Technical Field

[0001] The utility model relates to the technical field of steam turbine cooling water systems, in particular to a pipeline that is convenient for observing the blockage condition of a pressure-taking pipeline. Background Technique

[0002] In a steam turbine cooling water system, a pressure-taking pipeline is used to monitor and control the pressure of cooling water to ensure the normal operation of the system. A circulating cooling water system is a common cooling medium system in industrial production, mainly used to take away the heat of production equipment and recycle it to improve the utilization rate of water and save water resources.

[0003] At present, the circulating cooling water of domestic thermal power units is mostly reclaimed water in cities. However, there are many impurities in the reclaimed water, and the sampling pipelines for measuring the pressure and flow of cooling water are very narrow, so it is very easy to cause blockage of the pressure-taking pipeline. Therefore, technical personnel in this field have provided a pipeline that is convenient for observing the blockage condition of the pressure-taking pipeline to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a pipeline that is convenient for observing the blockage condition of a pressure-taking pipeline.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A pipeline that is convenient for observing the blockage condition of a pressure-taking pipeline includes a main pipeline. At a position on one side close to the center of the upper end surface of the main pipeline, a sampling pipeline is provided. At a position on the other side close to the center of the upper end surface of the main pipeline, an outlet pipeline is provided. A flow pipeline is provided on one side wall of the sampling pipeline and one side wall of the outlet pipeline at the upper end of the main pipeline. At a position on one side close to the center of the upper end surface of the flow pipeline, a sight glass is provided.

One end of the manual rod penetrates through the upper end surface of the flow pipeline and extends into the flow pipeline, and a ball valve is fixedly connected to the end.

[0007] For the pipeline that is convenient for observing the blockage condition of a pressure-taking pipeline, the main pipeline, the sampling pipeline, the outlet pipeline and the flow pipeline are all made of stainless steel.

[0008] For the pipeline that is convenient for observing the blockage condition of a pressure-taking pipeline, the main pipeline, the sampling pipeline, the outlet pipeline and the flow pipeline are all fixedly connected.

[0011] 1. In the pipeline facilitating the observation of the blockage condition of the pressure-taking pipeline of the present utility model, the impeller water flow is passed through the sight glass, enabling the user to directly observe the rotation of the impeller water flow through the sight glass, thereby quickly determining whether the pressure-taking pipeline is blocked. When the pipeline is flowing normally, the rotation of the impeller water flow is obvious. If a blockage occurs, the rotation of the impeller water flow slows down or stops, providing the user with a convenient and efficient way to observe the blockage condition, and greatly improving the efficiency of pipeline maintenance and fault troubleshooting.

[0012] 2. The present utility model is made of stainless steel, which has good corrosion resistance, strength and stability, can adapt to various complex working environments, and prolongs the service life of the pipeline. The stainless steel material is not easily corroded and damaged during long-term use, reducing the risk of leakage and failure caused by material aging or corrosion, and improving the reliability and safety of the pipeline system.

[0013] 3. The present utility model can display the pressure value in the flowing pipeline in real time through the pressure measurement instrument, enabling the user to conveniently read the pressure data and timely understand the operating state of the pipeline system. By monitoring the pressure data, potential problems such as abnormal increase or decrease in pressure can be detected in advance, so as to take corresponding measures for adjustment and maintenance.

