Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a two-position five-way solenoid valve body. Background Technique

[0002] The two-position five-way solenoid valve is a commonly used pneumatic control component. Its structure includes two working positions and five interfaces. Different from ordinary solenoid valves with only two interfaces, the two-position five-way solenoid valve has three air vents and two exhaust ports, which can control the flow direction of different gases or liquids and realize the complex interlocking control of multiple pneumatic components. The working principle of the two-position five-way solenoid valve is similar to that of ordinary solenoid valves, which is based on the action of an electromagnet to realize the opening and closing of the valve body. When the electromagnet is energized, a magnetic field will be generated, causing the valve core to move to the corresponding working position under the action of the magnetic force, thereby changing the connection relationship between the air vents and the exhaust ports. Through different combinations of working positions, different gas or liquid flow directions can be controlled to meet the requirements of complex interlocking logic control. The gas or liquid flowing in the existing two-position five-way solenoid valve body may contain impurities. The entry of impurities into the valve body may cause the piston and valve in the solenoid valve to get stuck or damaged, affecting the service life of the two-position five-way solenoid valve body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1:

[0020] As Figures 1 - 3 shown, the present utility model provides a two-position five-way solenoid valve body, including a valve body 1. A control spool module 2 and a protective housing 5 are fixedly connected to the outer surface of the valve body 1. Air holes 3 are provided on the outer surface of the valve body 1, and a filtering mechanism 4 is provided inside the air holes 3. A cooling fan 6 is fixedly connected to the outer surface of the protective housing 5. The filtering mechanism 4 includes a first connection shell 401 and a second connection shell 402. A fixed seat 407 is fixedly connected to the inner surface of the first connection shell 401. A connection frame 408 is threadedly connected to the inner surface of the fixed seat 407. A filter net 409 and a connection rod 410 are fixedly connected to the inner surface of the connection frame 408. An installation end 403 is provided at the top of the second connection shell 402.

[0021] Specifically, the control spool module 2 is arranged in the inner cavity of the protective housing 5, and the number of the air holes 3 is five.

[0022] Specifically, the outer surface of the first connection shell 401 is threadedly connected to the inner surface of the air hole 3, the inner surface of the second connection shell 402 is threadedly connected to the outer surface of the first connection shell 401, and the first connection shell 401 is arranged directly below the second connection shell 402.

[0023] Specifically, a fixing plate 404 is fixedly connected to the inner surface of the second connection shell 402, and a first sealing gasket 405 is fixedly connected to the lower surface of the fixing plate 404.

[0024] Specifically, a second sealing gasket 406 is fixedly connected to the top of the first connection shell 401, and the second sealing gasket 406 is arranged directly below the first sealing gasket 405.

[0026] The working principle and beneficial effects of the above embodiments.

[0027] In use, the filtering mechanism 4 is installed in the air hole 3 through the first connecting shell 401, and then connected to the air source through the mounting end 403 at the top of the second connecting shell 402. When the valve body 1 works, gas or liquid enters the second connecting shell 402 from the mounting end 403, passes through the filter net 409, and is introduced into the air hole 3 from the bottom end of the first connecting shell 401. Most of the impurities contained in the flowing medium are blocked by the filter net 409, minimizing the impurities entering the interior of the valve body 1. During the operation of the valve body 1, heat is generated inside the control spool module 2. The heat dissipation fan 6 can increase the air flow around the control spool module 2, thereby improving the heat dissipation efficiency of the control spool module 2 to prevent the electromagnet inside the control spool module 2 from overheating and being damaged. The filtering mechanism 4 is regularly disassembled, and the second connecting shell 402 is disassembled from the first connecting shell 401. Hold the connecting rod 410 and drive the connecting frame 408 to rotate, so that the connecting frame 408 is disassembled from the fixed seat 407, facilitating the cleaning of the accumulated impurities in the filter net 409, the first connecting shell 401, and the second connecting shell 402, and facilitating the continuous use of the filtering mechanism 4. With the provided first gasket 405 and second gasket 406, when the first connecting shell 401 and the second connecting shell 402 are installed together, the first gasket 405 and the second gasket 406 are pressed together, ensuring good sealing between the first connecting shell 401 and the second connecting shell 402.
