Description
Technical Field
The utility model relates to a mechanical seal technical field especially relates to a two effect hydropneumatic sealing rings.
Background
With the development of modern industry, the complexity of working conditions and the appearance of various hydraulic or pneumatic devices, the importance of mechanical device sealing is self-evident, and the importance of the mechanical device sealing is critical in industrial production, which determines the transmission performance of fluid and gas and the quality of sealing products in industrial automation. The double-acting hydraulic pneumatic sealing ring is a sealing ring matched with the main sealing ring for use and is widely applied to hydraulic and pneumatic transmission systems, so that the double-acting hydraulic pneumatic sealing ring is mainly used for static sealing and reciprocating sealing when in work. But when used for sealing of a piston or piston rod, tend to roll in the groove with the reciprocating motion of the piston or piston rod and tend to fail due to frictional wear.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a can effectual absorption impact load, the two effect hydropneumatic sealing washers of furthest improvement bearing capacity.
The utility model provides a two effect hydropneumatic sealing washers, including the sealing washer body, round square groove has been seted up on the outer diametral plane of sealing washer body, establish to one side of sealing washer body the seal lip of the interior diametral plane slope of sealing washer body, round U-shaped recess has been seted up to the side of sealing washer body opposite side, be equipped with chamfer face one between U-shaped recess and the interior diametral plane, be equipped with chamfer face two between U-shaped recess and the outer diametral plane, sealing washer body opposite side with shoulder one that forms between the square groove highly is greater than sealing washer body one side with shoulder two that forms between the square groove.
Further, the joint of the sealing lip and the shoulder II forms a corner I.
Furthermore, a second corner formed between the axial direction of the sealing ring body and the inner diameter surface of the sealing ring body is 120-180 degrees.
Furthermore, the second corner formed by the sealing lip between the axial direction of the sealing ring body and the inner diameter surface of the sealing ring body is 150 degrees.
Furthermore, the first chamfer surface is arranged to protrude from the inner diameter surface.
Furthermore, the second chamfer surface is arranged by protruding the outer diameter surface.
Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage: the utility model provides a two effect hydraulic pressure pneumatic seal circle when using with the main sealed cooperation of piston rod, can effectual absorption impact load, guarantee reliable and stable sealing performance, the at utmost bears the pressure value and is 16 bar.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1, the utility model provides a pair of two effect hydropneumatic seal rings, including sealing washer body 1, round square groove 3 has been seted up on the external diameter face 2 of sealing washer body 1, establish to the seal lip 5 of 4 slopes of the internal diameter face to the sealing washer body one side of sealing washer body 1, round U-shaped recess 6 has been seted up to the side of sealing washer body 1 opposite side, be equipped with chamfer face one 7 between U-shaped recess 6 and the internal diameter face 4, be equipped with chamfer face two 8 between U-shaped recess 6 and the external diameter face 2, shoulder one 9 that forms between sealing washer body 1 opposite side and the square groove 3 highly is greater than shoulder two 10 that forms between sealing washer body 1 one side and the square groove 3.
The double-acting hydraulic pneumatic sealing ring adopts the unique sealing lip 5 to be matched with the square groove 3 on the outer diameter surface 2 and the U-shaped groove 6 formed in the side surface, stable and reliable sealing performance is provided, various check rings can be matched for ensuring the sealing performance of the sealing element for bearing impact, the elastic modulus is large, good resilience and wear resistance are achieved, when the double-acting hydraulic pneumatic sealing ring is matched with the main seal of the piston rod for use, impact load can be effectively absorbed, and the service life of the main seal is prolonged.
In order to enable the sealing lip 5 which bears pressure during sealing to have a certain buffering effect, a corner I is formed at the joint of the sealing lip 5 and the shoulder II 10, and a corner II formed between the sealing lip 5 and the inner diameter surface 4 of the sealing ring body 1 in the axial direction of the sealing ring body 1 is 120-180 degrees, wherein the corner II is preferably 150 degrees.
In order to enable the other side of the sealing ring body 1 to be better attached and avoid displacement, the first chamfer surface 7 is arranged for the convex inner diameter surface 4, and the second chamfer surface 8 is arranged for the convex outer diameter surface 2.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
