BH44H/W夾套保溫止回閥主要用于石油、化工、冶金、制藥等各類系統中，以輸送常德下會凝固的高粘度介質。該系列閥門的夾套焊裝于閥門的兩法蘭之間，閥門的側面、底部設置有夾套的連接口。由于增加了夾套，此種閥門的連接法蘭尺寸要比同一規格普通閥門的連接法蘭大一到兩個規格，但結構長度與同規格的閥門相同，夾套中可自由地流過蒸汽或其它熱的保溫介質，確保粘稠介質可順暢地流過閥門。夾套保溫止回閥要外形尺寸 GB 1.6MPaDN1520253240506580100125150200250300L130150160180200230290310350400480600650750H9095100105110115140170200230255285290300Wt1415161718192429405883100105110   GB 2.5MPaDN1520253240506580100125150200250300L130150160180200230290310350400480600650750H9095100105110115140170200230260285290300Wt14151617181924294072104145180230GB 4.0MPaDN3240506580100125150200250300L180200230290310350400480600650750H120140150160175200225260315320300Wt9121520334173104147180230GB 6.4MPaDN3240506580100125150200250300L230260300340380430500550600775900H160170170190205230265310350480520Wt122029354768100142195250300   GB10.0MPaDN1520253240506580100125150200250300L130150160180200230290310350400480600650750H9095100105110115140170200230255285290300Wt1415161718192429405883100105110GB 16.0MPaDN1520253240506580100125150200250300L130150160180200230290310350400480600650750H9095100105110115140170200230260290290300Wt14151617181924294072104180180230BH44W夾套保溫止回閥_圣核閥門制造（上海）有限公司
