DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the present application provides an easy-to-maintain ball valve, which solves the problem that the ball valve in the prior art is usually directly connected to the pipeline through a flange. When the ball valve fails, the disassembly and maintenance process of the ball valve is inconvenient and multiple sets of bolts need to be unscrewed for operation, which is time-consuming and labor-intensive. It is impossible to quickly replace and maintain the faulty ball valve on the pipeline, thereby reducing the working efficiency of the on-site equipment and increasing the inspection and maintenance time.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses an easy-to-maintain ball valve. Figure 1-4 As shown, it comprises a ball valve body 1, a clamping block 2 is fixedly connected to the ball valve body 1, a sleeve 3 is sleeved on the outer side of the clamping block 2, and a connecting pipe 4 connected to an external pipeline is fixedly connected to the sleeve 3;

[0029] A clamping slot 201 is provided on the clamping block 2, and a clamping mechanism is provided between the clamping block 2 and the sleeve 3, and the clamping mechanism includes:

[0030] A supporting and fixing block 5 is arranged and fixed on the sleeve 3;

[0031] The guide rail rod 501 is arranged and fixed on the supporting fixed block 5;

[0032] The double-threaded screw rod 502 is rotatably connected to the supporting fixed block 5;

[0033] The adjusting platform 503 is arranged on the guide rail rod 501 and is slidably connected thereto. The adjusting platform 503 is threadedly connected to the double-threaded lead screw 502;

[0034] The wedge block 504 is disposed on the adjustment platform 503 .

[0035] Furthermore, a sealing gasket 301 is provided inside the sleeve 3, and the sealing gasket 301 is clamped between the sleeve 3 and the block 2. The provided sealing gasket 301 can ensure a good sealing effect between the sleeve 3 and the block 2, so that the connection between the ball valve body 1 and the block 2 is stable when docking with the sleeve 3 and the connecting pipe 4.

[0036] The double-threaded screw rod 502 is provided with a rotating handle 5021 , and the rotating handle 5021 makes the double-threaded screw rod 502 easy to rotate and saves effort.

[0037] The adjusting platform 503 is provided with a threaded hole 5031 corresponding to the double-threaded screw rod 502 , and the adjusting platform 503 is provided with a round hole corresponding to the guide rail rod 501 .

[0038] A slot corresponding to the wedge block 504 is provided on the sleeve 3. The wedge block 504 passes through the slot and is movably engaged in the slot 201. After the wedge block 504 is engaged in the slot 201, the inclined surface of the wedge block 504 abuts against the inner wall of the slot 201. When the wedge block 504 continues to move, the inclined surface of the wedge block 504 applies a lateral thrust to the inner wall of the slot 201, so that the block 2 and the sleeve 3 are tightly engaged and have good sealing.

[0039] The easy-to-maintain ball valve is used to connect the connecting pipe 4 with the external pipeline, so that the ball valve body 1 is connected to the pipeline through the connection method of the ball valve body 1, the clamping block 2, the sleeve 3 and the connecting pipe 4. The ball valve body 1 is clamped with the sleeve 3 through the clamping block 2, and the clamping block 2 and the sleeve 3 are locked by a clamping mechanism. The clamping block 2 and the sleeve 3 are easy to disassemble and assemble. When the ball valve body 1 needs to be maintained, there is no need to disassemble the connecting pipe 4 from the external pipeline, and only the ball valve body 1 and the clamping block 2 need to be disassembled. The ball valve body 1 and the clamping block 2 are easy to disassemble and assemble, so the ball valve body 1 is easy to maintain and meets the use requirements.

[0040] When the block 2 is clamped with the sleeve 3, the block 2 is clamped inside the sleeve 3, and then the handle 5021 is rotated, so that the handle 5021 drives the double-threaded screw 502 to rotate, the double-threaded screw 502 drives the adjusting platform 503 to move, and the adjusting platform 503 drives the wedge block 504 to move. The wedge block 504 is finally clamped in the clamping groove 201, so that the block 2 is squeezed inside the sleeve 3 to achieve sealing. Therefore, the clamping of the block 2 and the sleeve 3 is completed, ensuring the convenient installation of the ball valve body 1, and the subsequent disassembly process can be the opposite of the above process.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
