Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure control, in particular to a novel gas pressure automatic controller. Background Art

[0002] New gas is a newly developed type of gas in my country, an emerging energy source that benefits hundreds of millions of households. However, its development and promotion across the country has been stagnant for many years, hindering widespread adoption. The fundamental reason is that the gas generators are still not fully developed, with numerous issues, particularly regarding gas pressure regulation.

[0003] A search revealed a new automatic gas pressure controller with publication number CN2306418Y. This controller consists of an air chamber and a control chamber. A shrinkable metal sheet is placed between the two chambers. A contact switch is installed in the control chamber. This utility model overcomes many difficulties and issues encountered in promoting new gas systems, ensuring stable and adjustable air pressure and facilitating automated control. This utility model reduces electromechanical losses and oil backflow, protecting the gas pump from oil erosion caused by return fuel. It overcomes the weaknesses of gas pressure reducing valves. Furthermore, the metal sheet used in the center is more resistant to oil and dirt corrosion and more durable than a rubber film.

[0004] However, the above controller still has some shortcomings during use. The air pressure is monitored and controlled by the metal sheet, and the accuracy is poor. The upper and lower limits of the air pressure that need to be controlled cannot be adjusted according to actual conditions. It cannot automatically control and adjust, and is inconvenient to use. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a new type of gas pressure automatic controller, which solves the problems of monitoring and controlling the gas pressure through metal sheets, poor accuracy, inability to adjust the upper and lower limits of the gas pressure to be controlled according to actual conditions, inability to automatically control and adjust, and inconvenience in use.

[0006] The utility model provides the following technical solutions: a new type of gas pressure automatic controller, including a control box and three control components, a rotating rod is rotatably connected between the internal top wall and the bottom wall of the control box, a closed baffle is fixedly sleeved on the surface of the rotating rod, the closed baffle matches the inner wall of the control box, and the closed baffle can close the control box, a pressure gauge is provided on the upper surface of the control box, a probe is provided on the lower surface of the pressure gauge, the probe extends to the interior of the control box for monitoring, a dial is provided inside the pressure gauge, a pointer is rotatably installed on the surface of the dial, and scale lines are provided on the surface of the dial.

[0007] Preferred technical solution 1: The control component includes a magnetic tile, a micro photoelectric switch is fixedly installed on the surface of the magnetic tile, and a light shielding sheet is fixedly installed on the surface of the pointer. The three control components are divided into a high-voltage control component, a low-voltage control component, and a voltage-stabilizing control component.

[0008] Preferred technical solution 2: The dial is made of magnetic material, the magnetic patch can be adsorbed on the dial, the surface of the barometer is provided with a transparent light-transmitting protective shell, and three wiring holes are opened on the upper surface of the barometer.

[0009] Preferred technical solution three: the top end of the rotating rod extends to the outside of the control box and is fixedly sleeved with a driven gear, the upper surface of the control box is fixedly connected to a mounting bracket, the upper surface of the mounting bracket is fixedly installed with a driving motor, the output end of the driving motor is fixedly connected to a driving gear, and the driving gear is meshed with the driven gear.

[0010] Preferred technical solution four: Both ends of the control box are connected to an air inlet pipe and an air outlet pipe respectively, and one end of the air inlet pipe and the air outlet pipe are fixedly installed with a fixing flange.

[0011] Preferred technical solution five: A mounting plate is fixedly connected to the lower surface of the control box, a plurality of mounting holes are provided on the surface of the mounting plate, and the three control components are electrically connected to the drive motor.

