Mavharuvhu emashavishavi ane bidirectional?

Butterfly Valve imhando yedhivha yekudzora kuyerera ine quarter-turn rotational motion , Inoshandiswa mumapaipi kudzora kana kupatsanura kuyerera kwemvura ( zvinwiwa kana magasi ) , Zvisinei, A good quality and performance butterfly valve inofanira kunge ine chisimbiso chakanaka. . Mavharuvhu eshavishavi ari kudivi reviri here? Kazhinji tinopatsanura vharuvhu yeshavishavi kuva Concentric butterfly valves uye eccentric butterfly valve .
Tichakurukura nezve concentric butterfly valve bidirectional sepazasi:

Chii chinonzi Concentric butterfly valve?

Concentric butterfly valve know as resilient seated or zero-offset butterfly valves , Nhengo dzayo dzinosanganisira :Valve body , disc , seat , stem and seal shaft kana dzinde riri pakati pedhisiki . Izvi zvinoreva kuti dhisiki inotenderera mukati mechigaro chakapfava, Chigaro chechigaro chinogona kusanganisira EPDM, NBR Viton Silicon Teflon Hypalon kana elastomer.

Nzira yekushandisa sei concentric butterfly valve?

Kuvakwa kwevhavhavhavhavha iri nyore , kune nzira nhatu dze actuator yekushanda :Lever Handle yehukuru hudiki , Worm Gear box yeLarger valves kuti zvive nyore kudzora uye Automated operation (inosanganisira Magetsi uye Pneumatic Actuators)
Varuvhu yeshavishavi inoshanda nekutenderedza dhisiki (kana vane) mukati mepombi kudzora kuyerera kwemvura. Iyo dhisiki yakaiswa pane hunde inopfuura nepakati pemuviri wevhavha, uye kushandura tsinde inotenderedza dhisiki kuvhura kana kuvhara vharafu, Sezvo shaft ichitenderera, dhisiki inotendeuka yakavhurika kana chikamu chakavhurika chinzvimbo, ichibvumira mvura kuti ifambe zvakasununguka. Munzvimbo yakavharwa, Shaft inotenderera disc kuvhara kuyerera zvachose uye kuvhara vharafu.

Mavharuvhu eshavishavi ari kudivi reviri here?

Bidirectional -zvinoreva zvinogona kudzora kuyerera kumativi ose maviri, Sezvatakataura, mavharuvhu anoshanda musimboti anogona kusvika kune zvinodiwa .Saka concentric butterfly mavharuvhu ari bidirectional, Pane zvakawanda zvakanakira kushandisa concentric butterfly valve.
1 Iyo ine mari yakawanda kupfuura mamwe marudzi evharuvhu nekuda kwekugadzirwa kwayo kuri nyore uye zvishoma zvinhu zvinodiwa pakuvaka. Kuchengetedza mari kunonyanya kuoneka muhukuru hwevharuvhu.
2 Kushanda nyore, kuisa uye kugadzirisa, iyo concenric butterfly valve nyore inoita kuti zvive nyore uye nekukurumidza kuisa, inogona kuderedza mutengo wevashandi, Yakareruka, dhizaini yehupfumi ine zvikamu zvishoma zvinofamba, uye nekudaro zvishoma zvekupfeka, zvinoderedza zvakanyanya kuchengetedza kwavo. zvinodiwa.
3 Iyo yakareruka uye compact dhizaini uye diki kumeso nechiso chiyero cheiyo concentric butterfly valve, Inogonesa kuiswa uye kushandiswa munzvimbo-inogumira nharaunda, Inoda nzvimbo shoma kana ichienzaniswa nedzimwe mhando dzevharuvhu, senge gedhi kana globe mavharuvhu, uye compactness yavo inorerutsa. zvese kuisirwa nekushanda, kunyanya mumasisitimu akazara.
4 Inokurumidza kuita, iyo yekurudyi-kona (90-degree) inotenderera dhizaini inopa nekukurumidza kuvhura nekuvhara. Chimiro ichi chakakosha mumaapplication apo mhinduro yekukasira yakakosha, senge mukuvharwa kwechimbichimbi masisitimu kana maitiro ane chaiwo ekutonga zvinodiwa. Kugona kuvhura nekuvhara nekukurumidza kunowedzera kuterera kwehurongwa, zvichiita kuti mavharuvhu eshavishavi anyanyokodzera kuyerera nekuyerera uye pa/kudzima kutonga muzvirongwa zvinoda nguva yekuita.

Pakupedzisira, iyo bidirectional butterfly valve ine nzira mbiri yekuisa chisimbiso nekuda kweiyo elastic sealing structure pakati pechigaro chevharuvhu nedhisiki re butterfly, Kuona kuvharika kwakafanana zvisinei nekuyerera kwemvura.
