Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic valve silencing technology, and more specifically, to a dedicated silencer for electromagnetic valves. Background Technology
[0002] A solenoid valve is an industrial device controlled by electromagnetic force, mainly used to control the on / off state and flow direction of fluids. It has wide applications in many fields such as industrial automation, HVAC, automobiles, and home appliances. A double solenoid valve is a device composed of two solenoid valves combined together. When a solenoid valve is working, especially during exhaust, the rapid discharge of gas from a high-pressure chamber to a low-pressure environment generates strong aerodynamic noise. A silencer, through structures such as an expansion chamber, a resonant chamber, and sound-absorbing materials, continuously changes the flow velocity and direction of the gas during exhaust, consuming the gas's energy and thus reducing the noise generated during gas discharge.
[0003] Existing double solenoid valves are generally equipped with a throttle valve, which controls the fluid flow rate. The exhaust port of the double solenoid valve will generate high-intensity aerodynamic noise. Generally, a single-layer silencer is used to silence the double solenoid valve. However, a single-layer silencer is difficult to effectively handle noise of all frequencies. Its suppression effect on high-frequency or low-frequency noise is weak, resulting in an unsatisfactory overall noise reduction effect. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a silencer for solenoid valves, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a silencer for a solenoid valve, comprising a solenoid valve body, a silencer horn opening on one side of the solenoid valve body, and a silencer mechanism on one side of the silencer horn opening. The silencer mechanism includes a first silencer component and a second silencer component. The first silencer component includes a first silencer frame, a side plate, and two first baffles. The side plate is fixedly sleeved on the outside of the first silencer frame, and the two first baffles are fixedly installed on the inside side of the first silencer frame. The second silencer component includes a second silencer frame, two connecting blocks, and two second baffles. The two connecting blocks are fixedly installed on one side of the second silencer frame, and the two second baffles are fixedly installed on the inside side of the second silencer frame.
[0006] Furthermore, the first muffler frame has a first exhaust port on both the front and rear sides, and the area of the first exhaust port is twice that of the muffler horn.
[0007] It can be seen that the above technical solution achieves the first reduction in airflow speed, and the speed is reduced to half of the original speed.
[0008] Furthermore, two second exhaust ports are provided on one side of the second muffler frame, and the area of the second exhaust port is twice that of the first exhaust port.
[0009] It can be seen that in the above technical solution, the airflow speed is reduced a second time, and the airflow speed becomes one-quarter of the original speed.
[0010] Furthermore, one side of both first baffles and both second baffles is curved.
[0011] As can be seen, in the above technical solution, the arc-shaped baffle can guide the airflow to smoothly turn along the arc trajectory by virtue of its unique curved surface. In this way, the originally turbulent airflow is sorted out, the airflow velocity distribution is more uniform, and the generation of vortices and turbulence is reduced, so that the released airflow can flow more stably and efficiently in the anechoic chamber.
[0012] Furthermore, the bottom end of the second sound-absorbing frame is provided with multiple drainage grooves.
[0013] It can be seen that the above technical solution ensures that the condensate from the purge gas can be discharged in a timely manner.
[0014] Furthermore, a metal mesh is fixedly embedded inside each of the two second exhaust ports, and the opening ratio of the metal mesh is 85%.
[0015] It can be seen that the above technical solution is designed to prevent pollutants from entering the muffler opening.
[0016] Furthermore, the solenoid valve body, side plate, and two connecting blocks are fixed together by bolts, and a gasket is movably provided on one side of the side plate.
[0017] It can be seen that the above technical solution aims to improve the sealing performance between the first and second silencing frames.
[0018] Furthermore, the first silencing frame, side plate, two first baffles, second silencing frame, two connecting blocks, and two second baffles are all composed of a support layer, a damping layer, a sound-absorbing layer, and a protective layer.
