A kind of anti-load pressure regulator pre-charging mechanism with selection function

Abstract

The invention relates to an anti-load pressure regulator pre-pressurizing mechanism with a selecting function. The anti-load pressure regulator pre-pressurizing mechanism with the selecting function comprises a pre-pressurizing shell, a baffle, a pre-pressurizing spring and a valve. A longitudinal supporting pipe frame is fixed to the top surface of the pre-pressurizing shell. An operating rod is arranged in the supporting pipe frame. The top of the operating rod penetrates upwards out of the supporting pipe frame and is provided with an operating head. The bottom of the operating rod extends downwards into the pre-pressurizing shell, and a shifting piece is fixed to the bottom of the operating rod. The upper portion of the shifting piece is vertical, and the lower portion of the shifting piece deflects towards the side away from the valve. A seam is formed in the middle of the shifting rod in the direction of the shifting piece. A sliding block is arranged between the pre-pressurizing spring and the valve. One end of a pull rod is fixed to the sliding block. The other end of the pull rod sequentially penetrates through the pre-pressurizing spring, the baffle and the seam. A protruding block is arranged on the pull rod and located near the side, away from the valve, of the shifting piece. The coarse motion of loosening or tensioning the pre-pressurizing spring is converted into the longitudinal motion of lifting or pressing the operating rod, the overall arrangement is reasonable, operation of aviators is facilitated, and the aviators can autonomously choose to start the pre-pressurizing function or stop the pre-pressurizing function.

Description

technical field [0001] The invention relates to a pre-charging mechanism of an anti-load voltage regulator, in particular to a pre-charging mechanism of an anti-load voltage regulator with a selection function. Background technique [0002] Pilots need to wear anti-G suits to improve positive overload endurance during the flight. The anti-G pressure regulator is an important part of the anti-G suits. It automatically adjusts the air input into the anti-G capsules in the anti-G suits according to the size of the maneuvering overload of the aircraft. pressure. In order to shorten the inflation time of the anti-G suit, before the high maneuvering overload of the aircraft occurs, a lower pressure air is pre-injected into the anti-G capsule in the anti-G suit through the pre-charge mechanism of the anti-G pressure regulator, occupying the capsule cavity, After the occurrence of high maneuvering overload, the anti-G pressure regulator directly inputs air into the anti-G capsule i...

Problems solved by technology

[0003] The current pre-charging mechanism of the anti-gauge pressure regulator is set on the aircraft heading (±X direction), including the pre-charging housing on the anti-gauge pressure regulator and the pre-charging housing in the pre-charging housing. Pressure spring, baffle and valve. The valve is facing the exhaust port of the anti-load pressure regulator. The baffle is fixed. The lower valve intercepts the air leakage between the inner cavity piston of the anti-gauge pressure regulator and the pre-stamping shell, forming a small pressure to complete the pre-stamping; due to the space limitation of the aircraft cockpit, most of the structure of the anti-gage pressure regulator is covered by the instrument cover. The installation space of the pre-charging mechanism of the anti-gauge pressure regulator is small, and it is difficult to install an excessively large operating switch or installation operation in the aircraft heading (±X direction), lateral direction (±Y direction), and longitudinal direction (±Z direction). After the switch, the pilot cannot operate conveniently, so the current pre-charge mechanism of the anti-gauge pressure regulator does not have a switch selection function (the pre-charge spring always presses the valve, and it can only be inflated all the time and cannot be released). The anti-G suit is kept inflated during the whole process from the engine of the aircraft to the start of the flight mission until the completion of the mission and the pilot leaves the cockpit after the plane lands. Although the pre-ramping pressure is low, the pilot is kept pressurized during the entire mission, which will Causes pilot discomfort, especially for multiple consecutive flights
