When purchasing swing check valves, we all hope to ensure their quality, even if the price is slightly higher. We definitely hope to purchase valves from large brands, and ensuring quality is the most crucial thing. But in reality, only by using the valve correctly and doing a good job in installation and maintenance can its service life be truly extended. Here are some methods to extend its service life.
Pre installation work
Before installation, we need to remove the covers and foam plates on both sides of the swing check valve, and clean the valve body as a whole. The inner cavity is free of any oil stain. And the oil paper on the surface of the valve disc should also be removed, and basic cleaning work should be done well. Valves are all marked with flow direction, and the positive and negative directions should be determined, and incorrect installation is not allowed. Moreover, the medium inside the pipeline should not have any hard particles to avoid affecting its cover. To install the check valve, it is necessary to ensure that it is not damaged and meets our actual needs and specifications.
Key points of installation
In order to ensure the correct application of swing check valves, the installation position in the pipeline should not allow the check valve to bear weight, and special attention should be paid to avoid the impact of pipeline pressure on it. There will be marked arrows on the valves, and the direction of medium flow must be consistent with it to ensure compliance with subsequent use without being affected. Because once the installation is reversed, it may lead to accidents, so it is also necessary to conduct a thorough inspection after the installation is completed.
Daily maintenance work
Before using a swing check valve, its storage location needs to be ventilated, dry, and cannot be directly placed in the open air. Before use, it is also necessary to do a good job of cleaning, and damaged check valves cannot be installed and used. At the same time, we should pay special attention to the maintenance work after installation and use. If there are certain problems, they should also be dealt with in a timely manner. At each stage, it is necessary to inspect its sealing and connection position to determine whether the valve body needs to be replaced.
