湿式报警阀是一种只允许水单向流入喷水系统的报警单向阀。所以像这种报警阀，它要确保阀瓣前后的水压相等，这样才能够确保阀瓣前后的水压保持一个稳定平衡的状态。下面介绍一下，川消湿式报警阀的材质选择时候如何考虑耐腐蚀性能。

The wet alarm valve is an alarm one-way valve that only allows water to flow into the water spray system. Therefore, for such an alarm valve, it is necessary to ensure that the water pressure before and after the valve disc is equal, so that the water pressure before and after the valve disc can be kept in a stable and balanced state. The following focuses on how to consider the corrosion resistance when selecting the material of Chuanxiao wet alarm valve.

1、材料选择标准

1. Material selection criteria

为了确保它的耐腐蚀性能，所以在阀体以及阀盖的材质选择上面，一般考虑不得低于铸铁的材料制作。而在阀座的材质考虑上面要求采用，不低于青铜的材料去进行制作。

In order to ensure its corrosion resistance, the material selection of valve body and bonnet shall generally be no less than cast iron. As for the material of the valve seat, it is required to adopt a material no less than bronze.

2、零部件的材质选择

2. Material selection of components

为了确保它在转动以及滑动的过程当中零件能够发挥良好的作用，所以在选择的时候，一般考虑以青铜，黄铜或者奥氏体不锈钢这些耐腐蚀性能比较高的材料进行制作。如果换做其他的材质，那么它的耐腐蚀性的不可以低于上述这些材质的要求。

In order to ensure that the parts can play a good role in the process of rotation and sliding, it is generally considered to use bronze, brass or austenitic stainless steel with high corrosion resistance when selecting. If it is replaced with other materials, its corrosion resistance shall not be lower than the requirements of these materials.

3、过滤网材质

3. Filter material

在过滤网材质的选择上面，它的耐腐蚀性能要求也要较高。毕竟很多时候过滤网如果不能够发挥良好的作用，那么对于消防过程是有的阻碍的。所以对于延迟器设置的过滤网选择的材质，尤其要考虑它的耐腐蚀性能，一般以黄铜材质为主。

In the selection of filter material, its corrosion resistance is also required to be high. After all, many times, if the filter screen can not play a good role, it will hinder the fire fighting process. Therefore, as for the material selected for the filter screen set for the retarder, the corrosion resistance of the filter screen shall be particularly considered, and brass is generally the main material.

4、警铃喷嘴

4. Alarm nozzle

警铃喷嘴的材质选择也会考虑耐腐蚀，主要是因为要确保水力警铃喷嘴，在消防过程当中能够正常的发挥其功能和作用。如果条件允许的话，这一类的材质选择可能也会是以不低于黄铜的材料来进行制作。

The material selection of the alarm bell nozzle will also consider corrosion resistance, mainly because it is necessary to ensure that the hydraulic alarm bell nozzle can normally play its function and role in the fire process. If conditions permit, the material selection of this type may also be made of materials not lower than brass.

对于湿式报警阀而言，它的材质在选择上面，可能就是考虑如何起到耐腐蚀的作用。毕竟像这一类的报警阀，它是长期与水打交道的。的耐腐蚀性能要求，是必备的基本条件。您有什么疑问欢迎来我们网站http://www.cx-fire.com咨询了解！
