BZ41H、BZ41W、BZ41Y 型 PN16~PN40 保溫夾套式閘閥:手動、法蘭連接、明桿楔式剛性單閘板,閥座密封面材料為合金和不銹鋼,公稱壓力 PN16~PN40,閥體材料為碳鋼(BZ41H-16C~BZ41H-40 BZ41Y-16C~BZ41Y-40)、鉻鎳鈦不銹鋼(BZ41W-16P~BZ41W-40P BZ41Y-16P~BZ41Y-40P)、鉻鎳鉬鈦不銹鋼(BZ41W-16R~BZ41W-40R BZ41Y-16R~BZ41Y-40R),具有保溫功能的閘閥。主要用于石油、化工、冶金、制藥等各類系統(tǒng)中,能保溫和防止介質(zhì)結(jié)晶,以輸送常溫下會凝固的高粘度介質(zhì)。
保溫夾套式閘閥產(chǎn)品特點
①夾套焊裝于閥門的兩法蘭之間,閥門的側(cè)面、底部設置有夾套的連接口。②連接法蘭尺寸比同一規(guī)格普通閥門的連接法蘭大一到兩個規(guī)格,結(jié)構(gòu)長度與同規(guī)格的普通閥門相同。③夾套中可自由地流過蒸汽或其它熱的保溫介質(zhì),確保粘稠介質(zhì)可順暢地流過閥門。
