Description
Technical field
The present invention relates to a kind of oilier, especially a kind of valve-type oil feeder that is used for supplying lubricating oil fat.
Background technique
The normal conveying of lubricant grease and supply with very importantly in the lubrication system, particularly the key position of main equipment more needs the normal feed of lubricant grease.For guaranteeing the accurately normal feed of lubricant grease, the existing centralized lubrications that adopt more.At present, centralized lubrication is commonly used lubricating systems such as single line, two-wire, oil gas, and its main components and parts are single-line type oilier, two-wire system oilier, laddering oilier etc.But in actual applications, no matter be single-line type, two-wire system or laddering oilier, all can not carry out STOCHASTIC CONTROL, require accurately to calculate the grease amount of every of system, be difficult for adjusting in actual the use, and the lubrication interval of every of system must be identical in when design; There is the little defective of Applicable scope in the single-line type oilier, is only applicable to that the viscosity grade is low, the fluid of good fluidity, and fluid, the semifluid medium of or mobile difference high for the viscosity grade then can't carry out normal feed; And the structure more complicated of two-wire system oilier and laddering oilier, requirement on machining accuracy height, rate of fault height in the use; The parallel alternately fuel feeding of necessary two main lines of two-wire system oilier, the pipeline complexity; In a single day break down during laddering oilier is used, accurately difficulty is overhauled in failure judgement point position.
Summary of the invention
The present invention by experimental study, provides a kind of novel valve-type oil feeder in order to solve problem and the defective that the grease supply exists in the existing centralized lubrication system, it is simple in structure, and reliable operation is safeguarded easily, applied widely, can satisfy the difference of centralized lubrication system each point and lubricate needs.
Technological scheme of the present invention is as follows:
This valve-type oil feeder comprises oil supply body, spool and piston, and the oil supply body contains valve pocket and piston cavity, and valve pocket is established a filler opening and two outlets; Piston cavity piston one side is an oil suction chamber, is communicated with valve pocket one outlet, and the piston opposite side is communicated with another outlet of valve pocket for going out oil pocket, goes out oil pocket and sets out hydraulic fluid port; Spool reciprocatingly slides in valve pocket vertically, is provided with circular groove, or is provided with circular groove, and is provided with oil through, and this oil through is to be made of axial bore is communicated with outer side wall with it radial hole; Establish reposition element on the valve core piston.
After driving the spool slip, valve pocket and spool enter the working position, filler opening is connected with the circular groove of an outlet by spool, end with another outlet, at this moment the lubricant grease of filler opening enters the oil suction chamber of piston one side by the circular groove of spool, the promotion piston moves, the compression reposition element, and the lubricant grease that goes out in the oil pocket enters pipeline to the operation point by oil outlet; Driving stops valve core reset, be in stop position, filler opening and two outlets all end, two outlets are connected by the circular groove or the oil through of spool, make the oil suction chamber of piston both sides and go out oil pocket and connect, reposition element resets, and promotes piston reverses direction and moves, and the lubricant grease of oil suction chamber enters out oil pocket by the circular groove of spool or two outlets of oil through connection.
Spool can by electronic, surge, pneumatic, motor-driven, manual or Electromagnetic Drive slides in valve pocket.
Piston or oil supply body can be provided with separately to oil controller and detection device.
This oilier is applicable to the lubricant grease in various different pressures, the viscosity scope.
This valve-type oil feeder, simple in structure, reliable operation, safeguard easily, applied widely, be provided with to behind oil controller and the detection device, can adjust at random each lubricating point grease delivery volume, lubrication interval to every is set at random, can satisfy the lubricated needs of difference of centralized lubrication system each point, has a extensive future.

Embodiment
Introduce embodiments of the invention below in conjunction with accompanying drawing.
As shown in the figure, this valve-type oil feeder mainly is made up of oil supply body 1, spool 2 and piston 5 etc.
The structure of spool 2 has two kinds of form: Fig. 1, spool 2 shown in Figure 2 to be provided with circular groove 2a, and when spool 2 was in the working position, circular groove 2a was communicated with oil inlet P and outlet A, and two outlet A, B then end; When spool 2 was in stop position, circular groove 2a then was communicated with two outlet A, B, and oil inlet P is ended with outlet A.
Fig. 3, spool 2 shown in Figure 4 and are provided with the oil through 2b that can be communicated with two outlet A, B except that being provided with circular groove 2a, oil through 2b is made of axial bore is communicated with outer side wall with it radial hole.When spool 2 was in the working position, circular groove 2a was communicated with oil inlet P and outlet A, and two outlet A, B end; When spool 2 was in stop position, oil through 2b was communicated with two outlet A, B, and oil inlet P is ended with outlet A.
Piston 5 step places are provided with Returnning spring 6.
The external drive unit (not shown) of this valve-type oil feeder, can adopt electronic, surge, drive unit such as pneumatic, motor-driven or manual.
The working principle of valve-type oil feeder is as follows: when lubrication system works, drive unit drives spool 2 actions and arrives working position (seeing Fig. 1 or Fig. 3), oil inlet P makes it to be communicated with by the circular groove 2a of spool 2 with outlet A, oil inlet P is then ended with outlet B, the lubricant grease of oil inlet P enters oil suction chamber 4a by the circular groove 2a of spool 2 with outlet A, promote piston 5 and move, pressure spring 6, the lubricant grease that goes out among the oil pocket 4b enters pipeline to the operation point by oil outlet C.
Drive unit stops action or counteragent, spool 2 resets and is in stop position (seeing Fig. 2 or Fig. 4), oil inlet P is cut-off state with outlet A, B, outlet A, B are interconnected by the circular groove 2a (see figure 2) or the oil through 2b (see figure 4) of spool 2, make oil suction chamber 4a and go out oil pocket 4b and connect, spring 6 resets, promote piston 5 and oppositely move, the lubricant grease in the oil suction chamber 4a enters out oil pocket 4b by the circular groove 2a (see figure 2) or the oil through 2b (see figure 4) of outlet A, spool with outlet B.
Piston 5 or oil supply body 1 are provided with separately to oil mass and regulate and the detection device (not shown), so that the lubricant grease amount that goes out oil pocket 4b discharge is adjusted, and carry out oil supply and detect.
This oilier is applicable to the lubricant grease in various different pressures, the viscosity scope.
