Detailed description

Product introduction of orifice flowmeter

Orifice and orifice flowmeters are designed to match the characteristics of gas drainage pipelines in coal mines. Orifice flowmeters are designed to calculate the gas drainage capacity of coal mines. Its structure is simple, and it is extremely convenient to use and calculate. Orifice flowmeter is an economical device for measuring gas flow.

Application and working principle

Coal mine gas drainage flow is measured by radial pressure extraction method. Orifice flowmeter When the continuous flow of fluid passes through the throttling device in the pipeline, the flow rate will increase. There is a static pressure difference between the upstream and downstream sides of the orifice device, and there is a difference between the flow rate and the pressure difference. Constant relationship, so the flow rate of the fluid can be calculated by measuring the pressure difference.

Composition of product structure

Orifice flowmeters are mainly composed of: fluid inlet pipe, pressure taking nozzle, sealing ring, connecting bolts and nuts, flange, orifice plate, seal, fluid outlet pipe, etc. The orifice plate is a circular thin plate with circular openings and symmetrical with respect to the axis of the openings. The orifice plates with different inner diameters of pipes have similar geometric structures.
