產(chǎn)品用途
BZ41H、BZ41W、BZ41Y 型 PN16~PN40 保溫夾套式楔式閘閥：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)結晶，以輸送常溫下會凝固的高粘度介質(zhì)。
產(chǎn)品特點
①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。
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，結構長度與同規(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。
