Description

Technical Field

[0001] The utility model relates to the technical field of electric valve equipment, in particular to a torque detection device for an electric valve actuator. Background Technique

[0002] Simply put, an electric valve is to control a valve with an electric actuator to realize the opening and closing of the valve. Torque is the main parameter for selecting a driving device for the valve, and its value is an important indicator for measuring the economy and quality of the valve. When the torque detection device of the valve electric actuator detects the torque of the electric actuator, the device is directly connected to the electric actuator. It belongs to a precision instrument and lacks the function of storing and protecting the torque detection device of the valve electric actuator when it is not in use. It is easy to be attached with dust when exposed for a long time. At the same time, it does not have good protective facilities, and it is easy to cause the torque sensor to break due to excessive torque and hurt others.

[0003] According to an electric valve actuator torque detection device disclosed in the patent publication number CN 221549890 U, the device has the function of storing and protecting the torque detection device of the valve electric actuator when it is not in use, preventing it from being easily attached with dust when exposed for a long time and shortening its service life. At the same time, if the torque sensor breaks due to excessive torque and hurts others, when the protective plate is impacted, it will squeeze the return spring, and at the same time, the damper will support and absorb the impact force. The fracture and splashing generally spread in the vertical direction. When the protective plate is hit, it will squeeze the rubber layer column, and the rubber layer column has a good effect on absorbing the impact force; however, the device is not convenient for disassembling the torque sensor, so it is not convenient for manual inspection and maintenance of the torque sensor, which affects the applicability of the device.

Specific embodiments

[0030] In order to have a clearer understanding of the technical features, objectives and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0031] Example 1: As Figures 1-5As shown in the figure, the utility model provides a technical solution: a torque detection device for an electric valve actuator, including a base 1, a protective box 2 fixedly installed on the upper part of the base 1, a PLC controller 4 fixedly installed on the right side of the protective box 2, a display screen 5 fixedly installed on the right side of the protective box 2, a torque sensor 6 arranged inside the protective box 2, and a connection component 3 arranged between the base 1 and the protective box 2. The connection component 3 includes a disassembly and assembly mechanism 31 arranged inside the protective box 2, and a moving mechanism 32 arranged at the lower part of the base 1. The disassembly and assembly mechanism 31 includes a first electric push rod 311 fixedly installed at the bottom of the inner wall of the protective box 2. The output end of the first electric push rod 311 is fixedly connected with a lifting plate 312. A convex groove 313 is formed in the upper part of the lifting plate 312. A convex column 314 is slidably connected to the inner wall of the convex groove 313. An installation plate 315 is fixedly installed on the upper part of the convex column 314. A clamping groove 316 is formed in the front part of the convex column 314. A sliding groove 317 is formed in the front part of the lifting plate 312. A sliding rod 318 is fixedly connected to the inner wall of the sliding groove 317. A slider 319 is slidably connected to the outer wall of the sliding rod 318. A first spring 3110 is fixedly connected to the inner wall of the sliding groove 317. A limiting rod 3111 is fixedly connected to the outside of the slider 319. One end of the limiting rod 3111 is movably connected with a clamping rod 3112. The outer end of the clamping rod 3112 is fixedly connected with a pull rod. A second spring 3113 is fixedly connected to the outside of the limiting rod 3111. A groove 3114 is formed in the top of the inner wall of the protective box 2. A damper 3115 is fixedly installed on the inner wall of the groove 3114. A third spring 3116 is fixedly connected to the inner wall of the groove 3114. The bottom end of the damper 3115 is fixedly connected with a top plate 3117.

[0032] In this embodiment, the upper part of the installation plate 315 is fixedly installed with the torque sensor 6. One end of the first spring 3110 is fixedly connected with the slider 319. The clamping rod 3112 is clamped with the clamping groove 316. Through the cooperation of the first electric push rod 311, the lifting plate 312, the convex groove 313, the convex column 314, the installation plate 315, the clamping groove 316, the sliding groove 317, the sliding rod 318, the slider 319, the first spring 3110, the limiting rod 3111, the clamping rod 3112, and the second spring 3113, it is convenient for manual disassembly of the installation plate 315, so as to facilitate manual maintenance and repair of the torque sensor 6 fixedly installed on the upper part of the installation plate 315, thereby increasing the applicability of the device.

[0033] Furthermore, the outer end of the second spring 3113 is fixedly connected with the pull rod, and the inner side of the limiting rod 3111 is in close contact with the outer side of the convex column 314.

