Description

Technical Field

[0001] The utility model relates to the technical field of elbow brackets, in particular to an air safety valve pipeline bracket. Background Art

[0002] In the pipeline design of the electric power, chemical, petroleum, metallurgy and other industries, pressure pipelines must be equipped with safety valves. When overpressure occurs, the safety valve will automatically open to release the pressure, thereby protecting the safety of the pressure pipeline. At present, for the safety valve vent line of the pipeline with a nominal diameter ≥250, its load-bearing bracket is difficult to set up when it is installed in the air. It is necessary to consider using the original pipeline for support and design a special support bracket.

[0003] The utility model with publication number CN204785066U discloses a novel safety valve valve pipe elbow bracket, including a pipeline, a container, an elbow bracket body, bolts, nuts and a support. A 90-degree elbow is provided at the bottom of the pipeline and is connected to the safety valve outlet. A support is provided below the curved part of the pipeline. The bottom of the support is welded to the wall of the container, and a hole is opened in the top steel plate of the support and welded to the nut. The bolt is screwed into the nut, and the head of the bolt presses against the bottom plate of the elbow bracket body. The top of the elbow bracket body supports the curved part of the pipeline.

[0004] Affected by factors such as the pressure inside the pipeline, changes in medium flow and external impact force, pressure pipelines are prone to axial displacement or radial displacement. These displacements usually occur in elbows, brackets, supports, variable diameter coefficient surfaces and angle changes, which can easily cause pipeline deformation, brittle fracture of pipe bridges and cracks.

DETAILED DESCRIPTION

[0042] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figure 1-5 As shown, an air safety valve pipeline support of the utility model comprises a base 1, a supporting component 2, a first supporting pipe 3 and a tightening component 4.

[0044] Among them, one end of the base 1 is threadedly connected to the supporting component 2, and the other end is used to be fixedly connected to the pipeline 5. The pipeline 5 is the original pressure pipeline in the safety valve vent line layout area. The pressure pipeline is laid horizontally. When installing the base 1, the base 1 is vertically fixed to the top of the pipeline 5 by welding.

[0045] The first support tube 3 is arranged vertically, and one end of the tightening component 4 vertically penetrates the first support tube 3 and is screwed. The upper end of the first support tube 3 is used to fix the connection elbow 6, which is the elbow part of the safety valve. During installation, the upper end of the first support tube 3 is welded to the bottom of the elbow 6, and then the support component 2 and the tightening component 4 are screwed so that the adjacent ends of the support component 2 and the tightening component 4 abut against each other to achieve support, which is used for vertical limitation of the elbow 6. To facilitate the connection with the elbow 6, the upper end of the first support tube 3 is wedge-shaped, which is convenient for matching with the bending part of the elbow 6 and convenient for welding.

[0046] During the operation of the pressure pipeline, affected by factors such as the pressure in the pressure pipeline, changes in medium flow and external impact force, the elbow 6 will not only receive vertical impact force, but also lateral impact force. Therefore, in order to achieve lateral limitation, a limiting groove 401 is set at the bottom end of the tightening component 4, and the opening of the limiting groove 401 faces downward, the bottom of the limiting groove 401 and the top of the supporting component 2 are abutted against each other, and the position of the supporting component 2 is limited by the limiting groove 401 to achieve lateral limitation, and then the vertical limitation is cooperated to achieve protection of the pipeline. Specifically, the limiting groove 401 is set to a circular shape, and the inner diameter of the limiting groove 401 is greater than or equal to the outer diameter of the top of the supporting component 2, so that the top of the supporting component 2 can be smoothly placed in the limiting groove 401.

