Description

Technical Field

[0001] This utility model relates to the field of gas storage tanks, specifically a high-stability gas storage tank sealing mechanism. Background Technology

[0002] When using a gas storage tank, the interface of the gas storage tank needs to be connected to the external pipeline. Although a sealed structure was used before, and a sealing gasket was used for sealing, the elasticity of the sealing gasket gradually deteriorates after a long period of use, and the sealing performance deteriorates.

[0003] like Figure 4 As shown in document CN 218441789 U, a high-sealing gas storage tank is disclosed, including a gas storage tank body. A quick-connect interface is fixedly connected internally to the gas storage tank body. Two support frames are fixedly connected to the surface of the gas storage tank body. A drain valve is fixedly connected internally to the gas storage tank body. A pressure gauge is threadedly connected internally to the gas storage tank body. A sealing structure is provided on the surface of the quick-connect interface. The sealing structure includes a sealing gasket located on the surface of the quick-connect interface. A positioning frame is mounted on the surface of the sealing gasket. The positioning frame has a U-shaped cross-section, and a pressure rod is slidably inserted inside the positioning frame. While this structure can achieve a sealing effect to a certain extent, due to the properties of the sealing gasket, when it is bent upwards, a certain arc will inevitably be generated at the bend. This arc will create a gap between the gasket and the gas storage tank, affecting the sealing performance.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses a highly stable gas storage tank sealing mechanism. By inserting reinforcing gaskets between sealing gaskets and in the gaps of the gas storage tank, the gaps caused by the arc shape of the sealing gaskets themselves are reduced, effectively improving the overall sealing performance of the device and increasing the working efficiency of gas transmission.

[0006] The technical solution of this utility model is: a high-stability gas storage tank sealing mechanism, including a sealing structure located on the gas storage tank. The sealing structure includes a sealing gasket located at the gas outlet end of the gas storage tank. The sealing gasket is unfolded into a rectangle. The sealing gasket is wrapped around the gas storage tank interface without overlapping. A compression rod is provided on the sealing gasket. The compression rod is located near the contact position of the sealing gasket. A reinforcing sealing gasket is provided at the bottom of the position where the sealing gasket is released. A protrusion is provided on the outer surface of the sealing gasket. The sealing gasket is fastened by a fastening structure.

[0007] By adopting the above technical solution, when the gas storage tank is connected to external equipment, a reinforcing gasket is inserted at the overlapping position of the sealing gasket, and then it is fastened by a fastening structure. When the sealing gasket is pressed tightly onto the gas storage tank, the outer surface of the sealing gasket has an upward protrusion, which can play an anti-slip role when the pressure plate squeezes the sealing gasket.

[0008] Preferably, the extrusion rod is L-shaped outward and perpendicular to the tangent direction of the outer surface of the sealing gasket. The middle part of the sealing gasket surrounds the interface of the gas storage tank and overlaps outward at the junction. The extrusion rod is located outside the overlap, and the extrusion rod and the overlap are 2-4 cm outward.

[0009] By adopting the above technical solution, the extrusion rod can leave room for inward compression between the sealing gaskets, making the compression between the sealing gaskets tighter and preventing air leakage.

[0010] Preferably, the L-shaped compression rods are arranged in opposite directions, with the compression rods located at the center line of the sealing gasket along its length.

[0011] By adopting the above technical solution, the position of the extrusion rod can be such that when the extrusion rod is subjected to force, the force is evenly concentrated towards the center and they come together.

[0012] Preferably, a gap is provided between the overlapping position of the sealing gasket and the interface of the gas storage tank, and a reinforcing sealing gasket is provided at the bottom of the sealing gasket to fit the gap.

[0013] By adopting the above technical solution, a reinforced sealing gasket is provided at the internal position between the overlapping sealing gaskets, which makes the connection between the sealing gasket and the gas tank interface tighter and prevents gas leakage.

[0014] Preferably, the cross-sectional shape of the reinforcing gasket is similar to a triangle, with all three sides of the triangle being inwardly concave arcs, and the inwardly concave arcs are adapted to the shape of the gas tank interface and the overlapping part of the gasket.

