PQ divi rakaiswa nzira mbiri dzakavharwa eccentric hemisphere valve

Tsanangudzo Pfupi

PQ divi rakaiswa maviri-nzira chisimbiso eccentric hemisphere valve inogadzirwa pahwaro hwekutora clip mhando kuyerera kukuru kuburikidza nevharuvhu inogadzirwa neCANALI kambani yekuGermany. Chimiro chayo chinotora musimboti we eccentric clamping, uye inozadzisa chinangwa chevhavha kuomesa, kugadzirisa uye kuvhara kuburikidza nenzira yekufambisa. The seal pair isimbi yekumeso mhete ine hard face seal contact. Iyo yakapetwa kaviri eccentric chimiro chiri muvhu rakavhurika revhavha rinowanikwa mukamuri yebhora, uye chikamu chekuyerera idiki Kana vharuvhu ichivhurwa, pamusoro pevhavha core zvishoma nezvishoma padivi pechigaro chevhavha, iyo inogona kunyatsobvisa zvipingamupinyi zvekuyera uye kubudirira. kuiswa chisimbiso kwakavimbika. Chinhu chekutanga ndechekuti inonyanya kushanda kune yakasanganiswa kuyerera kwekufambisa kwezvikamu zviviri zvakasanganiswa kuyerera zviri nyore kuyera mvura yakasimba; chechipiri chimiro ndechekuti hemisphere yevhavha yakafukidzwa neyakasiyana alloys pane bimetal uye base simbi, uye chigaro chevharuvhu chakafukidzwawo neinowirirana alloy. Mushure mekurapa kwakakosha, boka rekuisa chisimbiso rinoumbwa nemhando dzakasiyana-siyana dzakadai se-anti-corrosion, kupfeka kusagadzikana, simba rakakwirira, nezvimwewo, kusangana nezvinodiwa zvezviitiko zvakasiyana; chinhu chechitatu ndechekuti chisimbiso chakasimba, uye kutakurwa kwemagasi anokuvadza kunogona kusvika pachiyero Hapana kubuda; chinhu chechina ndechekuti vharafu yevhavha yevhavha yekuisa chisimbiso ine muripo. Kana chigaro chevhavha chakapfekwa, chinogona kuramba chakavharwa zvakavimbika uye hupenyu hwebasa hunogona kurebeswa nekutendeuka zvishoma kana yakavharwa. Mukuwedzera, iyo compression nut inogona kushandiswa mushure mekuputirwa, kugadziriswa kana kutsiviwa nemushandisi, izvo zvinodzivirira kukanganisa kwevakawanda varipo vevhavha chisimbiso kukundikana uye yakazara seti scrapping. Naizvozvo, kusarudzwa kwekutarisa kwakasiyana alloy bimetallic seal pairs inogona kushandiswa munzvimbo dzakasiyana dzemaindasitiri dzinoda kuiswa chisimbiso chakasimba, senge kupfeka kuramba, corrosion resistance, high tembiricha kuramba, nezvimwe.

Product features

1. Nzvimbo yakakura yekutenderera uye kushomeka kudiki kuyerera. Izvi zvinodaro nekuti iyo yekuvhura valve core inowanikwa mukamuri yebhora, uye mvura inopfuura

2. Diki rekushandisa torque, shandura 90 madhigirii kuvhura uye kuvhara, nyore kushanda

3. Chisimbiso chakasimba; kaviri eccentric simbi yakaoma chisimbiso. Chimiro hachikanganisa kuvhura nekuvhara, iyo inonyanya kukosha yehemisphere valve

4. Hupenyu hurefu hwebasa, kupfeka-kusavhara chisimbiso peya, nemubhadharo, chigaro chevharuvhu chinogona kugadziridzwa kana kutsiviwa.