[0034] Furthermore, the bottom end of the third spring 3116 is fixedly connected with the top plate 3117, and a buffer cotton is fixedly installed at the bottom of the top plate 3117. Through the cooperation of the groove 3114, the damper 3115, the third spring 3116, and the top plate 3117, it can prevent the torque sensor 6 from breaking due to excessive torque and hurting others by mistake.

[0035] Furthermore, there are two convex columns 314, which are symmetrically distributed at the bottom of the mounting plate 315.

[0036] When the device is in use, the door of the protective box 2 at the front is manually opened. Then, the lifting plate 312 is driven by the first electric push rod 311 to perform lifting adjustment, so that the height of the torque sensor 6 can be adjusted, and thus it can be applied to electric valves of different heights. Then, the detection operation can be carried out through the torque sensor 6. Furthermore, when it is necessary to disassemble the mounting plate 315, only need to manually hold the pull rod and pull the clamping rod 3112 outwards, so that the clamping rod 3112 can be separated from the clamping groove 316. Then, under the action of the elastic force of the first spring 3110, the slider 319 can move in the chute 317 through the slide rod 318, so that the limiting rod 3111 fixedly connected to the outside of the slider 319 can be far away from the outside of the convex column 314. Then, the mounting plate 315 can be taken out manually, which is convenient for manual maintenance and repair of the torque sensor 6 fixedly installed on the upper part of the mounting plate 315, thereby increasing the applicability of the device. And under the action of the damper 3115, the third spring 3116, and the top plate 3117, it can prevent the torque sensor 6 from breaking due to excessive torque and hurting others.

[0037] Embodiment 2: On the basis of Embodiment 1, a preferred embodiment of the torque detection device for an electric valve actuator provided by the present utility model is as Figures 1 to 5 shown: The moving mechanism 32 includes a second electric push rod 321 fixedly installed inside the base 1. The output end of the second electric push rod 321 is fixedly connected with a bottom plate 322. An installation column 323 is movably connected inside the bottom plate 322. A moving wheel 324 is arranged at the bottom of the installation column 323. The top end of the installation column 323 is fixedly connected with an installation disc 325. A fourth spring 326 is fixedly connected to the bottom of the installation disc 325. A limiting column 327 is fixedly connected to the upper part of the bottom plate 322. The top end of the limiting column 327 is fixedly connected with a limiting block. An inner groove 328 is opened inside the bottom plate 322. A pressing column 329 is sleeved inside the inner groove 328. A fifth spring 3210 is fixedly connected to the inner wall of the inner groove 328. A pressing groove 3211 is opened on the side wall of the installation column 323.

[0038] In this embodiment, the bottom end of the fourth spring 326 is fixedly connected to the bottom plate 322. The mounting plate 325 is slidably connected to the outer wall of the limiting column 327. Through the cooperation of the second electric push rod 321, the bottom plate 322, the mounting column 323, the moving wheel 324, the mounting plate 325, the fourth spring 326, the limiting column 327, the inner groove 328, the pressing column 329, the fifth spring 3210, and the pressing groove 3211, relative movement can occur between the base 1 and the ground. When the base 1 contacts the ground, the device can be more stable during use. When the moving wheel 324 contacts the ground, it is convenient for manual transportation of the device, thereby increasing the applicability of the device. At the same time, when the device is jolted during movement, a shock-absorbing effect can be achieved, thereby protecting the device and preventing damage to the device caused by jolts.

[0039] Further, one end of the fifth spring 3210 is fixedly connected to the pressing column 329, and the pressing column 329 is arranged in a pressing manner with the pressing groove 3211.

[0040] Furthermore, the pressing end of the pressing column 329 is hemispherical.

[0041] When the device needs to be moved, the second electric push rod 321 drives the bottom plate 322 to move downward, so that the mounting column 323 can drive the moving wheel 324 to move downward synchronously. When the moving wheel 324 moves downward and contacts the ground, due to the interaction of forces, the base 1 can be separated from the ground, and then the device can be transported manually. And when the device is jolted during movement, under the action of gravity, relative sliding can occur between the mounting column 323 and the bottom plate 322, so that the fourth spring 326 can be deformed, and thus a buffering effect can be achieved. And when relative sliding occurs between the mounting column 323 and the bottom plate 322, under the action of the elastic force of the fifth spring 3210, relative sliding can occur between the pressing column 329 and the pressing groove 3211. Therefore, under the combined action of the pressing force and the frictional force, the elastic potential energy generated by the fourth spring 326 during buffering can be reduced, and a shock-absorbing effect can be achieved, thereby protecting the device and preventing damage to the device caused by jolts.
