Abstract

The invention provides a high-precision low-pressure gas generating device capable of measuring flow speed . The high-precision low-pressure gas generating device comprises a pressure supply component, a gas supply component and a connecting component connected between the pressure supply component and the gas supply component. Stable low-pressure gas is provided through position potential energy difference delta H of pressurizing liquid, pressure precision of the gas is high and can reach 0.1KPa, pressure stability of the provided gas is high, and gas pressure does not float; the flow speed of the gas can be measured, and measuring accuracy is high and is 1ml / s; the provided gas is not limited to be air and can be any gas; especially for flammable and explosive gas like methane, gas supply quantity is limited, so that safety is improved. The high-precision low-pressure gas generating device is simple in structure and low in cost. The invention further provides a using method of the device.

Description

technical field [0001] The invention relates to a high-precision low-pressure gas generating device capable of measuring flow velocity and a using method thereof. Background technique [0002] Stable low-pressure gas (range: 0 to 100 kPa) plays an extremely important role in the fields of medical machinery, chemical industry, biological environment, and material gas permeability measurement. In medicine, a stable low-pressure environment is conducive to providing fresh gases such as oxygen and anesthetic gas to patients, such as oxygen supply devices and anesthesia machines; in biology, organisms such as plants and bacteria must be cultivated in a low-pressure environment, such as plants The leaves are cultivated in high-concentration low-pressure carbon dioxide, etc.; in materials science, the measurement of the air permeability of nanomaterials or porous materials requires a stable low-pressure environment, such as the air permeability test of the air-tight layer of a land...
