DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a structure for regulating pressure of a gas tank, and the device includes: a gas tank unit 100, and a gas pressure regulating unit 200.

[0034] The gas tank unit 100 includes a gas tank body 101, a gas conveying member 102 disposed on one side of the gas tank body 101, a fixing member 103 disposed at the bottom of the gas tank body 101, and a connecting flange 104 disposed on the other side of the gas tank body 101. When the internal pressure of the gas tank body 101 is normal and in normal use, the gas tank body 101 is stored in the gas tank body 101 by compressed gas, and the internal pressure needs to be monitored. When the external temperature changes and causes the internal pressure to increase, the conveying component 201 and the regulating component 202 will The pressure relief procedure is automatically started, and the first, second and even third level pressure relief is performed in sequence through the regulating component 202 to keep the pressure within a safe range. After the pressure relief, the regulating component 202 will automatically reset to maintain the airtightness of the gas tank. When the gas is used, the gas is supplied to the required equipment by opening the pneumatic conveying component 102. In addition, regular maintenance inspections and emergency treatment measures are also important components to ensure the safe operation of the gas tank body 101. The conveying component 201 and the regulating component 202 ensure the safe and efficient operation of the entire gas tank body 101 in different environments; The air pressure regulating unit 200 includes a conveying component 201 arranged at the other end of the connecting flange 104, a regulating component 202 arranged at the other end of the conveying component 201, and a barometer 203 arranged at the top of the conveying component 201. When the internal air pressure of the gas tank body 101 is abnormal, and the internal air pressure of the gas tank body 101 is greater than that of the outside, the gas inside the gas tank body 101 will increase. During the gas increase process, the gas will be squeezed, so that the gas inside the gas tank body 101 is squeezed into the conveying component 201. When the gas passes through the conveying component 201, the air pressure inside the conveying component 201 can be observed by the barometer 203 to know the air pressure state inside the gas tank body 101. At the same time, the squeezed gas inside the conveying component 201 is pressed into the regulating component 202. The gas inside the gas tank body 101 squeezes the regulating component 202. When the gas squeezes the regulating component 202, the air cushion inside the regulating component 202 The gas cushion 202d is squeezed by the gas in the regulating assembly 202 and moves with the gas, so that the gas can enter the inside of the regulating ring 202b. At the same time, the gas entering the regulating ring 202b is pressed into the pressure relief ring 202c, and the gas is initially adjusted by the pressure relief ring 202c to start pressure relief. If the pressure inside the gas storage tank body 101 is still very high at this time, the pressure relief ring 202c cannot meet the pressure regulation inside the gas storage tank body 101, and the gas continues to squeeze the air cushion 202 d, so that the air cushion 202d is completely separated from the pressure relief ring 202c, and the gas enters the interior of the fixed ring 202g, and the secondary pressure relief adjustment is performed with the cooperation of the air cushion 202i. When the air pressure inside the gas tank body 101 begins to be lower than the external air pressure, the air cushion 202d is returned to the interior of the adjustment ring 202b under the action of the external air pressure and the return spring 202f, so as to ensure the overall sealing of the gas tank body 101 and the safety of the use of the gas tank body 101.

[0035] During use, when the internal air pressure of the gas tank body 101 is abnormal, the internal air pressure of the gas tank body 101 is greater than that of the outside, and the gas inside the gas tank body 101 will increase. During the gas increase process, the gas will be squeezed, so that the gas inside the gas tank body 101 is squeezed into the conveying component 201. When the gas passes through the conveying component 201, the air pressure inside the conveying component 201 can be observed by the barometer 203 to know the air pressure state inside the gas tank body 101. At the same time, the squeezed gas inside the conveying component 201 is pressed into the regulating component 202. The gas inside the gas tank body 101 squeezes the regulating component 202. When the gas squeezes the regulating component 202, the regulating component 202 The internal air cushion 202d is squeezed by the gas inside the regulating component 202 and moves with the gas, so that the gas can enter the inside of the regulating ring 202b. At the same time, the gas entering the regulating ring 202b is pressed into the pressure relief ring 202c, and the gas is preliminarily adjusted by the pressure relief ring 202c to start pressure relief. If the pressure inside the gas tank body 101 is still very high at this time and the pressure relief ring 202c cannot meet the pressure regulation inside the gas tank body 101, the gas continues to squeeze the air cushion 202d, so that the air cushion 202d is completely separated from the pressure relief ring 202c, and the gas enters the inside of the fixed ring 202g, and with the cooperation of the air cushion 202i, the secondary pressure relief regulation is performed, or even the tertiary pressure relief is performed to adjust the pressure inside the gas tank body 101.

