What issues should be noted when installing hydraulic extraction check valves?
When installing a hydraulic extraction check valve, the following issues should be noted:
Matching pipeline specifications: Before installation, it is necessary to confirm that the selected check valve matches the pipeline specifications to ensure that the size is in line and avoid problems caused by size mismatch.
Cleaning the pipeline: Before installation, it is necessary to clean the debris and impurities inside the pipeline to ensure that it is clean and unobstructed, in order to avoid malfunctions caused by impurities during installation or use.
Flow direction: The installation position and direction of the check valve must ensure that the direction of medium flow is consistent with the direction indicated by the arrow on the valve body. The arrow of a check valve is usually used to indicate the normal flow direction of the pipeline. If the installation direction is opposite to the arrow direction, the valve will not function properly.
Tightening and fixing: Use appropriate tools and methods to fasten and fix the check valve to the pipeline, and ensure that the fasteners are firm and reliable. Either too loose or too tight can cause the valve to malfunction or be damaged.
Appearance and performance inspection: Before installation, conduct an appearance inspection of the check valve to ensure the integrity of the nameplate and compliance with current national standards. At the same time, conduct strength and tightness performance tests to ensure that the performance of the check valve meets the design requirements.
Installation position: The installation position, height, and inlet/outlet direction of the check valve must meet the design requirements. Especially for check valves where the valve disc slides along the vertical centerline of the valve body (such as lift check valves), they can only be installed in specific pipeline positions and directions.
Noise, leakage, and blockage issues: After installation, attention should be paid to the operation of the check valve. If there are problems such as loud noise, leakage, or blockage, they need to be dealt with and adjusted in a timely manner.
The above are the main issues to pay attention to when installing hydraulic extraction check valves. Following these steps and precautions can ensure the correct installation and normal operation of the check valve.
