The connection structure between the valve cover and the valve body is an important part of the solenoid valve, directly affecting its sealing performance, stability, and service life.

[0003] Traditional solenoid valve bonnet connections typically use threaded connections. This makes installation and disassembly complex, requiring specialized tools and increasing maintenance costs and time.

[0004] Therefore, a valve cover connection structure and its solenoid valve are proposed. Utility Model Content

[0015] Preferably, a limiting plate is provided at the tail end of the two sets of positioning buttons, and a positioning spring is provided on the outer periphery of the positioning button, so that the limiting plate squeezes the positioning spring and the positioning button moves elastically on the inner wall of the bolt cylinder.

All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] Please see Figure 1-6 This utility model provides a valve cover connection structure, including a valve cover body 1, which is configured to mate with the connection end of the solenoid valve body 3. A connecting bolt 2 is provided on the diagonal side of the valve cover body 1.

[0033] So that the valve cover 1 is fixed to the connection end of the solenoid valve body 3 by the connecting bolt 2.

[0034] The connecting bolt 2 includes a bolt plate 21, and a bolt cylinder 22 is provided at the lower part of the bolt plate 21. Two sets of symmetrically arranged positioning bolt buttons 23 are provided at the lower part of the bolt cylinder 22.

[0035] The bolt cylinder 22 is internally provided with an extrusion member 24, which extrudes two sets of positioning bolts 23 from the inside of the bolt cylinder 22. The extrusion member 24 includes a reset groove 241 located at the bolt plate 21, an extrusion bolt 242 located inside the reset groove 241, an extrusion plate 243 located at the top of the extrusion bolt 242, and a torsion plate 244 located on the upper part of the extrusion plate 243; a limiting support rod 245 is provided on the outer periphery of the extrusion plate 243, and the limiting support rod 245 is rectangular in shape. The inner wall of the reset groove 241 is provided with a limiting groove 246 for sliding the limiting support rod 245, and the limiting groove 246 is L-shaped. A positioning groove 247 is provided at the tail end of the limiting groove 246, and the positioning groove 247 cooperates with the limiting support rod 245. A reset spring 248 is provided inside the reset groove 241, and the reset spring 248 is located on the outer periphery of the compression bolt 242, so that the compression bolt 242 and the compression plate 243 can move elastically inside the reset groove 241. The lower part of the compression bolt 242 is tapered, and the diameter of the lower part of the compression bolt 242 gradually decreases from top to bottom.

[0036] Limiting plates 231 are provided at the tail ends of the two sets of positioning pins 23, and positioning springs 25 are provided on the outer periphery of the positioning pins 23, so that the limiting plates 231 squeeze the positioning springs 25 and connect the positioning pins 23 to move elastically on the inner wall of the pin cylinder 22.

[0037] The lower part of the bolt cylinder 22 is provided with a through hole 221 for the positioning bolt 23 to pass through, and the inner wall of the bolt cylinder 22 is provided with slide rails 222 on both sides of the through hole 221 for the sliding of the limiting plate 231.

[0038] The opposing surfaces of the two sets of limiting plates 231 are provided with guide grooves 232, and the radius of the guide grooves 232 gradually decreases from top to bottom.

[0039] A solenoid valve is used to connect with a valve cover connection structure, including a valve body 3. The valve body 3 has two sets of connection holes 31 that cooperate with a plug cylinder 22 at the connection end with the valve cover. The inner wall of the connection hole 31 has a positioning hole 32 that cooperates with a positioning button 23.

[0040] The working principle of the valve cover connection structure and the solenoid valve provided by this utility model is as follows:

[0041] During installation:

[0042] Align the connecting ends of the valve cover 1 and the solenoid valve body 3, insert the plug cylinder 22 of the connecting plug 2 into the connecting hole 31 of the valve body 3, press the plug plate 21, the plug plate 21 moves inside the reset groove 241 to squeeze the reset spring 248, the reset spring 248 is compressed by force, causing the squeeze plug 242 to move downward, its conical part is inserted into the guide groove 232 between the positioning plug button 23, squeezing the positioning plug button 23, so that the positioning plug button 23 squeezes the positioning spring 25 through the limiting plate 231, and gradually expands outward.

[0043] When the limiting support rod 245 of the bolt plate 21 moves to the end of the vertical groove of the limiting slide groove 246, the positioning bolt 23 is completely squeezed out of the bolt cylinder 22 by the extrusion member 24 through the through hole 221 and enters the positioning hole 32 on the inner wall of the valve body 3 connecting hole 31, thus completing the connection and fixation between the valve cover 1 and the solenoid valve body 3.

[0044] Then, by rotating the bolt plate 21 through the torsion plate 244, the connecting limit support rod 245 is rotated to the positioning groove 247 side at the end of the limit slide groove 246. The return spring 248 elastically elongates, locking the limit support rod 245 into the positioning groove 247, thereby fixing the angle of the bolt plate 21.

[0045] During disassembly:

[0046] Press down on the bolt plate 21, then rotate the torsion plate 244 in the opposite direction. The return spring 248 is weakened by the force and stretches elastically, causing the squeeze bolt 242 to rise upward and return to the initial position.

[0047] The conical part of the compression bolt 242 gradually disengages from the positioning bolt 23, and the positioning bolt 23 retracts inward under the action of the positioning spring 25, exiting the positioning hole 32.

[0048] When the positioning button 23 is completely withdrawn from the positioning hole 32, the connection between the connecting bolt 2 and the valve body 3 is released.

[0049] At this point, the connecting bolt can be easily pulled out of the connecting hole in the valve body to complete the disassembly of the valve cover.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
