氣液增壓泵閥門(mén)在運用過(guò)程中常常會(huì )呈現一些讓人攪擾的問(wèn)題，比方說(shuō)閥門(mén)關(guān)不嚴、關(guān)不緊，那該怎樣辦呢？下面小編為您解答。
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.
普通狀況下，假如是關(guān)不嚴的話(huà)，先確認一下看看閥門(mén)能否有關(guān)閉到位，假如曾經(jīng)關(guān)閉到位后，還是存在走漏不能密封，那就在檢查密封面的狀況，有些閥門(mén)的密封副是可拆卸的。那就拿出來(lái)停止研磨，再次實(shí)驗，當然假如還是關(guān)不嚴的話(huà)，那就必需返廠(chǎng)檢修或者改換閥門(mén)，以免影響閥門(mén)正常運用及呈現工況事故等問(wèn)題。
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.
假如氣液增壓泵閥門(mén)呈現關(guān)不嚴的狀況，應該先找出問(wèn)題呈現在哪里，然后依據相應的辦法去處理處置，普通閥門(mén)關(guān)不嚴的緣由有以下幾種：
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）有雜質(zhì)卡在密封面，雜物堆積在閥門(mén)底處或墊在閥瓣與閥座之間；
(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）閥桿螺紋生銹，閥門(mén)無(wú)法轉動(dòng)；
(2) The valve rod thread is rusted and the valve cannot rotate;
（3）閥門(mén)密封面被毀壞，招致介質(zhì)呈現走漏；
(3) The sealing surface of the valve is damaged, causing medium leakage;
（4）閥桿與閥瓣銜接不好，使閥瓣與閥座偏斜不能緊密接觸；
(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;
應對辦法：
Countermeasures:
一、有雜質(zhì)卡住閥門(mén)密封面
1、 The valve sealing surface is stuck by impurities
1.閥門(mén)有時(shí)忽然關(guān)不嚴，可能是閥門(mén)密封面間有雜質(zhì)卡住，此時(shí)不應用力強行關(guān)閉，應把閥門(mén)稍開(kāi)大一些，然后在試圖關(guān)閉，重復試試，普通即可掃除，否則應停止檢查，應堅持介質(zhì)的質(zhì)量干凈。
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、閥桿螺紋生銹
2、 Rust on valve rod thread
關(guān)于通常在開(kāi)啟狀態(tài)的閥門(mén)，偶爾關(guān)閉時(shí)，由于閥桿螺紋曾經(jīng)生銹，也會(huì )發(fā)作關(guān)不嚴的狀況。關(guān)于這種狀況，可重復開(kāi)關(guān)幾次閥門(mén)。同時(shí)用小錘敲擊閥體底部，即能將閥門(mén)冠巖，無(wú)需對閥門(mén)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、閥門(mén)密封面被毀壞
3、 The valve sealing surface is damaged
關(guān)于試著(zhù)屢次開(kāi)關(guān)依然關(guān)不緊的狀況，那就是密封面已損壞了，應報修，又或者腐蝕、介質(zhì)中的顆粒劃傷等毀壞了密封面，也應報修。
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、閥桿與閥瓣銜接不好
4、 Poor connection between valve rod and disc
經(jīng)常給閥桿和閥桿螺母加光滑油，以保證閥門(mén)的開(kāi)關(guān)靈敏，要有一套正軌的維護計劃。
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.
