Description
Technical Field
[0001] The utility model belongs to the technical field of valve design, and specifically relates to a high-pressure three-way reversing ball valve structure. Background Art
[0002] Valves are essential key components in fluid control systems; they are like the "switches" of pipelines, controlling the flow of fluids; there is a rich variety of valves. Globe valves can precisely regulate the flow rate, gate valves are labor-saving in opening and closing, butterfly valves are flexible in operation, and their materials are diverse to adapt to different environments, such as stainless steel being corrosion-resistant and cast iron being economical and practical; valves work silently in many fields such as industry, construction, and energy, ensuring that fluids are transported as needed and guaranteeing the safe and efficient operation of the system. Existing valves generally use a reversing ball valve structure for turning operations between pipelines in the use of three-way pipelines.
[0003] The reversing ball valve mainly consists of a valve body, a valve ball, a valve stem, a seal, and a driving device; the valve body is a solid outer shell; the valve ball is round with specific channels on its surface; the valve stem connects the valve ball and transmits power; the seal ensures a tight fit to prevent leakage; its principle is that the driving device drives the valve stem to rotate the valve ball; when the valve ball channel is in line with the pipeline direction, the fluid flows smoothly through; rotating the valve ball to change the channel direction can achieve the switching of the flow direction; in chemical production, an electrically driven reversing ball valve can accurately and quickly change the material flow direction, meet complex process requirements, and ensure the efficient and stable operation of production.
[0004] When the existing reversing ball valve structure is in use, there will be a situation of insufficient sealing, which will lead to liquid leakage or gas leakage at the reversing point during use. This will not only cause waste of resources but also may pose a threat to the production space and the safety of operators; moreover, the existing reversing ball valve structure has deficiencies in the joint locking structure, which may lead to pipeline offset during transportation. Therefore, a high-pressure three-way reversing ball valve structure is proposed to address the above problems. Summary of the Utility Model
[0005] In order to make up for the deficiencies of the existing technology and address the problems existing in the existing equipment, the utility model proposes a high-pressure three-way reversing ball valve structure.
[0006] The technical solution adopted by the present utility model to solve its technical problems is a high-pressure three-way reversing ball valve structure, including a top bead. A first handle is provided on the top side of the connection box. The bottom end of the first handle is welded and connected to a transmission rod. The transmission rod passes through the connection box and is welded and connected to the top end of the ball valve body. Spherical holes are opened on both sides of the ball valve body. A three-way hole is opened inside the ball valve body. A bayonet is provided at the port of the three-way hole inside the ball valve body. A stepped plate is welded and connected inside the bayonet. An outlet is opened inside the stepped plate. The ports of the bayonet are respectively communicated with a second connecting pipe, a first connecting pipe, and a third connecting pipe. One ends of the third connecting pipe, the second connecting pipe, and the first connecting pipe are communicated with the inside of the connection box. Inlets are provided at the other ends of the second connecting pipe, the first connecting pipe, and the third connecting pipe. A circular hole is provided inside the connection box. A spring is welded and connected inside the circular hole inside the connection box. The other end of the spring is welded and connected to the top bead. The diameter of the top bead is the same as the diameter of the spherical hole on one side of the ball valve body. With this structural design, the switching between pipelines can be realized by rotating the first handle, and the stepped design at the port of the ball valve can make the structure relatively sealed to increase the sealing performance of the structure.
[0007] Preferably, a second handle is provided at the top end of the second connecting pipe. A transmission gear is welded and connected to the bottom of the second handle. The transmission gear is meshed and connected to a transmission ring. A gear groove is opened on one side of the transmission ring. A positioning groove is provided inside the transmission ring. A threaded hole is provided inside the positioning groove. A sliding ring is rotatably connected inside the positioning groove. A spiral thread is provided on the outside of the sliding ring. The spiral thread has the same diameter as the threaded hole inside the positioning groove. By adding a locking structure inside the structure, by rotating the second handle, the gear drives the transmission ring, and the transmission ring drives the sliding ring to rotate, thereby extending the structure into the connection box, thereby fixing the channel inside the ball valve, thereby increasing the stability and sealing performance of the structure, thereby avoiding the situation of liquid leakage and air leakage during use, which may affect the production space and operators; and this structure avoids the problem of pipeline offset caused by unstable joint locking.
[0008] Preferably, an annular hole is opened on one side of the second connecting pipe close to the transmission gear. Ten limiting rods are provided inside the annular hole inside the second connecting pipe. The limiting rods are located inside the positioning groove. The inside of the sliding ring is provided with a structure identical to that of the transmission ring, and its structure is stepped. The stepped surface of the stepped plate is relatively closed to this structure. By adding the design of limiting rods inside the pipeline, the stability of the structure operation can be increased.
