Description

Technical Field

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

[0002] With the continuous expansion of urban gas pipeline networks, the demand for valve maintenance, emergency repair, and intelligent management is increasing. Because existing buried gas valves are constantly exposed to humid environments, electric ball valves on the market are unsuitable for underground operation. Therefore, most buried gas valves are manually operated. However, the T-shaped levers of manually operated buried gas valves lack a labor-saving design, requiring operators to expend considerable physical strength to open and close them, especially with high-pressure or large-diameter valves. This severely impacts repair and maintenance efficiency. Furthermore, T-shaped lever operation relies entirely on manual experience, making it impossible to quantify the torque value during valve opening and closing. Excessive force can lead to valve stem twisting, gearbox damage, or scratches on the sealing surface; insufficient force can result in incomplete valve closure and media leakage.

[0003] According to the announcement number CN218625627U, an easy-to-install automatic gas valve opening and closing device includes: an electric actuator, a mounting plate, and a drive rod. The electric actuator is mounted on the upper end face of the mounting plate, and the drive rod is located below the mounting plate. One end of the drive rod passes through the mounting plate and is mounted on the output end of the electric actuator, while the other end of the drive rod is mounted on the gas pipeline valve. Three support rods are evenly arranged on the outer periphery of the mounting plate, and extension rods are installed on the internal threads of the support rods.

[0004] Regarding the aforementioned solutions, the opening and closing of gas pipeline valves are controlled by electric actuators, and installation in different diameters is achieved through the cooperation of support rods and extension rods. However, since the support rods and mounting plates are fixed structures, they cannot be folded, resulting in a large overall size. This not only increases the space occupied during transportation and storage, but also significantly reduces portability due to the inability to fold flexibly, causing inconvenience for on-site workers in carrying and temporarily storing the valves. Utility Model Content

[0005] The purpose of this utility model is to provide an electric opening and closing tool for gas valves to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric opening and closing tool for a gas valve, comprising an electric actuator, wherein the electric actuator is installed on the top of a mounting plate, a drive rod penetrating the mounting plate is installed at the bottom of the electric actuator, a support rod is movably connected at equal angles to the outer periphery of the mounting plate, and an extension rod is internally threaded to the end of the support rod away from the mounting plate; The support rod is rotatably connected to the mounting plate by a support shaft, and the support shaft is used to make the support rod rotate around the shaft. The mounting plate is provided with a positioning mechanism, which is used to prevent the support shaft from rotating on its own.

[0007] Preferably, the positioning mechanism includes a positioning groove formed inside a set of support shafts and a positioning block that is slidably connected to the mounting plate.

[0008] Preferably, the positioning block engages with the positioning groove, and the positioning block and the positioning groove cooperate to achieve positioning of the support shaft.

[0009] Preferably, a return spring is connected between the positioning block and the mounting plate, and the return spring is used to automatically reset the positioning block. A lifting member is fixedly connected to the end of the positioning block away from the positioning groove so that the positioning block can move laterally.

[0010] Preferably, the lifting component includes a lifting rod fixedly connected to the positioning block and a lifting ring fixedly connected to the end of the lifting rod away from the positioning block.

[0011] Preferably, a spline frame is fixedly connected to the bottom end of the mounting plate, and a spline head that engages with the spline frame is fixedly connected to the top end of the drive rod.

[0012] Preferably, the bottom end of the drive rod is provided with a mounting frame to enable the connection between the drive rod and the gas pipeline valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This electric gas valve opening and closing tool allows the support rod to rotate around the support shaft on the outer periphery of the mounting plate during use until the support rod and drive rod are perpendicular, thus unfolding the support rod. It is also positioned by a positioning mechanism to prevent loosening. When carrying, the support rod can rotate in the opposite direction around the support shaft on the outer periphery of the mounting plate until the support rod and drive rod are parallel, thereby reducing its size and significantly improving portability, making it convenient for on-site workers to carry and temporarily store.

After use, the extension rod 5 can be rotated in the opposite direction to move it laterally until it is separated from the inner wall of the valve well. Then, the gas valve electric opening and closing tool can be removed by moving it upward, thus achieving immediate installation.

