Description

Technical Field

[0001] The invention relates to the field of ball valves, and in particular to a forged steel top-mounted buried fixed ball valve. Background Art

[0002] A ball valve is usually a valve that uses 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 element 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. A traditional ball valve is usually a ball with a through hole installed on a valve seat, and opening and closing are achieved by the rotation of the ball.

[0003] When the existing buried ball valve is in operation, especially at the moment when the pipeline is just opened, the internal pressure difference is too large, which causes the connected pipeline to fall off, causing the material in the pipeline to flow out, seriously affecting the safety of the ball valve when in use. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a forged steel top-mounted buried fixed ball valve, comprising a valve chamber, the outer surface of the valve chamber is symmetrically provided with connecting pipes, the opposite sides of the connecting pipes are fixedly connected to the outer surface of the valve chamber, the inner wall of the valve chamber is fixedly connected with a control mechanism, the outer surface of the connecting pipe is fixedly connected with a fixing mechanism, the fixing mechanism comprises a clamping mechanism, when in use, the pipeline is connected to the connecting pipe through the fixing mechanism, and the size of the gap is adjusted by the control mechanism, so that the pipelines on both sides are connected through the valve chamber, and the outermost protective tube surrounds and protects the pipeline, and ensures the normal operation of the fixing mechanism when buried underground, and also includes:

[0005] The anti-slip mechanism comprises a rotating groove fixedly connected to the outer surface of the clamping mechanism, the inner wall of the rotating groove is fixedly connected with a limiting block, the inner wall of the rotating groove is rotatably connected with an anti-slip block, the outer surface of the anti-slip block is fixedly connected with a pulling plate, the top of the pulling plate is fixedly connected with a clamping ring, the outer surface of the clamping ring is symmetrically provided with connecting plates, the inner wall of the connecting plate is fixedly connected to the outer surface of the clamping ring, when the anti-slip mechanism is connected to the pipeline, it is first connected to the outer surface of the pipeline through the connecting plate, and then connected to the clamping mechanism through the rotating groove. When the pipeline is forced to slide due to excessive pressure inside the valve body and slips out of the connection with the connecting pipe, the connecting plate is driven by the sliding of the pipeline to move the clamping ring, and the deformation of the pulling plate is used to rotate the anti-slip block, which is rotated inward to clamp the pipeline, and the sliding of the pipeline causes the anti-slip block to rotate inward to clamp, so as to limit the sliding of the pipeline and prevent the pipeline from being disconnected, causing the outflow of materials in the pipeline.

[0006] The outer surface of the clamping mechanism is symmetrically provided with curved plates, the inner wall of the curved plate is fixedly connected to the outer surface of the clamping mechanism, the bottom end of the curved plate is fixedly connected to a connecting ring, and the opposite side of the curved plate is symmetrically provided with top blocks, the inner wall of the top block is fixedly connected to the opposite side of the curved plate. When the pipes on both sides are connected to the pipes on both sides, they are connected to the outer surface of the connecting pipe through the connecting ring, and are connected to the pipe by an anti-slip mechanism, and the pipe is clamped by the clamping mechanism, and the curved plate is connected to the clamping mechanism. During the deformation of the curved plate, the inner top block is pressed against the outer surface of the connecting pipe, so that the outer surface of the connecting pipe is slightly deformed, thereby increasing the clamping force with the pipe.

[0007] The cam is secured to the inner wall of the cam and is provided with a spring which is adapted to move the spring back into engagement with the inner wall of the cam.

[0008] The control mechanism includes an adjusting mechanism, the top of the adjusting mechanism is fixedly connected to a slide cylinder, the inner wall of the slide cylinder is slidably connected to a ball rod, and the inner wall of the slide cylinder is rotatably connected to a protective mechanism. When controlling the passage of materials in the pipeline, the adjusting mechanism is controlled by using the protective mechanism to control the ball rod to slide inside the slide cylinder, thereby controlling and adjusting the flow rate through the valve body.

[0009] The adjusting mechanism comprises a sealing bin, a sealing ring is symmetrically arranged on the outer surface of the sealing bin, a curved rod is symmetrically arranged on the top of the sealing ring, the bottom end of the curved rod is fixedly connected to the top of the sealing ring, the top of the curved rod is fixedly connected to a rotating rod, the outer surface of the rotating rod is fixedly connected to a sealing disk, the top of the rotating rod is fixedly connected to a pressure block, and the top of the pressure block is fixedly connected to a pressure plate. When the adjusting mechanism is running, the pressure plate is moved by the pressure of the ball rod, so that the curved rod and the pressure block are deformed, and the rotating rod is rotated, driving the sealing disk to open the gap with the sealing ring, so that the material flows in the connecting pipe through the sealing bin. When the protective mechanism is damaged, the ball rod moves upward to stop the pressure on the pressure plate.

