Anti-collapse valve detection device

Abstract

The invention discloses an anti-collapse valve detection device. The middle of a base (1) is vertically fixed with an upright post (2), the upper end of the upright post (2) is hinged with the lower end of a rotating column (3), the top end of the rotating column (3) is fixed with a handle (4), the upper end of the rotating column (3) is provided with a positioning block (5); an angle scale (6) is arranged near the upright post (2), the arc top of the arc edge of the angle scale (6) faces to the upper surface of the base (1), the middle part of the upper end of the angle scale (6) is fixed onthe rotating column (3); the lower part of the upright post (2) is provided with a detection pin (7), and the point end of the detection pin (7) points at a semicircular through hole (6a) in the angle scale (6) and is close to the arc edge of the semicircular through hole (6a). The invention can accurately detect and test whether an anti-collapse valve accords with the requirements on the national III standard, and has the characteristics of simple structure, easy implementation, convenient operation, accuracy and reliability, and the like.

Description

technical field [0001] The invention relates to a testing device, in particular to a testing device for a motorcycle anti-roll valve. Background technique [0002] In order to prevent and control the pollution of motorcycle pollutants to the environment and improve the ambient air quality, the national phase III standards for two-wheeled and three-wheeled motorcycles have put forward new regulations on the emission of exhaust pollutants from two-wheeled or three-wheeled motorcycles. In this case, in order to meet the national Ⅲ standard, some manufacturers add a fuel evaporation system to the motorcycle to balance the pressure inside and outside the fuel tank, and absorb the oil vapor in the fuel tank into the carbon tank to prevent the oil vapor from entering the atmosphere. polluted environment. [0003] The anti-dump valve is a key component of the fuel evaporation system of the motorcycle. It is connected to the pipeline between the fuel tank and the canister. When the ...

AI Technical Summary

Problems solved by technology

At present, all motorcycle manufacturers have not tested the anti-roll valves when receiving the anti-roll valves delivered by the supporting manufacturers, which may easily lead to lax quality control of incoming factories, so that some unqualified products can be successfully installed on motorcycles , thereby affecting the performance of the fuel evaporation system, causing unnecessary troubles such as repairs and returns
