Abstract
Description
Technical Field
[0001] This utility model relates to the field of actuators, and more specifically, to an actuator for an electro-hydraulic linkage valve. Background Technology
[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their types and specifications are quite numerous.
[0003] A search revealed that Chinese patent CN217874405U discloses "An easy-to-install electro-hydraulic linkage valve," comprising a valve body; two pipes located on either side of the valve body, with the valve body and the two pipes fixedly connected by bolts; two arc-shaped support plates positioned on top of the two pipes; and a linkage mechanism consisting of two sets located on opposite sides of the valve body, connected to the two arc-shaped support plates to reverse the movement of the valve body. Each linkage mechanism includes a plug-in component and an adjusting component. The plug-in component is located on the side of the valve body, and the adjusting component is located on top of the arc-shaped support plate, connected to the plug-in component. The slider can be removed from the groove, facilitating disassembly of the linkage mechanism after installation, allowing for reuse and avoiding resource waste. However, the following drawbacks still exist:
[0004] (1) Existing valve actuators are connected to each other by the meshing of screw holes and bolts. During installation, the bolts need to be aligned with the screw holes on both sides at the same time. The position needs to be repeatedly calibrated during the alignment process. The base size for installation is limited, which brings inconvenience to the installation.
[0005] (2) The existing actuator is only fixed by bolts and the installation direction is singular, which makes the installation stability insufficient. Repeated operation during subsequent use will cause loosening and affect the stability of operation.
[0006] Therefore, we have made improvements to this and proposed a device for electro-hydraulic linkage valve actuators. Utility Model Content
[0007] The purpose of this utility model is to address the problems of inconvenient installation process and insufficient installation stability of existing valve actuators.
[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0009] An electro-hydraulic valve actuator is provided to improve the above-mentioned problems.
[0010] The present invention is as follows:
[0011] The valve includes a cartridge assembly at its upper end and clamping assemblies on both sides of the cartridge assembly.
[0012] The cartridge assembly includes a mounting slot on the upper side of the valve, an actuator is detachably inserted into the mounting slot, and inner slots are provided on the front and rear sides of the actuator. An inner plate is movably installed inside the inner slot. When the actuator needs to be installed, the front and rear pressure plates are pressed to move the inner plate into the inner slot, thereby driving the clamping plate to slide into the inner slot.
[0013] The clamping assembly includes side plates disposed on the outer surfaces of both sides of the actuator. A central groove is formed inside the center of each side plate. A first bevel gear is disposed on the transverse inner wall of the central groove. A knob is connected to the outer end of the first bevel gear. Second bevel gears that cooperate with the first bevel gear are disposed on the front and rear sides of the central groove. Twisting the knobs on both sides causes the first bevel gear connected to it to rotate, which in turn causes the second bevel gear to rotate, which in turn causes the screw connected to it to rotate. This engagement causes the telescopic plate to slide within the groove, facilitating synchronous control of the clamping assemblies on both sides.
[0014] As a preferred technical solution of this utility model, a retaining plate is provided on the outer side of the lower end of the inner plate, and a retaining groove is provided on the front and rear sides of the mounting groove to cooperate with the retaining plate. When the pressure on the pressure plate is released, the spring and the telescopic rod lose their thrust and push the inner plate outward, thereby driving the retaining plate to insert into the aligned retaining groove, thus completing the quick installation of the actuator.
[0015] As a preferred technical solution of this utility model, a telescopic rod is provided on the surface of the inner plate away from the card plate. A spring is fitted on the outer wall of the telescopic rod. When the telescopic rod and the spring are squeezed, they contract and release the pressure on the pressure plate. The spring and the telescopic rod lose their thrust and push the inner plate outward. The elasticity of the spring makes it easy to control the disengagement or insertion.
[0016] As a preferred technical solution of this utility model, a pressure plate is provided on the outer surface of the upper end of the inner plate. Pressing the pressure plates on both sides causes the inner plate to move into the inner groove, which facilitates the control of the insertion component by squeezing or releasing the pressure plates.
[0017] As a preferred technical solution of this utility model, the center groove is provided with slots on the front and rear exteriors, and a screw is provided inside the slot. A telescopic plate is fitted on the outer wall of the screw. When the screw rotates, it engages and drives the telescopic plate to slide in the slot. Under the limitation of the limiting plate embedded in the limiting groove, the front and rear clamping plates move stably in opposite directions to clamp them on the outside of the pipes on both sides of the valve, thereby stabilizing and reinforcing the installation of the actuator.
[0018] As a preferred technical solution of this utility model, the slotted sidewall is provided with a limiting groove, the telescopic plate sidewall is provided with a limiting plate that cooperates with the limiting groove, and the lower outer end of the telescopic plate is provided with a clamping plate. Under the limiting position of the limiting plate embedded in the limiting groove, the front and rear clamping plates move stably in opposite directions to clamp the outside of the pipes on both sides of the valve, making the clamping process more stable and avoiding tilting or displacement during the clamping process.
[0019] As a preferred technical solution of this utility model, the rotation input end of the screw and the rotation output end of the second bevel gear are connected to each other. When the first bevel gear rotates, it meshes and drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate. The clamping process is made more convenient through the tooth meshing method.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] In the solution of this utility model:
[0022] 1. With the set clamping plate and slot, when the actuator needs to be installed, press the front and rear pressure plates to move the inner plate into the inner slot, thereby driving the clamping plate to slide into the inner slot. At the same time, squeeze the telescopic rod and spring to retract them, inserting the actuator downward into the installation slot. Release the pressure on the pressure plate, and the spring and telescopic rod lose thrust and push the inner plate outward, driving the clamping plate to insert into the aligned slot, thus completing the quick installation of the actuator and improving the ease of installation.
