A216 WCB Kanda Steel Trunnion Yakakwira Bhora Valve

Chikamu chechigaro cheiyo yakagadziriswa bhora vharafu ine self tightening maitiro, ayo anogona kuzadzisa kuvharika kwekukwira. Zvigaro zvese zviri zviviri zvevhavha zvinogona kuiswa chisimbiso, saka hapana chinorambidzwa kuyerera panguva yekuiswa uye iri bidirectional.

Kune marudzi maviri evharuvhu emuviri zvimiro zveyakagadziriswa bhora mavharuvhu: maviri chidimbu uye matatu chidimbu. Iyo flange yepakati yakabatana nemabhaudhi, uye chisimbiso chinogadzirwa neyakasimbiswa polytetrafluoroethylene yakamisikidzwa mumhete yesimbi. Kune chitubu kuseri kwemhete yesimbi kuve nechokwadi chekuti chigaro chevharuvhu chakanyatso kutarisana nebhora, kuchengetedza chisimbiso. Ese ari maviri epamusoro uye epasi mavharuvhu madzinde akashongedzerwa nePTFE mabheji ekudzikisa kukweshera uye kuchengetedza kushanda. Pazasi peiyo shaft diki yakashongedzerwa mahwendefa ekugadzirisa kuti ive nechokwadi chekumira kwebhora uye chisimbiso mhete pajoini. Full bore: The valve flow aperture inoenderana nemukati dhayamita yepombi yekuchenesa pombi.

Performance mabhenefiti eakakanda simbi trunnion akaiswa bhora mavharuvhu kubva kuBOLON.

1.Low torque kushanda

Iyo sphere inotsigirwa nepamusoro uye yakaderera mabhengi, kuderedza kukweshera uye kubvisa yakawandisa torque yakakonzerwa nemutoro muhombe wekuisa chisimbiso wakagadzirwa neiyo inlet pressure inosunda sphere uye chigaro chekuisa chisimbiso.

2.Kuvimbika kwekuisa chisimbiso kuita

Iyo PTFE single material sealing ring yakaiswa mustainless steel valve seat, uye chitubu chinoiswa kumagumo kwechigaro chesimbi chevharuvhu kuti ive nechokwadi chakakwana chekusimbisa simba remhete yekuisa chisimbiso. Kana iyo yekuisa chisimbiso pamusoro pevhavha yakapfekwa panguva yekushandiswa, iyo valve inoramba iine chokwadi chekuisa chisimbiso kushanda pasi pechiito chechirimo.

3.Chimiro chisina moto

Kuti udzivise kuitika kwekupisa kamwe kamwe kana moto, izvo zvinogona kuita kuti PTFE yekuvhara mhete inopisa uye inokonzera kubuda kukuru, uye kukurudzira moto, mhete yekuvhara moto inoiswa pakati pe sphere nechigaro chevhavha. Kana mhete yekuisa chisimbiso ichipiswa kunze, pasi pekuita kwesimba rechirimo, rin'i yekuisa chisimbiso yevharuvhu inokurumidza kusundirwa padenderedzwa, ichigadzira simbi kune chisimbiso chesimbi uye kuwana imwe dhigirii yekuisa chisimbiso. Muedzo wekupikisa moto unosangana nezvinodiwa zveAPl6FA uye APl607 zviyero.

4.Automatic pressure relief function

Kana dzvinyiriro yesvikiro inomira mukamuri yevharuvhu ichiwedzera zvisina kujairika kupfuura simba rekutanga rechirimo, chigaro chevharuvhu chinodzora nekubvarura kubva padenderedzwa, zvichiwana mhedzisiro yekudzikinura otomatiki. Mushure mekudzvinyirirwa, chigaro chevharuvhu chinongopora

5.Basa rekuchenesa mapaipi

Maburi emvura anoiswa pamativi ese emuviri wevharuvhu kuti atarise kuti pane kubuda muchigaro chevharuvhu. Panguva yekushanda, kana valve yakazaruka zvakakwana kana yakavharwa zvakakwana, kumanikidzwa mukati mekamuri yepakati kunogona kubviswa uye kutakura kunogona kuchinjwa zvakananga; Inogona kuburitsa zvakasara mukati mekamuri yepakati uye kuderedza kusvibiswa kwepakati pavharuvhu.

6.Kuvhara emergency girisi jekiseni kununura

Nekuda kwezvinhu zvekune dzimwe nyika mukati kana moto zvichikonzera kutadza kwetsaona kwevharuvhu chisimbiso chechigaro chevharuvhu, vharafu yegirisi inopa kukurumidza kubatana nepfuti yegirisi, uye pombi inotengeswa kunze kwenyika zviri nyore uye nekukurumidza inopinza chisimbiso girisi munzvimbo yekuvharisa chigaro chevharuvhu kuti ideredze kubuda.

7.Yakavimbika valve stem seal uye yakaderera inoshanda torque

Pamusoro pekuisa zvindori zvekuvhara zvakajairwa, zvisimbiso zveO-ring zvinoiswawo pane packing gland, kuve nechokwadi chekuvimbika kwevhavha stem seal ine chisimbiso cheviri; Kuwedzerwa kwegraphite kurongedza uye kuvhara jekiseni regirisi kunoderedza kubuda kwevharuvhu mushure memoto. Mabhengi anotsvedza uye mabearings ekusundira ehunde yevharuvhu anoita kuti kushanda kwevhavha kuve nyore.

8.Bore rakazara kana rakaderedzwa bore

Zvimiro zvakazara kana zvakaderedzwa zvibodzwa zvinogona kusarudzwa sezvinodiwa. Kuyerera kwevharuvhu yakazara inopindirana nedhayamita yemukati yepombi, zvichiita kuti zvive nyore kuchenesa pombi.

9.Ivhavha hunde inogona kuwedzerwa

Zvinoenderana nekuisa kana kushanda zvinodiwa, iyo valve stem inogona kuwedzerwa. Yakawedzerwa tsvimbo bhora vharafu, kunyanya yakakodzera gasi remudhorobha uye zvimwe zviitiko zvinoda kuvigwa pombi yekuisa. Saizi yehunde yevharuvhu yakawedzerwa ichatarwa zvichienderana nezvinodiwa nevatengi.

10.Flexible operation

Kushandiswa kwechigaro uye stem mabhengi ane diki friction coefficient uye yakanaka self-lubricating properties inoderedza zvakanyanya torque yekushandisa yevhavha. Nokudaro, kunyange pasina kupa chisimbiso girisi, vharuvhu inogona kushandiswa flexibly uye vakasununguka kwenguva refu.
