Eccentric reducer is also called the eccentric reducer, both ends of pipe diameter, used to connect different diameter tubes or variable diameter flange. Concentric reducer at both ends of the tube, circle, on the same axis diameter changes, in terms of axis of pipe position, the position of the pipe is changeless, commonly used in gas or liquid vertical pipe diameter changes. Eccentric reducer ends cut inside nozzle circumference, commonly used in horizontal liquid pipeline.
Eccentric reducer adopts reducing row of water heater technology, regardless of spring, summer, autumn and winter seasons change, even in cloudy weather, rain, snow, also because of its high efficiency and has the characteristics of a good hot bath temperature reached first. At the same time, the more significant effect of energy conservation and emissions reduction, by reducing close technical water heater thermal efficiency can reach 73%, power saving, coal saving, and reduce carbon emissions. Reducing pipe roundness should not be greater than 1% of the corresponding end diameter, and the allowable deviation of plus or minus 3 mm.
Eccentric reducer nozzle tangent point upward, known as the roof installation, commonly used in pump suction, exhaust, cutting down as bottom flat installation, generally used for valve installation, use the net. Concentric reducer is advantageous to the fluid flow, at the time of variable diameter less interference on the fluid flow pattern, therefore vertical flow of gas and liquid pipelines using concentric reducer. Eccentric reducer with a side is flat, favors the exhaust or drainage, convenient driving and maintenance, so the horizontal liquid pipeline with eccentric reducer in general.
