DETAILED DESCRIPTION

[0029] Example 1

[0030] As Figures 1-6As shown, a gas storage tank for gas supply, comprising a tank body 1 made of high-strength metal material, such as high-quality carbon steel or stainless steel, to ensure that it has sufficient pressure resistance and structural stability to withstand the pressure of the internal gas, the outer side of the tank body 1 is provided with a gas inlet 2 and a gas outlet 3, the gas inlet 2 is located below the tank body 1, and the gas outlet 3 is located above the tank body 1, the gas inlet 2 and the gas outlet 3 are both high-strength metal pipes, and are connected with the tank body 1 by welding or flange connection, wherein the gas inlet 2 is used to connect the external gas source to receive compressed air from the outside; the gas outlet 3 is connected with the gas supply pipeline of the gas using equipment to deliver the stored and pressure stabilized gas to the gas using equipment. When connected, ensure firm connection and good sealing performance to avoid gas leakage.

[0031] The inside of the tank body 1 is provided with a pressure stabilizing mechanism 4 for ensuring the stability of the gas pressure inside the tank body 1, which specifically comprises a vertical guide rail 40 and a piston plate 41, wherein the piston plate 41 is an aluminum alloy plate or a stainless steel plate, and it is a circular plate matched with the tank body 1, and the piston plate 41 divides the inside of the tank body 1 into an upper gas chamber and a lower gas chamber.

[0032] The vertical guide rail 40 is fixed on the inner wall surface of the tank body 1, and the number is not less than two, the vertical guide rail 40 specifically comprises a vertical rod 401, the vertical rod 401 is provided with a sliding limiting groove 402 near both edges of the side close to the inner wall surface of the tank body 1, it should be noted that the both ends of the sliding limiting groove 402 are closed.

[0033] In this embodiment, the vertical guide rail 40 can be fixed by welding or bolt connection, and the number is preferably two, and is symmetrically distributed, it should be noted that when installing, the position and perpendicularity of the vertical rod 401 should be ensured to be accurate.

[0034] The outer edge of the piston plate 41 is provided with a groove 42 opposite to the vertical guide rail 40, and a guide slider 43 slidingly installed on the vertical guide rail 40 is embedded in the groove 42, the guide slider 43 specifically comprises a slider body 430, and the slider body 430 is provided with a convex sliding groove 431 which can be sleeved outside the vertical guide rail 40, so that it can slide on the vertical rod 401, and at the same time prevent disengagement.

[0035] In the preferred scheme, a plurality of rolling balls 433 in contact with the vertical rod 401 are arranged on the inner wall surface of the convex sliding groove 431 to reduce the sliding friction and ensure that the piston plate 41 can slide flexibly on the vertical guide rail 40.

[0036] The side of the slider body 430 close to the inner wall surface of the tank body 1 is provided with a sealing gasket 432 movably attached thereto to ensure the sealing between the piston plate 41 and the inner wall surface of the tank body 1 when moving up and down, preventing gas leakage from the gap.

[0037] The piston plate 41 is provided with a plurality of air holes 410.

[0038] In this way, as the gas in the tank increases, the pressure in the tank changes, and when the pressure of the upper and lower air chambers is unbalanced, the piston plate 41 slides up and down along the vertical guide rail 40 under the action of the pressure difference.

[0039] When the pressure in the tank increases: the inlet continues to intake, so that the pressure in the tank increases, at this time the pressure of the lower air chamber is greater than that of the upper air chamber, and the pressure difference pushes the piston plate 41 to move upwards. With the upward movement of the piston plate 41, the relative position of the air hole 410 on the piston plate 41 and the upper air chamber changes, the actual air area of the air hole decreases, so that the air volume decreases, which can slow down the speed of gas flowing from the lower air chamber to the upper air chamber, avoid the rapid rise of the pressure in the tank, and play a role in stabilizing the pressure.

[0040] When the pressure in the tank decreases: when the outlet supplies gas, the gas in the tank decreases, and the pressure decreases. The pressure of the upper air chamber is greater than that of the lower air chamber, and the piston plate 41 moves downward under the action of the pressure difference. With the downward movement of the piston plate 41, the relative position of the air hole 410 and the upper air chamber changes, the actual air area of the air hole 410 increases, the air volume increases, and more gas can flow from the upper air chamber to the lower air chamber, thereby stabilizing the pressure in the tank and avoiding excessive pressure drop.

