Description
Technical field
The utility model is related to the parts of lubricating oil pump, and in particular to a kind of safety valve for lubricating oil pump.
Background technology
Gear-type oil pump is the fuel feeding facility of engine lubrication system, mainly by the pump housing, pump cover and in the pump housing
A pair of pitch wheels are constituted, and pump cover is arranged on the pump housing, and when gear-type oil pump works, machine oil is intermeshing
Gear is transported to oil-out from oil inlet, and the oil pressure of oil-out can reach more than ten or even tens MPas, due in the course of work
In, with the increase of machine well cuts, the oil-out of lubricating oil pump forms Partial Blocking sometimes, influences the normal outflow of machine oil,
The oil pressure in the pump housing is gathered increase, often exceed the safe pressure of setting, be that the safe handling of lubricating oil pump causes certain shadow
Ring, therefore, the oil-out in lubricating oil pump is provided with safety valve, when the oil pressure for lubricating oil pump is too high, can with discharge part machine oil,
To reduce the pressure in the pump housing, it is ensured that the safety of lubricating oil pump, but the need for present safety valve can not meet lubricating oil pump, usually
Open in advance, cause pressure in pump to reduce, it is impossible to ensure the normal conveying of machine oil.
Utility model content
To solve the above problems, the utility model proposes a kind of safety valve for lubricating oil pump, the safety valve is arranged on
On the pump housing of the lubricating oil pump, an oil outlet is provided with the pump housing, the safety valve includes valve body, valve body has a circular valve
Chamber, the opening of valve pocket is directed away from the pump housing of the lubricating oil pump, and the bottom of valve pocket opens up the oil-through hole of the connection oil outlet,
Oil-through hole is coaxially disposed with valve pocket, and internal diameter of the internal diameter less than valve pocket of oil-through hole, and one is provided with valve pocket and was resisted against oil
Steel ball on hole, an alignment pin for running through the valve body is provided with one end of the pump housing of the remote lubricating oil pump of valve pocket, in positioning
A spring for pressing steel ball is provided between pin and steel ball；The diameter of the steel ball is more than the internal diameter of oil-through hole and less than valve pocket
Internal diameter, steel ball is in contact towards the inner edge of one end of valve pocket with oil-through hole and forms linear sealing.
Further, in order that the stress of spring is more steady, spring base is provided between spring and alignment pin.
Further, spring base and alignment pin are provided with least one piece adjusting gasket.Bullet can be adjusted using adjusting gasket
The decrement of spring, and then the oil pressure opened the safety-valve is adjusted, make the safety valve in the spring using same model, can be used for
Different lubricating oil pump.
Further, the spring is cylindroid helical-coil compression spring, and preferably the two terminal circle of spring is simultaneously tight and polishes.Cylinder spiral shell
Compression spring is revolved as conventional compression spring, it is in the prior art, many with model, the characteristics of simple in construction, by spring
Two terminal circle and tight and after polishing, spring can be enable to be stablely supported on spring base.
In the utility model, come machine oil in canned pump body by the way of steel ball and oil-through hole are using linear sealing, due to steel
The contact area of ball and oil-through hole is fewer, and the impurity in machine oil is difficult clip between steel ball and oil-through hole, ensure that
The sealing of lubricating oil pump, will not produce the phenomenon opened in advance.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the present utility model.
Embodiment
Embodiment 1：
Refering to Fig. 1,
A kind of safety valve for lubricating oil pump, the safety valve is arranged on the pump housing of the lubricating oil pump, is set on the pump housing
An oil outlet is equipped with, the safety valve includes valve body 16, valve body has a circular valve pocket 18, and the opening of valve pocket is directed away from the machine
The pump housing of oil pump, the bottom of valve pocket opens up the oil-through hole 17 of the connection oil outlet, and oil-through hole 17 is coaxially disposed with valve pocket 18,
And the internal diameter of oil-through hole is less than the internal diameter of valve pocket, a steel ball 11 being resisted against on oil-through hole is provided with valve pocket, in valve pocket
One end of the pump housing away from lubricating oil pump is provided with an alignment pin 15 for running through the valve body, is provided between alignment pin and steel ball
One presses the spring 12 of steel ball；The diameter of the steel ball be more than oil-through hole internal diameter and less than valve pocket internal diameter, steel ball with it is excessively oily
The inner edge of hole towards one end of valve pocket is in contact and forms linear sealing.
In the present embodiment, in order that the stress of spring is more steady, spring base is provided between spring and alignment pin
13.Spring base and alignment pin are provided with least one piece adjusting gasket 14.The decrement of spring can be adjusted using adjusting gasket,
And then the oil pressure opened the safety-valve is adjusted, make the safety valve in the spring using same model, can be used for different machine oil
Pump.
In the present embodiment, the spring is cylindroid helical-coil compression spring, and the two terminal circle of spring simultaneously tightly and is polished.
In the utility model, come machine oil in canned pump body by the way of steel ball and oil-through hole are using linear sealing, due to steel
The contact area of ball and oil-through hole is fewer, and the impurity in machine oil is difficult clip between steel ball and oil-through hole, ensure that
The sealing of lubricating oil pump, will not produce the phenomenon opened in advance.
