气液增压泵阀门在运用过程中常常会呈现一些让人搅扰的问题，比方说阀门关不严、关不紧，那该怎样办呢？下面小编为您解答。
The valve of gas-liquid booster pump often presents some disturbing problems in the process of application, for example, if the valve is not tightly closed, what should be done? The following section will answer your question.
普通状况下，假如是关不严的话，先确认一下看看阀门能否有关闭到位，假如曾经关闭到位后，还是存在走漏不能密封，那就在检查密封面的状况，有些阀门的密封副是可拆卸的。那就拿出来停止研磨，再次实验，当然假如还是关不严的话，那就必需返厂检修或者改换阀门，以免影响阀门正常运用及呈现工况事故等问题。
Under normal circumstances, if it is not closed tightly, first confirm whether the valve can be closed in place. If there is leakage and no sealing after it has been closed in place, then check the condition of the sealing surface. Some valve sealing pairs are removable. Then take it out to stop grinding and experiment again. Of course, if it is still not closed tightly, it is necessary to return to the factory for maintenance or change the valve to avoid affecting the normal operation of the valve and presenting problems such as working conditions and accidents.
假如气液增压泵阀门呈现关不严的状况，应该先找出问题呈现在哪里，然后依据相应的办法去处理处置，普通阀门关不严的缘由有以下几种：
If the valve of the gas-liquid booster pump is not tightly closed, first find out where the problem is, and then deal with it according to the corresponding methods. Common reasons for the valve not being tightly closed are as follows:
（1）有杂质卡在密封面，杂物堆积在阀门底处或垫在阀瓣与阀座之间；
(1) Impurities are stuck on the sealing surface, and sundries are piled up at the bottom of the valve or placed between the valve clack and the valve seat;
（2）阀杆螺纹生锈，阀门无法转动；
(2) The valve rod thread is rusted and the valve cannot rotate;
（3）阀门密封面被毁坏，招致介质呈现走漏；
(3) The sealing surface of the valve is damaged, causing medium leakage;
（4）阀杆与阀瓣衔接不好，使阀瓣与阀座偏斜不能紧密接触；
(4) The connection between the valve rod and the valve disc is not good, so that the valve disc and the valve seat can not be closely contacted due to deflection;
应对办法：
Countermeasures:
一、有杂质卡住阀门密封面
1、 The valve sealing surface is stuck by impurities
1.阀门有时忽然关不严，可能是阀门密封面间有杂质卡住，此时不应用力强行关闭，应把阀门稍开大一些，然后在试图关闭，重复试试，普通即可扫除，否则应停止检查，应坚持介质的质量干净。
1. Sometimes the valve cannot be closed tightly, which may be caused by impurities stuck between the sealing surfaces of the valve. At this time, the valve should be opened a little wider without force, and then tried to close again. If it is normal, it can be cleaned, otherwise the inspection should be stopped, and the quality of the medium should be clean.
二、阀杆螺纹生锈
2、 Rust on valve rod thread
关于通常在开启状态的阀门，偶尔关闭时，由于阀杆螺纹曾经生锈，也会发作关不严的状况。关于这种状况，可重复开关几次阀门。同时用小锤敲击阀体底部，即能将阀门冠岩，无需对阀门停止研磨修理。
As for the valve normally in the open state, sometimes when it is closed, the valve rod thread has rusted, and the valve can also be loosely closed. In this case, the valve can be opened and closed several times. At the same time, knock the bottom of the valve body with a small hammer to crown the valve without grinding and repairing the valve.
三、阀门密封面被毁坏
3、 The valve sealing surface is damaged
关于试着屡次开关依然关不紧的状况，那就是密封面已损坏了，应报修，又或者腐蚀、介质中的颗粒划伤等毁坏了密封面，也应报修。
As for the condition that the switch cannot be closed tightly after repeated attempts, the sealing surface has been damaged and should be reported for repair, or the sealing surface has been damaged by corrosion or particles in the medium.
四、阀杆与阀瓣衔接不好
4、 Poor connection between valve rod and disc
经常给阀杆和阀杆螺母加光滑油，以保证阀门的开关灵敏，要有一套正轨的维护计划。
Add lubricating oil to the valve rod and valve rod nut frequently to ensure the sensitivity of valve opening and closing. A set of normal maintenance plan is required.
