A vibration-resistant ball valve support structure

Abstract

This utility model discloses an anti-vibration ball valve support structure, relating to the field of valve structure technology. The utility model includes a valve body with a support block slidably connected to the bottom outer wall. By incorporating a first damper and a first spring, the rotation of the first positioning rod pushes the second positioning rod to rotate and push the slider, simultaneously causing the slider to press against the first damper. The first damper alleviates the pressure generated during slider movement and automatically compresses the outer first spring. The elasticity of the first spring automatically pushes the slider back to its original position. This achieves the goal of relieving pressure on the valve core ball through the first damper and simultaneously pushing the valve core ball back to its original position using the elasticity of the first spring. This prevents the valve core ball from vibrating at high frequencies due to continuous water flow impact, which could lead to metal fatigue cracks or even breakage at the connection between the valve stem and the valve core ball.

Description

Technical Field

[0001] This utility model belongs to the field of valve structure technology, and in particular relates to an anti-vibration ball valve support structure. Background Technology

[0002] According to the published patent CN222702597U, an anti-vibration ball valve is provided at the upper end of the valve body. A valve stem is threadedly connected to the valve cover. A valve plate is provided at the lower end of the valve stem. A handwheel is provided at the upper end of the valve stem. A fixing component is provided on the upper side of the rear end of the valve cover. The fixing component includes a horizontal plate, a sliding column, a limiting plate, a stud, a socket, a nut, and a moving component. After the valve plate at the lower end of the valve stem is closed by the handwheel, the position of the socket on the handwheel corresponds to the position of the sliding column. The limiting plate pushes the sliding column to slide in the horizontal plate, and the sliding column enters the socket of the handwheel. Then, the nut is screwed onto the stud at the upper end of the sliding column, and the sliding column can limit and fix the handwheel. By setting the fixing component, the handwheel can be limited, avoiding the risk of the valve stem at the lower end of the handwheel rotating due to vibration, which would cause the valve plate at the lower end of the valve stem to rotate and affect the sealing effect of the ball valve. However, the following shortcomings still exist:

[0003] After the above equipment is completed, it simply inserts the slide into the hole inside the handwheel and locks the handwheel to reduce the subsequent effects caused by vibration. However, because the water flow will continuously impact the valve body, the valve as a whole will vibrate at high frequency, which will easily cause cracks or even breakage caused by metal fatigue at the connection between the valve stem and the valve core ball. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration-resistant ball valve support structure. Through the damping mechanism and the support mechanism, it solves the problem that the valve body is constantly impacted by the water flow, causing high-frequency vibration of the valve as a whole, which leads to metal fatigue cracks or even breakage at the connection between the valve stem and the valve core ball.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a vibration-resistant ball valve support structure, including a valve body, and a support block is slidably connected to the bottom outer wall of the valve body;

[0007] The inner wall of the valve body is provided with a shock-absorbing mechanism, which includes a valve core ball. The outer wall of the valve core ball is slidably connected to the inner wall of the valve body. A valve stem is fixedly connected to the outer wall of the valve core ball. A handle is fixedly connected to the top outer wall of the valve stem. A protective sleeve is rotatably connected to the outer wall of the valve stem. A plurality of first positioning blocks are fixedly connected to the outer wall of the protective sleeve. A first positioning rod is rotatably connected to the outer wall of the plurality of first positioning blocks. A second positioning block is rotatably connected to the outer wall of the first positioning rod away from the first positioning block. A protective shell is slidably connected to the outer wall of the second positioning block. A second positioning rod is rotatably connected to the outer wall of the first positioning rod. A slider is rotatably connected to the outer wall of the second positioning rod away from the first positioning rod. A support mechanism is provided on the outer wall of the support block.

[0008] Furthermore, a first damper is fixedly connected to the outer wall of the slider, a first spring is fixedly connected to the outer wall of the first damper, and the outer wall of the protective shell is fixedly connected to the outer wall of the valve body.

[0009] Furthermore, the inner wall of the support mechanism is provided with a fixed seat, the outer wall of the fixed seat is slidably connected to the inner wall of the support block, and the inner wall of the fixed seat is rotatably connected to a first support rod.

[0010] Furthermore, an arc-shaped support plate is rotatably connected to the outer wall of the end of the first support rod away from the fixed seat. The outer wall of the arc-shaped support plate is fixedly connected to the outer wall of the valve body, and a limit groove is formed on the inner wall of the first support rod.

[0011] Furthermore, a connecting column is slidably connected to the inner wall of the limiting groove, a connecting rod is rotatably connected to the outer wall of the connecting column, and a first connecting block is rotatably connected to the outer wall of the end of the connecting rod away from the connecting column.

