[0001] This invention relates to the field of valve equipment technology, and in particular to a control valve manual adjustment rod mounting structure and valve device. Background Technology

[0002] A solenoid valve is an electromagnetically controlled valve device primarily used to control the flow of fluids. However, manual control is sometimes required during operation. To achieve this, a manual control device, such as a manual lever assembly, is installed on the solenoid valve. This manual control device allows for valve opening and closing without relying on electrical controls.

[0003] In existing technologies, a return spring is also installed on the valve body. During use, the return spring needs to provide axial and rotational freedom for the manual adjustment lever assembly while restricting other directional freedom, and also provide return elasticity for the manual adjustment lever assembly. The return spring mainly consists of a spring body and limiting parts formed by extending and bending from both ends of the spring body. The limiting parts are connected to the manual adjustment lever assembly. The spring body needs to be installed in the valve body in a staggered manner with the manual adjustment lever assembly. Therefore, the valve body design process needs to simultaneously reserve installation positions for both the spring body and the manual adjustment lever assembly, which increases the design difficulty of the valve body and makes the design of small-sized valves very difficult. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a control valve manual adjustment rod mounting structure and valve device, which reduces the installation volume required by the elastic mechanism while ensuring the function of the manual adjustment rod.

[0014] In a preferred embodiment of the present invention, the intermediate plate is inclined inward from the lower plate to the upper plate; or the intermediate plate is folded inward and protrudes outward.

[0015] In a preferred embodiment of the present invention, the lower plate is placed at the bottom of the limiting groove, and the outer edge of the lower plate abuts against the side wall of the limiting groove to form a limiting structure.

[0016] In a preferred embodiment of the present invention, the control valve manual adjustment rod mounting structure further includes an armature tube assembly. The end plate is provided with a mounting through hole, and the armature tube assembly is inserted into the mounting through hole. When the end plate and the mounting end face are in a mating state, the end of the armature tube assembly is disposed in the electromagnetic end cover. The armature tube assembly can form a first energized state and a second energized state in the electromagnetic end cover. The manual adjustment rod can push the armature tube assembly to switch between the first energized state and the second energized state.

[0017] In a preferred embodiment of the present invention, the detachable structure includes at least one first connecting hole provided on the mounting end face and a fixing screw provided corresponding to the first connecting hole, the fixing screw being able to pass through the end plate and be threaded into the first connecting hole.

[0018] In a preferred embodiment of the present invention, a positioning structure is provided between the end plate and the electromagnetic end cover.

The first energized state can be a connected state, and the second energized state can be a closed state. After use, a flexible mechanism provides a reset force to the manual adjustment lever, allowing it to return to its original position on the electromagnetic end cap for future use.

[0025] This invention utilizes a flexible mechanism in conjunction with a manual adjustment lever. While ensuring the functionality of the manual adjustment lever, the flexible mechanism and the lever do not require misalignment during installation, significantly reducing the installation space required for the flexible mechanism and improving space utilization.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Implementation Method 1

[0044] Please refer to the following: Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a control valve manual adjustment rod mounting structure, which includes: an electromagnetic end cap 1 having a mounting end face 11 with a limiting groove 12; a manual adjustment rod assembly 2 disposed on the electromagnetic end cap 1, the manual adjustment rod assembly 2 including a manual adjustment rod 21 movably inserted into the electromagnetic end cap 1, the manual adjustment rod 21 passing through the limiting groove 12; an elastic mechanism 3 disposed in the limiting groove 12, the elastic mechanism 3 being connected to the manual adjustment rod 21 and capable of pushing the manual adjustment rod 21 to reset; and an end plate 4, the end plate 4 being connected to the mounting end face 11 via a detachable structure, the end plate 4 being capable of limiting the elastic mechanism 3 within the limiting groove 12.

