Description

Technical Field

[0001] This utility model relates to the field of pipeline valve technology, specifically a convenient tool for opening and closing valves in trenches or pipeline wells. Background Technology

[0002] Industrial pipeline trenches or wells often contain unidentified gases or are filled with water due to sudden rainfall. During maintenance, operators are often unable to safely enter the well to open or close valves, posing significant safety hazards during emergency repairs. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a convenient valve switching tool for trenches or pipe wells, including a fixed support rod, an adjusting support rod, an adjusting hole, a positioning plate, a fixing tooth, a handwheel switch, a movable branch pipe, a perforated positioning pin, and an R-shaped cotter pin; the fixed support rod is a U-shaped rod, with an adjusting support rod welded and fixed to its upper center and a positioning plate welded and fixed to its bottom surface; the adjusting support rod has several adjusting holes at equal intervals; the fixing tooth is vertically welded and fixed to the left and right sides of the lower side of the positioning plate; the handwheel switch is a prototype, with a movable branch pipe welded and fixed to its lower surface center; the movable branch pipe has a positioning hole on its lower side, which fits onto the adjusting support rod; the perforated positioning pin passes through the adjusting hole and the positioning hole and then engages with the R-shaped cotter pin for fixation.

[0004] As a preferred embodiment of this utility model, the positioning disk has a circular hole in the center.

[0005] The advantages of this invention are: It eliminates the need for personnel to enter the trench for operation, ensuring operator safety and smooth valve opening and closing. The adjustable connecting rod accommodates valves at different depths. The detachable design facilitates tool carrying; simply connect the connecting rods for immediate use.

[0011] Example 1

[0012] like Figures 1 to 3 As shown, this utility model discloses a convenient valve switching tool for trenches or pipe wells, including a fixed support rod 1, an adjusting support rod 2, an adjusting hole 3, a positioning plate 4, a fixing tooth 5, a handwheel switch 6, a movable branch pipe 7, a perforated positioning pin 8, and an R-type cotter pin 9. The fixed support rod 1 is a U-shaped rod, with the adjusting support rod 2 welded and fixed to its upper center, and the positioning plate 4 welded and fixed to its bottom surface. The adjusting support rod 2 has several adjusting holes 3 at equal intervals. The fixing tooth 5 is vertically welded and fixed to the left and right sides of the lower side of the positioning plate 4. The handwheel switch 6 is a prototype, with the movable branch pipe 7 welded and fixed to its lower surface center. The movable branch pipe 7 has a positioning hole on its lower side, which fits onto the adjusting support rod 2. The perforated positioning pin 8 passes through the adjusting hole 3 and the positioning hole, and then engages with the R-type cotter pin 9 for fixation. The positioning plate 4 has a round hole in its center, allowing the threaded shaft of the valve switch to pass through, ensuring smooth lifting and lowering. The fixing tooth 5 engages with the original handwheel switch of the valve, ensuring smooth lifting and lowering.

[0013] The working principle of this utility model is as follows: In use, the height of the movable branch pipe 7 can be selected according to the depth of the trench. A perforated positioning pin 8 passes through the adjusting hole 3 and the positioning hole, and is then fixed in place by an R-type cotter pin 9. Next, the fixing teeth 5 are inserted into the handwheel of the valve, and the threaded shaft of the valve switch passes through the round hole of the positioning plate 4. Rotating the handwheel switch 6 then drives the valve to turn, thus opening or closing the valve. The entire unit is detachable, making it easy to carry and install.

[0014] Components not described in detail in this article are existing technologies.

[0015] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