[0012] Furthermore, the outer wall of the first connecting block is fixedly connected to the inner wall of the support block, the outer wall of the connecting column is rotatably connected to a fixing rod, and the outer wall of the fixing rod away from the connecting column is rotatably connected to a second support rod.

[0013] Furthermore, a side arc-shaped support plate is rotatably connected to the outer wall of the second support rod, and the outer wall of the side arc-shaped support plate is fixedly connected to the outer wall of the valve body. A second connecting block is rotatably connected to the outer wall of the end of the second support rod away from the side arc-shaped support plate, and the outer wall of the second connecting block is slidably connected to the inner wall of the support block.

[0014] Furthermore, a second damper is fixedly connected to the bottom outer wall of the second connecting block, the outer wall of the second damper is fixedly connected to the inner wall of the support block, a second spring is fixedly connected to the outer wall of the second damper, and the outer wall of the second spring is fixedly connected to the outer wall of the second connecting block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a first damper and a first spring. During the rotation of the first positioning rod, the second positioning rod is pushed to rotate, which in turn pushes the slider. Simultaneously, the slider presses against the first damper, relieving the pressure generated during the slider's movement. The first damper also automatically compresses the outer first spring, using the elasticity of the first spring to automatically push the slider back to its original position. This achieves the goal of relieving the pressure on the valve core ball through the first damper, while simultaneously using the elasticity of the first spring to push the valve core ball back to its original position. This prevents the valve core ball from vibrating at high frequencies due to continuous impact from the water flow, which could lead to metal fatigue cracks or even breakage at the connection between the valve stem and the valve core ball.

[0017] 2. This utility model incorporates a first support rod and an arc-shaped support plate. The arc-shaped support plate drives the first support rod to rotate around the outer side of the arc-shaped support plate, while simultaneously pushing the fixed seat to move against the inner wall of the support block. The rotation of the first support rod also drives the connecting column to move, causing the connecting rod to rotate around the outer side of the first connecting block. Furthermore, the rotation of the connecting rod pushes the connecting column to move along the limiting groove inside the first support rod. This achieves the goal of supporting the bottom of the arc-shaped support plate through the rotation of the first support rod, while simultaneously using the connecting rod to share the pressure on the support rod. This prevents the valve shell from being constantly impacted by water flow, causing the valve to shake violently due to vibration, which could lead to loosening of the connection between the valve and the pipeline.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 As shown, this utility model is a vibration-resistant ball valve support structure, including a valve body 1, and a support block 101 is slidably connected to the bottom outer wall of the valve body 1;

[0029] A shock-absorbing mechanism 2 is provided on the inner wall of the valve body 1. The shock-absorbing mechanism 2 includes a valve core ball 201. The outer wall of the valve core ball 201 is slidably connected to the inner wall of the valve body 1. A valve stem 202 is fixedly connected to the outer wall of the valve core ball 201. A handle 203 is fixedly connected to the top outer wall of the valve stem 202. By rotating the handle 203, the valve stem 202 is rotated, and the angle of the valve core ball 201 within the valve body 1 is changed. A protective sleeve 204 is rotatably connected to the outer wall of the valve stem 202 to protect the valve stem 202. Several first positioning blocks 206 are fixedly connected to the outer wall of the protective sleeve 204. A first positioning rod 207 is rotatably connected to the outer wall of the several first positioning blocks 206. A second positioning block 208 is rotatably connected to the outer wall of the first positioning rod 207 away from the first positioning block 206. A protective shell 205 is slidably connected to the outer wall of the second positioning block 208. The movement of the protective sleeve 204... While the first positioning block 206 is moved, the first positioning rod 207 is rotated around the outside of the first positioning block 206, and the second positioning block 208 is moved inside the protective shell 205. The outer wall of the first positioning rod 207 is rotatably connected to the second positioning rod 209. The outer wall of the second positioning rod 209 away from the first positioning rod 207 is rotatably connected to the slider 210. The first positioning rod 207 is supported by the rotation of the second positioning rod 209 around the slider 210. The outer wall of the support block 101 is provided with a support mechanism 3. The outer wall of the slider 210 is fixedly connected to the first damper 211. The outer wall of the first damper 211 is fixedly connected to the first spring 212. The first damper 211 and the first spring 212 are used to relieve the pressure generated when the slider 210 moves. The outer wall of the protective shell 205 is fixedly connected to the outer wall of the valve body 1.

