Ungasarudza sei Stainless simbi wafer cheki valve?

Stainless simbi wafer cheki vharafu ivharuvhu otomatiki ine mhando dzakawanda uye zvakatemwa.Mhando iyi yechigadzirwa inonyanya kushandiswa kudzivirira kuyerera kwepakati, kutenderera kutenderedza kwepombi uye mota yayo yekutyaira, uye kuburitswa kwepakati mumudziyo.Inogona kushandiswa kune zvakasiyana-siyana pamutsara wepakati.Saka isu tinosarudza sei simbi isina tsvina yewafer cheki valve?Chii chinofanira kucherechedzwa?

1. Zvinowanzokurudzirwa kuti vashandisi vasarudze simbi yakaoma-yakavharwa mavharuvhu ekutarisa mavharuvhu kuti vaone kuti wafer cheki mavharuvhu ane hupenyu hwesevhisi hurefu, tembiricha yekushanda yakakwirira, uye yakafanana yakanaka yekuisa chisimbiso kuita.

2. Kana saizi yezita yakakura kupfuura kana yakaenzana neDN100 (NPS4), zvinokurudzirwa kusarudzaH76 mhando mbiri disc swing wafer cheki vharafu, iyo inogona kubudirira kuderedza kurasikirwa kwemvura inopikisa yevhavha yekuongorora;saizi yezita ishoma pane kana yakaenzana neDN80 (NPS3), uye sarudzo H71 mhando yekusimudza cheki valve yakakodzera.

3. TheH71 kusimudza mhando wafer cheki vharafuine saizi yezita isingasviki kana kuenzana neDN100 (NPS) haiwanzo kugadzirwa nekuda kweiyo compact chimiro uye tichifunga nezvekugadzirisa uye kugadzira.Zvinokurudzirwa kuti vashandisi vasarudze Stainless simbi yekusimudza mhando wafer cheki mavharuvhu.vharafu.

4. Pamusoro pemhando yewafer, simbi isina tsvina kaviri disc swing check valve inewo lug type uye flange type.Kana mushandisi asina zvakakosha zvinodikanwa, fomu rezvimiro rinowanzo gadzirwa nekambani yedu zvinoenderana neyakajairwa zviyero.Mamwe kaviri disc swing cheki mavharuvhu anogona kugadzirwa ane kaviri flange chimiro (mhando H46).

5. Iyo lug flange ye lug double flap swing check valve inongotora basa rekuisa, uye bhegi haritakuri simba rebhoti, saka ukobvu hwebhegi flange hauna kugadzirwa zvichienderana nekukora kweiyo standard flange, kazhinji. the lug flange Ukobvu hushoma pane hwemaflanges akajairwa.Iyo flange yekaviri flange yekubatanidza kaviri disc swing cheki vharafu inotakura bhaudhi simba, uye iyo flange ukobvu inogadzirwa zvinoenderana neyakajairwa flange.

6. Iyo yekusimudza-mhando yewafer cheki mavharuvhu ane mazita ekumanikidza PN10, PN16, PN25 uye PN40 ane maviri eurefu hwemaitiro akateedzana.Mutengo wemapfupi akateedzana cheki mavharuvhu wakaderera, asi asiri-standard ekubatanidza gaskets anogona kudiwa pakati pecheki vharafu uye pombi flange.Kana yakareba yakatevedzana cheki mavharuvhu akashandiswa, akajairwa flange gaskets anogona kugadzirwa.
