[0016] The full-welded ball valve is assembled by welding, and the sealing performance is usually detected after welding. Due to the integrated welding structure, if the sealing performance is poor after welding, subsequent disassembly and maintenance will face great difficulty.

[0017] According to the application, the sealing detection assembly further includes a first lifting telescopic frame, a second lifting frame, a horizontal pushing piece, a sealing plug, a pressurizing barrel, a second lifting telescopic frame and a stop block, the bottom of the first lifting telescopic frame is fixedly connected with the sliding end of the first linear slide rail, the telescopic end of the first lifting telescopic frame is fixedly connected with the upper part of the second lifting frame, the lifting end of the second lifting frame is slidingly connected with one side of the horizontal pushing piece, the other side of the horizontal pushing piece is fixedly connected with one side of the sealing plug, the pressurizing barrel is fixedly connected with the upper part of the first lifting telescopic frame, the output end of the pressurizing barrel is in communication with the horizontal pushing piece, the horizontal pushing piece is in communication with the sealing plug, the bottom of the second lifting telescopic frame is fixedly connected with one side of the rack, and the stop block is fixedly connected with one side of the telescopic end of the second lifting telescopic frame.

[0018] In use, the ball of the full-welded ball valve is pre-assembled in the valve body, the two sides of the valve body are sealed by welding the valve cover, and the sealing ring on one side of the valve cover is attached to the surface of the ball to form a whole sealing structure of the ball valve. During operation, the valve body is first clamped by the first clamping part, and the valve cover is clamped by the second clamping part and attached to one side of the valve body. Before welding, two preparations need to be completed: first, the telescopic end of the second lifting telescopic frame drives the stop block to move and abuts against one side of the ball to achieve limiting; second, the telescopic end of the first lifting telescopic frame drives the second lifting frame to move, and the lifting ends of the two are matched to lower the horizontal pushing piece and the sealing plug to one side of the valve cover, the horizontal pushing piece pushes the sealing plug to insert into the valve cover and establish communication, the external water pump sends water to the pressurizing barrel, and then the water is sent to the inside of the valve cover by the pressurizing barrel.

Then, the pressurizing barrel extrudes the internal water body through the pulling end to pressurize the water in the valve cover. Whether liquid leaks from the other side of the valve body is checked again. The detection result directly determines the subsequent operation. If leakage occurs, it indicates that the sealing performance is not up to standard, and relevant parts need to be adjusted or corrected before welding.

[0047] The working process of the welding device for producing a full-welded ball valve according to a specific embodiment of the present application is described below with reference to the accompanying drawings.

[0048] First, the output end of the second motor 217 in the first clamping part 210 drives the rotation of the first lead screw 214, the first lead screw 214 drives the movement of the sliding block 215, the sliding block 215 drives the movement of the clamping rod 216, thereby clamping different valve bodies. Similarly, the output end of the second motor 217 in the second clamping part 220 drives the rotation of the first lead screw 214, the first lead screw 214 drives the movement of the sliding block 215, the sliding block 215 drives the movement of the clamping rod 216, thereby clamping different valve covers, achieving separate clamping of the valve body and the valve cover.

[0049] Then, the output end of the third motor 231 drives the rotation of the disc 232, the disc 232 drives the rotation of the second clamping part 220, the clamping end of the second clamping part 220 clamps the valve cover and rotates it towards the valve body side.

When welding begins, the first clamping part 210 and the second clamping part 220 rotate the workpiece synchronously under the drive of their respective first motors 212, so that the welding machine 340 can perform circumferential welding.

[0051] Subsequently, during the welding process, the striking component 350 pushes the connecting frame 352 to rise and fall through the output end of the third telescopic component 351, adjusts the position of the striking elastic head 357, and drives the rotating disk 354 through the output end of the sixth motor 353, which in turn drives the striking elastic head 357 to strike the weld seam at high frequency through the connecting rod 355 and the reciprocating rod 356, thereby removing the welding slag in real time.

[0052] Following this, the grinding component 360 adjusts the angle of the support rod 362 through the fourth telescopic component 361, and the output end of the seventh motor 363 drives the grinding wheel 364 to rotate, synchronously grinding the welding area.

[0064] The all-welded ball valve is assembled by welding, and the sealing performance is usually detected after welding. Due to the integrated welding structure, if the sealing performance is poor after welding, subsequent disassembly and maintenance will face great difficulty.

[0065] According to the present application, as shown in the drawings, Figures 8-10As shown, it also includes a sealing detection assembly 400, which includes a first lifting telescopic frame 410, a second lifting frame 420, a horizontal pusher 430, a sealing plug 440, a pressure tank 450, a second lifting telescopic frame 460, and a stop block 470. The bottom of the first lifting telescopic frame 410 is fixedly connected to the sliding end of the first linear slide rail 240, the telescopic end of the first lifting telescopic frame 410 is fixedly connected to the upper part of the second lifting frame 420, the lifting end of the second lifting frame 420 is slidably connected to one side of the horizontal pusher 430, the other side of the horizontal pusher 430 is fixedly connected to one side of the sealing plug 440, the pressure tank 450 is fixedly connected to the upper part of the first lifting telescopic frame 410, the output end of the pressure tank 450 is connected to the horizontal pusher 430, the horizontal pusher 430 is connected to the sealing plug 440, the bottom of the second lifting telescopic frame 460 is fixedly connected to one side of the frame 100, and the stop block 470 is fixedly connected to one side of the telescopic end of the second lifting telescopic frame 460.

[0066] Before the welding operation begins, the telescopic end of the second lifting telescopic frame 460 first moves the stop block 470 to press against the ball pre-placed in the valve body to achieve a limit position. At the same time, the telescopic end of the first lifting telescopic frame 410 moves the second lifting frame 420. The two work together to lower and position the horizontal pusher 430 and the sealing plug 440 to one side of the valve cover. Then, the output end of the eighth telescopic member 431 in the horizontal pusher 430 pushes the pusher 432, so that the sealing plug 440 is inserted into the valve cover and establishes a sealed connection with it. The external water pump delivers water to the outer tank 451 through the pipeline. The outer tank 451 then delivers water through the pipeline via the pusher 432 and the sealing plug. The head 440 is injected into the valve cover for the first static pressure observation to check for water leakage on the other side of the valve body. Then, the output end of the ninth telescopic component 453 drives the piston 452 to move. At this time, the piston 452 slides inside the outer barrel 451, squeezing the water in the outer barrel 451 and pressurizing the water inside the valve cover for a second pressure test. The other side of the valve body is checked again for liquid leakage. If leakage is detected, it indicates that the seal is not qualified and needs to be adjusted. If there is no leakage, the sealing performance is confirmed to meet the standard, and subsequent welding operations can be carried out immediately. This process realizes online pre-inspection of sealing performance before welding, effectively avoiding rework caused by sealing failure after welding.
