Description

Technical Field

[0002] Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, non-return, pressure stabilization, flow diversion and overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water vapor, various corrosive media, mud, oil, liquid metal and radioactive media. The valve body is an important part of the valve, which is mainly forged from valve steel.

[0024] The implementation principle of the valve body pipe mouth and flange welding device of this embodiment is as follows: when the valve body pipe mouth and the flange need to be welded, the operator places the valve body between the two gear rings 306, and at this time, the electric telescopic rod 1 310 is started to drive the clamping plate 311 to move, and because there are multiple clamping plates 311, they can move at the same time and contact the surface of the valve body, so that the valve body can be clamped and fixed, and at this time, the double-headed motor 302 is started to drive the rotating rod 1 303 to rotate, and the rotating rod 1 303 rotates to drive the gear 1 306 to rotate. 05 rotates, the rotation of the gear 1 305 can drive the two gear rings 306 to rotate, and the rotation of the gear ring 306 can drive the rotating rod 307 to slide on the inner side of the fixed plate 1 308, so as to increase the stability of the gear ring 306 when rotating, and the rotation of the gear ring 306 can drive the valve body clamped and fixed between the two gear rings 306 to rotate, and the flange can be clamped and fixed to the valve body pipe mouth by the clamping mechanism 4, and the rotation of the valve body can drive the flange to rotate together, so as to effectively improve the working efficiency of the welding equipment and better perform the welding work; When it is necessary to weld the valve body pipe mouth and the flange, the operator places the valve body between the two gear rings 306, and the valve body can be clamped and rotated by starting the rotating mechanism 3. At this time, the flange is placed on the placement plate 408 and the limit rod 409. At this time, the threaded plate 411 can be driven to move by rotating the threaded rod 410, and the extrusion block 412 is driven to move outward by the movement of the threaded plate 411. As the extrusion block 412 continues to move, it can contact the inner side of the flange and can clamp and fix the flange. As the threaded plate 411 moves, the limit plate 413 can be driven to move. When the flange is clamped and fixed, the moving plate 403 is driven to slide on the guide rod 405 by starting the electric telescopic rod 2 402, thereby increasing the stability of the moving plate 403 when moving. As the moving plate 403 slides, the bearing plate 1 404 can be driven to move The movement of the bearing plate 404 can indirectly drive the placement plate 408 and the limit rod 409 to move, and the movement of the placement plate 408 and the limit rod 409 can drive the flange to move. As the placement plate 408 and the limit rod 409 continue to move, the flange can be brought into contact with the valve body pipe mouth, and at this time, as the movement continues, one side of the limit plate 413 can contact the inner side of the valve body pipe mouth, and at this time, the movement of the limit plate 413 can be fixed on the inner side of the valve body pipe mouth, so that the flange and the valve body pipe mouth can be clamped and fixed, and when the valve body rotates, the flange can be rotated through the clamping mechanism 4, and the placement plate 408 and the limit rod 409 are driven to rotate by the rotation of the flange, and the rotation rod 2 407 is driven to rotate on the side of the bearing plate 404 by the rotation of the placement plate 408, so that the flange can be rotated with the rotation of the valve body, so as to further improve the working efficiency of the welding equipment; When it is necessary to weld the valve body pipe mouth and the flange, the operator places the valve body between the two gear rings 306, and the valve body can be clamped and fixed and rotated by starting the rotating mechanism 3, and the flange can be clamped and fixed by starting the clamping mechanism 4, and as the flange continues to move, it can contact the valve body pipe mouth and be clamped and fixed, so that the flange can be driven to rotate at the same time when the valve body rotates, and at this time, the connecting plate 2 504 is driven to move by starting the hydraulic cylinder 503, and the welding gun 505 can be driven to move by the movement of the connecting plate 2 504, and at this time, the grinding disc 512 can be When the welding is completed, the welding gun 505 is reset by starting the hydraulic cylinder 503, and the movement of the connecting plate 2 504 can drive the installation plate 3 506 to move, and the movement of the installation plate 3 506 drives the moving rod 507 to move, and the movement of the moving rod 507 drives the sliding plate 508 to move, and the movement of the sliding plate 508 drives the moving rod 507 to move. The adjusting plate 513 slides on the inner wall of the adjusting box 514, thereby increasing the stability of the sliding plate 508 when it moves. As the sliding plate 508 moves, the mounting plate 4 509 can be driven to move, and the rotating rod 3 510 can be driven to move through the movement of the mounting plate 4 509. The movement of the rotating rod 3 510 can drive the gear 2 511 to move, and then the gear 2 511 can be made to contact with the gear 1 305. At this time, the double-headed motor 302 is in a closed state, and the gear 1 305 is in a stationary state. When the gear 2 511 moves to contact and mesh with the gear 1 305, the double-headed motor 302 works to drive the gear 1 305 rotates, and the rotation of gear one 305 drives gear two 511 to rotate, and the rotation of gear two 511 drives the rotating rod three 510 to rotate, and the rotation of the rotating rod three 510 drives the grinding disc 512 to rotate. Since the radius of the ring gear 306 is greater than that of gear two 511, the rotation speeds of the valve body and the grinding disc 512 are different, so that the grinding disc 512 can grind the welding part between the valve body pipe mouth and the flange, and can cooperate with the valve body pipe mouth and the flange to rotate for grinding, thereby improving the grinding efficiency, and improving the welding effect of the welding equipment, so that the welding work can be better performed.
