Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a ball valve that is easy to disassemble and assemble. Background Technology

[0002] A ball valve is a pipeline control valve with a ball with a through hole as its core opening and closing element. It is widely used in fluid transportation systems. Its core structure includes a valve body, a ball, a valve stem, and a sealing assembly. Rotating the valve stem drives the ball to rotate. When the through hole of the ball is aligned with the flow channel of the valve body, the fluid flows smoothly. When the through hole is completely misaligned with the flow channel, the flow is cut off in the pipeline. It opens and closes quickly and has the advantages of low flow resistance, reliable sealing, and convenient operation. It can be used for water, oil, gas, and some corrosive media and is commonly used in petroleum, chemical, municipal water supply and drainage, and HVAC fields.

[0003] A ball valve with publication number CN223035736U that is easy to disassemble includes a first valve body, a second valve body, and a ball. The middle part of the bottom surface of the first valve body is rotatably connected to the ball. A connecting mechanism is provided at the front end of the first valve body. The connecting mechanism includes a first fixing ring and a second fixing ring. Inner connecting blocks are fixedly connected to all four sides of the front end of the inner wall of the first valve body. Inner connecting grooves are opened at all four sides of the rear end of the outer wall of the second valve body. The inner connecting grooves are snapped into the inner connecting blocks. Outer connecting blocks are fixedly connected to the upper and lower ends of the outer wall of the front end of the first fixing ring.

[0004] In the aforementioned existing device, a bidirectional threaded rod is used to connect the first fixing ring and the limiting block. This connection structure requires external tools during disassembly and assembly, which increases the complexity of the operation. At the same time, its key bolt-type connection parts are directly exposed to the external environment, and are prone to corrosion due to contact with moisture and impurities in the air during long-term use. This reduces the overall disassembly and assembly efficiency of the ball valve, making it difficult to meet the practical application requirements for convenient and efficient disassembly and assembly. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing technologies that use bidirectional threaded rod connections, require external tools for disassembly and assembly, are cumbersome to operate, and expose key bolt-type connection parts, which are prone to corrosion due to contact with moisture and impurities after long-term use, resulting in reduced disassembly and assembly efficiency of ball valves and failing to meet the actual needs for convenient and efficient disassembly and assembly. Therefore, this utility model proposes an easy-to-disassemble ball valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ball valve that is easy to disassemble and assemble includes a ball valve body and two water pipes. Two first sealing rings and second sealing rings are installed on the inner wall of the ball valve body. Two second connecting rings are fixedly connected to the outer surface of the ball valve body. First connecting rings are fixedly connected to the outer surfaces of the two water pipes. Two connecting rods are fixedly connected to the outer surfaces of the two first connecting rings. A first quarter-circular plate is fixedly connected to one end of each connecting rod. Two limiting boxes are installed inside the rings of the two second connecting rings. Each limiting box has a connected horizontal slot and a vertical slot inside. The outer surface of each first quarter-circular plate is slidably connected to the horizontal slot. An ejection mechanism is provided inside each horizontal slot, and a limiting mechanism is provided inside each vertical slot. At least four reinforcing mechanisms are provided on the outside of the two second connecting rings.

[0008] Preferably, the limiting mechanism includes a second quarter circular plate, the outer surface of which is slidably connected to the vertical slot, and the outer surface of which abuts against the connecting rod and the first quarter circular plate.

[0009] Preferably, a pull rod is fixedly connected to the top of the second quarter circular plate, the outer surface of the pull rod is slidably connected to the limiting box, and a pull plate is fixedly connected to the top of the pull rod.

[0010] Preferably, a second spring is sleeved on the outer surface of the pull rod, and the two ends of the second spring are fixedly connected to the inner top wall of the vertical slot and the upper surface of the second quarter circular plate.

[0011] Preferably, the ejection mechanism includes an ejection plate and a first spring. The outer surface of the ejection plate is slidably connected to the transverse slot. One end of the ejection plate abuts against the first quarter circular plate. One end of the first spring is fixedly connected to the ejection plate, and the other end of the first spring is fixedly connected to the inner sidewall of the transverse slot.

[0012] Preferably, the reinforcing mechanism includes a carrier groove, which is fixedly connected to the second connecting ring, and a rotating L-plate is rotatably connected to the inner wall of the carrier groove.

[0013] Preferably, a rubber abutment is fixedly connected to the outer surface of the rotating L-plate, and the rubber abutment abuts against the first connecting ring.

[0014] Compared with the prior art, this utility model provides an easy-to-disassemble ball valve, which has the following advantages:

[0015] 1. This utility model uses a first connecting ring to fix the connecting rod and the first quarter circular plate, which cooperates with the horizontal slot of the upper limit box of the second connecting ring. Relying on the second quarter circular plate, pull rod, pull plate and second spring of the limiting mechanism, it achieves the limitation without external tools. The ejection plate of the ejection mechanism and the first spring assist in separation. Moreover, the key connecting components are built into the limiting box and are not exposed. This solves the problem that existing devices require tools and are prone to corrosion, resulting in low disassembly and assembly efficiency, and improves the convenience and efficiency of disassembly and assembly.

