Kushandiswa kwecheki vharafu
1. Swing check valve: Dhidhi yevhavha yekuvhara yevhavha yakaumbwa ne disc, uye inotenderera ichipoteredza shaft yevhavha yechigaro chevhavha.Nemhaka yokuti nzira yemukati yevhavha inogadziriswa, kuyerera kwekudzivirira kunowedzera.
Iyo yekudonha yekutarisa valve idiki, yakakodzera kuderera kuyerera kwevelocity uye yakakura dhayamita zviitiko uko kuyerera kusingachinjiki kazhinji, asi haina kukodzera kupuruzira kuyerera, uye kuita kwayo chisimbiso hakuna kunaka semhando yekusimudza.Swing cheki mavharuvhu akakamurwa kuva mhando nhatu, imwe-shizha mhando, kaviri-shizha mhando uye akawanda-hafu mhando.Aya marudzi matatu anonyanya kuiswa maererano nedhayamita yevharuvhu.Chinangwa ndechekudzivirira yepakati kumira kana kuyerera kumashure uye kuderedza iyo hydraulic shock.
2.Lifting check valve: cheki chevhavha iyo disc inotsvedza pamwe chete nepakati pepakati pemuviri wevhavha.Iyo yekusimudza cheki vharuvhu inogona kuiswa chete pane yakatwasuka pombi.Iyo disc inogona kushandiswa pane yakakwirira-kumanikidza diki-diameter cheki vharafu..Chimiro chemuviri wevhavha yevhavha yekusimudza cheki yakangofanana neyevhavha yekumira uye inogona kushandiswa pamwe chete nevhavha yekumisa, saka iyo inodzivirira mvura inokwana yakawanda.Chimiro chayo chakafanana nevhavha yekumisa, uye muviri wevhavha uye disc zvakafanana nevhavha yekumira.Chikamu chepamusoro chevhavhavha uye chikamu chezasi chebhoneti chinogadziriswa nemaoko ezwi.Iyo valve disc guide inogona kusimudzwa zvakasununguka uye kuderedzwa mugwara revhavha.Kana iyo yepakati ichiyerera ichidzika pasi, dhisiki yevharuvhu inovhura nekukanda kwepakati.Inodonhera pachigaro chevharuvhu kudzivirira yepakati kubva kuyerera ichidzokera kumashure.Iyo nzira yepakati pekupinda uye yekubuda chiteshi cheyakatwasuka-kuburikidza nekusimudza cheki cheki valve inotenderera kune inotungamira yechigaro chevhavha chiteshi;iyo vertical lifting check valve ine nzira imwechete yekupinza uye yekubuda migero sevhavha yechigaro chevhavha, uye kuyerera kwayo kunopesana kuduku pane iyo yakatwasuka-kuburikidza nemhando.
3. Disc check valve: cheki chevhavha umo dhisiki inotenderera yakakomberedza pini shaft muchigaro chevhavha.Iyo disc yekutarisa vharafu ine chimiro chakareruka uye inogona chete kuiswa pane yakatwasuka pombi, ine kusasimba kwekuisa chisimbiso kuita.
4. In-line cheki valve: Ivhavha ine disc inotsvedza pamwe nepakati pemuviri wevharuvhu.Iyo pipeline yekutarisa valve imhando itsva yevharuvhu.Idiki muhukuru uye yakareruka mukurema.
Kugadzirwa kwakanaka ndeimwe yenzira dzekusimudzira dzecheki mavharuvhu.Asi iyo fluid resistance coefficient yakakura zvishoma pane iyo ye swing check valve.
5. Compression check valve: Iyi valve inoshandiswa sevhavha yekudyisa mvura uye steam kuvhara-off valve.Iine basa rakazara rekusimudza cheki vharafu uye yekumisa vharafu kana angle valve.
Mukuwedzera, kune mamwe mavharuvhu ekutarisa asina kukodzera kuiswa kwepombi, zvakadai sevharuvhu yepasi, rudzi rwechitubu, Y-mhando uye mamwe mavharuvhu ekuongorora.
