[0019] In order to make the above purpose, features and advantages of the utility model more obvious and easy to understand, the utility model is further explained in detail below by combining with the drawings and specific embodiments.

[0020] The existing valve structure is generally composed of support frame, valve stem, valve core, hand wheel and other key components. The support frame is a support and connection frame structure of the valve. The valve stem is fixed on the support frame and connected with the valve core. The hand wheel is fixed on the top of the valve stem and used for manual rotation to operate the valve opening and closing. When the support frame is broken, the valve cannot be normally used. The current repair method usually needs to stop production, and complex disassembly and welding operations are required, which consumes a lot of time and manpower.

[0021] To solve the problems of the prior art, the embodiment discloses a valve support frame running fracture emergency repair tool, referring to Figs. 1-3 which comprises clamping device and support device.

[0022] The clamping device comprises two arc-shaped clamping pieces 1 clamped on both sides of the valve support frame and fixed with each other. The arc-shaped clamping piece 1 is made of high-strength alloy material and has good corrosion resistance and strength, which can bear the weight and working pressure of the valve support frame. Specifically, the clamping device further comprises clamping bolts 2 and clamping nuts 3 matched with the clamping bolts 2. The arc-shaped clamping piece 1 is provided with a fixed hole through which the clamping bolt 2 passes. The two arc-shaped clamping pieces 1 are connected and fixed with each other by the clamping bolt 2 and the clamping nut 3, so as to firmly fix the two arc-shaped clamping pieces 1 on the broken valve support frame. As a preferred solution, the inner side of the arc-shaped clamping piece 1 is provided with an antiskid rubber pad, which further improves the clamping stability of the clamping device on the valve support frame.

[0023] The support device comprises a support rod 4, a fixed disc 5 and a fixed nut 6. The support rod 4 is fixed with the arc-shaped clamping piece 1 by welding or threaded connection. In the embodiment, the welding is preferred, which can better ensure that the support rod 4 will not loosen or fall off during the repair process, thereby improving the safety of the repair. The top of the support rod 4 is connected with the fixed disc 5. Specifically, the support rod 4 is a threaded rod, and the fixed disc 5 is provided with a threaded hole. The fixed disc 5 is screwed with the support rod 4. In this way, the height of the fixed disc 5 on the support rod 4 can be adjusted according to the actual height of the support frame. Of course, the support rod 4 and the fixed disc 5 can also be fixed by welding, and the threaded connection is more convenient for workers to adjust the height for fixing. In addition, the support rod 4 is preferably provided with multiple support rods. In the embodiment, the support rod 4 is provided with two support rods. The fixed disc 5 is disc-shaped. The support rods 4 are respectively arranged at the symmetrical positions of the diameter line passing through the center of the fixed disc 5, so as to improve the support stability. The fixed disc 5 is provided with a center hole 51 through which the valve stem passes. The top of the valve stem is screwed with the fixed nut 6 after passing through the center hole 51 of the fixed disc 5. The fixed nut 6 locks and fixes the valve stem and the fixed disc 5.

[0024] When the valve support frame is broken, the operator first removes the hand wheel of the valve, then installs the arc-shaped clamping pieces 1 around the original valve support frame, clamps the broken support frame by clamping the two arc-shaped clamping pieces 1 through the fixing holes of the clamping bolts 2 and adjusting the clamping nuts 3. Then, according to the broken position and the height size of the support frame, the relative position of the support rods 4 and the fixing disc 5 is adjusted, the two support rods 4 are consistent in height so that the fixing disc 5 is installed horizontally, the valve rod passes through the center hole 51 of the fixing disc 5, then the support rods 4 and the arc-shaped clamping pieces 1 are spot-welded together to ensure the stability of the entire repair tool, finally, the fixing nut 6 is screwed into the valve rod and fixed on the fixing disc 5. In this way, the support device replaces the original support frame function, during use, the operator can adjust the position of the repair tool at any time according to the actual situation to ensure that the valve can work normally. When the production task is completed, the broken valve support frame can be thoroughly repaired or replaced, and then the emergency repair tool is removed for next use.

[0025] The technical solutions provided by the utility model are described in detail above, and the principles and implementation modes of the utility model are described by applying specific examples in this paper, and the above example is only used to help understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the utility model, the specific implementation mode and application range will be changed, and according to the above, the content of the specification should not be understood as the limitation of the utility model.
