Compared with the prior art, the utility model discloses a change traditional sealing washer structure, reach and increase piston head seal degree, increase of service life's effect.
Description
Technical Field
The utility model relates to a sealing washer technical field, more specifically the utility model relates to a novel piston head sealing washer that says so.
Background
The sealing ring is widely applied to various industries as a common mechanical part, is usually applied to dynamic sealing between a piston head and a cylinder body, and mainly plays a role in preventing liquid or gas leakage. Traditional piston head sealing washer realizes sealed effect through sealed muscle, and sealed muscle is in compression state for a long time, and the during operation is less with the lateral wall contact surface, and easy friction is damaged, and life is shorter.
Therefore, with the widespread use of the sealing ring, it is an urgent need to solve the problem of the technical personnel in the field to provide a novel piston head sealing ring with good sealing effect and long service life.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model provides a novel piston head sealing ring, which well solves the above problems, when in operation, the sealing ring extrudes liquid, the groove is filled with body fluid, the sealing rib is outwards expanded, the sealing effect is enhanced, the whole surface is in contact with the side wall of the cylinder body, the friction contact surface is large, and the sealing ring is not easy to be worn and damaged; when the sealing ring returns, the liquid is separated from the groove, the sealing ring is in a free state, the friction force between the sealing rib and the side face is reduced, and the service life is prolonged.
In order to achieve the above object, the utility model provides a following technical scheme: a novel piston head sealing ring is an integrally formed revolving body structure, the top of the novel piston head sealing ring is provided with a U-shaped ring groove, and a cavity is arranged inside the novel piston head sealing ring; the U-shaped ring groove is provided with a circle of sealing ribs on the outer side and an arched bearing body on the inner side.
Preferably, in the above novel piston head sealing ring, the cavity is arranged on the center line of the revolving body structure, and the cavity is a mushroom-shaped mounting groove.
Preferably, in the novel piston head sealing ring, the top of the cavity is an arched bearing body, and the U-shaped ring groove is arranged on the outer side of the cavity.
Preferably, in the novel piston head sealing ring, the bottom of the novel piston head sealing ring is provided with a chamfer.
Preferably, in the novel piston head sealing ring, the novel piston head sealing ring is integrally formed by NBR nitrile rubber.
According to the technical scheme, compared with the prior art, the utility model discloses a novel piston head sealing ring, which utilizes the U-shaped ring groove to adjust the tightness state of the sealing rib, avoids the sealing ring from processing the compression state all the time, and prolongs the service life of the sealing ring; meanwhile, in a working state, the sealing ribs are outwards expanded, and the sealing performance is enhanced.

Fig. 2 is a schematic cross-sectional view of the present invention.
The attached drawing of fig. 3 is the working principle diagram of the utility model.
Fig. 4 is a schematic structural diagram of a conventional sealing ring.
In the figure: 1. a U-shaped ring groove; 2. a cavity; 3. sealing the ribs; 4. an arched receiving body; 5. a liquid.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, for the novel piston head sealing ring disclosed by the present invention, the novel piston head sealing ring is an integrally formed revolving body structure, the top of which is provided with a U-shaped ring groove 1, and the interior of which is provided with a cavity 2; the outside of U type annular 1 is equipped with round sealing rib 3, and the inboard is equipped with arch and holds the body 4.
Preferably, in the novel piston head sealing ring, the cavity 2 is arranged on the central line of the revolving body structure, and the cavity 2 is a mushroom-shaped mounting groove.
Preferably, in the novel piston head sealing ring, the top of the cavity 2 is provided with an arched bearing body 4, and the U-shaped ring groove 1 is arranged outside the cavity 2.
Preferably, in the novel piston head sealing ring, the bottom of the novel piston head sealing ring is provided with a chamfer.
Preferably, in the novel piston head sealing ring, the novel piston head sealing ring is integrally formed by NBR nitrile rubber.
The comparison between the traditional piston head sealing ring and the utility model shows that the structure of the traditional piston head sealing ring is shown in fig. 4, the sealing effect is realized by the sealing rib 3, the sealing rib 3 is in a compressed state for a long time, the contact surface with the side wall is small during working, the friction and the damage are easy, and the service life is short; this use is novel, and at the during operation, sealing washer pushes down liquid 5, and the body fluid is full of U type annular 1, and 3 outer the opening of sealed muscle strengthen sealed effect, whole face and lateral wall contact, and the friction contact face is great, is difficult to wearing and tearing destruction. When the sealing ring returns, the liquid 5 is separated from the U-shaped annular groove 1, the sealing ring is in a free state, the friction force between the sealing rib 3 and the side surface is reduced, and the service life is prolonged.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.
