuze baqinisekise ukuhambisana nezinga le-GOST, njengoba ukuhluka okuncane kungadala ukuvuza noma ubunzima ekuxhumaneni. Izitifiketi ezivela eceleni njengokumakwa kwe-CE noma ukufakwa kuhlu kwe-UL kungasebenza nasezixhumanisweni ze-Rotta ezisetshenziswa ezinhlelweni zokuvikela umlilo, kuye ngezimfuneko zomthetho zendawo. Ngokunamathela ezingeni elibonwayo, isixhumanisi se-Rotta 3-lug siqinisekisa izinga lokushintshana nokubikezela ukusebenza okubalulekile ekuphepheni komsebenzi obalulekile kanye nemisebenzi yokumpompa.

Ukufakwa kahle nokugcinwa njalo kubalulekile ukuze kukhuliswe impilo yesevisi nokusebenza okungenavuza kwezixhumi ze-Rotta 3-lug ekuxhumaneni komlilo nezixhumi zamaphampu. Ngesikhathi sokufakwa, qinisekisa ukuthi kokubili isixhumi nesihambelani esihlangene sihlanzekile, sikhululekile othulini, itshe eliqinile, noma izingcezu ezindala zokubopha, nokuthi ibhodi lihlezi kahle endaweni yalo ngaphandle kokuhlanekezela noma ukujika. Isixhumi kufanele sicindezelwe ngokugcwele kusihambelani kuze kube yilapho izikhonkwane zithinta izikhawu eziphakanyisiwe, bese sijikelezwa ngendlela yewashi (ngokuvamile) kuze kube yilapho kuzwakala isikhawu esiqinile futhi izimpawu zokuhambisana zihambisana — ungaze uphoqelele isixhumi ngaphezu kwesikhawu somshini, njengoba lokhu kungalimaza izikhonkwane noma kuphambanise indlu. Ukuze kufakwe unomphela noma okungapheli, njengokukhipha umlilo, kuyinto enhle ukufaka ungqimba oluncane lwe-silicone grease ebhodini nasemikhawulweni ukuze kube lula ukukhipha esikhathini esizayo nokunciphisa ukuguga. Ukuhlola njalo kufanele kufake ukuhlola okubonakalayo kwezimbotshana, ukugqwala, ukuhlanekezela kwezikhonkwane, noma ukubola kwebhodi, ngokugxila ikakhulukazi endaweni yokubopha lapho ibhodi licindezela khona ubuso besihambelani. Amabhodi kufanele ashintshwe okungenani njalo ngonyaka ekusebenzeni okusebenzayo, noma ngokushesha uma kutholakala noma yiziphi izimpawu zokusika, ukucindezela okuhlala njalo, noma ukuqina. Noma yiziphi izimpawu zokuqhaqhazela ngesikhathi sokusebenza zidinga ukuvalwa okusheshayo nokuhlola, njengoba ukudonsa okuncane kungakhula ngokushesha ngaphansi kwezimo zokugeleza okunomfutho ophakeme. Ukugcinwa kwezixhumi ezisele nezihambelani kufanele kube endaweni ehlanzekile, eyomile kude nelangeni eliqondile, imithombo ye-ozone, namakhemikhali angalimaza izingxenye ze-elastomeric. Ukuze uthole izixhumi zamaphampu, kuyasiza ukufaka i-pressure gauge ngaphansi kwesixhumi ukuze ubheke ukwehla komfutho okungabonisa ukuthi isixhumi asihlangene ngokugcwele noma siqhaqhazela. Ukuqeqeshwa kwabasebenzi kufanele kugcizelele ukubaluleka kokuqinisekisa ukuhlangana okuphelele kusetshenziswa izinkomba zokuthinta nezokubona, kanye nenqubo efanele yokukhipha ngaphansi komfutho osele — ngokuvamile ngokuvula kancane i-bleeder valve noma ukukhulula umfutho wephampu ngaphambi kokujikeleza isixhumi. Ngokulandela lezi zindlela ezingcono kakhulu, abasebenzisi bangaqinisekisa ukuthi izixhumi zabo ze-Rotta 3-lug zinikeza ukusebenza okuzinzile, okuthembekile eminyakeni eminingi yesevisi ekuxhumaneni komlilo nezixhumi zamaphampu.
