Description
Technical field
The utility model belongs to mechanical vacuum equipment technical field, is related to a kind of vacuum pump, more particularly to a kind of vacuum pump
In oil return floating ball component.
Background technology
Vacuum pump refers to be obtained to being evacuated by pumping container using machinery, physics, chemically or physically chemical method
The device or equipment of vacuum, for popular, vacuum pump is to improve, produce and maintain true in a certain enclosure space with various methods
Empty device.The effect of vacuum pump is exactly that gas molecule is extracted from vacuum chamber, reduces the indoor gas pressure of vacuum, is allowed to reach
To desired vacuum.Vacuum pump oil return floating ball is also referred to as oil return float ball, its effect be by the effect of the lever force of pedestal,
Rise with the buoyancy of oil level, decline so as to achieving the purpose that oil return, its working principle special as family toilet flush in
Floating ball lever, by oil buoyancy, block or open automatically the oilhole on pedestal.But it usually there will be in fluid micro
Impurity, after long-term use its internal carbon distribution can accumulate in the gap of floating ball component, the fixation to floating ball and pedestal junction
Bar increases frictional force, and floating ball rebound effect can be caused to lose when serious.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of floating ball gyroscopic effects
The oil return floating ball component that can be more preferably effectively increased in the vacuum pump of its service life.
The purpose of this utility model can be realized by following technical proposal：A kind of oil return floating ball component in vacuum pump,
Coordinate including valve pocket, pedestal and up and down molding floating ball, the bottom of the floating ball is provided with the connection for being integrated with formula structure
, axis hole is laterally offered on the connecting seat, and the inside of connecting seat is cavity structure, is matched somebody with somebody in the cavity of the connecting seat
Conjunction is provided with rubber plug, and the both ends that pivot pin and pivot pin are equipped with the rubber plug are rotatably connected in pedestal through axis hole
On, it is characterised in that the bottom gap of the pedestal is equipped with valve pocket, and spool, and spool are provided with the valve pocket
Oil outlet abut against rubber plug bottom, the top of the rubber plug laterally offers one of V-groove.
Oil return floating ball component its technique effect in this vacuum pump is：Oil return floating ball is installed in fuel tank, returning at pump head
Oil pipe will connect the spool communicated therewith, and oil unnecessary in pump head is collected into fuel tank internal, by the buoyancy of oil, block automatically
Or the oilhole on opening pedestal, when fuel tank inner fluid reduces, floating ball, which declines, is at the same time opened spool toward oil by rubber plug
Oiling in case, when fuel tank inner fluid raises, floating ball, which rises, is at the same time closed spool by rubber plug, since oil return floating ball exists
The elastic effect of its rubber plug reduces after long-time use, then hydraulic fluid port can not be blocked when oil level is higher, consequence will cause
Whole oil return circuit can not work normally, so that cause vacuum pump body lubrication inadequate indirectly, or pump housing oil is excessive, and in order to protect
The unimpeded of oil circuit and normal work are held, and obtains stable vacuum, extend the service life of oil return floating ball, the utility model
By laterally opening up one of V-groove at the top of rubber plug, when being stuck in floating ball uphill process, its connecting seat will make rubber
Glue plug inwardly extrudes, and the bottom surface of rubber plug is lifted up, and increases its gyration aperture, so that floating ball reaches designated position.
In oil return floating ball component in a kind of above-mentioned vacuum pump, the angle [alpha] of the V-groove is 17 degree, the V-groove
Depth d be 25 millimeters.
In oil return floating ball component in a kind of above-mentioned vacuum pump, the lower end of the valve pocket offers seal groove.
In oil return floating ball component in a kind of above-mentioned vacuum pump, sealing ring is arranged with the seal groove.
The oil return pipe of valve pocket and vacuum pump is connected by the cooperation of seal groove and sealing ring, effectively increases its sealing
Property, prevent fluid from overflowing.
Compared with prior art, the oil return floating ball component in this vacuum pump is made it have by being improved to rubber plug
Gyroscopic effects are more preferable and the advantages of service life is longer.
