[0014] Compared with the prior art, the utility model provides a precision welded steel pipe with a water pressure resistant structure, which has the following beneficial effects:

[0015] This precision welded steel pipe with a water pressure-resistant structure will cause the first cavity to be squeezed when the water pressure in the steel pipe body suddenly increases. At this time, the first pressure regulating block will enter the positioning groove, thereby expanding the volume inside the steel pipe body, thereby reducing the impact force of the water pressure on the steel pipe body, making it less likely to cause the risk of leakage at the pipe joints and increasing the service life of the steel pipe body.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model is a precision welded steel pipe with a water pressure resistant structure, comprising a steel pipe body 1, a plurality of pressure regulating components are arranged on the inner wall of the steel pipe body 1, the pressure regulating components include a positioning seat 2 and a first pressure regulating block 4, a positioning groove 3 is arranged inside the positioning seat 2, the bottom end of the first pressure regulating block 4 is inserted into the positioning groove 3, and a first cavity 6 is arranged inside the first pressure regulating block 4, and both sides of the first cavity 6 are arc-shaped structures;

[0022] In this structure, the positioning seat 2 and the steel pipe body 1 are an integrated structure. The first pressure regulating block 4 is taken and the rear end of the first pressure regulating block 4 is fixed inside the positioning groove 3 by a designated tool, so that the first pressure regulating block 4 can be installed.

[0023] When the water pressure in the steel pipe body 1 suddenly increases, the first cavity 6 will be squeezed, and the first pressure regulating block 4 will enter the positioning groove 3, thereby expanding the volume inside the steel pipe body 1, thereby reducing the impact force of the water pressure on the steel pipe body 1, and is less likely to cause the risk of leakage at the pipe joints. It can also increase the service life of the steel pipe body 1. Since the two sides of the first cavity 6 are arc-shaped structures, the first pressure regulating block 4 can be smoother when squeezed.

[0024] In this structure, the first voltage regulating block 4 is bonded inside the positioning groove 3, and the bonding method has the advantage of convenient assembly.

[0025] In the present structure, a plurality of second pressure regulating blocks are arranged on the first pressure regulating block 4, and a second cavity 7 is arranged inside the second pressure regulating block. The water pressure in the steel pipe body 1 will also compress the second cavity 7, thereby reducing the volume of the second pressure regulating block, further improving the pressure resistance of the steel pipe body 1, and preventing the steel pipe body 1 from being suddenly subjected to the impact force of the water pressure.

[0026] Furthermore, the second pressure regulating block and the first pressure regulating block 4 are both made of rubber. As an important industrial material, rubber has many significant advantages, which are mainly reflected in the following aspects: it has excellent elasticity and resilience, and has good wear resistance and corrosion resistance.

[0027] Furthermore, the sizes of the plurality of first voltage-regulating blocks 4 are the same, the sizes of the plurality of second voltage-regulating blocks are the same, and the second voltage-regulating blocks are spherical structures.
