Description

TECHNICAL FIELD

[0001] The application relates to the technical field of intake valve detection, in particular to an engine intake valve pressure detection auxiliary device. BACKGROUND

[0002] The engine intake valve is a core component for controlling air to enter a combustion chamber, and the performance of the engine intake valve directly affects engine power output, fuel efficiency and emission levels. The pressure detection of the engine intake valve is for detecting a valve core, and the detection mode is to place the valve core into a placing groove of a detection device, then press the upper end of a core rod by means of an electric push rod, so that the core rod moves downward and opens a channel, then injects oil inward, the oil flows through the inside of the valve core from bottom to top, and the flow pressure is monitored by a flow monitor after the oil comes out of the valve core to see whether the flow pressure reaches a preset value, and when the preset value is reached, the force required to press the core rod is confirmed. However, before and after the pressure detection step, sealing detection and flushing steps need to be performed respectively, so a single set of intake valves needs to be placed into three sets of devices in sequence for operation. Since the intake valve core is small in size and the size of the placing groove is consistent with the outer diameter of the intake valve core, manual taking and placing operation is inconvenient, and the operation of frequently replacing the intake valve core for detection is labor-wasting.
