Product details


When the fluid flows in the pipeline, due to the local resistance of the orifice plate, the pressure of the fluid is reduced and the energy loss is caused. This phenomenon is called throttling in thermodynamics.






Characteristic:



▲Flow restriction orifice plate has simple structure, firm, stable and reliable performance, long service life and low price.



▲Executive standard:ASME ISO-5167.



▲It is widely applied, all single-phase flow can be measured, some miscible flow can also be applied.



▲The measurement fluid must be a phase-free flow, that is, no phase change occurs when the fluid flows through the throttle











Install Requirement :



1. The center of orifice plate, flange center, pipe center and gasket shall be concentric, and the degree of difference shall not exceed 0.002d/beta.



2. Fluid must be filled with pipes and throttling devices and continuously through the pipes.



3. The positive and negative pressure direction of the orifice plate, and the upstream and downstream pressure taking flange shall conform to the flow direction of the medium.







Prevent cavitation:



The pressure pvc at the cross section of the control flow is controlled to keep the pressure not lower than the saturated steam pressure pv of the liquid, which is a fundamental measure to prevent cavitation. For pipes with a larger pressure drop, it is possible to step down to ensure that the pressure is greater than the saturated vapor pressure of the liquid when the medium passes through each of the downflow sections.
