Description

Technical Field

[0001] This utility model relates to the field of opening and closing tools, specifically to gas valve control tools. Background Technology

[0002] When gas valves are installed in buried gas pipeline valve wells, workers need to go down into the well to operate the valves. Due to the limited operating space, it is difficult to operate the valves. Therefore, it is necessary to use opening and closing tools to assist in operating the gas valves. However, existing opening and closing tools still have certain defects in use, such as: Because valve stems vary in specifications and dimensions, workers need to carry various opening and closing tools to operate different valve stems, which is quite troublesome. Furthermore, many gas pipelines are laid in the field, and when a leak occurs, workers can only go to the gas valve well to close the pipeline valve manually. In most cases, it is not possible to detect the valve torque and operate it remotely. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a gas valve control tool, including a housing 1 for installing parts, a geared motor 2 for providing power is connected through one side of the inner wall of the housing 1, the output end of the geared motor 2 is connected through the inner wall of the housing 1 to a torque sensor 3 for detecting torque via a coupling, a baffle 4 for supporting the torque sensor 3 is connected to the outside of the torque sensor 3, the baffle 4 is connected to the bottom of the housing 1, a telescopic rod a5 for driving the rotation of a sleeve mechanism 6 is connected below the torque sensor 3 via a coupling, a sleeve mechanism 6 for rotating the gas valve is provided below the telescopic rod a5, and a limiting mechanism 7 for installation with the well wall is provided on the outside of the baffle 4; This gas valve electric opening and closing tool has a lithium battery and controller installed inside the housing 1 to control the rotation of the geared motor 2. The torque sensor 3 detects the torque of the geared motor 2 and displays it on the screen on the housing 1. The geared motor 2 adopts a worm gear reducer and is capable of self-locking.

[0017] exist Figure 3 In the middle, the socketing mechanism 6 includes a socket 601 for installing the sleeve 603 connected to the lower part of the telescopic rod a5. A U-shaped plate 602 for suspending the sleeve 603 is slidably connected inside the socket 601. The bottom of the U-shaped plate 602 is fixedly connected to the sleeve 603 for rotating the gas valve. The socket 601 has a storage slot 604 for installing parts, and a gear 605 for driving the toothed plate 607 to move is rotatably inserted through the inner wall of the storage slot 604.

[0018] This electric gas valve opening and closing tool involves inserting the sleeve 603 onto the gas valve, rotating the outer shell 1 to rotate the telescopic rod a5 and the sleeve 603, thus opening or closing the gas valve, and pulling down the sleeve 603 to pull the U-shaped plate 602 out of the socket 601.

[0019] exist Figure 3 In the middle, the inner sidewall of the U-shaped plate 602 is provided with a slot 606 for engaging the toothed plate 607. The gear 605 is meshed with toothed plates 607 above and below for limiting the U-shaped plate 602. The toothed plates 607 are engaged in the slot 606.

[0020] The electric gas valve opening and closing tool uses a rotating gear 605 to drive the toothed plate 607 out of the slot 606, releasing the restriction on the U-shaped plate 602, thereby pulling the U-shaped plate 602 out of the socket 601.

[0021] exist Figure 3 and Figure 4 In the middle, a tension spring 608 is connected to one side of the inner wall of the storage slot 604 for resetting the toothed plate 607. The tension spring 608 is connected to one side of the toothed plate 607.

[0022] When the rotating gear 605 drives the toothed plate 607 out of the slot 606, the tension spring 608 is stretched. After the gear 605 is released, the tension spring 608 pulls the toothed plate 607 to reset, and the toothed plate 607 drives the gear 605 to reset.

[0023] exist Figure 1 , Figure 2 and Figure 5 In the middle, the limiting mechanism 7 includes a telescopic rod b701 for supporting the well wall that abuts against the outside of the baffle 4. The bottom of the telescopic rod b701 is connected to a right-angle self-locking hinge 702 for limiting the telescopic rod b701. The right-angle self-locking hinge 702 is connected to the outside of the baffle 4. Artificial strong magnets 703 for limiting the telescopic rod b701 are connected to both the outside of the baffle 4 and the bottom of the telescopic rod b701.

[0024] When the telescopic rod b701 of this gas valve electric opening and closing tool is rotated to the vertical position, two sets of artificial strong magnets 703 attract each other to prevent the telescopic rod b701 from rotating. When the telescopic rod b701 is rotated to the horizontal position, the right-angle self-locking hinge 702 limits the position of the telescopic rod b701 to prevent the telescopic rod b701 from resetting.

[0025] exist Figure 5 In the middle, a square groove 704 is provided on one side of the telescopic rod b701 for sliding the block 705. The block 705 for moving the pad 706 is slidably connected in the square groove 704. The pad 706 for abutting against the well wall is fixedly connected to one side of the block 705.

[0026] The electric gas valve opening and closing tool adjusts the length of the telescopic rod b701 to bring the pad 706 close to the well wall, then slides the block 705 in the square groove 704 to push the pad 706 to abut against the well wall, and then uses an expansion bolt to fix the pad 706 to the well wall.

[0027] exist Figure 5 In the middle, one side of the square 705 is threadedly connected to a threaded rod 707 for driving the square 705 to slide through a threaded groove. The threaded rod 707 is rotatably connected to the inner wall of the square groove 704.

[0028] The electric opening and closing tool for the gas valve uses a rotating threaded rod 707 to push a block 705 to slide within a square groove 704. A limit groove is provided on the inner wall of the square groove 704, and a limit rod is slidably connected within the limit groove. The limit rod is installed on the outside of the block 705 to prevent the block 705 from sliding out of the square groove 704.

[0029] exist Figure 5 In the middle, the outer side of the threaded rod 707 is connected to a drive worm gear 708 for driving the threaded rod 707 to rotate, and the outer side of the drive worm gear 708 is meshed with a drive worm 709 for driving the drive worm gear 708 to rotate. The drive worm 709 passes through and is rotatably connected to the inner wall of the square groove 704.

[0030] This electric gas valve opening and closing tool is used to drive the worm gear 709 to rotate the drive worm wheel 708, which is self-locking. Rotating the drive worm gear 709 drives the drive worm wheel 708 to rotate, and the drive worm wheel 708 drives the threaded rod 707 to rotate.

[0031] In summary: When using this gas valve control tool, first, open the gas well and observe the model of the gas valve. Rotate gear 605 to remove and replace sleeve 603. Adjust the length of telescopic rod a5 according to the depth of the gas valve. Hold the outer casing 1 and insert sleeve 603 onto the gas valve and rotate it. Torque sensor 3 detects the reaction force of telescopic rod a5 and displays the torque on the screen of outer casing 1 for recording. Then, rotate the gas valve to reset it. Start the reduction motor 2 to drive torque sensor 3 and sleeve 603 to rotate. Rotate the gas valve until the recorded torque is reached. Record the number of rotations of reduction motor 2 for learning. Then, rotate telescopic rod b701 to horizontal position and adjust the length of telescopic rod b701 so that pad 706 is close to the well wall. Then, rotate drive worm 709 to abut pad 706 against the well wall and fix it with expansion bolts. Use SCADA system to remotely control the rotation of reduction motor 2 and remotely manage the gas valve. Content not described in detail in this instruction belongs to the prior art known to those skilled in the art.
