Description
Technical Field
[0001] This invention relates to valve technology, and more particularly to a ball valve structure used in air conditioning refrigeration pipes. Background Technology
[0002] Valves are required on air conditioning refrigeration pipes, and their installation locations vary depending on the operating environment. Currently, these valves simply require rotation to connect or disconnect the internal medium. However, due to their varying locations, these valves need specific safety features to prevent unauthorized operation and thus ensure the smooth flow of refrigerant. Therefore, a ball valve structure that can only be operated by qualified personnel is needed to improve valve safety and prevent accidents. Summary of the Invention
[0003] To address the shortcomings of the existing technology, this invention proposes a ball valve structure for use in air conditioning refrigeration pipes.
[0004] A ball valve structure for use in air conditioning refrigeration pipes includes:
[0005] The valve body consists of a main body and a first connecting pipe and a second connecting pipe disposed on both sides of the main body. An installation area is formed in the middle of the main body, and the installation area has an opening at the lower end.
[0006] A sphere is placed within the installation area, a sealing gasket is provided on the sphere, and a fixing member is provided at the lower end. The fixing member is connected to the main body to restrict the position of the sphere.
[0007] A housing is mounted on the main body. The housing has a handle, a movable component, a positioning component, and multiple rotating components in the middle. The positioning component has multiple slots. The rotating components are hinged within these slots via hinge rods. The movable component is located in the middle of the positioning component and at the lower end of the handle. A rod is located at the lower end of the handle, passing through the movable component and the positioning component to engage with a ball. A cross-shaped component is located at the lower end of the rod. The ball has a cross-shaped groove that engages with the cross-shaped component. A permanent magnet is located in the middle of the movable component, and the rod is positioned within the permanent magnet. A spring is located between the movable component and the handle, sleeved around the rod and the permanent magnet. The handle has a positioning hole that engages with the rotating components.
[0008] A strong magnet is provided in the middle of the handle. When the strong magnet is placed in the middle of the handle, it attracts a permanent magnet, which drives the movable part to compress the spring and approach the handle. The movable part drives the rotating part to rotate around the hinge rod, keeping the rotating part disengaged from the positioning hole. Pressing the handle keeps the cross part in the cross groove. Rotating the handle changes the position of the ball.
[0009] In this invention, the installation area is provided with symmetrically arranged limiting arc grooves, the sealing gasket is provided with an arc groove corresponding to the position of the limiting arc groove, and the sphere is provided with a first limiting rod and a second limiting rod, the first limiting rod and the second limiting rod being placed in different arc grooves and limiting arc grooves.
[0010] In this invention, a clearance area is formed in the middle of the shell. The upper end of the clearance area is provided with a first through hole and the lower end is provided with a second through hole. The inner diameter of the first through hole is smaller than the inner diameter of the second through hole, and the inner diameter of the second through hole is smaller than the inner diameter of the clearance area.
[0011] In this invention, the handle is composed of a hexagonal part and a column. The lower end of the column is provided with a cylindrical body. A cavity is formed in the middle of the cylindrical body. The positioning hole is provided at the connection between the column and the cylindrical body and communicates with the cavity. The rod is provided in the cavity and the lower end of the rod is provided with a hexagonal hole.
[0012] In this invention, the cross-shaped component is composed of a hexagonal prism and a cross-shaped body, with a countersunk hole formed in the middle of the cross-shaped body, and a first bolt disposed in the countersunk hole.
[0013] In this invention, the movable component is composed of a first movable body and a second movable body. The diameter of the first movable body is larger than the diameter of the second movable body. A fixing hole and a third through hole are formed in the middle of the movable component. The fixing hole is located at the upper end of the third through hole. The movable component is also provided with a plurality of guide grooves in the middle. The guide grooves are located around the fixing hole and the third through hole.
[0014] In this invention, the rotating member consists of a rotating part and a first rotating arm and a second rotating arm disposed on the rotating part. The first rotating arm is kept vertically disposed, and the second rotating arm is kept inclined.
