Description

Technical Field

[0001] The utility model relates to the technical field of combined solenoid valves, and more specifically, to a combined solenoid valve. Background Art

[0002] In the existing technology, there are some inconveniences in the assembly process of the combined solenoid valve. Since the combined solenoid valve is composed of multiple components, including the valve body, valve core, solenoid coil, etc., these components need to be accurately combined together to ensure the normal operation of the solenoid valve. However, in the existing equipment, the connection between these components is often a fixed connection, that is, once the assembly is completed, the relative position between the components can no longer be adjusted. This fixed connection method brings some problems in the trial installation stage.

[0003] Trial installation is an important part of the assembly process of combined solenoid valves. It allows engineers to conduct preliminary tests and adjustments to the solenoid valves before finalizing the position of the components. During this process, engineers may need to adjust the position of the components several times to optimize the performance of the solenoid valve. However, since the existing equipment can only be fixed, this means that each adjustment requires the solenoid valve to be disassembled and reassembled, which not only increases the time for trial installation, but also increases the complexity of assembly and the possibility of errors.

The base 1 is mounted on an external device, the valve body 2 is fitted on the base 1, and a mounting mechanism is arranged on the valve body 2. The mounting mechanism comprises a fixing plate 3, a fixing rod 4, a positioning rod 5, a fixing sleeve 6, a clamping mechanism, a fixing disk 7, a limiting sleeve 8 and an insertion rod 9.

A plurality of mounting mechanisms are provided, and the plurality of mounting mechanisms are respectively installed on the base 1 and the valve body 2.

[0029] In this embodiment, when the valve body 2 needs to be pre-fixed, the positioning rod 5 on the fixing rod 4 passes through the fixing plate 3, and then the fixing sleeve 6 is slidably connected to the positioning rod 5, and each telescopic hole 15 is slidably connected to the push rod 14, and the push rod 14 is abutted in the spiral groove 16. A return spring 101 is installed on each push rod 14, and a moving clamping force can be applied under the action of the return spring 101. Therefore, when the fixing sleeve 6 is inserted into the insertion rod 9, it does not need to be rotated along the spiral groove 16, but can be slidably connected, and then the fixing sleeve 6 is pressed against the fixing plate 3, thereby ensuring the convenience of pre-fixing. When it needs to be released, it only needs to be pulled outward, thereby ensuring the fixing effect.

[0030] See also Figure 3 and Figure 4 As an implementation method of the clamping mechanism: the clamping mechanism includes a push rod 14, a plurality of telescopic holes 15 are provided on the side wall of the fixed sleeve 6, and the push rod 14 is slidably connected in each telescopic hole 15, a spiral groove 16 is provided on the side wall of the fixed rod 4, and the push rod 14 abuts in the spiral groove 16, and a return spring 101 is installed on each push rod 14, and the return spring 101 is connected to the side wall of the fixed sleeve 6, each push rod 14 is provided with a round head 17, and a plurality of round heads 17 abut on the inner wall of the limiting sleeve 8, and a telescopic sleeve 18 is coaxially provided on the lower end surface of the fixed sleeve 6, and the positioning rod 5 is slidably connected in the telescopic sleeve 18.

The rotation of the fixed sleeve 6 can be driven by rotating the hexagonal sleeve 13. Due to the threaded connection of multiple push rods 14 and the spiral groove 16, it is only necessary to fix it in the final stage, and there is no need to rotate along the spiral groove 16 throughout the whole process, thereby ensuring the convenience of fixation.

[0032] In summary, when the overall equipment is in use or running: when the valve body 2 needs to be pre-fixed, the positioning rod 5 on the fixing rod 4 passes through the fixing plate 3, and then the fixing sleeve 6 is slidably connected to the positioning rod 5, and each telescopic hole 15 is slidably connected to the push rod 14, and the push rod 14 is abutted in the spiral groove 16. A return spring 101 is installed on each push rod 14, and a moving clamping force can be applied under the action of the return spring 101. Therefore, when the fixing sleeve 6 is inserted into the insertion rod 9, it does not need to be rotated along the spiral groove 16, but can be slid and connected, and then the fixing sleeve 6 is pressed against the fixing plate 3, thereby ensuring the convenience of pre-fixing. When it needs to be released, it only needs to be pulled outward, thereby ensuring the fixing effect.

[0033] When the debugging is completed and the valve body 2 needs to be fixed, first slide the limit sleeve 8 upward so that the round head 17 is pressed against the limit sleeve 8, and the insertion rod 9 is connected to the insertion hole 10. The rotation of the fixed sleeve 6 can be driven by rotating the hexagonal sleeve 13.
