1、在管线中不要使止回阀承受重量,大型的止回阀应*支撑,使之不受管系产生的压力的影响。

2、安装时注意介质流动的方向应与阀体所票箭头方向一致。

3、升降式垂直瓣止回阀应安装在垂直管道上。

4、升降式水平瓣止回阀应安装在水平管道上。

升降式止回阀的性能及其安装注意事项:

1、在管线中不要使止回阀承受重量,大型的止回阀应*支撑,使之不受管系产生的压力的影响。

2、安装时注意介质流动的方向应与阀体所票箭头方向一致。

3、升降式垂直瓣止回阀应安装在垂直管道上。

4、升降式水平瓣止回阀应安装在水平管道上。

办消防手续是一个很复杂的事情，要想通关消防检查，其中止回阀就需要安装到位，那么我们在安装时需要注意哪些问题呢?

1、升降式水平瓣止回阀应安装在水平管道上。

2、升降式垂直瓣止回阀应安装在垂直管道上。

3、安装止回阀时，应特别注意介质流动方向，应使介质正常流动方向与阀体上指示的箭头方向相一致，否则就会截断介质的正常流动。底阀应安装在水泵吸水管路的底端。

4、旋启式止回阀安装位置不妥限制，通常安装于水平管路，但也可以安装于垂直管路或倾料管路上。

5、通式升降式止回阀应安装于水平管路上,立式升降式止回阀和底阀一般安装在垂直管路上,并且介质自下而上流动。

6、在管线中不要使止回阀承受重量，大型的止回阀应*支撑，使之不受管系产生的压力的影响。

7、双瓣旋启式止回阀适用于大中口径管路。对夹双瓣旋启式止回阀结构小、重量轻，是一种发展较快的止回阀;多瓣旋启式止回阀适用于大口径管路。

8、单瓣旋启式止回阀一般适用于中等口径的场合。大口径管路选用单瓣旋启式止回阀时，为减少水锤压力，最好采用能减小水锤压力的缓闭止回阀。
