     常見的液位計(jì)根部的閥是用于設(shè)備與測(cè)量系統(tǒng)的分割,就是個(gè)連接或斷開設(shè)備與測(cè)量系統(tǒng)的開關(guān),由于它的位置處于設(shè)備和測(cè)量系統(tǒng)的起始處,所以都稱為它“根部閥”
根部閥在實(shí)際的理論上可以在任意結(jié)構(gòu)的閥門都是實(shí)用的,在實(shí)際選用時(shí)可以不與介質(zhì)發(fā)生反應(yīng),動(dòng)作不受介質(zhì)影響,比較容易密封,比較不容易堵塞,少維護(hù)作為選用要求。另外在不同行業(yè)的標(biāo)準(zhǔn),設(shè)計(jì)規(guī)范都有需要根據(jù)行業(yè)特點(diǎn)的應(yīng)用習(xí)慣而定!
