Description
Technical Field
The utility model belongs to the technical field of the aircraft debugging, a machine oil absorption pressure valve adjustment resetting means is related to, mainly through hand-held type adjustment frock, oil absorption valve and pressure valve adjustment work that resets on high-efficient, the high-quality completion aircraft machine.
Background
The pressure supply of the aircraft hydraulic system is mainly divided into the following two forms:
(1) When the aircraft is in a flight stage, the pressure supply of the hydraulic system is realized by hydraulic oil in an oil tank through a hydraulic plunger pump;
(2) When the airplane is in a ground debugging stage, the hydraulic system supplies pressure to the airplane by connecting the onboard hydraulic system with a ground pump source, and the ground pump source establishes required pressure to supply the airplane hydraulic system to work.
The hydraulic system is used as the most important functional system on the airplane, the retraction and the extension of landing gears on the airplane, the deflection of each control surface, the work of an oil receiving device and the like are all completed by depending on the hydraulic system. The pressure valve and the oil suction valve are butt joint parts of a hydraulic system and a ground pump source, and have the same structure, and the difference is that the through holes are different in size. Therefore, the working performance of the oil (pressure) suction valve on the aircraft is good and bad, which has important significance for the debugging work of the aircraft hydraulic system.
When the hydraulic system of the airplane is connected with the ground pump source, the end of a ground pump source hose is connected with the port position of an oil (pressure) suction valve on the airplane, the end of the hose forces the one-way valve to leave the valve seat, the one-way valve is in the open position, and hydraulic working fluid circulates between the hydraulic system and the ground pump source through the oil (pressure) suction valve on the airplane; when the hose is detached, the check valve is reset to the valve seat under the action of the spring, and at the moment, the oil circuit of the airplane and the ground pump source is disconnected.
However, due to the influence of the deformation of the spring, the one-way valve cannot be completely reset, namely, a deviation gap is formed between the one-way valve and the valve seat, and the hydraulic working fluid leakage phenomenon is easy to occur. If the on-board oil (pressure) absorption valve is returned to the factory for repair, complex work such as engine disassembly is needed, and the delivery cycle of the airplane is affected. The existing solution needs the operator to use a flat-nose pliers to pinch the end of the check valve for adjustment and restoration, but the operation mainly has the following defects:
(1) When the flat nose pliers hold the end of the one-way valve to adjust and reset, the surface of the end of the one-way valve is easy to have micro scratches and indentations;
(2) In the adjusting process, because the length of the end of the one-way valve is too small, the operating space is insufficient, the flat-nose pliers frequently slip, and the adjusting efficiency is extremely low;
(3) Because of the influence of system pressure, the hydraulic pressure working fluid spun phenomenon appears easily in the adjustment process to the operator, not only pollutes the surrounding environment, if the operator dodges untimely, also can be splashed to important body positions such as face by hydraulic pressure working fluid, and to a great extent threatens operator's life safety.
