Plural emergency system oil return quick release coupling in parallel on described emergency system oil return branch road.
Always the entering of described valve block, oil circuit according to the demand of pilot system arrange into, return the quantity of branch road.
Advantage of the present invention and effect are: the present invention adopts single channel to turn two-way hydraulic regulation module converts structure, achieve the oil sources that single cover hydraulic oil source is converted to two-way adjustable pressure, flow, there is following advantage with testing compared with to utilize on machine two to overlap fuel system that oil sources (normal oil sources and emergent oil sources) carries out testing in the past: 1 replaces space flight oil sources on two cover machines with a set of civilian ground oil sources, greatly reduces experimentation cost; 2 reduce design and installation difficulty: the rotating speed of ground oil sources easily designs use at rated speed range content, and on machine, oil sources rotating speed is ultrahigh rotating speed, drag add design difficulty with ground installation, and are not easy to safeguard; 3 reduce maintenance difficulties: ground oil sources is once go wrong, and maintenance will far less than oil sources on machine with the cycle more renewing part, and its cost is also far smaller than oil sources on machine.In addition, branch road has been selected to the throttle grverning valve integrating pressure-reducing function and throttle grverning function, its level of integration and maintainability, compared with realizing this function with a reduction valve with throttle grverning valve respectively, have greatly improved.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
Adopt the design of hydraulic regulation module, single cover hydraulic oil source is converted to the oil sources of two-way adjustable pressure, flow, to meet the job requirement of undercarriage.Have two fuel feeding branch roads in this example, wherein the charge oil pressure of normal fuel injection branch road and flow are without Secondary Control, directly consistent with the parameter of total oil supply system; And the pressure flow in emergent fuel feeding branch road has carried out the adjustment of pressure and flow by throttle grverning valve (the throttle grverning valve selected is integrated with reduction valve and throttle grverning two kinds of functions), its pressure versus flow is all not identical with the pressure versus flow of total oil supply system.This structure is applicable to the working environment that in this landing-gear system, two-way branch road fuel feeding can not work simultaneously.In case there is a need, plural pressure and Flow-rate adjustment branch road can be set.
(1) hydraulic regulation module installation, annexation
Use this hydraulic module, same oil sources can be realized under oil condition, be respectively the pressure versus flow that two branch roads provide different.
As shown in the figure, this hydraulic regulation module is made up of hydraulic power oil return quick release coupling 1, hydraulic power fuel feeding quick release coupling 2, emergency system fuel feeding quick release coupling 5, normal system fuel feeding quick release coupling 6, emergency system oil return quick release coupling 7, normal system oil return quick release coupling 8, valve block 3, high-pressure ball valve 4, multichannel table switch 9, series flow control valve 10 and pressure gauge 11.
First by the pressure of oil sources, Flow-rate adjustment to the maximum value just over undercarriage normal fluid pressure system demand pressure, flow.Then, hydraulic power oil return quick release coupling 1, hydraulic power fuel feeding quick release coupling 2 are connected with the oil return of oil sources and fuel feeding respectively, normal system fuel feeding quick release coupling 6 is connected with flow transducer entrance, normal system oil return quick release coupling 8 is connected with flow sensor outlet, emergency system fuel feeding quick release coupling 5 is connected with second flow transducer entrance, and emergency system oil return quick release coupling 7 is connected with second flow sensor outlet.Again multichannel table switch 9 is adjusted to normal system pressure display position, open high-pressure ball valve 4, start oil sources, coordinate adjustment oil sources throttle valve and hydraulic regulation module series flow control valve 10, make flow that is normal and emergency system reach the maximum value of undercarriage hydraulic system requirement.Regulate high-pressure ball valve 4 gradually, the maximum value making pressure that is normal and emergency system reach undercarriage hydraulic system to require, regulates series flow control valve 10, make normally and the flow of emergency system in the scope that undercarriage hydraulic system requires.Finally, normal system fuel feeding quick release coupling 6, normal system oil return quick release coupling 8 are connected T1 with undercarriage normal fluid pressure system fuel feeding P1 and oil return respectively, emergency system fuel feeding quick release coupling 5, emergency system oil return quick release coupling 7 are connected with undercarriage emergency hydraulic system fuel feeding P2 and oil return T2 respectively, open high-pressure ball valve 4, complete hydraulic regulation module and install.
(2) hydraulic regulation module effect
Carry out the corresponding relation test of hydraulic system pressure and flow with pressure gauge, flow transducer and traffic figure integrating instrument, by oil sources Character Comparison on ground hydraulic system performance and machine, it the results are shown in Table 1.