[0047] In the above structure, the tightening component 4 includes a threaded rod 41 and a groove seat 42, wherein one end of the threaded rod 41 is threadedly engaged with the first support tube 3, and the other end is fixedly connected to the groove seat 42, and the limiting groove 401 is arranged on the end of the groove seat 42 away from the threaded rod 41. The threaded rod 41 can be screwed through the groove seat 42 to adjust the height of the threaded rod 41. For the convenience of screwing, the side of the groove seat 42 is provided with an anti-slip protrusion, specifically, as Figure 4 As shown, the groove seat 42 is in the shape of a circular plate, the anti-skid protrusion is in the shape of a hemisphere, and there are a plurality of anti-skid protrusions in a circular array on the side surface of the groove seat 42 .

[0048] The first support tube 3 is an internally threaded sleeve. Specifically, the first support tube 3 is made of a seamless steel tube, and a first internal thread 301 is provided on the inner wall thereof. The first internal thread 301 is meshed with the threaded rod 41 .

[0049] The base 1 includes a connecting plate 11 and a second supporting tube 12, wherein one end of the connecting plate 11 and the pipeline 5 are fixedly connected by welding, and the other end and one end of the second supporting tube 12 are also fixedly connected by welding. The second supporting tube 12 is made of a seamless steel pipe, and a second internal thread 101 is provided on its inner surface. One end of the supporting component 2 is meshed with the second internal thread 101, and the height of the supporting component 2 is adjusted by meshing. When used for the aerial installation of the pipeline safety valve venting line, the tightening component 4 and the supporting component 2 are screwed at the same time, so that the tightening component 4 and the supporting component 2 can be quickly abutted against each other, thereby improving the installation efficiency.

[0050] In order to improve the connection effect between the connecting plate 11 and the pipeline 5, the connecting plate 11 is an arc-shaped plate, the inner arc surface of the arc-shaped plate is fixedly connected to the side of the pipeline 5, and the outer arc surface of the arc-shaped plate is fixedly connected to one end of the second support tube 12. The arc-shaped connecting plate 11 and the side of the pipeline 5 have a good fit. After the two are fitted, the connecting plate 11 and the pipeline 5 are fixedly connected by welding.

[0051] The applications of the air safety valve pipe support include indoor and outdoor applications. When used outdoors, it will be impacted by rain and wind and sand. In order to prevent water accumulation in the second support tube 12 and prevent the support component 2 from rusting and being damaged, a drainage hole 102 is provided on the side of the second support tube 12 near one end of the connecting plate 11 for draining the water in the second support tube 12, making the air safety valve pipe support suitable for outdoor applications. At the same time, the opening direction of the limiting groove 401 also prevents debris from falling into the limiting groove 401 and makes it difficult for water to accumulate, making it difficult for the top of the support component 2 to be rusted and damaged, further improving the ability of the air safety valve pipe support to adapt to the outdoor environment and making it suitable for outdoor use.

[0052] In the above structure, the support component 2 includes a screw portion 21 and a screwing portion 22, wherein one end of the screw portion 21 is fixedly connected to the screwing portion 22, and the other end is meshed with the second internal thread 101, the screwing portion 22 is prismatic, and one end of the screwing portion 22 away from the screw portion 21 abuts against the bottom of the limiting groove 401. When used for support, the screwing portion 22 is rotated to rotate the screw portion 21, and the screw portion 21 achieves height displacement by meshing with the second internal thread 101. In addition, in the above structure, the support component 2 can also adopt a traditional hexagonal bolt.

[0053] The use method of the utility model of an air safety valve pipeline support is as follows:

[0054] When the air safety valve pipe support is used for the air installation of the pipeline safety valve vent line with a nominal diameter ≥250, first a support component 2 is threadedly connected to the second support tube 12, and then the connecting plate 11 is welded to the top of the pipeline 5, and a tightening component 4 is threadedly connected to the first support tube 3, and the first support tube 3 with the tightening component 4 is moved to the top of the support component 2 and welded to the bottom of the elbow 6. After welding, the support component 2 and the tightening component 4 are screwed at the same time so that the top end of the support component 2 is abutted against the bottom of the limiting groove 401, and the installation of the air safety valve pipe support is completed.
