Therefore, the purpose of this utility model is: design a kind of plunger-type quantitative distributor, make it have excellent sealing performance, and can finish the task to the rationing lubricant oil of equipment effectively.
The utility model adopts and quantitatively is being provided with an one-way valve 4 of being made up of O-ring seals 9 in the distributor body between plunger and the bipyramid cutting ferrule, the close circle 9 of O shape is arranged in the pipeline that oil outlet tube communicates with distributor chamber, the communicate interior ring of O-ring seals 9 of distributor chamber, one-way valve and quantitatively on the surface of contact of plunger or between be provided with a sealing surface of forming by elastic material, sealing surface can be O-ring seals, and it is positioned on the one-way valve of distributor chamber one side, also can be the rubber boss or the resilient seal surface that are positioned on the quantitative plunger, the outward edge of the inward flange clamping O-ring seals of gland.The said structure design has realized the purpose of this utility model.
Great advantage of the present utility model is: can finish the rationing lubricant oil to equipment effectively, distributor has excellent sealing performance simultaneously.
Below in conjunction with Figure of description and embodiment structure of the present utility model is further described.
Fig. 1 is the utility model schematic representation.
With iron distributor body 2 of the present utility model, oil extraction joint 5, the hollow screw 6 done.Make round barrel shape distributor chamber 12 in distributor, distributor chamber one end and oil inlet pipe 13 communicate.The quantitative plunger 1 that its center, top is cone shape is positioned at distributor chamber, its circular cone dignity and 13 pairs of direction settings of oil inlet pipe, quantitatively between plunger and the distributor chamber inwall micro-gap is arranged, its role is to make quantitative plunger in distributor chamber, to move up and down, make the lubricant oil that enters oil pressure pipe flow into distributor chamber 12 simultaneously along this gap.A quantitative face closure oil inlet pipe of plunger, another side is provided with spring 11, and in order to pushing down quantitative plunger, circular shape gland 3 is fixed on spring in the distributor chamber.One-way valve 4 is positioned at gland 3 upper ends, one-way valve is provided with a groove towards an end of distributor chamber, the inward flange that is provided with an O-ring seals 10, gland in it blocks the outward edge of O-ring seals 10, obviously this O-ring seals 10 is positioned at connecing on the energy face of one-way valve and quantitative plunger 1, promptly when quantitative plunger rises, but the cone apical grafting of its front end is on the interior ring of O-ring seals.
One-way valve 4 in the distributor body between quantitative plunger and bipyramid cutting ferrule is made up of O-ring seals 9, and O-ring seals 9 is arranged in the pipeline that oil outlet tube 7 communicates with distributor chamber 12, and one-way sealing oil outlet tube 7 is to the pipeline of distributor chamber.The communicate interior ring of O-ring seals 9 of distributor chamber, oil outlet tube 7 communicates with the outer shroud of O-ring seals 9.Fixedly the inner of one-way valve and oil outlet tube 7 on distributor body, will compress at the bipyramid cutting ferrule 8 on the oil outlet tube outer wall in order to sealing oil outlet tube outer wall with oil extraction 5 with hollow screw 6.
During use, drive the lubricant oil of the high pressure of supplying with from oil inlet pipe 13 by oil pressure pump, entering distributor chamber 12 will push away on the quantitative plunger 1, when quantitatively plunger 1 is up, original quantitative lubricating oil in the distributor chamber 12 is pressed to the interior ring of O-ring seals 9 from the outlet of one-way valve 4, O-ring seals 9 pressurizeds outwards expand and open check valve, lubricant oil flows into oil outlet tube 7 needs oil oil to the equipment friction through oil outlet tube surface, when quantitative plunger 1 is up, spring 11 shrinks, the cone apical grafting of plunger front end is on the interior ring of O-ring seals 10 time, it expands, and the sealing distributor chamber leads to the pipeline of oil outlet tube 7, finishes quantitative fuel feeding.After oil pressure pump cuts out, quantitatively plunger 1 loses pressure, under the effect of spring 11, fall bottom after rise, meanwhile, be positioned at the also pinch confinement oil outlet tube loop of O-ring seals 9 on the one-way valve to distributor chamber, in this falling process, quantitatively plunger causes vacuum in the distributor chamber between itself and the one-way valve, and the oil between quantitative plunger and oil inlet pipe 13 then flows in the distributor chamber of vacuum along the quantitative gap between plunger and the distributor chamber inwall, in order to again to equipment rationing notes lubricating oil.
