[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Please refer to Figures 1-4 The present application provides a technical solution:

[0026] A gas self-closing valve, comprising a valve body 1, a valve plate 2 is rotatably arranged in the valve body 1, a vertical rod 3 is rotatably arranged on the top of the valve body 1, the rotating shaft end of the vertical rod 3 is fixedly installed with the rotating shaft end of the valve plate 2, air inlet pipes 4 and air outlet pipes 5 are respectively fixedly connected on both sides of the valve body 1, a pressure gauge 6 is arranged on the air inlet pipe 4, cross plates 7 are fixedly installed on the air inlet pipe 4 and the air outlet pipe 5, a motor 8 is fixedly installed on one side of the cross plate 7, a driving wheel 9 is fixedly installed on the output shaft end of the motor 8, a driven wheel 10 is fixedly installed on the vertical rod 3, a belt 11 is sleeved on the driving wheel 9 and the driven wheel 10, and the belt 11 is drivingly connected with the driving wheel 9 and the driven wheel 10.

[0027] In use, the inlet pipes 4 and outlet pipes 5 on both sides of the valve body 1 are connected to the gas delivery pipes. The pressure gauge 6 on the inlet pipe 4 is used to detect the pressure during the gas delivery process. When the pressure gauge 6 detects an abnormal pressure (such as overpressure or underpressure), the motor 8 fixedly installed on one side of the horizontal plate 7 is started. The motor 8 starts to run, and the drive wheel 9 fixedly installed at the end of its output shaft rotates accordingly. Since the drive wheel 9 and the driven wheel 10 are fitted with belts 11, and the belts 11 are respectively connected to the drive wheel 9 and the driven wheel 10 for transmission, the drive wheel 9 rotates while the driven wheel 10 rotates. Wheel 9 drives driven wheel 10 to rotate via belt 11. Driven wheel 10 is fixedly installed on vertical rod 3, which in turn drives vertical rod 3 to rotate. The shaft end of vertical rod 3 is fixedly installed with the shaft end of valve plate 2, which is rotatably installed inside valve body 1. When vertical rod 3 rotates, it drives valve plate 2 to rotate, realizing the automatic opening or closing of valve body 1. This gas self-closing valve can automatically open and close valve body 1, simplifying the manual intervention process, reducing the difficulty of operation, and enhancing the safety and convenience of gas use. The device has a simple overall structure, is easy to operate, and is highly practical.

[0028] A handle 12 is fixedly installed at the top of the vertical rod 3, and an indicator arrow is provided on the handle 12.

[0029] When it is necessary to manually operate the valve body 1, the operator can hold the handle 12 fixedly installed at the top of the vertical rod 3. Since the rotating shaft end of the vertical rod 3 is fixedly installed with the rotating shaft end of the valve plate 2 inside the valve body 1, when the handle 12 is turned, the vertical rod 3 rotates accordingly, thereby driving the valve plate 2 to rotate, realizing the opening or closing of the valve body 1. The indicator arrow set on the handle 12 can help the operator to more intuitively understand the rotation direction of the valve plate 2 and the current opening and closing status of the valve body 1, thus improving the applicability of the device.

[0030] A support plate 13 is fixedly installed between the two sets of horizontal plates 7, and the vertical rod 3 and the output shaft of the motor 8 are both rotatably mounted on the support plate 13;

[0031] The support plate 13 provides additional support points for the vertical rod 3 and the output shaft of the motor 8, which can reduce the shaking and offset of the vertical rod 3 and the output shaft of the motor 8 during rotation, improve their rotational stability, and enable the valve plate 2 to more accurately realize the opening and closing action, thereby improving the stability of the valve plate 2's opening and closing.

[0032] The valve body 1 is spherical, the valve plate 2 is circular, and the size of the valve plate 2 is adapted to the inner diameter of the valve body 1;

[0033] The valve body 1 is spherical, and the valve plate 2, which is rotatably mounted inside the valve body 1, is circular. The size of the valve plate 2 is adapted to the inner diameter of the valve body 1. When the valve plate 2 is rotated to the closed position, the circular valve plate 2 can perfectly fit the inner wall of the spherical valve body 1, reducing the gaps for gas leakage and thus improving the sealing effect of the valve plate 2 on the valve body 1, effectively preventing gas leakage in the closed state.

