Embodiment Construction

[0017] This embodiment is a brake valve that can meet the braking requirements of the aircraft take-off line, including a housing 1 , a brake pressure reducing valve 2 , an electric valve 7 and a travel switch 8 . The brake pressure reducing valve 2 and the electric valve 7 share a housing 1, which are respectively installed in the brake pressure reducing valve chamber and the electric valve chamber in the housing 1, so that the housing 1 is both an assembly frame and a brake valve. An integral part of pressure reducing valve 2 and electric valve 7. The brake pressure reducing valve chamber and the electric valve chamber communicate with each other through the oil passage on the housing: one end of the oil passage communicates with the brake window of the brake pressure relief valve 2, and the other end communicates with the first brake window of the electric valve 7. The oil inlet window is connected.

[0018] There are four hydraulic ports on the casing 1, which are the oil...

Abstract

The invention discloses a brake valve capable of meeting the brake requirement of the take-off line of a plane. A brake reducing valve and an electric valve are installed in a brake reducing valve cavity and an electric valve cavity in a shell respectively. The brake reducing valve cavity and the electric valve cavity are communicated through an oil path on the shell. A travel switch is installed at the position, near the brake reducing valve, of the shell. The brake valve of the plane is installed near a pedal mechanism under a bottom plate of a cockpit of the plane and is operated in the mode that a driver steps a brake pedal to output needed brake pressure, so that normal braking or take-off line braking is realized. A brake system is simplified, and the reliability and safety of the brake system of the plane are improved. Independent elements and accessories are integrated, and designed and manufactured modularly, so that use and maintenance are convenient.

Description

technical field [0001] The invention relates to an aircraft wheel hydraulic braking system, specifically a brake valve that meets the high braking pressure requirements of the aircraft take-off line, and more specifically a brake valve that can directly output the oil supply pressure without decompression when the aircraft takes off line braking. aircraft brake valve. Background technique [0002] The brake valve is the basic component of the aircraft brake system. This brake valve is actually a variable pressure reducer. During normal braking, the driver usually manipulates the brake valve through the pedal mechanism to reduce the high-pressure hydraulic pressure provided by the hydraulic brake system supply source to the required brake pressure, and output it to the wheel brake device for braking. Due to the increase of aircraft take-off thrust, especially the use of carbon brakes, the brake pressure required for take-off line braking has doubled (some have exceeded twic...
