The installation of the directional valve is a very important step, only the correct installation can ensure the safe use of the reversing valve, the following is the detailed installation steps of the reversing valve, must be carefully read before formal use to ensure that the reversing valve can operate normally.
1. Installation
(1) Confirm the installation environment
Before installing the directional valve, it must be ensured that the installation environment is dry, dust-free, free of strong vibration and free of corrosive media. At the same time, the installation position of the valve should be convenient for operation and maintenance.
(2) Clean up the pipeline
During the installation process, it is important to ensure that the valve inlet and outlet pipes are clean to prevent impurities from entering the valve and affecting the valve performance.
(3) Connection method
The connection methods of the directional valve mainly include flange connection, threaded connection and welding, etc., which connection method to choose needs to be decided according to the actual working conditions, and ensure that the connection is firm and reliable.
(4) Installation direction
When installing the directional valve, the direction of the valve stem should be determined according to the requirements of the manufacturer's manual. In general, the valve stem direction should be consistent with the pipe direction, which can facilitate operation and maintenance.
(5) Installation method
First, plug each hose into the corresponding position of the directional valve in turn, taking care not to insert the hose in the wrong position. After installing the reversing valve, use a Phillips screwdriver to lock the fixing screw back, and finally arrange the wires, and arrange the wire terminals according to the principle of color to color, number of holes to number of holes and number of holes into the cable slot of the main control board.
2. Debugging
After the installation of the directional valve, it needs to be commissioned to ensure its proper operation. During commissioning, turn on and off tests are performed. In the process of opening and closing, it is necessary to observe whether the valve movement is stable and without jamming, and at the same time check the matching of the valve core and the sealing surface to ensure that it has good sealing performance.
The installation and commissioning of the directional valve is very important for its normal operation and performance, which is an important step for the directional valve to be matched in the device, I hope the above sharing can help you.
