Description

Technical Field

[0001] This invention relates to the field of solenoid valve technology, and more specifically, to a high-vacuum solenoid valve. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. Currently, existing high-vacuum solenoid valves generally have a single integrated structure for the valve body and connections. This complexity makes installation and disassembly cumbersome, hindering internal processing of the valve body and connections. Furthermore, vibrations generated during operation can cause the iron core to shift, leading to seal failure.

[0003] Therefore, it is necessary to provide a high-vacuum solenoid valve to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a high-vacuum solenoid valve that is easy to maintain and has strong structural stability.

[0005] The technical solution adopted by this application to solve its technical problem is: a high vacuum solenoid valve, including a valve body, a B port connected to a flange on one side of the valve body, a B through groove provided inside the B port, an A port connected to a flange on the other side of the valve body, an A through groove provided inside the A port, a protective housing threaded to the upper end of the valve body, a coil provided inside the protective housing, and a DIN terminal box threaded to the side end of the protective housing.

[0006] Furthermore, a moving iron core is provided on the inner side of the coil, a stationary iron core is provided at the top of the moving iron core, and a plug is fixedly installed at the bottom of the moving iron core, the plug being located at the upper end of the A-slot opening.

[0007] Furthermore, the protective housing is divided into two parts. A port post is fixedly installed at the front end of the protective housing, and a threaded post is fixedly installed on the outer side of the port post.

[0008] Furthermore, a threaded thread is fixedly installed on the upper end of the valve body, and the threaded thread is threadedly connected to the threaded post.

[0009] Furthermore, a protective gasket is fixedly installed on the inner side of the protective housing.

[0010] Furthermore, a valve seat is fixedly installed at the bottom end of the valve body, and threaded holes are provided on both sides of the valve seat.

[0011] The beneficial effects of this utility model are: the protective housing adopts a split threaded connection, and the coil can be quickly disassembled and replaced by the threaded post and threaded thread, thereby reducing maintenance costs. The protective gasket on the inner side of the protective housing plays a role in shockproofing and dustproofing the coil. The threaded holes on both sides of the valve seat facilitate secure installation and reduce the impact of pipeline vibration. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.

[0020] like Figure 1-3As shown, this application provides a high vacuum solenoid valve, including a valve body 1. A flange on one side of the valve body 1 is connected to a port B 3, and a through groove B 7 is provided inside the port B 3. A flange on the other side of the valve body 1 is connected to a port A 4, and a through groove A 5 is provided inside the port A 4. A protective housing 2 is threadedly connected to the upper end of the valve body 1. A coil 6 is provided inside the protective housing 2. A DIN terminal box 9 is threadedly connected to the side end of the protective housing 2.

[0021] A moving iron core 11 is provided on the inner side of the coil 6, a stationary iron core 10 is provided at the top of the moving iron core 11, and a plug 15 is fixedly installed at the bottom of the moving iron core 11. The plug 15 is located at the upper end of the slot of the A through groove 5.

[0022] The protective housing 2 is divided into two parts. A port post 16 is fixedly installed at the front end of the protective housing 2, and a threaded post 12 is fixedly installed on the outside of the port post 16.

[0023] A threaded thread 14 is fixedly installed on the upper end of the valve body 1, and the threaded thread 14 is threadedly connected to the threaded post 12.

[0024] A protective gasket 13 is fixedly installed on the inner side of the protective housing 2.

[0025] A valve seat 8 is fixedly installed at the bottom of the valve body 1, and threaded holes are provided on both sides of the valve seat 8.

[0026] Specifically, when coil 6 is not energized, the moving iron core 11 falls under the influence of gravity, and then the plug 15 at the bottom presses against the opening of slot A 5, blocking the passage between port A 4 and port B 3. The valve is in the closed state, thereby ensuring a vacuum seal. After the valve is closed, the vacuum solenoid valve is energized, and the current is connected to coil 6 through DIN terminal box 9, generating an electromagnetic field. The moving iron core 11 is attracted upward by magnetic force, causing the plug 15 to disengage from the opening of slot A 5. Slot A 5 and slot B 7 are connected, and the medium flows from port A 4 to port B 3, opening the valve.

[0027] The protective housing 2 adopts a split threaded connection. The coil 6 can be quickly disassembled and replaced by the threaded post 12 and the threaded buckle 14 to reduce maintenance costs. The protective gasket 13 on the inner side of the protective housing 2 plays a role in shockproofing and dustproofing the coil 6. The threaded holes on both sides of the valve seat 8 facilitate secure installation and reduce the impact of pipeline vibration.
