Ama-valve okuvimbela ukugeleza kwe-backflowziyingxenye ebalulekile kunoma yiluphi uhlelo lwamanzi futhi zenzelwe ukuvimbela imiphumela eyingozi futhi engase ibe yingozi yokugeleza emuva. Njengengxenye ebalulekile yesistimu yokufaka amapayipi amanzi, la mavalvu enzelwe ukuvimbela amanzi angcolile ukuba asekele umthombo wamanzi ahlanzekile. Kunezinhlobo ezahlukene zamavalvu okuvimbela ukugeleza kokubuyela emuva emakethe, futhi kuyadingeka ukuqonda izici nezinzuzo zohlobo ngalunye, okuhlanganisa ama-valve okuvimbela ukugeleza kokubuyela emuva okukabili kanye namavalve uvemvane ahlala injoloba.
Enye yezinhlobo ezidume kakhulu zama-valve okuvimbela ukugeleza emuva yi-hlola kabili i-backflow preventer valve. Lolu hlobo lwe-valve luklanyelwe ukuhlinzeka ngokuvikelwa okwengeziwe kokubuyela emuva ngokuxhuma ama-valve okuhlola amabili ochungechungeni. Lawa ma-valve okuhlola aqinisekisa ukuthi amanzi ageleza ohlangothini olulodwa kuphela, okuvimbela noma yikuphi ukuguqulwa okungadingekile kokugeleza kwamanzi. Ama-valve okuvimbela ukugeleza kwe-back-sheck alungele ukusetshenziswa kwezentengiso nezimboni lapho ubungozi bokubuyela emuva buphezulu.
Olunye uhlobo lwe-valve yokuvimbela ukugeleza kwe-backflow i-valve ye-butterfly yesihlalo senjoloba, eyaziwa ngamakhono ayo okuvala ahle kakhulu. Lolu hlobo lwe-valve luklanywe ngesihlalo senjoloba esinikeza uphawu oluqinile futhi luvimbele ukungcola ukuthi kugeleze kubuyele emanzini ahlanzekile. Ama-valve ovemvane ahlezi enjoloba avame ukusetshenziswa ezindaweni zokuhlala nezincane zezentengiselwano lapho ukuvimbela ukubuyela emuva okuthembekile kubalulekile.
Uma kukhulunywa ngezici ze-valve yokuvimbela ukugeleza kwe-backflow, kunezici ezimbalwa ezibalulekile okufanele zicatshangelwe. Okokuqala, lawa ma-valve aklanyelwe ukuba athembeke futhi ahlale isikhathi eside, aqinisekise ukuthi ahlinzeka ngokuvikeleka okuqhubekayo kokubuyela emuva. I-valve ye-anti-backflow isebenzisa izinto ezihlala isikhathi eside nobunjiniyela obunembayo ukuze imelane nobunzima bokusetshenziswa kwansuku zonke ngaphandle kokuphazamisa ukusebenza.
Ukwengeza, ama-valve okuvimbela ukugeleza kwe-backflow aklanyelwe ukuba kube lula ukuwafaka nokugcina, ukunciphisa isikhathi sokuphumula nokuqinisekisa ukuthi uhlelo lwakho lwamanzi luvikelekile njalo. Ngenqubo yokufaka elula, eqondile kanye nezidingo zokugcinwa okuncane, lawa ma-valve ayisinqumo esihle kakhulu kunoma yiluphi uhlelo lwamanzi.
Ekuphetheni, i-backflow preventer valve iyingxenye ebalulekile kunoma yiluphi uhlelo lwamanzi futhi inikeza isivikelo esibalulekile engozini yokubuyela emuva. Kunezinhlobo ezihlukahlukene zamavalvu okuvimbela ukugeleza kokubuyela emuva atholakalayo, okuhlanganisa amavalvu okuvimbela ukugeleza kokubuyela emuva akabili kanye namavalve uvemvane ahlezi enjoloba, nokuqonda izici nezinzuzo zohlobo ngalunye kubalulekile ekukhetheni inketho elungele isicelo sakho esithile. Kungakhathaliseki ukuthi kusetshenziselwa ukuhlala, ukuhweba noma izimboni, ama-valve okuvimbela ukugeleza emuva ahlinzeka ngokuvikela okuthembekile, okuhlala isikhathi eside ohlelweni lwakho lwamanzi.
Ngaphandle kwalokho, i-TWS Valve, eyaziwa nangokuthi i-Tianjin Tanggu Water Seal Valve Co., Ltd, ithuthuke kakhulu kwezobuchwepheshe.i-valve ehlezi enjolobaamabhizinisi asekelayo, imikhiqizo i-elastic seat wafer butterfly valve, i-lug butterfly valve, i-valve ye-butterfly eyi-flange ephindwe kabili, i-valve e-eccentric butterfly valve,i-valve yebhalansi, i-wafer dual plate check valve, i-Y-Strainer nokunye. Uma unentshisekelo kulawa ma-valve, sicela ukhululeke ukusithinta. Ngibonga kakhulu!