[0010] The protective mechanism includes a slip ring, a connecting rod is symmetrically arranged on the outer surface of the slip ring, the opposite side of the connecting rod is fixedly connected to the outer surface of the slip ring, the top of the connecting rod is fixedly connected to a turntable, the inner wall of the turntable is fixedly connected to a screw ring, the inner wall of the screw ring is threadedly connected to a stud, the outer surface of the stud is symmetrically arranged with an arc rod, the opposite side of the arc rod rotates with the outer surface of the stud, and the opposite side of the arc rod is fixedly connected to a fixing ring. When the protective mechanism is in operation, the screw ring is driven to rotate by rotating the turntable. At this time, the turntable is supported by the connecting rod to limit the up and down movement of the turntable. When the turntable is rotated, the stud moves, driving the ball rod to apply pressure to the adjusting mechanism. When the protective mechanism is damaged, the turntable or the top of the stud is broken, and the ball valve cannot be controlled at this time. At this time, the arc rod drives the bottom stud to slide under the action of its own elastic force, so that the ball rod drives to move upward and stops applying pressure to the adjusting mechanism.

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

[0012] 1. The present invention sets a limiting block and an anti-slipping block, and the anti-slipping block is rotated inward and clamped by the sliding of the pipeline to limit the sliding of the pipeline, thereby preventing the pipeline from being disconnected and causing the outflow of materials in the pipeline. At the same time, the limiting block limits the rotation angle when the anti-slipping block rotates, thereby preventing the clamping force from being too large and causing the pipeline to rupture, and at the same time preventing the anti-slipping block from rotating over an angle and losing the clamping effect.

[0013] 2. The present invention sets a curved plate and a top block. During the deformation of the curved plate, the top block on the inside presses against the outer surface of the connecting pipe, causing the outer surface of the connecting pipe to deform slightly, thereby increasing the clamping force with the pipe and cooperating with the anti-slip mechanism to limit the sliding and falling of the pipe.

[0014] 3. The present invention provides an arc rod and uses the deformation of the arc plate to compress the sliding shaft, thereby ensuring the normal operation of the clamping work and improving the adaptability of the clamping mechanism to different pipelines and the practicability of the device.

[0015] 4. The present invention arranges a bent rod and a pressure block. When the protective mechanism is damaged, the ball rod moves upward to stop pressing the pressure plate. With the cooperation of the bent rod and the pressure block, the pressure on both sides of the rotating rod is guaranteed to be the same, so that the rotating rods on both sides are equivalent to a rod supporting the sealing plates on both sides to block the ball valve, ensuring that the pipeline is closed and does not circulate when the ball valve is damaged and cannot be controlled.

[0016] 5. The present invention arranges an arc rod. When the protective mechanism is damaged, the turntable or the top of the stud is broken, and the ball valve cannot be controlled at this time, the arc rod drives the bottom stud to slide under the action of its own elastic force, so that the ball rod drives to move upward, stops applying pressure to the regulating mechanism, closes the ball valve, limits the flow of pipeline materials, and performs sealing protection when the valve body is damaged.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Embodiment 1, as Figure 1-Figure 5As shown, a forged steel top-mounted buried fixed ball valve includes a valve bin 1, a connecting pipe 4 is symmetrically arranged on the outer surface of the valve bin 1, and the opposite sides of the connecting pipe 4 are fixedly connected to the outer surface of the valve bin 1. The inner wall of the valve bin 1 is fixedly connected to a control mechanism 3, and the outer surface of the connecting pipe 4 is fixedly connected to a fixing mechanism 2, and the fixing mechanism 2 includes a clamping mechanism 22. When in use, the pipeline is connected to the connecting pipe 4 through the fixing mechanism 2, and the size of the passing gap is adjusted by the control mechanism 3, so that the pipelines on both sides are connected through the valve bin 1. At the same time, the outermost protective cylinder 6 surrounds and protects the pipeline to ensure the normal operation of the fixing mechanism 2 when buried underground, and also includes:

