Abstract

The invention relates to a volume-type gas flowmeter for measuring gas flows, in particular to a gas flowmeter with a suspended single rotor. The gas flowmeter comprises a hollow shell and a rotor arranged in the hollow shell, wherein the rotor comprises a horizontal round plate and a round ring fixed with the periphery of the horizontal round plate; one side of the round ring is provided with an opening which extends onto the horizontal round plate and forms a conical opening on the same; bearings are fixed on a ring body and on two sides of the opening of the round ring; stop plates are fixed between the hollow shell and an upper positioning cylinder and between the hollow shell and a lower positioning cylinder; and outer rings of the bearings on the ring body at the position of the opening are in contact with the stop plates. When the rotor moves, frictional resistance among the rotor and the stop plates is lowered, so that service life of the gas flowmeter is prolonged, and the precision of the gas flowmeter is increased.

Description

technical field [0001] The invention relates to a volumetric gas flowmeter for measuring gas flow, in particular to a suspended single-rotor gas flowmeter. Background technique [0002] At present, there is a rotary-floating single-rotor flowmeter. Although it has the advantages of simple structure, convenient maintenance, easy processing, and not easy to jam among positive displacement flowmeters, there is direct friction between the rotor opening and the positioning baffle. The surface is large, and the rotor is not positioned and fixed, resulting in the natural sinking of the rotor, which not only wears seriously, but also forms a certain resistance. Without liquid lubrication, it is impossible to measure the gas, which limits the scope of application. Contents of the invention [0003] In order to solve the problems of serious friction between the rotor opening and the positioning baffle plate of the rotating-floating single-rotor flowmeter and the problem that the rot...
