An electrically-controlled inching valve comprises a valve body. A moving spool is mounted in the valve body. An electrohydraulic proportional overflow valve mount and an end cover plate are mounted at two ends of the valve body respectively. A pressure spring abutted to one end of the moving spool is mounted in the end cover plate. An electrohydraulic proportional flow valve with a control coil is mounted on the electrohydraulic proportional overflow valve mount. The valve body is provided with an oil incoming passage, an oil outgoing passage and an oil return passage; the passages are communicated with corresponding circular grooves of the moving spool. The oil outgoing passage is communicated with an oil inlet of the electrohydraulic proportional flow valve and the end, at one end of the electrohydraulic proportional overflow valve mount, of the moving spool through damping small ducts in the valve body. The electrically-controlled inching valve has the advantages that the valve is simple in structure and convenient and reliable to use, sliding abrasion condition of a friction plate in a clutch can be controlled effectively, remote operation is achieved, wireless remote control under special conditions such as operation in unmanned submersibles is achieved, and operational response is fast, flexible and reliable.
Description
technical field [0001] The invention relates to an electro-hydraulic proportional control micro-valve, which is mainly used in ships and other transmission devices with wet hydraulic friction clutches, and can continuously change the control pressure of the clutch within a certain range, so that the clutch is in different positions. The sliding grinding state belongs to the technical field of pressure control valves. Background technique [0002] The existing micro-control valves used on ship transmissions are basically mechanical, which change the pressure through the rotation of the mechanical handle, and the ship driver manipulates the mechanical handle through a long massaging flexible shaft. Remote operation; wireless remote control under special working conditions cannot be realized, such as unmanned submersibles; the response is not fast enough. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art,...
