I-valve yokuhlola ibhola ye-valve engabuyisi yezimboni esezingeni eliphezulu Umkhiqizi waseChina Umhlinzeki wefektri
Iyini ivalvu engabuyisi?
AIvalvu engabuyisiiyivalvu elula nethembekile enebhola eliyindilinga njengengxenye ehambayo kuphela yokuvimba ukugeleza okuphambene. Ngenxa yomklamo wayo olula wokugeleza ophumelelayo futhi ongenakho ukulungiswa, ivalvu ivame ukucaciswa futhi isetshenziswe eziteshini zokuphakamisa amanzi amdaka ezicwiliswa emanzini.
Ivalvu engabuyisiiqukethe ibhola elihlala esihlalweni, elinembobo eyodwa kuphela. Isebenza ngebhola elihamba phezulu naphansi ngaphakathi kwevalvu. Isihlalo senziwe ngomshini ukuze silingane nebhola, futhi igumbi libunjwe ngendlela eqondile ukuze liqondise ibhola esihlalweni ukuze livale futhi limise ukugeleza okuphambene. Ibhola linobubanzi obukhulu kancane kunobomgodi odlulayo (isihlalo). Lapho ingcindezi engemuva kwesihlalo idlula lokho okungaphezu kwebhola, uketshezi luvunyelwe ukugeleza ngevalvu. Kodwa uma ingcindezi engenhla kwebhola idlula ingcindezi engaphansi kwesihlalo, ibhola libuyela esihlalweni, lenze uphawu oluvimbela ukugeleza okungemuva. Ibhola lihamba phezulu naphansi ngaphakathi kwevalvu kuye ngokugeleza futhi livale esihlalweni esinomshini lapho kungekho ukugeleza noma ukugeleza okuphambene okwenzekayo futhi livale ngokumelene nesihlalo ukuze limise ukugeleza okuphambene. Amavalvu okuhlola anebhola eline-Buna-N njengejwayelekile futhi anamabhola e-phenolic amelana nokugqwala ukuze asetshenziswe.
Izici eziyinhloko ze-valve engabuyisi
Izici kanye nezinzuzo zeIvalvu engabuyisi
- *i-valve yokuhlola ibhola iyi-ivalvu elula nethembekile enebhola eliyindilinga njengengxenye ehambayo kuphela yokuvimba ukugeleza okuphambene,umklamo ongenakho ukulungiswa, i-suitbale yeziteshi zokuphakamisa amanzi amdaka ezicwiliswa emanzini.
- *NortechI-Ball Check Valveziyazihlanza, njengoba ibhola lijikeleza ngesikhathi sokusebenza okususa ingozi yokuthi ukungcola kubhajwe ebholeni.
- *Imbobo egcwele nebushelelezi iqinisekisa ukugeleza okugcwele ngokulahlekelwa umfutho ophansi futhi isusa ingozi yokufakwa phansi okungavimbela ukuvalwa okuqinile. Ibhola elijwayelekile lenzelwe insimbi eboshwe ngerabha ye-NBR, futhi ubulukhuni berabha bulungiselelwe ukuvimbela ibhola ukuthi lingabhajwa esihlalweni. Amabhola e-polyurethane afanelekela imidiya yokuhluza futhi lapho kudingeka amabhola ahlukene isisindo ukuvimbela umsindo kanye nesando samanzi.

Umbukiso Womkhiqizo: I-valve engabuyisi
Ukusetshenziswa kwevalvu engabuyisi
Lolu hlobo lweIvalvu engabuyisiisetshenziswa kabanzi ekusetshenzisweni kwamanzi angcolile, ezitshalweni zikagesi kanye nasembonini yezinqubo. Ivalvu yokuhlola ibhola ifanele ukusetshenziswa ezindaweni ezingcolile (kufika ku-120˚F) njengoba ivalvu emise okwebhola ivimbela ukuqoqana kokungcola. Ngokuvamile isiteshi sokuphakamisa amanzi angcolile sizoba nevalvu yokuhlola ibhola ukuvimbela ukugeleza okuphambene. Isetshenziswa kabanzi nasezikhungweni zokupompa ezingatholakali njalo, njengoba zidinga ukulungiswa okulinganiselwe kuphela,