[0036] When the air pressure inside the gas tank body 101 begins to be lower than the external air pressure, the air cushion 202d returns to the inside of the adjustment ring 202b under the action of the external air pressure and the return spring 202f, so as to ensure the overall sealing of the gas tank body 101 and the safety of use of the gas tank body 101, and can monitor the internal pressure in real time through the pressure gauge 203, and when the pressure exceeds the safety threshold, the conveying component 201 and the regulating component 202 work together to perform the first, second and even third level pressure relief in sequence to adjust the internal air pressure in stages, which not only ensures the safety and sealing of the gas tank 101 under different pressure conditions, but also improves the response speed and flexibility to pressure changes, and extends the service life of the equipment.

[0037] Example 2, reference Figure 1 - Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a delivery assembly 201 includes a detection tube 201a arranged on one side of the connecting flange 104, a delivery tube 201b arranged at the other end of the detection tube 201a, and a fixed tube 201c arranged at the other end of the delivery tube 201b. When the gas tank body 101 is in an external environment, the internal air pressure of the gas tank body 101 increases after an abnormality occurs through the gas inside the gas tank body 101 itself, causing the gas to be squeezed into the inside of the detection tube 201a. The gas is squeezed into the inside of the delivery tube 201b through the detection tube 201a. At the same time, the gas pressure inside the gas tank body 101 can be clearly seen by observing the pressure gauge 203 on the top of the detection tube 201a and the delivery tube 201b, and the gas enters the inside of the regulating assembly 202, and the regulating assembly 202 regulates and releases the pressure of the air entering the inside to ensure the stability of the pressure inside the gas tank body 101.

[0038] Compared with Example 1, further, a sealing gasket 201d is provided on the outer diameter of the detection tube 201a, and the sealing gasket 201d is connected to the connecting flange 104. The connection between the sealing gasket 201d and the connecting flange 104 ensures the safety and sealing of the gas tank body 101, and can monitor the internal pressure in real time through the pressure gauge 203. When the pressure exceeds the safety threshold, the conveying component 201 and the regulating component 202 work together to perform the first, second and even third level pressure relief in sequence to adjust the internal air pressure in stages, which not only ensures the safety and sealing of the gas tank body 101 under different pressure conditions, but also enhances the service life and use environment of the gas tank body 101.

[0039] During use, when the gas tank body 101 is in an external environment, the internal air pressure of the gas tank body 101 increases after an abnormality occurs, resulting in the gas being squeezed into the inside of the detection tube 201a, and the gas is squeezed into the inside of the delivery tube 201b through the detection tube 201a. At the same time, the gas pressure inside the gas tank body 101 can be clearly seen by observing the pressure gauge 203 on the top of the detection tube 201a and the delivery tube 201b, and the gas enters the inside of the regulating component 202, and the regulating component 202 adjusts the gas entering the inside. The pressure is adjusted and released to ensure the pressure inside the gas tank body 101 is stable. At the same time, the connection between the sealing gasket 201d and the connecting flange 104 ensures the safety and sealing of the gas tank body 101, and the internal pressure can be monitored in real time through the pressure gauge 203. When the pressure exceeds the safety threshold, the conveying component 201 and the regulating component 202 work together to perform the first, second and even third level pressure relief in sequence to adjust the internal air pressure in stages, which not only ensures the safety and sealing of the gas tank body 101 under different environmental conditions, but also enhances the service life of the gas tank body 101.

[0040] The remaining structures are the same as those of Example 1.

