The right surface of the plate 34 is fixedly connected, the right surface of the connecting pipe 3 is fixedly connected to the accommodating tank 4, the exhaust hole 33 and the polyurethane film 35 are both semicircular in shape and matched in position, the top of the gas tank body 1 near the middle is fixedly connected to the air intake pipe 11, the top of the gas tank body 1 near the right side is installed with a safety valve 2, the bottom of the gas tank body 1 near the rear side is fixedly connected to the exhaust pipe 12, the bottom of the gas tank body 1 near the front side is fixedly connected to the drain pipe 13, the front surface of the drain pipe 13 is installed with a drain valve 22, the front surface of the gas tank body 1 is installed with a pressure gauge 21, and the bottom of the gas tank body 1 is equidistantly fixedly connected to a plurality of supporting legs 14.

[0023] The effect achieved by the entire embodiment 1 is that when the device is used, when the gas enters the gas storage tank body 1 through the air inlet pipe 11, the gas is compressed and stored in the gas storage tank body 1. As the gas continues to enter, the pressure inside the gas storage tank body 1 gradually increases. The pressure value of the gas in the gas storage tank body 1 can be displayed in real time through the pressure gauge 21 outside the gas storage tank body 1, so that the operator can intuitively understand the pressure condition in the gas storage tank body 1. When the gas pressure exceeds the maximum value that the gas storage tank body 1 can withstand, the motor 36 is started. Under the action of the motor 36, the second circular plate 34 on the mounting frame 31 can be driven to rotate, thereby driving the polyurethane film 35 on the second circular plate 34 to rotate synchronously, and the first The position of the polyurethane film 35 on the second circular plate 34 can correspond to the position of the exhaust hole 33 on the first circular plate 32. At this time, part of the air pressure in the gas tank body 1 can be discharged into the polyurethane film 35 through the connecting pipe 3. Since the material of the polyurethane film 35 has excellent toughness and strength, part of the air pressure will expand the polyurethane film 35 inside the receiving tank 4. At this time, the air pressure inside the gas tank body 1 can be relieved, thereby reducing the risks of deformation of the gas tank body 1 due to excessive air pressure, cracking of the weld, gas leakage, etc., which ensures the use effect and safety of the gas tank body 1 to a certain extent. At the same time, it can also be used in conjunction with the safety valve 2 on the top of the gas tank body 1.

The device effectively improves the pressure resistance and safety of the gas tank body 1 through the innovative polyurethane film 35 pressure relief mechanism. Safety. In the case of overpressure, the automatically started motor 36 drives the system to quickly adjust the position of the polyurethane film 35 to achieve precise pressure relief, avoiding the risk of damage to the gas tank body 1 due to excessive air pressure. At the same time, with the double protection of the safety valve 2, the stable operation of the system is further ensured. The elastic recovery ability of the polyurethane film 35 ensures its reusability and reduces maintenance costs. In addition, the regular sewage discharge function ensures the cleanliness of the inside of the gas tank body 1, extends the service life of the equipment, and improves the overall operating efficiency. The support legs 14 play a role in supporting the device, and the exhaust pipe 12 is used to discharge excess gas in the gas tank body 1 to control the pressure in the gas tank body 1 within a safe and appropriate range.

[0024] Example 2: Figure 1-Figure 4As shown, a limit ring 53 is fixedly connected to the inner wall of the air inlet pipe 11 near the bottom, a filter plate 5 is provided on the top of the limit ring 53, a fixing rod 51 is fixedly connected to the top of the filter plate 5, and a handle 52 is fixedly connected to the top of the fixing rod 51.

[0025] The effect achieved by the entire embodiment 2 is that when the gas enters the gas tank body 1, it will first pass through the filter plate 5 on the limiting ring 53, which is convenient for filtering out dust, impurities, particulate matter, etc. in the air, making the gas entering the gas tank body 1 purer, preventing impurities from entering the gas tank body 1, and preventing impurities from being deposited in the tank and corroding the inside of the tank body, thereby extending the service life of the gas tank body 1. When cleaning, the fixing rod 51 is pulled by the handle 52 to drive the filter plate 5 to clean it, which is easy to operate.

[0026] Working principle: When using this device, when the gas enters the gas tank body 1 through the air inlet pipe 11, the gas is compressed and stored in the gas tank body 1. As the gas continues to enter, the pressure inside the gas tank body 1 gradually increases. The pressure value of the gas in the gas tank body 1 can be displayed in real time through the pressure gauge 21 outside the gas tank body 1. When the gas pressure exceeds the maximum value that the gas tank body 1 can withstand, under the action of the motor 36, the second circular plate 34 on the mounting frame 31 rotates, thereby driving the polyurethane film 35 on the second circular plate 34 to rotate synchronously, and the position of the polyurethane film 35 on the second circular plate 34 can correspond to the position of the exhaust hole 33 on the first circular plate 32. At this time, the gas tank body 1 Part of the air pressure inside can be discharged into the polyurethane film 35 through the connecting pipe 3, and part of the air pressure will expand the polyurethane film 35 inside the containing tank 4. At this time, the air pressure inside the gas tank body 1 can be relieved, thereby reducing the risks of deformation of the gas tank body 1 due to excessive air pressure, cracking of the weld, gas leakage, etc., which ensures the use effect and safety of the gas tank body 1 to a certain extent. At the same time, it can also be used in conjunction with the safety valve 2 on the top of the gas tank body 1. When the system pressure exceeds the set value, the safety valve 2 will automatically open to discharge excess medium, so that the system pressure returns to a safe range, further protecting the safety of equipment and personnel. When the partial pressure relief is completed, the polyurethane film 35 can rebound and recover after stretching and deformation. The second circular plate 34 is rotated by the motor 36 to make the polyurethane film 35 thereon return to the original position staggered with the exhaust hole 33. After long-term use, more moisture may accumulate at the bottom of the gas tank body 1. The water can be discharged by regularly opening the drain valve 22 on the drain pipe 13 to ensure the cleanliness of the inside of the gas tank body 1. The device effectively improves the pressure resistance and safety of the gas tank body 1 through the innovative polyurethane film 35 pressure relief mechanism. In the case of overpressure, the automatically started motor 36 drive system quickly adjusts the position of the polyurethane film 35 to achieve precise pressure relief, avoiding the risk of damage to the gas tank body 1 due to excessive air pressure. At the same time, with the double protection of the safety valve 2, it is further ensured. The stable operation of the system is ensured, and the elastic recovery ability of the polyurethane film 35 ensures its reusability and reduces the maintenance cost. In addition, the regular sewage discharge function ensures the cleanliness of the inside of the gas tank body 1, extends the service life of the equipment, and improves the overall operation efficiency. Moreover, when the gas enters the inside of the gas tank body 1, it will first pass through the filter plate 5 on the limit ring 53 to filter out dust, impurities, particulate matter, etc. in the air, so that the gas entering the gas tank body 1 is purer, and impurities are prevented from entering the gas tank body 1, and impurities are prevented from being deposited in the tank and corroding the inside of the tank body, thereby extending the service life of the gas tank body 1. When cleaning, the fixing rod 51 is pulled by the handle 52 to drive the filter plate 5 to clean it, which is easy to operate.
