Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, and in particular to a high-pressure resistant ball valve with high pressure tolerance and extreme environment adaptability. Background Art

[0002] A ball valve is a valve driven by a valve stem and rotating around the axis of the ball valve. It can also be used for the regulation and control of fluids. Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, electric power, municipal engineering, and steel, playing a crucial role in the national economy.

[0003] When the existing ball valve is in use, water enters the ball valve through the water inlet pipe. If the flow rate of the water is too large, a strong water cone effect will be generated inside the ball valve, causing certain damage to the inner wall of the ball valve. In addition, the existing ball valve lacks an automatic pressure relief device. If the water pressure inside the ball valve is too high, the ball valve will be damaged. Moreover, when the ball valve is used in an extremely cold environment, water is likely to freeze inside the ball valve, causing the ball valve to become blocked. And when water freezes, its volume will increase, further pressing against the inner wall of the ball valve and causing the ball valve to be damaged. Therefore, manual handling is required in a timely manner, which is rather troublesome.

[0004] Based on this, we propose a high-pressure resistant ball valve with high pressure tolerance and extreme environment adaptability. Summary of the Invention

[0015] Preferably, the heat-conducting sleeve, spline sleeve, spline shaft, rotating shaft, blades, first friction wheel and second friction wheel are all made of materials with good heat-conducting performance.

[0016] The present invention has the following beneficial effects: 1. By providing a pressure relief mechanism, when the water pressure in the ball valve body increases, the water pressure will exert pressure on the pressure block, pushing the pressure block to move upward, thereby driving the sealing column to move upward to open the pressure relief hole. Part of the water flow will discharge through the pressure relief hole, thereby reducing the water pressure in the ball valve body to achieve the purpose of pressure relief and protecting the ball valve body from damage. 2. By providing a driving mechanism, water enters through the inlet pipe, flows through the ball valve body, and then discharges through the outlet pipe. When the water enters, the micro motor is started. The micro motor will drive the heat-conducting sleeve to rotate through the telescopic rod, and then drive the spline sleeve to rotate, drive the spline shaft to rotate, thereby driving the rotating shaft to rotate, driving a plurality of blades to rotate. Therefore, when the water flow passes through the blades, a swirl will be generated due to the rotation of the blades, thereby slowing down the flow rate of the water flow and reducing the water cone effect. 3. By providing a heating mechanism, when the ball valve body is applied in an extremely cold environment and the water flow in the ball valve body freezes, its volume will increase, thereby pushing the pressure block to move upward and maintaining a continuous pressure. The pressure block drives the T-shaped rod to move upward, and then the T-shaped rod will drive the connecting rod to move upward, driving the heat-conducting sleeve to move upward, and then driving the spline sleeve to move upward, causing the spline sleeve to disengage from the spline shaft. As a result, the rotating shaft will stop rotating, and the heat-conducting sleeve will drive the first friction wheel to move upward, causing the first friction wheel to fit with the second friction wheel. Intense friction will occur between the first friction wheel and the second friction wheel, thereby generating heat. The heat will be transferred to the spline sleeve through the heat-conducting sleeve, and then transferred to the rotating shaft and blades, melting the ice in the inlet pipe. Therefore, in an extremely cold environment, the ice in the ball valve body can be automatically removed, preventing the ball valve from being blocked for a long time and eliminating the need for manual treatment, making it more convenient to use. 4. By providing a vibration mechanism, due to the friction between the first friction wheel and the second friction wheel, the second friction wheel can be driven to rotate, driving the rotating rod to rotate, and then driving the first bevel gear to rotate, driving the second bevel gear to rotate, thereby driving the reciprocating lead screw to rotate, driving the slider to reciprocate. The slider will drive the sliding plug to reciprocate and seal through the push rod, and then drive the cross bar to reciprocate, driving the knocking head to reciprocate, continuously knocking on the side wall of the rotating shaft, causing the rotating shaft to vibrate, and the vibration will be synchronously transmitted to the blades and finally to the ice, causing the frozen ice to vibrate and accelerating the fragmentation of the ice, thereby increasing the melting speed of the ice. 5. By providing a jet mechanism, when the sliding plug reciprocally seals and slides, the air at the friction area between the first friction wheel and the second friction wheel will enter the rectangular cavity through the one-way intake pipe. Since the intense friction between the first friction wheel and the second friction wheel heats the surrounding air, the air entering the rectangular cavity has a certain amount of heat. Then, the hot air will enter the vertical groove through the one-way supply pipe, and then enter the intake cavity through the communication groove. Finally, the hot air will be ejected through multiple one-way air outlets to heat the surrounding ice, further increasing the melting speed of the ice. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] Refer to Figure 1 - Figure 7 , a high-pressure resistant ball valve with high-pressure resistance and extreme environment adaptation, including a ball valve body 1, and a water inlet pipe 2 and a water outlet pipe 3 are respectively fixedly connected to the side wall of the ball valve body 1; A pressure relief mechanism, the pressure relief mechanism includes a rotating shaft 4 rotatably connected to the inner wall of the water inlet pipe 2, a plurality of blades 5 are fixedly connected to the side wall of the rotating shaft 4, a pressure block 6 is hermetically slidably connected to the side wall of the water outlet pipe 3, the pressure block 6 penetrates through the inner wall of the water outlet pipe 3, a T-shaped rod 7 is fixedly connected to the upper end of the pressure block 6, two springs 8 are symmetrically fixedly connected to the lower end of the T-shaped rod 7, and the other ends of the two springs 8 are fixedly connected to the upper end of the water outlet pipe 3. Two pressure relief cylinders 9 are fixedly connected to the upper end of the water outlet pipe 3. The lower ends of the two pressure relief cylinders 9 communicate with the inside of the water outlet pipe 3. Two pressure relief holes 10 are symmetrically formed in the inner wall of the pressure relief cylinder 9, and a sealing column 11 is hermetically slidably connected to the inner wall of the pressure relief cylinder 9. A vertical rod 12 is fixedly connected to the upper end of the sealing column 11, and the upper end of the vertical rod 12 is fixedly connected to the lower end of the T-shaped rod 7.

