進口消聲止回閥安裝與維護：

1,本閥門通路兩端須堵塞，存在干燥通風的室內。如長期存放，應經常檢查防銹蝕。

2,安裝前應將閥門清洗干凈，并消除在運輸過程中造成的缺陷。

3,安裝時必須仔細核對閥門上的標志和銘牌是否符合使用要求。

4,升降式垂直瓣止回閥應安裝在垂直管道上。

5,升降式水平瓣止回閥應安裝在水平管道上。

6,在管線中不要使止回閥承受重量，大型的止回閥應獨立支撐，使之不受管系產生的壓力的影響。

7,安裝止回閥時，應特別注意介質流動方向，應使介質正常流動方向與閥體上指示的箭頭方向相一致，否則就會截斷介質的正常流動。底閥應安裝在水泵吸水管路的底端。

8,通式升降式止回閥應安裝于水平管路上,立式升降式止回閥和底閥一般安裝在垂直管路上,并且介質自下而*動。

9,止回閥關閉時，會在管路中產生水錘壓力，嚴重時會導致閥門、管路或設備的損壞，尤其對于大口管路或高壓管路，故應引起止回閥選用者的高度注意。

Installation and maintenance of inlet silencing check valve:
1. Both ends of the valve passage must be blocked, and there is a dry and ventilated room. If it is stored for a long time, it should be checked frequently for anti-corrosion.
2. Clean the valve before installation and eliminate the defects during transportation.
3. During installation, it is necessary to carefully check whether the marks and nameplates on the valve meet the use requirements.
4. The lift type vertical disc check valve shall be installed on the vertical pipeline.
5. Lift type horizontal disc check valve shall be installed on horizontal pipeline.
6. Don't make the check valve bear weight in the pipeline. Large check valves should be supported independently, so that they are not affected by the pressure generated by the piping system.
7. When installing the check valve, special attention should be paid to the flow direction of the medium, so that the normal flow direction of the medium is consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be cut off. The bottom valve shall be installed at the bottom of the water pump suction pipe.
8. The general lift check valve should be installed on the horizontal pipeline, while the vertical lift check valve and bottom valve are generally installed on the vertical pipeline, and the medium flows from bottom to top.
9. When the check valve is closed, it will produce water hammer pressure in the pipeline, and in serious cases, it will cause damage to the valve, pipeline or equipment, especially for the large mouth pipeline or high-pressure pipeline, so the check valve selector should pay close attention to it.