[0015] By adopting the above technical solution, the reinforced sealing gasket can be perfectly adapted to the arc shape of the sealing gasket and the gas tank interface, so that the reinforced sealing gasket itself will not exert too much outward squeezing force on the sealing gasket, and the connection between the reinforced sealing gasket and the sealing gasket is tighter.

[0016] Preferably, the distance between the three sides of the triangle approaches the intersection and then decreases infinitely, with the end of the intersection being the edge. When closed, the sealing gasket is infinitely compressed to strengthen the sealing gasket, and there is no gap between the sealing gasket and the strengthening sealing gasket.

[0017] By adopting the above technical solution, the thickness of the sealing gasket on the outside is minimized, which reduces the gap between the sealing gasket and the gas tank interface, making them more compatible.

[0018] Preferably, the surface of the sealing gasket has an upward protrusion, which is 2-4 mm higher than the surface of the sealing gasket and is concentrated around the area where it overlaps with the sealing gasket.

[0019] By adopting the above technical solution, the upward protrusion can prevent slippage when the pressure plate squeezes the gasket, increase the friction between the gasket and the pressure plate, and effectively improve the squeezing force of the pressure plate on the gasket.

[0020] Preferably, the fastening structure includes a pressure plate and bolts and nuts. The pressure plate is pressed against the junction of the gasket overlapping upwards and wrapping around the gas tank interface. Bolt holes are provided at both ends of the pressure plate, and the pressure plate is fastened by bolts and nuts.

[0021] By adopting the above technical solution, the pressure plate can squeeze the sealing gasket, effectively preventing gaps from appearing between the sealing gasket and the gas tank interface.

[0022] The advantages of this utility model are as follows: 1. By inserting reinforced sealing gaskets between the sealing gaskets and in the gaps of the gas storage tank, this utility model reduces the gaps caused by the arc shape of the sealing gaskets themselves, effectively improving the overall sealing performance of the device and increasing the working efficiency of gas transmission.

[0023] 2. The present invention has outward protrusions on the outer surface of the sealing gasket. When the sealing gasket is tightened, the pressure plate presses on both sides of the sealing gasket. The friction between the pressure plate and the outer surface of the sealing gasket can prevent the pressure plate from shifting outward outside the sealing gasket and improve the sealing performance of the device.

[0024] 3. This utility model sets the reinforcing sealing gasket in a triangular shape, which perfectly matches the arc of the sealing gasket and the interface of the gas tank, greatly increasing the sealing performance of the sealing gasket to the gas tank interface. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-3 As shown, the high-stability gas storage tank 1 sealing mechanism includes a sealing structure located on the gas storage tank 1. The sealing structure includes a sealing gasket 3 located at the gas outlet end of the gas storage tank 1. The sealing gasket 3 is rectangular in shape when fully unfolded. The sealing gasket 3 is wrapped around the interface 2 of the gas storage tank 1 without overlapping. The sealing gasket 3 is provided with a compression rod 6, which is located near the contact position of the sealing gasket 3. A reinforcing sealing gasket 5 is provided at the bottom of the release position of the sealing gasket 3. The outer surface of the sealing gasket 3 has protrusions. The sealing gasket 3 is fastened by a fastening structure. When the gas storage tank 1 is connected to an external device, the reinforcing sealing gasket 5 is inserted at the overlapping position of the sealing gasket 3, and then it is fastened by the fastening structure so that the sealing gasket 3 can be tightly pressed onto the gas storage tank 1. The outer surface of the sealing gasket 3 has upward protrusions, so that when the pressure plate 7 squeezes the sealing gasket 3, it can play an anti-slip role.

[0032] The extrusion rod 6 is L-shaped and perpendicular to the tangent of the outer surface of the sealing gasket 3. The middle part of the sealing gasket 3 surrounds the interface 2 of the gas storage tank 1 and overlaps with it outward at the junction. The extrusion rod 6 is located on the outside of the overlap. The extrusion rod 6 and the overlap are 2-4cm outward. The extrusion rod 6 can leave some slack, so that there is space between the sealing gaskets 3 to squeeze inward, so that the compression between the sealing gaskets 3 is tighter and prevents air leakage.

