The role of liquid sealing in chemical industry is expounded.
论述液封在化工生产中的作用。
Needle valve pressure better than other valves, sealing performance, it is generally used for small flow, high pressure gas or liquid sealing medium, also used in conjunction with the pressure gauge.
针型阀比其他阀门更能受压，密封性能好，所以一般用于较小流量，较高压力的气体或者液体介质的密封，还可与压力表配合使用。
During the pumping cycle the gas is in intimate contact with the sealing liquid and compression is nearly isothermal.
在抽运周期内，气体会与密封液和几乎等温的压缩气体紧密接触。