[0018] Specifically, after the installation of the electric gas valve opening and closing tool is completed, the electric actuator 1 can rotate forward or backward to drive the drive rod 3 installed at its output end through the internal and external splines. At the same time, the rotation of the drive rod 3 can drive the gas pipeline valve connected to it through the mounting frame to rotate, thereby controlling the opening and closing of the gas pipeline valve. The valve can be closed when needed to prevent accidents and can replace manual operation.

[0019] exist Figure 1 , Figure 3 and Figure 4 In the middle: a support shaft 7 is rotatably connected between the support rod 4 and the mounting plate 2.

[0020] Specifically, by rotating the support rod 4, it can be rotated around the axis until it is perpendicular to the drive rod 3, so that the support rod 4 can be unfolded. By rotating the support rod 4 in the opposite direction, it can be rotated around the axis until it is parallel to the drive rod 3, so as to reduce the volume, significantly improve portability, and bring convenience to on-site workers for carrying and temporary storage.

[0021] exist Figures 1-5 In the mounting plate 2, a positioning mechanism 6 is provided inside. The positioning mechanism 6 is used to prevent the support shaft 7 from rotating. The positioning mechanism 6 includes a positioning groove 604 opened inside a set of support shafts 7 and a positioning block 602 slidably connected to the mounting plate 2. The positioning block 602 is engaged with the positioning groove 604. The positioning block 602 and the positioning groove 604 cooperate to achieve positioning of the support shaft 7. A return spring 603 is connected between the positioning block 602 and the mounting plate 2. The return spring 603 is used to make the positioning block 602 automatically return to its original position. A lifting member 601 is fixedly connected to the end of the positioning block 602 away from the positioning groove 604. The lifting member 601 is used to move the positioning block 602 laterally.

[0022] Specifically, since the support shaft 7 and the mounting plate 2 are engaged by the positioning block 602 and the positioning groove 604, and the positioning block 602 and the mounting plate 2 are slidably connected by the lifting member 601, after the gas valve electric opening and closing tool is carried to the designated position, the positioning block 602 can be disengaged from the positioning groove 604 by pulling the lifting member 601 to one end. At this time, the support rod 4 is rotated to make it rotate around the axis until it is perpendicular to the drive rod 3. Then, the lifting member 601 is released, so that the positioning block 602 will automatically reset under the action of the return spring 603 and engage with the positioning groove 604, thereby achieving automatic positioning after unfolding and preventing loosening.

[0023] Specifically, since the support rod 4 and the mounting plate 2 are rotatably connected through the support shaft 7, the positioning block 602 can be disengaged from the positioning groove 604 by pulling the lifting member 601 to one end. At this time, the support rod 4 is rotated in the opposite direction to make it rotate around the shaft until it is parallel to the drive rod 3. Then, the lifting member 601 is released, so that the positioning block 602 will automatically reset under the action of the return spring 603 and engage with the positioning groove 604, thereby achieving automatic positioning after unfolding and preventing loosening.

[0024] exist Figures 2-4 In the middle: the lifting component 601 includes a lifting rod fixedly connected to the positioning block 602 and a lifting ring fixedly connected to the end of the lifting rod away from the positioning block 602.

[0025] Specifically, by pulling the pull ring outward, the positioning block 602 is moved horizontally via the lifting rod until the positioning block 602 separates from the positioning groove 604.

[0026] After the gas valve electric opening and closing tool is carried to the designated position, the positioning block 602 can be disengaged from the positioning groove 604 by pulling the lifting member 601 to one end. At this time, the support rod 4 can be rotated around the axis until it is perpendicular to the drive rod 3. Then, the lifting member 601 is released, so that the positioning block 602 will automatically reset under the action of the return spring 603 and engage with the positioning groove 604, thereby achieving automatic positioning after unfolding and preventing loosening. Next, the installation plate 2 is placed in the completed valve well, and the extension rod 5 is rotated to move it laterally until it is in close contact with the inner wall of the valve well, so as to complete the installation according to the diameter. When controlling the opening and closing of the valve, the electric actuator 1 rotates forward or backward, which can drive the drive rod 3 installed at its output end through the internal spline and external spline to rotate. At the same time, the rotation of the drive rod 3 can drive the gas pipeline valve connected to it through the installation frame to rotate, thereby controlling the opening and closing of the gas pipeline valve. The valve can be closed when needed to prevent accidents. After use, the extension rod 5 is rotated in the opposite direction to move it laterally until it is separated from the inner wall of the valve well.
