Abstract

A feeding pump device of volume tube continually metering type comprises: a volume tube (1) provided with metering volume section (11), a dragging mechanism (2), and an unilateral inlet valve (8) and an unilateral outlet valve (7). Said volume tube (1) particularly have two unilateral inlet valves (8) and two unilateral outlet valves (7) provided in two ends of inner wall thereof respectively. A piston (9) connected to the said dragging mechanism (2) is provided in said volume tube (1). The present invention provides a design scheme of feeding pump, of which metering mode is based on measuring displacement of the piston, and takes reciprocation times of the piston as computation base. The unit of metering is the product of minimal distinguish unit of grating ruler and cross section area of metering volume section of the volume tube, and the pump has both the function of the conventional volume tube device and medium metering type feeding pump and develops it.

Description

BACKGROUND OF THE INVENTION [0001] This invention is involved with a device of feeding pump device of metering type, especially involved with a device of metering type feeding pump that can be used to measure the definite-quantity output and the flow of the liquid media, to demarcate the container volume and to calibrate the measurement instruments and devices of the liquid medium flow. [0002] The volume tube device known has no option but to conduct the metrology for part of medium passing through the volume tube device, whereas cannot conduct the definite-quantity output and metrology for all medium passing through the volume tube device. A known feeding pump metrology device such as a volume tube flow meter disclosed in Chinese Patent 90200439.5 has no option but to conduct the definite-quantity output for the medium whose flow is relatively small, and the minimum measuring unit normally is a fixed volume, and the size of the minimum unit determines the measurement deviation; suc...
