Ivalvu yesheke Yekhwalithi Yezimboni yase-China Umkhiqizi wefekthri wase-China
Iyini i-valve yokuhlola?
I-valve yokuhlola iwuhlobo lwe-valve yenjongo eyodwa-directional, futhi njengama-valve angabuyi.
Hlola Valveiyi-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".
hlola ama-valveaqukethe 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.
Izici eziyinhloko ze-valve yokuhlola
Izici kanye nezinzuzoHlola Valve
- vimba ukugeleza okubuyela emuva,umklamo ongenakulungiswa, i-suitbale yeziteshi zokuphakamisa amanzi angcolile angaphansi kwamanzi.
- *Isihlalo se-valve esinembobo egcwele siklanywe ngendlela ehlukile evumela ibhola ukuthi likwazi ukuhlala lingavuzi ngaphandle kokungena ku-valve.
- *I-NortechHlola 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.

Izicelo ze-valve yokuhlola
Lolu hlobohlola i-valveisetshenziswa 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 kabanzi eziteshini zokupompa ezingavami ukuhanjelwa abantu
