The use of check valves is very important and can meet the needs of daily life, but you must know the types you need to use at home. Below, the China hydraulic ball valve factory introduces the installation precautions of check valves:
1. In the process of installing the check valve, it is necessary to consider where the medium flows in the pipeline. The arrow on the surface of the check valve must point in the same direction as the medium, so as to ensure the normal operation in the later stage. use.
2. The installation of the check valve must be in a vertical pipeline to ensure its normal use. That is to say, if the pipeline is placed horizontally and the wafer check valve is installed, the check valve must be installed vertically.
3. If two check valves of wafer type and disc type are installed, then attention should be paid to the connection between the check valves. It is necessary to connect a telescopic tube between them to ensure normal operation. Never connect a clip-on check valve directly to another check valve.
4. When operating the valve plate, it is necessary to try not to add joints or blockages within the scope of its operation. In addition, reducing pipes cannot be installed on both sides of the wafer check valve.
5. If you plan to install a check valve around the elbow of the pipeline, make sure to reserve enough space. Moreover, at the outlet of the water pump, it is necessary to let it flow out about six times the size of the valve, so as to ensure that the disc can be affected by the fluid.
