Restriction Orifice Plate

Application scope

The orifice plate is an element installed in the pipeline to restrict the flow of the fluid or reduce the pressure of the fluid. It has the characteristics of simple structure, convenient installation, stability and reliability, and relatively low price. Therefore, it has been obtained in the fields of petroleum, chemical industry, electric power, etc. Widely used. The orifice plate is mainly used in the following occasions:

Where the process materials need to be depressurized and the accuracy requirements are not high.

When a large pressure drop is required upstream and downstream of the valve in the pipeline, in order to reduce the erosion of the valve by the fluid, when the gas flow through the orifice throttling does not produce a gas phase, an orifice plate can be connected upstream of the valve.

The place where the fluid needs small flow and continuous circulation, such as the flushing pipeline of the pump, the bypass pipeline of the hot standby pump (low flow protection pipeline), the analysis sampling tube and other places.

Places where pressure reduction is required to reduce noise or wear, such as gas or steam venting systems.
 

Work Principle

In the pipeline, install a restrictive orifice plate, when the fluid passes, because the flow area of the restrictor orifice plate is smaller than the cross section of the pipe,Formation of choke effect. As a result, the pressure decreases and the flow rate becomes smaller.
