Tarisa vharafu, inozivikanwawo sevhavha yenzira imwe chete kana cheki chevhavha, ndeyechikamu cheotomatiki chevharuvhu, uye basa rayo nderekudzivirira kuyerera kwepakati mupombi.Ivhavha yepasi inoshandiswa pakusveta pombi imhando yevhavha yekuongorora.Iyo dhisiki yevhavha yekutarisa inovhurwa pasi pechiito chekumanikidza kwemvura, uye mvura inoyerera ichibva painopinda ichienda kune inobuda.Kana iyo inlet pressure yakadzikira pane yekubuda, iyo valve flap inovharika otomatiki pasi pechiito chemvura yekumanikidza musiyano, giravhiti uye zvimwe zvinhu kudzivirira mvura kuti isayerera ichidzoka.
Kurongeka kwemavharuvhu echeki kunogona kukamurwa kuva marudzi akasiyana zvichienderana nezvinhu, basa uye chimiro.Izvi zvinotevera zvinounza marudzi echeki mavharuvhu kubva pazvinhu zvitatu izvi.
1. Kuronga maererano nezvinhu
1) Kanda simbi yekuongorora valve
2) Brass check valve
3) Stainless simbi yekutarisa valve
2. Kurongeka nebasa
Ball check valve inonziwo sewage check valve.Muviri wevharuvhu unotora chimiro chakazara chechiteshi, chine zvakanakira kuyerera kukuru uye kushomeka kushomeka.Bhora rinoshandiswa sevhavha disc, iyo inokodzera maindasitiri uye epamba epaipi pombi network ine yakakwira viscosity uye yakaturikwa yakasimba.
3. Kurongwa nechimiro
Mamiriro evhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhamuhuro rinowanzofanana neaya evharuvhu.Ivhavha disc inofamba ichikwira uye ichidzika nemutsara muchiteshi, uye chiito chakavimbika, asi kupikisa kwemvura kwakakura, uye yakakodzera nguva dzine madhayamita maduku.Simudza cheki vharafu yakakamurwa kuita marudzi maviri: yakachinjika mhando uye yakatwasuka mhando.Kutwasanuka-kuburikidza nekusimudza cheki mavharuvhu anogona kazhinji kuiswa pamapaipi akachinjika, nepo vertical cheki mavharuvhu uye ezasi mavharuvhu anowanzo kuisirwa pamapaipi akatwasuka, uye yepakati inoyerera kubva pasi ichienda kumusoro.
Iyo disc ye swing cheki valve inotenderera ichitenderedza axis yekutenderera.Kupokana kwayo kwemvura kunowanzo kudiki pane iyo yevhavha yekutarisa, uye inokodzera zviitiko zvine madhayamita akakura.Zvinoenderana nehuwandu hwemadhisiki, swing cheki vharafu inogona kukamurwa kuita marudzi matatu: single disc swing type, kaviri disc swing mhando uye akawanda disc swing mhando.Single flap swing cheki vharafu inowanzokodzera zvepakati dhayamita zviitiko.Kana imwe chete flap swing check valve inoshandiswa pamapaipi makuru-diameter, kuitira kuderedza nyundo yemvura, zviri nani kushandisa inononoka-kuvhara cheki valve inogona kuderedza nyundo yemvura.Double flap swing cheki vharafu yakakodzera kune hombe uye yepakati dhayamita mapaipi.Wafer kaviri flap swing cheki vharafu idiki muchimiro uye yakareruka muhuremu, uye imhando yevharuvhu yekutarisa nekukurumidza kukura.Multi-lobe swing cheki vharafu yakakodzera kune yakakura dhayamita mapaipi.
Nzvimbo yekuisa ye swing check valve haina kuganhurirwa, inowanzoiswa pahorizontal pipeline, asi inogonawo kuiswa pa vertical pipeline kana pombi yekurasa.
Mamiriro evharuvhu ekuongorora shavishavi akafanana neevharuvhu yeshavishavi.Chimiro chayo chiri nyore, kuyerera kwekuyerera kudiki, uye nyundo yemvura inomanikidza zvakare idiki.
Nzira dzekubatanidza dzecheki valve dzinosanganisira clip connection, flange connection, threaded connection, butt welding/socket welding connection, etc. Iyo inoshandiswa tembiricha range ndeye -196℃~540℃.Valve muviri zvinhu zviri WCB, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L).Sarudza zvinhu zvakasiyana zvema media akasiyana.Cheki vharafu inogona kuiswa kumvura, chiutsi, mafuta, nitric acid, acetic acid, oxidizing svikiro, urea uye mamwe midhiya.
Paunenge uchiisa cheki valve, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune kuyerera kwepakati, uye yakajairika kuyerera kwepakati kunofanirwa kuenderana nekutungamira kwemuseve wakaratidzwa pamutumbi wevhavha, zvikasadaro kuyerera kwakajairika kwepakati kuchaita. kugurwa.Ivhavha yepasi inofanira kuiswa pamucheto wezasi wemutsara wekusveta wepombi.
Kana vheji yekuongorora yakavharwa, nyundo yemvura inomanikidzwa ichagadzirwa mupombi, iyo inokonzera kukuvadza kwevhavha, pombi kana midziyo mumatambudziko akaoma, kunyanya kune muromo mukuru-mapaipi kana mapipe e-high-pressure, tapota nyatsoteerera.
