[0032] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are contradictory.

[0033] Combine the following Figure 1 and Figure 2 The utility model is described as a muffler for a solenoid valve. The muffler for a solenoid valve comprises: a sealing shell 1 and a muffler pipe 2.

[0034] The sealed shell 1 serves as the shell of the silencer and is a tubular structure with openings at both ends and a sealed outer wall. The silencer pipe 2 can be inserted into the sealed shell 1 through the openings at both ends, and due to the sealed structure of its outer wall, it can effectively shield noise.

[0035] The silencer pipe fitting 2 is at least partially sealed and inserted into the interior of the sealed shell 1, one end of the silencer pipe fitting 2 is exposed to the sealed shell 1, and the portion of the silencer pipe fitting 2 exposed to the sealed shell 1 is formed with a connecting portion, which is used to connect with the solenoid valve; a diffusion guide structure 3 is provided inside the silencer pipe fitting 2, and the diffusion guide structure 3 is used to guide the airflow to diffuse along the circumferential direction of the silencer pipe fitting 2; a plurality of through holes 4 are formed on the side wall of the silencer pipe fitting 2, which are used to guide the airflow to form a vortex.

[0036] Specifically, in this embodiment, the silencer pipe 2 is also a tubular structure with openings at both ends. One end of the silencer pipe 2 is exposed to the sealed housing 1, and a connecting portion is formed on the end, through which the connection portion can be connected to the solenoid valve. The gas discharged from the solenoid valve enters the silencer pipe 2 through the opening at one end of the connecting portion. The silencer pipe 2 has the function of guiding the airflow, so that impurities are effectively discharged.

[0037] Since a diffusion guide structure 3 is provided inside the silencer pipe fitting 2, the airflow can be guided to diffuse from the center of the silencer pipe fitting 2 to the circumference of the silencer pipe fitting 2, and the gas has a wider flow space, thereby gradually slowing down the gas flow rate, because the flow rate of the same amount of gas will inevitably decrease in a larger space, thereby playing a role in initially reducing the flow rate; at the same time, this gradually expanding space can also have a certain dispersion and reduction effect on the pressure.

[0038] Through holes 4 are formed on the side wall (i.e., the tube wall) of the muffler pipe 2, which have the effect of dispersing and interfering with the propagation of sound waves. When the gas flows through these through holes 4, a part of the gas will enter the through holes 4 to form vortices, which not only consumes the energy of the gas and further reduces the flow rate, but also these vortices and complex airflow movements can effectively absorb the energy of sound waves and reduce noise. The inner wall of the muffler pipe 2 with through holes 4 increases the contact area and friction between the gas and the structure, further buffers the pressure, and enables the pressure to be more effectively weakened.

[0039] In addition, when the airflow passes through the silencer pipe 2, its diffusion and guide structure 3 and the through hole 4 design will cause the airflow to produce a certain swirl or change the flow direction. In this process, impurities in the airflow will collide with the inner wall of the silencer pipe 2 or be affected by centrifugal force due to inertia and other reasons, and will be more easily deposited or separated, thereby achieving effective discharge of impurities. This can not only ensure the smooth passage of the airflow, but also reduce the adverse effects of impurities on subsequent links.

[0040] In summary, through the synergistic effect of the diffusion guide structure 3 and the silencer pipe 2 with the through hole 4, the gas pressure generated by the exhaust of the solenoid valve can be effectively weakened and absorbed, and the gas flow rate can be reduced, thereby achieving beneficial effects such as reducing noise, optimizing the working environment and protecting related equipment.

[0041] The utility model provides a silencer for an electromagnetic valve, which comprises: a sealed shell 1 and a silencer pipe 2; the silencer pipe 2 is at least partially sealed and inserted into the interior of the sealed shell 1, one end of the silencer pipe 2 is exposed to the sealed shell 1, and a connecting portion is formed on the portion of the silencer pipe 2 exposed to the sealed shell 1, and the connecting portion is used to connect with the electromagnetic valve; a diffusion and guide structure 3 is provided inside the silencer pipe 2, and the diffusion and guide structure 3 is used to guide the airflow to diffuse along the circumferential direction of the silencer pipe 2; a plurality of through holes 4 are formed on the side wall of the silencer pipe 2, which are used to guide the airflow to form a vortex. The utility model provides a muffler for a solenoid valve, in which a diffusion guide structure 3 is provided inside the muffler pipe 2, which can guide the airflow to diffuse from the center of the muffler pipe 2 to the circumference of the muffler pipe 2, thereby gradually slowing down the gas flow rate, and also buffering the pressure, so that the pressure can be weakened more effectively; through holes 4 are processed and formed on the side wall of the muffler pipe 2, and when the gas flows through these through holes 4, a part of the gas will enter the through holes 4 to form vortices, which not only consumes the energy of the gas and further reduces the flow rate, but also further buffers the pressure, so that the pressure can be weakened more effectively. It can be seen that the utility model provides a muffler for a solenoid valve, through the synergistic effect of the diffusion guide structure 3 and the muffler pipe 2 with the through holes 4, can effectively weaken and absorb the gas pressure generated by the exhaust of the solenoid valve, reduce the gas flow rate, and thus achieve the beneficial effects of reducing noise, optimizing the working environment and protecting related equipment.

In addition, a plurality of diffusion ports are arranged along the axial direction of the silencer pipe 2, which can resist and absorb high-pressure gas layer by layer, and gradually weaken the gas pressure and flow rate.

[0043] In one embodiment of the present invention, a plurality of through holes 4 are arranged along the axial direction of the muffler pipe 2, a plurality of through holes 4 are arranged along the circumferential direction of the muffler pipe 2, and the through holes 4 are arranged perpendicular to the wall surface of the muffler pipe 2.

[0044] In one embodiment of the utility model, the connection portion includes: a thread structure 5, which is provided at one end of the silencer pipe 2 exposed to the sealed housing 1. Specifically, the thread structure 5 is a threaded structure provided on the outer wall of the silencer pipe 2, and is connected to the solenoid valve through the threaded structure, so that the silencer for the solenoid valve is stably installed on the solenoid valve.

Preferably, the sound absorbing structure 6 includes sound absorbing cotton, which is disposed between the inner wall of the sealed housing 1 and the outer wall of the muffler pipe 2 to effectively shield and absorb noise. It should be understood that the sound absorbing structure 6 can be made of other absorbent materials.

[0046] In one embodiment of the utility model, the silencer for the solenoid valve further includes: a first sealing cover 7 and a second sealing cover 8. The first sealing cover 7 is sealingly arranged at one end of the sealing shell 1, and the sound absorbing structure 6 and the silencer pipe 2 are sealed and packaged inside the sealing shell 1; the second sealing cover 8 is sealingly arranged at the other end of the sealing shell 1, and the sound absorbing structure 6 and the silencer pipe 2 are sealed and packaged inside the sealing shell 1.
