Abstract
The utility model belongs to a sealing part for a hydraulic system, which is especially suitable for a hydraulic braking system of an automobile. The sealing part forms an annular shape. The utility model is characterized in that two cutting edges (1, 3) and a circular face are arranged on the surface of an outer ring of the sealing part, and the two cutting edges (1, 3) are respectively and outwards positioned on both ends of the sealing part. The utility model has the advantage that due to adoption the structure, the sealing part can perform a sealing action under the three conditions of high-pressure seal, non-pressure seal and vacuum seal so as to simplify the structure of a hydraulic systems, enhance the level of process production and ensure the reliable operation of the hydraulic system.
Description
The utility model belongs to the Sealing that a kind of hydraulic system is used.Be specially adapted to hydraulic braking system for automobile.
Lip ring in the past, its outer shroud are generally smooth disc or have only a cutting edge, and it is placed in the hydraulic system, can solve high pressure sealing or not have means of press seals or vacuum-packed wherein a kind of.Because the structural limitations of this Sealing, its seal action is single, thereby causes the structure of hydraulic system loaded down with trivial details etc.
The purpose of this utility model is, with Sealing outer shroud surface design for two cutting edges and a disc are arranged, thereby realized solving high pressure sealing, no means of press seals and vacuum-packed problem simultaneously with the single-piece Sealing.
The utility model is achieved in that a kind of Sealing, is annular, it is characterized in that: two cutting edges (1,3) and a disc (2) are arranged on the outer ring surface of Sealing, and described two cutting edges (1,3) lay respectively at the Sealing two ends, and cutting edge outwardly.
Described two cutting edges (1,3), one of them is thick thick, another is a taper.
Do further explain below in conjunction with accompanying drawing.
Fig. 1 (a, b): the plan view of Sealing and side view.
Fig. 2: the working state figure of Sealing.
See Fig. 1 and 2, this Sealing is put into cylinder 4, with the casing wall interference fit, 6 is liquid, and 5 cutting edges 3 that generally are positioned at the inner chamber place for piston are comparatively thick thicker, and comparatively taper is a little to be positioned at cutting edge 1 outside the chamber, sees shown in Figure 2.When vacuumizing (can reach negative 760mmHG vacuum), cutting edge 1 is adjacent to casing wall, makes that hydraulic system is inner to guarantee that no vacuum leaks between piston and casing wall; When exhausting vacuum, during the hydraulic system full of liquid, giving between disc 2 between two cutting edges and casing wall is pressed with to imitate when having stoped system liquid not have pressure and leaks; When hydraulic work system, hydraulic pressure has had pressure, and then cutting edge 3 is pressed on the casing wall, does not leak when guaranteeing the hydraulic system high pressure.
The utility model has the advantages that: owing to adopt said structure, make seal in high pressure sealing, with no pressure Can both play sealing function in sealing and three kinds of situations of vacuum seal, this just simplifies the hydraulic system knot widely Structure improves the explained hereafter level, and the assurance hydraulic system is worked reliably.
Claims (2)
1, a kind of Sealing is annular, it is characterized in that: two cutting edges (1,3) and a disc (2) are arranged on the outer ring surface of Sealing, and described two cutting edges (1,3) lay respectively at the Sealing two ends, and cutting edge outwardly.
2, by the described Sealing of claim 1, it is characterized in that: described two cutting edges (1,3), one of them be slightly thick, another is a taper.