[0012] Compared with the prior art, the utility model provides a new type of gas pressure automatic controller, which has the following beneficial effects: when in use, the three control components are installed in the appropriate positions on the dial through magnetic adsorption, the high-pressure control component is installed at the upper limit of the air pressure, the low-pressure control component is installed at the lower limit of the air pressure, and the pressure-stabilizing control component is installed at a position where the air pressure is moderate. When the air pressure is stable, the pointer on the barometer points to the position of the micro-photoelectric switch on the pressure-stabilizing control component, so that the shading sheet blocks it, and the driving motor stops working at this time. When the air pressure is low or high, the air pressure is monitored by the barometer probe. The pointer drives the shading piece to move. When the shading piece moves to the position of the low-pressure and high-pressure control components, the shading piece blocks the micro-photoelectric switch. At this time, the drive motor works to drive the active gear and the driven gear to rotate, thereby driving the closed baffle to rotate, expanding or reducing the gas passage inside the control box, thereby controlling the output gas pressure. When the controlled gas pressure reaches the appropriate pressure value, the pointer drives the shading piece to move to the position of the voltage stabilizing control component, thereby blocking the micro-photoelectric switch. At this time, the drive motor stops working and controls the gas pressure to be stable. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating rod 2 is rotatably connected between the internal top wall and bottom wall of the control box 1. A closed baffle 3 is fixedly sleeved on the surface of the rotating rod 2. The closed baffle 3 matches the inner wall of the control box 1. The closed baffle 3 can seal the control box 1. A pressure gauge 4 is provided on the upper surface of the control box 1, and a probe 5 is provided on the lower surface of the pressure gauge 4. The probe 5 extends to the interior of the control box 1 for monitoring. A dial 6 is provided inside the pressure gauge 4, and a pointer 7 is rotatably installed on the surface of the dial 6. The surface of the dial 6 is provided with scale lines 8.

[0019] Example 2: The difference between this example and Example 1 is that the control component 9 includes a magnetic tile 10, a micro photoelectric switch 11 is fixedly installed on the surface of the magnetic tile 10, and a light shielding sheet 12 is fixedly installed on the surface of the pointer 7. The three control components 9 are divided into a high-voltage control component, a low-voltage control component, and a voltage-stabilizing control component, which facilitates the control of the air pressure through the control component 9.

[0020] Example 3: The difference between this example and Example 1 is that the dial 6 is made of magnetic material, the magnetic patch 10 can be adsorbed on the dial 6, the surface of the barometer 4 is provided with a transparent light-transmitting protective shell, and three wiring holes are opened on the upper surface of the barometer 4 to facilitate the installation of the control component 9 and protection.

[0021] Embodiment 4: The difference between this embodiment and embodiment 1 is that the top end of the rotating rod 2 extends to the outside of the control box 1 and is fixedly sleeved with a driven gear 13, the upper surface of the control box 1 is fixedly connected with a mounting bracket 14, the upper surface of the mounting bracket 14 is fixedly installed with a driving motor 15, the output end of the driving motor 15 is fixedly connected with a driving gear 16, and the driving gear 16 is meshed with the driven gear 13, so that the rotating rod 2 and the closed baffle 3 can be automatically driven to rotate by the rotation of the driving motor 15, so that the air pressure can be adjusted and controlled.

[0022] Example 5: The difference between this example and Example 1 is that the two ends of the control box 1 are respectively connected to the air inlet pipe 18 and the air outlet pipe 19, and one end of the air inlet pipe 18 and the air outlet pipe 19 are fixedly installed with a fixing flange 20 to facilitate the sealing connection between the controller and the pipeline.

When the air pressure is stable, the pointer 7 on the barometer 4 points to the position of the micro-photoelectric switch 11 on the voltage-stabilizing control component, so that the shading plate 12 blocks it. At this time, the driving motor 15 stops working. When the air pressure is low or high, the air pressure is monitored by the barometer 4 probe 5, so that the pointer 7 drives the shading plate 12 to move in. When the shading plate 12 moves to the position of the low-pressure and high-pressure control components, the shading plate 12 blocks the micro-photoelectric switch 11. At this time, the driving motor 15 works to drive the active gear 16 and the driven gear 13 to rotate, thereby driving the closed baffle 3 to rotate, and expanding or reducing the gas passage inside the control box 1, thereby controlling the output air pressure. When the controlled air pressure reaches the appropriate air pressure value, the pointer 7 drives the shading plate 12 to move to the position of the voltage stabilizing control component, thereby blocking the micro-photoelectric switch 11. At this time, the driving motor 15 stops working and controls the air pressure to be stable.
