Abstract
The utility model discloses a F-shaped slide ring combination seal, which comprises an F-type slide ring and an O-shaped rubber ring embedded into the F-shaped slide ring concave groove. The utility model has advantages of simple structure, easy installation, high-pressure resistance, good sealing performance and long working life etc., which is suitable for fluid high-pressure rotation sealing and reciprocating movement sealing.
Description
Technical field
The utility model relates to a kind of combination sealing arrangement, is particularly useful for fluid high-pressure rotary seal and reciprocating movement sealing.
Background technique
Sealing member for rotating shaft is generally outside framework oil seal on the machinery, and the skeleton oil seal performance is good, anti-high speed, but its voltage endurance capability is not high, and working pressure is generally less than 0.05MPa, the highest 3MPa that is no more than.
Summary of the invention
The purpose of this utility model provides that a kind of high pressure resistant, good seal performance, surface friction drag are little, the F shape sliding ring type combination seal of long working life.
The utility model is realized with following technological scheme: sealing is made up of a F shape slip ring and an O shape rubber ring that embeds in the F shape slip ring groove.Lip is shaped on a steeper chamfering, and heel leaves one 45 ° chamfering.
Its good effect is: owing to adopted such scheme, can make model utility have advantages such as high pressure simple in structure, easy for installation, anti-, good seal performance, long working life.Be particularly useful for fluid high-pressure rotary seal and reciprocating movement sealing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a cut-away view of the present utility model;
Fig. 2 is an installation cut-away view of the present utility model.
Among the figure: 1.F shape slip ring, 2.O shape rubber ring, 3. seal chamber, 4. gland, 5. piston rod, arrow is depicted as the pressure direction of fluid.
Embodiment
By Fig. 1 and Fig. 2 as can be known, the utility model comprises a F shape slip ring (1) and an O shape rubber ring (2) that embeds in the F shape slip ring groove.There is a flange F shape slip ring outside, can prevent that slip ring from rotating with axle in groove.Lip is shaped on one, and sealing lip is short and thick, has reduced frictional force greater than 60 ° chamfering α, thereby uses long working life.Lip thickness δ decides according to different operating modes.The heel of lip has undercut ss, and best angle is 45 °.Flange rib width dimensions is that b is 1-3mm, and F shape slip ring material is to be made by the polytetrafluoroethylplastic plastic of modification.
Its working principle is: O shape rubber ring embeds in the groove of F shape slip ring, and O shape rubber ring plays the elastic force-applying effect.The elastic force of O shape circle guarantees the sealing of F shape slip ring under zero-pressure or low pressure, and when system pressure raise, main sealing force was made up of system pressure, and system pressure tightly is attached on sealed the lip of slip ring, and pressure is high more, and sealing is good more.
Claims (3)
1, a kind of F sliding ring type combination seal is characterized in that sealing is made up of the O shape rubber ring that a F shape slip ring and embed in the F shape slip ring groove.
2, F shape slip ring combination seal according to claim 1 is characterized in that F shape slip ring material is to be made by the polytetrafluoroethylplastic plastic of modification.
3, F shape slip ring combination seal according to claim 1 is characterized in that the flange rib width b of F shape slip ring is 1-3mm, and the lip chamfering is greater than 60 °, and the heel chamfering is 45 °.
