Description

Technical Field

[0001] This utility model belongs to the field of gas valve installation technology, and in particular relates to a positioning device for gas valve installation. Background Technology

[0002] The main function of a gas valve is to cut off and connect the gas in the pipeline, thereby controlling the flow of gas. Proper operation of a gas valve can quickly shut off the gas supply in emergencies such as gas leaks, preventing further gas leakage and avoiding potential fires or explosions. Gas valves need to be replaced regularly to prevent gas leaks caused by aging components.

[0003] The problem with the above technology is that when replacing and installing gas valves, the installation location of gas pipelines is uncertain. If the gas pipeline is installed in a high place, the traditional installation method involves manual installation, which requires holding the gas valve up continuously. This is unstable, leading to troublesome installation and poor installation quality. Furthermore, it is not convenient to detect gas leaks in a timely manner after installation. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a positioning device for gas valve installation that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a positioning device for installing a gas valve includes a bracket and a movable frame. One side of the movable frame is slidably connected to the bracket via a slider and a sliding groove. A fixing mechanism is provided on the inner side of the movable frame, and a lifting mechanism is provided on the left side of the movable frame. A support plate is fixedly installed on the inner side of the movable frame, and a gas valve is placed on the top of the support plate.

[0006] To secure the gas valve, preferably, the securing mechanism includes a first motor fixedly mounted on one side of the movable frame. The output end of the first motor on the left side passes through the right side of the movable frame and is fixedly connected to a first threaded rod. One end of the first threaded rod is rotatably connected to the inner side of the movable frame via a bearing. A clamping plate is slidably connected to the inner side of the movable frame via a slider and a groove. The inner wall of the clamping plate is threadedly connected to the surface of the first threaded rod. After the first motor is started, it drives the first threaded rod to rotate. Since the clamping plate is slidably connected to the groove of the movable frame via the slider, and the inner wall of the clamping plate is threadedly engaged with the threaded rod, the rotation of the threaded rod is converted into linear movement of the clamping plate. By controlling the forward and reverse rotation of the first motor, the distance between the two clamping plates can be adjusted, thereby clamping or releasing the gas valve.

[0007] To align the gas valve with the pipe opening, the lifting mechanism preferably includes a second motor. The bottom of the second motor is fixedly connected to a bracket, and a second threaded rod is fixedly connected to the output end of the top of the second motor. A fixing block is fixedly connected to the left side of the movable frame. One end of the second threaded rod passes through the fixing block and extends upward. The inner wall of the fixing block is threadedly connected to the surface of the second threaded rod. The second motor drives the second threaded rod to rotate, and the thread on the inner wall of the fixing block engages with the threaded rod, causing the movable frame to move up and down along the axis of the threaded rod. By controlling the speed and direction of the second motor, the vertical height of the valve can be precisely adjusted through the movable frame until it is aligned with the pipe interface, reducing the physical exertion of the installers.

[0008] To further secure the gas valve, preferably, a fixing plate is fixedly connected to the top right side of the movable frame. A bolt is threaded onto the inner wall of the fixing plate, and the bottom of the bolt passes through the fixing plate and is rotatably connected to a washer via a bearing. The bottom of the washer contacts the gas valve. When the bolt is rotated, the bolt moves downward along the threaded hole of the fixing plate, and the bearing drives the washer to press against the top of the gas valve, thus forming a double clamping mechanism with the fixing mechanism, consisting of upper and lower clamping and side clamping.

[0009] To detect gas leaks in a timely manner, preferably, a compression block is fixedly connected to the top of the left clamping plate. After the gas valve is installed, the valve can be opened to supply gas. At this time, the first motor is started to make the clamping plate move away from the gas valve. When the left clamping plate moves, it will squeeze the water storage box through the compression block.

