Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, and specifically to a solenoid valve that is easy to assemble. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems 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. There are many types of solenoid valves, each playing a different role in the control system.

[0003] Most existing solenoid valves use bolts to fix the valve seat and valve cover. However, the valve core of the solenoid valve needs to be removed for cleaning periodically. Bolted solenoid valves require special tools to disassemble, and the sealing needs to be repeated after disassembly and maintenance, which has its shortcomings. Utility Model Content

[0011] Preferably, a valve core is provided in the middle of the valve body, and the valve core is controlled to move up and down by the drive device.

[0012] Preferably, the valve core interface has a valve core penetrating through its center, and the upper part of the valve core interface is attached to the lower part of the valve cover.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0024] like Figure 1-4As shown, the present invention proposes an easy-to-assemble solenoid valve, which includes a valve body 1, and the transmission end of the valve body 1 is respectively provided with a first flange 11 and a second flange 12.

[0025] A valve seat 2 is provided on the top of the valve body 1, and a protruding and through valve core interface 3 is provided in the middle of the valve seat 2.

[0026] A valve cover plate 4 is provided above the valve seat 2. A valve cover 5 that mates with the valve core interface 3 is installed at the lower part of the valve cover plate 4, and an air bladder 6 is installed in the middle. A drive device 8 passes through the middle of the valve cover plate 4.

[0027] The limiting mechanism includes a cylinder 71 located at the corner of the valve seat 2. A piston rod 72 that passes through the valve cover plate 4 is installed at the output end of the cylinder 71. A limiting rod frame 73 is formed on the upper part of the piston rod 72. A movable shaft 74 is installed at the slot of the limiting rod frame 73. A rotatable limiting rod 75 is sleeved on the movable shaft 74.

[0028] It should be noted that a valve core is provided in the middle of the valve body 1. The valve core is controlled by the up and down movement of the drive device 8. The up and down movement of the valve core controls the opening and closing of the valve body 1.

[0029] In this embodiment, when the valve core is dirty and needs to be cleaned, the limiting mechanism can be canceled. The limiting rod 75 is rotated and stored in the slot of the limiting rod frame 73 by the pivot 74. At this time, the piston rod 72 and the limiting rod frame 73 are the same as the through hole on the valve cover plate 4. The limiting is canceled by the retraction of the piston rod 72 into the cylinder 71. At this time, the valve cover plate 4 and the valve core interface 3 on the valve seat 2 can be separated, and the valve core can be taken out from the valve core interface.

[0030] During subsequent assembly, the valve core is inserted into the valve core interface. At this time, the upper part of the cylinder 71 is attached to the lower part of the valve cover plate 4. The cylinder 71 is installed at the four corners where the valve seat 2 and the valve cover plate 4 are clamped. When the limiting rod frame 73 passes through to the top of the valve cover plate 4, the limiting rod 75 rotates with the live shaft 74 installed at the bottom of the slot of the limiting rod frame 73. The contact end face between the limiting rod 75 and the valve cover plate 4 is a "cross" structure. The valve cover plate 4 is fixed by the cross limiting method, which can quickly assemble the valve cover plate 4 instead of the bolt structure.

[0031] It is understandable that the valve core is inserted through the middle of the valve core interface 3, and the upper part of the valve core interface 3 is attached to the lower part of the valve cover 5. The valve core is directly inserted into the valve core interface 3, and its guide post protrudes from the upper part of the valve body 1, establishing a connection with the drive device 8, thereby controlling the raising and lowering of the valve core.

[0032] like Figure 4 As shown, the drive device 8 passes through the combined structure of the valve core interface 3 and the valve cover 5, and the exterior of the drive device 8 is attached to the deformable surface of the airbag component 6.

[0033] It is understandable that by attaching the deformable surface of the airbag component 6 to the drive device 8, the gap at the connection is sealed, and the solenoid valve is quickly sealed.

[0034] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
