Description

Technical Field

[0001] This utility model relates to the field of safety valve installation technology, and in particular to a safety valve support structure for 90-degree bend positions suitable for scenarios without support points. Background Technology

[0002] In existing technologies, the traditional safety valve support structure relies on the outlet pipe elbow as a fulcrum, requiring ground or structural beam support. It cannot be supported or installed in situations where there is no support point.

[0003] Furthermore, the high recoil force during venting directly impacts the flange bolts connected to the safety valve, causing stress concentration in the bolts, deformation of the flange sealing surface, and the following problems:

[0004] 1. Vibration hazards: Lack of rigid support can easily lead to valve vibration, affecting sealing performance and lifespan;

[0005] 2. Stress concentration: Traditional single-point support may cause local deformation of the pipeline or cracking of the weld.

[0006] Therefore, how to provide a reliable support structure for safety valves in scenarios without support points has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of the above-mentioned defects of the prior art, the present invention provides a support structure for a safety valve in a 90-degree bend position suitable for scenarios without support points, the purpose of which is to provide a reliable support structure for safety valves in scenarios without support points.

[0008] To achieve the above objectives, this utility model discloses a safety valve support structure for a 90-degree bend position applicable to scenarios without support points, including a first pipe and a second pipe connected at a 90-degree angle; the first pipe and the second pipe are respectively connected to the two connecting ends of the safety valve at a 90-degree angle to each other.

[0009] Among them, the sidewalls of the first pipe and the second pipe at a 90-degree angle are each provided with a protective plate whose shape matches the corresponding first pipe or the corresponding second pipe, and are respectively connected to the two ends of a telescopic structure through the channel steel structure set on the corresponding protective plate.

[0010] The retractable structure includes a tensioning sleeve, and a first eye bolt and a second eye bolt respectively disposed at both ends of the tensioning sleeve;

[0011] The tightening and loosening threaded sleeve includes a first part and a second part that are movably connected; a spring is provided between the first part and the second part; the first part is connected to the first eye bolt; the second part is connected to the second eye bolt;

[0012] The hook-shaped ends of the first and second eye bolts are both hooked onto the corresponding channel steel structures, and the threaded ends are fixed to the tightening and loosening sleeves by clamping nuts.

[0013] Preferably, each of the channel steel structures has a bolt at the end away from the corresponding first pipe or the corresponding second pipe, and the hook-shaped end of the corresponding first eye bolt or the corresponding second eye bolt is fixed by the bolt.

[0014] Preferably, each of the channel steel structures is fixed to the corresponding protective plate by welding.

[0015] Preferably, each of the protective plates is fixed to the corresponding first pipe or the corresponding second pipe by welding.

[0016] The beneficial effects of this utility model are:

[0017] This invention is more adaptable and can be installed in scenarios without traditional support points, such as straight pipe sections and high-altitude pipelines.

[0018] This invention provides stronger protection for flange connections, reduces release reaction force, and extends the life of bolts and flanges.

[0019] This utility model has a simple and reliable structure, requires no additional foundation, and is fixed by welding with spring buffer, resulting in low maintenance costs.
