Intelligent ice melting and water draining module for air cylinder of commercial vehicle

Abstract

The invention discloses an intelligent ice-melting and water-draining module for an air cylinder of a commercial vehicle. The ice-melting and water-draining module is rapid and timely in ice-melting and water-draining The intelligent ice melting and water draining module comprises a valve body (2), an electromagnet assembly (1) and a controller assembly (3), a water cavity (25) communicating with a water draining pipe (24) is formed in the valve body (2), and the electromagnet assembly (1) controls connection and disconnection of the water draining pipe (24) and the water cavity (25); the intelligent ice melting and water draining module further comprises a thermal resistance type heating film assembly (8) which is tightly attached to the outer wall of the valve body (2) and electrically connected with the controller assembly (3), and the thermal resistance type heating film assembly (8) comprises a heating film (81), a heating film gasket (82), a fixing screw (83), gum (84) and a heating film pressing plate (85); and the heating film (81) is pasted on the outer wall of the valve body (2) through gum (84), and the heating film pressing plate (85) fixes the heating film (81) on the outer wall of the valve body (2) in an attached mode through the fixing screw (83) and the heating film gasket (82).

Description

technical field [0001] The invention belongs to the technical field of vehicle braking control components, in particular to an intelligent ice-melting and drainage module for an air storage tank of a commercial vehicle. Background technique [0002] The commercial vehicle chassis is usually equipped with multiple air storage tanks to meet the air demand for functions such as driving, parking brake, clutch, and gear selection mechanism. The air source of the air storage tank comes from compressed high-temperature air. Usually, even the treated air contains a certain proportion of water vapor. The water vapor condenses into water in the air storage tank and deposits at the bottom of the air storage tank. When it is low, it will even freeze and block the water outlet. The accumulated water in the air storage tank occupies the air storage space, which reduces the storage capacity. In severe cases, it will cause the braking system and power assist system to fail. Therefore, it ...

Problems solved by technology

[0006] However, since the above-mentioned heated drain valve uses point-shaped heating plates to heat the drain valve, the heating efficiency is low, the heat transfer is slow, and the heat generation is uneven, which has the disadvantages of affecting the life of the valve body and not being waterproof.

Due to the low heating efficiency and slow heat transfer of the point heat source, it is impossible to quickly heat the valve body above 0°C in extremely cold weather; the thermal stress in different parts of the valve body caused by uneven heating will reduce the life of the valve body; Waterproof, the heating power will drop or even short circuit after getting wet
