Abstract

The invention relates to a performance detection tester of a CNG fuel system assembly pressure relief device for a vehicle. A gas inlet is connected with the inlet end of a valve block base through a hand-operated valve and a pressure regulating valve; the outlet end of the valve block base is divided into multiple branches, and each branch is connected with a PRD port in the side wall of a high-temperature test box sequentially through the hand-operated valve, a stop valve and a one-way valve; the gas inlet is connected with one end of the stop valve through the hand-operated valve, and the other end of the stop valve is connected with one end of the pressure regulating valve; one end of the pressure regulating valve is divided into two branches, one branch is connected with a PRD connection opening in a valve block in a low-temperature test box through the hand-operated valve, and the other branch is connected with a PRD connection opening in a valve block in the high-temperature test box through the hand-operated valve; the gas inlet is further connected with one end of the hand-operated valve through a pipeline, and the other end of the hand-operated valve is connected with a PRD port in a high-temperature furnace through the pressure regulating valve; the PRD port is further connected with one end of a thermal discharge pressure relief hand-operated valve. The performance detection tester can be used for testing PRD performance.

Description

technical field [0001] The invention relates to the technical field of vehicle gas cylinder detection, in particular to a performance testing machine for the pressure relief device of a CNG fuel system component used in a vehicle, and the test object is the pressure relief device in a CNG fuel system component PRD"). Background technique [0002] The CNG fuel system for vehicles is an additional device that uses compressed natural gas as the fuel raw material on the basis of the original single fuel supply system of the prototype vehicle. After the installation, the power performance of the vehicle is reduced by no more than 5%. The existing CNG fuel system for vehicles consists of three parts: gas storage and gas supply, decompression and control. The gas storage and supply part refers to the device for storing CNG, which is mainly composed of a fuel container, a high-pressure solenoid valve, a pressure gauge, a filling nozzle, and a high-pressure pipeline. The pressuriza...
