isicelo

Cishe zonke izinhlelo zokusebenza zokuthutha ngamapayipi noma ngoketshezi ezingacatshangwa, kungaba zezimboni, zezentengiselwano noma zasekhaya, ziyasetshenziswaama-valve okuhlola. Ziyingxenye ebalulekile yokuphila kwansuku zonke, nakuba zingabonakali. Izimboni zendle, ukwelashwa kwamanzi, ukwelashwa kwezokwelapha, ukucubungula amakhemikhali, ukukhiqizwa kukagesi, ikhemisi, i-chromatography, ezolimo, amandla kagesi, i-petrochemical kanye nezimboni zokucubungula ukudla neziphuzo zisebenzisa ama-check valve emisebenzini yazo yansuku zonke ukuze zivimbele ngempumelelo ukugeleza kwamanzi emuva. Ngenxa yokuthi zivimbela ukwehluleka komkhiqizo futhi azidingi ukubhekwa ngesikhathi sokusebenza, ama-check valve awafiseleki nje kuphela, kodwa ngokuvamile ayadingeka ngokomthetho ukuqinisekisa ukuphepha kwamanzi, igesi, kanye nokusetshenziswa kwengcindezi.

Ekhaya, ziyasiza ekuqaliseni nasekumiseni ukugeleza koketshezi. Zisetshenziswa kuma-heater amanzi, kumapayipi angaphakathi, kuma-faucet kanye nasemishinini yokuwasha izitsha, kanye nasemishinini ethuthukisiwe njengephampu yokulinganisa, kuma-mixer, kuma-mixer kanye namamitha okugeleza. Ama-valve okuhlola ezimboni aqapha izinhlelo ze-nuclear, embonini, ezimbonini zamakhemikhali, ezinhlelweni ze-hydraulic zezindiza (izinga lokushisa lokudlidliza kanye nezinto ezibolayo), izinhlelo zezindiza zasemkhathini kanye nezimoto zokuqalisa (ukulawula ukusabela, ukulawula i-propellant, ukulawula ukuphakama), kanye nezinhlelo zokulawula ukugeleza komoya (ukuvimbela ukuxubana kwegesi)

izici

Ama-valve okuhlola aya ngokuya ethandwa kakhulu ngenxa yokwakheka kwawo okulula kanye nokulula kokusetshenziswa. Indlela yokusebenza ilula kakhulu. Njengoba kushiwo ngaphambili, ukusebenza kwe-valve yokuhlola kunqunywa ngokuphelele ukugeleza kwenqubo, okusho ukuthi akukho actuator eyengeziwe edingekayo. Ngokuvamile, i-valve isebenza njengedivayisi eyindilinga exhunywe ekhanda lephampu emigqeni yokungena kanye neyokuphuma. Idivayisi esebenzayo enezimbobo kuzo zombili izinhlangothi inqamula igobolondo futhi ihlukanise igobolondo libe izingxenye ezingenhla kanye nezingezansi. Isihlalo se-valve sisuka odongeni lwesilinda, kodwa sinomgodi ofanele ukugeleza kwenqubo.

Ibhola, ikhoni, idiski noma enye idivayisi enkulu kakhulu ihlezi esihlalweni sevalvu ohlangothini olungezansi lwevalvu yokuhlola. Ukuhamba okulinganiselwe kuvimbela idivayisi yokuxhuma ukuthi ingashiswa phansi. Lapho uketshezi luhamba ngendlela enqunyiwe ngaphansi kwengcindezi edingekayo, ipulaki liyasuswa esihlalweni sevalvu bese uketshezi noma igesi kuvunyelwa ukuthi kudlule esikhaleni esiphumayo. Njengoba ukucindezela kwehla, ipulaki libuyela esihlalweni ukuvimbela ukugeleza emuva.

Izindlela zokulayisha iziphethu zamandla adonsela phansi noma zensimbi engagqwali ngokuvamile zibangela lokhu kubuyela emuva, kodwa kwezinye izimo, ingcindezi eyengeziwe ohlangothini olungezansi lwevalvu yanele ukuhambisa imishini ibuyele endaweni yayo yokuqala. Ukuvalwa kwevalvu kuvimbela izinto ezingezansi ukuthi zingahlangani nezinto ezingenhla ngisho nalapho ingcindezi ikhuphuka. Ama-plug athile asetshenziswayo ayahlukahluka kuye ngohlobo lwevalvu yokuhlola efakiwe. Njengoba igama lisho,ukusetshenziswa kwama-valve okuhlola ibholaAmabhola. Amavalvu okuhlola ukuphakama asebenzisa amakhoni noma amadiski anamathiselwe eziqondisweni zenduku ukuqinisekisa ukuthi abuyela endaweni efanele esihlalweni sevalvu. Amavalvu okujika kanye ne-wafer asebenzisa idiski elilodwa noma amaningi ukuvala isikhala esihlalweni.

Izinzuzo ze-check valve

Ama-valve okuhlola anezinzuzo eziningiOkokuqala, zingalawula ukugeleza kwe-psi emikhakheni eyahlukene yezimboni. Eqinisweni, zingasebenza ngomfutho we-psi ophezulu ngokwanele ukucima umlilo, kanti umfutho we-psi ulawulwa ngokwanele ukusebenza kusilinda se-scuba. Enye inzuzo yama-check valve ukuthi avimbela ukungcoliswa koketshezi oluhambayo, okuhlanganisa namanzi ahlanzekile.
