DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] refer to Figure 1-2 The electromagnetic pulse valve provided in the present embodiment comprises a valve body 1 and a valve cover 2, wherein the valve body 1 is fixedly connected to the valve cover 2, a diaphragm 3 is arranged at the connection between the valve body 1 and the valve cover 2, and a positioning device 4 is also arranged on the side of the diaphragm 3 close to the valve cover 2; the positioning device 4 comprises a positioning column 41, a sliding groove 42, a limiting block 43 and a limiting sliding groove 45, one end of the positioning column 41 is fixedly connected to the diaphragm 3, the end of the positioning column 41 away from the diaphragm 3 is located in the sliding groove 42, the sliding groove 42 is arranged on the valve cover 2, a limiting sliding groove 45 is arranged on one side of the sliding groove 42, the limiting sliding groove 45 is connected to the sliding groove 42 and are perpendicular to each other, the limiting block 43 is arranged in the limiting sliding groove 45, the end of the limiting block 43 away from the sliding groove 42 is also arranged with an electric telescopic block 44, the limiting block 43 is fixedly connected to one end of the electric telescopic block 44, and a card slot is arranged on the positioning column 41.

[0025] In this embodiment, a positioning device 4 is provided on the side of the diaphragm 3 close to the valve cover 2, and a positioning column 41 is connected to the diaphragm 3. When the diaphragm 3 is opened and closed, the positioning column 41 slides in the sliding groove 42. An electric telescopic block 44 is provided to quickly and accurately control the movement of the limit block 43. The limit block 43 provided on one side of the sliding groove 42 cooperates with the card groove provided on the positioning column 41 to limit the displacement of the positioning column 41 in the sliding groove 42, so that the opening degree of the diaphragm 3 can be accurately controlled. As a key component of the electromagnetic pulse valve, the displacement of the diaphragm 3 will directly affect the The opening or closing degree of the inlet and outlet channels. In the inlet and outlet channels of the pulse valve, the gas pressure is dynamically balanced. When the diaphragm 3 is opened, the gas flow rate decreases due to the increase in channel area, but the flow rate increases, which will cause the gas pressure at the outlet to decrease. In order to maintain the pressure balance, the gas at the inlet will flow in faster, thereby keeping the pressure stable. Conversely, when the diaphragm 3 is closed, the gas pressure at the outlet increases, the gas flow rate at the inlet decreases, and the flow rate decreases. Controlling the opening and closing degree of the diaphragm 3 can accurately adjust the area of ​​the inlet and outlet channels of the electromagnetic pulse valve, thereby effectively controlling the gas flow and pressure. For specific gas flow directions, please refer to Figure 4 , Figure 4 The arrow in the middle points to the direction of gas flow. At the same time, precise control of gas flow and pressure can reduce unnecessary energy waste and reduce energy consumption.

[0026] In a further embodiment of the present invention, there are multiple positioning devices 4 , and the multiple positioning devices 4 are distributed in a circular array about the center of the diaphragm 3 .

[0027] In this embodiment, multiple positioning devices 4 are provided to ensure that the diaphragm 3 is subjected to uniform force in the circumferential direction, thereby increasing the stability and reliability of the diaphragm 3. This helps prevent the diaphragm 3 from being deformed or damaged due to uneven force; at the same time, through the synergistic effect of multiple positioning devices 4, the positioning accuracy of the diaphragm 3 can be further improved. Even if a certain positioning device 4 has a slight error, other positioning devices 4 can also compensate to ensure that the diaphragm 3 can accurately reach the predetermined position. Even if a certain positioning device 4 fails, other positioning devices 4 can still ensure the normal operation of the electromagnetic pulse valve, which reduces the failure rate of the entire electromagnetic pulse valve and improves its reliability.

[0028] In a further embodiment of the present invention, the positioning post 41 gradually becomes thinner from an end close to the diaphragm 3 to an end away from the diaphragm 3 .

[0029] In a further embodiment of the present invention, the positioning column 41 gradually becomes thinner in a step-like manner from an end close to the diaphragm 3 to an end away from the diaphragm 3 .

[0030] In this embodiment, the positioning column 41 is gradually tapered in a stepped shape. The stepped design enables the positioning column 41 to be positioned more accurately when it cooperates with the stop block 43 and the slot. The end of each step can be regarded as a positioning point. When the stop block 43 cooperates with the end of one of the steps, the stability of the positioning column 41 at a specific position can be ensured. This design helps to reduce the problem of inaccurate positioning caused by matching clearance or error, and improves the accuracy and reliability of the entire positioning device 4.

