Abstract

The invention discloses an aviation pressure refueling adapter, relating to the technical field of aviation refueling. The aviation pressure refueling adapter comprises a pedestal, a valve, a pipe joint, a spring and a sealing ring, wherein the pedestal is of a hollow structure; one end of the pedestal is fixedly connected with the pipe joint to form an accommodation cavity, and the other end of the pedestal is connected with a ground refueling connection nozzle; one end of the valve is provided with an outer conical surface; the other end of the valve is provided with a groove; through holes are formed longitudinally along the side wall of the groove; the valve and the spring are arranged in the accommodation cavity; one end of the spring is in contact with the pipe joint; the other end of the spring is arranged in the groove at one end of the valve; the outer conical surface of the valve is matched with the pedestal in a sealed manner; and the sealing ring is arranged between the match surfaces of the valve and the pedestal. The aviation pressure refueling adapter has the beneficial effects that after the pressure refueling adapter disclosed by the invention is adopted, the refueling for airplanes can change from traditional gravity refueling to pressure refueling; the refueling efficiency is improved; and light and small refueling equipment can be adopted for ground refueling equipment, so that the cost of the refueling equipment is saved.

Description

technical field [0001] The invention relates to the technical field of aviation refueling, in particular to an aviation pressure refueling joint. Background technique [0002] Aircraft refueling methods are divided into two types: gravity refueling and pressure refueling. Gravity refueling is to use the oil's own gravity to refuel. The refueling cap is generally opened on the fuselage. When refueling, the cap needs to be opened. The refueling equipment is simple, but there are the following deficiencies : [0003] (1) Long refueling time, low efficiency, and high labor intensity for maintenance personnel; [0004] (2) The mouth cover is opened on the upper part of the aircraft. When refueling, a ladder is required to climb up the aircraft to refuel. The maneuverability is poor, and it is easy to cause unsafe factors and other deficiencies, and the reliability is low. [0005] (3) In the open type, impurities and water can easily enter the system, causing oil pollution, cau...