[0009] The beneficial effects of the present utility model are as follows:
[0010] This utility model increases a locking pin structure inside the structure. By rotating the second handle, the gear drives the transmission ring, and the transmission ring drives the sliding ring to rotate, thereby extending the structure into the connection box, fixing the channel inside the ball valve, increasing the stability and sealing performance of the structure, and avoiding the situation of liquid leakage and air leakage during use, which may affect the production space and operators. Moreover, this structure avoids the problem of pipeline offset caused by unstable joint locking. Additionally, by adding the design of top beads inside the device, the feedback during commutation of the structure can be increased, improving the accuracy of the structure while enhancing its stability.

[0019] Please refer to Figures 1-5 As shown, a high-pressure three-way reversing ball valve structure includes a connection box 1. A first handle 2 is provided on the top side of the connection box 1. The bottom end of the first handle 2 is welded and connected to a transmission rod 3. The transmission rod 3 passes through the connection box 1 and is welded and connected to the top end of a ball valve body 11. Spherical holes 15 are formed on both sides of the ball valve body 11. A three-way hole is formed inside the ball valve body 11. A bayonet 12 is provided at the port of the three-way hole inside the ball valve body 11. A stepped plate 13 is welded and connected inside the bayonet 12. An outlet 14 is formed inside the stepped plate 13. The ports of the bayonet 12 are respectively communicated with a second connecting pipe 6, a first connecting pipe 5, and a third connecting pipe 8. One ends of the third connecting pipe 8, the second connecting pipe 6, and the first connecting pipe 5 are communicated with the inside of the connection box 1. The other ends of the second connecting pipe 6, the first connecting pipe 5, and the third connecting pipe 8 are provided with inlets 7. A circular hole is provided inside the connection box 1. A spring 9 is welded and connected inside the circular hole inside the connection box 1. The other end of the spring 9 is welded and connected to a top bead 10. The diameter of the top bead 10 is the same as the diameter of the spherical hole 15 on one side of the ball valve body 11. When using this structure for reversing operation, at this time, the operator connects the pipelines to the inlets 7 of the second connecting pipe 6, the first connecting pipe 5, and the third connecting pipe 8 in sequence, and then starts production. When turning is required, at this time, the operator rotates the first handle 2. At this time, the first handle 2 drives the transmission rod 3, and the transmission rod 3 drives the ball valve body 11 below to rotate. At this time, the top bead 10 located inside the connection box 1 starts to sink, and when it reaches another bayonet 12, the spring 9 pushes the top bead 10 into the bayonet 12. At this time, the operator judges whether the connection is successful through the feedback of the top bead 10, thereby completing the reversing operation.
[0020] The top of the second connecting pipe 6 is provided with a second handle 4. The bottom of the second handle 4 is welded to connect a transmission gear 16. The transmission gear 16 is meshed with a transmission ring 18. A gear groove 20 is formed on one side of the transmission ring 18. A positioning groove 19 is arranged inside the transmission ring 18, and a threaded hole is arranged inside the positioning groove 19. A spiral thread 22 is rotatably connected inside the positioning groove 19. A sliding ring 21 is arranged outside the spiral thread 22, and the sliding ring 21 has the same diameter as the threaded hole inside the positioning groove 19. An annular hole is formed on one side of the second connecting pipe 6 close to the transmission gear 16. Ten limiting rods 17 are arranged inside the annular hole of the second connecting pipe 6, and the limiting rods 17 are located inside the positioning groove 19. The inside of the spiral thread 22 has the same structure as the transmission ring 18, and its structure is in a stepped shape. The stepped surface of the stepped plate 13 is relatively closed to this structure. When locking the structure, at this time, the operator rotates the second handle 4. At this time, the second handle 4 drives the transmission gear 16 to rotate, and the transmission gear 16 drives the transmission ring 18 to rotate. At this time, the spiral thread 22 inside the transmission ring 18 drives the sliding ring 21 to move forward under the drive of the threaded hole inside the transmission ring 18. In this way, the sliding ring 21 is connected to the stepped plate 13, thereby completing the locking operation.
[0021] Working principle: When using this structure for commutation operation, at this time, the operator sequentially connects the pipelines to the inlets 7 of the second connecting pipe 6, the first connecting pipe 5, and the third connecting pipe 8, and then starts production. When a turn is needed, at this time, the operator rotates the first handle 2. At this time, the first handle 2 drives the transmission rod 3, and the transmission rod 3 drives the ball valve body 11 below to rotate. At this time, the top bead 10 inside the connection box 1 starts to sink, and when it reaches another bayonet 12, the spring 9 pushes the top bead 10 into the bayonet 12. At this time, the operator judges whether the connection is successful through the feedback of the top bead 10, thereby completing the commutation operation. When locking the structure, at this time, the operator rotates the second handle 4. At this time, the second handle 4 drives the transmission gear 16 to rotate, and the transmission gear 16 drives the transmission ring 18 to rotate. At this time, the spiral thread 21 inside the transmission ring 18 drives the sliding ring 21 to move forward under the drive of the threaded hole inside the transmission ring 18. In this way, the sliding ring 21 is connected to the stepped plate 13, thereby completing the locking operation, and then the production operation can be continued.
