DDTOP LGXL Restriction Orifice Plate

LGXL restriction orifice plate has the advantages of simple structure, easy processing, low manufacturing cost and convenient installation. Under the premise requirements of the process, the use of the orifice plate instead of the regulating valve to limit the flow rate or reduce the pressure will greatly reduce the cost of operation and maintenance. Therefore, it is widely used in process devices and plays an important role in the safe operation of device.

Description of DDTOP LGXL

LGXL restriction orifice plate is suitable for occasions such as automatic control and piping in engineering design. The following are several commonly used occasions:

  1. Where the fluid is required to pass continuously at a small flow rate, such as the analysis sampling pipeline, the flushing pipeline of the pump, the bypass pipeline of the hot standby pump, etc., LGXL restriction orifice plate can be installed to achieve.
  2. Where fluid pressure reduction is required, such as: installing a restriction orifice behind the control valve to reduce the pressure drop on the valve, reduce valve noise, reduce the wear of the valve seat and valve core, and avoid liquid flash behind the valve evaporation and cavitation phenomena extend the service life of the control valve; when the fluid needs to be depressurized, and where the accuracy of the depressurization is not high, the LGXL restriction orifice plate can be used to depressurize.
  3. Where fluid pressure reduction and flow restriction are required, such as: LGXL restriction orifice plate is installed on the bypass of the control valve to prevent the pressure relief from being too fast or the risk of liquid evacuation when the bypass is operated, and the piping is vented when the system produces a lot of noise due to large pressure drop, LGXL restriction orifice plate can be used to reduce the noise and improve the production environment.

Features

1.It has advantages of simple structure, easy processing, easy installation and stable performance.

2.Use restriction orifice plate instead of regulating valves to limit flow or reduce pressure, operating and maintenance cost can be greatly reduced.

3.Restriction orifice plate is divided into single hole plate and porous plate according to the number of holes in the orifice plate, and can be also divided into single stage and multi stage according to the number of orifice plates.

Applications

1.It is applied to the occasion where process materials needs to depressurize.

2.Large pressure drop is required in the upper and lower reaches of the valve in the pipeline, in order to reduce the erosion of the valve by fluid, when the flow through the orifice plate does not produce gas phase, the valve upstream series orifice plate can be used.

3.It is applied to the site where the fluid needs small flow and continuous flow, such as the flushing pipe of the pump, the bypass pipe of the hot standby pump (low flow protection pipe), the analytical sampling pipe and so on.

4.It is applied to the places where depressurization is required to reduce noise or wear, such as emptying systems.
