Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline pressure testing technology, specifically to a short-time failure pressure testing component. Background Technology
[0002] Pipelines are channels used to transport substances such as liquids, gases, and solid particles. They are an indispensable infrastructure in modern industry and daily life.
[0003] During short-term failure pressure testing, excessive instantaneous pressure can cause the pipeline to burst and separate from the test cap, rushing out of the test area. This can damage the test cap and the high-pressure delivery pipe, and may also cause personal injury, posing a significant safety hazard. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a short-term failure pressure test component, which can solve the technical problem that when pipelines are subjected to short-term failure pressure tests, the instantaneous pressure is too high, which may cause the pipeline and the pressure test cap to burst and separate and rush out of the test area, damaging the pressure test cap and the high-pressure delivery pipe, and potentially causing personal injury, posing a great safety hazard.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A short-term failure pressure test assembly includes a load-bearing plate. A steel plate is provided on one side of the upper end of the load-bearing plate, and a diagonal brace is provided between one side of the steel plate and the load-bearing plate. A U-shaped groove is formed in the middle of the steel plate. Two hexagonal bolts are provided on the other side of the upper end of the load-bearing plate. The two hexagonal bolts are symmetrically distributed around the U-shaped groove. The same pressure adjusting plate is connected to the two hexagonal bolts. Two limit nuts are provided above the pressure adjusting plate, and the two limit nuts are respectively connected to the two hexagonal bolts.
[0007] Preferably, the steel plate and hexagonal bolts are both welded to the load-bearing plate, and one end of the diagonal brace is welded to the steel plate and the other end is welded to the load-bearing plate.
[0008] Preferably, the load-bearing plate is connected to the ground by bolts.
[0009] Preferably, the hexagonal bolt is made of alloy steel.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During the pressure test, the pressure test cap is placed between two hexagonal bolts and placed on top of the steel plate. After the high-pressure delivery pipe passes through the U-shaped groove on the steel plate, it is fastened to the pressure test cap. Then, the pressure regulating plate is used to press the pressure test cap to prevent the instantaneous pressure generated by the burst test machine from being too large, causing the pipeline and the pressure test cap to burst and separate and rush out of the test area. This protects the pressure test cap and the high-pressure delivery pipe from impact damage, and also avoids personal injury to the operators, thus better ensuring the quality of the product. Attached Figure Description
[0011] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this utility model. For those skilled in the art, other drawings can be obtained based on these drawings.

[0015] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example
[0016] like Figure 1 As shown, this utility model discloses a short-term failure pressure test assembly, including a load-bearing plate 1 with a thickness of 25mm and a size of 2000mm*2000mm. The load-bearing plate 1 is connected to the ground by bolts. A steel plate 2 is provided on one side of the upper end of the load-bearing plate 1. The steel plate 2 is made of impact-resistant and wear-resistant steel plate with a thickness of 25mm. A diagonal brace 3 is provided between one side of the steel plate 2 and the load-bearing plate 1. A U-shaped groove 4 is opened in the middle of the steel plate 2. Two hexagonal bolts 5 are provided on the other side of the upper end of the load-bearing plate 1. The specifications of the hexagonal bolts 5 are M36*300, grade 12.9, and the material is alloy steel. The two hexagonal bolts 5 are symmetrically distributed with the U-shaped groove 4 as the center. The same pressure adjusting plate 6 is connected to the two hexagonal bolts 5. Two limit nuts 7 are provided above the pressure adjusting plate 6. The two limit nuts 7 are threadedly connected to the two hexagonal bolts 5 respectively.
[0017] Furthermore, in this embodiment, the steel plate 2 and the hexagonal bolts 5 are both welded to the load-bearing plate 1, and one end of the diagonal brace 3 is welded to the steel plate 2 and the other end is welded to the load-bearing plate 1, which helps to increase the rigidity of the entire device.
[0018] During the pressure test, the pressure test cap is placed between two hexagonal bolts 5 and placed on top of the steel plate 2. The high-pressure delivery pipe passes through the U-shaped groove 4 on the steel plate 2 and is then tightened with the pressure test cap. The pressure regulating plate 6 is then used to press the pressure test cap to prevent the instantaneous pressure generated by the burst test machine from being too large, which could cause the pipeline and the pressure test cap to burst and separate and rush out of the test area. This protects the pressure test cap and the high-pressure delivery pipe from impact damage and also avoids personal injury to the operators, thus better ensuring the quality of the product.
[0019] 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 application concept of the present utility model, should be included within the protection scope of the present utility model.
