Common Valve Knowledge I

一 Butterfly valve

Disiki reshavishavi vharuvhu idhisiki, rinotenderera rakatenderedza akisi pachigaro. Iko kona yekutenderera ndiyo dhigirii yekuvhura nekuvhara yevhavha. Mabhenefiti ayo akareruka, chimiro chakareruka, kuchengetedza zvinhu zvichienzaniswa nemamwe mavharuvhu, kuvhura nekukurumidza nekuvhara, kucheka uye kupuruzira kunogona kushandiswa, kushomeka kwemvura kudiki, kushanda kuri kuponesa basa, kunogona kuitwa muhombe caliber. Butterfly mavharuvhu anoshandiswa zvakanyanya mumapaipi emvura inopisa. Iko mavhavhavha evhavhavha anogona kushandiswa, zviri nani kusashandisa mavharuvhu emagedhi, nekuti mavharuvhu e butterfly ane hupfumi kupfuura mavharuvhu emagedhi uye ane mutemo wakanaka.

2 Diaphragm valve

Iyo diaphragm valve inoshandiswa kutsaura nzira yemhepo nekudzvanya elastomer firimu zvine simba pachigaro nehunde yevharuvhu. Kutenderedza vhiri reruoko kunogona kutyaira dzinde kumusoro nekudzika, kuitira kuti diaphragm ibve pachigaro kuti ivhure vharafu kana kuita kuti diaphragm itsike zvakasimba pachigaro kuti ivhare valve. Nguva dzekushandiswa kwayo imvura yakanyanyisa-yakachena, mvura yakanyanyisa-yakachena haidi kona yakafa mupombi inoyerera; chechipiri, kune kusvibiswa kwetsvina yetsvina, mhinduro, nezvimwewo, chidimbu bhora vharafu mumvura iri nyore kupfeka uye kubvarura uye kubuda, kuvharika kwepamusoro nepasi kwevhavhavhavhavha inodzivirira zvakanyanya dambudziko iri, uye diaphragm inogona kutsiviwa mushure menguva refu- kushandiswa kwenguva.

Three angle valve

Angular valve body yakaringana-kurudyi, muviri wevharuvhu une chigaro uye chisimbiso chepamusoro, kazhinji chepasi mukati nekunze. Iyo utility modhi ine zvakanakira chimiro chakareruka uye yakanaka yekuisa chisimbiso maitiro. Nekuzvichenesa, muviri wevharuvhu hausi nyore kuunganidza tsvina, isingakodzeri plugging, yakakodzera kudzora midhiya yakakwira viscosity, mutsauko wekumanikidza uye midhiya ine nyaya yakamiswa uye nyaya. Izvo zvisingabatsiri ndezvekuti zvinowanzoitika kune isina kugadzikana valve core oscillation.

四 Pneumatic Film Regulating Valve

Iyo actuator yepneumatic film control valve ine yakanaka uye yakaipa mhedzisiro. Mhedzisiro yakanaka ndeyekuti kana kumanikidza kunowedzera, tsinde yevharuvhu inofamba ichidzika, uye kumanikidza kunopinda mukamuri yefirimu pamusoro peiyo corrugated diaphragm. Reaction inoreva kuti kana kumanikidza kunowedzera, hunde yevharuvhu inokwira kumusoro, uye kudzvanywa ndiyo kamuri yefirimu iri pasi peiyo corrugated diaphragm.
