Detailed description of the invention
The embodiment of the hoisting circuit integration module of ship crane hydraulic system of the present invention: as Figure 1-3, comprise the valve body integrated installing seat 1 for being serially connected between system two working connections 8, valve body integrated installing seat 1 is rectangular structure, two serial interfaces of valve body integrated installing seat 1 are arranged on its left and right side respectively, and two serial interfaces are connected to left fuel inlet fitting 2 and right fuel inlet fitting 6; The upper surface of valve body integrated installing seat 1 is installed with flush valve 3, the leading flank of valve body integrated installing seat 1 is installed with the flow regulating valve 4 and solenoid directional control valve 5 arranged successively left and right, flush valve 3, flow regulating valve 4 and solenoid directional control valve 5 all can adopt control cock structure of the prior art, wherein, flush valve 3 have two oil inlets, a return opening and two that be connected with two oil inlets respectively, for assembling the spool oil duct of spool, flow regulating valve 4 and solenoid directional control valve 5 all have an oil inlet and an oil outlet.In valve body integrated installing seat 1, have the first oil circuit 10 be connected between two serial interfaces, flow regulating valve 4 and solenoid directional control valve 5 are connected on the first oil circuit 10 successively; The second oil circuit 11 is connected between two oil inlets of flush valve 3 and two serial interfaces of valve body integrated installing seat, in addition, the trailing flank of valve body integrated installing seat 1 is provided with oil return interface, be connected with the 3rd oil duct between oil return interface and the return opening of flush valve, oil return interface is connected with back leakage connection 7.
As further optimization, described flush valve 3 adopts the board-like flush valve be fixed by screws on valve body integrated installing seat, described flow regulating valve 4 is fixedly be inserted into the cartridge throttle valve on valve body integrated installing seat, described solenoid directional control valve 5 is the plug-in solenoid directional control valve be fixedly inserted on valve body integrated installing seat, and this mounting means of three control cock is convenient to dismounting and maintenance.
During use, back leakage connection 7 is connected with oil sump tank, for two working connections 8 of hydraulic efficiency pressure system, operationally can there is relative change in oil pressure therebetween, as shown in Figure 3, when working connection normally works, namely the oil pressure of two working connections is equal for specific works principle, solenoid directional control valve 5 is energized and is disconnected by the first oil duct 10, passes through from the first oil duct 10 without hydraulic oil; When left side working connection be high pressure oil, right side working connection be low pressure oil time, the spool that the high pressure oil entered by left fuel inlet fitting 2 promotes flush valve 3 moves right, right fuel inlet fitting 6 is communicated with the back leakage connection 7 of flush valve 3 by the second oil duct of its correspondence, and low pressure side part high temperature oil gets back to fuel tank cooling; When right side working connection be high pressure oil, left side working connection be low pressure oil time, the high pressure oil entered by right fuel inlet fitting 6 promotes flush valve core and moves to the left, left fuel inlet fitting 2 is communicated with the back leakage connection 7 of flush valve 3 by the second oil duct corresponding with it, and low pressure side part high temperature oil gets back to fuel tank cooling; When working connection is emergency rating, first oil duct is opened by solenoid directional control valve 5 power-off, form a little loop, the hydraulic oil of two working connections circulates in this minor loop, flow regulating valve 4 passes through the hydraulic fluid flow rate of control first oil duct, the work speed of adjustment actuating mechanism, and the oil pressure of two working connections is equal simultaneously, the spool of flush valve 3 mediates state, and back leakage connection 7 and two working connections all disconnect.
