Explosion-proof vehicle start-up and flame-out air circuit system and control method thereof

Abstract

An explosion-proof vehicle start-up and flame-out air circuit system comprises an air electromagnetic valve, an air motor, a flame-out air cylinder, an air manager, an air switch valve, an air control switch, an air button, an air main valve and an air control valve. A first pipeline, a second pipeline and a third pipeline are connected with an outlet of the air manager and are connected with an air inlet of the air switch valve, an air inlet of the air electromagnetic valve and an air inlet of the air main valve respectively, a fourth pipeline and a fifth pipeline are connected with an executing opening of the air switch valve and connected with an air inlet of the air control valve and an air inlet of the air control switch respectively, an executing opening of the air control valve is connected with the flame-out air cylinder, a sixth pipeline and a seventh pipeline are connected with an executing opening of the air electromagnetic valve and are connected with a control opening of the air control valve and an air inlet of the air button respectively, an executing opening of the air button is connected with a control opening of the air main valve through an eighth pipeline, and an executing opening of the air main valve is connected with the air motor through a ninth pipeline. Both a circuit of a vehicle and the air circuit system of the vehicle are simplified, and cost of the explosion-proof vehicle is reduced.

Description

technical field [0001] The invention relates to an explosion-proof vehicle start-up and flameout air circuit system and a control method thereof. Background technique [0002] Many explosion-proof vehicles in coal mines need to perform self-inspection when starting. Only when the surface temperature of the diesel engine, oil pressure, exhaust temperature, cooling water temperature, water level of the exhaust gas treatment tank and other parameters meet the requirements, the air motor starts to drive the diesel engine to work. Therefore, an air solenoid valve is needed in the starting system to control the starting system. In addition, the above-mentioned parameters need to be monitored throughout the working process of the explosion-proof vehicle. When these indicators are exceeded, another air solenoid valve is used to cut off the flame-out cylinder, and the diesel engine to turn off the fire. Since the explosion-proof vehicle needs to use an air solenoid valve for starti...

AI Technical Summary

Problems solved by technology

Because explosion-proof vehicles need to use an air solenoid valve for starting and an air solenoid valve for flameout, the circuit and air circuit system need to control the two valves separately, so the circuit and air circuit system are relatively complicated.
