進口高溫高壓針型閥產(chǎn)品描述:Description of imported high temperature and high pressure needle valve:
進口高溫高壓針型閥是一種微調閥,其閥塞為針形,主要用作調節(jié)氣流量。微調閥要求閥口開啟逐漸變大,從關閉到開啟zui大能連續(xù)細微地調節(jié)。針形閥塞即能實現(xiàn)這種功能。針形閥塞一般用經(jīng)過淬火的鋼制長針,而閥座是用錫、銅等軟質材料制成。閥針與閥座間的密封是依靠其錐面緊密配合達到的。閥針的錐度有1:50和60錐角兩種,錐表面要經(jīng)過精細研磨。閥桿與閥座間的密封是靠波紋管實現(xiàn)的。美國泰樂TYLER進口散熱式高溫高壓針型閥有對焊或插焊安裝,連接緊固,具有受壓大、嚴密的密封性能、超長的使用壽命,通常用在較小流量,較高壓力的氣體或者液體介質的密封。
進口高溫高壓針型閥應用范圍-Application range of imported high temperature and high pressure needle valve
進口散熱式高溫高壓針型閥適用于電力、石化、熱油、鍋爐等較高壓力的氣體或者液體介質的密封,與壓力表配合使用,是儀表測量管路系統(tǒng)中作開啟或切斷管路作用。
