Background
Commercial vehicle chassis is equipped with a plurality of gas receiver usually for satisfy the gas demand of driving, parking braking, functions such as clutch, selection gearshift helping hand. The air source of the air storage cylinder is from compressed high-temperature air, and even if the treated air also contains water vapor in a certain proportion under normal conditions, the water vapor is condensed into water in the air storage cylinder and is deposited at the bottom of the air storage cylinder, and the water vapor can even freeze to block the water outlet when the air temperature is lower. Accumulated water in the air storage cylinder occupies the air storage space in an extruding manner, so that the air storage capacity is reduced, and a braking system and a power assisting system can be failed in serious cases. Therefore, accumulated water in the air storage cylinder needs to be drained in time, and particularly, when the water outlet is frozen, the ice needs to be melted by heating, so that the water outlet of the air storage cylinder is ensured to be smooth.
At present, most commercial automobile air cylinders are provided with mechanical drainage devices, and drivers manually drain water in a manner of pulling a drain valve by hands, such as Chinese utility model patent 'air cylinder manual drainage system' (application number: 201620200664.7, published date: 2016-08-17), Chinese utility model patent 'air cylinder drain valve' (application number: 201720060439.2, granted announcement date: 2017-10-27), Chinese utility model patent 'passenger car air cylinder drainage device' (application number: 201220382357.7, granted announcement date: 2013-01-16), and Chinese invention patent application 'air cylinder drain valve' (application number: 201711444989.5, published date: 2018-04-20). These techniques rely primarily on manual methods to achieve air reservoir drainage.

The technologies simply connect the water drain valve with an actuating mechanism (comprising an electromagnetic valve and a push rod) to realize automatic control, but do not consider the ice melting and water draining functions.
With the development of technology, a heating type drain valve is also coming up, such as an intelligent drain valve (application number: 201910530904.8, published: 2019-10-15) in the chinese patent application. The drain valve comprises a valve body, a valve cavity is further arranged in the valve body, a water level sensor is mounted in the valve cavity, the drain valve further comprises a controller, the controller is connected with the water level sensor, a valve core is mounted in the valve cavity, and the controller controls the valve core to move up and down and drain water. The temperature sensor detects the temperature in the valve cavity and forms a temperature signal to be sent to the controller, and the controller is connected with the heating sheet and controls the heating sheet to work. It is through automatic acquisition ambient temperature information, with external controller cooperation, realizes the self-heating to the drain valve, prevents that ponding from condensing into ice in the drain valve, and the drainage function is inefficacy.
However, since the heating type drain valve adopts the heating sheet heated in a dot shape to heat the drain valve, the heating efficiency is low, the heat transfer is slow, the heat generation is not uniform, the service life of the valve body is influenced, and the water is not prevented. Because the point-like heat source has low heating efficiency and slow heat transfer, the valve body cannot be quickly heated to more than 0 ℃ in extremely cold weather; the service life of the valve body is reduced due to the thermal stress existing at different parts of the valve body caused by uneven heating; the heating plate is not waterproof, and the heating power can be reduced or even short-circuited after being affected with damp.
