Abstract

The invention relates to a three-rotor flowmeter made of a composite material. The three-rotor flowmeter comprises an outer shell, wherein the outer shell is provided with an inlet tube and an outlettube, one side, far from the outer shell, of the inlet tube is connected with a buffer tube through a flange, the inner side wall of the buffer tube is connected with multiple fixed plates, one end, far from the buffer tube, of each fixed plate is connected with a semicircular plate integrally, each semicircular plate is internally provided with a bidirectional motor, an output shaft of each bidirectional motor penetrates the semicircular plate and is connected with a rotating plate, the inner side wall of the buffer tube is provided with multiple first grooves, the bottom of the first grooveis provided with a first mini air cylinder, the first mini air cylinder is connected with a raise block that is in the first groove and fits with the opening area of the first groove, and the openingof the first groove is provided with a rubber ring. The three-rotor flowmeter has advantages of stable rotation, low noise, long service life, scouring resistance, and high flow metering.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a three-rotor flowmeter using composite materials. Background technique [0002] Positive displacement flowmeters are used for continuous or discontinuous measurement of liquid flow through pipes. The flowmeter mainly includes a housing, a metering chamber assembly, a precision adjuster, a counter, etc. When the liquid to be measured flows through the metering chamber, a pressure difference is formed at the inlet and outlet of the flowmeter, which drives the large rotor and small rotor to rotate, and at the same time transmits it to the counter through the gear transmission system to directly indicate the liquid weight of the flowmeter. [0003] Both the large rotor and the small rotor in the current three-rotor flowmeter are made of metal materials. During the rotation process, the large rotor and the small rotor present the disadvantages of instability, high noise and short...
