vt.降低壓力；減壓

And the higher the depressurizing rate is,the higher the gas production rate i... 降壓速度越慢,當(dāng)壓力降到相同水平時(shí)累積產(chǎn)氣量百分比越大,特別在降壓初期這一現(xiàn)象更明顯。

All pressure instruments shall have a vent valve to provide the capability of depressurizing the sensing line after the block valve is closed. 所有壓力儀表應(yīng)配備一個(gè)排氣閥，以便在截止閥關(guān)閉后能夠使導(dǎo)壓管泄壓。

The former scheme controls the corresponding valve by fixed pressurizing and depressurizing time and the latter by settled flux cumulation volume. 前者通過設(shè)定合理的增壓及泄壓時(shí)間來控制相應(yīng)電磁閥開閉,后者通過儀表設(shè)定合理的流量累積體積來控制相應(yīng)電磁閥開閉。

The former afterheat utilizing system generates electricity by burning oil to super-heat saturated steam and drive the steam turbine or depressurizing throu gh a decompressor. 金隆銅業(yè)有限公司原余熱利用系統(tǒng)采用燃油在過熱爐中將飽和蒸汽過熱后,再由多級(jí)汽輪機(jī)發(fā)電,或者采用減壓閥減壓。
