Kev lag luam xov xwm

Fluid temperature: High temperature fluids (above 450 ℃) should choose high-temperature resistant valves, such as chromium molybdenum steel high-temperature gate valves used in steam pipelines. Low temperature fluids (below -40 ℃) require valves with good low-temperature toughness, and low-temperature ball valves are commonly used in liquid nitrogen and liquid oxygen pipelines.

Npauj Npaim Valve yog ib hom kev siv valve uas siv ib hom disc qhib thiab tawm mus qhib, kaw kom haum ntawm qhov nruab nrab. Npauj npaim li qub tsis tsuas yog muaj cov qauv yooj yim, qhov hnyav me, kev ua haujlwm me me, tab sis kuj tseem muaj cov dej ntws yooj yim, tab sis kuj tseem muaj cov cwj pwm txaus thiab kaw cov yam ntxwv sealing.

Pob li qub yog siv tau dav hauv cov twj siv hluav taws xob niaj hnub vim yog lawv cov kev siv ntau yam, zoo dua kev ua haujlwm, thiab yooj yim ntawm kev ua haujlwm.

Hauv cov hluav taws xob cov ntoo, roj thiab roj tshuab, cov tshuab dej, thiab lwm yam kev lag luam, cov khoom sib tw yog qhov tseem ceeb heev tswj tswj cov khoom siv.
