Example Embodiment

[0022] Example 1

[0023] Hydraulic reversing valve oil port test control device, including oil tank 1, filter temperature control device 2, control oil pump motor group 3, main oil pump motor group 4, oil inlet and return control valve group 5, oil port test process control bridge circuit 6, change To valve 7. The pump station consists of an oil tank, a filter temperature control device, a main oil pump motor unit and a control oil pump motor unit. The function of the oil pump motor unit is to provide a certain pressure and flow of pressure oil to the test system. The filtration temperature control system consists of an oil pump motor unit, two-stage filter, plate radiator and control valve to meet the oil cleanliness and test temperature control requirements of the test bench.

[0024] The hydraulic test control system is equipped with pressure gauges, pressure gauge switches, primary measurement instruments, manipulation force sensors, test pieces connecting oil ports and test ...

Abstract

The invention relates to a device for controlling the test of the oil port of a hydraulic reversing valve, and belongs to the valve testing technology field. The device comprises controlling valves and an oil duct, wherein the oil duct is connected with the controlling valves; the oil duct is connected with an oil tank and a pressure oil source. The device is characterized in that the oil port of the test reversing valve is respectively connected with the controlling valves; the controlling valves are connected into a controlling bridge circuit in parallel through the oil duct; the controlling bridge circuit is composed of the controlling valves and an overflow valve; after being connected in series, the controlling valves are connected in parallel; the overflow valve is connectedly installed among the controlling valves connected in series after being connected in parallel; the controlling bridge circuit is provided with an externally connected controlling valve; the externally connected controlling valve is connected with the oil supply oil duct of the pressure oil source; a controller is connected with the controlling valves and the overflow valve in the controlling device. By using the controlling device, the test process is simplified, the test efficiency is enhanced, the labor intensity is reduced, and the automation of the test process is realized.

Description

technical field [0001] The invention belongs to the technical field of valve testing, in particular to a hydraulic reversing valve oil port test control device. Background technique [0002] At present, the well-known technology JB / T8729.2 "Test method for hydraulic multi-way directional valve", according to the test items (such as Table 1), when the hydraulic multi-way directional valve is tested, sometimes the A and B oil ports are connected to oil, and sometimes it is necessary to The reversing valve A and B oil ports are blocked, and sometimes it is necessary to load the reversing valve A and B oil ports. This will result in frequent connection and disconnection of the test connection pipeline during the test, making the test process complicated and cumbersome, the test efficiency low, and increasing the labor intensity of the test personnel. [0003] Table 1 [0004] Contents of the invention [0005] In order to solve the technical problems existing in the known...
