Description

Technical Field

[0001] The utility model belongs to the technical field of flange joints, in particular to a flange pipeline joint for a high-pressure valve block. Background Art

[0002] The flange pipe joint for high-pressure valve blocks is a key component used to connect high-pressure valve blocks and pipelines. It is usually made of high-strength metal materials, such as stainless steel or alloy steel. Its structural design includes a flange and a part for connecting the pipeline. The flange is provided with mounting holes, which are tightly fixed to the corresponding parts by bolts. This joint can withstand the impact and pressure of the fluid in a high-pressure environment, ensuring the sealing and stability of the pipeline system.

[0003] In actual use, the existing high-pressure flange pipe joints have exposed the problem of complex connection methods. They are mainly connected by bolts. This connection method increases the cumbersomeness of the operation to a certain extent. Since the connection is completely dependent on bolts, when the device needs to be disassembled, the bolts must be disassembled one by one. This process is not only time-consuming and labor-intensive, but also extremely tests the patience and carefulness of the operator. Each bolt needs to be handled separately and cannot be missed, otherwise it may affect the subsequent disassembly work and may even cause damage to components. Moreover, the method of disassembling the bolts one by one cannot achieve fast and efficient operations. In some work scenarios with more urgent time requirements, this slow disassembly process will undoubtedly greatly reduce work efficiency and delay the entire work progress. Utility Model Content

Moreover, the method of disassembling the bolts one by one cannot achieve fast and efficient operations. In some work scenarios with more urgent time requirements, this slow disassembly process will undoubtedly greatly reduce work efficiency and delay the entire work progress.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a flange pipe joint for a high-pressure valve block, comprising a flange joint and a connecting mechanism and a configuration mechanism arranged on the flange joint;

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model sets a connecting mechanism. When in use, the pull rod is first pulled outward. During this process, the pull rod cooperates with the strip rod and the limit block to compress the spring on its outer wall. In this way, the limit ring on the pull rod can move outward, thereby effectively preventing it from blocking the insertion of the connecting pipe. Then, the sealing gasket on the connecting pipe is inserted into the sealing groove on the flange joint. Through such operation, it can be ensured that the flange joint and the connecting pipe are sealed very firmly, and liquid leakage during use is avoided to a great extent. When the connecting pipe is plugged in, the pull rod is released. At this time, the pull rod will be pushed by the spring to drive the limit ring on it to move inward, effectively limit the flange joint, and then the flange joint and the connecting pipe can be firmly fixed together. Through this setting, the tedious process of installation and disassembly can be reduced, thereby improving its work efficiency.

[0016] (2) The utility model sets up a configuration mechanism, and then pulls the slide bar 1 backward. During this action, the slide bar 1 cooperates with the two rectangular blocks and the limit block 2 to compress the spring 2 on its outer wall, so that the slide bar 1 can drive the semi-circular disk 1 and the semi-circular disk 2 thereon to move to the appropriate position. When moving to the appropriate position, the slide bar 2 is rotated so that the slide bar 2 drives the semi-circular disk 2 to slide in the arc groove on the semi-circular disk 1. Through this series of operations, the connecting pipe can be effectively limited. After the limiting is completed, the slide bar 1 is released. The slide bar 1 will be pushed by the spring 2 to drive the semi-circular disk 2 to apply a pulling force to the connecting pipe. Such a setting helps to further enhance the stability of the connection of the connecting pipe and ensure that it will not loosen during the working process.

When they move to a suitable position, the slide bar 2 39 is rotated so that the slide bar 2 39 drives the semi-circular disk 2 38 to slide in the arc groove 37 on the semi-circular disk 1 36.

Such a setting helps to further enhance the stability of the connection of the connecting pipe 21 and ensure that it will not be loose during the working process. Finally, the two circular blocks 395 are moved closer to each other. During the movement, the two circular blocks 395 will compress the dampers 396 and spring three 397 thereon, so that the limiting rods 394 on the two circular blocks 395 can be inserted into the U-shaped block 392 respectively. After the insertion, the two circular blocks 395 are released, so that the two circular blocks 395 and the limiting rods 394 on the circular blocks 395 can be reset under the push of spring three 397.
