Description

Technical Field

[0001] The invention relates to the field of ball valves, and in particular to a ball valve structure based on cam control. Background Art

[0002] Ball valves usually use a ball with a circular channel as an opening and closing element. The ball is opened and closed as the valve body rotates. The opening and closing part of the ball valve is a ball with a through hole, which rotates around an axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Traditional ball valves usually have a ball with a through hole installed on the valve seat, and the ball is opened and closed by rotating. Ball valves have been widely used in petroleum, chemical industry, power generation, water heating, water conservancy, shipbuilding, papermaking, atomic energy, aviation, rockets and other fields because of their advantages such as small fluid resistance, simple structure, tight and reliable, easy operation, fast opening and closing, and wide application range.

[0003] In the existing ball valve device, when the pipes on both sides of the pipe are closed, when the pipe seal is not opened, when the liquid on one side remains in the ball valve, the hydraulic pressure will impact the control mechanism. At this time, the ball rod will be impacted, and a small gap will appear, causing the material to overflow, seriously affecting the closing effect of the ball valve. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention adopts a technical solution to solve the technical problems thereof: a ball valve structure based on cam control, comprising a valve body, a sealing plate symmetrically arranged on the outer surface of the valve body, the opposite sides of the sealing plate being fixedly connected to the outer surface of the valve body, a connecting pipe symmetrically arranged on the outer surface of the valve body, the opposite sides of the connecting pipe being fixedly connected to the outer surface of the valve body, a connecting mechanism being fixedly connected to the outer surface of the connecting pipe, the inner wall of the sealing plate being rotatably connected to a rotating shaft, the outer surface of the rotating shaft being fixedly connected to a control mechanism, the control mechanism comprising an adjusting mechanism, and further comprising:

[0005] The anti-overflow mechanism comprises an anti-overflow ring fixedly connected to the inner wall of the adjusting mechanism, the inner wall of the anti-overflow ring is symmetrically provided with a top block, the top of the top block is in contact with the inner wall of the anti-overflow ring, the inner wall of the top block is fixedly connected with a connecting rod, the top of the connecting rod is fixedly connected with a pressure plate, the inner wall of the pressure plate is symmetrically provided with a connecting column, the outer surface of the connecting column is slidably connected to the inner wall of the pressure plate, the bottom of the pressure plate is symmetrically provided with a spring, the top of the spring is fixedly connected to the bottom end of the pressure plate, when the closure of the pipeline is not opened, when liquid on one side remains in the ball valve, the hydraulic pressure will impact the control mechanism, at this time the ball rod will be impacted, a small gap will appear, causing the material to overflow, at this time the hydraulic pressure impacts the pressure plate of the anti-overflow mechanism, the pressure plate presses the spring to deform, the pressure plate slides on the surface of the connecting column, the connecting rod is used to push the top block to deform, the inner wall of the anti-overflow ring is tightened, the anti-overflow ring is close to the surface of the ball rod, to ensure that when the ball valve is not opened and the flow of materials on both sides of the pipeline is prohibited, the material entering one side cannot affect the ball valve.

[0006] Wheel rods are symmetrically arranged on opposite sides of the adjusting mechanism, the inner wall of the wheel rod is rotatably connected to the outer surface of the adjusting mechanism, the outer surface of the wheel rod is rotatably connected to a cam, the inner wall of the cam is fixedly connected to the outer surface of the rotating shaft, the adjusting mechanism includes a sealing bin, the outer surface of the sealing bin is symmetrically arranged with limiting blocks, the opposite side of the limiting blocks is fixedly connected to the outer surface of the sealing bin, the inner wall of the sealing bin is slidably connected to a orifice plate, the pipeline is connected to the connecting pipe through the connecting mechanism, and at the same time, a motor is connected to the top end of the rotating shaft to drive the rotating shaft to rotate, so as to control the control mechanism so that the material in the pipeline flows through the inside of the valve body.

