Abstract

The invention discloses an S-shaped rotor structure for a stainless steel roots flowmeter, which is characterized in that a swing plate is fixedly connected inside a metering chamber through the action of a roller, the lower surfaces of the two ends of the swing plate are fixedly connected with rotating shafts, one end of each rotating shaft is fixedly connected with two guide plates, the two rotating shafts and the flow guide plate are symmetrically arranged through the central axis of the swing plate, a plurality of rotors are arranged on one side of each rotating shaft, and the rotors are fixedly connected to one side of the metering chamber. The beneficial effects are that the gas is decelerated again through the plurality of rotors, the gas is discharged through the gas outlets in thegaps, and the rotor increases the gas passing speed due to the action of the rotating beads and the track when the gas passes through the gap, so that the result influencing the gas flow rate is minimized, and the inner wall of the protective shell is prevented from deforming, and therefore, the rotor is pushed to rotate to discharge gas downwards to finish metering.

Description

technical field

[0001] The invention relates to the technical field of S-shaped rotor structure, in particular to an S-shaped rotor structure used in a stainless steel waist wheel flowmeter. Background technique

[0002] As a volumetric measuring instrument, the gas waist wheel flowmeter has a history of more than 100 years. It is widely used for its high precision, wide range, small size, light weight, convenient installation and maintenance, reliable use and durable service life. It is used for flow measurement of natural gas, coal gas, inert gas, air and other gases. It is an ideal flow measurement device for domestic and foreign city gas, oil field chemical industry, scientific research and other departments. Gas waist wheel flowmeter is mainly composed of housing, conjugate rotor and counting device and other components. A pair of conjugate rotors installed in the metering chamber are under the action of the outlet pressure difference (P,, P.) of the circulating gas, a...
