The service life of valves has always been a problem that users are very concerned about. The service life of products such as check valves mainly comes from the manufacturing process and raw materials, and partly from the use environment and maintenance.
In the design and manufacturing stage of the check valve, the manufacturer will check the performance of the product and the quality of its own brand as strictly as possible, so as to achieve good results in the design and manufacture of the check valve. Therefore, most of the check valves that can pass the factory qualification inspection stage are guaranteed to reach the normal service life. After the user purchases, the service life will be affected from the time of transportation. During transportation, if the check valve is improperly placed and damaged to a certain extent, the service life will naturally be shortened. Secondly, for the use environment of the check valve, if the use environment is poor and the maintenance is improper, the service life of the check valve will be shortened accordingly.
The valve body of the check valve is also inevitably contaminated and corroded due to prolonged exposure. For the cleaning of its surface, like other valves, it can be cleaned with the appropriate medium, and after the cleaning is completed, a certain anti-rust oil or anti-fouling coating is applied to it.
