I-valve yokuhlola amanzi, eyaziwa nangokuthi i-check valve, i-check valve, i-counterflow valve, iyi-valve evula futhi ivale ngokuzenzakalelayo kuye ngokugeleza kwe-medium ngokwayo. Umsebenzi oyinhloko we-check valve ukuvimbela ukugeleza emuva kwe-medium, ukuvimbela ukuguqulwa kwephampu kanye ne-drive motor, kanye nokuphuma kwamanzi kwe-container media, nokuvikela ukuphepha kohlelo lwamapayipi kanye nemishini.

Amavalvu amancane okuhlolaingahlukaniswa kakhulu ngama-valve okuhlola okujikijelayo (ajikeleza ngokuya ngesikhungo sokudonsa amandla adonsela phansi) kanye nama-valve okuhlola okuphakamisa (ahamba nge-axis). Ama-valve okuhlola angasetshenziswa kumapayipi emidiya eyahlukahlukene kuye ngokuthi yini. Isici sokusebenza se-valve yokuhlola ukuthi umthwalo ushintsha kakhulu, imvamisa yokuvula nokuvala incane, futhi umjikelezo wokufaka uba mude kakhulu uma usufakwe esimweni sokuvala noma sokuvula, futhi izingxenye ezihambayo azidingeki ukuthi zinyakaze.

Njengoba i-valve yokuhlola ipuleti elikabili isetshenziselwa ukuvala ngokushesha ekusetshenzisweni okusebenzayo kakhulu, futhi lapho i-valve yokuhlola ivaliwe, i-medium igeleza iye ohlangothini, lapho i-valve ivaliwe, i-medium yehla ngokushesha isuka esivinini esiphezulu sokugeleza emuva iye ku-zero, futhi ingcindezi ikhuphuka ngokushesha, okungukuthi, isenzakalo "sesando samanzi" esingaba nomthelela omubi ohlelweni lwamapayipi. Ezinhlelweni zamapayipi anomfutho ophezulu anamaphampu amaningi ahambisanayo, inkinga yesando samanzi yama-valve okuhlola ivelele kakhulu.

Isando samanzi uhlobo lwegagasi lokucindezela ekugelezeni okudlulayo epayipini lokucindezela. Kuyisimo sokushaqeka kwe-hydraulic sokugxuma noma ukwehla kwengcindezi okubangelwa ukushintsha kwejubane loketshezi epayipini lokucindezela. Isizathu esibonakalayo siwumphumela wesenzo esihlangene sokungacindezeleki koketshezi, ukungabi namandla kokunyakaza koketshezi kanye nokunwebeka kwepayipi. Ukuze kuvinjelwe ingozi efihliwe yesando samanzi epayipini, eminyakeni edlule, onjiniyela basebenzise ezinye izakhiwo ezintsha nezinto ezintsha ekwakhiweni kwei-valve yokuhlola yensimbi engagqwaliukunciphisa umthelela wesando samanzi ngenkathi kuqinisekiswa ukusebenza okufanele kwevalvu yokuhlola.

I-Jinbin valve ineminyaka engu-20 yesipiliyoni sokukhiqiza ama-valve, abaklami bobunjiniyela abahle kakhulu kanye nabasebenzi bokukhiqiza, ama-valve asezingeni eliphezulu anconywa kakhulu. Sizoqhubeka nokuhlinzeka ngohlelo lokuthenga ama-valve olufanele kakhulu kumakhasimende adinga usizo, futhi sibheke phambili ekubambisaneni okwengeziwe!