[0021] Furthermore, if the water pressure inside the ball valve body 1 increases, the water pressure will exert pressure on the pressure block 6, overcome the elastic force of the spring 8, and push the pressure block 6 upward. Then, the T-shaped rod 7 will be driven to move upward, and thus the T-shaped rod 7 will drive the sealing column 11 to seal and slide upward through the vertical rod 12. When the sealing column 11 moves above the pressure relief hole 10, it will no longer block the pressure relief hole 10. Then, part of the water flow will be discharged through the pressure relief hole 10, thereby reducing the water pressure inside the ball valve body 1 and achieving the purpose of pressure relief, protecting the ball valve body 1 from damage. As the water pressure decreases, the pressure block 6 will reset under the action of the spring 8, and then drive the sealing column 11 to reset, and block the pressure relief hole 10 again.

[0022] A driving mechanism, the driving mechanism includes a heat-conducting sleeve 15; A heat supply mechanism, the heat supply mechanism includes a first friction wheel 18 fixedly connected to the side wall of the heat-conducting sleeve 15, a rotating rod 19 is rotatably connected to the upper end of the water inlet pipe 2, and a second friction wheel 20 is fixedly connected to the upper end of the rotating rod 19.

[0023] The driving mechanism includes a micro motor 13 fixedly connected to the upper end of the water inlet pipe 2 through a bracket. The upper end of the rotating shaft 4 penetrates through the upper end of the water inlet pipe 2 and is fixedly connected with a spline shaft 17. A plurality of telescopic rods 14 are fixedly connected to the side wall of the output end of the micro motor 13. The telescopic rods 14 can freely expand and contract. The lower end of the heat conducting sleeve 15 is fixedly connected with a spline sleeve 16. The lower ends of the plurality of telescopic rods 14 are all fixedly connected with the heat conducting sleeve 15. Both the heat conducting sleeve 15 and the spline sleeve 16 are slidably sleeved on the side wall of the spline shaft 17.

[0024] Further, water enters from the water inlet pipe 2, flows through the ball valve body 1, and then is discharged through the water outlet pipe 3. When the water enters, the micro motor 13 is started. The micro motor 13 drives the heat conducting sleeve 15 to rotate through the telescopic rods 14, and then drives the spline sleeve 16 to rotate, drives the spline shaft 17 to rotate, thereby driving the rotating shaft 4 to rotate, driving the plurality of blades 5 to rotate. Therefore, when the water flow passes through the blades 5, a swirl will be generated due to the rotation of the blades 5, and thus the flow rate of the water flow can be slowed down, and the water cone effect can be reduced.

[0025] The heat conducting sleeve 15, the spline sleeve 16, the spline shaft 17, the rotating shaft 4, the blades 5, the first friction wheel 18 and the second friction wheel 20 are all made of materials with good heat conducting performance.

[0026] The heating mechanism further includes an annular T groove 21 opened on the side wall of the heat conducting sleeve 15. The inner wall of the annular T groove 21 is slidably connected with a T-shaped block 22. A connecting rod 23 is fixedly connected to the side wall of the T-shaped block 22. The other end of the connecting rod 23 is fixedly connected to the upper end of the T-shaped rod 7.

