Sechikamu chakakosha cheiyo maindasitiri system, kuisirwa kwayo kwakakosha.Ivhavha yakanyatsogadziriswa haingoiti chete kuti iite kuyerera kwemvura yehurongwa, asiwo inochengetedza kuchengeteka uye kuvimbika kwekushanda kwehurongwa.Munzvimbo dzakakura dzeindasitiri, kuiswa kwemavharuvhu hakudi kungotariswa kwehunyanzvi ruzivo, asiwo kutevedzera zvinoenderana nemitemo yekuchengetedza uye zviyero.Nokudaro, kukosha kwekugadzirisa kwakarurama kwevhavha hakungoratidzi mukubudirira uye kugadzikana kwekushanda kwehurongwa, asiwo mukuchengetedzwa kwevashandi nemidziyo.Kuburikidza nekumisikidza kwakaringana, matambudziko ekudonha anogona kuderedzwa, kushanda zvakanaka kwehurongwa kunogona kuvandudzwa, tsaona dzemaindasitiri dzinogona kudzivirirwa, nharaunda nehupenyu hwevashandi uye zvivakwa zvinogona kuchengetedzwa, nekudaro zvichipa dziviriro yakavimbika yekugadzirwa kwemaindasitiri.Naizvozvo, kuisirwa kwakaringana kwemavharuvhu kwakakosha uye ndeimwe yezvisungo zvakakosha mukuona kushanda kwakachengeteka kwemaindasitiri masisitimu.

1.Inverted valve.

Migumisiro: valve inverted, throttle valve, pressure kuderedza valve, cheki valve uye mamwe mavharuvhu anotungamira, kana inverted inverted, throttle ichakanganisa kushandiswa kwekushandisa uye hupenyu;Mavharuvhu ekudzikisa mavharuvhu haashande zvachose, uye mavharuvhu ekutarisa anogona kutounza njodzi.

Zviyero: Mavharuvhu akazara, ane zviratidzo zvinotungamira pamutumbi wevharuvhu;Kana zvisina kudaro, inofanira kunyatsozivikanwa maererano nemutemo wekushanda wevhavha.Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharika asymmetrical,uye mvura inonaya inofanira kubvumidzwa kupfuura nepachiteshi chevharuvhu kubva pasi ichienda kumusoro, kuitira kuti mvura inodzivirirwa idiki (yakatemerwa nechimiro), kuvhura ndiko kuchengetedza basa (nekuda kwe kumanikidzwa kwepakati kumusoro), uye yepakati haitsikidzi kurongedza mushure mekuvhara, izvo zviri nyore kugadzirisa.Ichi ndicho chikonzero valve yekumira haigoni kuchinjwa.Usapinze vharafu yegedhi (kureva, vhiri reruoko pasi), zvikasadaro svikiro icharamba iri munzvimbo yevhavha yevhavha kwenguva yakareba, iri nyore kuodza hunde yevharuvhu, uye inorambidzwa kune mamwe maitiro ekuita.Izvo zvakanyanya kusagadzikana kushandura kurongedza panguva imwe chete.Vhura stem gedhi vharafu, usaise muvhu, zvikasadaro nekuda kwehunyoro uye ngura yakafumurwa vharafu.Simudza cheki vharafu, kuisirwa kuve nechokwadi kuti vharafu disc vertical, kuitira kuti kusimudza kuchinjike.Swing cheki vharafu, kuisirwa kuve nechokwadi kuti iyo pini nhanho, kuitira kuti iite inoshanduka.Ivhavha yekudzikisa kumanikidza inofanira kuiswa yakatwasuka papombi yakatwasuka, uye usarerekera kune chero nzira.

2.Kuiswa kweValve kusati kwaitwa kuongororwa kwehutano hunodiwa.

Mhedzisiro: Inogona kutungamirira kuhurongwa hwekushanda kwevhavhavha haichinjiki, yakavharwa zvakasununguka uye kubuda kwemvura (gasi) chiitiko, zvichiita kuti pave nekugadzirisa, uye kunyange kukanganisa mvura yakajairika (gasi).

Matanho: Pamberi pekuiswa kwevharuvhu, kumanikidza simba uye tightness bvunzo inofanira kuitwa.Muedzo uchaitwa nesampling 10% yehuwandu hwebatch yega yega (giredhi rimwechete, kutsanangurwa kwakafanana, modhi yakafanana), uye isiri pasi peimwe.Kune mavharuvhu akavharwa edunhu akaiswa papombi huru iyo inotamba basa rekucheka, simba uye tightness miedzo inofanira kuitwa imwe neimwe.Simba revhavha uye tightness bvunzo kumanikidza kunoenderana nemhando yekugamuchira kodhi.

3.Butterfly valve flange ine yakajairika valve flange.

Mhedzisiro: saizi yevharuvhu flange yakasiyana neiyo yeyakajairika valve flange.Mamwe maflange ane madhayamita madiki emukati, uye butterfly valve flap yakakura, zvichikonzera kutadza kuvhura kana kuvhura zvakasimba vharafu.

Zviyero: Flange inofanira kugadziriswa maererano nehukuru chaihwo hwevhavhavhavhavhavha flange.
