Description
Technical field
The present invention relates to lubricating arrangement technical field, and in particular to a kind of pressure release type available for grease distribution is rationed
Device.
Background technology
Quantitative oil distributor is connected on machine to be lubricated, the position that each needs that lubricating oil is delivered into machine lubricate,
So as to ensure the smoothly operation of machine.Authorization Notice No. is practical for CN2324374Y (Patent No. 98211197.5) China
New patent《Oil header》, wherein disclosed oil header structure can provide thin oil measured lubrication oil, have
Check valve is provided with preferable not oil return and leakage resistance, the oil header, the check valve is usually using rubber etc.
Elastomeric material is made, to realize good sealing function.But in high pressure use environment, in such as grease quantitative lubricating system,
The check valve and valve stem seal end are fragile and there is the problem of service life is short, and then influence the entirety of oil header to make
Use the life-span.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of energy high pressure resistant and service life for above-mentioned prior art
Long can be used for the pressure-releasing type quantitative distributor that grease is distributed.

Fig. 2 is a kind of structure chart of check valve in the embodiment of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, a kind of pressure-releasing type quantitative distributor distributed available for grease in the present embodiment, including housing 1,
Valve rod 2, valve pocket 3, valve seat 4, spring 5 and check valve 6.
Radially-inwardly tighten up setting to form large aperture section and small-bore section, housing 1 in the lumen in one end of the inner chamber of housing 1
Inwall on large aperture section and small-bore section boundary formation one step surface.Housing 1 is opened in the end of small-bore section one end
Provided with fuel feed hole 11, offered in the end of large aperture section one end and be connected with a joint in oil outlet, oil outlet to facilitate connection
Flowline.
Valve rod 2 axially penetrates through the perforate 22 for offering and being further opened with being connected on straight oilhole 21, valve rod 2 with straight oilhole 21.
Valve seat 4 is spacing to be set in outside valve rod 2, in the present embodiment, and one end of valve rod 2 has one week groove, and valve seat 4 is then spacing
It is set in the groove.The periphery of the end of valve seat 4 is against on step surface to be fixed on valve rod 2 in the large aperture section of housing 1, is entered
And cause the straight oilhole 21 of valve rod 2 is corresponding with oil outlet to be connected.The aperture with the inner chamber of housing 1 is offered on valve seat 4 vertically
The aperture 41 that footpath section is connected.
Valve pocket 3 is set in outside valve rod 2, same as the prior art, valve pocket 3 close to one week of the end of fuel feed hole 11 radially to
Flange is convexly equipped with outside, the outer wall of flange is adjacent on the inwall of housing 1.
Spring 5 is then set in outside valve pocket 3, and the spring 5 is located in the space between valve pocket 3 and the inwall of housing 1, and the two of spring 5
End is against on the inner face of the flange of valve pocket 3 and joint respectively.
Check valve 6, is arranged in the section of the small-bore of housing 1.The check valve 6 includes flexible sealing 61 and is embedded
The matrix 62 of hard in sealing 61, allows lubricating oil to lead to check valve 6 under the pressure effect in 11 oil-feed of fuel feed hole
Cross and enter in housing 1, and the sealing fuel feed hole 11 in the case of the release of pressure of fuel feed hole 11.As needed, matrix 62 can be with
From metalworks such as screw rod, screw or rivets, the center of sealing 61 has the blind hole matched with matrix 62, and matrix 62 is then embedding
It is located in the blind hole.And matrix 62 is arranged in blind hole from oil outlet to the direction of fuel feed hole 11.When lubrication oil medium is used
During grease, then the input pressure of fuel feed hole 11 is larger.The stress of check valve 6 increases, and the power for pressing valve rod 2 also increases therewith, unidirectionally
The hard substrate 62 being embedded in valve 6 increases the end face seal effect between check valve 6 and valve rod 2, while improving check valve 6
Bearing capacity, so as to ensure that check valve 6 is reliably used for a long time, is hardly damaged, service life is long.In addition, the peace of matrix 62
Dress direction ensure that the integrality of 61 bottoms of sealing, it is ensured that lubricating oil have enough pressure self-sealing portion 61 and the inwall of housing 1 it
Between gap enter in housing 1, it is achieved thereby that the normal operation of the distributor.
Sealing 61 is folded provided with being in for two layers runcinate sealing lip 611, and the cross section of the sealing lip 611 is V-shaped or square
Shape.Such as sealing 61 can be made up of two layers of V-shaped sealing lip 611, or as shown in Fig. 2 sealing 61 is by one layer of V-shaped
Folded set of sealing lip 611 and one one-tenth rectangular sealing lip 611 forms, and rectangular sealing lip 611 is close to fuel feed hole 11.Sealing lip
611 while one-way sealing is ensured, increases the self- steering function of check valve.
The use process of the pressure-releasing type quantitative distributor is：In lubricating oil from after entering in housing 1 fuel feed hole 11, lubricating oil
Pressure promote check valve 6 moved to valve rod 2, when the end face of check valve 6 is against on valve rod 2, then block the straight oilhole of valve rod 2
21, with being constantly pumped into for lubricating oil, the pressure acted on check valve 6 gradually increases, and then oppresses the sealing on check valve 6
Lip 611 deforms, and the space between lubricating oil self sealss lip 611 and the inwall of housing 1 flows to valve seat 4, then through the aperture on valve seat 4
41 are flowed into and act in the flange end face of valve pocket 3, and valve pocket 3 is moved under the pressure effect of lubricating oil to oil outlet direction therewith
It is dynamic, meanwhile, spring 5 gradually reduces.The oil pressure of lubricating oil so between valve pocket 3 and the inwall of housing 1 in gap rises, Jin Ertong
Cross the perforate 22 on valve rod 2 to enter in the straight oilhole 21 of valve rod 2, last lubricating oil is delivered to oil outlet through straight oilhole 21, enters
And realize the lubrication to lubricating machinery.When the ends contact of valve pocket 3 is to joint, complete once to quantify oil extraction process.
Stop after lubricating oil supply, the release of pressure at fuel feed hole 11, valve pocket 3 is then under the elastic force effect of spring 5 to entering
The direction of oilhole 11 is moved, and the lubricating oil between the flange of valve pocket 3 and valve seat 4 presses to check valve 6 from the aperture 41 on valve seat 4, unidirectionally
The sealing lip 611 of valve 6 is contacted with the inner wall sealing of housing 1, while lubricating oil promotes movement of the check valve 6 to fuel feed hole 11, this
When, check valve 6 then opens the closure to straight oilhole 21 in valve rod 2, and lubricating oil enters straight oilhole 21, and by opening on valve rod 2
Hole 22 is flowed in the space between valve pocket 3 and the inwall of housing 1, in case oil extraction process is used.
