Detailed description of the invention
For making object of the invention process, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the present invention's part embodiment, instead of whole embodiments.Be exemplary type below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creation type work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
In describing the invention, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limiting the scope of the invention can not be interpreted as.
As depicted in figs. 1 and 2, a kind of valve arrangement according to draught head air inlet of the present invention, comprises covering 1, valve shell 2, valve 3 and slide bar 4, and described covering 1 is provided with opening; Described valve shell 2 is provided with cavity volume and is provided with multiple vent window in chamber wall, and valve shell 2 is placed in covering 1 opening part, and the sectional area parallel with covering 1 of described cavity volume is greater than described aperture area, and described valve shell 2 is tightly connected with covering 1; Described slide bar 4 is arranged at the center of described valve shell 2 cavity volume inside and is fixedly connected with valve shell 2, and described slide bar 4 is vertical with covering 1; Described valve 3 is discoid and centre is provided with through hole, and valve 3 plan area is placed between the sectional area of cavity volume and aperture area, and valve 3 is placed in the cavity volume of valve shell 2, and described slide bar 4 passes perpendicularly through the through hole of valve 3, slide bar 4 and valve 3 relative sliding.
It is pointed out that slide bar 4 is placed in the center of the inner chamber of the valve shell 2 of hat.
It is pointed out that the quantity of vent window is 4.
It is pointed out that and valve 3 is also provided with multiple strengthening rib 31, strengthening rib 31 extends to through hole direction from the outer circular edge of discoid valve 3, and strengthening rib 31 can increase the stability of plate-like valve 3.
It is pointed out that the quantity of strengthening rib 31 is 6.
The application following (as shown in Figure 3 and Figure 4) of concrete valve arrangement of the present invention, the entrance of engine bay ventilation cooling-air flow has two places: a place is that engine front cover circle time flows to mouth, is the form of plate-like valve; Another place is the plate-like valve form under ventral.
When the gas turbine starter work of driving engine, form certain negative pressure in machinery space, make valve 3 ground air inlet open, cooling-air flow is for starter air inlet.When the engine operates, in driving engine nozzles with injector suction cabin, air-flow makes to keep negative pressure in cabin, and when ground and low-speed operations, valve 3 is in open mode; And when cabin internal pressure is greater than inlet pressure, valve 3 is just closed automatically, makes air in cabin not flow backwards and enters inlet channel.The cooling-air flow entered from valve 3, under the effect of driving engine nozzles with injector, cools, finally from nozzles with injector discharge machine the structure in machinery space and annex etc.When airflight reaches certain flying speed, inlet channel internal pressure raise, under differential pressure action, valve 3 is in an open position, and pressure in engine room is constantly increased, when reach cabin internal pressure be greater than out of my cabin air pressure time, under differential pressure action, valve 3 is closed.Cooling-air flow, under the effect of nozzles with injector and inlet pressure, enters machinery space from valve 3, cools, finally from nozzles with injector discharge machine the structure in machinery space and annex etc.
The admission port of valve 3 is exactly poor according to fuselage machinery space inner and outer air pressure, and valve 3 moves up and down at slide bar 4, realizes to the object of machinery space bleed.Valve 3 is attached on the covering 1 at lid place under self gravitation effect at ordinary times, is closed condition; When engines ground and nonchannel flow operation, be negative pressure in machinery space, outside fuselage, air pressure backs down valve 3, and valve 3 is in opening, and air-flow dispels the heat to machinery space bleed through valve shell 2 vent window; After flying speed exceedes certain value, in driving engine, cabin is malleation, and promote valve 3 and push up covering 1 opening, valve 3 is in closed condition.
A kind of valve arrangement according to draught head air inlet of the present invention, can avoid structurally designing complicated control mechanism, the principle of Appropriate application draught head, structural arrangement is allowed to simplify, adopt the device of structure of the present invention, structural machinability is good, alleviates structural weight, improve reliability of structure, its maintainability and good economy performance.
The above; be only optimum detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
