Abstract
The present invention relates to a kind of Fuel Bleed Valves, including valve seat, valve deck, bushing, spring, the valve seat is hollow cylinder, internal engagement installs bushing, bushing is hollow cylindrical, it is disposed with the step coordinated with valve seat top and the circular ring shape position of valve seat inner hole, the fuel-displaced position for being provided with uniformly distributed oil outlet, spring mountings position and spring base from top to bottom, spring is mounted at spring mountings position, screw thread is provided in valve seat lower outer diameter, valve deck is by being threadably mounted at valve seat lower part.The present invention is a kind of Fuel Bleed Valve with self-locking structure, compared to the Fuel Bleed Valve of single layer sealing structure, this structure can effectively avoid the occurrence of leading to lubrication leakage because of seal failure, the structure that spring controls inner liner ensures that lubricating oil sampling amount is more accurate, and effectively avoids that there is a situation where lubrication leakages.
Description
Technical field
The present invention relates to a kind of Fuel Bleed Valves, ensure the requirement of draining the oil of motor oil, and have good sealing performance.
Background technology
In order to monitor the working condition of aero-engine lubricating system, it is often necessary to start to carry out lubricating oil in lubricating system
Sampling.Meanwhile when being performed overhauling and maintenance to aero-engine, it is also desirable to be vented engine interior lubricating oil.To meet engine
Lubricating oil drain the oil require usually engine mainly form attachment drain the oil or sample tap be arranged Fuel Bleed Valve.And it current drains the oil
Valve is mostly single layer sealing structure, and valve is opened when draining the oil, and the release of lubricating oil is uncontrollable, and after engine long time service easily
Seal failure is caused to make lubrication leakage.
Invention content
The purpose of the present invention is designs to provide a kind of Fuel Bleed Valve, and process control of draining the oil may be implemented, and effectively avoid because
Lubricating oil leakage problem caused by seal failure.
The technical scheme is that Fuel Bleed Valve includes valve seat, valve deck, bushing, spring, the valve seat is hollow
Cylinder is mounted on the shell of lubricating oil pond, and top is extend into lubricating oil pond, and internal engagement installs bushing, and bushing is hollow circuit cylinder
Shape is disposed with the circular ring shape position of the step coordinated with valve seat top and valve seat inner hole, is provided with from top to bottom
Fuel-displaced position, spring mountings position and the spring base of cloth oil outlet, spring are mounted at spring mountings position, and upper end is pressed in valve
On seat, lower end is pressed on the spring base of bushing, screw thread is provided in valve seat lower outer diameter, valve deck is by being threadably mounted under valve seat
Portion；It is provided with fluid sealant between the cooperation position of the bushing and valve deck, valve seat and valve deck, between valve seat and lubricating oil pond shell
Circle.
In the use of the present invention, under normal circumstances, bushing top is contacted with valve seat, lubricating oil can not discharge in oil sump；
When needing to put lubricating oil, valve deck is backed out first, then jacks up bushing from bottom to top, bushing overcomes the elastic force of spring, to cunning
Movement in oil sump, when the fuel-displaced position on bushing top enters in lubricating oil pond, lubricating oil will pass through the oil outlet at fuel-displaced position
Bush inside is entered, and is flowed out from lower part by bush inside；When that need not drain the oil, the power for acting on bushing is cancelled, is served as a contrast
It is sleeved under the elastic force effect of spring, moves downward, fuel-displaced position drops in valve seat, and oil outlet is blocked, and process of draining the oil stops.
The present invention is a kind of Fuel Bleed Valve with self-locking structure, compared to the Fuel Bleed Valve of single layer sealing structure this structure can effectively avoid because
Seal failure leads to the occurrence of lubrication leakage.Meanwhile the structure of spring control inner liner ensures lubricating oil sampling amount more
Precisely, and effectively avoid that there is a situation where lubrication leakages.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
As shown, Fuel Bleed Valve includes valve seat 1, valve deck 2, bushing 3, spring 4, the valve seat 1 is hollow cylinder
Shape is mounted on the shell of lubricating oil pond, and top is extend into lubricating oil pond, and internal engagement installs bushing 3, and bushing 3 is hollow cylindrical,
It is disposed with the circular ring shape position of the step coordinated with 1 top of valve seat and 1 inner hole of valve seat from top to bottom, is provided with
Fuel-displaced position, 4 installation position of spring and the spring base of cloth oil outlet 5, spring 4 are mounted at spring mountings position, upper side pressure
On valve seat 1, lower end is pressed on the spring base of bushing 3, and screw thread is provided in 1 lower outer diameter of valve seat, and valve deck 2 is installed by screw thread
In 1 lower part of valve seat；Between the cooperation position of the bushing 3 and valve deck 2, valve seat 1 and valve deck 2, valve seat 1 and lubricating oil pond shell it
Between be provided with sealing rubber ring 6.
