Abstract
The invention discloses a kind of steel ball respirators, including respirator pedestal, respirator top cover and steel ball, respirator top cover is mounted on respirator pedestal, and steel ball is placed in respirator, it is cone cell, and top drilling at the top of reticulated cell respirator top cover that respirator base bottom, which is equipped with,.Integrated level of the present invention is higher, and components are less, small in size, can improve the service performance of hand-operated gear pump using the present invention.
Description
Technical field
The present invention relates to the hydraulic system fuel feeding hand pump fields in aircraft, helicopter, specifically, being a kind of steel ball
Respirator.
Background technique
Hand-operated gear pump in the country's is Hydraulic Elements used in plane hydraulic system at present, and traditional hand-operated gear pump is exhaled
Haustorium is rubber respirator, cuts an openning to reach ventilatory effect on rubber, but this structure can not be inverted in pump
When play the role of seal oil liquid.
Summary of the invention
The purpose of the present invention is to provide a kind of steel ball respirators.
The technical solution for realizing the aim of the invention is as follows: a kind of steel ball respirator, including respirator pedestal, respirator top
Lid and steel ball, respirator top cover are mounted on respirator pedestal, and steel ball is placed in respirator.The respirator base bottom is set
There is reticulated cell.It is cone cell at the top of the respirator top cover, and top is provided with taper hole.
Compared with prior art, the present invention its remarkable advantage: (1) integrated level of the present invention is higher, and components are less, volume
It is small, high reliablity.(2) use space is saved, cost is reduced, use scope is extensive, is easy to be widely applied.
Detailed description of the invention
Attached drawing is the exploded view of steel ball respirator of the present invention.
Specific embodiment
Steel ball type respirator of the present invention uses the principle of hydraulically-controlled one-way valve, pump be inverted when with steel ball by respirator venthole
It seals, reaches sealing function.By steel ball be mounted on bottom be it is netted, top is steel ball when normal work in the respirator of cone cell
It falls on bottom web, air enters fuel tank by tapered top portion aperture, reaches air pressure balance in fuel tank, when fuel tank tilts or is inverted
When, steel ball rolls into cone cell aperture, reaches sealing effect using self weight and hydraulic seal aperture.
The invention is further explained in the following combination with the attached drawings of the specification.
Reference section one-way pressure-limit valve structure of the present invention closes the function open at one end of reaching one-way ventilating using steel ball,
Structure is simple, mainly there is three big component parts: respirator pedestal 1, respirator top cover 2, steel ball 3.Oiling hand pump works normally
In the case of, steel ball is fallen on respirator pedestal, is balanced in oiling hand pump by the mesh on the taper hole and pedestal on top cover
Air pressure；When oiling hand pump is inverted, steel ball is dropped on the taper hole on top cover, and taper hole is blocked, and reaching makes hydraulic oil in fuel tank
With the purpose of external world's barrier.
In conclusion integrated level of the present invention is higher, components are less, small in size, save use space, reduce into
This, high reliablity can improve the service performance of hand-operated gear pump using the present invention, and use scope is extensive, is easy to large area and pushes away
Extensively, usability in particular circumstances is improved.
