Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving air valves, in particular to an energy-saving air valve. Background Technique

[0002] An air valve is a component used to control the gas inlet and outlet of a cylinder in a compressor, mainly composed of a valve seat, a valve plate, a spring and a lift limiter.

[0003] For example, a new type of energy-saving air valve with the authorization publication number of "CN214617935U" seals or ventilates the ventilation holes through a rotating disk driving an arc-shaped valve core. During the adjustment process, the ventilation volume can be adjusted, gradually making the ventilation volume smaller or larger, and it can be operated in a reciprocating cycle. The operation is simple and convenient. By setting a bearing seat on the adjustment rotating shaft, the stability of rotation is maintained. The multiple rotating frames and connecting frames set improve the structural stability. However, in the use of the energy-saving air valve, the adjustment of the valve plate is controlled by rotating to fix the limit disk. And the energy-saving air valve needs to be adjusted according to the exhaust volume, which requires reciprocating adjustment of the limit disk. Such operation is more cumbersome and slower, resulting in the energy-saving air valve being unable to close in time, causing some gas to be discharged and wasted, reducing the energy-saving performance of the energy-saving air valve, and at the same time reducing the working efficiency of the energy-saving air valve. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of reducing the energy-saving performance of the energy-saving air valve and at the same time reducing the working efficiency of the energy-saving air valve, and to propose an energy-saving air valve.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design an energy-saving air valve, including a straight pipe and a flange. The front end of the outer wall of the straight pipe is fixedly connected with the inner wall of the flange. A bracket is fixedly connected to the front of the top of the inner wall of the straight pipe. A round block is fixedly connected to the bottom of the bracket. A control structure is connected above the front of the round block. An opening and closing structure is connected to the front of the round block. A compressor is inserted into the rear of the outer wall of the straight pipe.

[0007] Preferably, the control structure includes a straight rod and a ring. The rear of the outer wall of the straight rod is inserted into the round opening above the front of the round block. The outer wall of the straight rod is fixedly connected with the inner wall of the ring. A vertical plate is slidably connected to the front of the outer wall of the straight rod. A compression spring is sleeved on the outer wall of the straight rod. The two ends of the compression spring are respectively fixedly connected with the front of the ring and the rear end face of the vertical plate.

[0008] Preferably, a bent rod is fixedly connected to the front of the straight rod.

[0009] Preferably, a cushion is fixedly connected to the rear end face of the flange.

[0010] Preferably, the opening and closing structure includes a round rod and a round plate. The rear of the outer wall of the round rod is rotatably connected to the front of the round block. The front of the round rod is fixedly connected to the rear end face of the round plate. A torsion spring is sleeved on the outer wall of the round rod. The two ends of the torsion spring are respectively fixedly connected to the front of the round block and the rear end face of the round plate. A curved rod is fixedly connected to the front of the round plate. The bottom of the rear end face of the curved rod is fixedly connected to a valve plate.

[0011] Preferably, the outer wall of the valve plate fits with the inner wall of the straight pipe. The top of the round plate is fixedly connected to the bottom of the vertical plate.

[0012] The beneficial effect of an energy-saving gas valve proposed by the present utility model is as follows: By driving the straight rod forward with the bent rod, the rear of the outer wall of the moving straight rod disengages from the corresponding round opening on the front of the round block. At the same time, the ring on the outer wall of the straight rod squeezes the compression spring. Then, the curved rod drives the round plate to rotate to the left.

Then, release the bent rod. The compression spring provides a resilience force to drive the ring to drive the straight rod to move backward. The rear of the outer wall of the straight rod is inserted into the corresponding round opening, changing the original form of screwing the limit plate, realizing the rapid closing of the valve body, preventing gas leakage, improving the energy-saving performance of the energy-saving gas valve, and improving the working efficiency of the energy-saving gas valve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below with reference to the accompanying drawings:

[0020] Embodiment 1:

[0021] Please refer to Figures 1-5 : In this embodiment, an energy-saving air valve includes a straight pipe 1 and a flange 6. The front end of the outer wall of the straight pipe 1 is fixedly connected to the inner wall of the flange 6. A bracket 4 is fixedly connected to the front of the top of the inner wall of the straight pipe 1. A round block 5 is fixedly connected to the bottom of the bracket 4. A control structure 2 is connected above the front of the round block 5. An opening and closing structure 3 is connected to the front of the round block 5. A compressor 8 is inserted into the rear of the outer wall of the straight pipe 1, and the model of the compressor 8 is selected according to the usage requirements.

