PQ divi rakaiswa nzira mbiri dzakavharwa eccentric hemisphere valve

Tsanangudzo Pfupi

PQ divi rakaiswa bi-directional eccentric hemisphere valve inogadzirwa pahwaro hwekutora uye kugaya iyo mbiri clip mhando huru inoyerera nevharuvhu (maxiflu stell ventile) inogadzirwa neCanal kambani yekuGermany. Chimiro chayo chinotora iyo eccentric clamping musimboti kuzadzisa chinangwa chekuvhara, kugadzirisa uye kuvhara kuburikidza neyekufambisa nzira. Iyo yekuisa chisimbiso isimbi yakatarisana nemhete ine chisimbiso chakaoma chekubata kumeso, uye iyo yevhavha yepakati yekaviri eccentric chimiro inowanikwa munzvimbo yakavanzika kana ichivhurwa Mukamuri yebhora, chikamu chekuyerera chakakura, uye vharafu haina kucheneswa. . Kana vharuvhu yakavharwa, simbi yevhavha haina kucheneswa. Kana vharuvhu yakavhurwa, iyo spherical pamusoro peiyo valve core inofamba asymptotically ichitevedza chigaro chevharuvhu, iyo inonyatso bvisa zvipingamupinyi zvekuyera uye inoona 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 inogadzirwa nebimetallic, simbi yepasi yakafukidzwa neakasiyana alloys, chigaro chevharuvhu chakafukidzwawo nechakatarisana, uye nzvimbo yekuisa chisimbiso inounganidzwa nemhando dzakasiyana dzeanti-corrosion, kupfeka- kusagadzikana, kusimba kwepamusoro, nezvimwewo, kusangana nezvinodiwa zvezviitiko zvakasiyana; Chechitatu chisimbiso chisimbiso, kuendesa gasi rinokuvadza rinogona kusvika zero leakage; chinhu chechina ndechekuti chivharo chevhavha yevhavha yekuisa chisimbiso chine muripo, kana chigaro chevhavha chakapfekwa (kuoma kwechigaro chevhavha yakaderera pane iyo yepakati yevhavha), kana yakavharwa, inogona kuramba yakavharwa uye yakavimbika. hupenyu hwebasa hunowedzerwa. Mukuwedzera, chigaro chevharuvhu chinogona kushandiswa mushure mekugadzirisa kana kutsiva nekuputira nut yekumanikidza, iyo inodzivirira kukanganisa kuti kuiswa chisimbiso kwemavharuvhu mazhinji aripo haashande uye vheji yese inoputswa. Naizvozvo, kusarudzwa kweakasiyana alloy (kana musanganiswa bhora) bimetallic sealing pairs inogona kushandiswa munzvimbo dzakasiyana dzemaindasitiri, senge kupfeka kusagadzikana, kushomeka kwekupokana, kupisa kwekushisa kwakanyanya uye kuiswa chisimbiso kwakasimba.

Kushandiswa kwePQdivi rakaiswa nzira mbiri dzakavharwa eccentric hemisphere valve

Inokodzera kuchenesa tsvina, pulp, alumina, kupisa kwemadhorobha, petrochemical, gasi, slurry, marasha madota, nezvimwe.

Product features

1. Nzvimbo yakakura yekutenderera uye kushomeka kudiki kuyerera. Izvi zvinodaro nekuti mushure mekuvhura, iyo yevhavha yepakati inowanikwa mukamuri yebhora, uye mvura yakatwasuka.

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. Upenyu hurefu hwebasa, kupfeka-resistant sealing pair, nekubhadhara, chigaro chevhavha chinogona kugadziriswa kana kuchinjwa.
