Description
Technical field
The present invention relates to quantitatively go out oil dispenser, specifically a kind of oil dripping valve.
Background technique
The device of existing control flow of lubrication generally has positive displacement distributor and two kinds in opposing formula distributor.Wherein resist the ratio that the is typically joint of formula distributor, control flow of lubrication by size and the shape of setting the logical oily cross section of inside cavity, but error is bigger, the error of the ratio joint flow ubiquity of same specification ± more than 20%.And the general flow of positive displacement distributor is bigger, and flow error is also not little.
Summary of the invention
The oil dripping valve that the purpose of this invention is to provide a kind of accurate control flow of lubrication.
The present invention will solve be existing control flow of lubrication go out the bigger problem of oil dispenser oil pump capacity error.
Technological scheme of the present invention is: it comprises valve body, valve pocket left side at valve body is provided with spring lock block, non-return spring, non-return ball seat, reverse stopping ball, non-return ball seat is connected with non-return spring, the other end of non-return spring withstands on the spring lock block respectively, non-return ball seat right side is a reverse stopping ball, be provided with on piston spring, steel ball and plunger, the plunger on the right side of the valve pocket of valve body and be connected with piston spring, the left side of plunger is a steel ball, right-hand member at valve body is provided with filler opening, the filler opening place is provided with the oil-feed filter screen, and the outside of valve body is with seal ring.
Advantage of the present invention is: be applicable to the occasion that need accurately control lubricants capacity, select the oil dripping valve of desired flow according to the actual demand of lubricating point.The present invention can accurately be controlled at only numerical value with flow of lubrication, can guarantee the sufficient lubrication of lubricating point energy, can avoid the waste of lubricant oil again.
Description of drawings
Fig. 1 is the structural representation of oil dripping valve of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in the figure, the present invention includes valve body 11, valve pocket left side at valve body 11 is provided with spring lock block 1, non-return spring 2, non-return ball seat 3, reverse stopping ball 4, non-return ball seat 3 is connected with non-return spring 2, the other end of non-return spring 2 withstands on respectively on the spring lock block 1, non-return ball seat 3 right sides are reverse stopping ball 4, be provided with on piston spring 5, steel ball 6 and plunger 7, the plunger 7 on the right side of the valve pocket of valve body 11 and be connected with piston spring 5, the left side of plunger 7 is a steel ball 6, right-hand member at valve body 11 is provided with filler opening 8, filler opening 8 places are provided with oil-feed filter screen 9, and the outside of valve body 11 is with seal ring 10.
The present invention is two-way non-return structure, and the valve pocket in the middle of its two-way non-return structure is for holding oily space, and when the volume that holds oily space was determined, oil dripping valve flow was just determined.As flow is 0.01ml/ time, 0.03ml/ time, the oil dripping valve of the inferior different size of 0.05ml/.
Working principle of the present invention is: the structure of oil dripping valve of the present invention constitutes a forward one-way valve and a reverse one-way valve.When not having fluid pressure in the pipeline, the oil dripping valve be in position shown in Figure 1, saving the lubricant oil of a constant volume this moment in the cavity space between plunger, steel ball and reverse stopping ball.
When board during to the oiling of oil dripping valve, the spring that the pressure of fluid overcomes piston spring in the pipeline is tried hard to recommend the plunger of moving forward one-way valve; The lubricant oil that the action meeting that plunger moves will be saved before plunger promotes, and opens reverse stopping ball and discharges the oil dripping valve by reverse one-way valve; Plunger continues to move, and promotes the center hole that steel ball is blocked valve, makes valve body be in non-return state, and the lubricant oil that Lubricators is got is stoped by the oil dripping valve.
When board stopped to buy oil, fluid pressure disappeared in the pipeline, and the piston spring in the forward one-way valve promotes plunger return; At this moment, oppositely the one-way valve reverse stopping ball is blocked oil dripping valve center hole under non-return spring action, plays the effect that prevents that lubricant oil from refluxing; And the oil storage cavity body space between reverse stopping ball and the plunger can produce suction because fluid pressure is too small, the fluid in the pipeline is sucked in this space by the gap between plunger and the valve body vestibule save.
Accurately control oil dripping valve flow by control plunger movement distance with the cross-sectional sizes of plunger.
