Valve terminal for trailer brake test system

Abstract

The invention discloses a valve terminal for a trailer brake test system. The valve terminal comprises a valve terminal body, the valve terminal body is provided with an air source quick connector which is connected with an external air source and a tank body connection quick connector, and the external air source enters from the air source quick connector and is connected into a tested air storage tank from the tank body connection quick connector. A connecting valve terminal comprises the valve terminal body, the air source quick connector which is connected with an external air source and the tank body connection quick connector are arranged on the valve terminal body, and the external air source enters from the air source quick connector and is connected into an air storage tank from the tank body connection quick connector. The valve terminal body is provided with a second air pipe quick connector allowing a vehicle to be connected, and compressed air in the air storage tank is connected to a vehicle from the second air pipe quick connector through the tank body connection quick connector. The valve terminal for the trailer brake test system disclosed in the invention has theadvantages of simple structure, easy design and assembly and convenient gas path adjustment and distribution operations, and the real-time performance, accuracy and reliability of data in a testing process can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of trailer brake safety testing, in particular to a valve island used in a trailer brake testing system. Background technique [0002] In the production of semi-trailers, the detection of the brake air circuit is a very important task, which is related to the safety performance of the trailer and cannot be neglected. So far, there is no standardized professional testing device for testing the braking response time of tractors and semi-trailers in my country. There are similar testing devices in foreign countries, but they are not only single in function, but also expensive and cost-effective. [0003] At present, the air circuit control on the professional testing device used for trailer braking response time abroad adopts the distributed air circuit control principle, and the air circuit adjustment and distribution are very complicated. At the same time, the overall structure is complex and the maintenance ...
