Title:
METERING DEVICE AND METHOD FOR MEASURING FLOW OF CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2018/137321
Kind Code:
A1
Abstract:
The present invention relates to the technical field of preparation of a polyurethane foam material. Provided are a metering device (12) and method for measuring a flow amount of carbon dioxide. The metering device (12) has a simple structure and a small size, and can precisely control an amount of conveyed liquid carbon dioxide. Moreover, one end of a metering pump (25) is connected to a sliding block (28). The sliding block (28) is movable on a horizontal bar (24), such that a vertical travel distance of a piston (33) can be changed, thereby changing a flow amount of carbon dioxide. Furthermore, a water channel (61) is arranged in a cylindrical body (31) of the metering pump (25), such that a refrigerant medium can be introduced to the water channel (61), thereby enabling carbon dioxide to maintain a constant temperature.
