The actuator and adjustment mechanism of the pneumatic actuator are unified. The actuators are available in piston and fork frame versions. Long piston stroke, suitable for occasions with high thrust requirements. The diaphragm travel is small and can only drive the valve stem directly. Through the above introduction, we have a certain understanding of pneumatic actuators. Let's talk about the installation and use precautions of
pneumatic actuators:
1. The pipes of the
pneumatic actuator must be cleaned. If there are impurities in the medium, install a filter valve in front of the valve pipe.
2. If a solenoid valve is installed, please pay attention to the safety of the connection.
3. Ensure the space required for maintenance and removal of parts during installation.
4. The axial clearance between the valve device and the pneumatic valve should not be less than 1~2mm.
5. The bolt connecting the pneumatic valve shall not be less than 8.8.
6. When used with an open valve stem, check whether the extension of the valve stem is the same length as the valve stem sleeve.
7. When it needs to be disassembled, the manual handwheel should be rotated several times, and then the pneumatic valve is slightly opened.
8. Sealing covers, seals and explosion-proof surfaces used for installation, disassembly and debugging of electrical equipment shall not be damaged. The explosion-proof surface should be coated with anti-rust oil, and the electrical cover should be tightly closed. Avoid rain or moisture.
9. The window cannot collide with hard objects.
10. Check whether the type and parameters of the pneumatic actuator meet the installation requirements and technical requirements.
11. Check the cylinder and position indicator of the valve to make sure there is no damage.
12. When soldering connections are required, avoid high temperature transfer to solder, etc.
13. If a solenoid valve is installed, please pay attention to the safety of the connection.
14. When the pneumatic valve is not used frequently, it should be checked, maintained and operated regularly. Doctors recommend that they have surgery at least once a month for no more than 10 minutes.
Through the above description, we can fully prepare and check the pneumatic actuator before installation, carefully study the manual of the
pneumatic actuator, pay attention to the safety during the installation process, avoid omissions, and reduce unnecessary problems during the installation process.