[0030] The inner wall of the support mechanism 3 is provided with a fixed seat 301. The outer wall of the fixed seat 301 is slidably connected to the inner wall of the support block 101. The inner wall of the fixed seat 301 is rotatably connected to a first support rod 302. The outer wall of the first support rod 302 away from the fixed seat 301 is rotatably connected to an arc-shaped support plate 303. The first support rod 302 supports the movement of the arc-shaped support plate 303 as it rotates around the interior of the fixed seat 301. The outer wall of the arc-shaped support plate 303 is fixedly connected to the outer wall of the valve body 1. A limit switch is provided on the inner wall of the first support rod 302. The inner wall of the groove 304 is slidably connected to a connecting column 305, and the outer wall of the connecting column 305 is rotatably connected to a connecting rod 306. When the connecting rod 306 rotates around the outer side of the first connecting block 307, it pushes the connecting column 305 to move along the limiting groove 304 inside the first support rod 302, thereby supporting the first support rod 302 and sharing the pressure on the first support rod 302. The outer wall of the end of the connecting rod 306 away from the connecting column 305 is rotatably connected to the first connecting block 307.

[0031] The outer wall of the first connecting block 307 is fixedly connected to the inner wall of the support block 101. A fixing rod 308 is rotatably connected to the outer wall of the connecting column 305. A second support rod 309 is rotatably connected to the outer wall of the fixed rod 308 away from the connecting column 305. The movement of the connecting column 305 pushes the fixing rod 308 to rotate around the outer side of the connecting column 305, while supporting the second support rod 309. A side arc-shaped support plate 310 is rotatably connected to the outer wall of the second support rod 309.

The outer wall of the second support rod 309 away from the side arc-shaped support plate 310 is rotatably connected to the outer wall of the valve body 1. The wall is rotatably connected to a second connecting block 311. The outer wall of the second connecting block 311 is slidably connected to the inner wall of the support block 101. A second damper 312 is fixedly connected to the bottom outer wall of the second connecting block 311. The second damper 312 is used to relieve the pressure generated when the second connecting block 311 moves. The outer wall of the second damper 312 is fixedly connected to the inner wall of the support block 101. A second spring 313 is fixedly connected to the outer wall of the second damper 312. The second damper 312 is pre-set to automatically compress the outer second spring 313 when it is squeezed. The elasticity of the second spring 313 increases the ability of the second damper 312 to relieve pressure. The outer wall of the second spring 313 is fixedly connected to the outer wall of the second connecting block 311.

[0032] One specific application of this embodiment is:

[0033] When the equipment is used by the operator, the vibration of the valve body 1 due to liquid flow continuously pushes the bottom arc-shaped support plate 303 to move. The arc-shaped support plate 303 drives the first support rod 302 to rotate around the outer side of the arc-shaped support plate 303, simultaneously pushing the fixed seat 301 to move against the inner wall of the support block 101. The rotation of the first support rod 302 also drives the connecting column 305 to move, simultaneously driving the connecting rod 306 to rotate around the outer side of the first connecting block 307. The rotation of the connecting rod 306 also pushes the connecting column 305 to move along the limiting groove 304 inside the first support rod 302. The movement of 305 pushes the fixed rod 308 to rotate around the outer side of the connecting rod 305, while simultaneously pushing the second support rod 309 to move. Since the second support rod 309 is in contact with the side arc-shaped support plate 310, which is installed on the side of the valve body 1, when the second support rod 309 is pushed by the fixed rod 308, the second support rod 309 will rotate around the outer side of the side arc-shaped support plate 310, while simultaneously driving the second connecting block 311 to move along the inner wall of the support block 101. The movement of the second connecting block 311 also compresses the second damper 312 at the bottom, thereby relieving the movement of the second connecting block 311. The pressure generated during flow is automatically compressed by the shortening of the second damper 312, which in turn compresses the outer second spring 313. The elasticity of the second spring 313 pushes the second connecting block 311 back to its original position in time. When the liquid flows, it impacts the valve core ball 201 and causes it to shift. When the valve core ball 201 moves, it drives the valve stem 202 to tilt slightly, thereby causing the outer side of the valve stem 202 to move. The movement of the protective sleeve 204 drives multiple first positioning blocks 206 to move. At the same time, it pulls the first positioning rod 207 to rotate around the first positioning block 206, while pushing the second positioning block 208 to move against the inner wall of the protective shell 205. This increases the resistance when the protective sleeve 204 moves, thereby reducing the possibility of displacement of the valve stem 202 and valve core ball 201. At the same time, during the rotation of the first positioning rod 207, it pushes the second positioning rod 209 to rotate and pushes the slider 210 to move along the inner wall of the protective shell 205. The slider 210 squeezes the first damper 211, which relieves the pressure generated when the slider 210 moves. The shortening of the first damper 211 automatically compresses the outer first spring 212. The elasticity of the first spring 212 automatically pushes the slider 210 back to its original position, and the elasticity also pushes the valve stem 202 and valve core ball 201 back to their original positions.
