There will be safety valve in electric heating furnace, how to avoid failure when using it? Let's give you a detailed introduction.

在冬季的取暖工作中，安全是一个非常重要的问题，所以现在采暖炉在生产时都会安装一个安全阀，但是安全阀也难免会出现故障，下面我们来看看采暖炉安全阀发生故障的原因。

In the winter heating work, safety is a very important problem, so now the heating furnace in production will install a safety valve, but the safety valve will inevitably fail, let's see the cause of the failure of the safety valve of the heating furnace.

1、安装、检修工艺不良，校验不准确。

1. The installation and maintenance process is poor and the calibration is not accurate.

2、运行中安全门零件部件变形卡涩，弹簧失效等使启闭受阻，动作不灵活。

2. During the operation, the safety door parts are deformed and jammed, and the spring fails, which makes the opening and closing blocked and the action is inflexible.

3、长期关闭，阀芯与阀座互相粘住或其他部件锈死。

3. Long term closure, valve core and valve seat adhere to each other or other parts rust.

4、频繁启闭使密封面被冲刷损坏。

4. Frequent opening and closing causes the sealing surface to be scoured and damaged.

5、阀芯与阀座间有杂物，结合不严密。

5. There are impurities between valve core and valve seat, and the connection is not tight.

以上就是电采暖炉安全阀发生故障的原因，希望能够对大家有所帮助。

The above is the reason for the failure of the safety valve of the heating furnace, hoping to help everyone.
