Description

Technical Field

[0001] The invention relates to the technical field of solenoid valves, and in particular to an adjustable explosion-proof solenoid valve. Background Art

[0002] A solenoid valve is a valve that uses the electromagnetic principle to control the flow of fluid through a pipeline. It is mainly composed of an electromagnetic coil, an iron core, a valve body, a valve seat, a valve core and other components. The working principle is that when the electromagnetic coil is energized, a magnetic field is generated, which attracts the iron core to move, thereby driving the valve core to move and realize the opening or closing of the valve. There are many types of solenoid valves, one of which is a flameproof solenoid valve, which is specially designed for flammable and explosive environments. It can prevent sparks or high temperatures that may be generated inside from causing explosions in the external environment. It is suitable for high-risk industries such as petrochemicals and coal mines.

[0003] In the existing patent CN220060667U, a new type of explosion-proof solenoid valve is disclosed, which relates to the field of solenoid valves. The utility model includes a water-proof plate and an air pipe. A flameproof mechanism is arranged on one side of the water-proof plate. The flameproof mechanism includes a sleeve. A collapse block is arranged inside the sleeve. The utility model sets a flameproof mechanism, including a flameproof plate. When an explosion occurs at the output end of the gas passage, an impact force will be generated in the pipeline. At this time, the impact force will quickly push the flameproof plate back. Then, since a card block is arranged on one side of the flameproof plate, the card block will enter the sealing groove and be stuck by the movable block, so the flameproof plate can be effectively stuck to prevent the flameproof plate from rebounding. Then, since a soft pad is arranged inside the sealing groove, part of the impact can be buffered to avoid pipeline damage. At the same time, it can play a sealing effect to prevent the gas after combustion from entering the subsequent pipeline through the wind and causing a chain explosion.

[0004] In the above structure, the sealing effect of the device can be achieved. However, when the gas burns, the gas explodes and generates a shock wave. The shock wave will damage the solenoid valve and related components, making it impossible to protect the solenoid valve, resulting in damage to the solenoid valves upstream and downstream of the pipeline, thereby reducing the solenoid valve's ability to resist impact. At the same time, the shock wave will carry burning gas, causing a chain explosion, which greatly reduces the ability to protect the solenoid valve and reduces the service life of the solenoid valve.

When the shock wave generates an impact, it will generate a force on the anti-pressure component, and the anti-pressure component moves to drive the resistance component to move. After the resistance component contacts the control component, it forces the control component to move to contact with the valve seat, thereby closing the ventilation of the connecting pipe.

