Valve and velocity sensor are connect with the controller respectively.
As a further improvement of the present invention, it is additionally provided with indicator light and contact, the contact is arranged in the low temperature
On quick action emergency valve, the indicator light includes red light and green light；The low temperature quick action emergency valve is closed with the contact pad simultaneously
The green light is connected, the low temperature quick action emergency valve unlatching separates with the contact and connects the red light.
As a further improvement of the present invention, the contact is arranged in the outlet chamber of the low temperature quick action emergency valve, institute
State the contact and the contact pad when low temperature quick action emergency valve is closed by being arranged on its valve rod.
As a further improvement of the present invention, when LNG tank vehicle travel speed is greater than 5km/h, the low temperature quick action emergency valve
It closes.
The beneficial effects of adopting the technical scheme are that
LNG tank vehicle emergency cut-off automatic control system of the present invention, three solenoid valves respectively with three on each pipeline
The connection of low temperature quick action emergency valve, when LNG tank vehicle travel speed is greater than 5km/h, solenoid valve control low temperature quick action emergency valve is closed,
Cutting LNG leaks path, while contact green light corresponding with contact pad lights, and sending standby signal shows that low temperature is promptly cut
Disconnected valve is turned off tank car and can drive safely.
Detailed description of the invention
