When installing the welded ball valve, the welded ball valve can be first placed at the installation position, and then four groups of adjusting screws are rotated simultaneously to drive the base to descend until it closely contacts the installation platform. At this time, the left and right ends of the welded ball valve can be respectively welded and connected to the pipeline, thus more conveniently supporting and fixing the welded ball valve; through this device, it has a built - in fixed support and can very conveniently adjust its own working conditions to improve the installation efficiency of the welded ball valve, thereby enhancing the practicability.

[0005] Regarding the above problems, the existing patent gives a solution.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:

[0028] A large hemispherical valve with an auxiliary installation structure, including a valve body 1, brackets 2 fixedly connected to the surfaces at both ends of the valve body 1, a driving component 3 fixedly connected to the surfaces at both ends of the valve body 1, and an auxiliary component 4 fixedly connected to the output end of the driving component 3;

[0029] The auxiliary component 4 includes an alignment block 401, a guiding rod 402 slidably connected to the inner wall of the alignment block 401, and a U-shaped alignment groove 403 opened at the top of the alignment block 401, and a reinforcement block 404 fixedly connected to the surface of the guiding rod 402.

[0030] In this embodiment: Supported by the bracket 2, it can support the valve body 1, thereby preventing the valve body 1 from being corroded due to contact with the ground. And fixed by the bracket 2 and the reinforcement block 404, the stability of the guiding rod 402 during use can be increased, so that it will not shake during use. Under the guidance of the U-shaped alignment groove 403, it is convenient for the staff to place the pipeline into the U-shaped alignment groove 403. And during the subsequent movement of the alignment block 401, the U-shaped alignment groove 403 can be driven to move with the pipeline placed inside. And limited by the guiding rod 402, the moving position of the alignment block 401 will not deviate. And after the alignment block 401 moves, it can drive the placed pipeline to be docked with both ends of the valve body 1.

[0031] Specifically, as Figure 4 shown, the driving component 3 includes a collar 301, which is fixedly connected to the surfaces at both ends of the valve body 1. The bottom surface of the collar 301 is fixedly connected with a mounting block 302. The front side and the rear side of the mounting block 302 are fixedly connected to the opposite sides of the reinforcement block 404. Mounting holes 303 are opened on both sides of the mounting block 302. The inner wall of the mounting hole 303 is fixedly connected with a hydraulic rod 304. The output end of the hydraulic rod 304 is fixedly connected to the opposite side of the alignment block 401.

[0032] Specifically, as Figure 4 shown, the inner wall of the collar 301 is fixedly connected with a reinforcement washer 5, and there are two reinforcement washers 5 in total.

[0033] Specifically, as Figure 4 shown, the output end of the hydraulic rod 304 is fixedly connected with a protective sleeve 6, and the protective sleeve 6 is made of rubber material.

[0034] In this embodiment: Through the connection between the collar 301 and the mounting block 302, the collar 301 can fix the mounting block 302, increasing the stability of the mounting block 302 during use. And with the cooperation of the mounting block 302 and the mounting hole 303, the hydraulic rod 304 can be fixed, so that the hydraulic rod 304 will not shake during use. And by starting the hydraulic rod 304, it can pull the alignment block 401 through the connection with the alignment block 401, so that the alignment block 401 can drive the pipeline to move through the U-shaped alignment groove 403. And with the setting of the reinforcement washer 5, the connection between the collar 301 and the valve body 1 can be made closer, so that the collar 301 will not shake with the valve body 1. And under the protection of the protective sleeve 6, it can prevent the hydraulic rod 304 from being damaged due to accidental contact between the pipeline and the hydraulic rod 304.

[0035] Specifically, as Figure 5 shown, the inner wall of the U-shaped alignment groove 403 is fixedly connected with an anti-slip pad 7, and the surface of the anti-slip pad 7 is provided with a number of anti-slip bumps.

[0036] Specifically, such as Figure 5 As shown, both ends of the guide rod 402 are fixedly connected to the limiting blocks 8 , which are circular in shape, and the side of the limiting block 8 close to the guide rod 402 contacts the side opposite to the alignment block 401 .

[0037] In this embodiment: the anti-slip bumps on the surface of the anti-slip pad 7 can prevent the pipe from sliding with the U-shaped alignment groove 403, and under the limitation of the limit block 8, the movable range of the alignment block 401 can be limited to avoid the movable range being too large, which will cause the alignment block 401 to separate from the guide rod 402.

[0038] Specifically, such as Figure 2 As shown, both ends of the valve body 1 are fixedly connected with sealing gaskets 9 for use therewith, and there are two sealing gaskets 9 in total.

[0039] Specifically, such as Figure 3 As shown, a clearance groove 10 is provided at the bottom of the bracket 2, and the clearance groove 10 is designed to be square.

[0040] In this embodiment: through the sealing performance of the sealing gasket 9, it can seal the joint between the valve body 1 and the pipeline, thereby avoiding leakage at the joint, and through the give way groove 10, it can provide expansion and contraction space for the hydraulic rod 304, thereby avoiding the hydraulic rod 304 from getting stuck due to insufficient space.

[0041] Working principle: When the valve body 1 needs to be docked with the pipeline, the pipeline can be placed in the U-shaped alignment groove 403, and then the hydraulic rod 304 can be started. After the hydraulic rod 304 is started, the alignment block 401 can be pulled, and when the alignment block 401 moves, the U-shaped alignment groove 403 can be driven to move, so that the pipeline in the U-shaped alignment groove 403 can be close to the valve body 1, and under the limitation of the guide rod 402, the moving position of the alignment block 401 will not be offset, and the hydraulic rod 304 will not shake during use through the fixation of the mounting block 302 and the mounting hole 303. Subsequently, when the pipeline contacts the valve body 1, the docking of the pipeline and the valve body 1 can be completed, and then the staff can install the connecting parts between the pipeline and the valve body 1.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
