Description

Technical Field

[0001] This utility model relates to the field of three-way ball valve technology, and in particular to a wear-resistant three-way ball valve. Background Technology

[0002] A three-way ball valve is a valve device used to control and regulate the flow direction of fluids in pipeline systems. It has three fluid channels and achieves the diversion, merging, or switching of fluid flow direction by rotating the internal ball. Three-way ball valves are widely used in petrochemical (mixed chemicals), energy and power (steam control), food and pharmaceutical (sanitary media handling), air conditioning systems (cooling and heating switching), building water supply and drainage (hot and cold water mixing), agricultural irrigation (multi-source water distribution), cryogenic liquids, highly corrosive media, or pipeline systems that need to be buried.

[0003] However, existing three-way ball valves have certain shortcomings:

[0004] First, the existing three-way ball valve has an internal alignment metal structure. During the process of conveying the medium, the continuous flow of the medium will cause internal wear of the ball valve, affecting the sealing performance and service life of the ball valve.

[0005] Secondly, existing three-way ball valves are divided into T-type three-way ball valves and L-type three-way ball valves. The T-type three-way ball valve can realize flow diversion, flow merging or full three-way flow, while the L-type three-way ball valve only connects two orthogonal pipes for flow direction switching. It cannot connect three pipes at the same time and cannot realize arbitrary switching between dual-channel or three-channel flow. Utility Model Content

[0006] The purpose of this application is to provide a wear-resistant three-way ball valve to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a wear-resistant three-way ball valve, comprising a valve body, a delivery pipe disposed at the middle position of the bottom outer wall of the valve body, and flow dividers disposed at both ends of the valve body. The valve body contains a valve cavity, which is circular in structure and is adapted to the delivery pipe and the flow dividers respectively. A control component is disposed within the valve cavity, and is adapted to the delivery pipe and the flow dividers respectively. The control component includes a ball core rotatably mounted inside the valve cavity. Flow dividers are formed on three outer walls of the ball core, and these flow dividers are interconnected and adapted to the delivery pipe and the flow dividers respectively. The diameter of each flow divider is the same as the diameter of the delivery pipe and the flow dividers. A protective pad, made of vapor-phase silica gel, is disposed on the inner wall of each flow divider. A sealing cap is disposed inside the ball core, and the sealing cap is adapted to the corresponding flow divider of the delivery pipe.

[0008] Preferably, a control sleeve is provided on the top of the ball core, with its two ends located on the top of the valve body and inside the ball core, respectively. A threaded rod is rotatably installed inside the control sleeve via a thread, the end of which is rotatably connected to a sealing cap. The control sleeve is rotatably connected to the inner wall of the top of the valve body and is fixedly connected to the top of the ball core.

[0009] Preferably, the outer wall of the sealing cover is covered with a sealing gasket, the sealing gasket is adapted to the sealing cover, the sealing gasket is made of silicone, the top of the threaded rod is provided with a control panel adapted to it, and the threaded rod is treated with rust and corrosion prevention.

[0010] Preferably, a control handle is provided on the top of one side of the outer wall of the control sleeve, and the outer wall of the control handle is covered with a matching anti-slip sleeve, which is made of anti-slip rubber.

[0011] Preferably, the outer wall of the threaded rod has equidistantly distributed positioning holes, the top of the outer wall of the control sleeve is inserted with a positioning pin, the positioning pin is adapted to the positioning hole, and the outer wall of the positioning pin is covered with a friction sleeve adapted to it.

[0012] Preferably, both the conveying pipe and the diversion pipe are provided with flanges at their ends. The flanges are adapted to the conveying pipe and the diversion pipe respectively. The outer wall of the flange is provided with a sealing ring adapted to it, and the thickness of the sealing ring is less than the thickness of the flange.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, during operation, the delivery pipe and the diversion pipe are connected to the pipeline respectively. When transporting the medium, since the ball core has diversion holes on three sides and the bottom, the medium enters the ball core through the diversion hole at the bottom of the ball core. At this time, if the diversion holes on both sides of the ball core correspond to the diversion pipes on both sides, the medium can flow towards the diversion pipes on both sides. If the medium needs to flow only along one side of the diversion pipe, it is only necessary to rotate the ball core so that the diversion holes on both sides are located inside the valve cavity, and align the diversion hole on one side with the diversion pipe that needs to be transported. At this time, since the other two opposite diversion holes are blocked inside the valve body, the medium can only flow through the bottom of the ball core and the diversion hole on one side, realizing unidirectional transport of the medium. During the transport of the medium, the protective pad of the vapor-phase silicone material protects the inside of the diversion hole. Due to the high tear resistance and corrosion resistance of the vapor-phase silicone, it can reduce the wear and corrosion of the ball core by the medium, making the ball core more durable and helping to improve the service life of the three-way ball valve.