[0007] The outer surface of the orifice plate is fixedly connected with a connecting block, the outer surface of the connecting block is rotatably connected to the inner wall of the wheel rod, the inner wall of the sealing bin is fixedly connected with a speed limiting ring, the inner wall of the orifice plate is fixedly connected with a ball rod, the inner wall of the sealing bin is fixedly connected with a sealing ring, the outer surface of the valve body is fixedly connected with a base, the outer surface of the connecting pipe is fixedly connected with a connecting ring, the inner wall of the connecting pipe is fixedly connected to the outer surface of the sealing bin, and when the adjusting mechanism is running, the wheel rod is connected with the connecting block, thereby driving the orifice plate to slide in the sealing bin, moving the ball rod connected to the orifice plate, and opening the gap of the sealing ring to allow the material to flow through the gap. When the material flows in through the gap, the impact force is first offset by the speed limiting ring.

[0008] The connecting mechanism includes a connecting tube, a connecting ring is fixedly connected to the outer surface of the connecting tube, and fixing rods are symmetrically arranged on the outer surface of the connecting ring. The inner wall of the fixing rod is fixedly connected to the outer surface of the connecting ring. When the material in the pipeline starts to flow, the pressure difference will push the pipeline to break away from the connection with the ball valve. At this time, the pipeline is connected to the connecting pipe through the connecting tube and the fixing ring.

[0009] The inner wall of the connecting ring is symmetrically provided with rotating blocks, the outer surface of the rotating blocks is rotatably connected to the inner wall of the connecting ring, the outer surface of the connecting ring is fixedly connected to a pull cylinder, the outer surface of the pull cylinder is fixedly connected to a fixing ring, and the top end of the fixing rod is fixedly connected to a clamping mechanism. When the pipeline slides, the pull cylinder is pulled to deform, so that the connecting ring drives the rotating block to rotate and clamp inward, so that the outer surface of the connecting pipe is pressed inward, thereby strengthening the connection tightness with the pipeline. By increasing the connection tightness, the sliding of the pipeline is limited.

[0010] The cam is secured to the outer surface of the cam and is secured to the interior of the cam, and the cam is secured to the interior of the cam by a force that is regulated by the pressure of the control wheel.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention sets an anti-overflow ring and a top block, uses a connecting rod to push the top block to deform, and presses the inner wall of the anti-overflow ring tightly, so that the anti-overflow ring is close to the surface of the ball rod, ensuring that when the ball valve is not opened and the flow of materials on both sides of the pipeline is prohibited, the material entering one side cannot affect the ball valve, preventing the material from entering the ball valve through the gap during hydraulic shock.

[0013] 2. The present invention sets a speed limiting ring. When the material flows in through the gap, the impact force is first offset by the speed limiting ring, and then the material flows through the orifice plate, preventing the material with too fast flow rate from impacting the cam, causing the cam to vibrate and affecting the control effect.

[0014] 3. The present invention sets a rotating block, and the connecting ring drives the rotating block to rotate and clamp inward, so that the outer surface of the connecting pipe is pressed inward, thereby strengthening the connection tightness with the pipeline. By increasing the connection tightness, the sliding of the pipeline is restricted, ensuring the safety of the ball valve when adjusting the flow of materials in the pipelines on both sides, and preventing the pipeline from falling off accidentally.

[0015] 4. The present invention arranges a top column and a pull cylinder. When the pull cylinder is deformed, the inner wall contracts, pressing the top column to press the arc block, causing the arc block to deform and press the sliding shaft. The pressure is transmitted to the clamping plate through the sliding shaft, so that the clamping plate increases the force of clamping the pipe and limits the sliding of the pipe. The tension generated by the sliding of the pipe is used to increase the clamping force of the pipe, prevent the clamping force from being reduced when the pipe is not sliding, and prevent long-term huge pressure clamping, which may cause the pipe to break and cause material spillage.

