Description

Technical Field

[0001] This utility model relates to the field of aluminum foil coating production technology, specifically to a sealing structure for a compressed air energy storage tank. Background Technology

[0002] Air is usually stored in a dedicated air tank after compression. However, due to the high internal pressure of the tank, ordinary ball valve-type sealing switches are prone to deformation and gaps due to compression, causing the seals to slowly fail and resulting in internal air leakage, which affects the normal use of the air tank. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a sealing structure for a compressed air energy storage tank, including a storage tank and an outlet pipe. Its features include: an outlet pipe flange, a sealing box, a connecting flange, flange fixing bolts, a flange sealing ring, an outlet pipe of the sealing box, an upper sealing plate, a lower partition plate, a sealing block, an inner threaded seat, an outer threaded seat, a handwheel, a screw, and a locking block; the outlet pipe of the storage tank is provided with an outlet pipe flange at its end; the sealing box has an air inlet hole on the upper side of its left side and an air outlet hole on the lower side of its right side; an upper sealing plate is provided on the upper side of the interior, a lower partition plate is provided on the lower side, a circular hole is provided in the center of the lower partition plate, and a circular hole is provided in the center of the bottom surface. The sealing box has screw holes; the connecting flange is fixedly installed at the air inlet on the left side of the sealing box, and the flange sealing ring is fitted into the air outlet pipe on the protrusion on its left side; the flange fixing bolt passes through the air outlet pipe flange and is fixed to the connecting flange; the air outlet pipe of the sealing box is installed at the air outlet on the right side of the sealing box; the sealing block is fixedly installed on the upper side of the lower partition plate, and a circular air hole is opened in the center; the inner screw seat is installed on the bottom surface inside the sealing box; the outer screw seat is installed in the center of the lower side of the sealing box; the screw is fitted on the inner screw seat and the outer screw seat, and a handwheel is provided at its lower end and a locking block is provided at its top end, which is engaged in the air hole of the sealing block.

[0004] As a preferred technical solution of this utility model, the left side of the connecting flange protrudes to form an annular boss, which is inserted into the air outlet pipe, and a flange sealing ring is installed on the outer wall of the boss to seal the gap between the boss and the air outlet pipe.

[0005] As a preferred embodiment of this utility model, the lower side of the upper sealing plate is tangent to the air inlet on the left side of the sealing box.

[0006] As a preferred embodiment of this utility model, the outer wall of the sealing block is glued and fixed to the sealing box, and the bottom surface is fixed to the lower partition plate with bolts.

[0007] As a preferred embodiment of this utility model, the distance between the lower partition and the bottom surface of the sealing box is not less than 1.5 times the height of the sealing block.

[0008] As a preferred embodiment of this utility model, the top of the card block is arc-shaped, its outer diameter is larger than the diameter of the central air hole of the sealant block, and its height is equal to the height of the sealant block.

[0009] The beneficial effects of this utility model are as follows: This utility model designs an L-shaped circuit, adjusting the straight gas outlet pipe to an L-shape so that the gas pressure on the inner wall of the tank acts on the side of the sealing block, causing it to deform under pressure and fit more closely with the locking block, thus maintaining a good sealing effect for a long time. At the same time, the gas path can be easily opened by controlling the handwheel. Attached Figure Description

Detailed Implementation

[0015] Example 1 like Figures 1 to 3As shown, this utility model discloses a sealing structure for a compressed air energy storage tank, including a storage tank 1 and an outlet pipe 2. Its features include: an outlet pipe flange 3, a sealing box 4, a connecting flange 5, flange fixing bolts 6, a flange sealing ring 7, an outlet pipe 8 of the sealing box, an upper sealing plate 9, a lower partition plate 10, a sealing block 11, an inner threaded seat 12, an outer threaded seat 13, a handwheel 14, a screw 15, and a locking block 16; the outlet pipe 2 of the storage tank 1 is provided with an outlet pipe flange 3 at its end; the sealing box 4 has an air inlet hole on the upper side of its left side and an air outlet hole on the lower side of its right side, an upper sealing plate 9 on its upper interior side, a lower partition plate 10 on its lower interior side, a circular hole in the center of the lower partition plate 10, and a screw hole in the center of its bottom surface; The connecting flange 5 is fixedly installed at the air inlet on the left side of the sealing box 4, and the flange sealing ring 7 is fitted into the air outlet pipe 2 on the protruding left side of the flange 5; the flange fixing bolt 6 passes through the air outlet pipe flange 3 and is fixed to the connecting flange 5; the air outlet pipe 8 of the sealing box is installed at the air outlet on the right side of the sealing box 4; the sealing block 11 is fixedly installed on the upper side of the lower partition plate 10, and a circular air hole is opened in the center of it; the inner thread seat 12 is installed on the bottom surface inside the sealing box 4; the outer thread seat 13 is installed in the center of the lower side of the sealing box 4; the screw 15 is fitted on the inner thread seat 12 and the outer thread seat 13, and a handwheel 14 is provided at its lower end and a locking block 16 is provided at its top end. The locking block 16 is inserted into the air hole of the sealing block 11. The left side of the connecting flange 5 protrudes to form a circular boss, which is inserted into the air outlet pipe 2. The flange sealing ring 7 is installed on the outer wall of the boss to seal the gap between the boss and the air outlet pipe 2, and is locked and fixed by the flange fixing bolts 6. The outer wall of the sealing block 11 is glued and fixed to the sealing box 4, and the bottom is fixed to the lower partition plate 10 with bolts. This allows the gas pressure to act on the upper side of the sealing block 11, avoiding deformation caused by long-term use, which could lead to gaps in the pipeline and leakage.

[0016] The working principle of this utility model is as follows: An outlet flange 3 is installed at the end of the outlet pipe 2 of the gas storage tank 1, and a connecting flange 5 is fitted onto the outlet flange 3. Then, the flange fixing bolts 6 are used to tighten it. When the entire structure is sealed, the locking block 16 engages with the air hole in the sealing block 11. The gas pressure inside the tank acts on the upper side of the sealing block 11, causing deformation that pushes the locking block 16 inward, preventing gaps from forming due to failure. To open the gas path, turn the handwheel 14 to move the locking block 16 downwards. When the locking block 16 exits the sealing block 11, the gas path is unobstructed, and the gas inside the tank is discharged from the outlet pipe 8 of the sealed box. To close the gas path, reverse the handwheel 14 to re-engage the locking block 16 into the sealing block 11.