[0027] Further, when the ball valve body 1 is applied in an extremely cold environment and the water flow in the ball valve body 1 freezes, its volume will increase, and then it will push the pressure block 6 to move upward and maintain a continuous pressure. The pressure block 6 drives the T-shaped rod 7 to move upward, and then the T-shaped rod 7 drives the connecting rod 23 to move upward, driving the heat conducting sleeve 15 to move upward, and then driving the spline sleeve 16 to move upward, so that the spline sleeve 16 is disengaged from the spline shaft 17 (as Figure 3 shown), and then the rotating shaft 4 will stop rotating, and the heat conducting sleeve 15 will drive the first friction wheel 18 to move upward, so that the first friction wheel 18 is in contact with the second friction wheel 20. Intense friction will be generated between the first friction wheel 18 and the second friction wheel 20, and then heat will be generated. The heat will be transferred to the spline sleeve 16 through the heat conducting sleeve 15, and then transferred to the rotating shaft 4 and the blades 5, which can melt the ice in the water inlet pipe 2. Therefore, in an extremely cold environment, the ice in the ball valve body 1 can be automatically removed, preventing the ball valve from being blocked for a long time, and there is no need for manual treatment, which is more convenient to use.

[0028] A vibration mechanism is installed on the water inlet pipe 2. The vibration mechanism includes a circular cavity 24 opened in the side wall of the water inlet pipe 2. A rectangular cavity 25 is opened in the side wall of the water inlet pipe 2. A sealing block 34 is fixedly connected to the inner wall of the rectangular cavity 25 in a sealed manner. A sliding plug 26 is slidably connected to the inner wall of the rectangular cavity 25 in a sealed manner. A cross bar 27 is fixedly connected to the side wall of the sliding plug 26. The other end of the cross bar 27 extends into the circular cavity 24 and is fixedly connected to a knocking head 28.

[0029] The vibration mechanism further includes a slider 29 slidably connected to the inner wall of the rectangular cavity 25. Two push rods 30 are symmetrically and fixedly connected to the side wall of the slider 29 close to the sliding plug 26. The other ends of the two push rods 30 are both fixedly connected to the sliding plug 26. A reciprocating lead screw 31 is rotatably connected to the side wall of the sealing block 34. The side wall of the reciprocating lead screw 31 is threadedly connected to the slider 29. The lower end of the rotating rod 19 extends into the rectangular cavity 25 and is fixedly connected to a first bevel gear 32. One end of the reciprocating lead screw 31 penetrates through the side wall of the sealing block 34 and is fixedly connected to a second bevel gear 33. The first bevel gear 32 is meshed with the second bevel gear 33.

[0030] Furthermore, due to the friction between the first friction wheel 18 and the second friction wheel 20, the second friction wheel 20 can be driven to rotate, driving the rotating rod 19 to rotate, and then driving the first bevel gear 32 to rotate, driving the second bevel gear 33 to rotate, thereby driving the reciprocating lead screw 31 to rotate, driving the slider 29 to reciprocate. The slider 29 will drive the sliding plug 26 to reciprocate and seal through the push rod 30, and then drive the cross bar 27 to reciprocate, driving the knocking head 28 to reciprocate, continuously knocking the side wall of the rotating shaft 4, causing the rotating shaft 4 to vibrate, and the vibration will be synchronously transmitted to the blade 5 and finally transmitted to the ice, causing the frozen ice to vibrate, accelerating the fragmentation of the ice, and thus increasing the melting speed of the ice.

[0031] An air jetting mechanism is installed in the blade 5. The air jetting mechanism includes an air inlet cavity 35 opened in the blade 5 (as Figure 7 shown). A plurality of one-way air outlet holes 36 are opened in the inner wall of the air inlet cavity 35. The one-way air outlet holes 36 only allow the air in the air inlet cavity 35 to be discharged. A vertical groove 37 is opened in the rotating shaft 4. The vertical groove 37 is communicated with the air inlet cavity 35 through a communication groove 38. The side wall of the ball valve body 1 is fixedly connected to a rotary joint 39 through a bracket. The lower end of the rotating shaft 4 penetrates through the lower end of the water inlet pipe 2 and is fixedly connected to the rotary joint 39.

[0032] The jet mechanism further includes a one-way air inlet pipe 40 fixedly connected to the inner wall of the rectangular cavity 25. The other end of the one-way air inlet pipe 40 is located below the second friction wheel 20. The air inlet of the one-way air inlet pipe 40 is specifically near the friction area between the first friction wheel 18 and the second friction wheel 20. And the one-way air inlet pipe 40 only allows air to enter the rectangular cavity 25. A one-way air supply pipe 41 is fixedly connected to the inner wall of the rectangular cavity 25. The other end of the one-way air supply pipe 41 is fixedly connected to the rotary joint 39. The one-way air supply pipe 41 only allows the air in the rectangular cavity 25 to be discharged.