[0022] The control structure 2 includes a straight rod 201 and a ring 202. The rear of the outer wall of the straight rod 201 is inserted into the round opening above the front of the round block 5. The outer wall of the straight rod 201 is fixedly connected to the inner wall of the ring 202. A vertical plate 203 is slidably connected to the front of the outer wall of the straight rod 201. The straight rod 201 slides back and forth through the round opening on the outer wall of the vertical plate 203 under force. A compression spring 204 is sleeved on the outer wall of the straight rod 201. The two ends of the compression spring 204 are respectively fixedly connected to the front of the ring 202 and the rear end face of the vertical plate 203. After the ring 202 is forced to move forward, it rebounds through the elastic force of the compression spring 204. A bent rod 205 is fixedly connected to the front of the straight rod 201, and the bent rod 205 facilitates driving the straight rod 201 to move;

[0023] By driving the straight rod 201 forward with the bent rod 205, the rear of the outer wall of the moving straight rod 201 disengages from the corresponding round opening on the front of the round block 5. At the same time, the ring 202 on the outer wall of the straight rod 201 squeezes the compression spring 204. Then, the curved rod 304 drives the round plate 302 to rotate to the left. The rotating round plate 302 drives the round rod 301 to rotate. At the same time, the curved rod 304 drives the valve plate 305 to rotate to the left, opening the inner wall of the straight pipe 1. Then, the bent rod 205 is released, and the compression spring 204 provides a return elastic force to drive the ring 202 to drive the straight rod 201 to move backward. The rear of the outer wall of the straight rod 201 is inserted into the corresponding round opening of the round opening 5, changing the original form of screwing the limiting plate, realizing the rapid closing of the valve body, preventing gas leakage, improving the energy-saving performance of the energy-saving air valve, and improving the working efficiency of the energy-saving air valve.

[0024] A gasket 7 is fixedly connected to the rear end face of the flange 6. The gasket 7 is made of rubber. The opening and closing structure 3 includes a round rod 301 and a round plate 302. The rear of the outer wall of the round rod 301 is rotatably connected to the front face of the round block 5. The round rod 301 rotates through the bearing on the front face of the round block 5 under force. The front face of the round rod 301 is fixedly connected to the rear end face of the round plate 302. A torsion spring 303 is sleeved on the outer wall of the round rod 301. The two ends of the torsion spring 303 are respectively fixedly connected to the front face of the round block 5 and the rear end face of the round plate 302. After the round plate 302 rotates, it rebounds through the resilience of the torsion spring 303. A curved rod 304 is fixedly connected to the front face of the round plate 302. A valve plate 305 is fixedly connected to the bottom of the rear end face of the curved rod 304. The valve plate 305 is a rubber plate. The inner wall of the straight pipe 1 is polished smoothly to reduce the friction with the valve plate 305. At the same time, the rubber material of the valve plate 305 itself can ensure the sealing performance. The outer wall of the valve plate 305 fits with the inner wall of the straight pipe 1. The top of the round plate 302 is fixedly connected to the bottom of the vertical plate 203.

[0025] Working principle:

[0026] Air valve installation:

[0027] Insert the outer wall of the straight pipe 1 into the front interface of the compressor 8 until the gasket 7 behind the flange 6 fits with the front face of the compressor 8. Then, thread the bolt through the flange 6 from right front to back and thread-connect it to the front face of the compressor 8 to complete the installation of the air valve.

[0028] Air valve use:

[0029] Make the bent rod 205 drive the straight rod 201 to move forward. The rear of the outer wall of the moving straight rod 201 disengages from the corresponding round opening on the front face of the round block 5. At the same time, the ring 202 on the outer wall of the straight rod 201 squeezes the compression spring 204. Then, make the curved rod 304 drive the round plate 302 to rotate to the left. The rotating round plate 302 drives the round rod 301 to rotate. At the same time, the curved rod 304 drives the valve plate 305 to rotate to the left to open the inner wall of the straight pipe 1. Then release the bent rod 205. The compression spring 204 provides resilience to drive the ring 202 to drive the straight rod 201 to move backward. The rear of the outer wall of the straight rod 201 is inserted into the corresponding round opening of the round block 5. At this time, the compressor 8 can intake or exhaust air through the straight pipe 1. When closing, just pull the straight rod 201 forward to make the straight rod 201 disengage from the round block 5. The torsion spring 303 provides resilience to drive the round rod 301 to drive the round plate 302 to rotate back. The rotating round plate 302 drives the curved rod 304 to make the valve plate 305 rotate back to complete the closing of the straight pipe 1, avoiding slow closing of the air valve and causing gas leakage, thus realizing energy saving of the air valve.

[0030] Embodiment 2:

[0031] Please refer to Figures 1-5: In this embodiment, an energy-saving air valve further includes a bent plate 9. The rear end faces of the two bent plates 9 are fixedly connected to the left and right sides of the front surface of the round block 5 respectively, and the front end of the inner side of the bent plate 9 is fixedly connected to the outer wall of the round plate 302.

[0032] Working principle:

[0033] When the valve plate 305 rotates, it will also drive the bent plate 9 to rotate. The bent plate 9 can increase the connection points between the round plate 302 and the valve plate 305 to ensure the stability of the valve plate 305.

[0034] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