[0028] The anti-slip mechanism 21 comprises a rotation groove 212 fixedly connected to the outer surface of the clamping mechanism 22, a limiting block 213 is fixedly connected to the inner wall of the rotation groove 212, an anti-slip block 216 is rotatably connected to the inner wall of the rotation groove 212, a pull plate 214 is fixedly connected to the outer surface of the anti-slip block 216, a clamp ring 211 is fixedly connected to the top of the pull plate 214, a connecting plate 215 is symmetrically arranged on the outer surface of the clamp ring 211, and the inner wall of the connecting plate 215 is fixedly connected to the outer surface of the clamp ring 211. When the anti-slip mechanism 21 is connected to the pipeline, it is first connected to the outer surface of the pipeline through the connecting plate 215, and then connected to the clamping mechanism through the rotation groove 212. 22 connection, when the pipeline is forced to slide due to excessive pressure inside the valve body and slips out of the connection with the connecting pipe 4, the sliding of the pipeline drives the connecting plate 215, so that the clamping ring 211 moves, and the deformation of the pull plate 214 is used to rotate the anti-slip block 216, which rotates inward to clamp the pipeline. The sliding of the pipeline causes the anti-slip block 216 to rotate inward to clamp, thereby limiting the sliding of the pipeline and preventing the pipeline from being disconnected, causing the outflow of materials in the pipeline. At the same time, the limiting block 213 limits the rotation angle when the anti-slip block 216 rotates, preventing the clamping force from being too large and causing the pipeline to rupture, and at the same time preventing the anti-slip block 216 from rotating too much and losing the clamping effect.

[0029] The outer surface of the clamping mechanism 22 is symmetrically provided with curved plates 24, the inner wall of the curved plates 24 is fixedly connected to the outer surface of the clamping mechanism 22, the bottom end of the curved plate 24 is fixedly connected to a connecting ring 23, and the opposite side of the curved plate 24 is symmetrically provided with a top block 25, the inner wall of the top block 25 is fixedly connected to the opposite side of the curved plate 24. When the pipes on both sides are connected to the pipes on both sides, they are connected to the outer surface of the connecting pipe 4 through the connecting ring 23, and at the same time, the anti-slip mechanism 21 is used to connect to the pipe, and the clamping mechanism 22 is used to clamp the pipe, and at the same time, the curved plate 24 is used to connect to the clamping mechanism 22. During the deformation of the curved plate 24, the inner top block 25 is pressed against the outer surface of the connecting pipe 4, so that the outer surface of the connecting pipe 4 is slightly deformed, thereby increasing the clamping force with the pipe, and cooperating with the anti-slip mechanism 21 to limit the sliding and falling of the pipe.

[0030] The clamping mechanism 22 includes a groove ring 227, the outer surface of the groove ring 227 is symmetrically provided with a clamping plate 221, the opposite side of the clamping plate 221 is rotatably connected with an arc plate 222, the inner wall of the groove ring 227 is symmetrically provided with a sliding shaft 224, the outer surface of the sliding shaft 224 is slidably connected to the inner wall of the groove ring 227, the outer surface of the sliding shaft 224 is fixedly connected with a spring 223, the top of the spring 223 is fixedly connected to the inner wall of the groove ring 227, the bottom end of the sliding shaft 224 is fixedly connected with a clamping plate 226, the inner wall of the clamping plate 226 is symmetrically provided with an anti-slip plate 225, the outer surface of the anti-slip plate 225 is rotatably connected to the inner wall of the clamping plate 226 Dynamic connection, the outer surface of the connecting pipe 4 is fixedly connected with a protective tube 6, and the bottom of the protective tube 6 is fixedly connected with a base 5. When the clamping mechanism 22 is working, the clamping inner diameter of the sliding shaft 224 is adjusted by the spring to adapt to outer surfaces with different inner diameters. At the same time, the sliding shaft is clamped by the rotating arc plate 222 to apply pressure. The deformation of the arc plate 222 is used to push the sliding shaft 224 to press the clamping plate 226 to apply pressure on the pipeline surface. The deformation of the arc plate 222 is used to press the sliding shaft 224. While ensuring the normal operation of the clamping work, the adaptability of the clamping mechanism 22 to different pipelines is improved, thereby improving the practicability of the device.

[0031] Example 2, based on Example 1, continue to refer to Figure 6-Figure 8 The control mechanism 3 includes an adjusting mechanism 33, a slide cylinder 34 is fixedly connected to the top of the adjusting mechanism 33, a ball rod 32 is slidably connected to the inner wall of the slide cylinder 34, and a protective mechanism 31 is rotatably connected to the inner wall of the slide cylinder 34. When controlling the passage of materials in the pipeline, the regulating mechanism 33 is controlled by controlling the ball rod 32 to slide inside the slide cylinder 34 using the protective mechanism 31, so as to control and adjust the flow rate through the valve body.

