Abstract
The utility model provides a pluse type flow-control valve, which is used for lubricating. Four valve cavities which are communicated with each other in length and width are arranged in a valve body; each valve cavity is provided with a valve core composed of a steel ball and a spring; the upper valve cavity is communicated with an oil inlet, and the right valve cavity and the right valve cavity are communicated with respective oil scales through an oil-dropping tube; a plunger is arranged between the upper valve core and the lower valve core; the respective valve cores of the lower valve cavity, the left valve cavity and the right valve cavity are controlled by three turn knobs outside. The utility model has the advantages of simple structure, easy observation for flow quantity and easy control, which can carry out automatic lubrication under the condition of non-stopping and can make elements doing reciprocating action remain optimal lubrication state without oil-wasting.
Description
The utility model relates to a kind of for the lubricated device of reciprocating action parts, is a kind of pulsed flow control valve.
At present, parts by hydraulic pressure or Mechanical Driven working in reciprocating mode, as lubricating of knife rest, guide rail or slide plate etc., mainly contain following three kinds of modes: one, lubricating cup is pouring-in: per tour work oiling of need repeatedly stopping, even one class notes once, so not only time-consuming, often cause the heavy wear of guide rail or knife rest because of oiling is few.Two, the one-way throttle valve formula is lubricated: its shortcoming is that processing and assembling is difficult, and it is lubricated, time-consuming to need to stop, and the difficult support of flow is held during the manual tune throttle valve.Can't observe the oil mass size, know that behind knife rest lubricant housings effluent oil lubricant oil is sufficient, at this moment close throttle valve and wasted many lubricant oil.Three, bi-bit bi-pass solenoid directional control valve point dynamic formula is lubricated; Its shortcoming is a complex structure, has increased hydraulic pipe line and electric elements.The crawl time is difficult for support holds, and therefore the waste of oil is bigger.As set up the recovering device of lubricant oil on knife rest, that becomes more complicated with its structure and technology.
The purpose of this utility model provides a kind of pulsed flow control valve, and it has not only utilized the pulse lubrication source of the oil pressure variation of to-and-fro motion element as self, and can also effectively control its flow, makes it reach good lubricating status.
The purpose of this utility model is achieved in that and is provided with four valve pockets that communicate in length and breadth in the valve body of this valve, be equipped with the spool that constitutes by steel ball and spring in each valve pocket, wherein two valve core chambers of uuper valve chamber and lower valve chamber are provided with a plunger, and left valve pocket and right valve chamber all communicate with separately oil ga(u)ge by oil dripping tube.Control left and right and lower valve core in the valve body outside by three knobs.
Narrate embodiment of the present utility model according to accompanying drawing below.
Fig. 1 is the structural representation of the utility model pulsed flow control valve.
Fig. 2 is the sectional view along Figure 1A-A line.
As shown in Figure 1, the valve body 1 of this control valve is a cuboid, is provided with four cylindric valve pockets in valve body 1, i.e. uuper valve chamber 2, lower valve chamber 3, left valve pocket 4 and right valve chamber 5, and communicate the intersection in length and breadth by these four valve pockets.Be equipped with the spool that constitutes by steel ball 6 and spring 7 in four valve pockets.Be provided with a plunger 8 between the steel ball 6 of upper valve core and lower valve core, like this, so-called communicating in length and breadth is: left and right sides valve pocket the 4, the 5th, and communicate with lower valve chamber 3 by the oil circuit 9 of spool steel ball 6 front portions separately, and go up lower valve chamber the 2, the 3rd, communicate by the plunger 8 that slides up and down.Rear portion at uuper valve chamber 2 is fixed on its spool in the valve pocket with plug 10, and in the rear portion of lower valve chamber 3, left valve pocket 4 and right valve chamber 5 is fixed on its spool by the pressure regulation rotational structure that is located at valve body 1 outside separately separately valve pocket.The adjusting pressuring knob structure is to be made of screw rod 11, seal ring 12, gland 13, taper pin 14 and knob 15.On the valve body 1 of uuper valve chamber 2 both sides, be arranged with two fastening screws 16, and be arranged with the oil ga(u)ge 17 that dual-purpose transparent material is manufactured on the valve body 1 of lower valve chamber 3 both sides.Oil ga(u)ge 17 by screw threads for fastening in valve body 1, and be provided with sealing gasket 18 in contacting point with valve body, the oil dripping tube 19 of two oil ga(u)ges 17 by separately with respectively with left valve pocket 4 and right valve chamber 5 UNICOMs, splash into lubricant oil in the oil ga(u)ge 17 and then communicate outside the expulsion valve with two oil outlets 20 shown in Figure 2.21 of oil inlet holes that enter in this valve pocket communicate with uuper valve chamber 2.
Narrate the principle of this valve flow control below in conjunction with said structure.Because this valve only is an executive component in whole lubricating system, so enter its inner fluid by other unit feeding.In addition, because it is that to aim at the element of working in reciprocating mode lubricated, the oil pressure of supplying with it like this is (or claiming pulsed) just intermittently.When lubricant oil when oil inlet hole injects uuper valve chamber because the spring in the uuper valve chamber is slightly less than lower valve chamber,, and under the acting in conjunction of oil pressure and upper valve core spring, plunger is depressed during oiling so when intermittence, lower valve core will head into uuper valve chamber to plunger.Like this, during just this slides up and down at plunger the lubricant oil of uuper valve chamber is brought into the intersection of uuper valve chamber and other three valve pockets, and then oil is distributed to left and right valve pocket again.The oil dripping amount of the oil dripping tube in observing left and right sides oil ga(u)ge is not in good time, just can adjust left and right sides knob and control and balance flow separately.If when regulating lower knob, the just oily flow of the whole valve of may command.
The utility model is simple in structure, and flow easily observes, easy to control, and it not only just can drip an amount of lubricating oil in each of parts moves back and forth, and need not stop to lubricate, and does not waste oil, can make lubricated to remain good lubricating status.
Claims (3)
