Description
Technical Field
The utility model relates to a well high-pressure seal circle technical field especially relates to a lip is stabilized with one-way area to axle well high-pressure seal circle.
Background
At present, a large number of medium-high pressure sealing rings are used in hydraulic machinery, but the sealing effect of the existing medium-high pressure sealing ring is relatively general under the working condition that hydraulic pressure changes and impacts quickly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the sealing effect is general under the quick operating mode of hydraulic pressure change impact of well high-pressure seal circle among the prior art, and the well high-pressure seal circle of lip is stabilized to an axial one-way belt that provides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a well high-pressure seal circle of lip is stabilized with one-way area to axle, includes the sealing washer main part, sealing washer main part one side fixedly connected with external seal lip and interior seal lip, two the cross-section between external seal lip and the interior seal lip and the sealing washer main part is "Y" shape setting, the position department that the internal diameter of sealing washer main part is close to the bottom is provided with the stabilization lip, sealing washer main part, external seal lip, interior seal lip and stabilization lip set up for integrated into one piece.
Preferably, the sealing ring main body, the outer sealing lip, the inner sealing lip and the stabilizing lip are all made of rubber.
Preferably, the outer diameter of the sealing ring main body is set to be 50.35mm, and the inner diameter of the sealing ring main body is set to be 40.75 mm.
Preferably, the outer diameter of the outer sealing lip is set to 50.97mm, and the cross-sectional thickness of the outer sealing lip is set to 1.37 mm.
Preferably, the inner diameter of the inner sealing lip is set to be 39.07mm, and the cross-sectional thickness of the inner sealing lip is set to be 1.61 mm.
Preferably, the stabilizing lip is triangular in cross-section and has an outer diameter dimension of 40.75mm and an inner diameter dimension of 40.05 mm.
Compared with the prior art, the utility model provides a lip was stabilized to axle with one-way area well high-pressure seal circle possesses following beneficial effect:
this axle is with well high-pressure seal circle of single-way area stabilizing lip, through setting up the sealing washer main part, the external seal lip, interior seal lip and stabilizing the lip, when well high pressure, lean on the hydraulic oil of hydraulic cylinder in to supply pressure to external seal lip and interior seal lip department by the pressure of oil pump, the oil pressure can be to the extrusion of external seal lip and interior seal lip department seal lip both sides, external seal lip and interior seal lip atress also extrude to hydro-cylinder and axle department, thereby play the sealing effect, pressure is higher the better leakproofness. However, when the hydraulic pressure changes rapidly, an unstable angle appears at the lip position of the pull rod, and leakage easily occurs at inclination. The stable lip is added at the root of the inner hole, so that the inclination phenomenon of the main body of the sealing ring can be eliminated.
The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model discloses change at the sealing washer and strike under the operating mode very fast, its sealed effect also can keep better level.
Drawings
Fig. 1 is a schematic cross-sectional view of a middle-high pressure seal ring with a stabilizing lip for an axial one-way belt according to the present invention.
In the figure: 1 a sealing ring main body, 2 an outer sealing lip, 3 an inner sealing lip and 4 a stabilizing lip.
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.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1, a middle and high pressure seal ring with a stable lip for a shaft, which comprises a seal ring main body 1, one side of the seal ring main body 1 is fixedly connected with an outer seal lip 2 and an inner seal lip 3, the cross sections between the two outer seal lips 2 and the inner seal lip 3 and the seal ring main body 1 are arranged in a Y shape, the position of the inner diameter of the seal ring main body 1 close to the bottom is provided with the stable lip 4, the seal ring main body 1, the outer seal lip 2, the inner seal lip 3 and the stable lip 4 are integrally formed, when the middle and high pressure is reached, pressure is supplied to the outer seal lip 2 and the inner seal lip 3 by the pressure of a hydraulic oil pump in a hydraulic oil cylinder, the oil pressure can be extruded to the two sides of the seal lips at the outer seal lip 2 and the inner seal lip 3, the outer seal lip 2 and the inner seal lip 3 are also extruded to the oil cylinder and the shaft under the stress, so as to play a sealing role, and the higher pressure is better in sealing performance.