[0019] Refer to Figures 1-4, an embodiment provided by the present utility model: A pipeline facilitating the observation of the blockage condition of the pressure-taking pipeline, including a main pipeline 1. At a position on one side near the center of the upper end surface of the main pipeline 1, a sampling pipeline 2 is provided. At a position on the other side near the center of the upper end surface of the main pipeline 1, an outlet pipeline 6 is provided. A flow pipeline 10 is provided on one side wall of the sampling pipeline 2 at the upper end of the main pipeline 1 and one side wall of the outlet pipeline 6. At a position on one side near the center of the upper end surface of the flow pipeline 10, a sight glass 3 is provided. Inside the flow pipeline 10 below the sight glass 3, an impeller water flow 7 is provided. At the center of the upper end surface of the flow pipeline 10, a pressure measuring instrument 4 is provided. At a position on the other side near the center of the upper end surface of the flow pipeline 10, a manual rod 5 is provided. One end of the manual rod 5 penetrates through the upper end surface of the flow pipeline 10 and extends into the flow pipeline 10, and the end is fixedly connected with a ball valve 8. When it is necessary to test whether there is a foreign object blockage in the sampling pipeline 2, by rotating the manual rod 5, the ball valve 8 is driven to rotate. When the ball valve 8 is in the open state, the through hole 9 allows the fluid to pass through, realizing the connection of the pipeline. At this time, the measured medium flows back to the main pipeline 1 from the outlet pipeline 6 by virtue of the static pressure, and it is judged whether there is a blockage by observing through the sight glass 3. After the test is completed, by rotating the manual rod 5, when the ball valve 8 is closed, the through hole 9 is blocked, preventing the fluid from flowing, so as to ensure the stability of the measurement.

[0020] Through the sight glass and the impeller water flow, the user can directly observe the rotation condition of the impeller water flow through the sight glass, so as to quickly judge whether the pressure-taking pipeline is blocked. When the pipeline is flowing normally, the impeller water flow rotates significantly. If there is a blockage, the rotation of the impeller water flow slows down or stops, providing a convenient and efficient way for the user to observe the blockage condition, greatly improving the efficiency of pipeline maintenance and fault troubleshooting. The stainless steel material has good corrosion resistance, strength and stability, can adapt to various complex working environments, and prolongs the service life of the pipeline. The stainless steel material is not easily corroded and damaged during long-term use, reducing the risk of leakage and failure caused by material aging or corrosion, and improving the reliability and safety of the pipeline system. Through the pressure measuring instrument, the pressure value inside the flow pipeline can be displayed in real time, enabling the user to conveniently read the pressure data and timely understand the operating state of the pipeline system. By monitoring the pressure data, potential problems such as abnormal increase or decrease of pressure can be detected in advance, so as to take corresponding measures for adjustment and maintenance.

[0021] The main pipeline 1, the sampling pipeline 2, the outlet pipeline 6 and the flow pipeline 10 are all made of stainless steel. The stainless steel material has good corrosion resistance, strength and stability, and can maintain the structural integrity and performance stability of the pipeline in various environments. The main pipeline 1, the sampling pipeline 2, the outlet pipeline 6 and the flow pipeline 10 are all fixedly connected. The fixed connection ensures the overall stability of the pipeline system, reduces the risk of leakage and failure caused by loose connection, and will not loosen or fall off due to the flow of fluid or external factors. A through hole 9 is provided at the center of one side wall of the ball valve 8. When the ball valve 8 is in the open state, the through hole 9 allows fluid to pass through, realizing the connection of the pipeline. When the ball valve 8 is closed, the through hole 9 is blocked to prevent fluid from flowing. A display is provided at the center of the front end face of the pressure measuring instrument 4. The pressure measuring instrument 4 measures the pressure in the flow pipeline 10 through a sensor and displays the pressure value on the display, facilitating the user to read the pressure data in real time.

[0022] Working principle: When it is necessary to test whether there is foreign matter blockage in the sampling pipeline 2, by rotating the manual rod 5, the ball valve 8 is driven to rotate. When the ball valve 8 is in the open state, the through hole 9 allows fluid to pass through, realizing the connection of the pipeline. At this time, the measured medium flows back from the outlet pipeline 6 to the main pipeline 1 by static pressure, and it is judged whether there is blockage by observing through the sight glass 3. After the test, by rotating the manual rod 5, when the ball valve 8 is closed, the through hole 9 is blocked to prevent fluid from flowing, so as to ensure the stability of the measurement.
