Gas storage device

Abstract

The invention discloses a gas storage device which belongs to the field of petroleum chemical equipment. The gas storage device comprises a gas storage body and a gas storage unit positioned on the gas storage body, wherein the gas storage unit comprises a gas storage cavity positioned inside the gas storage body, a gravity slide block which is dynamically positioned inside the gas storage cavityin a sealing mode and can move up and down along the gas storage cavity, an electrifying coil which surrounds outside the gas storage cavity, a magnetic induction block which is coaxially positioned inside the gravity slide block, a gas inlet valve and a gas outlet valve, which communicate with the bottom of the gas storage cavity separately, wherein the gas inlet valve communicates with a gas supply pipeline, and the gas outlet valve communicates with a gas consumption pipeline. Through the gravity slide block, gas storage amount of the gas storage cavity which is inflated with gas every timecan be the same, so that the quantitative output purpose is achieved, and quantitative output still can be achieved even gas pressure is unstable. The electrifying coil is mutually matched with the magnetic induction block, so that gas pressure in the gas storage cavity can be regulated in real time, and therefore, a gas pressure regulating process is more convenient and reliable.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to a gas storage device. Background technique [0002] As a common gaseous fuel, natural gas is widely used in daily life, among which, natural gas usually needs to be used quantitatively, and, in certain cases, in order to obtain different combustion efficiencies, natural gas needs to be used after pressurization, so, how to Quantitative and reasonable pressurization of natural gas is of great significance for its normal use. [0003] At present, the amount of natural gas used is mostly determined by controlling the internal pressure and diameter of the natural gas pipeline and the circulation time of natural gas in the natural gas pipeline, so as to achieve the purpose of quantifying it. Moreover, natural gas pipeline pressurization equipment is often used to pressurize natural gas to a specific value. [0004] However, in the process of natural gas transportation, if ther...

Problems solved by technology

[0004] However, in the process of natural gas transportation, if the air pressure changes unstable, it will not only affect the above-mentioned judgment on the amount of natural gas used, making it impossible to quantify, but also not conducive to the combustion of natural gas

Moreover, in the process of pressurizing natural gas, it can only be pressurized to a specific value, which cannot cope with various emergency situations that require natural gas of different pressures
