a balance flow meter

Abstract

The invention discloses a novel balance flowmeter. The novel balance flowmeter comprises a pipe body, wherein the top of the pipe body is communicated with a first long pipe; a dust removal mechanismis arranged on the inner wall of a rubber ring; grooves are formed in the top and the bottom of the inner wall of a second flange; and rubber sleeves are fixedly connected to the inner walls of the grooves. According to the novel balance flowmeter, through the cooperation of a filter plate, a square plate and a transverse plate, the novel balance flowmeter can work in a place with a poor environment, air cleaning is not needed, dust is less, the relative temperature is low, natural ventilation is good, and the situation that the novel balance flowmeter works in a place close to the place emitting dust is avoided; through the cooperation of a pipe body groove, a heating wire and a water inlet valve, the internal temperature of the novel balance flowmeter can be adjusted, then the novel balance flowmeter can normally work at the temperature lower than 0 DEG C in winter and higher than 45 DEG C in summer, and the situation that the novel balance flowmeter works beyond the temperature range, and consequently the flow value calculated by the balance flowmeter in a pipeline is inaccurate is prevented.

Description

technical field [0001] The invention relates to the technical field of balance flow meters, in particular to a balance flow meter. Background technique [0002] The balanced flowmeter is a revolutionary differential pressure flowmeter, its working principle is the same as other differential pressure flowmeters, it is based on the principle of energy conversion in the sealed pipeline, in the case of ideal fluid, the flow in the pipeline and the differential Proportional to the square root of the pressure; the measured differential pressure value can be used to calculate the flow in the pipeline according to the Bernoulli equation. Although the existing balance flowmeter can realize the calculation of the flow in the pipeline, the balance flowmeter needs to work in clean air, less dust, relatively low temperature, good natural ventilation www.cechina.cn, and avoid working near places that emit dust. Unable to work in a place with a poor environment, and the requirements for t...
