Abstract
This invention relates to one three-gear gas and double rotor flow meter for natural gas and coal gas, which comprises the structure as: meter chamber is connected to transfer magnetic steel, sensor, electrical meter, wherein, meter chamber has rotors; the rotor is for three gear spiral rotor in arc swing shape; the gear is composed of four section curves from tip to long swing line, short line and opening line and arc line; meter chamber connects double rotor through bearing and drive gear; the double rotor axis front end is connected to drive gear geared with two drive gears; one rotor back end is fixed on emission magnetic steel.
Description
Technical field
The invention belongs to the duplex rotor meter instrument that the measurements of gas flow such as a kind of rock gas, coal gas are used, particularly to the improvement of gas duplex rotor meter structure.
Background technology
Existing positive displacement gas meter is a waist wheel gas meter, and its rotor that adopts is a waist wheel shape, and this waist wheel rotor is a bidentate.Because bidentate waist wheel rotor formed curve when work is a cycloidal tooth profile, causing flowmeter is not continuous measurement when metering, has pulsation to produce, and measuring accuracy is inaccurate; And its serviceable life is limited.
Summary of the invention
The present invention is the shortcoming that overcomes above-mentioned waist wheel gas meter structure, and the gas duplex rotor meter that provides a kind of three tooth helical rotors to constitute makes it improve measuring accuracy and serviceable life.
A kind of 3-teeth double-rotor flowmeter, metering cavity 5 rear portions connect sender magnet steel 3, sensor 2, electronic counter 1, have rotor in the metering cavity 5, it is characterized in that rotor is three tooth helical rotors 4, and rotor is the Arc Cycloid type; Metering cavity 5 connects birotor by bearing 6, driven wheel 7, and rotor is fixedlyed connected with armature spindle; Birotor axle front end is fixedlyed connected with driven wheel 7 respectively, two driven wheel engagements; The fixedly connected sender magnet steel 3 in one rotor rear end.
Described three tooth helical rotors are the Arc Cycloid type, and profile of tooth is to be combined by four sections curves, connects to form from crown prolate cycloid successively, curtate cyclod, involute urve, circular arc line.
Principle of work of the present invention is that the gas duplex rotor meter promotes the rotor running by the inlet and outlet pressure difference, passes to sensor by the sender magnet steel, handles through smart electronics counting device to reach intelligent integrated flow and the instantaneous delivery of showing.
The present invention has overcome the shortcoming on above-mentioned existing flowmeter structure and the profile of tooth.3-teeth double-rotor flowmeter of the present invention adopts a pair of Arc Cycloid three tooth helical rotors, the advantage of its profile of tooth is, during a pair of gear teeth flank of tooth transmission is the engagement of a pair of convex-concave flank of tooth, induced normal curvature at conjugation contact point place is very little, on certain direction, can reach zero, improve the contact strength of the flank of tooth, be difficult for spot corrosion.Adopt this profile of tooth, make helical rotor in engaged transmission, possess good continuous potted line, running steadily can be widely used in the gas Trade Measures.This three tooth helical rotor engages and seals are good, running at the uniform velocity, steadily, pulse free, measuring accuracy height; The flank of tooth is friction not, the driven wheel that has, in engagement in rotation, make between rotor and the rotor do not rub, noise is little, increase serviceable life.

Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is Arc Cycloid three tooth helical rotor engaging structure synoptic diagram.
1 electronic counter, 2 sensors, 3 magnet steel, 4 helical rotors, 5 metering cavitys, 6 bearings, 7 driven wheels.
Embodiment
The present invention is provided by following examples and accompanying drawing thereof.See accompanying drawing 1～2.
A kind of 3-teeth double-rotor flowmeter, metering cavity 5 rear portions connect sender magnet steel 3, sensor 2, electronic counter 1, has rotor in the metering cavity 5, it is characterized in that rotor is three tooth helical rotors 4, rotor is the Arc Cycloid type, profile of tooth is to be combined by four sections curves, connects to form from crown prolate cycloid successively, curtate cyclod, involute urve, circular arc line.Metering cavity 5 connects birotor by bearing 6, driven wheel 7, and rotor is fixedlyed connected with armature spindle; Birotor axle front end is fixedlyed connected with driven wheel 7 respectively, two driven wheel engagements; The fixedly connected sender magnet steel 3 in one rotor rear end.
