Description

Novel wedge-shaped flowmeter

Technical Field

The invention relates to the technical field of flowmeters, in particular to a novel wedge-shaped flowmeter.

Background

The wedge-shaped flowmeter is a novel throttling differential pressure type flow measuring instrument, can perform high-precision flow measurement under the condition of fluid which can be used at high viscosity and low Reynolds number, and has incomparable advantages and irreplaceable effects on flow measurement occasions with low flow rate, small flow and large pipe diameter. The wedge-shaped flowmeter is mainly used for measuring the flow of media such as high-viscosity heavy oil, residual oil, diesel oil, engine oil and the like, industrial gas, coke oven gas, blast furnace gas, producer gas, urban gas, hydrogen, nitrogen, air, water vapor, sewage liquid and the like. The flowmeter has simple structure, no movable parts, less wear caused by fluid, stable and reliable working performance and long service life. The measuring element and the pressure taking device of the device have special structures, and no retention or blockage is formed when the fluid passes through, and the pressure loss is small, so that the ideal choice is to carry out high-precision flow measurement under the condition of low Reynolds number.

Through retrieval chinese patent application No. CN201820768725.9, a novel wedge flowmeter is disclosed, including the straight tube, the straight tube both ends are provided with the ring flange, the straight tube middle part is provided with the wedge groove, wedge groove cooperation joint has the wedge, be provided with the sealing washer that agrees with mutually in the wedge groove on the wedge, the wedge middle part is connected with the fixed plate, be provided with the mobile device who is used for driving the wedge removal on the fixed plate, mobile device includes the actuating lever, be provided with latch device between actuating lever and the fixed plate. The novel wedge-shaped flowmeter can conveniently disassemble the V-shaped block, is convenient to clean the V-shaped block, and prevents the surface of the V-shaped block from being corroded or adhered with impurities after long-time use to cause reduction of the measurement effect

However, although the V-shaped block can be detached for cleaning, the structure of the scheme is complex, which results in a complicated process when the V-shaped block is mounted and detached for cleaning, and further affects the working efficiency. To this end, we propose a new wedge-shaped flowmeter.