[0041] Therefore, by floating up and down according to the change of the pressure in the tank, the air volume of the air hole 410 is adjusted in real time, so that the gas tank can effectively maintain the stability of the pressure in the tank when facing the frequent start-stop of the gas equipment or the large change of the gas flow, ensure the smoothness of the gas supply pressure, and improve the quality of the printing and embossing process.

[0042] The outer side of the piston plate 41 is further provided with a sealing ring 411 which is movably attached to the inner wall of the tank body 1, which further enhances the sealing performance between the piston plate 41 and the tank body 1, and ensures that the gas flow between the upper and lower air chambers is only through the air hole 410, thereby accurately controlling the air volume.

[0043] It should be noted that the sealing ring 411 and the sealing gasket 432 are wear-resistant rubber.

[0044] In the preferred embodiment, as Figure 3As shown, the vent hole 410 includes a center vent hole arranged at the center of the piston plate 41, and a plurality of annularly distributed edge vent holes arranged between the center vent hole and the outer ring edge, wherein the diameter of the center vent hole is the smallest, and the diameters of the plurality of annularly distributed edge vent holes gradually increase from inside to outside. In this way, the air flow adjustment is more linear and sensitive. When the piston plate 41 is in different floating positions, the actual vent area of the vent hole 410 changes, resulting in different air flow. At the same time, due to the larger area of the edge region hole, when the piston plate 41 moves to the edge region, more gas can be quickly released or supplemented, while the center region provides more precise air flow adjustment.

[0045] Specifically, when the piston plate 41 moves upward, in the initial stage, the piston plate 41 is close to the center position: the vent hole 410 has a small area, and the air flow increases slowly, so that the pressure change is more accurate; as the piston plate 41 continues to move upward, more large holes start to participate in the ventilation, and the air flow increases rapidly, effectively balancing the high pressure in the tank.

[0046] When the piston plate 41 moves downward, in the initial stage, the piston plate 41 is close to the center position: the small hole diameter limits the gas supplementing speed, avoiding rapid pressure drop, and as the piston plate continues to move downward, the edge large hole starts to supplement more gas, speeding up the pressure recovery process.

[0047] Through this gradient type design, the air flow adjustment process is smoother, avoiding the sudden air flow changes that may occur in the uniform distribution hole design.

[0048] In the preferred embodiment, the piston plate 41 is provided with a plurality of collision buffering mechanisms 44 on the upper and lower sides, the collision buffering mechanisms 44 are equidistantly arranged on the edge of the outer side of the piston plate 41, and the inner wall surface of the tank body 1 is provided with two groups of symmetrically arranged abutting plates 445 corresponding to the collision buffering mechanisms 44 on the upper and lower sides of the piston plate 41.

[0049] In this embodiment, the piston plate 41 is provided with four collision buffering mechanisms 44 on the upper and lower sides, and the number of abutting plates 445 is matched with the corresponding collision buffering mechanisms 44, for preventing impact collision caused by too fast movement of the piston plate 41.

[0050] The collision buffering mechanism 44 includes an outer sleeve seat 440 with an open top, and a buffering abutting block 443 movably inserted into the outer sleeve seat 440 through the opening. The opposite two inner wall surfaces of the outer sleeve seat 440 are provided with limiting grooves 441, the bottom of the buffering abutting block 443 is provided with a limiting block 444 in sliding cooperation with the limiting grooves 441, and the outer sleeve seat 440 is further provided with a telescopic spring 442 abutting against the buffering abutting block 443 at the end, so that the buffering abutting block 443 can move along the limiting groove 441 under the action of the telescopic spring 442.

[0051] In use, when the piston plate 41 moves up and down on the vertical guide rail 40, the buffer abutting block 443 will abut and buffer with the abutting plate 445 provided on the inner wall surface of the tank body 1 under the elastic action of the telescopic spring 442, so as to avoid the piston plate 41 directly colliding with the inner wall of the tank body 1, reduce the impact and wear, and prolong the service life of the piston plate 41 and the tank body 1.

