burkert3234型手動零死區(qū)T形膜片閥,德國burkert手動閥,寶德氣動膜片閥
burkert3234型手動零死區(qū)T形膜片閥用在受壓設(shè)備、容器或管路上，作為超壓保護裝置。當(dāng)設(shè)備、容器或管路內(nèi)的壓力升高超過允許值時，閥門自動開啟，繼而全量排放，以防止設(shè)備、容器或管路內(nèi)的壓力繼續(xù)升高；當(dāng)壓力降低到規(guī)定值時，閥門應(yīng)自動及時關(guān)閉，從而保護設(shè)備、容器或管路的安全運行。安全閥可以由閥門進口的系統(tǒng)壓力直接驅(qū)動，在這種情況下是由彈簧或重錘提供的機械載荷來克服作用在閥瓣下方的介質(zhì)壓力。它們還可以由個機構(gòu)來導(dǎo)驅(qū)動，該機構(gòu)通過釋放或施加個關(guān)閉力來使安全閥開啟或關(guān)閉。因此，按照上述驅(qū)動模式將安全閥分為直接作用式和導(dǎo)式。安全閥可以在整個開啟高度范圍或在相當(dāng)大的開啟高度范圍內(nèi)比例開啟，也可能僅在個微小的開啟高度范圍內(nèi)比例開啟，然后突然開啟到全開位置。
