Problems solved by technology

[0002] The traditional impeller-type gas flow metering device drives the rotation of the impeller through the flow of gas. The gas flow is linearly related to the speed of the impeller. The larger the flow rate, the faster the speed of the impeller. The rotation of the impeller is accumulated by driving the mechanical counting device. The flow rate of gas, the traditional impeller flow metering device has a simple structure, but there are some defects: First, at low flow rate, due to the low flow rate of gas, the impeller cannot rotate, so it cannot accurately measure small flow rate

Abstract

The invention relates to an impeller type gas flow metering device which comprises a main shell provided with an impeller mechanism, an upper air chamber, a lower air chamber, an air inlet channel, a valve mechanism, an air outlet channel and a detection mechanism. The valve mechanism comprises a valve seat and a valve rotatably arranged on the valve seat, the valve is positioned between the air inlet channel and the upper air chamber and provided with an adjusting component for adjusting opening of the valve according to flow, and the air inlet channel is provided with a filtering mechanism for filtering external gas. By the scheme, the impeller type gas flow metering device is used for intelligently adjusting the size of the valve and capable of purifying gas flow.

Description

technical field [0001] The invention relates to a flow metering device, in particular to an impeller type gas flow metering device. Background technique [0002] The traditional impeller-type gas flow metering device drives the rotation of the impeller through the flow of gas. The gas flow is linearly related to the speed of the impeller. The larger the flow rate, the faster the speed of the impeller. The rotation of the impeller is accumulated by driving the mechanical counting device. For the flow of gas, the traditional impeller flow metering device has a simple structure, but there are some defects: First, the impeller cannot rotate due to the low flow rate of the gas at low flow rate, so it cannot accurately measure small flow rates. The second is that the speed of the impeller is too fast under the large flow rate, and the parts such as the impeller bearing are easy to wear, resulting in a short service life of the flow metering device. The ratio to the minimum flow r...
