To ensure the safe operation of special equipment, the state has strict regulations on the production, use, and inspection and testing of various types of special equipment, and implements supervision throughout the entire process. Pressure testing will be carried out during the inspection process.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown:

[0024] An intelligent pressure testing device for pressure-bearing special equipment comprises a connecting pipe 1.

[0025] In this embodiment: the existing announcement number: CN218098582U discloses an intelligent pressure test device for pressure-bearing special equipment; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "during the pressure test process, it is difficult to ensure that the connection between the pressure test instrument and the equipment is sufficiently stable. Then, under high pressure, the connection between the two may become loose, thereby affecting the experimental data." In terms of combined use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve the above problems, a reinforcement pipe 2 and a mounting frame 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a reinforcing tube 2, a mounting bracket 3, a pressure tank 4, a piston 5, a connecting rod 6, a transmission rod 7 and a fixing bar 8 arranged on one side of the connecting tube 1, one side of the connecting tube 1 is threadedly connected to the reinforcing tube 2, and the inner surface of the reinforcing tube 2 is also fixedly mounted with a mounting bracket 3, and one side of the mounting bracket 3 is also fixedly mounted with a pressure tank 4 that is slidingly connected to the piston 5, the side surface of the piston 5 away from the mounting bracket 3 is also fixedly connected to the connecting rod 6, and the connecting rod 6 is also rotationally connected to one end of the transmission rod 7, and the other end of the transmission rod 7 is also rotationally connected to one end of the fixing bar 8, and the fixing bar 8 is slidingly connected to the connecting tube 1 and the reinforcing tube 2.

[0029] In this embodiment: when the pressure test is carried out, the connecting pipe 1 and the reinforcement pipe 2 are connected by threads. At this time, the internal pressure of the connecting pipe 1 and the reinforcement pipe 2 is in a normal state, the piston 5 is located on the outside of the pressure tank 4, and the fixing bar 8 is also located inside the reinforcement pipe 2. When the pressure between the connecting pipe 1 and the reinforcement pipe 2 gradually increases, the pressure in the internal space of the pressure tank 4 also increases accordingly, and the space inside the pressure tank 4 will be compressed. At this time, the piston 5 will slide between the pressure tank 4 and drive the connecting rod 6 to move synchronously. The transmission rod 7 connected to the surface of the connecting rod 6 will gradually tend from an inclined state to a state perpendicular to the connecting rod 6, and the fixing bar 8 will also slide with the reinforcement pipe 2 and be inserted into the hole opened in the connecting pipe 1. At this time, the connecting pipe 1 and the reinforcement pipe 2 remain at the current angle and cannot rotate further, thereby maintaining the tightness of the connection between the two.

[0030] Going further:

[0031] In an optional embodiment, rectangular through holes are symmetrically opened on the surface of the reinforcement tube 2 .

[0032] In this embodiment, the rectangular through holes symmetrically opened on the surface of the reinforcing tube 2 allow the fixing bar 8 to pass through the reinforcing tube 2 and the connecting tube 1 to form a connection, thereby preventing the connecting tube 1 and the reinforcing tube 2 from loosening during the pressure test.

[0033] Going further:

[0034] In an optional embodiment, the mounting frame 3 is hollow in shape, and through holes are opened at equal angles on the surface of the mounting frame 3 .

[0035] In this embodiment, the hollow-shaped mounting frame 3 can stably place the pressure tank 4 inside the reinforcement pipe 2 without affecting the normal pressure test work.

[0036] Going further:

[0037] In an optional embodiment, the pressure tank 4 is in the shape of a hollow cylinder.

[0038] In this embodiment, the hollow pressure tank 4 can form a stable closed space inside when blocked by the piston 5, thereby ensuring that the compression work between the piston 5 and the pressure tank 4 can be carried out stably.

[0039] Going further:

[0040] In an optional embodiment, the transmission rod 7 and the fixing bar 8 are symmetrically arranged on both sides of the surface of the connecting rod 6 .

[0041] In this embodiment: the transmission rod 7 and the fixing bar 8 symmetrically arranged on both sides of the surface of the connecting rod 6 can drive the transmission rod 7 and the fixing bar 8 on both sides to move simultaneously when the connecting rod 6 moves, and then the connecting pipe 1 and the reinforcement pipe 2 can be connected through the fixing bar 8.

[0042] Going further:

[0043] In an optional embodiment, the fixing strip 8 matches the holes opened on the surfaces of the connecting tube 1 and the reinforcing tube 2 .

[0044] In this embodiment, the movement of the fixing bar 8 can form a stable connection between the connecting pipe 1 and the reinforcement pipe 2, thereby maintaining a good contact relationship between the connecting pipe 1 and the reinforcement pipe 2, so that the pressure test work can be carried out stably.

[0045] The working principle and usage process of the present invention are as follows: when the pressure test is carried out, the connecting pipe 1 and the reinforcement pipe 2 are connected by threads. At this time, the internal pressure of the connecting pipe 1 and the reinforcement pipe 2 is in a normal state, the piston 5 is located on the outside of the pressure tank 4, and the fixing bar 8 is also located inside the reinforcement pipe 2. When the pressure between the connecting pipe 1 and the reinforcement pipe 2 gradually increases, the pressure in the internal space of the pressure tank 4 also increases accordingly, and the space inside the pressure tank 4 will be compressed. At this time, the piston 5 will slide between the pressure tank 4 and drive the connecting rod 6 to move synchronously. The transmission rod 7 connected to the surface of the connecting rod 6 will gradually tend from an inclined state to a state perpendicular to the connecting rod 6, and the fixing bar 8 will also slide with the reinforcement pipe 2 at this time and be inserted into the hole opened in the connecting pipe 1. At this time, the connecting pipe 1 and the reinforcement pipe 2 remain at the current angle and cannot rotate further, thereby maintaining the tightness of the connection between the two.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
