Cheki mavharuvhu, anozivikanwawo seasingadzoke mavharuvhu (NRVs), chikamu chakakosha chechero maindasitiri kana pekugara pombi dzemvura. Iwo anoshandiswa kudzivirira kudzoka shure, kuve nechokwadi chekushanda kwehurongwa uye kudzivirira kukanganisa.

Cheki mavharuvhu anoshanda zviri nyore. Kumanikidzwa kwakagadzirwa nemvura inoyerera kuburikidza nepiping system inovhura vharuvhu, uye chero reverse inoyerera inovhara valve. Inobvumira fluid kuyerera zvachose isina kuvharika munzira imwe uye inodzima otomatiki kana kudzvanywa kwadzikira. Nepo izvi zviri nyore, kune marudzi akasiyana echeki mavharuvhu ane mashandiro akasiyana uye mashandisirwo. Unoziva sei kuti ndeupi rudzi rwecheki valve yekushandisa mubasa rako kana chirongwa? Kuti ikubatsire kuita sarudzo yakanaka, heano mamwe emhando dzemhando dzakajairika dzemavharuvhu ekutarisa.

Swing cheki vharafu
Iyo White PVC Swing CheckSwing Check Valve inoshandisa dhisiki mukati mevharuvhu kubvumira kana kumisa kuyerera mupombi system. Kana mvura ichiyerera nenzira kwayo, dzvinyiriro inomanikidza dhisiki kuti rivhure uye rirambe rakavhurika. Sezvo kudzvinyirira kunoderera, valve disc inovhara, ichidzivirira reverse kuyerera kwemvura. Swing cheki mavharuvhu anowanikwa mumhando dzakasiyana dzezvinhu, kusanganisira PVC, CPVC, yakajeka, uye maindasitiri.

Kune marudzi maviri e swing cheki mavharuvhu atinofanira kutarisa paari:

• Top Hinged - Mune iyi swing check valve, disc inosungirirwa kumusoro kwemukati wevhavha nehinge inobvumira diski kuzarura nekuvhara.

• Swashplate - Iyi swing check valve yakagadzirwa nenzira inobvumira kuti valve ivhure zvakakwana uye ivhare nokukurumidza pakuderera kwekuyerera. Inoita izvi ichishandisa chitubu-chakaremerwa dome-shaped disc kubvumira vharafu kuvhara nekukurumidza kupfuura vheji yepamusoro-hinged. Pamusoro pezvo, dhisiki iri mune ino cheki vharafu inoyangarara, saka mvura inoyerera pamusoro uye pasi peiyo disc.
Aya marudzi emavharuvhu ekutarisa anonyanya kushandiswa kudzivirira mafashama mumaseji system uye maapplication ekudzivirira moto. Anoshandiswa mumasisitimu anofambisa zvinwiwa, magasi uye mamwe marudzi enhau.

Simudzacheki vharafu
Simudza cheki mavharuvhu akanyanya kufanana nemavharuvhu epasi. Vanoshandisa pistons kana mabhora panzvimbo yemadhisiki anoshandiswa nemavharuvhu ekutenderera. Simudza cheki mavharuvhu anoshanda zvakanyanya pakudzivirira kudonha kupfuura swing cheki mavharuvhu. Ngatitarisei aya maviri ekusimudza cheki mavharuvhu:

• Piston - Iri rudzi rwevhavha yekuongorora inonziwo plug check valve. Iyo inodzora kuyerera kwemvura mumapombi masisitimu kuburikidza nemutsara wekufamba kwepiston mukati mekamuri yevharuvhu. Dzimwe nguva piston ine chitubu chakabatanidzwa, iyo inobatsira kuti irambe iri panzvimbo yakavharwa kana isiri kushandiswa.

Pachena PVC Bhora Tarisa Bhora Vhoravha • Vhuru yeBhora - Vhuru yekuongorora bhora inoshanda nekungoshandisa simba rinokwevera zvinhu pasi. Kana paine kumanikidzwa kwakakwana mumvura, bhora rinosimudzwa kumusoro, uye kana kudzvinyirira kwaderedzwa, bhora rinodonha pasi uye rinovhara kuvhura. Bhora cheki mavharuvhu anowanikwa mumhando dzakasiyana dzemhando uye maitiro emhando: PVC: yakajeka uye grey, CPVC: yechokwadi kubatana uye compact.

Simudzacheki mavharuvhuanoshandiswa mune zvakawanda maapplication mumaindasitiri mazhinji. Unovawana munzvimbo dzekugara uye dzemaindasitiri. Zvinoshandiswa muindasitiri yechikafu nechinwiwa, indasitiri yemafuta negasi, uye indasitiri yemugungwa, kutaura zvishoma.

Butterfly cheki vharafu
Shavishavi rinotarisa vharuvhu rakasiyana pakuti dhisiki raro rinopeta nepakati kuti mvura ibude. Kana kuyerera kwadzoserwa, mahafu maviri anovhurazve kuti aname vharafu yakavharwa. Iyi cheki vharafu, inozivikanwawo sevhavha yeplate yekutarisa kana kupeta disc cheki vharafu, yakakodzera kune yakaderera pressure fluid masisitimu pamwe negasi pombi masisitimu.

Globe cheki vharafu
Kuvhara-cheki mavharuvhu anobvumidza iwe kutanga uye kumisa kuyerera mune pombi system. Ivo vanosiyana pakuti ivo vanokubvumidza iwe kudzora traffic. A globe cheki vharafu inongova cheki vharafu ine override control inomira kuyerera zvisinei nekuyerera kana kudzvanywa. Kana kumanikidzwa kwanyanya kuderera, cheki chevhavha inovhara pakarepo kudzivirira kudzoka shure. Rudzi urwu rwevhavhavha yekuongorora inogona kushanda uchishandisa kunze kwekutonga panzvimbo yekutonga kwepamusoro, izvo zvinoreva kuti iwe unogona kuisa valve panzvimbo yakavharwa pasinei nekuyerera.

Globe cheki mavharuvhu anonyanya kushandiswa muma boiler masisitimu, zvidyarwa zvemagetsi, kugadzirwa kweoiri uye yakanyanya kudzvanywa kuchengetedza maapplication.

Pfungwa dzekupedzisira paCheck Valves
Kana zvasvika pakudzivirira kudzoka shure, hapana sarudzo kunze kwevhavha yekutarisa. Iye zvino zvaunoziva zvishoma nezvemhando dzakasiyana dzecheki mavharuvhu, iwe unofanirwa kukwanisa kusarudza kuti ndeipi yakanakira application yako.
