Abstract
The utility model relates to a quantitative oil feeding distributor which is composed of a valve body, a spacing quantitative member, an outlet oil pipe, a Y-shaped sealing ring, a locating sleeve, an upper spring, a lower spring, a bidirectional cone valve, etc. The quantitative oil feeding distributor uses the bidirectional cone valve made of metal to replace a rubber member for seal, the bidirectional cone valve, the oil inlet sealing surface of a cone valve seat and the sealing surface of a valve rod are all in metal contact seal, and the phenomena of the damage, the deformation and the jam of the rubber sealing member are avoided. The utility model not only satisfies the sealing requirement of the distributor, but also enhances the service life. An oil pipe with phi 6 * 1 does not leak under the oil pressure of 1 to 4 M pa and within 3 meters, the operation is stable and reliable, and most mechanical requirements can be satisfied.
Description
The utility model relates to the machinery centralized oil supply and realizes the device of rationed fuel feeding.
Quantitatively the fuel feeding distributor is used for printing, the rationed lubricant oil of machinery (fat) such as weaving are to the device in supply centre, along with more and more widely the application on all kinds of machinery and various automatic control line of centralized control self oiling mode, make people propose higher reliability requirement to automatic lubricator, and the advance of lubricating fitting and reliability are one of important indicators of weighing machinery complete machine performance, but the existing product distributor all adopts rubber system Sealing as one-way sealing, " floated differential pressure quantitative oil distributor " as the patent No. 95200803.3, by housing, fittings body, valve seat, valve rod, spring, piston, compositions such as control valve, and the rubber system structure of control and employing sealing lip and guide lip disjunctor, because the present situation of China's Tool and Die Technology is also unsatisfactory at present, the quality of rubber product does not far reach people's requirement, seal wear repeatedly appears behind the product export, be out of shape phenomenons such as stuck, reduce working life greatly, can't realize quantitative fuel feeding allocating task for quantitative fuel feeding distributor.
The purpose of this utility model is to avoid the defective of prior art and a kind of quantitative fuel feeding distributor of stable and reliable for performance, long service life is provided.
By the foregoing invention purpose, the utility model is realized by following scheme: comprise a valve body, be provided with the spacing quantitative member that is tightly connected with it in the valve body, the outlet oil pipe is connected the upper end of spacing quantitative member by hollow nut and bipyramid cutting ferrule, the lower end is provided with the valve rod with cross oil through that suit setting sleeve, be provided with upper spring between setting sleeve and the spacing quantitative member, the setting sleeve below is provided with " Y " RunddichtringO, it is characterized in that being provided with the conical valve base of close-fitting at valve body lower end filler opening place, be provided with the two-way cone valve of Spielpassung in the seat, two-way cone valve and be sleeved between the space washer at omoplate place, valve rod lower end and be provided with lower spring.
The utility model replaces the rubber parts sealing of former single track or multiple tracks with two-way cone valve, because of cone valve structure does not simply have the sealing lip structure, so can adopt metal makes, the filler opening sealing surface and the valve stem seal face of it and conical valve base are Metal Contact, sealability is under oil pressure 1-4MPa pressure, 3 meters do not produce seepage with interior with Φ 6 * 1 oil pipes, can satisfy the requirement of overwhelming majority machinery, avoided the breakage of rubber seal, distortion, stuck phenomenon, not only satisfied the seal request of distributor, life-span is improved greatly, make when realizing quantitative fuel feeding allocating task stable and reliable for performance.
Description of drawings.
Fig. 1 is the utility model structural representation (a filler opening closed condition).
Fig. 2 is the utility model structural representation (quantitatively fuel feeding state is opened, finishes once to filler opening).
Below will be elaborated again according to above-mentioned accompanying drawing to embodiment of the present utility model.
The valve body (6) that quantitative fuel feeding distributor (referring to Fig. 1-2) has two ends to communicate, be provided with in the valve body and its spacing quantitative member (4) that seals, is threaded by " O " RunddichtringO (5), outlet oil pipe (1) is connected the upper end of spacing quantitative member by hollow nut (2) and bipyramid cutting ferrule (3), the bipyramid cutting ferrule of ring-type is enclosed within earlier on the outlet oil pipe, is made the distortion of bipyramid cutting ferrule and is tightly sealed up the outlet oil pipe by hollow nut and being threaded of spacing quantitative member.The lower end is provided with suit and valve rod (10) setting sleeve (9) and that have the cross oil through, be provided with upper spring (7) between the omoplate of setting sleeve and spacing quantitative member, when filler opening (16) closed condition, form upper chamber (8), the size of stroke up and down that is related to setting sleeve on the setting sleeve under omoplate and the spacing quantitative member between the omoplate apart from big young pathbreaker, also be the determinant factor that concerns the fuel delivery size, change the fuel delivery size so change the big I of this spacing.The setting sleeve below is provided with " Y " RunddichtringO (11) that 1-3 road closed assembly is arranged, and is sealed into most preferred embodiment with two roads from guiding, has overcome the seepage that the single track sealing causes, forms lower chambers (17) between " Y " seal ring and the space washer.
Valve body lower end filler opening place is provided with the conical valve base (14) of close-fitting, is provided with the two-way cone valve (15) that gap 0.04-0.06 millimeter cooperates in the seat, and two-way cone valve is monolithic construction or split-type structural, and is good with monolithic construction.Two-way cone valve and be sleeved between the space washer (12) at omoplate place, valve rod lower end and be provided with lower spring (13).
Quantitatively fuel feeding distributor and manual or the supporting use of electric oil pump (pressure 1.5-2MPa), when pressure oil P is entered quantitative fuel feeding distributor by filler opening, two-way cone valve overcomes lower spring under the oil pressure effect elastic force moves upward rapidly, and touch the sealed mouth of valve rod oil through, then the oil pressure elastic force that overcomes upper spring promotes " Y " RunddichtringO rapidly and setting sleeve moves upward, and form the lower chambers constantly enter pressure oil, when " Y " RunddichtringO and setting sleeve move upward, when the last omoplate of setting sleeve contacts with the following omoplate of spacing quantitative member, the quantitative oil of upper chamber is through valve rod cross oil through, the outlet oil pipe is delivered to lubricating point, has realized once the quantitatively process (Fig. 2) of fuel feeding.
After hand pump or motor-drive pump release, pressure is reduced to below the 0.03MPa, the pressure oil of lower chambers is pushed two-way cone valve to filler opening rapidly, and under the lower spring effect, tightly seal filler opening, this moment, opened valve rod oil through lower end, pressure oil is entered by the cross oil through setting sleeve and " Y " RunddichtringO is promoted downwards rapidly to disappear until lower chambers, and pressure oil just is stored in upper chamber and finishes oil storage work (figure one), so that quantitative next time fuel feeding.
System is at resting state, upper and lower spring-load minimum.