[0045] Overall, in use, the manual adjustment rod mounting structure of this control valve involves installing the manual adjustment rod assembly 2 onto the electromagnetic end cover 1, ensuring that at least a portion of the manual adjustment rod 21 is positioned within the limiting groove 12. Then, the elastic mechanism 3 is snapped onto the manual adjustment rod 21, and the end plate 4 is abutted against the mounting end face 11 of the electromagnetic end cover 1, fixing the elastic mechanism 3 within the limiting groove 12. The elastic mechanism 3 abuts against the side wall of the limiting groove 12 to form a limiting position, thereby improving the stability of the elastic mechanism 3. This invention, through the cooperation of the elastic mechanism 3 and the manual adjustment rod 21, ensures the functionality of the manual adjustment rod 21 without requiring misalignment between them, significantly reducing the installation space required for the elastic mechanism 3 and improving space utilization.

[0046] Specifically, the manual adjustment lever assembly 2 also includes a mounting end cap 22 that snaps onto the electromagnetic end cap 1, and the manual adjustment lever 21 is confined within the electromagnetic end cap 1 by the mounting end cap 22. When the manual adjustment lever 21 is manually pressed, it can push the armature tube assembly 5 to control the on / off state of the gas path.

[0047] Furthermore, a rotation locking structure is provided between the manual adjustment rod 21 and the electromagnetic end cover 1. When the manual adjustment rod 21 is pressed, rotating the manual adjustment rod 21 allows the manual adjustment rod 21 to use the protrusion on its body to lock the electromagnetic end cover 1, thereby forming a locked state.

[0048] Furthermore, a sealing ring 23 is fitted onto the lower part of the manual adjustment rod 21, and the manual adjustment rod 21 can form a sealing structure with the electromagnetic end cover 1 through the sealing ring 23. When the manual adjustment rod 21 slides inside the electromagnetic end cover 1, the sealing ring 23 can prevent fluid from leaking from between the manual adjustment rod 21 and the electromagnetic end cover 1.

[0049] In an embodiment of the present invention, the elastic mechanism 3 includes an elastic retaining spring 30 disposed in the limiting groove 12, and the elastic retaining spring 30 is engaged with the manual adjustment rod 21.

[0050] By attaching the elastic retaining spring 30 to the manual adjustment lever 21, the spring 30 can deform along the axial direction of the lever 21 when it is pressed down, thus avoiding affecting its normal use. When the lever 21 is not under force, the deformed spring 30 provides a restoring force, pushing the lever 21 back onto the electromagnetic end cap 1 for future use. The elastic retaining spring 30 has a simple and reliable structure, can output a stable restoring force, has low manufacturing cost, and offers better performance.

[0051] In an embodiment of the present invention, the elastic retaining spring 30 is formed by folding an elastic plate. By using an elastic plate to form the elastic retaining spring 30, the structure of the elastic retaining spring 30 is more complete, thereby providing a more stable restoring force. Furthermore, the elastic retaining spring 30 does not require welding or other connection processes during manufacturing, thereby reducing the risk of breakage and failure. Designers can determine the manufacturing material of the elastic plate according to the application requirements, such as metal, rubber, or plastic, etc., without specific limitations.

[0052] In embodiments of the present invention, such as Figure 4 and Figure 5 In the embodiment shown, the elastic retaining ring 30 includes an upper plate 31 and a lower plate 32 disposed opposite to each other, and an intermediate plate 33 disposed between the upper plate 31 and the lower plate 32.

[0053] Specifically, the upper plate 31 can be snapped onto the manual adjustment lever 21, the lower plate 32 can be supported at the bottom of the limiting groove 12, and the middle plate 33 connects the upper plate 31 and the lower plate 32 to provide elastic deformation to generate a restoring force. Designers can determine the shape of the upper plate 31, the middle plate 33, and the lower plate 32 according to the usage requirements, such as a rectangular structure, without specific limitations here.

