Pane here zvinodiwa pakugadzwa kwemavharuvhu eshavishavi?

Iyo yekuisa nzira yebutterfly valves inofanira kutariswa maererano nemhando yavo uye mamiriro ekushanda. Bidirectional sealed butterfly mavharuvhu kazhinji haave nekwakaoma kwainodiwa, asi kune inokurudzirwa yekuisa nzira; Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha nzira yekuiswa kwainotarwa.

Butterfly mavharuvhu akakamurwa kuita mhando mbiri: bidirectional sealing uye unidirectional chisimbiso. For bidirectional yakavharwabutterfly mavharuvhu, ne theoretically hapana zvirambidzo zvakaomesesa zvekumisikidza, asi pane zvinokurudzirwa kumisikidza mafambiro mukuita engineering. Semuyenzaniso, mupombi yakatwasuka, gwara revharuvhu hunde rinogona kusarudzwa muhurongwa hwekudzika kumusoro, kuchinjika, uye 45 ° kuenda kumusoro. Iyi nzira yekuisa iri nyore kushanda uye inogona kuve nechokwadi chekufanana kwechisimbiso. Pamavharuvhu eshavishavi mahombe-dhayamita (akadai seDN500 zvichikwira), zvinokurudzirwa kuisa muviri wevharuvhu wakachinjika uye chinobatisa chiri pamusoro kuti usakanganiswa nehuremu hwendiro yevharuvhu pa torque. Kana pombi yepakati iine tsvina (yakaita sedhaka, jecha, nemvura), zvinokurudzirwa kuti kuyerera kwepakati kupinde kubva kumashure kwevharuvhu yeplate yekuvharisa kuti kuderedze kusakara uye kuwedzera hupenyu hwevharuvhu.

Kuiswa kweimwe-nzira yakavharwabutterfly mavharuvhuine nhungamiro yakajeka inodiwa. Muviri wevharuvhu unowanzo kucherechedzwa nearrow markings, uye kwainoenda museve kunofanirwa kuenderana nekuyerera kwepakati mupombi panguva yekuisa, zvikasadaro inogona kukonzera kutadza chisimbiso kana kudonha kwepakati.

Mavharuvhu eshavishavi ari maviri akananga uye akasarudzika haabvumidzwe kuiswa zvakadzika zvichidzika munzira yehunde yevharuvhu. Kana dzinde revharuvhu rakatarisa pasi, pombi yepakati inogona kudonha kubva pahunde yevharuvhu, kunyanya kana ichitakura acidic, alkaline, uye huturu media, izvo zvinoisa njodzi kuchengetedzeka kwevashandisi. Mukuwedzera, kuisa tsinde yevhavha pasi pasi kuchawedzera kuoma kwekushanda, zvinoda kuti mufambisi asimudze musoro wavo kuti ashande, izvo zvisingaenderani ne ergonomic design.

Nzvimbo yekuisa ye butterfly valves inofanira kunge iri nyore kushanda. Mubato kana vhiri reruoko remavharuvhu ebhurawuza rinowanzoita 1.2 metres kubva pauriri hwekushanda, kusvika panzvimbo yechipfuva, izvo zvinoita kuti kuvhura nekuvhara kusashande. Kana vharuvhu yakaiswa pasi, handwheel kana mubato unofanira kutarisana kumusoro uye kwete kurereka; Kana yaiswa pamadziro kana midziyo, siyai nzvimbo yakamira kune vanoishandisa kudzivirira kushanda kubva kudenga.