[0015] 2. In this utility model, when the medium needs to flow between the two diversion pipes, it is only necessary to lower the sealing cover and merge it with the diversion hole at the bottom of the ball core, so that the sealing cover seals the diversion hole at the bottom, which can realize the flow of the medium between the two diversion pipes without backflow.

[0016] 2. In this utility model, when the sealing cover is in motion, rotating the threaded rod will drive the sealing cover to rise or fall, making it more convenient to use. When the sealing cover is combined with the diversion hole, the sealing gasket fills the surrounding gaps, improving airtightness and preventing media leakage. After the sealing cover is adjusted, inserting the positioning pin into the corresponding positioning hole will fix the threaded rod and prevent the threaded rod from rotating when the control sleeve is rotated.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figure 1-4The wear-resistant three-way ball valve shown includes a valve body 1, a delivery pipe 2 located at the middle of the bottom outer wall of the valve body 1, and flow dividers 3 at both ends of the valve body 1. The valve body 1 contains a circular valve cavity, which is adapted to the delivery pipe 2 and the flow dividers 3. A control component is also installed inside the valve cavity, adapted to the delivery pipe 2 and the flow dividers 3. The control component includes a ball core 4 rotatably mounted inside the valve cavity. Flow dividers 5 are formed on three sides of the outer wall of the ball core 4, and these flow dividers 5 are interconnected and adapted to the delivery pipe 2 and the flow dividers 3. The diameter of the diversion hole 5 is the same as that of the delivery pipe 2 and the diversion pipe 3. The inner wall of the diversion hole 5 is provided with a protective pad 9 that matches it. The protective pad 9 is made of gas phase silica gel. The ball core 4 is provided with a sealing cover 8. The sealing cover 8 matches the diversion hole 5 corresponding to the delivery pipe 2. The top of the ball core 4 is provided with a control sleeve 6. The two ends of the control sleeve 6 are located at the top of the valve body 1 and inside the ball core 4, respectively. A threaded rod 7 is installed inside the control sleeve 6 by a threaded rotation. The end of the threaded rod 7 is rotatably connected to the sealing cover 8. The control sleeve 6 is rotatably connected to the inner wall of the top of the valve body 1. The control sleeve 6 is fixedly connected to the top of the ball core 4.

[0025] With the above structure: During operation, the delivery pipe 2 and the diversion pipe 3 are connected to the pipeline respectively for medium transportation. Since the ball core 4 has diversion holes 5 on three sides and at the bottom, the medium enters the ball core 4 through the diversion hole 5 at the bottom of the ball core 4. At this time, if the diversion holes 5 on both sides of the ball core 4 correspond to the diversion pipes 3 on both sides, the medium can flow towards the diversion pipes 3 on both sides. If the medium needs to flow only along one side of the diversion pipe 3, it is only necessary to rotate the ball core 4 so that the diversion holes 5 on both sides are located inside the valve cavity, and align the diversion hole 5 on one side with the diversion pipe 3 that needs to be transported. At this time, since the other two opposite diversion holes 5 are blocked inside the valve body 1, the medium can only flow through the bottom of the ball core 4 and the diversion hole 5 on one side. To achieve unidirectional media transport, the protective pad 9 made of fumed silica gel protects the inside of the diversion hole 5 during the media transport process. Due to the high tear resistance and corrosion resistance of fumed silica gel, it can reduce the wear and corrosion of the ball core 4 by the media, making the ball core 4 more durable and helping to improve the service life of the three-way ball valve. When the media needs to flow between the two diversion pipes 3, it is only necessary to lower the sealing cover 8 and merge it with the diversion hole 5 at the bottom of the ball core 4, so that the sealing cover 8 seals the bottom diversion hole 5. Compared with the traditional three-way ball valve, by setting the protective pad 9 to protect the inside of the ball core 4, it is not easy to wear. At the same time, the sealing cover 8 is connected to the bottom of the ball core 4, which enables the media to flow between the two diversion pipes 3 without backflow.

