Chii chinonzi globe valve?
Nzvimbo dzekuvhura nekuvhara dzevhavhavhavhavhavhavhavhavhavhadhidhidhidhidhidhidhidhidhidhi,iyo yekuisa chisimbiso yakati sandara kana conical, uye dhisiki inofamba mumutsara wakatwasuka uchitevedza mutsara wepakati wemvura.Mafomu ekufambisa stem, kune mhando yekusimudza tsvimbo (kusimudza tsinde, handwheel isiri kusimudza), kune inosimudza rotary tsvimbo yemhando (handwheel uye dzinde rinotenderera richisimudza pamwechete, nati mumuviri wevharuvhu).Globe valve inokodzera chete kuvhurika kwakazara uye kuvharika kwakazara, kusatenderwa kugadzirisa uye kupuruzira.
Globe mavharuvhu anomanikidzwa akavharwa mavharuvhu, saka kana vharuvhu yakavharwa, kudzvanywa kunofanirwa kuiswa kune disc kumanikidza kuvharika kwechiso hakubvire.Kana iyo yepakati kubva pasi pe disc ichipinda muvharuvhu yechitanhatu, kuramba kukunda simba rekushanda isimba rekukwesha kwehunde uye kurongedza uye kusunda kunogadzirwa nekumanikidza kwepakati, simba rekuvhara vharuvhu rakakura kupfuura simba. yekuvhura vharuvhu, saka dhayamita yetsinde inofanira kunge yakakura, kana zvisina kudaro kutadza kweiyo stem top bending kuchaitika.Mumakore achangopfuura, kubva pakubuda kwevhavha yekuisa chisimbiso, kuyerera kwepakati yevhavhavhavha inoshandurwa kubva kumusoro kwevhavha kuenda mukamuri yevharuvhu, zvino pasi pekuita kwepakati pressure, simba rekuvhara vharuvhu iri. diki, uye simba rekuvhura valve rakakura, uye dhayamita yetsinde inogona kuderedzwa zvinoenderana.Panguva imwecheteyo, pasi pekuita kwepakati, iyi fomu yevhavha inowedzerawo kuoma.Varuvhu yeChina yakataura kuti kuyerera kwevharuvhu kuri pamusoro-pasi.
Kana iyo globe valve yakavhurwa, kureba kwekuvhura kwevhavha disc ndeye 25% kusvika 30% yezita rezita, uye kuyerera kwasvika pakakwirira, zvichiratidza kuti valve yasvika pazere nzvimbo yakazaruka.Nokudaro, nzvimbo yakazara yakazaruka yevhavha yepasi inofanira kugadziriswa nekurohwa kwevhavha disc.
Globe vharafu inogona kupatsanurwa kuita: globe vharafu, threaded stem globe valve, threaded stem globe valve, yakatwasuka-kuburikidza neglobe vharafu, Angle globe vharafu, nzira nhatu dzeglobe vharafu, yakatwasuka-inoyerera globe vharafu, plunger globe vharafu, tsono yeglobe vharafu.
Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