[0033] Further, when the sliding plug 26 reciprocates and seals and slides, the air at the friction area between the first friction wheel 18 and the second friction wheel 20 will enter the rectangular cavity 25 through the one-way air inlet pipe 40. Since the intense friction between the first friction wheel 18 and the second friction wheel 20 will heat the air around them, the air entering the rectangular cavity 25 has a certain amount of heat. Then the hot air will enter the vertical groove 37 through the one-way air supply pipe 41, and then the hot air will enter the air inlet cavity 35 through the communication groove 38. Finally, the hot air will be ejected through a plurality of one-way air outlet holes 36 to heat the surrounding ice and further improve the melting speed of the ice.

[0034] A sphere 42 is sealingly and slidably connected to the inner wall of the ball valve body 1. A turning handle 43 is rotatably connected to the side wall of the ball valve body 1. The other end of the turning handle 43 penetrates through the inner wall of the ball valve body 1 and is fixedly connected to the sphere 42.

[0035] In the present invention, water enters through the water inlet pipe 2, flows through the ball valve body 1, and then is discharged through the water outlet pipe 3. When the water enters, the micro motor 13 is started. The micro motor 13 will drive the heat conduction sleeve 15 to rotate through the telescopic rod 14, and then drive the spline sleeve 16 to rotate, drive the spline shaft 17 to rotate, thereby drive the rotating shaft 4 to rotate, and drive a plurality of blades 5 to rotate. Therefore, when the water flow passes through the blades 5, a swirl will be generated due to the rotation of the blades 5, and thus the flow rate of the water flow can be slowed down and the water cone effect can be reduced.

[0036] If the water pressure in the ball valve body 1 increases, the water pressure will apply pressure to the pressure block 6, overcome the elastic force of the spring 8 and push the pressure block 6 to move upward, and then drive the T-shaped rod 7 to move upward. Thus, the T-shaped rod 7 will drive the sealing column 11 to seal and slide upward through the vertical rod 12. When the sealing column 11 moves above the pressure relief hole 10, it will no longer block the pressure relief hole 10. Then part of the water flow will be discharged through the pressure relief hole 10, thereby reducing the water pressure in the ball valve body 1 and achieving the purpose of pressure relief, protecting the ball valve body 1 from damage. As the water pressure decreases, the pressure block 6 will reset under the action of the spring 8, and then drive the sealing column 11 to reset, and block the pressure relief hole 10 again.

[0037] When the ball valve body 1 is applied in an extremely cold environment and the water flow inside the ball valve body 1 freezes, its volume will increase, and then it will push the pressure block 6 upward and maintain a continuous pressure. The pressure block 6 drives the T-shaped rod 7 upward, and then the T-shaped rod 7 drives the connecting rod 23 upward, driving the heat conducting sleeve 15 upward, and then driving the spline sleeve 16 upward, causing the spline sleeve 16 to disengage from the spline shaft 17. Then the rotating shaft 4 will stop rotating, and the heat conducting sleeve 15 will drive the first friction wheel 18 upward, making the first friction wheel 18 fit with the second friction wheel 20. Intense friction will occur between the first friction wheel 18 and the second friction wheel 20, generating heat. The heat will be transferred to the spline sleeve 16 through the heat conducting sleeve 15, and then to the rotating shaft 4 and the blade 5, which can melt the ice in the water inlet pipe 2.

[0038] In addition, due to the friction between the first friction wheel 18 and the second friction wheel 20, the second friction wheel 20 can be made to rotate, driving the rotating rod 19 to rotate, and then driving the first bevel gear 32 to rotate, driving the second bevel gear 33 to rotate, thus driving the reciprocating lead screw 31 to rotate, driving the slider 29 to slide reciprocally. The slider 29 will drive the sliding plug 26 to slide reciprocally and seal through the push rod 30, and then drive the cross bar 27 to move reciprocally, driving the knocking head 28 to move reciprocally, continuously knocking on the side wall of the rotating shaft 4, causing the rotating shaft 4 to vibrate, and the vibration will be synchronously transmitted to the blade 5 and finally to the ice, making the frozen ice vibrate, accelerating the fragmentation of the ice, and thus increasing the melting speed of the ice.

[0039] When the sliding plug 26 slides reciprocally and seals, the air at the friction part of the first friction wheel 18 and the second friction wheel 20 will enter the rectangular cavity 25 through the one-way air inlet pipe 40. Since the intense friction between the first friction wheel 18 and the second friction wheel 20 heats the air around them, the air entering the rectangular cavity 25 has a certain amount of heat. Then the hot air will enter the vertical groove 37 through the one-way air supply pipe 41, and then the hot air will enter the air inlet cavity 35 through the communication groove 38, and finally the hot air will be ejected through multiple one-way air outlet holes 36 to heat the surrounding ice, further increasing the melting speed of the ice. Therefore, in an extremely cold environment, the ice inside the ball valve body 1 can be automatically removed, preventing the ball valve from being blocked for a long time and eliminating the need for manual handling, making it more convenient to use.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
