放气阀

On the base of wellbore fluid analysis, the math model, which decided the annular air bleeder's reasonable operation rules, has been established, which can guide the oil well production.

并在井筒流体分析的基础上，建立了确定环空放气阀合理工作制度的数学模型，用于指导油井的生产。

When using a vacuum desiccator, turning on a desiccator's air escape valve directly before shutting

使用真空干燥器时，未关闭真空泵就直接开干燥器的放气阀，结果使泵内的机油

Check up double-stop valve and examine whether the switch of pressure meter opens or not, vent valve close or not.

1.2 检查双联截止阀及压力表开关是否已打开，放气阀是否已关闭。

Using this feature with the Purge Valve closed can result in over pressurizing the system or exceeding the Pressure Safety Relief Valve setting.

在放气阀关闭时使用这个功能，可能会导致系统压力过大或超过压力安全阀的设置压力。

The tank is equipped multiplex safety devices and instruments: Imported combination of pressure gauge and liquid level meter, interlayer equipped with outer cylinder explosion-proof device, the inner barrel equipped with combined safety system (combination system of double safety valve bursting diaphragm), discharge outlet of the safety valve and air valve adopting centralized collecting piping and discharging through the fire barrier

罐体设置有多重安全装置和仪表：配置进口压力表液位计组合，夹层设有外筒防爆装置，内筒设有组合安全系统（双安全阀爆破膜组合系统），安全阀和放气阀的排放口采用集中回收管道通过阻火器进行排放

In the light of low pump efficiency resulted in the effect of gas in the middle and later period of the development ofoil fields in China, a casing pressure lelif valve is ricveloped.

针对我国油田开发中后期抽油泵采油中由于气体影响使泵效降低的问题，研制出一种套管定压放气阀。

Applied to adjust the casing pressure for ESP wells, it automatically discharges through the bleeding valve, the casing gas into oil/gas manifold, for the purpose of controlling the reasonable submergence depth of ESP intake, and preventing the shut-down of ESP due to gas lock or under-load. This not only ensures the normal pump operation but also enhances the pump efficiency and production rate.

常用于电潜泵套管压力调节，套管气通过放气阀排入输油管汇，以控制合理的电泵吸入口沉没度，防止潜油电泵发生因气锁现象的发生导致的欠载停泵，保证电泵的正常运行，提高泵效及产量。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
