I-valve yokuhlola yezimboni esezingeni eliphezulu Umkhiqizi womhlinzeki wefektri waseChina
Iyini i-check valve?
I-valve yokuhlola uhlobo lwe-valve oluhloselwe ukuqondisa okukodwa, futhi njengama-valve angabuyisi.
Hlola i-Valveiyivalvu elula nethembekile enebhola eliyindilinga njengengxenye eyodwa ehambayo yokuvimba ukugeleza okuphambene. Ngenxa yomklamo wayo olula wokugeleza osebenza kahle futhi ongenakho ukulungiswa, ivalvu ivame ukucaciswa futhi isetshenziswe eziteshini zokuphakamisa amanzi amdaka angaphansi komhlaba. Isihlalo sevalvu esigcwele sakhiwe ngendlela ekhethekile evumela ibhola ukuthi lihlale liqinile ngaphandle kokungena esihlalweni sevalvu. Ekusetshenzisweni kwevalvu yokugeza noma yokulwa nokukhukhula, kusetshenziswa ibhola "elintantayo" esikhundleni "elicwilayo".
ama-valve okuhlolaiqukethe ibhola elihlezi esihlalweni, elinembobo eyodwa kuphela. Lisebenza 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 kunobomgobo ohambisanayo (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 liya phezulu naphansi ngaphakathi kwevalvu kuye ngokugeleza futhi livale ngokumelene nesihlalo esenziwe ngomshini lapho kungekho ukugeleza noma ukugeleza okuphambeneyo okwenzekayo futhi livale ngokumelene nesihlalo ukuze limise ukugeleza okuphambene.
Izici eziyinhloko ze-check valve
Izici kanye nezinzuzo zeHlola i-Valve
- vimba ukugeleza okuphambene,umklamo ongenakho ukulungiswa, i-suitbale yeziteshi zokuphakamisa amanzi amdaka ezicwiliswa emanzini.
- *Isihlalo sevalvu esigcwele siklanywe ngendlela ekhethekile esivumela ibhola ukuthi lihlale liqine ngaphandle kokungena evalvini.
- *NortechHlola i-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-check valve
Ukusetshenziswa kwe-check valve
Lolu hlobo lweivalvu yokuhlolaisetshenziswa 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 ukwakheka kokungcola. Ngokuvamile isiteshi sokuphakamisa amanzi angcolile sizoba nevalvu yokuhlola ibhola ukuvimbela ukugeleza okuphambene. Isetshenziswa kabanzi nasezikhungweni zokupompa ezingatholakali njalo.
