Eccentric reducers refer to a pipe connection device that connects two pipes and is often used in the design and construction of drainage systems. The main structure of this pipe connection device includes two pipes of different diameters and a branch pipe. Its design makes the central axes of the two pipes deviate from each other without intersecting.
Among stainless steel tube eccentric reducers, eccentric stainless steel reducers are mainly used as a connecting pipe fitting at the diameter change of the pipe. Eccentric stainless steel reducers are generally formed by shrinkage molding, and can also be pressed by shrinkage and expansion process. The stamping method can also be used for some special specifications of stainless steel reducers. Eccentric stainless steel reducers can not only produce stainless steel pipes of different diameters with steel pipes as raw materials, but also use steel plate forming method to press some special stainless steel pipes with different diameters. According to the inner surface size of the stainless steel reducer, the shape of the die is designed, and the steel plate is punched and stretched with the die.
The role and principle of stainless steel eccentric reducers:
1. Regulating flow and pressure
In the drainage system, the role of eccentric reducers is mainly to regulate flow and pressure by changing the diameter and connection method of the pipe. When the drainage volume is large, the drainage speed can be increased and the drainage time can be shortened by using a larger diameter pipe; conversely, when the drainage volume is small, the water flow speed can be reduced by using a smaller diameter pipe to avoid wasting water resources.
2. Reduce water flow noise
The pressure waves and water hammer generated by the interaction at the water pipe joints often cause violent vibrations and noise in the water flow. The eccentric reducer offsets the central axis of the two pipes to reduce the interaction of the water flow, thereby reducing the water flow noise and ensuring a quiet and comfortable living environment.
3. Discharge of sewage
Another very important function of the eccentric reducer is to discharge sewage into the treatment facilities or treatment equipment by connecting the distance between the drainage pipe and the main pipe. It can ensure the rapid and smooth discharge of sewage, prevent sewage backflow and blockage, and improve the treatment effect and utilization rate of sewage.
Application of stainless steel eccentric reducers:
Eccentric reducers are widely used in the design and construction of pipelines in drainage systems. Specifically, it is mainly used in the following fields: internal drainage systems of buildings; urban drainage systems and sewage treatment equipment; means systems of factories and industrial sites; rural water conservancy projects and drainage facilities.
