I-Back Pressure Valve
I-UPVC CPVC PPH PVDF Back Pressure Valve Pvc Relief Pressure Safety Valve
Izici Zemikhiqizo
Khipha umfutho wepayipi ukuze uqinisekise ukuzinza kwengcindezi yesistimu.
Vikela ukuphepha kwepompo kanye nokusebenza okuvamile kwesistimu.
Kusetshenziswa ngokuhambisana nama-pulse dampers ukunciphisa ukulimala kwesando samanzi ohlelweni, ukufeza ukulawulwa kokudlidliza okuphansi okuphezulu; ukunciphisa inani eliphakeme lokuguquguquka kwezinga lokugeleza, ukuvikela uhlelo lwamapayipi kumthelela wokuguquguquka kwengcindezi.
I-diaphragm isebenzisa ubuchwepheshe obuthuthukisiwe be-PTFE+glue, obufanele cishe lonke uketshezi olubolayo, oluvalekayo okuthembekile futhi olungavuzi.
I-valve yokuphepha isetshenziselwa ini?
I-diaphragm, i-spool ngokucindezela kwentwasahlobo yangaphakathi ngokumelene nesihlalo se-valve. Lapho ingcindezi ephayiphini lesistimu idlula ingcindezi esethiwe, i-diaphragm, i-spool iyaboshwa. Ukuvuza okuphakathi kwepayipi lokubuya kanye nesiqukathi. Emkhakheni ingalungiswa ngezikulufu ngosizo lwegeyiji yokucindezela ephayiphini ebangeni elingu-0-1.0Mpa lezilungiselelo zengcindezi, ingcindezi yokusiza ngokuvamile ibekwe phezulu kunokucindezela kwesistimu okungu-0.1-0.2Mpa. Isilawuli se-valve yokuphepha asivunyelwe ukweqa umfutho wepompo omkhulu. Ukufaka ngokuvamile eduze ngangokunokwenzeka endaweni yepompo. Akufanele kube khona ama-valve phakathi kwepompo kanye ne-valve yokuphepha, ukuvikela ukuphepha kwepompo nokusebenza okuvamile kwesistimu.
Isetshenziselwa ini i-back pressure valve?
Ifakwe epayipini lokukhipha umfutho omuhle wephampu yemitha noma iphampu ye-diaphragm. Okuvimbela ukuvela kwe-siphon phenomenon, ukuqeda izinguquko zemithamo ezibangelwa ukushintshashintsha kwengcindezi endaweni yokulinganisa, ukuze kuqinisekiswe ukunemba komthamo wepompo. Ensimini sisusa i-cap yokuzivikela ezikulungeni zokulungisa, sijikeleze izikrini zokulungisa, futhi silungise ukucindezela okudingekayo ngosizo lwe-gauge yokucindezela epayipini. Ingalungiswa ngokulungisa izikulufu kububanzi obungu-0-0.6 Mpa ukuze usethe ingcindezi yangemuva. Okungasetshenziswa ngokuhambisana ne-pulse damper ukunciphisa umonakalo wesando samanzi ohlelweni. Ukugcina ukucindezela okuthile okungaguquki kusuka ku-outlet yepompo kuya ku-valve yokucindezela emuva, nokugcina izinga lokugeleza okuqhubekayo kwesistimu.
Uyini umehluko phakathi kwe-valve yokunciphisa ingcindezi kanye ne-back pressure valve?
I-valve yokucindezela emuva, iwuhlobo lwe-valve inhloso yalo eyinhloko ukuvikela ukusebenza okuphephile kwepompo. Ama-valve okucindezela emuva aqinisekisa ukusebenza okuphephile kwepompo ngokulawula ukusatshalaliswa kwengcindezi ye-inlet yepompo.
Ama-valve okunciphisa ukucindezela, noma ama-valve okulawula okuzenzakalelayo, asetshenziselwa ngokuyinhloko ukulawula ukucindezela kwesistimu. Ama-valve okunciphisa ingcindezi avame ukusetshenziswa kumapayipi kanye nezinhlelo ezidinga ukukwazi ukugcina ingcindezi ephansi njalo emishinini ethile lapho kunomkhawulo wokucindezela okuphezulu.
I-valve yokucindezela emuva isetshenziselwa ikakhulukazi ukuvikela ukusebenza okuphephile kwepompo, iyindlela "ezenzakalelayo" yokulawula i-valve. kuyilapho i-valve yokunciphisa ingcindezi isetshenziselwa ngokuyinhloko ukulawula ukucindezela kwesistimu, kunezindlela ezimbili "zemanuwali" kanye "ne-othomathikhi". Izindlela ezimbili. Ngaphezu kwalokho, i-valve evamile yokucindezela emuva isetshenziswa ekungeneni kwepompo, kuyilapho i-valve yokunciphisa ingcindezi isetshenziswa ekuphumeni kwesistimu, ikakhulukazi ngenxa yemisebenzi yabo eyinhloko ehlukene.