At this time, the anti-pressure component continues to move, forcing the anti-pressure component to drive the sealing component to seal the connecting pipe, so that the sealing component and the anti-pressure component block the shock wave and the burning gas. At this time, due to the synchronous movement of the gas driven by the shock wave, a high-pressure sealed environment is formed in the connecting pipe. The anti-pressure component drives the fire extinguishing component to operate and release carbon dioxide gas. At this time, the decompression component is connected to the connecting pipe. Due to the high pressure, the gas in the sealed environment enters the decompression component. The pressure component causes the pressure reduction component to expand, forcing the pressure reduction component to be connected to the exhaust component, the pressure-resistant component synchronously drives the transmission component to move, and the transmission component drives the exhaust component to move, releasing the gas in the pressure reduction component, so that the gas in the sealed environment in the connecting pipe is released, further avoiding the explosion caused by high pressure. When the gas in the connecting pipe is released to a reasonable state, the pressure reduction component will return to its original state, thereby disconnecting the connection between the connecting pipe and the exhaust component. At the same time, the fire extinguishing component is used to detect the carbon dioxide gas, so that the staff can know the situation in the connecting pipe and deal with it in time. In summary, an adjustable explosion-proof solenoid valve of the present application can buffer the shock wave and reduce the impact force of the shock wave when the gas burns and explodes. After being acted upon by the shock wave, a sealed protective environment is formed to achieve a blocking effect on the gas. At the same time, the gas can be decompressed, which can protect the device and avoid explosion in the connecting pipe due to the sealed high-pressure environment. The impact resistance of the device is improved, and the shock wave is effectively avoided. The burning gas forms a chain explosion phenomenon, thereby improving the protection capability of the device and improving the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Working principle: During normal ventilation, the solenoid valve body 301 is started to force the valve stem 302 to move. When the valve seat 2 is closed, the valve stem 302 is forced to move downward to drive the contact block 1 303 to move. The contact block 1 303 drives the contact block 2 404 to move horizontally close to the valve seat 2, so that the contact block 2 404 drives the control rod 402 to move. The control rod 402 drives the valve plate 403 to move, so that the valve plate 403 moves close to the valve seat 2. When the valve plate 403 is in close contact with the valve seat 2, the valve seat 2 is closed. At this time, the control spring 406 is compressed; when the valve stem 302 is forced to move upward to drive the contact block 1 303 to move, it drives the contact block 2 404 The control rod 402 moves away from the valve seat 2 horizontally, so that the contact block 2 404 drives the control rod 402 to move back, and the control rod 402 drives the valve plate 403 to move back, and the control spring 406 returns to its original state until the valve plate 403 is separated from the valve seat 2, thereby realizing the opening of the valve seat 2 and achieving the control and regulation effect of the on-off of the gas; when a gas combustion explosion occurs at a certain point in the pipeline, a shock wave will be generated, and the shock wave will drive the burning gas to impact the upstream and downstream pipelines. When the shock wave generates an impact, the shock wave will generate a force on the force-bearing plate 604, and the force-bearing plate 604 will move, and the force-bearing plate 604 will drive the anti-pressure rod 603 to move, and the anti-pressure rod 603 will drive The pressure-resistant piston 602 moves in the gas storage cylinder 601, so that the pressure-resistant piston 602 pushes the gas in the gas storage cylinder 601 to move, the pressure-resistant spring 605 is compressed, and the gas drives the resistance piston 801 to move, so that the resistance piston 801 drives the resistance rod 802 to move, and the resistance rod 802 drives the resistance block 803 to move, so that the resistance block 803 resists the contact block 2 404, forcing the contact block 2 404 to move, until the contact block 2 404 drives the control rod 402 to move, forcing the control rod 402 to drive the valve plate 403 to be in close contact with the valve seat 2, thereby achieving the closing effect on the valve seat 2 and disconnecting the ventilation effect of the connecting pipe 1; when the resistance piston 80 When the piston 801 moves to the maximum, the abutting piston 801 does not move; at this time, the one-way valve 703 is opened, and the shock wave drives the pressure-resistant piston 602 to continue to move. The pressure-resistant piston 602 will squeeze the gas in the gas storage cylinder 601. Under the action of the conduit 702, the gas in the gas storage cylinder 601 is led out to the sealing airbag 701, so that the sealing airbag 701 expands until the sealing airbag 701 expands to contact the inner wall of the connecting pipe 1, so that a sealed environment is formed between the sealing airbag 701, the force plate 604, the connecting pipe 1, the valve plate 403 and the valve seat 2, so that the sealing airbag 701 and the force plate 604 block the shock wave and the burning gas;As the shock wave drives the gas to move synchronously, a high-pressure sealed environment is formed in the connecting pipe 1, and the movement of the force-bearing plate 604 drives the puncture needle 1202 to move, so that the puncture needle 1202 punctures the glass bottle 1201, causing the glass bottle 1201 to break, and the carbon dioxide in the glass bottle 1201 is released, so that the carbon dioxide is introduced into the sealed environment. At the same time, the decompression air inlet pipe 906 connects the connecting pipe 1 with the decompression cylinder 901. Due to the high pressure, the gas in the sealed environment enters the decompression cylinder 901, so that the gas in the decompression cylinder 901 increases and the pressure increases, so that the gas drives the decompression piston 902 to move and drives the decompression rod 903 to move. The decompression rod 903 forces the decompression spring 905 to stretch, forcing the decompression cylinder to communicate with the exhaust pipe 1001; at the same time, the force-bearing plate 604 drives the horizontal spur rack 1102 to move, and the horizontal spur rack 1102 drives the transmission gear 1101 to rotate. The moving gear 1101 drives the vertical spur rack 1103 to move, so that the vertical spur rack 1103 drives the connecting rod 1005 to move, and the connecting rod 1005 drives the volume control plate 1003 to move, so that the exhaust hole 1004 on the volume control plate 1003 corresponds to the exhaust pipe 1001, so that the gas is led out from the connecting pipe 1 to the pressure reducing cylinder 901, and then led out to the exhaust pipe 1001 through the pressure reducing cylinder 901, and exhausted to the air through the exhaust pipe 1001, further avoiding the explosion caused by high pressure; when the gas in the connecting pipe 1 is released to a reasonable state, under the action of the pressure reducing spring 905, the pressure reducing piston 902 and the pressure reducing rod 903 are restored to their original state, thereby disconnecting the connection between the connecting pipe 1 and the exhaust pipe 1001, and at the same time using the carbon dioxide detector 1203 to detect the carbon dioxide gas, the staff can know the situation in the connecting pipe 1 in time and deal with it in time. ;
