Txoj moo

Raws li cov cuab yeej tseem ceeb rau kev tswj cov kua, cov kev sib tw hauv kev lag luam tseem ceeb hauv kev lag luam sib txawv tau ua rau kev loj hlob sib txawv ntawm cov rooj vag li qub.

Los ntawm cov kev pom ntawm kev ua lag luam loj, lub ntiaj teb npauj npaim valve ua lag luam, tsav los ntawm kev hloov kho tshiab, thiab kev lag luam nrawm nrawm nyob rau hauv cov khoom lag luam tawm tshiab.

Txhim kho cov sealing kev ua tau zoo ntawm cov npauj npaim li yuav tsum tau txhim kho hauv kev tsim, cov ntaub ntawv, kev teeb tsa, thiab lwm yam

Kev xaiv ntawm cov ntaub ntawv sealing rau npauj npaim yuav tsum muaj kev txiav txim siab ntawm ntau yam. Tsuas yog xaiv cov khoom zoo puas tuaj yeem tuav cov khoom zoo li cas kom muaj kev sib luag hauv ntau yam haujlwm ntawm cov kab ke.

Pob li qub tau dhau los ua cov kua dej tsis muaj kua tswj cov khoom siv hauv kev lag luam thiab pej xeem vim lawv cov kev xav tau zoo meej.

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.
