Abstract
The utility model discloses a quantitative distributor in a lubrication system. A vertical cavity and a horizontal cavity are arranged inside a casing; a crescent hole communicated with the two cavities is arranged under the vertical cavity; a spring sleeve, an oil supply spring and an oil storage piston are arranged successively in the vertical cavity from up to down; an oil storage chamber is positioned in the lower part of the vertical cavity; the left end of the horizontal cavity is communicated with an oil inlet of a sucker; a check valve and an oil delivery joint of a sleeve valve seat are arranged from left to right; a cone spring is sleeved on the left order panel of a valve seat arranged at one end of the check valve cone; the right end of the check valve is matched with an oil outlet in the oil delivery joint. The oil outlet is closed by right level end face at oil storage working situation; a bowl shaped lip is closely matched with a horizontal valve hole. The working process of the utility model: oil storage is first and oil delivery is second; the sealing reliability of the check valve can not be considered when the oil pump is not working. The utility model has the advantages of correct quantitative oil supply, reliable and stable working property.
Description
Affiliated technical field
The utility model relates to the component of lubriator or lubrication system, particularly relates to a kind of quantitative distributor of lubrication system.
Background technique
The quantitative distributor of lubrication system is the lubricant grease accurate quantification with main oil pipe, and the grease of varying number is input to the critical component of each lubricated node.Problems such as the quantitative distributor kind of at present relevant lubrication system is a lot, but in actual use, all exists sealability unreliable to some extent, and is quantitatively inaccurate.Main cause is: its working principle of traditional quantitative distributor is the oil storage again of first fuel feeding, after the oil storage operating mode finishes, one long rest stage is arranged, during this period of time, because the sealability of one-way valve is unreliable, cause part oil to reflux, reduced fuel delivery, cause the life-span of mechanical parts to descend easily lubricated node.
Summary of the invention
The purpose of this utility model is for overcoming the deficiency of prior art, and a kind of reliable working performance, stable is provided, quantitatively fuel feeding a kind of quantitative distributor of lubrication system accurately.
The technical solution of the utility model is: comprise spring press-cover, fuel feeding spring, oil storage plunger, distributor body, delivery connection, safety check, valve seat, taper spring; An one vertical vestibule and a horizontal vestibule arranged in the distributor body, and vertically the below of vestibule has a crescent shape through hole, is communicated with two vestibules; Vertically vestibule is equipped with spring press-cover, fuel feeding spring, oil storage plunger from top to bottom successively, and vertically the vestibule lower end is a shoe cream room; Horizontal vestibule left end communicates with the filler opening of oil inlet pipe, safety check, the delivery connection of overcoat valve seat from left to right are housed, be contained on the valve seat left side terrace of the cylindrical end of safety check and be with taper spring, safety check bowl-type lip limit can with horizontal valve opening close fit, can fit with the oil outlet end face in the middle of the delivery connection in the check valve spool right side.
The utility model is compared with background technique, and the useful effect that has is: it is when the oil storage operating mode, and the right planar end surface of safety check can seal oil outlet; When fuel-displaced operating mode, safety check bowl-type lip limit open and with horizontal vestibule close fit, realize the non-return sealing function.The oil pump rest stage needn't be considered the reliability of check valve seal, and quantitatively fuel feeding is accurate, and oil pump capacity can be controlled as required, has reliable working performance, stable advantage.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of safety check.
Among the figure: 1 spring press-cover, 2 " O " RunddichtringO, 3 fuel feeding springs, 4 oil storage plungers, 5 " O " RunddichtringO, 6 distributor bodies, 7 oil outlets, 8 delivery connections, 9 " O " RunddichtringO, 10 safety check, 11 valve seats, 12 taper springs, 13 filler openings.
Embodiment
Shown in Fig. 1, Fig. 2 a, Fig. 2 b, the utility model comprises spring press-cover 1, fuel feeding spring 3, oil storage plunger 4, distributor body 6, delivery connection 8, safety check 10, valve seat 11, taper spring 12.An one vertical vestibule and a horizontal vestibule arranged in the distributor body 6, and vertically the below of vestibule has a crescent shape through hole, is communicated with two vestibules; Vertically vestibule is equipped with spring press-cover 1, fuel feeding spring 3, oil storage plunger 4 from top to bottom successively, and vertically the vestibule lower end is a shoe cream room, outside spring press-cover 1 and the oil storage plunger 4, " O " RunddichtringO 2, " O " RunddichtringO 5 is housed respectively; Horizontal vestibule left end communicates with working connection, safety check 10, the delivery connection 8 of overcoat valve seat 11 from left to right are housed, be contained on the valve seat 11 left side terraces of safety check 10 cylindrical ends and be with taper spring 12, safety check 10 bowl-type lip limits can with horizontal valve opening close fit, can fit with the oil outlet end face in the middle of the delivery connection 8 in safety check 10 spool right sides; " O " RunddichtringO 9 is housed on the delivery connection 8.
Said safety check 10 its right-hand members are that bowl-type, left end are columniform seal ring.
Vertical vestibule of the present utility model lower end is a shoe cream room, and the axial length of spring press-cover defines plunger stroke, thereby has determined the population size of oil pump capacity; The interior hole depth of spring press-cover has determined spring by precompressed degree, and its depth size is relevant with the grease pressure after the oil storage.Horizontal vestibule is stepped cylindrical hole, and the left end aperture communicates with the working connection oilhole; The spool of safety check is made by senior oil-resistant rubber material, and left end is embedded in the valve seat, and valve seat is supported in the horizontal vestibule by taper spring; Right-hand member is a bowl ring, plays one-way valve, and its planar end surface can be fitted with delivery connection; Have oil outlet in the middle of the delivery connection.When the oil storage operating mode, the right planar end surface of safety check can seal oil outlet; When fuel-displaced operating mode, its bowl-type lip limit open and with horizontal vestibule close fit, realize the non-return sealing function.
Working principle of the present utility model is: when oil pump during to the quantitative distributor fuel feeding of lubrication system, under the oil pressure effect, the planar end surface of check valve spool tightly blocks the oil outlet of delivery connection, grease from filler opening in safety check enters the distributor shoe cream room, in the fluid input cavity, the oil storage plunger rises, and promotes the energy storage of fuel feeding length of spring compressed in oil storage; When oil pump quits work, after the working connection off-load, the pressure reduction of shoe cream room and working connection promotes safety check and moves to left, close filler opening, open oil outlet, shoe cream room is communicated with oil outlet, the fuel feeding spring releases energy, and makes the chamber inner fluid inject each lubricated node from oil outlet through nylon tube under certain pressure.In addition,, determine plunger stroke, the axial length of setting spring gland and spring precompressed degree according to the need oil mass size of actual lubricating point.
