Description
Technical field
The utility model is related to industrial field of sealing technology, more particularly to a kind of piston rod sealing ring.
Background technology
In machinery industry, especially during piston rod use, the sealing property of sealing ring can directly influence production
The factors such as the production efficiency of equipment, useful life and security, because the sealing ring of piston rod in the prior art is more or less
Bearing capacity when there are problems that insufficient strength, gap are larger, pressure is larger, when pressure of the piston rod in cylinder body is larger
When, it is susceptible to leakage accident.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of simple structure, good seal performance also having
There is the piston rod sealing ring of certain cushioning effect.
The piston rod sealing ring that the utility model is provided, including sealing ring, two O-rings and two sealing lips,
The inside diameter surface of the sealing ring is provided with V-shaped groove, and the external diameter surface of the sealing ring is provided with groove, the sealing ring it is interior
Two sealing lips towards internal diameter of the seal ring face varus, two sealings are provided between footpath surface and external diameter surface
Lip is symmetricly set on closely embedding in the gap formed between the both sides of the sealing ring and each described sealing lip and sealing ring
Entering has the O-ring.
Further, also including two dust seal lips turned up towards the sealing ring outer diameter face, two described dust-proof
Sealing lip is symmetricly set on the both sides of the sealing ring and the dust seal lip is located at the external diameter of the sealing lip and sealing ring
Between surface.
Further, the angle between the dust seal lip and sealing ring is 90~120 °.
Further, length of the length of the dust seal lip more than or equal to the sealing lip.
Further, the angle in the gap for being formed between the sealing lip and sealing ring is 30~60 °.
Further, the O-ring is Viton circle.
Further, the angle of inclination of two side walls is 120 ° in the groove.
Further, the groove is arc groove, and the both sides in the internal diameter of the seal ring face are chamfering.
By such scheme, the utility model at least has advantages below：In order to solve piston rod during machinery production
The problems such as easily leakage and durability are inadequate, the piston rod that the utility model is provided is with ring structure is simple, sealing property
Well also there is certain cushioning effect.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is the structural representation of the piston rod sealing ring that the utility model is provided.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
Referring to Fig. 1, a kind of piston rod sealing ring of the preferred embodiment of the utility model one, including a sealing ring 1, two
Individual O-ring 2 and two sealing lips 3, the inside diameter surface of sealing ring 1 are provided with V-shaped groove 4, and the external diameter surface of sealing ring 1 is provided with recessed
Groove 5, is provided with two sealing lips 3 towards the aperture surface varus of sealing ring 1, two between the inside diameter surface and external diameter surface of sealing ring 1
Individual sealing lip 3 is symmetricly set in the gap formed between the both sides of sealing ring 1 and each sealing lip 3 and sealing ring 1 closely
It is embedded with O-ring 2.
The operation principle of the piston rod sealing ring that the utility model is provided is as follows：
This piston rod can be risen with the groove 5 on the V-shaped groove 4 and outer diameter face on the aperture surface of the sealing ring 1 in sealing ring
To the effect of dispersing hydraulic pressure and liquid storage, the sealing of sealing ring 1 and durable performance are further consolidated, further, since to close
The sealing lip 3 of the aperture surface varus of seal 1 is symmetricly set on the both sides of sealing ring 1, and the seam between sealing lip 3 and sealing ring 1
Gap is embedded with the same O-ring 2 with sealing and cushioning effect, thus the O-ring 2 of sealing lip 3 with the use of making sealing ring 1
Also there is cushion effect well while with sealing property well.
In order to preferably realize the anti-dust performance of piston rod packing circle, also turned up towards the outer diameter face of sealing ring 1 including two
Dust seal lip 6, two dust seal lips 6 are symmetricly set on the both sides of sealing ring 1 and dust seal lip 6 is located at sealing lip 3
And the external diameter surface of sealing ring 1 between, the length of the length more than or equal to sealing lip 3 of dust seal lip 6；So, it is located at
Dust seal lip 6 between sealing lip 3 and the outer diameter face of sealing ring 1 can play most using for certain sealing and dustproof to sealing ring 1.
In order to piston rod packing circle is better achieved to the resiliency that is stressed, between dust seal lip 6 and sealing ring 1
Angle is 90~120 °.
In order to by O-ring 2 be preferably embedded between sealing lip 3 and sealing ring 1 formed gap in, sealing lip 3 and sealing
The angle in the gap formed between circle 1 is 30~60 °.
In order to realize the sealing of piston rod packing circle and the performance of compensator or trimmer pressure, O-ring 2 is Viton circle.
In order to prevent sealing ring 1 to be extruded in seal process, the angle of inclination of two side walls is 120 ° in groove 5.
In order that obtaining sealing ring 1 has better seal performance, groove 5 is arc groove, the both sides of the aperture surface of sealing ring 1
It is chamfering.
The above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for
For those skilled in the art, on the premise of the utility model know-why is not departed from, if can also make
Dry to improve and modification, these are improved and modification also should be regarded as protection domain of the present utility model.
