Threaded Ball Check Valve Installation and Maintenance
Threaded ball check valve is a valve that prevents water or other fluids from flowing backward. It uses a rubber sheathed ball as the valve disc, which has the advantages of good sealing performance, good noise reduction effect, and no water hammer. So, how to install and maintain threaded ball check valve? This article will introduce you to the installation and maintenance methods of threaded ball check valves, and I hope it will be helpful to you.
Installation method of threaded ball check valve
- Choose a suitable installation location: the threaded ball check valve should be installed at the outlet of the water pump to prevent the water pump from reversing. At the same time, the check valve should be protected from shock or vibration, so as not to affect its service life.
- Pay attention to the flow direction of the medium: the flow direction of the medium of the threaded ball check valve should be consistent with the direction of the arrow marked on the valve body, otherwise it will affect the normal operation of the valve. If the flow direction of the medium is not clear, you can open the valve to observe the movement of the rolling ball to determine the correct flow direction.
- Threaded connection method: threaded ball check valve adopts threaded connection method. During installation, attention should be paid to the connection with the pipeline to prevent water leakage or loosening. If the thread specifications of the pipe and the valve are inconsistent, an adapter or a flange can be used for connection. Sealant or sealing tape should be used to enhance the sealing performance during installation.
- Guarantee the free rolling of the rolling ball: the threaded ball check valve can be installed horizontally or vertically, but it must be ensured that the rolling ball can roll up and down freely to realize the opening and closing of the valve. If the balls become seized or seized, the valve will fail or be damaged.
Maintenance method of threaded ball check valve
- Regular inspection and cleaning: The threaded ball check valve should be regularly inspected to remove the sundries in the valve body to keep the passage unblocked. If sediment or dirt is found, it can be cleaned with a soft cloth or soft brush, and avoid scratching the ball or valve seat with hard objects.
- Check and replace the seals: Check the sealing performance of the ball and seat for threaded ball check valves, and replace them in time if they are worn or damaged. If water leakage is found, the threaded connection can be tightened, or the sealant or tape can be replaced.
- Prevent frost cracking and corrosion: threaded ball check valves should choose appropriate materials and coatings according to the use environment and medium characteristics to enhance their performance such as frost resistance, corrosion resistance, and wear resistance. When using in a low temperature environment, attention should be paid to emptying the water in the pipe to avoid freezing and cracking. When used in a high temperature environment, care should be taken to avoid thermal expansion and contraction caused by overheating or overcooling.
The above is the introduction of the installation and maintenance methods of the threaded ball check valve. I hope you can use and maintain the threaded ball check valve correctly to prolong its service life and ensure the safe operation of the pipeline system.
