burkert3234型手動(dòng)零死區(qū)T形膜片閥,德國burkert手動(dòng)閥,寶德氣動(dòng)膜片閥
burkert3234型手動(dòng)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(hù)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(shí)，閥門自動(dòng)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(shí)，閥門應(yīng)自動(dòng)及時(shí)關(guān)閉，從而保護(hù)設(shè)備、容器或管路的安全運(yùn)行。安全閥可以由閥門進(jìn)口的系統(tǒng)壓力直接驅(qū)動(dòng)，在這種情況下是由彈簧或重錘提供的機(jī)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(gè)機(jī)構(gòu)來導(dǎo)驅(qū)動(dòng)，該機(jī)構(gòu)通過釋放或施加個(gè)關(guān)閉力來使安全閥開啟或關(guān)閉。因此，按照上述驅(qū)動(dòng)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(gè)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(gè)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。
