Noise reduction mechanisms 2 are symmetrically installed on both sides of the pneumatic control valve body 1. The noise reduction mechanism 2 includes a noise reduction housing 21. A lower mounting ring 22 is symmetrically fixedly connected to the bottom of the noise reduction housing 21. A first mounting cavity 23 is opened at the top of the noise reduction housing 21. A second mounting cavity 27 is opened below the first mounting cavity 23. Limiting support blocks 4 are symmetrically fixedly connected to the inner wall of the second mounting cavity 27. The noise reduction housing 21 can effectively reduce noise.

[0021] The valve body 1 of the pneumatic control valve is provided with a connecting bracket 11 on the top, and the connecting bracket 11 is provided with a pneumatic actuator 12 on the top.

[0022] In addition, the connecting bracket 11 is installed in the second mounting cavity 27, the pneumatic actuator 12 is installed in the first mounting cavity 23, and the limiting support block 4 abuts against the bottom of the connecting brackets 11 on both sides. The limiting support block 4 is used to ensure that the noise reduction housing 21 is supported and installed on the pneumatic control valve body 1.

[0023] Meanwhile, the noise-reducing shell 21 has a glass fiber layer 211 inside, and the glass fiber material has a good sound insulation effect.

[0024] In addition, the bottom of the lower mounting ring 22 is fixedly connected to the first strap opening 221, and the noise reduction shell 21 is symmetrically provided with mounting holes 24 on both sides of the first mounting cavity 23. The mounting holes 24 are equipped with fixing parts 3, which are used to connect the two noise reduction shells 21.

[0025] Meanwhile, the noise-reducing housing 21 is symmetrically and fixedly connected to the second strap openings 25 on both sides of the second mounting cavity 27, and the noise-reducing housing 21 is provided with a plurality of heat dissipation openings 26 evenly on the housing of the second mounting cavity 27, which are used for heat dissipation.

[0026] In this embodiment, after the pneumatic control valve 1 is installed, the noise reduction mechanism 2 is installed. The lower mounting ring 22 is clamped on both sides of the valve body 1 of the pneumatic control valve, and the limiting support block 4 is pressed against the upper surface of the valve body 1 and against the bottom of the connecting bracket 11. After ensuring that the mounting hole 24 is aligned, the fixing component 3 is installed.