[0010] To detect gas leaks promptly, preferably, a water storage box is fixedly connected to the top left side of the movable frame, and a water outlet pipe is fixedly connected to the right side of the water storage box. A first one-way valve is installed on the surface of the water outlet pipe, which can only discharge water. A water inlet pipe is fixedly connected to the left side of the water storage box, and a second one-way valve is installed on the surface of the water inlet pipe, which can only allow water to enter. The rubber water storage box is deformed by the extrusion block, causing the soapy water stored inside to be sprayed out through the water outlet pipe and the first one-way valve (water only). The soapy water is sprayed onto the interface between the gas valve and the gas pipeline, so that any gas leaks can be detected immediately.

[0011] To improve the practicality of the water storage box, it is preferably made of rubber. A rubber water storage box can automatically return to its original shape after being squeezed, which is simple and practical.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model incorporates a fixing mechanism, a lifting mechanism, and a water storage box. The fixing mechanism, driven by a first motor and a first threaded rod, causes the clamping plate to slide, thus clamping the gas valve. The clamping distance is adaptively adjustable, compatible with multiple valve sizes, and provides stable clamping while improving efficiency. The lifting mechanism, driven by a second motor and a second threaded rod, enables precise lifting and lowering of the movable frame, reducing labor intensity. By storing water and promptly detecting gas leaks, this invention solves the problem of traditional manual installation methods for gas valves at higher locations. These methods require holding the gas valve continuously, which is unstable, cumbersome, and prone to poor installation quality, and makes it difficult to promptly detect leaks after installation.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the positioning device for installing a gas valve provided in this embodiment of the utility model includes a bracket 1 and a movable frame 2. One side of the movable frame 2 is slidably connected to the bracket 1 through a slider and a sliding groove. A fixing mechanism 3 is provided on the inner side of the movable frame 2, and a lifting mechanism 6 is provided on the left side of the movable frame 2. A support plate 4 is fixedly installed on the inner side of the movable frame 2, and a gas valve 5 is placed on the top of the support plate 4.

[0022] To fix the gas valve 5, the fixing mechanism 3 includes a first motor 301 fixedly installed on one side of the movable frame 2. The output end of the first motor 301 on the left side passes through the right side of the movable frame 2 and is fixedly connected to a first threaded rod 302. One end of the first threaded rod 302 is rotatably connected to the inner side of the movable frame 2 through a bearing. A clamping plate 303 is slidably connected to the inner side of the movable frame 2 through a slider and a slide groove. The inner wall of the clamping plate 303 is threadedly connected to the surface of the first threaded rod 302. After the first motor 301 is started, it drives the first threaded rod 302 to rotate. Since the clamping plate 303 is slidably connected to the slide groove of the movable frame 2 through the slider, and the inner wall of the clamping plate 303 is threadedly engaged with the threaded rod, the rotation of the threaded rod is converted into the linear movement of the clamping plate 303. By controlling the forward and reverse rotation of the first motor 301, the distance between the two clamping plates 303 can be adjusted, thereby clamping or releasing the gas valve 5.

[0023] To align the gas valve 5 with the pipe opening, the lifting mechanism 6 includes a second motor 601. The bottom of the second motor 601 is fixedly connected to the bracket 1, and a second threaded rod 602 is fixedly connected to the output end of the top of the second motor 601. A fixing block 603 is fixedly connected to the left side of the movable frame 2. One end of the second threaded rod 602 passes through the fixing block 603 and extends upward. The inner wall of the fixing block 603 is threadedly connected to the surface of the second threaded rod 602. The second motor 601 drives the second threaded rod 602 to rotate. The threads on the inner wall of the fixing block 603 engage with the threaded rod, causing the movable frame 2 to move up and down along the axis of the threaded rod. By controlling the speed and direction of the second motor 601, the vertical height of the valve can be precisely adjusted through the movable frame 2 until it is aligned with the pipe interface, which can reduce the physical exertion of the installers.

