Abstract
The invention relates to the design of an auxiliary hydraulic combination valve which is an important component for an auxiliary hydraulic system of a helicopter. The design is characterized in that the auxiliary combination valve comprises a first one-way valve (1), a quick release self-closing valve (2), a pressure oil filter (3), a pressure annunciator (4), a safety valve (5), a second one-way valve (6), a third one-way valve component (7) and a third one-way valve (8). The auxiliary hydraulic combination valve has the functions of pressure transmission, overpressure protection, low pressure alarm, pressure indication, hydraulic oil liquid filter and oil blockage indication provision and is provided with a quick release connector for ground tests.
Description
Technical field:
The present invention relates to a kind of auxiliary hydraulic pressure combination valve design, is the important component part of helicopter auxiliary hydraulic system.
Background technology:
Helicopter auxiliary hydraulic system is used for carrying out rotor brake, wheel braking and the folding and unfolding of deck store door. Aloft for the emergency backup of left system, whenWhen left system decompression, it is left system voltage supply. Auxiliary hydraulic system also can be used for ground check and brake accumulator pressurising. Auxiliary hydraulic pressure combination valve is auxiliaryHelp part important in hydraulic system.
Summary of the invention:
The invention provides a kind of auxiliary hydraulic pressure combination valve, provide the energy for helicopter being carried out to rotor brake, wheel braking and deck store door receipts.
Product function block diagram as shown in Figure 1.
The technical scheme that the present invention takes is: this Assisted Combinatorial valve comprises the first check valve 1, quick-release Self-sealing valve 2, pressure oil filter 3, pressure signal device4, safety valve 5, the second check valve 6, the 3rd check valve assembly 7, the 3rd check valve 8 form. Wherein, the first check valve 1 one end and auxiliary electricalMoving pump connects, and first check valve 1 other end is filtered 3 one end with pressure oil and is connected, and quick-release Self-sealing valve 2 connects and the first check valve 1 and pressure oil filter 3Between, pressure oil is filtered 3 other ends Bonding pressure signalling means 4, safety valve 5 one end, the second check valve 6, check valve assembly 7 successively; Safety valve 5The other end is connected with the 3rd check valve 8.
Technique effect:
This auxiliary hydraulic pressure combination valve can be realized pressure transmission, overpressure protection, low pressure warning, pressure instruction, hydraulic oil liquid filtration, provide oil stifled instruction,And possess ground experiment use quick-release interface.
Brief description of the drawings:
Fig. 1 product function block diagram;
Fig. 2 product structure layout;
Wherein, 1 first check valve, 2 quick-release Self-sealing valves, 3 pressure oil filters, 4 pressure signal devices, 5 safety valves, 6 second check valves, 7 check valvesAssembly, 8 the 3rd check valves, 9 three-way connections, 10 housings, 11 adapter assemblies.
Detailed description of the invention:
Below in conjunction with Figure of description, the present invention is described in further detail.
The first check valve 1 is threaded connection and is arranged on housing 10 as shown in Figure 2, and quick-release Self-sealing valve 2 is by bolt, and pressure oil filter 3 is passed throughScrew is mounted on housing 10, and pressure signal device 4 is threaded connection and is arranged on housing 10, and safety valve 5 is threaded connection and is arranged onOn housing 10, the second check valve 6 and the 3rd check valve 8 are threaded connection and are arranged on housing 10, and check valve assembly 7 is threaded connection peaceBe contained on housing 10, three-way connection 9 is threaded connection and is arranged on housing 10.
In the time of auxiliary electrodynamic pump voltage supply, fluid enters voltage supply pipeline by the first check valve 1, after pressure oil filter 3, respectively by check valve 6,Check valve 8, then enters left hydraulic system by adapter assembly 11, enters brake system by three-way connection 9.
In the time of needs ground experiment and voltage supply, ground enters voltage supply pipeline for the fluid of force feed car by quick-release Self-sealing valve 2, after pressure oil filter 3,By check valve 6, check valve 8, then, by entering left hydraulic system by adapter assembly 11, enter brake system by three-way connection 9 respectively.
In the time being greater than 25.5MPa for pressure pressure, fluid, by safety valve 5, check valve assembly 7 releases, then flows back to hydraulic oil by fluid pressure lineCase.