[0034] The sealing rubber ring 14 is fixedly installed on the side edge of the valve plate 2;

[0035] When the valve plate 2 rotates to the closed position, the sealing rubber ring 14 is pressed between the side edge of the valve plate 2 and the inner wall of the valve body 1. The sealing rubber ring 14 has elasticity and can fill the small gap between the valve plate 2 and the inner wall of the valve body 1, further preventing gas leakage. In addition, the sealing rubber ring 14 can also act as a buffer to reduce friction and collision between the valve plate 2 and the inner wall of the valve body 1, prolonging the service life of the valve plate 2 and the valve body 1, and further improving the sealing effect of the valve plate 2 on the valve body 1.

[0036] A controller is arranged on one side of the horizontal plate 7, and the controller is electrically connected with the pressure gauge 6 and the motor 8 respectively;

[0037] The controller arranged on the horizontal plate 7 can automatically control the opening and closing of the valve body 1.

[0038] Working principle:

[0039] In use, the inlet pipe 4 and the outlet pipe 5 on both sides of the valve body 1 are respectively connected with the pipeline for delivering gas. The pressure gauge 6 on the inlet pipe 4 is used to detect the pressure during the gas delivery process. When the pressure gauge 6 detects abnormal pressure (such as overpressure or underpressure), the motor 8 fixedly installed on one side of the horizontal plate 7 is started, and the motor 8 starts to operate. The driving wheel 9 fixedly installed at the output shaft end of the motor 8 rotates. Since the driving wheel 9 and the driven wheel 10 are sleeved with the belt 11, and the belt 11 is respectively in transmission connection with the driving wheel 9 and the driven wheel 10, the driving wheel 9 drives the driven wheel 10 to rotate through the belt 11. The driven wheel 10 is fixedly installed on the vertical rod 3, and further drives the vertical rod 3 to rotate. The rotating shaft end of the vertical rod 3 is fixedly installed with the rotating shaft end of the valve plate 2 arranged in the valve body 1. When the vertical rod 3 rotates, the valve plate 2 rotates, and the automatic opening and closing of the valve body 1 is realized. The self-closing valve can automatically open and close the valve body 1, simplifies the manual intervention process, reduces the operation difficulty, enhances the safety and convenience of gas use, and has simple overall structure, convenient operation and strong practicality.

[0040] Among them,

[0041] When it is necessary to manually operate the opening and closing of the valve body 1, the operator can hold the steering handle 12 fixedly installed at the top end of the vertical rod 3. Since the rotating shaft end of the vertical rod 3 is fixedly installed with the rotating shaft end of the valve plate 2 in the valve body 1, when the steering handle 12 rotates, the vertical rod 3 rotates, and further drives the valve plate 2 to rotate, realizing the opening or closing of the valve body 1. The indication arrow arranged on the steering handle 12 can help the operator to more intuitively understand the rotating direction of the valve plate 2 and the current opening and closing state of the valve body 1, improving the applicability of the device.

[0042] The support plate 13 provides additional support points for the vertical rod 3 and the output shaft of the motor 8, which can reduce the shaking and deviation of the vertical rod 3 and the output shaft of the motor 8 during rotation, improve the stability of their rotation, so that the valve plate 2 can more accurately realize the opening and closing action, and improve the stability of the opening and closing of the valve plate 2.

[0043] The valve body 1 is provided as a spherical shape, the valve plate 2 provided to rotate in the valve body 1 is provided as a circular shape, and the size of the valve plate 2 is adapted to the inner diameter size of the valve body 1. When the valve plate 2 rotates to the closed position, the circular valve plate 2 can perfectly fit with the inner wall of the spherical valve body 1, reducing the gap of gas leakage, thereby improving the sealing effect of the valve plate 2 on the valve body 1, effectively preventing gas leakage in the closed state.

[0044] The sealing rubber ring 14 is fixedly installed on the side edge of the valve plate 2. When the valve plate 2 rotates to the closed position, the sealing rubber ring 14 is pressed between the side edge of the valve plate 2 and the inner wall of the valve body 1. The sealing rubber ring 14 has elasticity, which can fill the possible small gap between the valve plate 2 and the inner wall of the valve body 1, further prevent gas leakage, and the sealing rubber ring 14 can also play a buffering role, reduce the friction and collision between the valve plate 2 and the inner wall of the valve body 1, prolong the service life of the valve plate 2 and the valve body 1, and further improve the sealing effect of the valve plate 2 on the valve body 1.

[0045] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
