Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment maintenance technology, and in particular to a pipeline protection component used for calibrating pressure gauges in power plants. Background Technology
[0002] In the daily operation and maintenance of power plants, regular calibration of pressure measuring instruments (such as pressure gauges and pressure sensors) is an essential step to ensure their accuracy. Traditionally, pressure gauges and other instruments are removed from the pressure pipelines for calibration without protecting the pipe openings. However, this process carries potential risks. After disassembly, the pipe openings may not be effectively sealed, allowing foreign objects (such as dust, moisture, and metal shavings) to enter the pipeline, affecting the cleanliness of the pipeline system and the measurement accuracy of subsequent instrument installations. This could even lead to equipment damage or safety hazards. Furthermore, the threaded sections connecting the pipe openings to the instruments are not protected, making them susceptible to impact damage during maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a pipeline protection component for use during the calibration of pressure gauges in power plants. By fitting the connecting part of the tubular structure onto the outside of the pipeline, the main body can wrap around the pipe opening and the threaded section at the pipe opening, thus completing the shielding of the pipe opening and the protection of the threaded section. To achieve the above technical features, this utility model achieves its purpose as follows:
[0004] A pipeline protection component used for calibrating pressure gauges in power plants includes a main body, the main body including an end cap and a connecting part disposed on one side of the end cap;
[0005] The connecting part is used to fit onto the outside of the pipe so that the main body can shield and protect the pipe opening and the threaded section at the pipe opening.
[0006] The connecting part is made of a non-metallic elastic material, and the inner diameter A of the connecting part is smaller than the outer diameter B of the pipe.
[0007] The main body is made of rubber.
[0008] The main body also includes a pleated telescopic part, which is disposed between the end cap and the connecting part.
[0009] The end of the connecting part away from the telescopic part is provided with a guide cone surface.
[0010] The main body is equipped with handles.
[0011] There are two handles, which are symmetrically distributed on the outside of the connecting part.
[0012] The main body is equipped with a label.
[0013] The pipeline protection component provided in this embodiment includes a main body, which includes an end cap and a connecting part disposed on one side of the end cap. During operation and maintenance, after the instruments on the pipeline are disassembled, the installation of this component is completed by fitting the tubular connecting part onto the outside of the pipeline. This achieves the purpose of the main body wrapping around the pipe opening and the threaded section at the pipe opening, thus shielding the pipe opening and protecting the threaded section. An expansion joint is also provided between the end cap and the connecting part. Through the pleated expansion joint, the overall length of this component can be extended under external tension to wrap threaded sections of different lengths on different pipelines, making the application more convenient and flexible.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0022] To achieve the above-mentioned technical features, the purpose of this utility model is as follows:
[0023] See appendix Figure 1-4A pipeline protection component for calibrating pressure gauges in power plants includes a main body 1. The main body 1 includes an end cap 1a and a connecting part 1b disposed on one side of the end cap 1a. During operation and maintenance, after the instrument on the pipeline 4 is disassembled, the installation of this application can be completed by fitting the connecting part of the tubular structure onto the outside of the pipeline 4. This achieves the purpose of the main body 1 wrapping the pipe opening of the pipeline 4 and the threaded section 4a at the pipe opening of the pipeline 4, thus completing the shielding of the pipe opening of the pipeline 4 and the protection of the threaded section 4a.
[0024] Furthermore, the connecting part 1b is made of a non-metallic elastic material, and the inner diameter A of the connecting part 1b is smaller than the outer diameter B of the pipe 4. Through the above-described structure of the connecting part 1b, during operation, the connecting part 1b is clamped to the outside of the pipe 4 under its own elastic force. This achieves both the installation and fixation of the main body 1 and a sealing connection, isolating the inside of the pipe from the outside environment to prevent external moisture and dust from entering the pipe. At the same time, this connection method is simple and convenient to install and disassemble.
[0025] Furthermore, the main body 1 is made of rubber. The choice of rubber material ensures that it maintains a good sealing effect even under extreme environments or pressures. At the same time, the elastic restoring force sealing method of the pipe opening achieves a stable seal without the need for additional complex sealing structures, which is simple and efficient, ensuring that foreign objects cannot easily enter the pressure pipeline from the pipe opening. While utilizing the elasticity of rubber to achieve installation, fixation, and sealing, this application also possesses properties such as oil resistance, corrosion resistance, and wear resistance.
[0026] In one embodiment, the main body 1 further includes a pleated telescopic part 1c, which is disposed between the end cap 1a and the connecting part 1b. By making the rubber into a pleated telescopic part 1c, the overall length of the application can be extended under external tension to wrap threaded sections of different lengths on different pipes, making the application more convenient and flexible. It should be noted that by reasonably designing the wall thickness t of the connecting part 1b, the internal tension of the telescopic part 1c during operation can be made less than the frictional force of the connecting part 1b when clamping the pipe, thus ensuring that the telescopic part 1c will not retract after stretching.
[0027] Furthermore, the end of the connecting part 1b away from the telescopic part 1c is provided with a guide cone surface 1d to facilitate the installation of a guide.
[0028] As one implementation method, in this embodiment, the main body 1 is provided with a handle 2 to facilitate the assembly and disassembly of this application.
[0029] Furthermore, there are two handles 2, which are symmetrically distributed on the outside of the connecting part 1b. In this application, force is applied to both handles at the same time during disassembly and assembly, so that they are subjected to symmetrical force and the force distribution is more reasonable.
[0030] As one implementation method, in this embodiment, the main body 1 is provided with a label 3, which can quickly and effectively mark the location and name of the pressure gauge, indirectly improving work efficiency.
