Sanitary Check Valve The methods to avoid excessive opening and closing mainly include correct installation, regular inspection and maintenance, and reasonable use.

Correct installation
Choose the appropriate model and specification: According to the actual needs of the pipeline system, select the appropriate sanitary check valve model and specification to ensure that it can withstand the working pressure and temperature of the system, and avoid excessive opening or closing problems caused by improper selection.
Follow the installation specifications: During the installation process, the manufacturer's installation guide should be strictly followed to ensure that the installation position, direction and connection method of the valve are correct to avoid improper installation affecting the normal opening and closing of the valve.
Regular inspection and maintenance
Appearance inspection: Regularly check whether there are cracks, rust or other damage on the outer surface of the valve. If there are any problems, they should be handled in time to prevent valve failure caused by appearance damage.
Sealing performance inspection: Ensure that the valve is well sealed and there is no leakage. You can observe whether there are signs of leakage around the valve or use professional tools for detection. Once a leak is found, it should be repaired or replaced immediately.
Cleaning and lubrication: Regularly remove dust and dirt from the valve surface, and apply an appropriate amount of lubricant to the parts that need lubrication to reduce friction and wear and maintain the flexibility and sealing performance of the valve.
Reasonable use
Avoid frequent operation: During normal use, frequent opening and closing operations of sanitary check valves should be avoided to reduce valve wear and failure rate.
Pay attention to medium characteristics: According to the characteristics of the medium in the pipeline, select appropriate valve materials and sealing materials to avoid valve damage or excessive opening and closing due to medium corrosion or high temperature.
Establish maintenance files: Establish maintenance files for check valves, record the time, content, replaced parts and other information of each maintenance, so as to track the maintenance history of the valve and predict future maintenance needs to ensure the long-term stable operation of the valve.

Through the above methods, the problem of excessive opening and closing of sanitary check valves can be effectively avoided, its service life can be extended, and the normal operation of the pipeline system and product quality can be ensured.