[0054] In an embodiment of the present invention, the upper plate 31 is provided with a first through groove 311, the lower plate 32 is provided with a second through groove 321, the first through groove 311 and the second through groove 321 are arranged opposite to each other along the axial direction of the manual adjustment rod 21, the middle plate 33 is provided with a guide through groove 331, the two ends of the guide through groove 331 extend and connect with the first through groove 311 and the second through groove 321, the manual adjustment rod 21 is provided with a locking part 211, and the locking part 211 is provided with a locking groove 212; when the elastic retaining spring 30 and the manual adjustment rod 21 are in the locking state, the manual adjustment rod 21 can enter the first through groove 311 and the second through groove 321 through the guide through groove 331, and lock with the upper plate 31 through the locking groove 212.

[0055] Specifically, along the radial direction of the manual adjustment lever 21, the guide slot 331 has a larger radial size than the first slot 311 and the second slot 321, thereby facilitating the manual adjustment lever 21 to enter the first slot 311 and the second slot 321 from the guide slot 331.

[0056] The manual adjustment rod assembly 2 is installed on the electromagnetic end cover 1. When installing the elastic retaining ring 30, the guide slot 331 on the intermediate plate 33 is aligned with the rod body of the manual adjustment rod 21. Then, the elastic retaining ring 30 is pushed, causing the manual adjustment rod 21 to enter the first through slot 311 and the second through slot 321 through the guide slot 331. The upper plate 31 is aligned with the retaining groove 212 on the engaging part 211. As the manual adjustment rod 21 enters the first through slot 311 and the second through slot 321, the upper plate 31 simultaneously engages in the retaining groove 212. Finally, the end plate 4 is connected to the electromagnetic end cover 1, thus achieving a quick installation process.

[0057] The upper plate 31 can be axially limited by the two side walls of the slot 212, allowing the upper plate 31 and the manual adjustment lever 21 to move synchronously. When the manual adjustment lever 21 presses down on the upper plate 31, the upper plate 31 can store elastic potential energy through the intermediate plate 33. When the manual adjustment lever 21 is not subjected to external force, the upper plate 31 uses its elastic potential energy to generate a restoring force, driving the manual adjustment lever 21 to return to its original position.

[0058] In embodiments of the present invention, such as Figure 4 and Figure 6 In the illustrated embodiment, the intermediate plate 33 is inclined inward from the lower plate 32 to the upper plate 31. By inclining the intermediate plate 33, the connection rigidity between the intermediate plate 33 and the upper plate 31 and the lower plate 32 is reduced, making it easier for the intermediate plate 33 to undergo elastic deformation and store elastic potential energy, resulting in better performance. Figure 6 In the embodiment shown, the dashed line represents a schematic diagram of the elastic retaining spring 30 in a compressed state.

[0059] Furthermore, by tilting the intermediate plate 33 inward, a front end is formed between the intermediate plate 33 and the lower plate 32. The guide groove 331 located at this front end can be easily aligned with the rod of the manual adjustment lever 21, thereby improving the installation efficiency of the elastic retaining spring 30.

[0060] In another embodiment, such as Figure 5 In the illustrated embodiment, the intermediate plate 33 is folded in the center and protrudes outward. By folding the intermediate plate 33 in the center, the installation height of the intermediate plate 33 can be further reduced, thereby improving space utilization.

[0061] In other embodiments, designers may determine the number of folds and bending angles of the elastic plate according to usage requirements, without specific limitations.

[0062] In an embodiment of the present invention, the lower plate 32 is placed at the bottom of the limiting groove 12, and the outer edge of the lower plate 32 abuts against the side wall of the limiting groove 12 to form a limiting structure.

[0063] By abutting the outer edge of the lower plate 32 against the side wall of the limiting groove 12, and by also abutting the end plate 4 against the mounting end face 11 when the end plate 4 is engaged with it, the lower plate 32 is radially limited by the cooperation of the limiting groove 12 and the end plate 4, preventing the lower plate 32 from moving within the limiting groove 12 and improving the stability of the elastic retaining spring 30. Designers can determine the shape of the limiting groove 12 according to usage requirements, such as a rectangular groove; no specific limitations are imposed here.

