Abstract
The utility model discloses a O type circle for brake pump, including O type circle body, this internal annular metal core that is equipped with of O type circle, O type circle body has inner seal face and outer sealing surface, inner seal face's integrative the taking shape of downside has interior secondary seal lip, outer sealing surface's integrative the taking shape of upside has outer secondary seal lip, interior secondary seal lip with the line of centres of outer secondary seal lip with the infusion set of O type circle body is 20 degrees contained angles, O type circle body reaches interior secondary seal lip, the outer secondary seal lip polytetrafluoroethylene coating that has all coated. The utility model discloses a O type circle has multiple sealed face, wear -resisting high temperature resistant, difficult upset distortion, long service life's characteristics.
Description
Technical field
This utility model is related to a kind of O-ring and in particular to a kind of O-ring for brake pump.
Background technology
There is a problem of that service life is short currently used for the O-ring on brake pump, concrete manifestation is such as：O-ring sealing surface grinds
Loss effect, high temperature ageing lost efficacy, upset distorts Cracking Failure etc., Shortcomings.
Utility model content
For above-mentioned deficiency, this utility model provides a kind of O-ring for brake pump, has multi-sealed face, wear-resisting
High temperature resistant, be difficult upset distortion, the feature of long service life.
The technical solution of the utility model is：
A kind of O-ring for brake pump, including O-ring body, described O-ring is originally provided with the metal of an annular in vivo
Core；Described O-ring body has inner sealing surface and external seal face；The downside of described inner sealing surface is formed with interior secondary sealing
Lip, the upside in described external seal face is formed with outer secondary sealing lip；In described interior secondary sealing lip and described outer secondary sealing lip
Heart line is in 20 degree of angles with the horizontal center line of described O-ring body；Described O-ring body and described interior secondary sealing lip, outer
Secondary sealing lip is coated with polytetrafluorethylecoatings coatings.
Further, the section of described metal inside is in crosswise, and the level in its section is more than vertically to length to length.
The utility model has the advantages that：In O-ring of the present utility model, all there are double sealing surface, good sealing effect in outside；
Setting metal inside still prevents O-ring upset distortion while improving bulk strength；Being coated with polytetrafluorethylecoatings coatings can
To improve high temperature resistant, the wear-resistant and self-lubricity energy of O-ring.
Brief description
Fig. 1 is cross section structure schematic diagram of the present utility model.
Specific embodiment
Embodiment：
As shown in figure 1, a kind of O-ring for brake pump, including O-ring body (1), set in described O-ring body (1)
There is the metal inside (2) of an annular；Described O-ring body (1) has inner sealing surface (3) and external seal face (4)；Described interior sealing
The downside in face (3) is formed with interior secondary sealing lip (5), and the upside of described external seal face (4) is formed with outer secondary sealing lip
(6)；In the level of the line of centres of described interior secondary sealing lip (5) and described outer secondary sealing lip (6) and described O-ring body (1)
Heart line is in 20 degree of angles；Described O-ring body (1) and described interior secondary sealing lip (5), outer secondary sealing lip (6) are coated with poly- four
Fluorothene coating (7).
Further, the section of described metal inside (2) is in crosswise, and the level in its section is more than vertically to length to length
Degree.
The above is preferred implementation of the present utility model it is noted that ordinary skill for the art
For personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and moisten
Decorations are also considered as protection domain of the present utility model.
