Description

Technical Field

[0001] This utility model relates to the field of valve locking technology, and in particular to a valve locking device. Background Technology

[0002] Valves in water and gas pipelines are used to connect or disconnect the fluid within the pipeline. They are only operated when opening, closing, or maintenance is required. (See attached...) Figure 1 The valve handle shown is in the open state when it is parallel to the pipeline direction. To prevent the valve from being accidentally turned, a locking device needs to be added to the valve. Currently, chain locks or valves with locking functions are usually used to meet the requirements. However, chain locks are inconvenient to use, and valves with locking functions are expensive. Therefore, a low-cost and easy-to-use valve locking device is needed. Utility Model Content

[0026] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, this embodiment discloses a valve locking device, including a valve fixing part 1. One end of the valve fixing part 1 is fixedly provided with a pipe fixing part 2 that is clamped to a pipe 9. An adjustable tensioning part 3 is provided on the pipe fixing part 2, and a threaded locking bolt 4 is provided inside the tensioning part 3. One end of the locking bolt 4 is provided with a first locking port 5. A second locking port 6 is provided on the side wall of the pipe fixing part 2, and the second locking port 6 and the first locking port 5 are fixed by a locking device 7. The valve fixing part 1 is provided with a valve handle cavity 1-1, which is inserted into and fitted with a valve handle 8. In this embodiment, the valve fixing part 1 is a square steel tube structure, and the through cavity inside the square steel tube forms the valve handle cavity 1-1. The size of the valve handle cavity 1-1 is just enough to accommodate the valve handle 8, and after the valve handle 8 is fitted, the valve handle 8 cannot be rotated.

[0028] In use, adjust the tensioning part 3 to lock the pipe fixing part 2 onto the pipe 9, then fit the valve handle cavity 1-1 onto the valve handle 8, tighten the locking bolt 4 by threading it into the tensioning part 3, align the second locking port 6 with the first locking port 5, and lock the second locking port 6 and the first locking port 5 together using the locking device 7. After the second locking port 6 and the first locking port 5 are locked, the locking bolt 4 will no longer be rotated. With the locking bolt 4 tightened, the pipe fixing part 2 can be tightly clamped onto the pipe 9, and the pipe fixing part 2 will not move along the direction of the pipe 9 under manual operation, causing the valve handle 8 to come off.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment, the pipe fixing part 2 is an open annular structure. Both the pipe fixing part 2 and the tensioning part 3 are made of stainless steel with a certain degree of toughness. During installation, align the tensioning parts 3 on both sides of the opening of the pipe fixing part 2 with both sides of the pipe 9, and press the pipe fixing part 2 to fit the pipe fixing part 2 onto the pipe 9.

[0030] like Figures 4 to 6As shown, the tensioning part 3 includes a fixed end 3-1 and a movable end 3-2. The fixed end 3-1 and the movable end 3-2 are respectively fixedly disposed at both ends of the opening on both sides of the pipe fixing part 2. The movable end 3-2 is located on the same side as the second locking port 6. A locking screw hole 3-3 is provided in the fixed end 3-1, and the locking screw hole 3-3 is threadedly connected to the locking bolt 4. A round hole 3-4 is provided in the movable end 3-2, and the position of the round hole 3-4 corresponds to the position of the locking screw hole 3-3. The round hole 3-4 is slidably connected to the locking bolt 4. In this embodiment, a first nut 11 is welded to one end of the locking bolt 4, and the nut hole in the middle of the first nut 11 forms a first locking port 5. A second nut 10 is welded to the side wall of the pipe fixing part 2, and the nut hole in the middle of the second nut 10 forms a second locking port 6. A reinforcing end 3-5 is provided on the fixed end 3-1, and a locking screw hole 3-3 is provided in the reinforcing end 3-5. The reinforcing end 3-5 is also a nut, and the nut hole in the middle of the nut forms the locking screw hole 3-3. The function of the reinforcing end 3-1 is to make the tightening of the locking bolt 4 more secure.

[0031] After the pipe fixing part 2 is fitted onto the pipe 9 and the valve handle cavity 1-1 is fitted onto the valve handle 8, the first locking port 5 of the locking bolt 4 is located on the same side as the second locking port 6. The locking bolt 4 is inserted into the round hole 3-4 and the locking screw hole 3-3 in sequence, and the locking bolt 4 is rotated to tighten it with the locking screw hole 3-3. During this process, the pipe fixing part 2 is continuously tightened and thus fixed onto the pipe 9, and the first locking port 5 and the second locking port 6 are aligned. The locking device 7 is then used to lock it in place.

[0032] like Figures 1 to 6 As shown, the operation process of this utility model is as follows:

[0033] First, pry open the fixed end 3-1 and the movable end 3-2, align the opening of the pipe fixing part 2 with both sides of the pipe 9, and press the pipe fixing part 2 to fit onto the pipe 9. Rotate the valve handle 8 until it is parallel to the pipe 9 and tighten it so that the valve handle 8 faces the valve handle cavity 1-1. Slide the pipe fixing part 2 along the direction of the pipe 9 to fit the valve handle cavity 1-1 onto the valve handle 8. Position the first locking port 5 of the locking bolt 4 on the same side as the second locking port 6. Insert the locking bolt 4 into the round hole 3-4 and the locking screw hole 3-3 in sequence, and rotate the locking bolt 4 to tighten it with the locking screw hole 3-3. During this process, the pipe fixing part 2 continuously tightens and becomes secure to the pipe 9, ensuring that the pipe fixing part 2 locks the pipe 9 and cannot move along the direction of the pipe 9. Align the first locking port 5 with the second locking port 6 and lock the first locking port 5 and the second locking port 6 with the lock 7.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
