Description

Technical Field

[0001] This utility model relates to the field of clamp interface technology, specifically a pressure vessel clamp-type interface. Background Technology

[0002] Pressure vessels are widely used in the industrial field, and their connection methods are crucial to the safety and stability of the vessels. Existing pressure vessel interface types include: welded connection, threaded connection, flange connection, and clamp connection. Among them, clamp connection is generally used for small or low-pressure vessels.

[0003] Existing clamp connections are fixed by tightening nuts. However, pressure vessels are subject to mechanical vibration in their working environment during actual use. This vibration can easily cause the nuts to loosen, leading to a loose clamp connection. Therefore, a clamp-type interface for pressure vessels is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure vessel clamping interface in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel clamping interface, including a first T-shaped connector, a second T-shaped connector, a sealing gasket, and a clamp assembly. The sealing gasket is distributed between the first T-shaped connector and the second T-shaped connector, and the clamp assembly is clamped on the outside of the joint of the first T-shaped connector and the second T-shaped connector to fix the joint of the first T-shaped connector and the second T-shaped connector.

[0006] The clamp assembly includes a clamping unit and an anti-loosening unit;

[0007] The locking unit is used to clamp and hold the first T-shaped connector and the second T-shaped connector.

[0008] The anti-loosening unit is used to lock the locking state of the locking unit to prevent the locking unit from becoming loose.

[0009] As a further embodiment of this utility model: the locking unit includes an arc-shaped clamp, a side concave connecting seat, a side T-shaped screw, and a locking nut;

[0010] Two arc-shaped clamps are provided, and one end of the two arc-shaped clamps is rotatably connected. The concave side connecting seat is fixed to the end of the two arc-shaped clamps away from the rotatable end.

[0011] The side T-shaped screw is rotatably connected to the inner side of a side concave connecting seat, and the locking nut is threadedly connected to the outer side of the transverse screw of the side T-shaped screw;

[0012] Two arc-shaped clamps are wrapped around the outside of the joint between the first T-shaped connector and the second T-shaped connector, allowing the transverse screw of the side T-shaped screw to rotate and pass through the other side concave connector. The locking nut is then tightened to press against the side of the other side concave connector, thus achieving the wrapping and clamping of the joint between the first T-shaped connector and the second T-shaped connector.

[0013] As a further improvement of this utility model: the anti-loosening unit includes an L-shaped folded edge, a U-shaped locking rod, a positioning square block, and a compression spring;

[0014] The L-shaped fold is integrally formed at the bottom end of a side concave connecting seat. A vertical part of the U-shaped clamp rod vertically penetrates the L-shaped fold and is slidably connected to the L-shaped fold. The positioning square block is fixed to the top of a vertical part of the U-shaped clamp rod. The compression spring is distributed between the bottom of the positioning square block and the top of the L-shaped fold, and is sleeved on the outside of a vertical part of the U-shaped clamp rod.

[0015] When the two arc-shaped clamps are rotated and fitted onto the outside of the first T-shaped connector and the second T-shaped connector, the other vertical part of the U-shaped clamp rod is attached to the side of the other concave connector, which is used to limit the position of the two concave connectors.

[0016] As a further embodiment of this utility model: two sets of L-shaped folding edge, U-shaped locking rod, positioning square block, compression spring and two side concave connecting seats are provided, and the two sets of L-shaped folding edge, U-shaped locking rod, positioning square block and compression spring are symmetrically distributed vertically, and the two sets of U-shaped locking rod, positioning square block and compression spring are staggered along the horizontal longitudinal direction.

