按照标准要求，消防信号蝶阀的额定工作压力应不低于1.2MPa，并应能承受2倍额定工作压力的静水压，保持5min，试验中蝶阀密封处应无渗漏。下面来讲讲川消消防信号蝶阀阀门漏水或阀门壳体破裂问题。

According to the standard requirements, the rated working pressure of the fire signal butterfly valve shall not be less than 1.2MPa, and it shall be able to withstand the hydrostatic pressure twice the rated working pressure for 5min. There shall be no leakage at the sealing part of the butterfly valve during the test. Next, we will talk about the leakage of the valve of Chuanxiao fire signal butterfly valve or the rupture of the valve shell.

工程中偶而有用户反应阀门关不死

Occasionally in the project, the user responded that the valve could not be closed

a、如果水质不符合要求，内有杂质或施工残余杂质在阀门上，造成阀门关闭不到位，那就一定会出现渗漏问题，可试用冲洗的方法来。

a. If the water quality does not meet the requirements, and there are impurities or construction residual impurities left on the valve, resulting in the valve not being closed properly, the leakage problem will certainly occur, and the flushing method can be used to solve it.

b、倘若施工不注意，蝶阀两端的连接管道同心度有偏差，也会造成蝶阀关闭不到位，造成渗漏，施工人员可重新调整管道的同心度后进行管道安装。

b. If the concentricity of the connecting pipes at both ends of the butterfly valve is deviated due to carelessness in construction, the butterfly valve may not be closed in place, resulting in leakage. The construction personnel can re adjust the concentricity of the pipes before installing the pipes.

阀门壳体破裂

Valve shell rupture

工程中，偶尔也有用户反映消防信号蝶阀壳体破裂，出现不能升压或外部渗漏，该情况发生不多。毫无疑问，像这种情况只能判断为可能在运输途中，或是搬运、储存、施工、安装等环节中造成的。

In the project, some users occasionally report that the shell of the fire signal butterfly valve is broken, and there is no pressure rise or external leakage, which is rare. There is no doubt that such a situation can only be judged as possibly caused during transportation, or during transportation, storage, construction, installation and other links.

因为消防蝶阀一般安装在离地面较高的建筑平顶下方，施工人员如果不慎跌落或出现野蛮搬运，定可造成信号蝶阀壳体破裂，毕竟普通信号蝶阀阀体是一般性的HT200铸铁，材料的材质比较脆，容易断裂，所以必须小心搬运，小心轻放。

Because the fire butterfly valve is generally installed under the flat roof of the building which is higher from the ground, if the construction personnel fall down carelessly or carry it savagely, the shell of the signal butterfly valve will be broken. After all, the valve body of the ordinary signal butterfly valve is a general HT200 cast iron, and the material is relatively brittle and can be easily broken. Therefore, it must be handled with care.

当阀体确认破裂后，该阀门就报废了，只能进行调换处理，当然责任方应当承担相应的费用。您对此有什么疑问可以来我们网站http://www.cx-fire.com进行咨询！

When the valve body is confirmed to be broken, the valve is scrapped and can only be replaced. Of course, the responsible party shall bear the corresponding costs. If you have any questions about this, you can come to our website http://www.cx-fire.com Consult!