[0064] In an embodiment of the present invention, see [reference] Figure 2 and Figure 3 The embodiment shown includes an armature tube assembly 5 in the control valve manual adjustment rod mounting structure. The end plate 4 has a mounting through hole 42, and the armature tube assembly 5 is inserted into the mounting through hole 42. When the end plate 4 and the mounting end face 11 are in a mating state, the end of the armature tube assembly 5 is located in the electromagnetic end cover 1. The armature tube assembly 5 can form a first energized state and a second energized state in the electromagnetic end cover 1. The manual adjustment rod 21 can push the armature tube assembly 5 to switch between the first energized state and the second energized state.

[0065] Specifically, the armature assembly 5 includes a valve body 51 and an armature tube 52 that drives the valve body 51. The valve body 51 can be disposed within the electromagnetic end cap 1 to form a first closed state and a second closed state. The armature tube 52 can acquire a control signal to control the valve body 51 to switch between the first closed state and the second closed state.

[0066] Furthermore, the operator can move the valve body 51 by manually adjusting the lever 21, thereby switching the valve body 51 between a first closed state and a second closed state. The first closed state can be a connected state, and the second closed state can be a closed state.

[0067] In an embodiment of the present invention, the detachable structure includes at least one first connecting hole 111 provided on the mounting end face 11, and a fixing screw 6 provided corresponding to the first connecting hole 111. The fixing screw 6 can pass through the end plate 4 and be threaded into the first connecting hole 111.

[0068] Specifically, three first connecting holes 111 can be provided. Two of the first connecting holes 111 are located below the limiting groove 12 and are symmetrically arranged about the axis of the manual adjustment rod 21. The other first connecting hole 111 is located at the bottom of the mounting end face 11.

[0069] The elastic retaining ring 30 can be snapped onto the manual adjustment rod 21 through the limiting groove 12. The elastic retaining ring 30 and the manual adjustment rod 21 do not need to be misaligned. Thus, by setting the first connecting hole 111 below the limiting groove 12, the elastic retaining ring 30 will not interfere with the fixing screw 6, thereby reducing the required installation space.

[0070] In existing technologies, the return spring and the manual adjustment lever 21 need to be installed in a staggered manner. This means that when arranging the fixing screw 6, the position of the return spring must be considered separately, which increases the design difficulty. Furthermore, when the fixing screw 6 avoids the return spring, it inevitably increases the installation space.

[0071] In another embodiment, the designer may adjust the number and position of the first connection holes 111 according to the connection requirements, without making specific restrictions.

[0072] In an embodiment of the present invention, a positioning structure 7 is provided between the end plate 4 and the electromagnetic end cover 1. The positioning structure 7 includes at least one positioning block 71 disposed on the mounting end face 11 and at least one positioning groove 41 disposed on the end plate 4.

[0073] Specifically, the mounting surface 11 of the electromagnetic end cover 1 has a mounting groove for the end mounting of the power supply armature assembly 5. Multiple positioning blocks 71 are provided, spaced apart around the mounting groove. The end plate 4 has positioning grooves 41 that match the positioning blocks 71. By cooperating with the positioning blocks 71 and the positioning grooves 41, the end plate 4 can be positioned and mated on the mounting surface 11 of the electromagnetic end cover 1, thereby improving the installation accuracy of the end plate 4.

This valve device, by utilizing the control valve manual adjustment rod mounting structure, can reduce the valve body size, thereby achieving a smaller valve design.

[0076] Specifically, the control valve is a solenoid valve. Of course, designers can adjust the type of control valve according to usage requirements, and no specific restrictions are imposed here.

[0077] In embodiments of the present invention, the valve device includes a main valve and at least one control valve, wherein the control valve is configured as a pre-control valve on the main valve, and the control valve includes a control valve manual adjustment lever mounting structure.
