Description
Technical field
The utility model is related to a kind of hydraulic fitting, refers in particular to a kind of hydraulic fitting for improving sealing.
Background technology
Hydraulic fitting is as the conventional accessory in hydraulic system pipeline, and transition is connected between being mainly used in hydraulic tube piece,
Existing hydraulic fitting body sealing is poor, generally requires supporting corresponding combined seal ring.
Combination sealing packing ring is the important auxiliary element of hydraulic system, is mainly used in the hydraulic fluid ports such as hydraulic system valve block, oil cylinder
With the end face static seal of hydraulic fitting threaded connection place, major function is to prevent hydraulic system oil liquid from leaking outside.Traditional combination
Seal washer is formed by rubber ring and the vulcanization of becket integrated bond, and it has the disadvantage：Rubber ring non-refractory, high pressure, it is perishable,
Hardness is relatively low, causes hydraulic system oil liquid to leak using i.e. breakage after the short period.
Utility model content
The utility model provides a kind of hydraulic fitting for improving sealing, and its main purpose is to overcome hydraulic fitting
On combination sealing packing ring non-refractory, high pressure, perishable, hardness is relatively low, the defect of cracky.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：
A kind of hydraulic fitting for improving sealing, including body, one end of the body, which is provided with, to be used for and external hydraulic
The hickey of equipment connection, the outer cover of the hickey is provided with a combination sealing packing ring, the combination sealing packing ring bag
Include a cyclic polytetrafluoroethylene packing ring and one be set in metal retaining ring on the cyclic polytetrafluoroethylene packing ring outer ring, it is described
Cyclic polytetrafluoroethylene packing ring end face is abutted against with the body, other end can be abutted against with the external hydraulic equipment.
Further, the metal retaining ring is set in the cyclic polytetrafluoroethylene packing ring in the way of interference fits
On outer ring.
Further, the metal retaining ring is made of stainless steel material.
Compared to the prior art, the beneficial effect that the utility model is produced is:
1st, the utility model is simple in construction, practical, by setting cyclic polytetrafluoroethylene packing ring, can effectively solve
Certainly traditional combination sealing packing ring rubber ring non-refractory, high pressure, it is perishable, the problems such as easy oil leakage, improve hydraulic system pipeline
Sealing effectiveness, it is ensured that hydraulic system is normally run.
2nd, in the utility model, cyclic polytetrafluoroethylene packing ring plays main sealing function, gold by two end face
Category retaining ring is used to prevent cyclic polytetrafluoroethylene packing ring to be deformed making seal failure, and both complement each other, high temperature resistant, resistance to height
Pressure, hardness are high, and good with various hydraulic medium compatibilities, and will not produce corrosion causes breakage, and sealing reliability is high.
3rd, in the utility model, by setting metal retaining ring and the connected mode of cyclic polytetrafluoroethylene packing ring to be
Cross cooperation so that when metal retaining ring or the damage of cyclic polytetrafluoroethylene packing ring or aging, user can only change wherein one
Individual part, is changed together without whole combination sealing packing ring, both facilitates dismounting, and reduce maintenance cost.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is the side sectional view of combination sealing packing ring described in Fig. 1.
Fig. 3 is the top view of combination sealing packing ring described in the utility model.
Embodiment
Illustrate embodiment of the present utility model with reference to the accompanying drawings.
Reference picture 1, Fig. 2 and Fig. 3.A kind of hydraulic fitting for improving sealing, including body 1, one end of the body 1
Provided with the hickey 11 for being connected with external hydraulic equipment 2, the outer cover of the hickey 11 is provided with a combination sealing
Packing ring 3, the combination sealing packing ring 3 is set in the cyclic polytetrafluoroethylene including a cyclic polytetrafluoroethylene packing ring 31 and one
Metal retaining ring 32 on the outer ring of packing ring 31, wherein, the metal retaining ring 32 is made of stainless steel material.The annular poly- four
The end face of PVF packing ring 31 is abutted against with the body 1, other end can be abutted against with the external hydraulic equipment 2.Pass through
Cyclic polytetrafluoroethylene packing ring 31 is set, traditional rubber ring non-refractory of combination sealing packing ring 2, height can be efficiently solved
Pressure, it is perishable, the problems such as easy oil leakage, improve hydraulic system pipeline sealing effectiveness, it is ensured that hydraulic system is normally run.
In application of the present utility model, mainly sealed by two end faces of cyclic polytetrafluoroethylene packing ring, gold
Category retaining ring is used to prevent cyclic polytetrafluoroethylene packing ring to be deformed making seal failure, and both complement each other, and can reach resistance to height
The high effect of warm, high pressure resistant, hardness, and it is good with various hydraulic medium compatibilities, will not produce corrosion causes breakage, sealed reliable
Property it is high.
Reference picture 1, Fig. 2 and Fig. 3.Metal retaining ring 32 is set in the cyclic polytetrafluoroethylene in the way of interference fits
On the outer ring of packing ring 31.Interference fits refer to the cooperation may with gap or interference, now, the tolerance range in hole and the tolerance range of axle
It is mutually overlapping.It is interference fits by setting the connected mode of metal retaining ring 32 and cyclic polytetrafluoroethylene packing ring 31 so that
When metal retaining ring 32 or cyclic polytetrafluoroethylene packing ring 31 are damaged or during aging, user can only change one of part,
Changed together without whole combination sealing packing ring 3, both facilitate dismounting, and reduce maintenance cost.
Embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading the utility model protection domain
