Description

Technical Field

[0001] This utility model relates to the field of valve opening and closing technology, and in particular to a handwheel valve opening and closing auxiliary tool. Background Technology

[0002] In daily production processes in industries such as petrochemicals, valve operation is extremely common. The smooth opening and closing of valves directly affects the stable and efficient operation of the entire production process. When valves have not been used for a long time, are corroded by the media inside the pipeline, or are affected by the external environment, their internal structure may develop rust or jamming, making them difficult to start. Workers often need to use force-applying devices to open these types of valves.

[0003] Currently, the handles and handwheels of common handwheel valves are mostly made of metal. During long-term use, their strength gradually decreases due to frequent external forces; furthermore, they are susceptible to corrosion from moisture and chemicals. When workers use force-applying devices to open the valve, improper force application—such as applying excessive torque to a single point or deviating from the direction of force—can easily cause the already potentially hazardous handle or handwheel to break. A broken handle or handwheel not only prevents the valve from opening properly, affecting production progress, but can also lead to serious safety accidents, causing economic losses and personal injury. Utility Model Content

[0004] This invention addresses the problem of uneven force applied during the opening and closing of handwheel valves of different sizes, which can easily damage the valves. It provides an auxiliary tool for opening and closing handwheel valves.

[0005] This utility model is achieved by adopting the following technical solution.

[0006] A handwheel valve opening and closing auxiliary tool includes a drive wrench and a pawl holding base; the pawl holding base includes a hexagonal nut located in the center, three base crossbars are evenly connected to the outer wall of the hexagonal nut, and a number of fixing balls are symmetrically arranged on the upper and lower surfaces of the base crossbars; an adjusting pawl is sleeved on the base crossbars, and the lower end of the adjusting pawl engages with the handwheel valve.

[0007] Furthermore, the drive-operated wrench includes a wrench end and a handle end, with the handle end connected to the tail end of the wrench end.

[0008] Furthermore, the dimensions of the wrench end correspond to those of the hexagonal nut.

[0009] Furthermore, the upper and lower surfaces of the base crossbar are each provided with 8 fixing balls, and the positions of the 8 fixing balls correspond to the valve handwheels of 3 to 10 inches respectively.

[0010] Furthermore, the adjusting claw includes a connecting ring and a claw, with the lower end of the connecting ring connected to the open claw via a connecting rod.

[0011] Furthermore, the connecting ring has bead grooves on its upper and lower sides that match the fixing beads.

[0012] This application has the following beneficial effects.

[0013] This utility model tool has the advantages of simple structure, low cost and strong versatility. It can be adapted to valves of different specifications and effectively solves the problem of valve damage caused by traditional force application methods. It is highly practical.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-2 As shown, a handwheel valve opening and closing auxiliary tool includes a drive wrench 1 and a chuck holding base.

[0018] The drive-operated wrench 1 includes a wrench end 11 and a handle end 12. The wrench end 11 can be connected to the hexagonal nut 2 of the chuck-holding base to rotate the nut. The handle end 12 is connected to the tail end of the wrench end 11. The handle end 12 is a hollow rod, and its inner diameter is 3-5mm larger than the outer diameter of the base crossbar 3. It can be fitted onto the tail end of the base crossbar 3 to apply torque. This torque is greater than that of the valve handwheel, which can reduce the opening force. In actual operation, it can be selectively connected to a certain crossbar of the chuck-holding base according to the actual working conditions and the angle of force to apply torque and realize the valve opening and closing function.

[0019] The claw-holding base includes a hexagonal nut 2, an adjusting claw 4, a base crossbar 3, and fixing balls 5. The hexagonal nut 2 is an M50 hexagonal nut, and three base crossbars 3 are evenly welded to the outer wall of the hexagonal nut 2. The main body of the claw-holding base is a three-legged crossbar of equal length, which can provide a stable support foundation. Several fixing balls 5 are symmetrically arranged on the upper and lower surfaces of each base crossbar 3. Specifically, eight equally sized fixing balls 5 are arranged on the upper and lower surfaces of the base crossbar 3. The positions of the eight fixing balls 5 correspond to the valve handwheel sizes of 3-inch, 4-inch, 5-inch, 6-inch, 7-inch, 8-inch, 9-inch, and 10-inch, respectively. The adjusting claw 4 can be used to fix valve handwheels of 3-10 inches.

[0020] In this application, the upper end of the adjusting claw 4 forms a connecting ring 41, which is designed to be square. The connecting ring 41 is fitted and connected to the base crossbar 3. The upper and lower parts of the connecting ring 41 are respectively provided with ball grooves. The lower end of the adjusting claw 4 forms an open claw 42 with a lower opening of 3-6cm, which is used to fix the valve handwheel.

[0021] When opening and closing the handwheel valve, according to the specific valve size, fix the adjusting claw 4 to the position of the fixed ball 5 corresponding to the base crossbar 3, then connect the claw 42 of the adjusting claw 4 to the valve handwheel, and finally, according to the on-site working conditions, use the drive wrench 1 connected to the hexagonal nut 2 of the base to rotate to open and close the valve.

[0022] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