At this time, the ball rod 225 will be impacted, and a small gap will appear, causing the material to overflow. At this time, the hydraulic pressure impacts the pressure plate 211 of the anti-overflow mechanism 21, causing the pressure plate 211 to press the spring 214 to deform, causing the pressure plate 211 to slide on the surface of the connecting column 215, and the connecting rod 212 is used to push the top block 216 to deform, and tighten the inner wall of the anti-overflow ring 213, so that the anti-overflow ring 213 is close to the surface of the ball rod 225, ensuring that when the ball valve is not opened and the material flow on both sides of the pipeline is prohibited, the material entering one side cannot affect the ball valve, preventing the material from entering the ball valve through the gap during hydraulic impact.

[0028] A wheel rod 24 is symmetrically arranged on the opposite side of the adjusting mechanism 22, and the inner wall of the wheel rod 24 is rotatably connected to the outer surface of the adjusting mechanism 22. A cam 23 is rotatably connected to the outer surface of the wheel rod 24, and the inner wall of the cam 23 is fixedly connected to the outer surface of the rotating shaft 4. The adjusting mechanism 22 includes a sealing bin 221, and a limiting block 222 is symmetrically arranged on the outer surface of the sealing bin 221. The opposite side of the limiting block 222 is fixedly connected to the outer surface of the sealing bin 221, and a perforated plate 226 is slidably connected to the inner wall of the sealing bin 221. The pipeline is connected to the connecting pipe 7 through the connecting mechanism 3. At the same time, a motor is connected to the top of the rotating shaft 4 to drive the rotating shaft 4 to rotate, so as to control the control mechanism 2, so that the material in the pipeline flows through the inside of the valve body 1, thereby realizing the flow of the material in the pipelines on both sides.

[0029] The outer surface of the orifice plate 226 is fixedly connected to the connecting block 223, the outer surface of the connecting block 223 is rotatably connected to the inner wall of the wheel rod 24, the inner wall of the sealing chamber 221 is fixedly connected to the speed limiting ring 224, the inner wall of the orifice plate 226 is fixedly connected to the ball rod 225, the inner wall of the sealing chamber 221 is fixedly connected to the sealing ring 227, the outer surface of the valve body 1 is fixedly connected to the base 5, the outer surface of the connecting pipe 7 is fixedly connected to the connecting ring 8, the inner wall of the connecting pipe 7 is fixedly connected to the outer surface of the sealing chamber 221, and the regulating mechanism When the mechanism 22 is in operation, the wheel rod 24 is connected to the connecting block 223, thereby driving the orifice plate 226 to slide in the sealing bin 221, so that the ball rod 225 connected to the orifice plate 226 moves, so that the ball rod 225 opens the gap of the sealing ring 227, allowing the material to flow through the gap. When the material flows in through the gap, the impact force is first offset by the speed limiting ring 224, and then the material flows through the orifice plate 226, so as to prevent the material with too fast flow rate from impacting the cam 23, causing the cam 23 to vibrate and affecting the control effect.

[0030] Example 2, based on Example 1, continue to refer to Figure 6-Figure 8 The connecting mechanism 3 includes a connecting tube 33, the outer surface of which is fixedly connected to a connecting ring 31, and the outer surface of the connecting ring 31 is symmetrically provided with fixing rods 34, and the inner wall of the fixing rods 34 is fixedly connected to the outer surface of the connecting ring 31. When the material in the pipeline starts to flow, the pressure difference will push the pipeline to break away from the connection with the ball valve. At this time, the pipeline is connected to the connecting pipe 7 through the connecting tube 33 and the fixing ring 37.

[0031] The inner wall of the connecting ring 31 is symmetrically provided with a rotating block 32, the outer surface of the rotating block 32 is rotatably connected to the inner wall of the connecting ring 31, the outer surface of the connecting ring 31 is fixedly connected to a pull cylinder 35, the outer surface of the pull cylinder 35 is fixedly connected to a fixing ring 37, and the top of the fixing rod 34 is fixedly connected to a clamping mechanism 36. When the pipeline slides, the pull cylinder 35 is pulled to deform, so that the connecting ring 31 drives the rotating block 32 to rotate and clamp inward, so that the outer surface of the connecting pipe 7 is pressed inward, and the connection tightness with the pipeline is strengthened. By increasing the connection tightness, the sliding of the pipeline is limited, and the safety of the ball valve when adjusting the flow of materials in the pipelines on both sides is guaranteed to prevent the pipeline from falling off accidentally.