[0026] like Figure 4As shown, the outer wall of the sealing cover 8 is covered with a sealing gasket 10, which is compatible with the sealing cover 8. The sealing gasket 10 is made of silicone. The top of the threaded rod 7 is equipped with a control panel 13 that is compatible with it. The threaded rod 7 is treated with anti-rust and anti-corrosion. When the sealing cover 8 is moving, rotating the threaded rod 7 can drive the sealing cover 8 to rise or fall, making it more convenient to use. The sealing gasket 10 covers the area around the sealing cover 8. When the sealing cover 8 is combined with the diversion hole 5, the sealing gasket 10 fills the surrounding gaps, improves airtightness, and prevents media leakage.

[0027] like Figure 2 As shown, a control handle 11 is provided on the top of the outer wall of one side of the control sleeve 6. The outer wall of the control handle 11 is covered with a matching anti-slip sleeve 12. The anti-slip sleeve 12 is made of anti-slip rubber. The control handle 11 controls the direction of the diversion hole 5 of the ball core 4. By rotating the control sleeve 6, the ball core 4 inside the valve cavity can be rotated, thereby adjusting the direction of the diversion hole 5 to achieve unidirectional diversion and bidirectional diversion.

[0028] like Figure 2 As shown, the outer wall of the threaded rod 7 has equidistantly distributed positioning holes 14. A positioning pin 15 is inserted into the top of the outer wall of the control sleeve 6. The positioning pin 15 is adapted to the positioning hole 14. The outer wall of the positioning pin 15 is covered with a friction sleeve adapted to it. After the sealing cover 8 is adjusted, the positioning pin 15 is inserted into the corresponding positioning hole 14 to fix the threaded rod 7 and prevent the threaded rod 7 from rotating when the control sleeve 6 is rotated.

[0029] like Figure 1 As shown, flanges 16 are provided at the ends of both the conveying pipe 2 and the branch pipe 3. The flanges 16 are adapted to the conveying pipe 2 and the branch pipe 3 respectively. A sealing ring 17 adapted to the flange 16 is provided on the outer wall of the flange 16. The thickness of the sealing ring 17 is less than the thickness of the flange 16. The flange 16 is easy to connect to the pipeline. The sealing ring 17 seals the pipeline connection to prevent leakage.

[0030] The working principle of this practical application is as follows:

[0031] During operation, the delivery pipe 2 and the diversion pipe 3 are connected to the pipeline for medium transportation. Since the ball core 4 has diversion holes 5 on three sides and at the bottom, the medium enters the ball core 4 through the diversion hole 5 at the bottom. If the opposing diversion holes 5 on both sides of the ball core 4 correspond to the diversion pipes 3 on both sides, the medium can flow towards the diversion pipes 3. If the medium needs to flow only along one side of the diversion pipe 3, simply rotate the ball core 4 so that the opposing diversion holes 5 are inside the valve cavity, aligning the diversion hole 5 on one side with the diversion pipe 3 that needs to be transported. At this time, since the other opposing diversion holes 5 on both sides are blocked inside the valve body 1, the medium can only flow through the bottom of the ball core 4 and the diversion hole 5 on one side, achieving unidirectional medium transportation. During the medium transportation process, the gas-phase silica gel material provides protection. The gasket 9 protects the inside of the diversion hole 5. Due to the high tear resistance and corrosion resistance of the fumed silica, it can reduce the wear and corrosion of the ball core 4 by the medium, making the ball core 4 more durable and improving the service life of the three-way ball valve. When the medium needs to flow between the two diversion pipes 3, it is only necessary to lower the sealing cover 8 and merge it with the diversion hole 5 at the bottom of the ball core 4, so that the sealing cover 8 seals the bottom diversion hole 5. Compared with the traditional three-way ball valve, by setting the protective gasket 9 to protect the inside of the ball core 4, it is not easy to wear. At the same time, the sealing cover 8 is connected to the bottom of the ball core 4, which can enable the medium to flow between the two diversion pipes 3 without backflow. By rotating the control sleeve 6, the ball core 4 inside the valve cavity can be rotated, thereby adjusting the direction of the diversion hole 5 to achieve unidirectional diversion and bidirectional diversion.

[0032] When the sealing cover 8 is in motion, rotating the threaded rod 7 will cause the sealing cover 8 to rise or fall, making it more convenient to use. When the sealing cover 8 is combined with the diversion hole 5, the sealing gasket 10 fills the surrounding gaps, improves airtightness, and prevents media leakage. After the sealing cover 8 is adjusted, the positioning pin 15 is inserted into the corresponding positioning hole 14 to fix the threaded rod 7, preventing the threaded rod 7 from rotating when the control sleeve 6 is rotated.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
