Title:
AUTOMATIC PRESSURE STABILIZING DEVICE AND METHOD FOR BOTTLED PETROLEUM LIQUEFIED GAS
Document Type and Number:
WIPO Patent Application WO/2022/151569
Kind Code:
A1
Abstract:
The present invention relates to an automatic pressure stabilizing device and method for bottled petroleum liquefied gas. The device comprises: a first component (3) disposed in a pressure reducing valve (2) of a gas cylinder (1) to sense airflow information in the cylinder and convert the airflow information into electrical information for output; a second component (4) that is located at the lower end of the gas cylinder (1) to measure the temperature of the bottle body and is connected to the first component (3) to receive the electrical information; and a third component (5) disposed at the bottom of the gas cylinder (1) to heat the bottle body, wherein the second component (4) is also connected to the third component (5) and controls, according to the measured temperature information of the bottle body and the received electrical information, the third component (5) to perform or not perform heating to maintain stable air pressure in the bottle. The device and the corresponding method enable the gas cylinder to always be in the best gasification state and pressure stabilized state, thereby improving combustion efficiency and achieving automatic heating.