[0015] In this invention, the first rotating arm is provided with a positioning end that cooperates with the positioning hole, and the second rotating arm is provided with a guide end that cooperates with the guide groove.
[0016] In this invention, the positioning member has a mounting hole and a fourth through hole in the middle, the inner diameter of the fourth through hole is smaller than the inner diameter of the mounting hole, the mounting hole has a support surface in the middle, and the support surface is provided with a support protrusion.
[0017] In this invention, the sphere is composed of a cover and a tube. The tube is located in the middle of the cover. The middle of the cover is hollowed out to form a collection chamber. The cover is provided with a first guide hole and a second guide hole. The tube is connected to the first guide hole.
[0018] The ball valve structure used in this air conditioning refrigeration pipeline, as described in this invention, has the following advantages: The ball valve structure employs a strong magnetic component in conjunction with a handle. The strong magnetic component changes the position of the moving part, causing it to guide the rotating part to rotate. This ensures that the positioning end on the rotating part does not restrict the handle's position, allowing it to be pressed down and engage with the ball, thus opening or closing the flow of the medium within the valve body. This prevents unauthorized personnel from operating the valve and ensures a stable flow of the air conditioning refrigerant, improving the overall safety performance of the valve structure.

Detailed Implementation
[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0036] like Figures 1 to 15As shown, the ball valve structure used in this air conditioning refrigeration pipe of the present invention includes a valve body 1, a ball 2, a housing 3, a handle 4, a movable part 5, a positioning part 6, and multiple rotating parts 7. The ball 2 is disposed inside the valve body 1. When the angle of the ball 2 changes, the flow direction of the medium inside the valve body 1 changes, allowing the medium inside the valve body 1 to flow into the first connecting pipe 8 or the second connecting pipe 9. The housing 3 is disposed at the upper end of the ball 2 and is fixed to the valve body 1 by a second bolt 10. Part of the handle 4 is located outside the housing 3, and part is located inside the housing 3. The movable part 5 is located at the lower end of the handle 4 and in the middle of the positioning part 6, while the positioning part 6 is located inside the housing 3. The rotating parts 7 are hinged to the positioning part 6. The positioning part 6 is restricted in position by the housing 3, preventing it from moving, but it can rotate. Since both the handle 4 and the movable part 5 are located in the middle of the positioning part 6, the handle 4 can be rotated to drive the movable part 5 and the positioning part 6 to rotate inside the housing 3 when the cross part 11 is not in contact with the cross groove 12. However, the handle 4 cannot be pressed down, so the cross groove 12 cannot be in contact with the cross part 11, and thus the ball 2 cannot be driven to rotate in the installation area 13 by the handle 4.
[0037] The valve body 1 consists of a main body 14 and a first connecting pipe 8 and a second connecting pipe 9 disposed on both sides of the main body 14. An installation area 13 is formed in the middle of the main body 14. The first connecting pipe 8 and the second connecting pipe 9 are both connected to the installation area 13. The installation area 13 is designed with an opening at the lower end.
[0038] The mounting area 13 has an internal thread 15, while the fastener 22 has an external thread 16 that mates with the internal thread 15.
[0039] The sphere 2 is composed of a cover 17 and a tube 18. The tube 18 is located in the middle of the cover 17. The middle of the cover 17 is hollowed out to form a collection chamber 19. The cover 17 is provided with a first guide hole 20 and a second guide hole 21. The tube 18 is connected to the first guide hole 20.
[0040] The first connecting pipe 8 is connected to the first guide hole 20, and the second connecting pipe 9 is connected to the second guide hole 21. Since the included angle between the first connecting pipe 8 and the second connecting pipe 9 is 180°, while the included angle between the first guide hole 20 and the second guide hole 21 is less than 180°, when the first guide hole 20 is connected to the first connecting pipe 8, the second guide hole 21 and the second connecting pipe 9 remain separated. Therefore, the medium in the first connecting pipe 8 enters the collecting chamber 19 and then exits from the middle of the fixing member 22.