[0032] The clamping mechanism 36 includes a fixed ring 361, the outer surface of the fixed ring 361 is symmetrically provided with a groove plate 363, the inner wall of the groove plate 363 is fixedly connected to the outer surface of the fixed ring 361, the inner wall of the groove plate 363 is slidably connected to a sliding shaft 364, the outer surface of the groove plate 363 is fixedly connected to a magnetic ring 368, the outer surface of the sliding shaft 364 is fixedly connected to a magnetic block 367, the bottom end of the sliding shaft 364 is fixedly connected to a clamping plate 366, the top end of the sliding shaft 364 is provided with an arc block 362, the bottom end of the arc block 362 is fitted with the top end of the sliding shaft 364, the top end of the arc block 362 is provided with a top column 365, the bottom end of the top column 365 is fixed to the arc block 36 2, the inner wall of the arc block 362 is fixedly connected to the top of the groove plate 363, and the top of the top column 365 is fixedly connected to the inner wall of the pull tube 35. At the same time, when the pull tube 35 is deformed, the inner wall contracts, pressing the top column 365 to press the arc block 362, so that the arc block 362 is deformed, pressing the sliding shaft 364, and transmitting the pressure to the clamping plate 366 through the sliding shaft 364, so that the clamping plate 366 increases the force of clamping the pipeline, restricts the sliding of the pipeline, and uses the pulling force generated by the sliding of the pipeline to increase the clamping force of the pipeline, prevent the clamping force from being reduced when the pipeline is not sliding, and prevent long-term huge pressure clamping, which may cause the pipeline to break and cause material overflow.

[0033] When in use, the pipeline is connected to the connecting pipe 7 through the connecting mechanism 3, and a motor is connected to the top of the rotating shaft 4 to drive the rotating shaft 4 to rotate, and the control mechanism 2 is controlled to make the material in the pipeline flow through the valve body 1.

[0034] When the shaft 4 rotates to make the control mechanism 2 work, the shaft 4 rotates to drive the cam 23 to rotate. During the rotation of the cam 23, the wheel rod 24 drives the adjustment mechanism 22 to work, opening the seal to allow the material inside the pipeline to flow in the pipelines on both sides.

[0035] When the adjusting mechanism 22 is in operation, the wheel rod 24 is connected to the connecting block 223, thereby driving the orifice plate 226 to slide in the sealing bin 221, so that the ball rod 225 connected to the orifice plate 226 moves, so that the ball rod 225 opens the gap of the sealing ring 227, and the material flows through the gap.

[0036] When the pipeline is not opened and the liquid on one side remains in the ball valve, the hydraulic pressure will impact the control mechanism 2. At this time, the ball rod 225 will be impacted, and a small gap will appear, causing the material to overflow. At this time, the hydraulic pressure impacts the pressure plate 211 of the anti-overflow mechanism 21, causing the pressure plate 211 to press the spring 214 to deform, causing the pressure plate 211 to slide on the surface of the connecting column 215, and the connecting rod 212 is used to push the top block 216 to deform, pressing the inner wall of the anti-overflow ring 213 to make the anti-overflow ring 213 close to the surface of the ball rod 225.

[0037] When the material in the pipeline begins to flow, the pressure difference will push the pipeline to break away from the connection with the ball valve. At this time, the pipeline is connected to the connecting pipe 7 through the connecting tube 33 and the fixing ring 37. When the pipeline slides, the pulling tube 35 is pulled to deform, so that the connecting ring 31 drives the rotating block 32 to rotate and clamp inward, so that the outer surface of the connecting pipe 7 is pressed inward, thereby strengthening the connection tightness with the pipeline.

[0038] At the same time, when the pull tube 35 is deformed, the inner wall contracts, pressing the top column 365 to press the arc block 362, causing the arc block 362 to deform and press the sliding shaft 364, and transferring the pressure to the clamping plate 366 through the sliding shaft 364, so that the clamping plate 366 increases the force of clamping the pipe and limits the sliding of the pipe.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
