I-DIN ANSI UPVC CPVC PPH PVDF Wafer Check Valve Manufacture
Izici Zemikhiqizo
1) Ubude obufushane bobuso nobuso nokufaka kalula.
2)Ukumelana nokugqwala okuphezulu, Okungasindi futhi kuyabiza.
3) I-UPVC, ivalvu yesheke ye-CPVC ye-wafer evulekile ngokugcwele icishe ibe ngu-40°
I-4) Ngenxa yobubanzi obuncane bangaphakathi bama-flange e-PPH, ukuze uthole i-engeli enkulu yokuvula, kuyadingeka ukukhanda i-flange noma wengeze ipuleti lokuxhuma phakathi kwe-flange ne-valve.
Iyini inzuzo ye-wafer check valve?
I-valve yokuhlola i-wafer inobude besakhiwo se-valve emfushane, usayizi omncane nesisindo esilula. ukuvalwa kwe-valve okusheshayo, ukucindezela kwesando samanzi aphansi, indlela yokugeleza ebushelelezi, ukumelana noketshezi oluphansi. ipayipi elivundlile noma ipayipi eliqondile lingasetshenziswa. Kulula ukuyifaka, isenzo esibucayi, ukusebenza kahle kokuvala uphawu, ukushaywa kwe-valve emfushane, umthelela omncane we-valve, isakhiwo esilula, isimo esihle, impilo ende yesevisi, ukwethembeka okuphezulu. Ivimbela ukugeleza kwe-backflow okuphakathi / ukubuyela emuva, ukulawula okuzenzakalelayo kokuvula nokuvala nokunye.
I-valve yokuhlola i-wafer isetshenziswa kakhulu ku-petrochemical, iron and steel metallurgy, amandla kagesi kanye nezinye izimboni, zasemadolobheni kanye nezakhiwo eziphakeme zokuhlinzeka ngamanzi kanye nenethiwekhi yokudonsa amanzi. Ngoba ubude besakhiwo se-valve yokuhlola uxhumano lwe-clamp bufushane kune-valve yokuhlola uxhumano lwe-flange yendabuko. Yiyona efaneleka kakhulu ezindaweni ezinomkhawulo wesikhala sokufaka.
Yini okufanele inakwe lapho ufaka i-valve yokuhlola i-wafer?
1. Akuvunyelwe ukufaka i-valve ku-interface ye-pump flange, futhi kunconywa ukufaka i-valve okungenani izikhathi ezingu-10 ubude be-diameter ye-nominal (DN) 2 amamitha ngaphandle kwendawo yokuzinza.
2. Uma ufaka i-valve, kunconywa ukusebenzisa i-gasket flat ukuze unqume ukuvala uphawu.
3. Amapayipi anogqinsi olungaphezulu kwe-10 bar awavunyelwe. 4.
4. Ifanele ukufakwa okuvundlile noma mpo, ukufakwa okuqondile kuvumela kuphela uketshezi oluya phezulu.
5. Faka i-valve phakathi kwama-flanges (ukuqondanisa kwe-eksisi) futhi ufake i-torque enconywayo ukuze uqinise kokubili ama-flange.
