SIMULATION TEST APPARATUS FOR DETECTING NOZZLE

WIPO Patent Application WO/2019/222967

A1

A simulation test apparatus for detecting a nozzle, comprising: an air pressure regulation apparatus, a first valve (100), a second valve (200), a fuel storage apparatus (21), a third valve (300), a pump component (23), a test part (600), and a controller. The controller is separately connected to the first valve (100), the second valve (200), and the third valve (300); under the control of the controller, the simulation test apparatus forms a first circuit and a second circuit; the first circuit comprises the pump component (23), the third valve (300), the fuel storage apparatus (21), the second valve (200), and an outlet (15); the second circuit comprises the air pressure regulation apparatus, the first valve (100), the second valve (200), the fuel storage apparatus (21), the third valve (300), and the test part (600). The simulation test apparatus performs bidirectional cleaning by means of the two circuits, thereby improving the accuracy of a test result and prolonging the service life.
