Wafer check valve is a kind of check valve, which belongs to automatic valve, and is often used in the water supply and drainage pipeline system. This wafer check valve can open and close the valve door correspondingly according to the changes of the fluid medium in the pipeline system, so as to avoid the phenomenon of reverse flow in the pipeline.
how to store the wafer type check valve?
- The wafer type check valve should be placed in a dry and ventilated room, and its both ends of passage should be blocked;
- For a long time storage, the wafer check valve should be checked regularly to remove the dirt, special attention should be paid to the cleaning of the sealing surface to prevent damage to the sealing surface.
How to install a wafer type check valve:
- Before the wafer check valve is installed, the wafer check valve should be carefully checked whether the valve mark conforms to the use requirements.
- Before the installation of wafer type check valve, check the inner cavity and sealing surface of the check valve, if there is any dirt, it should be wiped with a cleaning cloth in time.
- Before the installation of the wafer type check valve, it should be noted that the flow direction arrow mark on the valve body should be consistent with the flow direction of the medium.
- According to the requirements of the pipelines, the wafer butterfly type check valve can be installed horizontally or vertically.
- During the use of the wafer type check valve, attention should be paid to check whether the wafer check valve is creating abnormal sound and vibration. In order to prevent the water hammer effect in the pipeline, attention should be paid to the fluctuation of medium pressure in the pipelines.
