Abstract

The invention relates to an oxygen supply pressure adjusting device. The oxygen supply pressure adjusting device comprises a casing, a membrane, a valve base, a valve plate, an adjusting nut, a t-branch pipe and a first spring; three openings of the t-branch pipe are respectively connected with an oxygen supply adjuster, an oxygen mask and the casing; the lower end of the casing is connected with a compensatory waistcoat; the upper end of the valve base is connected with the casing through the membrane; the valve plate is arranged at an outlet at the lower end of the valve base; the adjusting nut is fixed inside the casing; the valve plate is inserted inside the adjusting nut and the valve plate and the adjusting nut are in clearance fit; the first spring is arranged between the valve plate and the adjusting nut; the casing is provided with a pressure relief opening. The oxygen supply pressure adjusting device can simplify an airplane oxygen supply pipeline and reduce pilot burdens under the basis that the high maneuvering characteristic and the high altitude compensatory protection are satisfied.

Description

technical field [0001] The invention relates to oxygen supply equipment for pilots, more specifically, to an oxygen supply pressure regulating device. Background technique [0002] At present, the oxygen masks and compensatory vests used by fighter pilots in our country supply oxygen separately, and each has an independent oxygen supply pipeline. The oxygen supply pipelines of the oxygen mask and the compensation vest are independently controlled, and the oxygen supply pressure of the oxygen mask and the inflation pressure of the compensation vest are adjusted according to the ambient pressure. The arrangement of two sets of oxygen supply pipelines in the prior art complicates the oxygen supply system, increases the burden on the pilot, is easily damaged, and requires high maintenance costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oxygen supply pressure regulating device to simultaneously supply oxyge...