[0031] In a further embodiment of the present invention, a reinforcement block 31 is fixedly connected to one side of the diaphragm 3 close to the valve cover 2 , and one end of the positioning column 41 close to the diaphragm 3 is fixedly connected to the surface of the reinforcement block 31 .

[0032] In this embodiment, the reinforcing block 31 increases the thickness and rigidity of the local area of ​​the diaphragm 3, thereby enhancing the overall structural strength of the diaphragm 3, which helps to resist the pressure and stress generated during the operation of the electromagnetic pulse valve and reduce the risk of deformation or damage of the diaphragm 3 due to uneven or excessive force. At the same time, the reinforcing block 31, as the connection point of the positioning column 41, can provide more stable and reliable support. Since the reinforcing block 31 itself has high strength and rigidity, it can ensure that the positioning column 41 maintains a stable position in the sliding groove 42, thereby improving the positioning accuracy and stability of the entire positioning device 4.

[0033] Please refer to Figure 3 In a further embodiment of the utility model, the end of the valve cover 2 away from the valve body 1 is also connected to an electromagnetic pilot 5, and the electromagnetic pilot 5 includes a coil seat 51 and a valve core channel 52. The coil seat 51 is surrounded by the valve core channel 52, and a coil is arranged in the coil seat 51. The coil seat 51 is also filled with epoxy resin.

[0034] In this embodiment, please refer to Figure 1 The end of the valve cover 2 away from the valve body 1 is also connected to an electromagnetic pilot 5, including a coil seat 51 and a valve core channel 52. A coil is arranged in the coil seat 51 and surrounds or partially surrounds the outer surface of the valve core channel 52. The electromagnetic pilot 5 is also called a pilot device, which plays a key role in driving and controlling the electromagnetic pulse valve. When the electromagnetic pilot 5 is energized, the coil in the coil seat 51 will generate a strong magnetic force, which will attract the valve core in the valve core channel 52 and make it move quickly to the right in the valve core channel 52. This action causes the gas on the right side of the diaphragm 3 to be quickly discharged, forming a momentary low-pressure state. Under the action of the air pressure on the left side of the diaphragm 3, the diaphragm 3 will quickly move to the right, thereby opening the air outlet of the electromagnetic pulse valve. Please refer to Figure 5 Epoxy resin has good insulation properties. Filling epoxy resin between the inner wall of the electromagnetic guide 5 and the coil, wrapping the inside and outside of the coil and filling the gap between the coils, can prevent electrical short circuits between the coil in the electromagnetic guide 5 and the shell or other metal parts, and can play a good explosion-proof role. At the same time, the viscosity of epoxy resin can firmly fix the coil on the inner wall of the electromagnetic guide 5, preventing the coil from shifting or loosening under vibration or impact, and can isolate impurities such as moisture and dust in the external environment, protecting the coil from corrosion and damage.

[0035] In a further embodiment of the present invention, the valve body 1 and the valve cover 2 are fixedly connected by bolts.

[0036] Please refer to Figure 6 In a further embodiment of the present invention, the connection between the valve body 1 and the valve cover 2 is filled with epoxy resin. Specifically, since a diaphragm 3 is provided between the valve body 1 and the valve cover 2, the epoxy resin filling position is actually the joint between the valve body 1 and the diaphragm 3 and the joint between the valve cover 2 and the diaphragm 3. For the specific filling position, please refer to Figure 6 At B and C in the middle, at the same time, the gap between the bolt and the bolt hole is also filled with epoxy resin. Filling with epoxy resin can further improve the sealing of the connection. Epoxy resin has good sealing performance and can effectively prevent gas leakage, ensuring the normal operation of the electromagnetic pulse valve under high pressure or vacuum environment. At the same time, as an insulating material, epoxy resin has excellent insulating properties that help reduce the accumulation of static electricity at the connection between the valve body 1 and the valve cover 2, and can also prevent dust in the environment from accumulating at the connection between the valve body 1 and the valve cover 2 due to static electricity. In addition, epoxy resin also has excellent corrosion resistance and can protect the connection between the valve body 1 and the valve cover 2 from chemical corrosion, which is of great significance for the long-term stable operation of the electromagnetic pulse valve in harsh environments.

[0037] In a further embodiment of the present invention, the valve body 1 and the valve cover 2 are fixedly connected by epoxy resin.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
