Description

Technical Field

[0001] The utility model relates to the technical field of valve maintenance, in particular to a device that is convenient for maintaining a leaf valve. Background Art

[0002] The leaf valve is a commonly used industrial valve. Its structure is similar to a door plate, usually called a leaf or blade, which can move inside the pipe to control the flow of fluid. The leaf valve is usually composed of a valve body, a leaf, a stem, a seal and an operating device. The leaf valve requires regular maintenance to ensure its normal operation and to ensure the safe, reliable and efficient operation of the system.

[0003] After searching, the Chinese patent with announcement number: CN213738424U discloses a valve maintenance equipment that is easy to operate, including a shell, and the interior of the shell is connected with a lifting mechanism that allows maintenance personnel to conveniently observe the valve condition in all directions. The utility model solves the problem that maintenance personnel cannot observe the valve in all directions when repairing the valve by adding a lifting mechanism, and realizes that after the maintenance personnel disassemble the valve, the valve is placed on the lifting mechanism, and the height can be adjusted to observe the valve in all directions. At the same time, a collection box is added, and other small tools required for repairing the valve and small parts removed from the valve can be placed in the collection box, thereby avoiding the loss of parts and tools, and also avoiding the problem of the valve accidentally falling and being damaged and injuring the maintenance personnel during the maintenance process, reducing the maintenance work time extended due to observing the valve, and improving the efficiency of the maintenance work.

[0004] The above specific implementation method mentions that "after the valve is disassembled, the lifting mechanism 2 is used to facilitate observation of the valve. When using the lifting mechanism 2, hold the handle 13 and rotate it counterclockwise to drive the first metal shaft 9 to rotate through the ball bearing 5, and at the same time drive the first gear 10 to rotate counterclockwise. The first gear 10 drives the second gear 12 to rotate counterclockwise, drives the rack 8 to move upward, and drives the support rod 11 to move upward. After the maintenance or observation is completed, hold the handle 13 and rotate it clockwise to drive the rack 8 and the support rod 11 to move downward. When the handle 13 is rotated, the first metal shaft 9 drives the turntable 14 and the wedge block 15 to move. The wedge block 15 contacts the wedge-shaped card strip 18 to push the wedge-shaped card strip 18 into the groove 17. When the spring 20 reaches a certain position, the wedge-shaped card strip 18 pops out and is stuck between the wedge-shaped blocks 15, so that the handle 13 will not move in the opposite direction. After use, the latch 23 is pressed down, and the top of the latch 23 contacts the wedge-shaped hole 19 to retract the wedge block 15, and then the handle 13 is turned to move, and the latch 23 is lowered and contacts the stopper 24, so that the latch 23 will not fall, so that when the required position is reached, the first gear 10 can be stuck and will not rotate. However, in the above document, the support rod cannot support different pipelines, resulting in a small application range of the device, and the support rod cannot fix the pipeline, resulting in the pipeline shaking during the disassembly process, which hinders the user from disassembling. In view of the above problems, a device for facilitating the maintenance of leaf valves is proposed to solve the above problems. Utility Model Content

Compared with the above documents, the above is more compact, which is convenient for users to fix and support the external pipe 2, and can fix and support external pipes 2 of different sizes. The front side of the battery box 4 is fixedly connected with a transmission line 13, and the front end of the transmission line 13 is fixedly connected with an electric handle 14. The battery box 4 transmits power to the electric handle 14 through the transmission line 13.

[0025] refer to Figure 1 , Figure 2A placement groove 24 is provided on the front side of the auxiliary box 3, and the placement groove 24 is convenient for storing the electric handle 14. The limiting assembly includes a threaded rod 11 and a threaded turntable 12. The rear end of the threaded rod 11 is rotatably connected to the middle of the positioning block 10, and the inner wall of the threaded turntable 12 is rotatably connected to the outside of the threaded rod 11. The outer thread of the threaded rod 11 is connected to the middle of the front connecting block 9. Rotating the threaded turntable 12 drives the threaded rod 11 to rotate, so that the two rotating frames 6 are folded, so that the top of the rotating frame 6 drives the clamping ring 8 to wrap the outside of the external tube 2 for clamping and fixing.

[0026] refer to Figure 3 The top of the electric handle 14 is fixedly connected to a support cover 15, the electric handle 14 fixes the support cover 15, the front side of the inner part of the support cover 15 is rotatably connected to a rotating rod 16, the outer part of the rotating rod 16 is fixedly connected to a worm 17, the support cover 15 supports the rotating rod 16 to drive the worm 17 to rotate, the bottom end of the rotating rod 16 is fixedly connected to a rotating cover 18, the top of the rotating cover 18 is rotatably connected to the outer bottom end of the support cover 15, rotating the rotating cover 18 drives the rotating rod 16 to rotate, the rear teeth of the semi-arc worm wheel 20 are meshed with the outer teeth of the worm 17, the worm 17 drives the semi-arc worm wheel 20 to rotate, and the left and right sides of the inner part of the support cover 15 are fixedly connected to positioning rods 19.

The middle part of the outside of the disassembly head 21 is slidably connected to the inner wall of the notch 22, and the bottom end of the soft strip 23 is fixedly connected to the middle of the outside of the disassembly head 21. This design allows the soft strip 23 to fold as the disassembly head 21 rotates, thereby preventing dust from entering the support cover 15.

[0028] Working principle: When the user needs to disassemble the valve body 1, the user can first align the rotating frame 6 and the clamping ring 8 on one side with the outside of the external tube 2, and then rotate the threaded turntable 12 to drive the threaded rod 11 to rotate, so that the two rotating frames 6 can be folded, so that the top of the rotating frame 6 drives the clamping ring 8 to wrap the outside of the external tube 2 for clamping and fixing. At this time, the pipeline pressure of the external tube 2 can be reduced to prevent the external tube 2 from being damaged due to excessive pressure after the valve body 1 is completely disassembled.

[0029] When the user needs to remove the bolts on the valve body 1, the energy can be transmitted through the power box 4 via the connection of the transmission line 13 to start the disassembly head 21 to automatically disassemble the bolts. At the beginning of disassembly, the user can rotate the rotary cover 18 to drive the worm 17 to rotate, and the rotation of the worm 17 drives the semi-arc worm gear 20 to rotate, so that the disassembly head 21 can be rotated up and down, so that the angle of the disassembly head 21 is more suitable for user use.