[0041] Example 3, reference Figure 1 - Fig.13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the adjustment component 202 includes a connecting bolt 202a arranged on the fixed tube 201c, an adjusting ring 202b arranged on the outer diameter of the connecting bolt 202a, a pressure relief ring 202c arranged on the outer diameter of the adjusting ring 202b, and an air cushion 202d slidably arranged inside the adjusting ring 202b, the outer diameter of the adjusting ring 202b is provided with a fixing ring 202g, and an air cushion 202i is provided on one side of the inner side of the fixing ring 202g, and the air cushion 202d is provided on the outer diameter of the adjusting ring 202b. A moving rod 202e is provided on 202i, and a return spring 202f is provided on the outer diameter of the moving rod 202e, and the other end of the return spring 202f is connected to the air cushion 202d. When the internal air pressure of the gas storage tank body 101 is abnormal, the gas inside the gas storage tank body 101 will increase. In the process of increasing the gas, the gas inside the gas storage tank body 101 will be squeezed into the conveying component 201, and when the gas passes through the conveying component 201, it can be observed by observing the barometer 203 that the gas storage tank body 101 is 01, and the gas is squeezed into the regulating assembly 202. When the gas enters the connecting bolt 202a, the gas inside the gas storage tank body 101 begins to squeeze the air cushion 202d, so that the air cushion 202d is squeezed out from the inside of the regulating ring 202b. As the air cushion 202d moves, the gas is separated from the connecting bolt 202a and squeezed into the inside of the regulating ring 202b. The gas enters the pressure relief ring 202c through the exhaust hole set on the outer diameter of the regulating ring 202b. The pressure relief ring 202c The gas inside the gas tank body 101 is initially adjusted to start the first-level pressure relief. If the external pressure is greater than the internal pressure of the gas tank body 101, the air cushion 202d returns to the inside of the adjustment ring 202b under the push of the external pressure and the return spring 202f, thereby ensuring the overall sealing of the gas tank body 101. At the same time, under the limit of the moving rod 202e, the air cushion 202d can accurately enter the inside of the adjustment ring 202b for sealing, thereby ensuring the adjustment of the internal pressure of the gas tank body 101.

[0042] Compared with Example 2, further, a connecting block 202i-1 is provided on one side of the air cushion 202i, a buckle 202i-2 is provided on the other side of the connecting block 202i-1, and the buckle 202i-2 is slidably connected to the moving rod 202e, a limiting ring 202h is provided on the other side of the air cushion 202i, a sealing gasket 202h-1 is provided inside the limiting ring 202h, and the sealing gasket 202h-1 cooperates with the air cushion 202i, and an adjusting ring 202j is provided on one side of the limiting ring 202h, and the air cushion 202i is adjusted on the adjusting ring. When the pressure relief ring 202c is performing preliminary adjustment on the pressure inside the gas tank body 101, if the pressure inside the gas tank body 101 continues to rise, and the pressure relief ring 202c cannot meet the pressure adjustment inside the gas tank body 101, the gas inside the adjusting ring 202b will continue to squeeze the air cushion 202d, so that the air cushion 202d and the moving rod 202e are squeezed into the inside of the limiting ring 202h by the gas. When the air cushion 202d is squeezed into the inside of the fixing ring 202g, the pressure inside the adjusting ring 202b is The gas will quickly rush into the interior of the fixing ring 202g, and at the same time enter the adjusting ring 202j through the exhaust hole set on the air cushion 202i. At the same time, the moving rod 202e and the return spring 202f are squeezed into the limiting ring 202h by the gas, and the buckle 202i-2 limits the moving rod 202e to ensure the gas circulation inside the gas storage tank body 101. After entering the adjusting ring 202j, the gas begins to be depressurized at the second level through the return spring 202k, and the pressure inside the gas storage tank body 101 is further adjusted. Ring 202j cooperates with the pressure relief ring 202c to regulate the gas pressure relief at the same time to ensure that the air pressure inside the gas tank body 101 is stable. After the air pressure inside the gas tank body 101 is lower than the external air pressure, the moving rod 202e slides out of the buckle 202i-2, and then the air cushion 202d is pushed back to the inside of the adjusting ring 202b by the return spring 202f to seal the inside of the gas tank body 101 again, ensuring the overall sealing and stability of the gas tank body 101, so that the air pressure inside the gas tank body 101 can be adjusted.

[0043] Furthermore, a return spring 202k is provided inside the adjusting ring 202j, and the other end of the return spring 202k is connected to the air cushion 202i. A discharge ring 202l is provided on the outer diameter of the adjusting ring 202j, and the discharge ring 202l is connected to the limit ring 202h. If the gas inside the gas storage tank body 101 is adjusted and the first-level and second-level adjustments cannot meet the internal air pressure adjustment of the gas storage tank body 101, the gas inside the gas storage tank body 101 continues to squeeze the air cushion 202i, and the air cushion 202i is released from the limit, so that the air cushion 202i slides into the adjusting ring 202j with the air cushion 1 202d, and squeezes the return spring 202k, so that the gas inside the fixing ring 202g is directly squeezed into the internal cavity of the adjusting ring 202j, and the outer diameter of the adjusting ring 202j is adjusted. The discharge port arranged on the upper part begins to release pressure to the greatest extent to adjust the pressure inside the gas tank body 101, and at the same time, the sealing gasket 202h-1 ensures the sealing inside the limit ring 202h when adjusting the gas, and the adjusting ring 202j and the air cushion 202i cooperate with the pressure relief ring 202c in multiple stages to perform graded adjustment on the inside of the gas tank body 101 to ensure the internal air pressure of the gas tank body 101 is stable. After the internal gas of the gas tank body 101 is lower than the external air pressure, the air cushion 202i returns to the limit ring 202h under the action of the external air pressure and the return spring 202k, and at the same time, the air cushion 202d also returns to the inside of the pressure relief ring 202c under the action of the external air pressure and the return spring 202f, thereby completing the stability and sealing of the overall air pressure inside the gas tank body 101.

