Abstract

The invention relates to an adjustable throttling device which comprises an outer sleeve, a plurality of first inner core columns, a second inner core column, a third inner core column, a limiting clamping ring, a limiting rib and a limiting clamping ring. The first inner core columns, the second inner core columns and the third inner core columns are sequentially and fixedly connected in the axial direction through positioning bosses and positioning grooves and then are axially positioned through the outer sleeve, the limiting ribs on the outer sleeve and the limiting clamping ring. The outer diameter of the second inner core column is smaller than that of the first inner core column, the third inner core column comprises an open cylinder part and a hollow cylinder part, and the outer diameter of the hollow cylinder part is larger than that of the open cylinder part. When the pressure reduction requirement is changed, redesign is not needed, the number of the first inner core columns, the diameter of the outer cylinder of the second inner core column and the number and hole diameter of the throttling holes in the third inner core column are determined and selected only through simple calculation, and the purpose that one set of device is reused is achieved.

Description

technical field [0001] The invention relates to a throttling device, in particular to a device that does not need to be redesigned when the demand for pressure reduction changes, but only needs to be calculated simply to determine the number of the first inner core column, and to determine the diameter and diameter of the second inner core column and the outer cylinder. The number and diameter of the throttling holes on the third inner core column are adjustable throttling devices for the purpose of reusing a set of devices. Background technique [0002] At present, the traditional throttling orifice flowmeter is used for specific working conditions. When the working conditions change, the follow-up device needs to be redesigned, and it is prone to step pressure drop and cavitation. When measuring high-temperature and high-pressure fluids, The structure of the throttling orifice flowmeter is easy to deform, and it is prone to structural changes caused by cavitation, which ma...