[0052] Embodiment 2

[0053] Further illustrated in combination with Embodiment 1, as shown in the structure, Figure 2 and 7 the inner wall surface of the tank body 1 is further provided with an air inlet buffer mechanism 5 opposite to the air inlet 2, so that when the compressed air enters the tank body 1 from the air inlet 2, the airflow first impacts the air inlet buffer mechanism 5 for relieving the impact when the air is inhaled.

[0054] The air inlet buffer mechanism 5 includes a plurality of buffer units 50, in this embodiment, the number of buffer units 50 is three, adjacent buffer units 50 are connected through a folded rubber sheet 51, the buffer unit 50 includes an arc-shaped plate 501 and a plurality of supporting springs 502 provided on the back of the arc-shaped plate 501, wherein the arc-shaped plate 501 is a rubber plate, the other end of the supporting spring 502 is fixedly provided on the inner wall surface of the tank body 1, so that the arc-shaped plate 501 can be elastically deformed under the elastic action of the supporting spring 502, and the folded rubber sheet 51 is provided between the arc-shaped plates 501 of adjacent buffer units 50, which ensures that adjacent units can act cooperatively to form an overall air inlet buffer structure when the buffer unit 50 is deformed.

[0055] In a preferred scheme, the side of the arc-shaped plate 501 facing the air inlet 2 is provided with a grid guide groove to better guide and disperse the airflow.

[0056] Working principle:

[0057] When the external compressed air enters the tank body 1 from the air inlet 2, the airflow first impacts the air inlet buffer mechanism 5, the airflow will cause the arc-shaped plate 501 to be deformed under the action of the supporting spring 502, and the folded rubber sheet 51 will also be stretched and contracted at the same time, the impact force of the airflow is dispersed through the elastic deformation of the spring and the rubber sheet, the airflow speed is slowed down, the sudden inflow of the airflow is avoided to cause the tank pressure to fluctuate greatly, and the airflow after being buffered by the air inlet buffer mechanism 5 enters the tank body 1, and the tank pressure starts to rise.

[0058] With the increase of the gas in the tank, the pressure in the tank will change. Since the piston plate 41 divides the tank body into two air chambers above and below, when the pressures of the upper and lower air chambers are unbalanced, the piston plate 41 will slide up and down along the vertical guide rail 40 under the action of the pressure difference.

[0059] When the piston plate 41 moves upward, the relative position of the vent hole 410 on the piston plate 41 and the upper and lower air chambers changes, and the venting amount decreases, because the central vent hole has the smallest diameter, the edge vent holes gradually expand from inside to outside, and the upward movement of the piston plate 41 gradually covers the smaller vent holes, thereby limiting the flow of gas from the lower air chamber to the upper air chamber, slowing down the rising speed of the pressure in the tank; on the contrary, when the piston plate 41 moves downward, the venting amount increases, and more gas can flow from the lower air chamber to the upper air chamber through the vent hole 410, thereby replenishing the pressure and maintaining the stability of the pressure in the tank.

[0060] During the upward and downward movement of the piston plate 41, the guide slider 43 slides along the vertical rod 401, the ball bearings 433 in the convex sliding groove 431 can reduce the sliding friction, the sealing gasket 432 ensures the sealing, and the buffer abutting block 443 in the impact buffer mechanism 44 abuts against the abutting plate 445 under the action of the extension spring 442, thereby avoiding the rigid collision between the piston plate 41 and the inner wall surface of the tank body 1.

[0061] When the gas equipment needs gas, the gas in the tank is output through the gas outlet 3, at this time, the pressure in the tank decreases, the piston plate 41 moves downward according to the pressure difference, adjusts the venting amount of the vent hole 410, and makes the gas in the tank flow from the lower air chamber to the upper air chamber through the vent hole 410, so as to maintain the pressure in the tank within a stable range and ensure the stable gas supply pressure to provide stable gas supply for the gas equipment.

[0062] Through the above specific embodiments, the gas supply tank can effectively realize the buffering of the inlet gas and the stable adjustment of the pressure in the tank, and ensure the stable gas supply for the gas equipment such as clothing printing and embossing, and improve the quality and stability of the printing and embossing process.

[0063] The above embodiments are only preferred technical solutions of the present application, and should not be regarded as limiting the present application, and the protection scope of the present application should be the technical solutions recited in the claims, including the equivalent replacement solutions of the technical features recited in the claims. That is, the equivalent replacement improvement within this range is also within the protection scope of the present application.
