Abstract

The invention belongs to the technical field of fuel injection and relates to a fuel injection method for an oil tank with an elastic bag. The oil tank is filled with fuel, gas in the elastic bag is exhausted, then fuel injection to the oil tank with the elastic bag is achieved through the method that the elastic bag is inflated with a certain amount of inert gas which serves as a preserved gas cushion, after being preserved, the gas cushion can ensure that after the fuel is injected, in the long-term storage process of the oil tank, pressure in the oil tank is adjusted through a safety valve connected with the elastic bag along with variation of environment temperature, namely, when the temperature of the oil tank is raised, the pressure reaches a threshold of the safety valve, and the safety valve automatically exhausts the gas in the gas cushion to keep pressure in the oil tank stable, so that influence of variation of the environment temperature on the pressure inside the oil tank can be overcome.

Description

technical field [0001] The invention relates to the technical field of fuel filling, in particular to a fuel filling method for a fuel tank containing an elastic bag. Background technique [0002] Fuel filling is an essential process for providing fuel to the power system of the missile before flight. Depending on the structure of the fuel tank, the method of fueling the missile is also different. According to the difference in the internal structure of the fuel tank, it is divided into a fuel tank with an elastic bag and a fuel tank without an elastic bag. There is currently no method for refueling tanks containing elastic bags. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a highly reliable fuel filling method for a fuel tank containing an elastic bag that can overcome the influence of ambient temperature changes on the internal pressure of the fuel tank. ...
