Description
Technical Field
The utility model belongs to sealing elements, and particularly relates to an expansion tight sealing ring.
Background
The sealing ring is used as a sealing element and is widely applied to various products. The sealing washer is close to compress tightly the laminating with the contact surface of pushing piece that opens and shuts and realizes sealing, and common sealing is external pressure seal, makes the sealing washer pressurized laminating on sealed face through the extrusion of pushing piece that opens and shuts, but such sealing means leads to the mounting stability of sealing washer relatively poor, when pushing piece opens and shuts repeatedly, can lead to the sealing washer to appear becoming flexible and displacement, and then influences sealed effect.
Disclosure of Invention
The utility model aims to provide an expansion tight sealing ring.
To achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides an inflation closely sealing washer, including the sealing washer, the inside of sealing washer is equipped with the pressurization chamber, and the longitudinal section in sealing washer and pressurization chamber is T shape structure, the outside of sealing washer is equipped with a pressurization air cock, the tip and the pressurization chamber intercommunication of pressurization air cock, the upper end of sealing washer be equipped with the coaxial sealing lip who distributes of sealing washer.
Preferably, the upper end of the sealing lip is provided with an annular groove.
Preferably, an inner annular bulge is arranged on the inner side of the bottom of the sealing ring, and an outer annular bulge is arranged on the outer side of the bottom of the sealing ring.
The beneficial effects are that: when the sealing ring is installed, the sealing ring is installed in the annular groove of the sealing part, after the installation, the pressurizing air nozzle is used for pressurizing the pressurizing cavity, so that the pressurizing cavity is in a swelling state, the sealing ring is in a tight contact compression state after being installed in the annular groove by arranging the inner annular bulge and the outer annular bulge, the stability of the sealing ring after the installation is improved, the sealing ring can be further and firmly positioned in the annular groove, when the opening and closing pressing piece is in extrusion contact with the upper end of the sealing ring, the sealing lip is pressed by the sealing lip, and the pressing piece is more attached and stable to the sealing lip due to the fact that the reaction force exists on the sealing lip by the pressurizing cavity after the pressurization, and the annular groove is arranged on the sealing lip, so that the sealing effect is further improved.
The sealing device is simple in structure, the sealing ring is in an expanded state in a pressurizing mode, the sealing effect is improved, the sealing device can be stably and firmly arranged in the annular groove, and the sealing effect is further improved by arranging the sealing lip.
Drawings
In order to more clearly illustrate the technical solution of the embodiments of the present utility model, the following description briefly describes the drawings in the embodiments of the present utility model.
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a cross-sectional view of a seal ring;
wherein: the sealing device comprises a sealing ring 1, a pressurizing cavity 11, an inner annular bulge 12, an outer annular bulge 13, a sealing lip 2, an annular groove 21 and a pressurizing air tap 3.
Detailed Description
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to be limiting of the present patent; for the purpose of better illustrating embodiments of the utility model, certain elements of the drawings may be omitted, enlarged or reduced in size and do not represent the actual product dimensions.
Referring to the figure 1 and the figure 2 show a tight sealing ring expands, including sealing washer 1, the inside of sealing washer 1 is equipped with pressurization chamber 11, and the longitudinal section in sealing washer 1 and pressurization chamber 11 is T shape structure, makes sealing washer 1 and the annular groove of installation position have better cladding nature when the pressurization is expanded, the outside of sealing washer 1 is equipped with a pressurization air cock 3, and the tip and the pressurization chamber 11 intercommunication of pressurization air cock 3, the upper end of sealing washer 1 is equipped with the sealing lip 2 with the coaxial distribution of sealing washer 1.
In this embodiment, the upper end of the sealing lip 2 is provided with an annular groove 21.
In this embodiment, an inner annular protrusion 12 is disposed on the inner side of the bottom of the sealing ring 1, and an outer annular protrusion 13 is disposed on the outer side of the bottom of the sealing ring 1.
When the sealing ring 1 is installed in the annular groove of the sealing part, after the installation, the pressurizing air nozzle 3 pressurizes the pressurizing cavity 11 to ensure that the pressurizing cavity 11 is in an expanded state, the sealing ring 1 is in a tight contact compression state after being installed in the annular groove by arranging the inner annular bulge 12 and the outer annular bulge 13, the stability of the sealing ring after the installation is improved, the sealing ring can be further and firmly positioned in the annular groove, when the opening and closing pressing piece is in pressing contact with the upper end of the sealing ring 1, the sealing lip 2 is pressed and pressed to press the sealing ring due to the fact that the upper end of the sealing ring 1 is provided with the sealing lip 2, and the pressurized pressurizing cavity 11 has a reaction force on the sealing lip due to the fact that the force is mutually applied, so that the contact between the opening and closing pressing piece and the sealing lip is more fit and stable, and the annular groove 21 is arranged on the sealing lip 2, and the sealing effect is further improved.
The sealing device is simple in structure, the sealing ring is in an expanded state in a pressurizing mode, the sealing effect is improved, the sealing device can be stably and firmly arranged in the annular groove, and the sealing effect is further improved by arranging the sealing lip.
The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