[0041] A fifth through hole 23 is provided in the installation area 13, and a rotating body 24 is provided on the sphere 2, and the cross groove 12 is provided on the rotating body 24.
[0042] The sphere 2 is set in the installation area 13. A sealing gasket 25 is provided on the sphere 2, and a fixing member 22 is provided at the lower end. The fixing member 22 is connected to the main body 14 to restrict the position of the sphere 2.
[0043] A symmetrically arranged limiting arc groove 26 is provided in the installation area 13. The sealing gasket 25 is provided with an arc groove 27 corresponding to the position of the limiting arc groove 26. The sphere 2 is provided with a first limiting rod 28 and a second limiting rod 29, which are placed in different arc grooves 27 and limiting arc grooves 26. A sixth through hole 66 is provided in the middle of the sealing gasket 25.
[0044] The first limiting rod 28 and the second limiting rod 29 are used to limit the rotation angle of the ball 2. For example... Figure 12 As shown, when the first limiting rod 28 is at the M end of the arc groove 27, the second limiting rod 29 is at the N end. When the first limiting rod 28 is at the end away from the M end, the second limiting rod 29 is at the end away from the N end.
[0045] The housing 3 is mounted on the main body 14. A handle 4, a movable component 5, a positioning component 6, and multiple rotating components 7 are located in the middle of the housing 3. The positioning component 6 has multiple opening slots 30, and the rotating components 7 are hinged within these slots via hinge rods 31. The movable component 5 is located in the middle of the positioning component 6 and is positioned below the handle 4.
[0046] The lower end of the handle 4 has a rod 32, which passes through the movable part 5 and the positioning part 6 and engages with the ball 2. The lower end of the rod 32 has a cross part 11, and the ball 2 has a cross groove 12 that engages with the cross part 11. A permanent magnet 33 is located in the middle of the movable part 5, and the rod 32 is located in the middle of the permanent magnet 33. A spring 34 is located between the movable part 5 and the handle 4, and the spring 34 is sleeved on the outside of the rod 32 and the permanent magnet 33. The handle 4 has a positioning hole 35 that engages with the rotating part 7. A through hole 36 is formed in the middle of the permanent magnet 33, and the rod 32 is inserted into the through hole 36 and can move within the through hole 36.
[0047] A strong magnet 37 is provided in the middle of the handle 4, and a placement hole 38 is provided in the middle of the handle 4. The strong magnet 37 is placed in the placement hole 38. When the strong magnet 37 is placed in the middle of the handle 4, it attracts the permanent magnet 33, which drives the movable part 5 to compress the spring 34 and move it closer to the handle 4. The movable part 5 drives the rotating part 7 to rotate around the hinge rod 31, keeping the rotating part 7 disengaged from the positioning hole 35. Pressing the handle 4 keeps the cross part 11 in the cross groove 12. Rotating the handle 4 changes the position of the ball 2.
[0048] The strong magnetic component 37 can be removed and stored when needed. That is, when the ball 2 does not need to be rotated, the strong magnetic component 37 can be removed separately, instead of being kept in the center of the handle 4. Of course, it can also be used depending on the usage environment; it can be placed in the handle 4 or removed and stored separately. When the strong magnetic component 37 is removed and stored separately, the handle 4 cannot be pressed when the ball 2 needs to be rotated, providing a safety protection effect. This prevents unauthorized personnel from rotating the handle 4 when the valve body 1 is placed outdoors, causing the ball 2 to rotate and thus disrupting the flow of the medium, thus achieving a safety protection effect.
[0049] A clearance area 39 is formed in the middle of the housing 3. A first through hole 40 is provided at the upper end of the clearance area 39, and a second through hole 41 is provided at the lower end. The inner diameter of the first through hole 40 is smaller than the inner diameter of the second through hole 41, and the inner diameter of the second through hole 41 is smaller than the inner diameter of the clearance area 39. The column 42 is disposed in the first through hole 40, and the positioning member 6 is disposed in the second through hole 41.
