I-Back Pressure Valve
Ukusebenza Okuphezulu Kwe-Stainless Steel Relief Pressure Safety Valve for Dosing Pump
Iluphi uhlobo lwe-valve ye-valve yokucindezela emuva?
Ivalvu yokucindezela emuva (Ivaluvu Yokucindezela Emuva) uhlobo lwevalvu esetshenziselwa ukulawula ukucindezela koketshezi, okuvumela uketshezi ukuthi lugcine ukucindezela okuthile epayipini. Amavalvu okucindezela emuva ngokuvamile afakwa ekupheleni kwepayipi ukuvimbela ukugeleza emuva noma ukugeleza koketshezi epayipini nokulawula izinga lokugeleza nokucindezela koketshezi. Isimiso sokusebenza se-valve yokucindezela emuva ukulawula ukucindezela kwamanzi ngokulungisa ukuvulwa kwe-valve. Uma ukucindezela epayipini kudlula inani elibekiwe, ivalvu ivala ngokuzenzakalelayo ukuvimbela uketshezi ukuthi lungagelezi luhlehle noma luhlehle. Ama-valve okucindezela emuva asetshenziswa kabanzi embonini yamakhemikhali, i-petroleum, igesi yemvelo, ukwelashwa kwamanzi kanye neminye imikhakha.
Isebenza kanjani i-back pressure?
I-valve yokucindezela emuva isetshenziselwa ukulawula isiqondiso sokugeleza kwamanzi nokucindezela. Isebenza ngokusebenzisa isiphethu noma ipiston ngaphakathi kwevalvu ukuze uketshezi lukwazi ukugeleza luye ohlangothini olulodwa kuyilapho luvimbela ukugeleza okubuyela emuva. Lapho uketshezi lugeleza luye phambili, i-valve iyavuleka futhi uketshezi lungadlula ngokukhululeka. Lapho uketshezi lugeleza lubheke emuva, i-valve iyavala futhi ivimbele uketshezi ukuthi lungadluli. Okufeza inhloso yokulawula isiqondiso sokugeleza koketshezi nokucindezela. Ekukhiqizeni izimboni, i-valve yokucindezela emuva ivame ukusetshenziselwa ukulawula ukugeleza nokucindezela ohlelweni lwamapayipi ukuqinisekisa ukusebenza okuvamile kwesistimu.
Uyini umsebenzi we-back pressure?
Umsebenzi wawo ukugcina ingcindezi ethile emuva noma ukuvimbela ukugeleza emuva ohlelweni lwamapayipi. Enqubweni yokugeleza koketshezi noma kwegesi, uma ingcindezi epayipini iphansi kunevelu ethile, izoholela ekugelezeni okubuyela emuva koketshezi noma igesi, le nto ibizwa ngokuthi ukugeleza okubuyela emuva. I-valve yokucindezela emuva ingashintshwa ngokulungisa ukuvulwa kwe-valve. Ukuze ingcindezi ephayiphini igcinwe ngaphakathi kwebanga elithile, ngaleyo ndlela kuvinjwe ukuvela kwesenzakalo sokugeleza emuva.
Ingabe i-valve ye-throttle ingasetshenziswa njenge-valve yokucindezela emuva?
Ama-valve e-throttle angasetshenziswa njengama-valve okucindezela emuva. Kodwa ukusebenza kwawo nokusebenza kwawo kungase kungabi kuhle njenge-valve yokucindezela emuva eklanywe ngokukhethekile. I-valve yokucindezela emuva iwukuba ukulawula ingcindezi ohlelweni lwamapayipi ukuvimbela ukucindezela okukhulu ekulimazeni uhlelo. Ama-throttle valves, ngakolunye uhlangothi, asetshenziselwa kakhulu ukulawula ukugeleza nokucindezela. kanye nesakhiwo sabo kanye nesimiso sokusebenza kuhlukile kulawo ama-valve okucindezela emuva. Ngakho-ke, uma udinga ukulawula ngokuqinile ingcindezi yangemuva ohlelweni lwamapayipi, kunconywa ukukhetha i-valve yokucindezela emuva eyakhelwe ngokukhethekile.
