Ikhwalithi Ephakeme Yezimboni Ivalvu ye-valve yokuhlola ibhola Umkhiqizi wefektri wase-China
Yini i-valve engabuyi ?
AI-valve engabuyiiyi-valve elula nethembekile enebhola eliyindilinga njengengxenye eyodwa kuphela ehambayo yokuvimba ukugeleza okubuyela emuva.Ngenxa yokugeleza kwayo okulula nokuklama okunganakeki kahle i-valve ivame ukucaciswa futhi isetshenziswe eziteshini zokuphakamisa amanzi angcolile angaphansi kwamanzi.
I-valve engabuyiaqukethe ibhola elihlezi esihlalweni, elinembobo eyodwa kuphela.Isebenza ngebhola elihamba liye phezulu naphansi ngaphakathi kwevalvu.Isihlalo sifakwe ngomshini ukuze silingane nebhola, futhi igumbi limise ngendlela eqondile ukuze liqondise ibhola esihlalweni ukuze livaleke futhi limise ukugeleza okubuyela emuva. Ibhola linobubanzi obuthe ukukhudlwana kunolwembobo ephumela ngaphandle (isihlalo).Lapho ingcindezi engemuva kwesihlalo idlula leyo engaphezulu kwebhola, uketshezi luvunyelwe ukugeleza ku-valve.Kodwa lapho ukucindezela ngaphezu kwebhola kudlula ukucindezela ngaphansi kwesihlalo, ibhola libuyela ekuphumuleni esihlalweni, lenze uphawu oluvimbela ukugeleza emuva.Ibhola liya phezulu liye phansi ngaphakathi kwe-valve kuye ngokugeleza futhi livala ngokumelene nesihlalo somshini lapho kungekho ukugeleza noma ukugeleza okuhlehlayo okwenzekayo futhi livala ngokumelene nesihlalo ukumisa ukugeleza okubuyela emuva.amavalvu okuhlola anebhola elilayishiwe le-Buna-N njengejwayelekile futhi elinamabhola e-phenolic amelana nokugqwala wemidiya ehubhukayo.
Izici eziyinhloko zevalvu Engabuyi
Izici kanye nezinzuzo zeI-valve engabuyi
- *I-valve yokuhlola ibhola iyi-ai-valve elula nethembekile enebhola eliyindilinga okuwukuphela kwengxenye ehambayo yokuvimba ukugeleza okubuyela emuva,umklamo ongenakulungiswa, i-suitbale yeziteshi zokuphakamisa amanzi angcolile angaphansi kwamanzi.
- *I-NortechI-Ball Check Valveziyazihlanza, njengoba ibhola lizungeza ngesikhathi sokusebenza okususa ubungozi bokungcola okubhajwe ebholeni.
- *Ibhore eligcwele nelibushelelezi liqinisekisa ukugeleza okugcwele ngokulahleka kwengcindezi ephansi futhi lisusa ubungozi bokufakwa kwediphozithi phansi okungavimbela ukuvala okuqinile. Ibhola elijwayelekile liklanywe ngomgogodla wensimbi wenjoloba we-NBR, futhi ubulukhuni berabha buthuthukisiwe ukuvimbela ibhola ekubhajweni esihlalweni.Amabhola e-polyurethane afaneleka kumidiya e-abrasive futhi lapho amabhola ahlukene izisindo ezidingekayo ukuvimbela umsindo nesando samanzi.

Umbukiso Womkhiqizo: Ivalvu engabuyi
Izicelo zevalvu Engabuyi
Lolu hloboI-valve engabuyiisetshenziswa kabanzi ekusetshenzisweni kwamanzi angcolile, izitshalo zamandla kanye nomkhakha wezinqubo.Ivalvu yokuhlola ibhola ilungele ukusetshenziswa kumidiya engcolile (kufika ku-120˚F) njengoba ivalvu emise okwebhola ivimbela ukunqwabelana kokungcola.Ngokuvamile isiteshi sokuphakamisa amanzi angcolile sizoba ne-valve yokuhlola ibhola ukuvimbela ukugeleza okubuyela emuva.iphinde isetshenziswe kakhulu eziteshini zokupompa ezingavami ukuhanjelwa abantu, njengoba zifuna ukulungiswa okulinganiselwe kuphela,