[0033] The L-shaped compression rod 6 is arranged in the opposite direction. The compression rod 6 is located at the center line of the length direction of the sealing gasket 3. The position of the compression rod 6 allows the compression rod 6 to be evenly compressed and brought together in the middle when subjected to force.

[0034] A gap is provided between the overlapping position of the sealing gasket 3 and the interface 2 of the gas storage tank 1. A reinforcing sealing gasket 5 is provided at the bottom of the sealing gasket 3 to fit the gap. A reinforcing sealing gasket 5 is provided in the inner position between the overlapping positions of the sealing gasket 3. This makes the connection between the sealing gasket 3 and the interface 2 of the gas storage tank 1 tighter and prevents air leakage.

[0035] The cross-sectional shape of the reinforcing sealing gasket 5 is similar to a triangle, with all three sides of the triangle being inwardly concave arcs. The inwardly concave arcs match the shape of the overlapping area between the gas tank 1 interface 2 and the sealing gasket 3. The reinforcing sealing gasket 5 can be perfectly matched with the arcs of the sealing gasket 3 and the gas tank 1 interface 2, so that the reinforcing sealing gasket 5 itself will not exert too much outward squeezing force on the sealing gasket 3, and the connection between the reinforcing sealing gasket 5 and the sealing gasket 3 is tighter.

[0036] The distance between the three sides of the triangle approaches the intersection and becomes infinitely smaller. The end of the intersection is the edge. When the sealing gasket 3 is closed, it infinitely compresses the reinforcing sealing gasket 5. There is no gap between the sealing gasket 3 and the reinforcing sealing gasket 5. The thickness of the reinforcing sealing gasket 5 is the smallest on the outside, which can reduce the gap between the sealing gasket 3 and the interface 2 of the gas tank 1, making the two more compatible.

[0037] The surface of the sealing gasket 3 has upward protrusions, which are 2-4mm higher than the surface of the sealing gasket 3. The protrusions are concentrated around the overlapping part of the sealing gasket 3. The upward protrusions can prevent slippage when the pressure plate 7 squeezes the sealing gasket 3, increase the friction between the sealing gasket 3 and the pressure plate 7, and effectively improve the squeezing force of the pressure plate 7 on the sealing gasket 3.

[0038] The fastening structure includes a pressure plate 7 and bolts and nuts 8. The pressure plate 7 presses against the junction of the sealing gasket 3 overlapping upwards and wrapping around the interface 2 of the gas storage tank 1. Bolt holes are provided at both ends of the pressure plate 7. The pressure plate 7 is fastened by bolts and nuts 8. The number of bolts and nuts 8 is not limited to that shown in the figure. For the sake of firmness, bolts and nuts 8 can be set at the upper and lower positions of the pressure plate 7, so that the pressure plate 7 can exert a squeezing effect on the sealing gasket 3, effectively preventing gaps from appearing between the sealing gasket 3 and the interface 2 of the gas storage tank 1.

[0039] Wrap the sealing gasket 3 around the interface of the gas tank 1, and then squeeze it inward with the extrusion rod 6. Even when the extrusion rod 6 is pressed down, there is still a gap between the sealing gaskets. Place the reinforcing sealing gasket 5 in this gap. The reinforcing sealing gasket 5 is located in the gap between the overlapping part of the sealing gasket 3 and the interface 2 of the gas tank 1. First push the extrusion rod 6, and when the extrusion rod 6 can no longer move, insert the reinforcing sealing gasket 5. This can prevent the reinforcing sealing gasket 5 from shifting when the extrusion rod 6 is pressing. Press the pressure plate 7 on both sides of the sealing gasket 3, and then tighten it with bolts and nuts 8. This can effectively prevent air leakage. When not in use, the bolts and nuts 8 can be loosened. It does not need to be completely removed. It can also be completely removed as needed.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
