Description

Technical Field

[0001] This utility model relates to the field of regulating valve processing technology, specifically a positioning device for regulating valve processing. Background Technology

[0002] As the core actuator of fluid control systems, regulating valves are widely used in petrochemical, municipal water supply, energy and power, biomedicine and other fields. Through the precise matching of valve core and valve seat, they can achieve precise control of fluid flow, pressure and temperature.

[0003] The prior art discloses a positioning device for processing regulating valves, with publication number CN222521244U. The device includes a frame, a clamping mechanism, and a connecting mechanism. The clamping mechanism is connected to the frame via the connecting mechanism. The clamping mechanism includes a vertical plate, a hydraulic component, and a clamping plate. One end of the vertical plate passes through the frame, one end of the hydraulic component is connected to the vertical plate, and the other end of the hydraulic component is connected to the clamping plate. Two clamping mechanisms are provided. The connecting mechanism includes a sliding groove, a slider, a telescopic rod, a block, a bearing, a rotating block, and a slot. The sliding groove is formed on the frame. One end of the slider is slidably connected to the sliding groove, and the other end of the slider extends into the vertical plate. One end of the telescopic rod is connected to the frame, and the other end of the telescopic rod is connected to one end of the block.

[0004] When the aforementioned positioning device for processing control valves needs to clamp control valves of different shapes, the control connection mechanism can separate the clamping mechanism from the equipment, and then replace it with a clamping mechanism that matches the control valve. However, the contact components of the aforementioned positioning device for processing control valves are rigid plates that lack elasticity and cannot adhere to the surface of the control valve. The contact area with the control valve is low during clamping, resulting in poor stability of the device's positioning and locking, and poor performance during use. Improvements are needed.

The connecting U-shaped frame 301 is fixedly connected to the inside of the positioning and placement frame 5. An inner slider 302 is slidably connected to the inner wall of the connecting U-shaped frame 301. A hydraulic telescopic rod 303 is fixedly connected to the left side of the connecting U-shaped frame 301. The inner slider 302 is fixedly connected to the right side of the hydraulic telescopic rod 303. A mounting screw 304 is threaded onto the right side of the mounting rod 304. A connecting strip 305 is fixedly connected to the right side of the connecting strip 305. A memory metal plate 306 is fixedly connected to the right side of the connecting strip 305. An inner spring 307 is fixedly connected inside the memory metal plate 306. A connecting frame 308 is fixedly connected to the bottom of the inner slider 302. A U-shaped plate 310 is fixedly connected to the bottom right side of the connecting frame 308. The top of the U-shaped plate 310 is fixedly connected to... The device includes an elastic pad 311, an inner sponge block 312 fixedly connected inside the elastic pad 311, a positioning airbag 309 fixedly connected inside the U-shaped plate 310, a connecting rod 313 fixedly connected to the front of the connecting frame 308, an air pump 314 fixedly connected to the front of the connecting rod 313, a delivery air pipe 315 fixedly connected to the bottom right side of the air pump 314, a connecting rod body fixedly connected to the right side of the inner slider 302, and a threaded connection groove opened on the right side of the surface of the connecting rod body. The thickness of the positioning airbag 309 is adapted to the distance from the bottom of the elastic pad 311 to the bottom of the inner end of the U-shaped plate 310. The elastic pad 311 and the inner sponge block 312 can reserve space so that there will be no obstruction after the positioning airbag 309 is inflated, ensuring the normal use of the device. The end of the delivery air pipe 315 away from the air pump 314 is fixedly connected to the top of the positioning airbag 309 near the front.

[0026] The limiting connection assembly 4 includes a limiting rectangular plate 401, a connecting plate 402, a limiting ring 403, a locking stud 404, a connecting disc 405, and an elastic sleeve 406. The limiting rectangular plate 401 is fixedly connected to the top of the base 1 near the back side. The connecting plate 402 is fixedly connected to the bottom of the positioning frame 5 near the front side. The limiting ring 403 is fixedly connected to the front side of the connecting plate 402. The connecting disc 405 is fixedly connected to the front side of the locking stud 404. The elastic sleeve 406 is fixedly connected to... On the surface of the connecting disc 405, the inner ring of the limiting ring 403 has an internal thread groove. The locking stud 404 is threaded to the inner ring of the limiting ring 403. The internal thread groove allows the locking stud 404 to be screwed in and moved backward to cooperate with the limiting rectangular plate 401 for further locking. Multiple clamping components work together to ensure accurate and stable positioning and good performance. There are six elastic sleeves 406, which are distributed in a ring at equal intervals on the surface of the connecting disc 405.

[0027] In use, place the regulating valve that needs to be positioned on top of the base 1, with its back side against the front of the limiting rectangular plate 401. Then, the positioning and locking components 3 inside the positioning frame plate 5 can be used for positioning and locking. During use, the four internal hydraulic telescopic rods 303 can be driven to push the inner slider 302 to move synchronously closer to the regulating valve placed in the middle. Before driving, the corresponding memory metal plate 306 needs to be installed according to the shape of the regulating valve. For regulating valves with a circular housing, an annular memory metal plate 306 needs to be installed. During installation, align the mounting screw 304 on the left side of the connecting strip plate 305 with the corresponding shape memory metal plate 306 with the thread groove on the surface of the connecting rod, and then screw in the mounting screw 304 to complete the installation. The memory metal plate 306 continuously moves towards the surface of the regulating valve until it contacts it. After contact, it covers the surface of the regulating valve. The cooperation between the memory metal plate 306 and the inner spring 307... When irregular protrusions appear, the pressure at that point increases, compressing the inner spring 307. The memory metal plate 306 at the corresponding point also deforms and adheres to the surface of the regulating valve. This applies to all four sides, ensuring stable positioning and locking of the regulating valve. An extended positioning airbag 309 is provided below to support the lower half of the regulating valve. When in use, the air pump 314, in conjunction with the air delivery pipe 315, delivers gas into the positioning airbag 309. The airbag inflates and clamps the lower part of the regulating valve, increasing the contact area during clamping and enhancing the stability of the positioning and locking. A limit connection component 4 is provided at the bottom of the positioning frame plate 5 near the front. When in use, the locking stud 404 can be screwed into the limit ring 403 and then turned backward until the back of the locking stud 404 contacts the front of the regulating valve, further clamping and locking. Multiple clamping components work together to ensure accurate and stable positioning, resulting in good performance.
