Embodiment Construction

[0015] The structure diagram of the transfer liquid shunt is as follows: figure 2 Each annulus consists of fittings and conduits secured to end caps as shown. The folding ring is composed of eight joints and eight guide tubes, two of which are located inside the end cover and the remaining six joints are located outside the end cover, and the six joints located outside the end cover are right-angle joints respectively connected to the six paddle folding devices. Folded pipeline, the two internal joints are straight-through joints respectively connected to the folded pressure supply pipeline and the pressure accumulator, such as image 3 shown. The damper ring is composed of seven joints and five conduits, two of which are integrated on the shuttle valve, and six joints are respectively connected to the damper of the six blades, such as Figure 4 shown. The expansion loop is composed of seven joints and five conduits, one of which is integrated with the shuttle valve (such ...

Abstract

The invention is applied in the hydraulic folding system of the helicopter, and is an important part of the hydraulic folding system. A flow divider for transferring liquid, characterized in that the flow divider consists of three loops: a folding loop (1), an unfolding loop (2), a damper loop (3) and a reciprocating valve (4) composition. The invention integrates three loop pipes and a reciprocating valve, which can simplify the pipes of the hydraulic folding system. At the same time, the reciprocating valve can automatically select the pressure channel to supply pressure to the damper according to the pressure, so that the channel that needs to use the control signal can be omitted. Shut-off valve or reversing valve.

Description

Technical field: [0001] The invention is applied in the hydraulic folding system of the helicopter, and is an important part of the hydraulic folding system. Background technique: [0002] Among the domestic helicopters, the hydraulic folding system is a relatively new topic. Its difficulty lies in that the pipeline of the hydraulic folding system is relatively complicated and there are many components. Invention content: [0003] A flow divider used for transferring liquid can realize the folding and unfolding of the main rotor of the helicopter rotor in the hydraulic folding system of the helicopter. [0004] Such as figure 1 As shown, a flow divider for transferring liquid is composed of three loops: a folding loop 1 , an unfolding loop 2 , a damper loop 3 , and a reciprocating valve 4 . Folding ring 1, damper ring 3, and unfolding ring 2 are arranged in overlapping order from top to bottom, and fixedly connected; [0005] The joints on the outside of the folding rin...
