Hlola umtsetfo wekusebenta kwevalvi, kuhlukaniswa kanye netinyatselo tekufaka

Indlela yekuhlola i-valve lesebenta ngayo

Ihlola ivalvu isetjentiswa eluhlelweni lwemaphayiphi, futsi umsebenti wayo lomkhulu kuvikela kubuyela emuva kwemkhatsi, kujikeleta lokubuyela emuva kwempompi kanye nemoto yayo yekushayela, kanye nekukhishwa kwemkhatsi esitjeni.

Hlola emavalvu ingaphindze isetjentiswe emigceni lephakela tinhlelo letisitako lapho khona umfutfo ungakhuphuka ngetulu kwemfutfo weluhlelo loluyinhloko. Hlola emavalvu angasetjentiswa kumaphayiphi etindzaba letehlukene ngekuya kwetintfo letehlukene.

Ivalve yekuhlola ifakwa kulephayiphi bese iba ngulenye yetintfo letimanti tephayiphi lephelele. Inchubo yekuvula nekuvala kwe-valve disc itsintseka ngesimo sekugeleza kwesikhashana seluhlelo lapho likhona khona; ngekulandzelana, timphawu tekuvala te-valve disc kukhona Inemtselela esimeni sekugeleza kwemanti.

Hlola kuhlukaniswa kwemavalvu

1. Swing ivalvu yekuhlola

I-disc ye-swing check valve isesimeni se-disc futsi ijikeleta ishaft yesiteshi sesihlalo se-valve. Ngenca yekutsi umsele lose valve ulungisiwe, kumela kwekugeleza kuncane kunaleyo yevalve yekuhlola yekuphakamisa. Ilungele emazinga laphansi ekugeleza kanye netingucuko letingakavami tekugeleza. Nomakunjalo, akukafaneli kugeleta lokushayako, futsi kusebenta kwayo kwekuvala akusiko lokuhle njengalokweluhlobo lwekuphakamisa.

Le valve yekuhlola yekujika ihlukaniswe yaba tinhlobo letintsatfu: luhlobo lwe-lobe yinye, luhlobo lwe-lobe lembili kanye neluhlobo lwe-lobe leningi. Lawa mafomu lamatsatfu ahlukaniswe kakhulu ngekuya kwebubanti bevalve.

2. Phakamisa ivalvu yekuhlola

I-valve yekuhlola lapho khona i-valve disc ishelela khona eceleni kwemgca losemkhatsini lomile wemtimba we-valve. Le valve yekuhlola yekuphakamisa ingafakwa kuphela ephayiphini levundlile, futsi ibhola lingasetjentiswa ku disc ye valve ku valve yekuhlola lenebubanti lobuncane lenemfutfo lomkhulu. Indlela yemtimba we valve ye valve yekuhlola yekuphakamisa iyafana naleyo ye valve ye globe (ingasetjentiswa ngekufana ne valve ye globe), ngako-ke i-coefficient yayo yekumelana nemanti inkhulu. Isakhiwo sayo sifana ne-valve ye-globe, futsi umtimba we-valve kanye ne-disc kuyafana ne-valve ye-globe.

3. Ivalvi yekuhlola luvivane

I-valve yekuhlola lapho khona le-disc ijikeleta khona i-pin esihlalweni. I-disc check valve inesakhiwo lesilula futsi ingafakwa kuphela kuphayiphi levundlile, futsi kusebenta kwekuvala akukalungi.

4. Ivalvu yekuhlola emaphayiphi

I-valve lapho khona le-disc ishelela khona emgceni losemkhatsini wemtimba we-valve. Ivalve yekuhlola emaphayiphi yivalve lensha. Incane ngebukhulu, ilula ngesisindvo futsi inhle ngebuchwepheshe bekucubungula. Kuyinto enye yeticondziso tekutfutfukisa hlola valve. Kepha, i-coefficient yekumelana nemanti inkhulu kancane kunaleyo ye-swing check valve.

5. Ivalve yekuhlola kucindzeteleka

Loluhlobo lwevalve lusetjentiswa njengemanti ekudla kwebhoyila kanye nevalve yekusika umfutfo, inemsebenti lohlanganisiwe wekuphakamisa kuhlola valve kanye nevalve yemhlaba noma valve ye-angle.

Ngetulu kwaloko, kunemavalvu ekuhlola langakulungeli kufakwa kwekuphuma kwempompi, njengevalve yetinyawo, luhlobo lwentfwasanhlobo, luhlobo lwe-Y, njll.
