Chii chinonzi abutterfly valve?
Butterfly valve inonzi butterfly valve nekuti chimiro chayo chakafanana neshavishavi.Iyo actuator inotenderedza ndiro yevhavha 0-90 madhigirii kuvhura nekuvhara vharafu, kana kugadzirisa muchidimbu chiyero chekuyerera.
Chii chinonzi abhora vharafu?
Mavharuvhu ebhora anoshandiswawo mumapaipi kudzora mavharuvhu anodzora kuyerera kwemvura.Ivo vanowanzo shandisa sphere ine gomba kudzora kuyerera kwemvura, iyo inogona kupfuura kana kuvharika sezvo sphere inotenderera.
Sezvinhu zvinodzora mvura, mavharuvhu eshavishavi uye mavharuvhu ebhora anogona kushandiswa kubatanidza nekucheka svikiro mupombi.Ndeipi misiyano, zvakanakira nekuipira?Pazasi tinoiongorora kubva kune chimiro, chiyero chekushandisa, uye chisimbiso zvinodiwa.
1. Chimiro nenheyo
- Chikamu chekuvhura nekuvhara chevhavhavhavhavhavhavhavhavhavhavhavhavhavharuvhu,sekureva kwazvinoita zita,ichipande chakaita seplate chine humwe ukobvu, ukuwo chikamu chekuvhura nekuvhara chevharuvhu yebhora ibhora.
- Butterfly mavharuvhu ari nyore uye ane compact chimiro, saka iwo akareruka mukurema;nepo mavharuvhu ebhora aine muviri wakareba uye anoda nzvimbo yakakura pakuvhura nekuvhara.Dzinowanzova dzakakura uye dzinorema.
- Kana vharuvhu yeshavishavi yanyatsovhurika, ndiro yevharuvhu inotenderera ichienda kwainoyerera, ichibvumira kuyerera kusingaganhurirwi.Kana shavishavi yevharuvhu yakavharwa, ndiro yevharuvhu iri perpendicular kudivi rekuyerera kwepakati, nokudaro ichivharira zvachose kuyerera.
- Kana vharuvhu yebhora yakazara yakazaruka, maburi anowirirana nepombi, zvichiita kuti mvura ipfuure.Uye kana yakavharwa, bhora rinotenderera 90 degrees, zvachose ichivharira kuyerera.Yakazara bore bhora vharafu inoderedza kudonha kwekumanikidza.
2. Chikamu chekushandiswa
- Butterfly mavharuvhu anogona chete kushandiswa maviri-nzira kuyerera;bhora mavharuvhu anogona zvakare kushandiswa senzira nhatu-diverters mukuwedzera kune maviri-nzira kuyerera.
- Butterfly mavharuvhu akakodzera on/off control of low-pressure pipeline media;bhora mavharuvhu anogona kushandiswa chaiyo kuyerera kudzora mune yepamusoro tembiricha uye kumanikidzwa mamiriro.
- Butterfly mavharuvhu anoshandiswa zvakanyanya mukuchenesa tsvina, kugadzira chikafu, maHVAC masisitimu, magadzirirwo emhepo uye mamwe minda;bhora mavharuvhu anonyanya kushandiswa peturu, gasi chaiwo, makemikari indasitiri, simbi, magetsi uye mamwe maindasitiri minda.
3. Kuisa chisimbiso
- Mavharuvhu eshavishavi akapfava anotsamira pazvigaro zvevharuvhu zvakaita serabha kana PTFE kugadzira chisimbiso nekudzvanya padivi pevharuvhu.Pane imwe mukana wekuti chisimbiso ichi chinodzikisira nekufamba kwenguva, zvichigona kukonzera kuvuza.
- Mavharuvhu ebhora anowanzo kuve nesimbi-ku-metal kana zvisimbiso zvakapfava zvechigaro zvinopa chisimbiso chakavimbika kunyangwe mushure mekushandisa kwenguva refu.
Muchidimbu, mavharuvhu eshavishavi uye mavharuvhu ebhora chimwe nechimwe chine zvakanakira uye zvazvakaipira, uye ndeipi vharafu yekusarudza zvinoenderana nemamiriro ekushandisa uye zvinodiwa.
ZFA Valve Company ifekitari ine hunyanzvi mukugadzira mavharuvhu akasiyana siyana.Kana uine mibvunzo, tapota inzwa wakasununguka kutibata nesu.
