Izindaba Zezimboni

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.

I-Butterfly valve uhlobo lwe-valve olusebenzisa uhlobo lwe-disc evulayo kanye nento yokuvala ukushintshanisa emuva naphambili cishe ngama-90 degrees ukuvula, ukuvala, noma ukulawula isilinganiso sokugeleza okuphakathi. Ama-butterfly ama-valve awagcini nje ngokuba nesakhiwo esilula, isisindo esincane, isisindo esikhanyayo, ukusetshenziswa okuphansi okubonakalayo, usayizi omncane wokufaka, i-torque ephansi, ijubane elisheshayo, futhi futhi linomsebenzi omuhle wokulawula ukugeleza kanye nokuvalwa kwezimpawu zokugcina uphawu.

Ama-valves webhola aqashwe kabanzi ezinhlelweni zamapayipi ezimboni wanamuhla ngenxa yezinhlelo zawo eziningi ezahlukahlukene, ukusebenza okuphezulu kokubekwa uphawu, kanye nokusebenza kalula.

Ezitshalweni zamandla, amapayipi kawoyela kanye negesi, amasistimu wamanzi, kanye neminye imisebenzi yezimboni, ama-valves wesango angumbala wokulawula ukugeleza okuthe xaxa.