[0032] The adjusting mechanism 33 comprises a sealing bin 331, a sealing ring 333 is symmetrically arranged on the outer surface of the sealing bin 331, a curved rod 336 is symmetrically arranged on the top of the sealing ring 333, the bottom end of the curved rod 336 is fixedly connected to the top of the sealing ring 333, a rotating rod 337 is fixedly connected to the top of the curved rod 336, a sealing disk 334 is fixedly connected to the outer surface of the rotating rod 337, a pressing block 335 is fixedly connected to the top of the rotating rod 337, and a pressing plate 332 is fixedly connected to the top of the pressing block 335. When the adjusting mechanism 33 is in operation, the pressing plate 332 is moved by the pressure of the ball rod 32. The movement causes the bent rod 336 and the pressure block 335 to deform, and the rotating rod 337 to rotate, driving the sealing disk 334 to open the gap with the sealing ring 333, so that the material can flow in the connecting pipe 4 through the sealing bin 331. When the protective mechanism 31 is damaged, the ball rod 32 moves upward and stops pressing the pressure plate 332. With the cooperation of the bent rod 336 and the pressure block 335, the pressure on both sides of the rotating rod 337 is ensured to be the same, so that the rotating rods 337 on both sides are equivalent to a rod supporting the sealing disks 334 on both sides to block the ball valve, ensuring that the pipeline is closed and no circulation occurs when the ball valve is damaged and cannot be controlled.

[0033] The protection mechanism 31 includes a slip ring 314, the outer surface of the slip ring 314 is symmetrically provided with a connecting rod 313, the opposite side of the connecting rod 313 is fixedly connected to the outer surface of the slip ring 314, the top of the connecting rod 313 is fixedly connected to a turntable 312, the inner wall of the turntable 312 is fixedly connected to a screw ring 311, the inner wall of the screw ring 311 is threadedly connected to a stud 317, the outer surface of the stud 317 is symmetrically provided with an arc rod 316, the opposite side of the arc rod 316 rotates with the outer surface of the stud 317, and the opposite side of the arc rod 316 is fixedly connected to a fixing ring 315. When the protection mechanism 31 is in operation, the rotation of the screw ring 311 is performed by rotating the screw ring 311. The rotating disk 312 drives the screw ring 311 to rotate. At this time, the rotating disk 312 is supported by the connecting rod 313 to limit the up and down movement of the rotating disk 312. When it rotates, the stud 317 moves, driving the ball rod 32 to apply pressure to the adjusting mechanism 33. When the protective mechanism 31 is damaged, the rotating disk 312 or the top of the stud 317 breaks, and the ball valve cannot be controlled at this time. At this time, the arc rod 316 drives the bottom stud 317 to slide under the action of its own elastic force, so that the ball rod drives it to move upward, stops applying pressure to the adjusting mechanism 33, closes the ball valve, limits the flow of pipeline materials, and performs sealing protection when the valve body is damaged.

[0034] When in use, the pipeline is connected to the connecting pipe 4 through the fixing mechanism 2, and the size of the gap is adjusted through the control mechanism 3 so that the pipelines on both sides are connected through the valve chamber 1. At the same time, the outermost protective tube 6 surrounds and protects the pipeline to ensure the normal operation of the fixing mechanism 2 when buried underground.

[0035] When the pipes on both sides are connected to each other, they are connected to the outer surface of the connecting pipe 4 through the connecting ring 23, and are connected to the pipes by the anti-slip mechanism 21, and are clamped by the clamping mechanism 22, and are connected to the clamping mechanism 22 by the bent plate 24.

[0036] When the anti-slip mechanism 21 is connected to the pipeline, it is first connected to the outer surface of the pipeline through the connecting plate 215, and then connected to the clamping mechanism 22 through the rotating groove 212. When the pipeline is forced to slide due to excessive pressure inside the valve body and slips out of the connection with the connecting pipe 4, the sliding of the pipeline drives the connecting plate 215 to move the clamping ring 211, and the deformation of the pulling plate 214 is used to rotate the anti-slip block 216, which rotates inward to clamp the pipeline.

[0037] When the clamping mechanism 22 is working, the clamping inner diameter of the sliding shaft 224 is adjusted by the spring to adapt to outer surfaces with different inner diameters. At the same time, the sliding shaft is clamped by the rotating arc plate 222 to apply pressure. Through the deformation of the arc plate 222, the sliding shaft 224 is pushed to press the clamping plate 226 to apply pressure on the pipe surface.

[0038] When controlling the passage of the material in the pipeline, the protection mechanism 31 is used to control the ball rod 32 to slide inside the slide cylinder 34 to control the regulating mechanism 33, thereby controlling and regulating the flow rate through the valve body.

[0039] When the protective mechanism 31 is in operation, the screw ring 311 is driven to rotate by rotating the turntable 312. At this time, the turntable 312 is supported by the connecting rod 313 to limit the up and down movement of the turntable 312. When the turntable 312 is rotated, the stud 317 moves, driving the ball rod 32 to apply pressure to the adjustment mechanism 33.

[0040] When the adjusting mechanism 33 is in operation, the pressure plate 332 is moved by the pressure of the ball rod 32, so that the curved rod 336 and the pressure block 335 are deformed, and the rotating rod 337 is rotated, driving the sealing plate 334 to open the gap with the sealing ring 333, so that the material flows in the connecting pipe 4 through the sealing chamber 331.

[0041] 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.
