消防信號閘閥是消防設備中不可缺少的組成部分，如果消防信號閘閥出現外漏的情況，那么必定會影響消防的效果。所以一旦出現消防信號閘閥外漏必須要及時處理，下面這些方法是能夠外漏情況的，川消小編為您分析：
The fire signal gate valve is an indispensable component of fire equipment. If the fire signal gate valve leaks, it will inevitably affect the effectiveness of fire protection. So once there is an external leakage of the fire signal gate valve, it must be dealt with in a timely manner. The following methods can solve the leakage situation. Sichuan Xiaobian will analyze for you:
一、增加密封油脂
1、 Add sealing grease
對于還沒有使用密封油脂的閥體來說，增加密封油脂是能夠提高閥桿的密封性的，這樣可以降低閘閥出現泄漏的概率。平時在保養消防信號閘閥的時候也要注意定期增加密封油脂，這也是確保消防信號閘閥性能的有效方法。
For valve bodies that have not yet used sealing grease, adding sealing grease can improve the sealing performance of the valve stem, which can reduce the probability of gate valve leakage. When maintaining the fire signal gate valve, it is also important to regularly add sealing grease, which is an effective method to ensure the performance of the fire signal gate valve.
二、用透鏡墊密封
2、 Seal with lens pad
如果高溫高壓環境下，上下蓋的密封，閥座和上下閥體的密封如果是平面密封的話容易出現外泄情況，用電動調節閥透鏡墊來處理就能夠這個問題了。
If the seals of the upper and lower covers, valve seats, and upper and lower valve bodies are flat seals in high-temperature and high-pressure environments, it is easy to cause leakage. Using electric control valve lens pads can solve this problem.
三、添加填料
3、 Adding fillers
密封墊片的數量合理增加就能夠提高閥桿密封性。一般采取雙層或者多層混合填料的方式就能夠增加密封墊片數量，但是電動調節閥的防泄漏效果一般般。
A reasonable increase in the number of sealing gaskets can improve the sealing performance of the valve stem. Generally, double or multi-layer mixed packing can increase the number of sealing gaskets, but the anti leakage effect of electric control valves is generally average.
四、更換石墨填料
4、 Replace graphite packing
傳統填料對環境的適應能力比較差，如果工作溫度低于20攝氏度或者高于200攝氏度的話，它的老化速度加快，壽命縮短。但是使用石墨填料能夠克服這些困難，不但有較長使用壽命，而且還大大的提升了密封性。但是石墨填料也存在缺陷，突出的就是它的回差比較大，有時候會出現爬行現象。為了這個問題，可以在設計安裝電動調節閥時候做出相應的調整。
Traditional fillers have poor adaptability to the environment. If the working temperature is lower than 20 degrees Celsius or higher than 200 degrees Celsius, their aging rate will accelerate and their lifespan will be shortened. However, using graphite fillers can overcome these difficulties, not only has a longer service life, but also greatly improves sealing performance. However, graphite fillers also have defects, particularly in their large backlash and sometimes crawling. To solve this problem, corresponding adjustments can be made when designing and installing electric control valves.
In short, the leakage of the fire signal gate valve can have adverse effects, and if problems occur, timely resolution can reduce the losses caused by the leakage. You can take the above methods to improve it. If you don't know how to handle it, find a professional Chuanxiao http://m.xintli.net The company went to help handle it.
