The utility model discloses the effectual leakage problem of seal structure at the in-process of operation of having solved, under adverse conditions, the homoenergetic reaches fine sealed effect.
Description
Technical Field
The utility model belongs to the technical field of sealed technique and specifically relates to a novel combined seal structure is related to.
Background
In the hydraulic transmission field, the hydraulic oil cylinder performs reciprocating motion under the pushing of hydraulic oil, most of the sealing of the oil cylinder under the condition adopts a check ring and an O-shaped ring or a Y-shaped ring, but the common sealing structure is difficult to meet different working conditions along with the change of working conditions, and the normal production work is influenced.
Therefore, a sealing structure having a simple structure and a good sealing effect is required.
Disclosure of Invention
An object of the utility model is to solve above-mentioned technical problem, lie in providing a simple structure, have the seal structure of good effect. The problem of oil leakage in the sealing process is solved. The sealing device can achieve good sealing effect under different pressure environments, and the sealing effect is better.
The utility model discloses a high temperature and high pressure resistant Y shape circle composite seal structure, the technical problem of solution is realized by following technical scheme.
The utility model provides a high temperature and high pressure resistant Y shape circle combination seal structure, includes a Y shape sealing washer, a triangle-shaped cross-section metal seal circle, two size difference, opposite direction, the metal seal circle of right trapezoid cross-section is constituteed. The method is characterized in that: the described sealing structure includes Y-shaped ring seal and three working parts of metal sealing rings with different shapes and sizes.
As a preferable technical scheme, a V-shaped groove is arranged between the outer lip and the inner lip of the Y-shaped sealing ring, oil with pressure enters the groove, and the outer lip and the inner lip can generate pressure, so that the sealing effect is improved. The method is characterized in that: the cross section of the Y-shaped ring is provided with a triangular groove.
As a preferable technical scheme, a chamfer is arranged on the outer edge of the bottom end of the Y-shaped sealing ring.
As a preferred technical scheme, the Y-shaped sealing ring is made of polyurethane, the sealing ring made of polyurethane can reduce the compression deformation of oil on the Y-shaped sealing ring, the wear-resisting effect is good, and the service life of the structure is prolonged.
As a preferable technical scheme, the triangular metal sealing ring is clamped in a groove which is formed by a chamfer angle of the Y-shaped sealing ring and a sealing outer wall and has a certain angle, and the pressure applied to the Y-shaped sealing ring can be uniformly transmitted to the metal sealing ring with the lower triangular section. The method is characterized in that: the metal sealing ring with the triangular section is clamped in the triangular groove of the Y-shaped ring.
As a preferable technical scheme, two inclined planes of the two metal sealing rings with right trapezoid cross sections are attached, and in the process of axial movement, self-reinforced sealing is performed through the wedge shape of the inclined planes, so that the sealing strength is increased.
As an optimal technical scheme, the other right-angle surface of the metal sealing ring with the triangular interface is attached to the metal sealing ring with the trapezoidal section, and the pressure applied to the triangular sealing ring is transmitted to the sealing ring with the trapezoidal section, so that the problems of sealing unbalance loading and oil leakage can be solved.
Compared with the prior art, the utility model discloses an it lies in when the oil pressure that the structure bore is too big a bit, and this seal structure can utilize the radial force and the adhesive action that the outer lip and the inner lip of Y shape sealing washer produced and the radial force that triangle-shaped sealing washer and trapezoidal sealing washer produced under the circumstances of static seal, solves the leakage problem of fluid and because of the unbalance loading distortion problem that the pressure is unstable produces. And the utility model discloses the effectual sealing lip of having solved the sealing washer in the use problem that is not wear-resisting can reach fine sealed effect to can increase of service life.
