Cheki vharafu ndeyekuvimba nekuyerera kwepakati pachayo uye otomatiki kuvhura uye kuvhara vharafu disc, inoshandiswa kudzivirira media kuyerera kumashure valve, inozivikanwawo secheki vharafu, imwe-nzira vharafu, countercurrent valve, uye back pressure valve.
Tarisa chiito chevharuvhu
Cheki vharafu imhando yeotomatiki vharafu, basa rayo guru nderekudzivirira midhiya kudzoka, kudzivirira pombi uye dhiraivha mota reverse, pamwe nekubuda kwemudziyo wepakati.Cheki mavharuvhu anogona zvakare kushandiswa kugovera mitsara umo kumanikidza kunogona kusimuka kuti ipfuure kudzvanywa kwehurongwa mune yekubatsira system.
Kurongwa kwecheki mavharuvhu
Cheki mavharuvhu anogona kukamurwa zvichienderana nechimiro chavo uye kuiswa:
1. Swing check valve
Swing check valve disc disc, inotenderera ichitenderedza chigaro chevharuvha chiteshi chevhavha yekufamba-famba, nekuti chiteshi chevhavha ichienda kune mutsara kuyerera, kuyerera kwekudzivirira kudiki pane yekusimudza cheki vharafu, inokodzera yakaderera kuyerera kwevelocity uye kuyerera kwete kazhinji shanduko yeakakura madhayamita zviitiko. , asi kwete yekupuruzira kuyerera, kuita kwayo yekuisa chisimbiso hakuna kunaka sekusimudza.Swing cheki vharafu yakakamurwa kuita imwechete, kaviri nehafu mhando nhatu, idzi mafomu matatu anonyanya kukamurwa zvichienderana nedhayamita yevharuvhu, chinangwa ndechekudzivirira yepakati kumira kuyerera kana kudzosera kuyerera, kunetesa iyo hydraulic impact.
2. Simudza cheki valve
Dhisiki pamwe chete nepakati pepakati mutsara wevharuvhu yemuviri slide cheki vharafu, inosimudza cheki vharafu inogona kungoiswa muhorizontal pombi, mumhepo yakakwira dhayamita dhayamita cheki dhisiki yevharuvhu inogona kushandiswa mubhora.Simudza cheki cheki vharuvhu chimiro uye globe vharafu (inogona kushandiswa neglobe vharafu), saka yayo yemvura inodzivirira coefficient yakakura.Chimiro chacho chakafanana nevhavha yepasi, uye muviri wevhavha uye disc zvakafanana nevhavha yepasi.Chikamu chepamusoro chevhavha disc uye chikamu chezasi chechivharo chevhavha chinogadziriswa negwatidziro sleeve, iyo valve disc inotungamira pepa inogona kusununguka kusimuka uye kuwira muvhavha rambi rekutungamira pepa, kana yepakati yakadzika pasi, iyo valve disc by. iyo yepakati inopinza yakavhurika, kana yepakati inomira ichiyerera, vharafu disc nekumira yakatwasuka pachigaro, kudzivirira yepakati countercurrent maitiro.Yakatwasuka-kuburikidza nekusimudza cheki vharafu yepakati inlet uye yekubuda chiteshi nzira uye vharafu chigaro chiteshi nzira yakatwasuka;Vertical lift cheki vharafu, yepakati pekupinza uye yekubuda chiteshi kutungamira uye chigaro chiteshi kutungamira kwakafanana, kuyerera kwekudzivirira kudiki pane kutwasuka-kuburikidza.
3. Disc check valve
A cheki valve umo dhisiki inotenderera ichitenderedza pini pachigaro.Disc cheki vharafu chimiro chiri nyore, chinogona kuiswa chete muhorizontal pombi, isina kuvharwa chisimbiso.
4. Pipe check valve
Valve apo disc inotsvedza pamwe nepakati pemuviri.Pipe cheki vharafu ivharuvhu nyowani, vhoriyamu yayo diki, uremu huremu, yakanaka yekugadzirisa tekinoroji, ndeimwe yenzira yekuvandudza yevhavhavhavha.Asi iyo fluid resistance coefficient yakakura zvishoma pane swing check valves.
5. Pressure check valve
Iri vharafu rinoshandiswa kune boiler yekudyisa mvura uye chiutsi chakachekwa vharafu, ine yekusimudza cheki vharafu uye globe vharafu kana Angle valve yakabatanidzwa basa.
Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
