A Check Valveivharuvhu inovhurika nekuvhara dhisiki yevharuvhu nekuyerera kwepakati pachayo kudzivirira yepakati kuti isayerera ichidzoka. Inonziwo valve isingadzoki, imwe nzira yevhavha, reverse flow valve kana back pressure valve. Cheki vharuvhu ndeyechikamu che otomatiki mavharuvhu. Basa rayo guru nderokudzivirira yepakati kubva pakuyerera ichidzoka, kudzivirira pombi uye motokari yemotokari kubva pakudzokera shure, uye kusunungura mudziyo wepakati. Mukuwedzera, cheki chevhavha inogonawo kushandiswa pane pombi inopa kugovera kune yekubatsira hurongwa uko kudzvinyirira kunogona kukwira kudarika kudzvinyirira kwehurongwa.
Kushanda nheyo yevhavhavhavha
Chikamu chekuvhura uye chekuvhara chevhavhavhavhavhavhavhavhavhavhavha disc, iyo inoshanda nekuyerera kwekumanikidza kwepakati pachayo uye kufa kwevhavha disc kuvhara kumashure kwepakati. Kana iyo yepakati ichiyerera ichibva kumagumo ekupinza, dhisiki yevharuvhu inosundirwa yakavhurika uye yepakati inogona kupfuura zvakanaka; apo iyo yepakati inoyerera ichidzoka, dhisiki yevharuvhu inovhara nekufa uye kuyerera kwekudzivirira kudzivirira yepakati kubva pakuyerera kumashure.
Kurongwa kwecheki mavharuvhu
Cheki mavharuvhu anogona kukamurwa muzvikamu zvinotevera zvinoenderana nechimiro chavo uye nzira yekuisa:
Simudza cheki vharafu:
Ivhavha disc inotsvedza ichitevedza mutsetse wepakati wepakati pemuviri wevharuvhu, yakakodzera kune yakachinjika mapaipi, uye ine hombe yemvura inodzivirira.
Swing cheki vharafu:
Ivhavha disc ine disc-shaped uye inotenderera ichitenderedza shaft inotenderera yevharuvhu chigaro chiteshi. Iyo yekuyerera inopikisa idiki uye yakakodzera kune yakakura-dhayamita zviitiko ine yakaderera kuyerera mwero uye isingawanzo kuyerera shanduko.
Wafer cheki vharafu:
Ivhavha disc inotenderera ichitenderedza pini shaft muchigaro chevharuvhu. Iine chimiro chakareruka uye inogona kuiswa chete pahorizontal pombi. Kuisa chisimbiso kwakashata.
Pipeline cheki vharafu:
Ivhavha disc inotsvedza ichitevedza mutsara wepakati wemuviri wevharuvhu. Iine saizi diki, uremu huremu uye yakanaka yekugadzirisa tekinoroji.
Compression check valve:
Iine mabasa akazara evhavha yekusimudza cheki uye yekumisa vharafu kana yekona valve.
Maitiro ekushandisa
Tarisa mavharuvhuanoshandiswa zvakanyanya muzviitiko zvakasiyana-siyana pazvinenge zvakakodzera kudzivirira kudzoka kwezvinobudisa nhau, zvakadai sevharuvhu yepasi yemudziyo wekupomba, kubuda kwepombi, uye hurongwa hwekubuda kwemudziyo wemudziyo. Nekuda kwekuvhura kwayo otomatiki nekuvhara maitiro, iyo cheki vharafu inogona kudzivirira zvinobudirira kudzoreredza kwe media muzviitiko izvi uye kuchengetedza yakajairika mashandiro emidziyo uye masisitimu.