[0044] During use, when the internal air pressure of the gas tank body 101 is abnormal, the gas inside the gas tank body 101 will increase. During the process of increasing the gas, the gas inside the gas tank body 101 will be squeezed into the conveying assembly 201. When the gas passes through the conveying assembly 201, the air pressure inside the gas tank body 101 can be known by observing the barometer 203. At the same time, the gas is squeezed into the regulating assembly 202. When the gas enters the connecting bolt 202a, the gas inside the gas tank body 101 is squeezed into the regulating assembly 202. The gas inside the gas tank body 101 begins to squeeze the air cushion 202d, so that the air cushion 202d is squeezed out from the inside of the adjusting ring 202b. As the air cushion 202d moves, the gas detaches from the connecting bolt 202a, is squeezed into the inside of the adjusting ring 202b, and enters the pressure relief ring 202c through the exhaust hole set on the outer diameter of the adjusting ring 202b. The pressure relief ring 202c relieves the pressure of the gas, makes preliminary adjustments to the gas inside the gas tank body 101, and starts the first-level pressure relief.

[0045] If the pressure inside the gas tank body 101 continues to rise and the pressure relief ring 202c is unable to meet the pressure regulation inside the gas tank body 101, the gas inside the adjusting ring 202b will continue to squeeze the air cushion 202d, so that the air cushion 202d and the moving rod 202e are squeezed into the interior of the limiting ring 202h by the gas. When the air cushion 202d is squeezed into the interior of the fixing ring 202g, the gas inside the adjusting ring 202b will quickly rush into the interior of the fixing ring 202g and enter the adjusting ring 202j through the exhaust hole provided on the air cushion 202i. At the same time, the moving rod 202e and the return spring 202f are squeezed into the interior of the limiting ring 202h by the gas, and the buckle 202i-2 limits the moving rod 202e to ensure the gas circulation inside the gas tank body 101. After entering the adjusting ring 202j, the gas begins to perform secondary pressure relief through the return spring 202k.

[0046] If, when adjusting the gas inside the gas tank body 101, both the first-level and second-level adjustments cannot meet the internal air pressure adjustment of the gas tank body 101, the gas inside the gas tank body 101 continues to squeeze the air cushion 202i, and the air cushion 202i releases the limit, so that the air cushion 202i slides into the adjusting ring 202j with the air cushion 1 202d, and squeezes the return spring 202k, so that the gas inside the fixed ring 202g is directly squeezed into the internal cavity of the adjusting ring 202j, and the pressure inside the gas tank body 101 is adjusted to the maximum extent by releasing the pressure through the discharge port provided on the outer diameter of the adjusting ring 202j. At the same time, the sealing gasket 202h-1 ensures the sealing inside the limit ring 202h when adjusting the gas, and the adjusting ring 202j and the air cushion 202i cooperate with the pressure relief ring 202c in multiple stages to adjust the gas tank body. The interior of the gas tank body 101 is adjusted in stages to ensure that the internal air pressure of the gas tank body 101 is stable. After the internal gas of the gas tank body 101 is less than the external air pressure, the air cushion 202i returns to the limit ring 202h under the action of the external air pressure and the return spring 202k. At the same time, the air cushion 202d also returns to the inside of the pressure relief ring 202c under the action of the external air pressure and the return spring 202f, thereby completing the stability and sealing of the overall air pressure inside the gas tank body 101. Through the coordinated work of the adjustment component 202, the first, second and even third levels of pressure relief are performed in turn to adjust the internal air pressure in stages, which not only ensures the safety and sealing of the gas tank body 101 under different pressure conditions, but also improves the response speed and flexibility to pressure changes, extends the service life of the equipment, and enhances the adaptability and reliability of the gas tank body 101 under various environmental conditions.

[0047] The remaining structure is the same as that of Example 2.
