An anti-leakage natural gas shut-off device and its use method

Abstract

The invention discloses an anti-leakage natural gas shut-off device and its use method, and relates to a natural gas shut-off device, which specifically includes a transport vehicle, a vehicle board and a natural gas storage tank. During the natural gas leakage process, when the natural gas leaks, it is discharged from the gas outlet pipe. The gas sensor recognizes that there is a natural gas leak, and the motor is first turned on by the controller. After a period of time, the meshing effect of the gear and the rack rod, and the sealing is good, and the safety is increased; the outlet pipe is blocked by the way of sealing oil flow, when In the event of leakage, the sealing oil can be added automatically, thereby prolonging the sealing time, reducing the excessive addition of sealing oil, and reducing the waste of resources; the vibration-absorbing bracket can buffer the shaking of the natural gas storage tank during transportation, and improve the stability of the natural gas storage tank during transportation. Increased natural gas storage tank stability reduces the likelihood of valve misalignment, thereby preventing the increased likelihood of leaks.

Description

technical field [0001] The invention relates to a natural gas closing device, in particular to an anti-leakage natural gas closing device and a method for using the same. 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 volcanic gas, coalbed 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 hydrocarbons and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, 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 through the natural gas storage tank installed on the tr...

AI Technical Summary

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
