Description
Technical field
The present invention relates to sealing ring technical field, specifically a kind of combined type packing ring.
Background technology
Revolving hydraulic rotation all be present in each industrial circle such as engineering machinery, building machinery and automobile equipment.It is used
In bar, axle, swivel joint for being sealed with rotation or oscillating motion etc., it is that one kind can bear pressure at both sides or alternating pressure is made
The rotating seal ring of two-way function.At present, during the use of sealing ring, because the use environment of sealing ring is severe,
So the service life of sealing ring is extremely short.Therefore in the market needs a kind of complex, the sealing ring of service life length.
The content of the invention
According to above the deficiencies in the prior art, the technical problems to be solved by the invention are to propose a kind of combined labyrinth and carbon gland
Circle.
The present invention is solved its technical problem and realized using following technical scheme：
A kind of combined type packing ring, including sealing ring body, it is recessed that No.1 is provided with the madial wall of the sealing ring body
Groove, No.1 O-ring is provided with No.1 groove, No. two grooves are provided with the lateral wall of sealing ring body, are set in No. two grooves
No. two O-rings are equipped with, the lower end of sealing ring body, which is provided with, deposits fat groove, and No.1 groove, No. two grooves are connected with depositing fat groove.
No.1 groove described in said apparatus is located at the bottom of sealing ring body.
No. two grooves are located at the top of sealing ring body described in said apparatus.
The top of sealing ring body described in said apparatus is provided with the flange extended to madial wall.
The upper end of flange described in said apparatus is provided with inclined plane.
No.1 O-ring described in said apparatus uses the quality of rubber materials of hydrogenated butyronitrile.
No. two O-rings use the quality of rubber materials of butyronitrile described in said apparatus.
The beneficial effects of the invention are as follows：
The present invention has the advantages of structure design is simple, service life is long, passes through sealing ring body, No.1 O-ring and two
The cooperation of number O-ring, realizes to the multi-layer sealed of piston rod, ensure that the airtight quality of piston rod, while also in sealing ring
It is provided with body and deposits fat groove, facilitate the lubrication to No.1 O-ring and No. two O-rings, adds the service life of sealing ring.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below by the description to embodiment, the shape of for example involved each component of embodiment of the invention, structure
Make, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and the side of operating with
Method etc., is described in further detail, completeer to help those skilled in the art to have inventive concept of the invention, technical scheme
Whole, accurate and deep understanding.
As shown in figure 1, a kind of combined type packing ring, including sealing ring body 1, on the madial wall of the sealing ring body 1
No.1 groove 1a is provided with, No.1 O-ring 2 is provided with No.1 groove 1a, No. two are provided with the lateral wall of sealing ring body 1
No. two O-rings 3 are provided with groove 1b, No. two groove 1b, the lower end of sealing ring body 1, which is provided with, deposits fat groove 1c, No.1 groove
1a, No. two groove 1b are connected with depositing fat groove 1c.In use, the lower end that fat groove 1c is arranged on sealing ring body 1 is deposited, can not
Influence the structural strength of sealing ring.
No.1 groove 1a is located at the bottom of sealing ring body 1.
No. two groove 1b are located at the top of sealing ring body 1.
The top of sealing ring body 1 is provided with the flange extended to madial wall.
The upper end of flange is provided with inclined plane.
No.1 O-ring 2 uses the quality of rubber materials of hydrogenated butyronitrile.
No. two O-rings 3 use the quality of rubber materials of butyronitrile.
In use, sealing ring body 1 is installed in hydraulic cylinder, inwall and the piston rod of sealing ring body 1 fit,
In the moving process of piston rod, flange can stop to the dirt on piston rod outer wall, and utilize the inclination on flange
Face carries out water conservancy diversion, reduces the impact that sealing ring body 1 receives；When sealing ring body 1 is under pressure, pressure makes sealing ring body 1
Deformation is produced, during deformation, the lubricant grease in fat groove 1c is deposited and is extruded into No.1 groove 1a and No. two groove 1b,
No.1 O-ring 2 and No. two O-rings 3 are lubricated, prevents No.1 O-ring 2 and No. two O-rings 3 from lubricating inequality, causes one side
Abrasion, improve service life；No.1 O-ring 2 is fitted on the outer wall of piston rod, can further sealing piston bar, prevent
Metal iron filings are entered into hydraulic cylinder；No. two O-rings 3 are arranged in cylinder barrel, can be with the installation on further protection cylinder barrel
Groove；After No.1 O-ring 2 wears, capable protection can also be tapped into sealing ring using sealing ring body 1.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as employing the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress, or not improved this is sent out
Bright design and technical scheme directly applies to other occasions, within protection scope of the present invention.The protection of the present invention
Scope should be determined by the scope of protection defined in the claims.
