What are the characteristics of commonly used check valves in the power industry?

The commonly used check valve in the power industry is a type of valve used to ensure the normal operation of power equipment and the safety of pipelines. For check valves, their main function is to prevent fluid backflow in the pipeline from causing equipment damage, and to ensure that the valve does not experience water hammer, while also reducing noise and vibration in the pipeline system. The main characteristics of check valves in the power industry are as follows.

1. Simple structure, easy to maintain

Compared to other valves, check valves have a simpler structure and are therefore easier to maintain. Generally speaking, the structure of a check valve only includes several parts such as the valve body, valve cover, valve disc, and spring, all of which are more convenient to maintain. In addition, the sealing performance of the check valve is also relatively good, making it easier to clean.

2. Strong applicability

In the power industry, the applicability of check valves is very strong. Whether it is high temperature, low temperature, corrosive liquids, or fluids under special conditions such as ultrasound and ultra-low temperature, check valves are capable of handling them.

3. Good sealing performance

Compared to other valves, check valves have better sealing performance. Generally, check valves use springs and other components to ensure that the valve disc can tightly fit the valve seat, thereby achieving the purpose of sealing. In pipelines, whether under low pressure, high pressure, high temperature or low temperature conditions, check valves can ensure good sealing.

4. Low flow resistance

Generally speaking, the flow resistance of check valves is relatively small. Its Drag coefficient is generally about 0.3, which means that the fluid in the pipeline is easier to pass. Therefore, the use of check valves can also reduce the resistance of the pipeline system, thereby reducing the operating cost of the pipeline.

5. Widely used

Check valves are widely used in the power industry. Generally speaking, check valves are suitable for various places such as power plants, air conditioning systems, engineering systems, and gas systems. In addition, check valves are often used in other industries such as urban water supply and drainage systems, chemical systems, and petrochemical systems, and their application fields are very extensive.

The above are several characteristics of commonly used check valves in the power industry. When using check valves, it is necessary to pay attention to the installation position and direction of the valve, and also ensure the cleaning and maintenance of the valve, so as to ensure that the check valve can smoothly control the valve and operate the system.
