Ikhwalithi ephezulu Yezimboni ze-NBR isheke ivalvu yebhola Umkhiqizi wefektri wase-China
Yini i-valve yokuhlola ibhola ye-NBR?
AI-valve yokuhlola ibhola ye-NBRiyi-valve elula nethembekile enebhola eliyindilinga njengengxenye eyodwa kuphela ehambayo yokuvimba ukugeleza okubuyela emuva.Ngenxa yokugeleza kwayo okulula nokungalungiseki kahle i-valve ivamise ukucaciswa futhi isetshenziswe eziteshini zokuphakamisa amanzi angcolile angaphansi kwamanzi.Isihlalo sevalvu esinembobo egcwele siklanywe ngendlela eyingqayizivele evumela ibhola ukuthi lihlale lingavuzi ngaphandle kokungena i-wedge esihlalweni sevalvu.Ekufakweni kwevalvu yevacuum noma yokunqanda izikhukhula, kusetshenziswa ibhola "elintantayo" kune "lizikayo".
I-valve yokuhlola ibhola ye-NBRaqukethe 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 liyehla liye phezulu ngaphakathi kwevalvu kuye ngokugeleza futhi livale 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 ze-valve yokuhlola ibhola le-NBR
Izici kanye nezinzuzoI-valve yokuhlola ibhola ye-NBR
- *Isihlalo se-valve esinembobo egcwele siklanywe ngendlela ehlukile evumela ibhola ukuthi likwazi ukuhlala lingavuzi ngaphandle kokungena ku-valve.
- *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 yokuhlola ibhola le-NBR
Izicelo zevalvu yokuhlola ibhola le-NBR
Lolu hloboI-valve yokuhlola ibhola ye-NBRisetshenziswa 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.I-t'a iphinde isetshenziswe kakhulu eziteshini zokumpompa okungavamisile ukuhanjelwa kuzo, njengoba zifuna ukulungiswa okulinganiselwe kuphela, ngokuvamile uma ibhola lenza umsindo obangelwa umthamo wepompo onganele noma isando samanzi.
