BH41W夾套保溫止回閥概述：

保溫夾套止回閥主要用于石油、化工、冶金、制藥等各類系統(tǒng)中，以輸送常溫下會凝固的高粘度介質(zhì)。保溫系列閥門的夾套焊裝于閥門的兩法蘭之間，閥門的側(cè)面、底部設(shè)置有夾套的連接口。由于增加了夾套，保溫閥門的連接法蘭尺寸要比同一規(guī)格普通球閥的連接法蘭大一到兩個(gè)規(guī)格，但結(jié)構(gòu)長度與同規(guī)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(zhì)，確保粘稠介質(zhì)可順暢地流過閥門。

應(yīng)用范圍：
保溫止回閥主要用于石油、化工、冶金、制藥等各類系統(tǒng)中，以輸送常溫下會凝固的高粘度介質(zhì)。

結(jié)構(gòu)特點(diǎn)：
保溫止回閥的主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機(jī)反轉(zhuǎn)