[0016] 2. This utility model enhances the sealing fit with the water pipe by using the first sealing ring and the second sealing ring on the inner wall of the ball valve body; and further strengthens the radial support by using the carrier groove, rotating L plate and rubber abutment of the reinforcing mechanism to press against the first connecting ring, reducing the stress deformation of the connection part, and ensuring the connection stability and sealing reliability of the ball valve during use.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A ball valve that is easy to disassemble and assemble includes a ball valve body 1 and two water pipes 2. The inner wall of the ball valve body 1 is equipped with two first sealing rings 3 and second sealing rings 4. The double sealing rings can improve the sealing reliability between the ball valve body 1 and the water pipes 2. The outer surface of the ball valve body 1 is fixedly connected with two second connecting rings 6. The outer surface of the two water pipes 2 is fixedly connected with a first connecting ring 5. The cooperation between the first connecting ring 5 and the second connecting ring 6 can provide an installation basis for convenient disassembly and assembly.

[0025] Two connecting rods 20 are fixedly connected to the outer surfaces of the two first connecting rings 5. One end of each connecting rod 20 is fixedly connected to a first quarter circular plate 10. The connecting rods 20 allow the first quarter circular plate 10 to extend a certain distance on the first connecting ring 5, which facilitates the second quarter circular plate 13 to limit its position. Two limiting boxes 7 are installed inside the ring bodies of the two second connecting rings 6. Each limiting box 7 has a connected horizontal slot 8 and a vertical slot 9 inside. The outer surface of each first quarter circular plate 10 is slidably connected to the horizontal slot 8. The horizontal slot 8 and the vertical slot 9 cooperate to provide a spatial basis for the limiting.

[0026] Each vertical slot 9 is equipped with a limiting mechanism inside. The limiting mechanism includes a second quarter circular plate 13. The outer surface of the second quarter circular plate 13 is slidably connected to the vertical slot 9. The outer surface of the second quarter circular plate 13 abuts against the connecting rod 20 and the first quarter circular plate 10. The abutment of the second quarter circular plate 13 can restrict the axial disengagement of the first quarter circular plate 10.

[0027] A pull rod 14 is fixedly connected to the top of the second quarter-circular plate 13. The outer surface of the pull rod 14 is slidably connected to the limiting box 7. A pull plate 15 is fixedly connected to the top of the pull rod 14, which facilitates manual operation of the pull rod 14 to control the limiting mechanism. A second spring 16 is sleeved on the outer surface of the pull rod 14. The two ends of the second spring 16 are fixedly connected to the inner top wall of the vertical slot 9 and the upper surface of the second quarter-circular plate 13. Figure 3 When in the natural state, the second spring 16 can drive the second quarter circular plate 13 to automatically reset.

[0028] Each transverse slot 8 is equipped with an ejection mechanism, which includes an ejection plate 11 and a first spring 12. The ejection mechanism assists the first quarter-circular plate 10 in disengaging from the transverse slot 8. The outer surface of the ejection plate 11 is slidably connected to the transverse slot 8, one end of the ejection plate 11 abuts against the first quarter-circular plate 10, one end of the first spring 12 is fixedly connected to the ejection plate 11, and the other end of the first spring 12 is fixedly connected to the inner wall of the transverse slot 8. Figure 3 In the compressed state, the first spring 12 provides a pushing force to the ejector plate 11.

[0029] At least four reinforcing mechanisms are provided on the outside of each of the two second connecting rings 6. The reinforcing mechanism includes a carrier 17, which is fixedly connected to the second connecting ring 6. A rotating L-plate 18 is rotatably connected to the inner wall of the carrier 17. The carrier 17 provides stable rotational support for the rotating L-plate 18. The rotating L-plate 18 can assist in resisting the lateral impact force of the water flow on the outside, greatly reducing the stress deformation of the components at the joint between the first connecting ring 5 and the second connecting ring 6. A preset friction force is provided between the mating surfaces of the carrier 17 and the rotating L-plate 18 to prevent the rotating L-plate 18 from rotating automatically in the non-operating state and to prevent it from losing its auxiliary reinforcing effect on the first connecting ring 5.

[0030] A rubber abutment 19 is fixedly connected to the outer surface of the rotating L plate 18. The rubber abutment 19 abuts against the first connecting ring 5. The rubber abutment 19 can reduce the wear on the first connecting ring 5 during the abutment.

[0031] Working principle: When the water pipe 2 is aligned with the interface of the ball valve body 1 and pushed, the first connecting ring 5 drives the connecting rod 20 and the first quarter plate 10 to insert into the horizontal slot 8 of the upper limit box 7 of the second connecting ring 6. The first quarter plate 10 pushes the second quarter plate 13 in the vertical slot 9 to slide upward, compressing the second spring 16. After the first quarter plate 10 slides past the second quarter plate 13, the second spring 16 pushes it back to its original position and limits it, preventing the first quarter plate 10 from coming out and achieving axial fixation. The first sealing ring 3 and the second sealing ring 4 of the ball valve body 1 are in close contact with the water pipe 2 for sealing. Rotating the rotating L plate 18 on the carrier 17 causes the rubber abutment 19 to press against the first connecting ring 5, enhancing radial support.

[0032] Rotate L plate 18 in the opposite direction to disengage rubber abutment 19 from first connecting ring 5, pull pull plate 15, drive pull rod 14 and second quarter circular plate 13 to slide upward to compress second spring 16, release the limit, first spring 12 pushes push out plate 11, pushes first quarter circular plate 10, connecting rod 20 and first connecting ring 5 out of horizontal slot 8, pull water pipe 2 to complete separation.
