气液增压泵阀门关不严的缘由及处置办法

  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?
  The valve of gas-liquid booster pump often presents some disturbing problems in the operation process, such as the valve is not closed tightly, how to do?
  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 conditions, if it is not strictly closed, first confirm to see if the valve can be closed in place, if once closed in place, there is still leakage can not be sealed, 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 strictly closed, it is necessary to go back to the factory to repair or replace the valve, so as to avoid affecting the normal operation of the valve and the occurrence of working conditions accidents.
  假如气液增压泵阀门呈现关不严的状况,首先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 of all, we should find out where the problem appears, and then deal with it according to the corresponding methods. The reasons for the tightness of the ordinary valve 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;(2)阀杆螺纹生锈,阀门无法转动;(3)阀门密封面被毁坏,招致介质呈现走漏;(4)阀杆与阀瓣衔接不好,使阀瓣与阀座偏斜不能紧密接触;阀门关不严的处置办法:

  (1) There are impurities stuck on the sealing surface, which accumulate at the bottom of the valve or between the disc and the seat; (2) the threads of the valve stem are rusty and the valve cannot turn; (3) the sealing surface of the valve is destroyed, causing leakage of the medium; (4) the connection between the stem and the disc is not good, so that the disc and the seat can not be tightly contacted; and the disposal method of improper closure of the valve is as follows:
  一、有杂质卡住阀门密封面
  1. Impurity stuck on valve sealing surface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。
  Sometimes the valve suddenly closed lax, may be the impurity between the sealing surface of the valve jammed, at this time should not be forced to close, the valve should be slightly larger, and then try again, ordinary can be swept away, or should stop checking, should adhere to the quality of the media clean.
  二、阀杆螺纹生锈
  2. Rust on valve stem threads
  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 valves normally in open state, occasionally when they are closed, improper closure will occur due to rusting of stem threads. In this case, the valve can be repeatedly switched on and off several times. At the same time, tapping the bottom of the valve body with a small hammer can make the valve crown rock, without the need to stop grinding and repairing the valve.
  三、阀门密封面被毁坏
  3. Valve sealing surface destroyed
  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 situation that the switch is still not tightly closed after repeated attempts, that is, the sealing surface has been damaged and should be repaired, or the sealing surface has been damaged by corrosion, particle scratches in the medium, etc., should also be repaired.
  四、阀杆与阀瓣衔接不好
  4. Poor connection between stem 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。
  Smooth oil is often added to the stem and stem nut to ensure that the valve is switched on and off sensitively, and a maintenance plan for the right track is required.
