Cleaning device for non-decomposable one-way valve of airplane and cleaning method of cleaning device

Abstract

The invention relates to the technical field of airplane mechanical accessory repairing processes, in particular to a cleaning device for a non-decomposable one-way valve of an airplane and a cleaningmethod of the cleaning device. The cleaning device comprises an adapter, a mandrel and a handle, the adapter is connected with the outline of the end face of the one-way valve in a matched mode, themandrel is arranged in the adapter and used for jacking the one-way valve to conduct reverse pressurization flushing, and the handle is arranged at the end of the mandrel and facilitates force application. The cleaning method comprises the following specific cleaning steps that S1, the adapter is designed according to the structural form and the working principle of the one-way valve; S2, the one-way valve is installed on the adapter after a rubber ring is installed on the one-way valve; S3, the handle is rotated to enable the mandrel to eject a valve body of the one-way valve to be opened until the valve body is opened to the maximum degree; and S4, hydraulic pressure is supplied from the one-way valve, oil is returned from a filler neck of the adapter, pressure flushing is conducted, andthe one-way valve is jacked open through the mandrel, so that the reverse pressure flushing is achieved, the problem of cleaning of residual rubber foreign matters between the valve body of the non-decomposable one-way valve and a shell is solved, the rapidness and effectiveness are achieved, and the product scrapping is avoided.

Description

technical field [0001] The invention relates to the technical field of aircraft mechanical accessory repair technology, in particular to a cleaning device and a cleaning method for an aircraft non-decomposable one-way valve. Background technique [0002] Non-decomposable spherical check valves such as figure 1 As shown, the number 11 is the shell, the number 12 is the spring, the number 13 is the bracket, and the number 14 is the oil port of the valve, which is installed on the oil return port of a solenoid valve of the aircraft, and is used to connect the solenoid valve to the oil return line of the hydraulic system. , to prevent the pressure pulsation of the oil return line from affecting the reliable operation of the solenoid valve. When the one-way valve is manufactured, after the one-way valve, the spring and the bracket are installed in the housing, the housing is closed and fixed. During the use of the one-way valve, foreign matter such as rubber often remains betwe...

AI Technical Summary

Problems solved by technology

During the use of the one-way valve, foreign matter such as rubber often remains between the valve and the housing, resulting in poor reset of the valve.

Since the one-way valve is formed at one time during manufacture, it cannot be cleaned by disassembling the one-way valve

When the foreign matter is larger than the oil hole of the valve, the normal cleaning method cannot effectively remove the foreign matter due to its elasticity and the small opening between the valve and the housing. Therefore, an effective, convenient and quick cleaning device and method are needed to solve this problem
