Thereby improving the noise reduction effect and reducing the noise generated by the fluid with reduced flow rate, thereby achieving a noise reduction effect. However, the device only reduces the generation of noise from the inside, and cannot further reduce the propagation of noise from the outside, and the noise reduction effect is not high enough. Utility Model Content

[0008] Preferably, the coating film includes a waterproof rubber film and wear-resistant cloth. The waterproof rubber film is coated on the surface of the solenoid valve body, and the outer side of the waterproof rubber film is compounded with wear-resistant cloth, and the outer wall of the wear-resistant cloth contacts the damping particles.

[0009] Preferably, the inflation structure includes a sealing cover and an air port. The top of the shell is fixedly provided with an air port for inflation and deflation, and the upper end of the air port is threadedly connected to the sealing cover.

[0026] The front end of the gusset plate 3 is integrally formed with an inclined plate that is tilted upward to facilitate lifting the front end of the gusset plate 3.

[0027] Working principle: After the sound wave energy is transmitted to the damping particles 10, the energy is converted into internal energy and released through the mutual friction when the damping particles 10 vibrate, effectively dissipating the sound wave energy and reducing noise; air is injected through the air port 7 to make the coating film 11 fit the solenoid valve body 2, and the sound insulation cotton 8 further insulates the sound and supports the partition layer 9.