[0019] The technical effects and advantages of this utility model are as follows:
[0020] 1. In this utility model, the venting gas inside the solenoid valve body enters the first silencer frame through the silencer horn, and the venting gas inside the first silencer frame enters the interior of the second silencer frame through the first exhaust port, which can achieve the first reduction of airflow speed. Finally, the venting gas exits the second silencer frame through the second exhaust port, which can achieve the second reduction of airflow speed. The structure is simple, with double-layer silencing, which effectively improves the overall silencing effect.
[0021] 2. This utility model involves fitting a first silencing frame onto the solenoid valve body, with one side of the side plate in contact with the solenoid valve body. Then, a gasket is fitted onto the side plate, followed by fitting a second silencing frame onto the first silencing frame, with both connecting blocks in contact with the gasket. Finally, bolts are used to fix the solenoid valve body, the first silencing frame, and the second silencing frame together. Similarly, the first and second silencing frames can be disassembled. The structure is simple and easy to use. Attached Figure Description

The side plate 402 is fixedly sleeved on the outside of the first silencer frame 401, and the two first baffles 403 are fixedly installed on the inside side of the first silencer frame 401. The second silencer component 5 includes a second silencer frame 501, two connecting blocks 502, and two second baffles 503. The two connecting blocks 502 are fixedly installed on one side of the second silencer frame 501, and the two second baffles 503 are fixedly installed on the inside side of the second silencer frame 501.
[0031] Furthermore, the first muffler frame 401 has first exhaust ports on both the front and rear sides, and the area of the first exhaust port is twice that of the muffler horn 2. The second muffler frame 501 has two second exhaust ports on one side, and the area of the second exhaust port is twice that of the first exhaust port. The two first baffles 403 and the two second baffles 503 are all arc-shaped on one side.
[0032] Furthermore, the bottom of the second silencer frame 501 is provided with multiple drainage grooves 504 to ensure that the condensate from the venting gas can be discharged in a timely manner.
[0033] Furthermore, metal mesh 3 is fixedly embedded inside both second exhaust ports, and the opening ratio of metal mesh 3 is 85%. Metal mesh 3 can prevent contaminants from entering the muffler horn port 2.
[0034] Furthermore, the solenoid valve body 1, the side plate 402, and the two connecting blocks 502 are fixed together by bolts, and a gasket 6 is movably provided on one side of the side plate 402.
[0035] Furthermore, the first silencing frame 401, the side plate 402, the two first baffles 403, the second silencing frame 501, the two connecting blocks 502, and the two second baffles 503 are all composed of a support layer, a damping layer, a sound-absorbing layer, and a protective layer.
[0036] The first silencer frame 401 is fitted onto the solenoid valve body 1, with one side of the side plate 402 in contact with the solenoid valve body 1. Then, a gasket 6 is fitted onto the side plate 402. The gasket 6 can improve the sealing between the first silencer frame 401 and the second silencer frame 501.

Similarly, the first silencer frame 401 and the second silencer frame 501 can be disassembled. The structure is simple and easy to use.
[0037] The usage method of this embodiment is as follows:
[0038] In operation, the venting gas inside the solenoid valve body 1 passes through the muffler horn 2 and enters the first muffler frame 401. The venting gas inside the first muffler frame 401 then enters the interior of the second muffler frame 501 through the first exhaust port. Since the area of the first exhaust port is twice that of the muffler horn 2, the airflow velocity is reduced to half its original value as the venting gas passes through the first exhaust port. Finally, the venting gas exits the second muffler frame 501 through the second exhaust port. Since the area of the second exhaust port is twice that of the first exhaust port, the venting gas can... The system achieves a second reduction in airflow velocity, reducing it to one-quarter of its original speed. Its simple structure and double-layered sound absorption effectively improve the overall noise reduction effect. The first baffle 403 and the second baffle 503 guide the airflow. When the released airflow reaches the right-angle region, the curved baffle, with its unique curved surface, guides the airflow to smoothly change direction along the curved trajectory. In this way, the originally turbulent airflow is streamlined, the airflow velocity distribution becomes more uniform, and the generation of vortices and turbulence is reduced, allowing the released airflow to flow more stably and efficiently within the sound-absorbing chamber.
