Description

A support structure for a flange-type cryogenic valve Technical Field

[0001] This utility model belongs to the field of petrochemicals and relates to a pipeline support structure, specifically, a support structure for a flange-type cryogenic valve. Background Technology

[0002] Pipe supports are an important component of piping systems, serving functions such as bearing pipe loads, limiting pipe displacement, and controlling pipe vibration. For flanged cryogenic valves, when pipe supports are installed on the straight pipe sections at both ends of the valve, if the valve weight exceeds the pipe stiffness value, excessive deflection at the valve will cause valve sagging, potentially leading to flange leakage or weld cracking over time. In such cases, appropriate support structures need to be installed at the valve.

[0003] The valve's insulation layer uses low-temperature resistant materials, typically polyurethane foam or foam glass. These materials offer good insulation, but due to their low compressive strength, they cannot withstand excessive weight and therefore cannot be used as part of the valve body's support structure.

[0004] The rigid support structure supporting the valve acts directly on the external support, which will create a cold bridge, transferring the low temperature of the medium to the outside of the insulation layer and causing energy loss. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a support structure for a flange-type cryogenic valve, which overcomes the defects of the prior art and prevents excessive deflection at the valve, damage to the valve's insulation layer, and the formation of cold bridges.

[0006] This utility model provides a support structure for a flange-type cryogenic valve. The support structure includes a valve body support assembly and an insulation assembly, which are connected by a connecting assembly to achieve the support function. The valve body support assembly includes a clamp and a support frame, and the insulation assembly includes a rigid insulation block and a base plate. The rigid insulation block can support the weight of the valve and block the heat conduction between the valve body support structure and the external support body, thus preventing cold bridges.

[0007] As an improvement, the valve body support assembly further includes clamp bolts and clamp nuts, which are used to tighten the clamp so that the clamp is tightly connected to the valve flange. The support frame is supported below the clamp and welded to the clamp to achieve synchronous movement between the support frame and the valve.

[0008] As a further improvement, the connection assembly includes a bolt and a nut. One end of the bolt is welded to the base plate, and the other end passes through the rigid insulation block and the support frame and is tightened with a nut to achieve the connection between the valve body support assembly and the insulation assembly.

[0009] As a further improvement, the height H of the support frame should be greater than or equal to the thickness of the valve's insulation structure.

[0010] As a further improvement, a guide or thrust member is welded to the bottom surface of the base plate to achieve the guiding or limiting function of the valve support.

[0011] As a further improvement, guide members and thrust members are welded to the bottom surface of the base plate, which can simultaneously achieve the guiding and limiting functions of the valve support.

[0012] As a further improvement, the width of the clamp should be the same as the thickness of the corresponding flange.

[0013] This utility model has the following beneficial effects:

[0014] 1) The supporting function of this support structure is achieved through rigid components and hard insulation blocks, thereby effectively supporting the valve body with cold insulation and avoiding excessive deflection at the valve due to excessive weight of the valve body.

[0015] 2) This support structure can prevent the generation of cold bridges and block the transfer of the cold energy of the medium to the external support through the support components;

[0016] 3) The base plate of this support structure can achieve the limiting function of the support by combining with guide components or thrust components. The structure is reasonably designed, the performance is stable and reliable, and the installation is convenient. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] As shown in Figures 1 and 2, this utility model provides a support structure for a flange-type cryogenic valve, including a valve body support assembly and an insulation assembly. The valve body support assembly and the insulation assembly are connected by a connecting assembly to achieve the support function. The valve body support assembly includes a clamp 1 and a support frame 4. The insulation assembly includes a rigid insulation block 7 and a base plate 8. The rigid insulation block 7 can support the weight of the valve and block the heat conduction between the valve body support structure and the external support body, thus preventing cold bridges.

[0022] The valve body support assembly also includes clamp bolts 2 and clamp nuts 3. The clamp bolts 2 and clamp nuts 3 are used to fasten clamp 1 so that clamp 1 is tightly connected to valve flange. The support frame 4 is supported below clamp 1 and welded to clamp 1 to realize synchronous movement of support frame 4 and valve.

[0023] Clamp 1, using clamp bolts 2 and clamp nuts 3, tightly secures the flanges on both sides of the flange-type cryogenic valve. The width of clamp 1 should be the same as the thickness of the pair of flanges. After clamp 1 is tightened, two sets of support frames 4 are placed parallel to each other below the two sets of clamps and welded to the clamps. The support frames 4 are in the shape of an inverted "door," and their height H should be equivalent to the insulation thickness of the valve, meaning that after the valve is insulated, there should be no exposed parts of the support frames 4.

[0024] The connecting assembly includes bolts and nuts. One end of the bolt 5 is welded to the base plate 8. After the bolt 5 passes through the insulation block 7 and the support frame 4, it is tightened with nuts 6, thereby connecting the valve body support assembly and the insulation assembly.

[0025] The strength of the support frame 4 and the type of steel used should match the weight of the valve. The lower part of the support frame 4 is provided with a horizontal support surface for tightening bolts 5 and nuts 6 when connecting the valve body support assembly and the insulation assembly.

[0026] During project implementation, the construction sequence should be as follows: valve insulation should be carried out after the flange-type cryogenic valve support structure is installed on site.

[0027] The bottom plate has a welded guide component, which can provide a guiding function for supporting the cryogenic valve.

[0028] A thrust stop component is welded under the base plate 8 to provide thrust stop support for the cryogenic valve.

[0029] The bottom plate 8 is welded with guide components and thrust components, which can realize the limiting function of supporting the low temperature valve.

Any changes or modifications made by those skilled in the art using the above content without departing from the scope of the technical solution of this utility model should be considered equivalent examples of equivalent changes. Any equivalent changes made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
