The electric butterfly valve is a butterfly valve that is filled with compressed air in a retractable closed container and uses air elasticity. It can realize support, buffering, braking, height adjustment, angle adjustment and other functions. This product does not need external power to work. It has stable lifting force and can stretch freely (the lockable air butterfly valve can be positioned at will). It has a wide range of applications, and the following points should be noted during installation:
1. The piston rod of the air butterfly valve must be installed in the downward position instead of upside down, so as to reduce friction and ensure good damping quality and cushioning performance.
2. Determining the installation position of the fulcrum is the guarantee for the correct operation of the air butterfly valve. The air butterfly valve must be installed in the correct way, that is, when it is closed, let it move over the center line of the structure, otherwise, the air butterfly valve will often automatically push the door open.
3. The air butterfly valve shall not be subject to tilt force or transverse force during operation. It shall not be used as handrail.
4. In order to ensure the reliability of sealing, the piston rod surface shall not be damaged, and paint and chemicals shall be applied on the piston rod strictly. It is also not allowed to install the air butterfly valve at the required position before spraying and painting.
5. The air butterfly valve is a high-pressure product, which is strictly and randomly analyzed, baked and bumped.
6. The piston rod of the air butterfly valve rotates strictly to the left. If you need to adjust the valve direction, you can only turn it to the right.
7. Operating ambient temperature: - 35 ℃ -+70 ℃. (. Custom made 80 ℃)
8. When installing the connection point, it should rotate flexibly without jamming.
9. The size should be reasonable, the force should be appropriate, and the stroke size of the piston rod should have an 8mm margin.
