Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve silencing, and more specifically, to a muffler used for controlling the release of gas noise from an electromagnetic valve. Background Art

[0002] A solenoid valve is a device that uses electromagnetic force to control the flow of media (such as gas, liquid, powder, etc.). It is usually composed of a solenoid coil, a valve body, a valve core, and a seal. When the solenoid valve is working, the noise is generated when the valve is opened or closed to release the gas. A small amount of moisture in the gas will remain in the solenoid valve, and the standard silencer terminal cannot discharge this moisture. In this case, the life of the solenoid valve and the cylinder will be reduced, and the working efficiency will be reduced.

[0003] After searching, the Chinese patent with announcement number CN217977705U discloses an improved muffler for a solenoid valve. The muffler in the utility model is installed on the solenoid valve. The absorption material of the shell can not only absorb noise, but also absorb moisture in the gas. In addition, due to the barrier effect of the absorption material, dust in the external environment is not easy to enter the solenoid valve. It is only necessary to replace the absorption material or the muffler regularly.

[0004] When the above patent is in use, the chamber is filled with absorbent material, and the absorbent material is composed of one or more of fiber, cotton wool, and sponge. However, when the gas is discharged, it has a large impact force, which can easily flush the absorbent material out of the predetermined position, resulting in poor use effect. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a muffler for controlling the release of air noise by a solenoid valve, comprising a box body, a top side of the box body being fixedly connected to a plate-type muffler main body, an inner bottom end of the box body being fixedly connected to a storage frame, a noise reduction buffer assembly being provided on the storage frame, the noise reduction buffer assembly comprising a second threaded plug rod, a connecting plate, an extrusion sleeve, a water absorbing layer, a sound absorbing layer and a buffer layer, the bottom end of the second threaded plug rod passes through the box body and the storage frame and is fixedly connected to the connecting plate, the extrusion sleeve is movably mounted on the second threaded plug rod, the water absorbing layer, the sound absorbing layer and the buffer layer are all located in the storage frame, and the water absorbing layer, the sound absorbing layer and the buffer layer are all movably mounted on the second threaded plug rod.

[0007] Furthermore, a sealing ring is movably provided at the bottom of the buffer layer, and the bottom end of the sealing ring is in contact with the connecting plate.

[0008] It can be seen that in the above technical solution, the sealing ring can improve the sealing between the connecting plate and the storage frame.

[0009] Furthermore, an extrusion frame is movably provided on the top of the water absorbing layer, and the extrusion frame is movably sleeved on the second threaded insertion rod.

[0010] It can be seen that in the above technical solution, the extrusion frame extrudes and limits the water absorbing layer.

[0011] Furthermore, a sealing gasket is movably provided on the top of the extrusion frame, and the sealing gasket is movably sleeved on the second threaded rod.

[0012] It can be seen that in the above technical solution, the sealing gasket can improve the sealing between the extrusion rack and the storage frame.

[0013] Furthermore, a first partition is fixedly connected to one side of the interior of the box body, and two second partitions are fixedly connected to the interior of the plate-type muffler body.

[0014] It can be seen that in the above technical solution, the first baffle and two second baffles are provided to facilitate the guidance of the gas.

[0015] Furthermore, a filter assembly is provided on the main body of the plate-type muffler, and the filter assembly includes a filter plate, a first threaded insert rod and two threaded sleeves.

[0016] Furthermore, one end of the first threaded rod passes through the plate-type muffler body and the filter plate, and the two threaded sleeves are movably sleeved on the first threaded rod.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model seals the high-speed eddy current noise generated by the Reynolds effect and performs acoustic control through the principles of two-chamber silencers (box and storage frame) and one-piece silencer (piece silencer body). At the same time, the material selection of the box, storage frame and piece silencer body needs to meet the requirements of the noise spectrum, so that it has good sound absorption and noise reduction capabilities, and the basis for the calculation of the sound insulation is the NR curve of the target control value. The calculation result of the silencer sound insulation is the sum of the calculation results of the combined sound insulation. The buffer layer and the sealing gasket buffer the incoming gas, rotate the extrusion sleeve and keep it away from the second threaded plug rod, so as to release the fixation between the second threaded plug rod and the box, move the second threaded plug rod downward and move the water absorption layer, the sound absorption layer and the buffer layer into the storage frame, and replace the water absorption layer, the sound absorption layer and the buffer layer according to the needs of noise reduction and water absorption. The structure is simple and the use effect is good;

[0019] 2. The utility model fixes the filter plate by placing the filter plate into the main body of the plate-type silencer, and then inserting the first threaded rod into the filter plate, and limiting the first threaded rod by two threaded sleeves. Similarly, the filter plate can be disassembled and cleaned, and dust and other debris can be filtered through the filter plate. The utility model has a simple structure and is easy to use.
