Digital valve test system

The present invention relates to a test system digital valves. Is solved using a digital oscilloscope is when the test valve duty cycle are time-consuming and low efficiency test, the test results of the test subject to interference and high cost problems, the present invention provides a digital valve test system, including tanks, pumps, oil feed channel, four subjects a digital valve piston cylinder and the oil return passage, the pump inlet connected to the tank, the oil outlet is connected with the intake passage, the intake passage has two branches, with the first, second connected digital valves test oil inlet, a first valve being a first digital sample cavity oil outlet port connected to the hydraulic cylinder, the second valve is a second digital sample cavity oil outlet port connected to the hydraulic cylinder, third and fourth digital valves were tested oil outlet are connected to one end of the oil return passage, and the other end of the oil return passage connected to the tank. Digital valve test system using the present invention, it is possible to accurately predict the actual digital valve duty cycle, to provide protection for the practical application of digital valves.