[0017] As a further improvement of this utility model: a through hole is provided on the horizontal part of the L-shaped folded edge for the vertical part of the U-shaped clamp to pass through;

[0018] The top of the concave side connector is provided with a square hole for the positioning square block to pass through, and the positioning square block protrudes from the upper surface of the concave side connector through the square hole in the initial state.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up a clamp assembly with an anti-loosening unit, when the locking nut becomes loose due to vibration, the U-shaped clamp rod can fix the two concave side connecting seats, so that the two concave side connecting seats still maintain a fixed relative position. That is, the arc-shaped clamp maintains a stable clamping state, which further improves the connection stability of the first T-shaped connection and the second T-shaped connection.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 In this embodiment of the present invention, a pressure vessel clamping interface includes a first T-shaped connector 1, a second T-shaped connector 2, a sealing gasket 3, and a clamping assembly 4. The sealing gasket 3 is distributed between the first T-shaped connector 1 and the second T-shaped connector 2, and the clamping assembly 4 is clamped on the outside of the joint of the first T-shaped connector 1 and the second T-shaped connector 2 to fix the joint of the first T-shaped connector 1 and the second T-shaped connector 2.

[0027] Clamp assembly 4 includes a clamping unit and an anti-loosening unit;

[0028] The clamping unit is used to wrap and hold the first T-shaped connector 1 and the second T-shaped connector 2.

[0029] The anti-loosening unit is used to lock the locking state of the locking unit to prevent the locking unit from becoming loose;

[0030] The fastening unit includes an arc-shaped clamp 401, a side concave connecting seat 402, a side T-shaped screw 403, and a locking nut 404;

[0031] Two arc-shaped clamps 401 are provided, and one end of the two arc-shaped clamps 401 is rotatably connected. The concave side connecting seat 402 is fixed to the end of the two arc-shaped clamps 401 away from the rotatable end.

[0032] The side T-screw 403 is rotatably connected to the inner side of a side concave connecting seat 402, and the locking nut 404 is threadedly connected to the outer side of the transverse screw of the side T-screw 403.

[0033] Two arc-shaped clamps 401 are wrapped around the outside of the joint between the first T-shaped connector 1 and the second T-shaped connector 2, so that the transverse screw of the side T-shaped screw 403 rotates through the other side concave connector 402, and the locking nut 404 is tightened to press the side of the other side concave connector 402, thereby achieving the wrapping and clamping of the joint between the first T-shaped connector 1 and the second T-shaped connector 2;

[0034] The anti-loosening unit includes an L-shaped folded edge 405, a U-shaped locking rod 406, a positioning square block 407, and a compression spring 408;

[0035] The L-shaped flange 405 is integrally formed at the bottom end of a side-concave connecting seat 402. A vertical part of the U-shaped clamp 406 extends vertically through the L-shaped flange 405 and is slidably connected to the L-shaped flange 405. The positioning square block 407 is fixed to the top of the vertical part of the U-shaped clamp 406. The compression spring 408 is distributed between the bottom of the positioning square block 407 and the top of the L-shaped flange 405, and is sleeved on the outside of the vertical part of the U-shaped clamp 406.

[0036] When the two arc-shaped clamps 401 are rotated and sleeved on the outside of the first T-shaped connection port 1 and the second T-shaped connection port 2, the other vertical part of the U-shaped clamp 406 is attached to the side of the other concave connection seat 402 to achieve position limiting of the two concave connection seats 402.

[0037] In this embodiment, it should be noted that the straight pipe sections of the first T-shaped connector 1 and the second T-shaped connector 2 are welded and fixed to the pressure vessel and the connecting pipeline, respectively, and are connected.

[0038] When fixing the first T-shaped connector 1 and the second T-shaped connector 2 using the clamp assembly 4, the operation steps are as follows:

[0039] Rotate the two arc-shaped clamps 401 to open them and bring them close to the outside of the joint of the first T-shaped connector 1 and the second T-shaped connector 2. Then rotate the two arc-shaped clamps 401 to bring them closer to each other and finally fit them onto the outside of the joint of the first T-shaped connector 1 and the second T-shaped connector 2.

