消防信号闸阀是消防设备中不可缺少的组成部分，如果消防信号闸阀出现外漏的情况，那么必定会影响消防的效果。所以一旦出现消防信号闸阀外漏必须要及时处理，下面这些方法是能够外漏情况的，川消小编为您分析：

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

对于还没有使用密封油脂的阀体来说，增加密封油脂是能够提高阀杆的密封性的，这样可以降低闸阀出现泄漏的概率。平时在保养消防信号闸阀的时候也要注意定期增加密封油脂，这也是确保消防信号闸阀性能的有效方法。

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、用透镜垫密封

2、 Seal with lens pad

如果高温高压环境下，上下盖的密封，阀座和上下阀体的密封如果是平面密封的话容易出现外泄情况，用电动调节阀透镜垫来处理就能够这个问题了。

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

密封垫片的数量合理增加就能够提高阀杆密封性。一般采取双层或者多层混合填料的方式就能够增加密封垫片数量，但是电动调节阀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、更换石墨填料

4、 Replace graphite packing

传统填料对环境的适应能力比较差，如果工作温度低于20摄氏度或者高于200摄氏度的话，它的老化速度加快，寿命缩短。但是使用石墨填料能够克服这些困难，不但有较长使用寿命，而且还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较大，有时候会出现爬行现象。为了这个问题，可以在设计安装电动调节阀时候做出相应的调整。

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.

总之，消防信号闸阀的泄漏会带来不良影响，出现问题只要及时那么就能够降低因泄漏导致的损失。可以采取以上这几点方法去改善一下，如果不知道怎么处理的话，找的川消http://www.cx-fire.com公司去帮忙处理。
