How to adjust the pressure of the cylinder pressure regulating valve

Generally, triple components are used, in which there is a pressure regulating valve to control the pressure of the pipeline. The pressure is different. Cylinder The output force is also different.

(1) Before the pneumatic valve is installed and used, the valve must be inspected before installation and the switch operation test is carried out. It can only be installed and used under normal operating conditions.

(2) The pneumatic valve should be installed so that the valve and the pipeline flange are as concentric as possible and supported and fixed. The ball valve cannot be subjected to other external forces to avoid damage to the middle seal of the valve and deformation of the valve. This may cause the valve switch to malfunction and the valve to be damaged and unable to be used.

(3) Ensure that the power air source provided by the balloon valve and pneumatic components must be clean and free of oil and water as much as possible. Cleanliness should be less than 0.4 microns.

(4) Before connecting to the gas source, the gas supply pipeline, gas source interface, switch and other devices must be cleaned to prevent dirt and sediment from being brought in due to unclean pipelines Rush into the pneumatic actuator unit and cause malfunction.

(5) Copper tubes or nylon tubes can be used to connect pneumatic actuators, solenoid valves, positioners, filters, pressure reducing valves, etc. to prevent dust and reduce To reduce noise, a muffler or muffler throttle valve should be installed at the exhaust port.

(6) After installation, the pneumatic valve should be tested, the pneumatic actuator should be pressurized to the rated value, the pressure is 0.4~0.7mpa, and the pneumatic ball valve should be tested on and off. , observe the opening and closing of the valve. It should rotate flexibly without any jamming. If there is any jamming in the switch, you can increase the air pressure and switch the valve repeatedly to adjust it to a flexible position.

(7) When installing and debugging the switch-type pneumatic valve, first use a manual device (manual button on the solenoid valve) for debugging. After the operation is normal, power on for debugging.

(8) The pneumatic valve should be regularly maintained at the rotating part of the valve stem, and should be refueled (engine oil) once every three months. Regularly drain and drain the pneumatic actuator unit and the used air filter. Under normal circumstances, it should be inspected once every six months and overhauled once a year.

How to connect the cylinder pressure regulating valve

These three devices will have threaded interfaces of different sizes. According to the pipes used, special threaded joints can be installed to connect them. For example, commonly used PU air pipes can be quickly connected through threaded quick-in connectors.

The general connection sequence is that the air source is connected to the "pressure regulating valve" and then to the "solenoid valve" and finally to the "cylinder". Pay attention to the specifications of the solenoid valve. The pilot solenoid valve has a working pressure range. If the pressure is small, you may need to put the "solenoid valve" in the front and the "pressure regulating valve" in the middle, but in this way the "pressure regulating valve" will always be impacted by air pressure. , life span is affected.