Nheyo yekushanda yevhavha yekuongorora
Cheki valve (Check valve) inoreva vharuvhu inovhurika nekuvhara dhisiki zvichienderana nekuyerera kwepakati pachayo kudzivirira yepakati kubva kuyerera kumashure, inozivikanwawo sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava,reverse flow valve uye back pressure valve.Cheki vharafu imhando ye otomatiki vharafu.Basa rayo guru nderekudzivirira yepakati kubva pakuyerera kumashure, kudzivirira pombi uye kutyaira mota kubva pakudzokera kumashure, uye kuburitsa mudziyo wepakati.Cheki mavharuvhu anogona zvakare kushandiswa kugovera mapaipi ekubatsira masisitimu uko kudzvanywa kunogona kukwira pamusoro pesimba rehurongwa.Cheki mavharuvhu anogona kukamurwa kuita swing cheki mavharuvhu anotenderera zvinoenderana nepakati pegiravhiti uye simudza cheki mavharuvhu anofamba achitevedza axis.Basa remhando iyi yevhavha yekuongorora ndeyekungobvumira svikiro kuyerera mune imwe nzira uye kudzivirira kuyerera kune imwe nzira.Kazhinji rudzi urwu rwevharuvhu runoshanda rwoga.Pasi pechiito chekumanikidza kwemvura kuyerera kune imwe nzira, vharafu yevhavha inovhura;apo mvura inoyerera ichienda kune imwe nzira, iyo mvura inodzvinyirira uye kuzvibata kwevhavha yevhavha inobata pachigaro chevhavha, nokudaro ichicheka kuyerera.Pakati pavo, cheki valve ndeyemhando iyi yevhavha, iyo inosanganisira swing check valve uye lift check valve.Iyo swing cheki vharafu ine hinge mechanism uye dhisiki yevharuvhu senge gonhi rakasununguka rakatsamira pane yakatemerwa chigaro chevharuvhu.Kuitira kuti ive nechokwadi chekuti chivharo chevhavha chinogona kusvika panzvimbo yakakodzera yechigaro chevhavha pese pese, iyo valve clack inogadzirwa mune hinge mechanism kuitira kuti iyo valve clack ive nenzvimbo yakakwana yekutendeuka uye inoita kuti vharafu inyatso uye ibatane zvachose. chigaro chevharuvhu.Iyo valve clack inogona kugadzirwa nesimbi, kana yakashongedzwa nedehwe, rabha, kana yekugadzira yekuvharisa, zvichienderana nekuita zvinodiwa.Kana iyo swing cheki vharafu yakavhurwa zvizere, iyo fluid pressure inenge isina kuvharika, saka kudonha kwemhepo kuburikidza nevharuvhu kudiki.Ivhavha disc yevhavha yekusimudza yevhavha inowanikwa panzvimbo yekuvhara yechigaro chevhavha pamutumbi wevhavha.Kunze kwekuti dhisiki yevhavha inogona kusimudzwa uye kuderedzwa zvakasununguka, valve yakafanana nevhavha yekuvhara.Iyo mvura inodzvinyirira inosimudza dhizaini yevhavha kubva pachigadziko chevhavha chisimbiso chepamusoro, uye yepakati backflow inoita kuti dhisiki yevhavha idonhe ichidzokera kuchigaro chevharuvhu uye ichigura kuyerera.Zvinoenderana nemamiriro ekushandiswa, iyo valve clack inogona kuve-yese-simbi chimiro, kana inogona kunge iri muchimiro cherabha padhi kana mhete yerabha yakaiswa pane valve clack frame.Kufanana nevhavha yepasi rose, kubuda kwemvura kuburikidza nevhavha yekusimudzira yekuongorora zvakare yakamanikana, saka kudonhedzwa kwemhepo kuburikidza nevhavhavhavha yekusimudzira yakakura kudarika iyo yevhavhavha yekuongorora, uye chiyero chekuyerera kwevhavha yekuongorora inobatwa.Zvinorambidzwa zvishoma.
Chechina, hunhu hweiyo wafer cheki valve:
1. Kureba kwechimiro ipfupi, uye chimiro chayo kureba ingori 1/4 ~ 1/8 chete yetsika flange cheki valve.
2.Small size, light weight, uye uremu hunongova 1/4 ~ 1/20 chete yetsika flange check valve.
3. Chivharo chevhavha chinovhara nokukurumidza uye nyundo yemvura inodzvinyirira iduku.
4. Mapaipi ese ari maviri akatwasuka kana vertical pombi anogona kushandiswa, nyore kuisa.
5. Nzira yekuyerera haina kuvharwa uye kupikisa kwemvura kuduku.
6. Sensitive action uye yakanaka yekuisa chisimbiso kuita.
7. Ivhavha disc ine short stroke uye zviduku zvekuvhara.
8. Chimiro chese chiri nyore uye chakabatana, uye chitarisiko chakanaka.
9. Hupenyu hurefu hwebasa uye kushanda kwakavimbika.
Basa revhavha yecheki mupombi yemvura yekupa hurongwa ndeyekudzivirira kukanganisa kwepamusoro-kumanikidzwa kwemvura kumashure kwepombi impeller.Munguva yekushanda kwegadziriro, apo pombi inongoerekana yamira kushanda nokuda kwechimwe chikonzero, kumanikidzika kwepombi kunopera, uye mvura yepamusoro-soro yakabatana nekubuda kwepombi inoyerera ichidzokera kune pombi nenzira yakadzokera kumashure.Kana pombi yepombi yakashongedzerwa nevhavhavha yekuongorora, ichavharwa pakarepo kudzivirira mvura yepamusoro-soro kuti irege kuyerera ichidzokera pombi.Basa revhavha yekuongorora mumvura inopisa ndeyekudzivirira mvura inopisa kuti irege kuyerera ichidzokera mupombi.Kana iri pombi yePVC, inogona kupisa pombi uye kunyange kukuvadza vanhu, kunyanya mumhepo inopisa mvura yezuva.