[0024] To further secure the gas valve 5, a fixing plate 7 is fixedly connected to the top right side of the movable frame 2. A bolt 8 is threadedly connected to the inner wall of the fixing plate 7. The bottom of the bolt 8 passes through the fixing plate 7 and is rotatably connected to a washer 9 through a bearing. The bottom of the washer 9 contacts the gas valve 5. When the bolt 8 is rotated, the bolt 8 moves downward along the threaded hole of the fixing plate 7, and the washer 9 is driven by the bearing to press the top of the gas valve 5, thus forming a double clamping of upper and lower clamping and side clamping in cooperation with the fixing mechanism 3.

[0025] To detect gas leaks in a timely manner, a compression block 15 is fixedly connected to the top of the left clamping plate 303. After the gas valve 5 is installed, the valve can be opened to supply gas. At this time, the first motor 301 is started to make the clamping plate 303 move away from the gas valve 5. When the left clamping plate 303 moves, it will squeeze the water storage box 10 through the compression block 15.

[0026] To detect gas leaks promptly, a water storage box 10 is fixedly connected to the top left side of the movable frame 2. A water outlet pipe 11 is fixedly connected to the right side of the water storage box 10. A first one-way valve 12 is installed on the surface of the water outlet pipe 11, which can only discharge water. A water inlet pipe 13 is fixedly connected to the left side of the water storage box 10. A second one-way valve 14 is installed on the surface of the water inlet pipe 13, which can only allow water to enter. The rubber water storage box 10 is deformed by the squeezing block 15, causing the soapy water stored inside to be sprayed out through the water outlet pipe 11 and the first one-way valve 12 (water only). The soapy water is sprayed onto the interface between the gas valve 5 and the gas pipeline. If a gas leak occurs, it can be detected immediately.

[0027] To improve the practicality of the water storage box 10, the water storage box 10 is made of rubber. The rubber water storage box 10 can automatically return to its original shape after being squeezed, which is simple and practical.

[0028] The working principle of this utility model:

[0029] In use, the first motor 301 and the second motor 601 are connected to an external controller equipped with a PLC control module. The water storage box 10 is then filled with soapy water. The gas valve 5 is placed on top of the support plate 4. The first motor 301 is then started, driving the first threaded rod 302 to rotate. Since the clamping plate 303 is slidably connected to the sliding groove of the movable frame 2 via a slider, and the inner wall of the clamping plate 303 is threadedly engaged with the threaded rod, the rotation of the threaded rod is converted into linear movement of the clamping plate 303. By controlling the forward and reverse rotation of the first motor 301, the distance between the two clamping plates 303 can be adjusted, thereby clamping or releasing the gas valve 5. The second motor 601 drives the second threaded rod 602 to rotate. The threads on the inner wall of the fixed block 603 engage with the threaded rod, causing the movable frame 2 to move up and down along the axis of the threaded rod. The rotation of the second motor 601 is controlled by the rotation of the second threaded rod. The rotation speed and direction of the 601 can be precisely adjusted by the movable frame 2 to adjust the vertical height of the valve until it is aligned with the pipe interface, which can reduce the physical exertion of the installers. Then, the bolt 8 is rotated. When the bolt 8 is rotated, the bolt 8 moves downward along the threaded hole of the fixed plate 7. The bearing drives the washer 9 to press the top of the gas valve 5, which cooperates with the fixed mechanism 3 to form a double clamping of upper and lower clamping and side clamping. After the gas pipeline is installed, the valve can be opened to supply gas. At this time, the first motor 301 is started to make the clamping plate 303 leave the gas valve 5. When the left clamping plate 303 moves, it will squeeze the water storage box 10 through the squeezing block 15. The rubber water storage box 10 is squeezed and deformed by the squeezing block 15, and the soap water stored inside is sprayed out through the water outlet pipe 11 and the first one-way valve 12. The soap water is sprayed onto the interface between the gas valve 5 and the gas pipeline. If a gas leak occurs, it can be detected immediately.