[0023] 2. With the first bevel gear, the second bevel gear, and the screw installed, after the actuator is installed, it needs to be reinforced with the pipes on both sides of the valve. Turning the knobs on both sides will drive the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate. This meshes with the telescopic plate, which slides in the slot. With the limit plate embedded in the limit groove, the front and rear clamping plates move stably in opposite directions, clamping them to the outside of the pipes on both sides of the valve, thus ensuring the stability and reinforcement of the actuator installation.

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] like Figure 1-5 As shown, this embodiment proposes an actuator for an electro-hydraulic linkage valve 1, including a valve 1, a cartridge assembly at the upper end of the valve 1, and clamping assemblies on both sides of the cartridge assembly.
[0036] The cartridge assembly includes a mounting groove 201 on the upper side of the valve 1, an actuator 202 is detachably inserted into the mounting groove 201, and inner grooves 203 are provided on the front and rear sides of the actuator 202. An inner plate 204 is movably installed inside the inner groove 203.
[0037] The clamping assembly includes side plates 301 disposed on the outer surfaces of both sides of the actuator 202. A central groove 302 is provided inside the center of the side plate 301. A first bevel gear 303 is disposed on the transverse inner wall of the central groove 302. A knob 304 is connected to the outer end of the first bevel gear 303. Second bevel gears 305 that cooperate with the first bevel gear 303 are disposed on the front and rear sides of the central groove 302.
[0038] like Figure 2 As shown, a retaining plate 205 is provided on the outer side of the lower end of the inner plate 204. The mounting groove 201 has slots 206 on the front and rear sides that cooperate with the retaining plate 205. The retaining plate 205 is inserted into the aligned slots 206 to complete the quick installation of the actuator 202.
[0039] like Figure 2 As shown, a telescopic rod 207 is provided on the side surface of the inner plate 204 away from the card plate 205. A spring 208 is fitted on the outer wall of the telescopic rod 207. When the spring 208 and the telescopic rod 207 lose their thrust, they push the inner plate 204 outward, causing the card plate 205 to be inserted into the aligned slot 206, thus completing the quick installation of the actuator 202.
[0040] like Figure 3 As shown, a pressure plate 209 is provided on the upper outer surface of the inner plate 204. Pressing the pressure plates 209 on both sides causes the inner plate 204 to move into the inner groove 203, thereby driving the clamping plate 205 to slide into the inner groove 203.
[0041] like Figure 4 As shown, the center groove 302 has slots 306 on its front and rear exteriors. A screw 307 is installed inside the slot 306. A telescopic plate 308 is fitted on the outer wall of the screw 307. The telescopic plate 308 slides in the slot 306. Under the limitation of the limiting plate 310 embedded in the limiting groove 309, the front and rear clamping plates 311 move stably in opposite directions to clamp the outside of the pipes on both sides of the valve 1.
[0042] like Figure 1As shown, a limiting groove 309 is provided on the side wall of the slot 306, and a limiting plate 310 is provided on the side wall of the telescopic plate 308 to cooperate with the limiting groove 309. A clamping plate 311 is provided at the lower outer end of the telescopic plate 308. The telescopic plate 308 slides in the slot 306. Under the limiting of the limiting plate 310 embedded in the limiting groove 309, the front and rear clamping plates 311 move stably in opposite directions to clamp the outside of the pipes on both sides of the valve 1, which stabilizes and reinforces the installation of the actuator 202. The clamping process is more stable through the limiting effect, and the displacement is avoided.
[0043] like Figure 4 As shown, the rotation input end of the screw 307 is connected to the rotation output end of the second bevel gear 305. When the second bevel gear 305 rotates, it drives the screw 307 connected to it to rotate, making clamping more convenient.
[0044] Specifically, when using this actuator: To install the actuator 202, press the front and rear pressure plates 209 to move the inner plate 204 into the inner groove 203, thereby causing the locking plate 205 to slide into the inner groove 203. Simultaneously, the telescopic rod 207 and spring 208 are compressed, causing them to retract and insert the actuator 202 downwards into the mounting slot 201. Releasing the pressure on the pressure plates 209 causes the spring 208 and telescopic rod 207 to lose thrust and push the inner plate 204 outwards, causing the locking plate 205 to insert into the aligned locking slot 206. This completes the rapid installation of the actuator 202. The installation improves the ease of installation of actuator 202. After the actuator 202 is installed, it needs to be reinforced with the pipes on both sides of valve 1. Turning the knobs 304 on both sides drives the first bevel gear 303 connected to it to rotate, which in turn drives the second bevel gear 305 to rotate, which in turn drives the screw 307 connected to it to rotate, which in turn drives the telescopic plate 308 to slide in the slot 306. Under the limit of the limiting plate 310 embedded in the limiting groove 309, the front and rear clamping plates 311 move stably towards each other, clamping them to the outside of the pipes on both sides of valve 1, thus stabilizing and reinforcing the installation of actuator 202.
[0045] All technical features in this embodiment can be freely combined according to actual needs.
[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
