Problems solved by technology

[0003] The existing natural gas transportation is carried out by installing natural gas storage tanks on the transport vehicles. When driving on bumpy roads, the sloshing range of the natural gas storage tanks increases, resulting in changes in the valve position, which is easy to cause natural gas leakage. The existing closing device simply blocks the outlet pipe , relatively poor sealing, it is easy to cause natural gas leakage

Abstract

The invention discloses an anti-leakage natural gas closing device and a using method thereof, and relates to the natural gas closing device. The natural gas closing device specifically comprises a transport vehicle, a vehicle plate and a natural gas storage tank, in the natural gas leakage process, when natural gas leaks, the natural gas is discharged from a gas outlet pipe, a gas sensor recognizes natural gas leakage, a controller controls a motor to be started firstly, after the motor is started for a period of time, through the meshing effect of a gear and a rack rod, the sealing performance is good, and the safety is improved; the air outlet pipe is blocked in a sealing oil outflow mode, the sealing oil can be automatically added in the leakage process, the sealing time is prolonged,excessive adding of the sealing oil is reduced, and resource waste is reduced; and a damping support can buffer shaking generated during transportation of the natural gas storage tank, the stability of the natural gas storage tank in the transportation process is improved, the valve deviation possibility is reduced by increasing the stability of the natural gas storage tank, and leakage possibility is prevented from increasing.

Description

technical field [0001] The invention relates to a natural gas shut-off device, in particular to an anti-leakage natural gas shut-off device and a use method thereof. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcano gas, coal bed methane, and biologically generated gas, etc.). The definition of "natural gas" that people have used for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the formation. In petroleum geology, it usually refers to oil field gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases. [0003] The existing natural gas transportation is carried out by installing natural gas storage tanks on the transport vehic...