[0050] The clearance area 39 is used so that when the rotating part 7 rotates, the positioning end 43 moves out of the positioning hole 35, and then the first rotating arm 44 is kept rotating around the hinge rod 31, so that the first rotating arm 44 drives the positioning end 43 into the clearance area 39. At this time, the positioning hole 35 is not restricted by the positioning end 43, and the handle 4 can be pressed down, so that the cross part 11 at the lower end of the handle 4 can engage with the cross groove 12, and the ball 2 can be rotated while the handle 4 is rotated.
[0051] The handle 4 is composed of a hexagonal part 45 and a column 42. The lower end of the column 42 is provided with a cylindrical body 46, and a cavity 47 is formed in the middle of the cylindrical body 46. A positioning hole 35 is provided at the connection between the column 42 and the cylindrical body 46, and the positioning hole 35 communicates with the cavity 47. The rod 32 is provided in the cavity 47, and the lower end of the rod 32 is provided with a hexagonal hole 48.
[0052] The cross component 11 consists of a hexagonal prism 49 and a cross body 50. A countersunk hole 51 is formed in the middle of the cross body 50, and a first bolt 52 is installed in the countersunk hole 51. The first bolt 52 connects the cross component 11 to the lower end of the rod body 32.
[0053] The movable component 5 consists of a first movable body 53 and a second movable body 54. The diameter of the first movable body 53 is larger than the diameter of the second movable body 54. A fixing hole 55 and a third through hole 56 are formed in the middle of the movable component 5. The fixing hole 55 is located at the upper end of the third through hole 56. Multiple guide grooves 57 are also provided in the middle of the movable component 5, and the guide grooves 57 are located around the fixing hole 55 and the third through hole 56. The first movable body 53 is located inside the chamber 47.
[0054] The rotating component 7 consists of a rotating part 58 and a first rotating arm 44 and a second rotating arm 59 disposed on the rotating part 58. The first rotating arm 44 is kept vertically disposed, and the second rotating arm 59 is kept inclined. The first rotating arm 44 is provided with a positioning end 43 that mates with the positioning hole 35, and the second rotating arm 59 is provided with a guide end 60 that mates with the guide groove 57.
[0055] Its guide groove 57 is inclined, so when the guide end 60 is in the inclined guide groove 57, the guide end 5 can move the guide groove 57 upward during the upward movement of the movable part 5, thereby causing the guide end 60 to gradually leave the guide groove 57, pushing the guide end 60, causing the rotating part 7 to rotate around the hinge rod 31, keeping the positioning end 43 from leaving the positioning hole 35 and entering the avoidance area 39.
[0056] The positioning member 6 has a mounting hole 61 and a fourth through hole 62 in the middle. The inner diameter of the fourth through hole 62 is smaller than the inner diameter of the mounting hole 61. A support surface 63 is formed in the middle of the mounting hole 61, and a support protrusion 64 is provided on the support surface 63. The support surface 63 is used to prevent the handle 4 from moving further down. When the handle 4 is not pressed down, there is a gap between the support surface 63 and the handle 4, and a pressing gap 65 exists between the housing 3 and the hexagonal part 45. When the cross member 11 and the cross groove 12 make contact, the gap disappears, and the pressing gap 65 also disappears.
[0057] The support protrusion 64 is used to support the first movable body 53 on the movable part 5, while the second movable body 54 is located in the fourth through hole 62, and the inner diameter of the mounting hole 61 is larger than the diameter of the first movable body 53.
[0058] When rotation is required, the strong magnetic component 37 is placed in the placement hole 38, causing the strong magnetic component 37 to attract the permanent magnet 33. The permanent magnet 33 then moves the movable component 5 upwards towards the handle 4, compressing the spring 34. This guides the guide end 60 inside the movable component 5, causing the rotating component 7 to rotate around the hinge rod 31. The positioning end 43 disengages from the positioning hole 35 and enters the clearance area 39, no longer restricting the downward movement of the handle 4. At this time, the handle 4 can be pressed, causing the cross component 11 and the cross groove 12 to engage. When the handle 4 is rotated, the ball 2 can be rotated, changing the direction of the medium flow.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
