Description

Technical Field

[0001] This utility model relates to the field of hydraulic testing technology, and more specifically, to a converter device for hydraulic testing. Background Technology

[0002] A directional valve utilizes the change in the relative position between the valve core and the valve body to connect and disconnect certain oil circuits within the valve, thereby meeting the requirements of various directional functions in a hydraulic system. For example, a hydraulic testing converter assembly (application number CN201420255593.1) is described. This utility model relates to a hydraulic testing converter assembly, characterized by: a base plate disposed on the mounting surface of a test bench and a transition plate disposed on the mounting surface of the directional valve. The base plate has a first set of channels corresponding to the oil port groups on the test bench, and the transition plate has a second set of channels corresponding to the oil port groups on the directional valve. The base plate and the transition plate are detachable and can be connected. When the base plate and the transition plate are connected, the first and second sets of channels are interconnected, thereby enabling the connection between the directional valve and the test bench. This converter assembly structure overcomes the limitation of traditional test bench mounting surfaces that can only accommodate a single type of directional valve, thus improving the applicability of the test bench.

[0003] However, in the specific implementation of the above-mentioned technical solutions, the connection port of the test equipment and the connection port of the hydraulic pump to be tested may not be able to connect perfectly. The existing connection conditions will produce some angles that affect the smoothness of hydraulic pumping. Utility Model Content