[0040] Then, pull the corresponding U-shaped locking rod 406 on the side concave connecting seat 402 that is rotatably connected to the side T-shaped screw 403, so that the U-shaped locking rod 406 and the square positioning block 407 move down as a whole. The square positioning block 407 squeezes and compresses the spring 408 to further deform and contract, so that the U-shaped locking rod 406 and the square positioning block 407 release the blockage of the opening of the side concave connecting seat 402, and then the side T-shaped screw 403 can be rotated to approach the other side concave connecting seat 402.

[0041] Then, move the U-shaped locking rod 406 on the other concave side connector 402 upwards, and rotate the transverse screw of the side T-shaped screw 403 to engage with the inside of the other concave side connector 402. Then release the pull on the U-shaped locking rod 406 (it should be noted that at this time, the transverse part of the U-shaped locking rod 406 faces the opening of the concave side connector 402, so that the U-shaped locking rod 406 will not interfere with the mutual approach of the two concave side connectors 402).

[0042] Then, tighten the locking nut 404 so that it approaches the other concave connecting seat 402 along the transverse outer wall of the side T-shaped screw 403, and compresses the other concave connecting seat 402, so that the two concave connecting seats 402 approach each other, and then the two arc-shaped clamps 401 clamp and fix the splice of the first T-shaped connecting port 1 and the second T-shaped connecting port 2.

[0043] When the two arc-shaped clamps 401 are fully clamped, the two U-shaped clamps 406 can be pulled in sequence and rotated horizontally by 90 degrees, so that the lateral part of the U-shaped clamps 406 rotates from being flush with the concave side connecting seat 402 to being perpendicular to each other. Then, the pulling of the U-shaped clamps 406 is released, and the U-shaped clamps 406 are reset under the elastic force of the compression spring 408. The other vertical part of the U-shaped clamps 406 is attached to the side of the other concave side connecting post 402. In this way, the position of the two concave side connecting seats 402 is limited. Thus, when the locking nut 404 becomes loose due to vibration, the two concave side connecting seats 402 still maintain a fixed relative position, that is, the arc-shaped clamps 401 maintain a stable clamping state.

[0044] Please refer to this carefully. Figures 1-3 Two sets of L-shaped folded edges 405, U-shaped locking rods 406, positioning square blocks 407, compression springs 408 and two side concave connecting seats 402 are provided. The two sets of L-shaped folded edges 405, U-shaped locking rods 406, positioning square blocks 407 and compression springs 408 are symmetrically distributed vertically, and the two sets of U-shaped locking rods 406, positioning square blocks 407 and compression springs 408 are staggered along the horizontal longitudinal direction.

[0045] In this embodiment: by using two sets of symmetrically distributed L-shaped folded edges 405, U-shaped locking rods 406, positioning square blocks 407, and compression springs 408, the two sets of U-shaped locking rods 406 are subjected to opposite forces when the clamp assembly 4 is subjected to vibration, thus ensuring the stable locking of the two side concave connecting seats 402.

[0046] The two sets of U-shaped levers 406, the positioning square blocks 407, and the compression springs 408 are staggered along the horizontal longitudinal direction, so that the two sets of U-shaped levers 40 do not interfere with each other.

[0047] Please refer to this carefully. Figure 3 The L-shaped folded edge 405 has a through hole 409 on its horizontal part for the vertical part of the U-shaped clamp 406 to pass through;

[0048] The top of the concave side connector 402 is provided with a square hole 410 for the positioning square block 407 to pass through, and the positioning square block 407 initially protrudes from the upper surface of the concave side connector 402 through the square hole 410.

[0049] In this embodiment: the U-shaped locking rod 406 can be positioned in the direction of the positioning square block 407 by engaging with the square hole 410. In the initial state, the positioning square block 407 protrudes from the upper surface of the side concave connecting seat 402 through the square hole 410. When the positioning square block 407 vibrates up and down due to vibration, the positioning square block 407 can maintain the engagement state with the square hole 410.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
