Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to an adjustable flow bidirectional throttling electromagnetic valve. Background Technology
[0002] In the field of fluid control, some equipment uses a combination of bidirectional shut-off valves and throttle valves to achieve fluid control. However, this combination has a complex structure, occupies a large space, and has high installation and maintenance costs. Some equipment is only equipped with a unidirectional throttle valve, which can only meet the fluid throttling requirements in one direction and cannot cope with the complex working conditions of bidirectional fluid control. In addition, a large number of throttle valves on the market have the problem of non-adjustable flow rate, and their valve core and valve sleeve structures are fixed, so the fluid channel area cannot be changed. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: an adjustable flow bidirectional throttling solenoid valve, comprising a solenoid valve body, the solenoid valve body comprising a valve body and a valve sleeve, an iron core, and a valve core located within the valve body, the valve body being provided with an adjustment mechanism connected to the iron core, the adjustment mechanism being used to drive the iron core to move up and down along the height of the iron core.
[0004] Furthermore, the adjusting mechanism includes a pull rod, which includes a first rod end and a second rod end. The first rod end is movably connected to the end of the valve body, and the second rod end is detachably connected to the iron core. Rotating the pull rod can drive the iron core to move up and down along the height of the iron core.
[0005] Furthermore, a gap groove is provided at the end of the valve core away from the pull rod.
[0006] Furthermore, the iron core is provided with a locking groove that is adapted to the second rod end.
[0007] Furthermore, a gap α is provided between the valve sleeve and the iron core.
[0008] Furthermore, a handwheel is connected to the end of the first rod.
[0009] Furthermore, the outer wall of the pull rod is fitted with a rod sleeve, and the valve body has a fitting groove that matches the rod sleeve.
[0010] Furthermore, a sealing element is provided inside the sleeve, and the sealing element is in contact with the pull rod.
[0011] The beneficial effects of this utility model are as follows: The adjustment mechanism, which uses a rotating lever to move the iron core up and down, is simple and direct to operate, avoiding errors that may occur in complex processes. Simultaneously, the iron core engaging groove ensures a stable connection between the lever and the iron core, enabling accurate transmission of adjustment actions. The gap groove on the valve core cooperates with the adjustment mechanism to further refine flow regulation, enhancing the flexibility and precision of adjustment. The gap α between the valve sleeve and the iron core defines the flow regulation range. The handwheel allows operators to control the lever rotation amplitude with minimal effort and precision. Combined with the engaging groove between the lever sleeve on the outer wall of the lever and the valve body, it ensures stable lever rotation and smooth iron core movement during adjustment. The seal inside the lever sleeve effectively prevents fluid leakage, maintains stable internal pressure of the solenoid valve, avoids flow control deviations caused by leakage, and achieves stable bidirectional throttling and flow regulation functions.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-7This utility model provides the following technical solution: an adjustable flow bidirectional throttling solenoid valve, including a solenoid valve body, the solenoid valve body including a valve body 1 and a valve sleeve 2, an iron core 3 and a valve core 4 located inside the valve body 1, the valve body 1 is provided with an adjustment mechanism connected to the iron core 3, the adjustment mechanism includes a pull rod 5, the pull rod 5 includes a first rod end 6 and a second rod end 7, the first rod end 6 is movably connected to the end of the valve body 1, the second rod end 7 is detachably connected to the iron core 3, rotating the pull rod 5 can drive the iron core 3 to move up and down along the height of the iron core 3.
[0022] With the above structure, the adjustment method is simple and direct. The operator can accurately adjust the position of the iron core 3 by rotating the pull rod 5, which avoids the errors that may be caused by complex operation procedures. The stable structural connection ensures that the iron core 3 can accurately respond to the action of the pull rod 5 during the adjustment process, ensuring that the relative position between the valve core 4 and the valve sleeve 2 can be reliably changed with each adjustment, thereby realizing stable and accurate bidirectional throttling and flow regulation functions. This adjustable flow bidirectional throttling solenoid valve is used for throttling valves, solenoid valves, and system no-load and load speed switching.
[0023] In this embodiment, a gap groove 8 is provided at the end of the valve core 4 away from the pull rod 5.
[0024] In the above structure, the shape of the gap groove 8 is not limited. The gap groove 8 can also be irregular in shape. The gap groove 8 can change the fluid flow area. In conjunction with the adjustment mechanism, the flow regulation can be further refined, so that the solenoid valve can work stably under different flow requirements, and enhance the flexibility and accuracy of bidirectional throttling and flow regulation.
[0025] In this embodiment, the iron core 3 has a locking groove that matches the second rod end 7.
[0026] In the above structure, the locking groove ensures the stability of the connection between the pull rod 5 and the iron core 3, prevents the two from sliding relative to each other during adjustment, ensures accurate transmission of adjustment action, and thus stably realizes the bidirectional throttling and flow regulation functions, improving the working reliability of the solenoid valve.
[0027] In this embodiment, a gap α is provided between the valve sleeve 2 and the iron core 3.
[0028] The above structure defines the flow regulation range of the solenoid valve. When the regulating mechanism moves the iron core 3 up and down, the size of the gap α changes within its limited range, directly changing the channel area through which the fluid passes.
[0029] In this embodiment, a handwheel 9 is connected to the end of the first rod end 6.
[0030] With the above structure, the operator can apply force to rotate the lever 5 using the handwheel 9, which is more labor-saving and allows for precise control. When adjusting the flow rate using the gap α, the handwheel 9 can precisely control the rotation amplitude of the lever 5, thereby accurately adjusting the position of the iron core 3 within the adjustment range of the gap α, improving the adjustment accuracy.
[0031] In this embodiment, the outer wall of the pull rod 5 is fitted with a rod sleeve 10, and the valve body 1 has a fitting groove that is adapted to the rod sleeve 10.
[0032] With the above structure, during the flow regulation process by changing the gap α, this coordination ensures the stable rotation of the pull rod 5, promotes the smooth up-and-down movement of the iron core 3, and ensures that the iron core 3 can move as expected within the adjustment range of the gap α.
[0033] In this embodiment, a sealing element 11 is provided inside the sleeve 10, and the sealing element 11 is in contact with the pull rod 5.
[0034] The above structure effectively prevents fluid leakage, maintains stable internal pressure of the solenoid valve, and ensures that the system pressure will not change due to leakage when using the gap α for flow regulation, thus avoiding flow control deviation caused by leakage.
[0035] 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.
