Abstract
Further include sealing ring include outer wall, lower wall, upper wall, inner wall the invention discloses a kind of U-shaped sealing ring of valve in electrically operated valve field, including U-shaped sealing ring ontology；The U-shaped sealing ring is hollow structure；The outer wall lower end extends to form lower wall outward, and the outer wall upper end thinks that inside extends to form upper wall, and the upper wall inner end is downwardly extending inner wall；The outer wall top and middle part are provided with annular protrusion；The inner wall lower end is equipped with turning and extends internally.The configuration of the present invention is simple, U-shaped circle inner wall pressing force are big.
Description
Technical field
The present invention relates to electrically operated valve field, more particularly to a kind of U-shaped sealing ring of valve.
Background technology
The effect of sealing ring is primarily used to prevent the leakage of liquid or gaseous material and foreign object from invading, and has reached sealing
Closed effect.General sealing ring simple designs are rubber ring plate shape, sealing ring be by mould process suppress Lai,
In manufacturing process, sealing ring center bore inner wall easy tos produce burr burr due to die joint, after installation is used, burr hair
Thorn is clipped between axis and sealing ring center bore inner wall, is thoroughly removed since burr burr is more difficult totally, in axis and sealing ring inner wall
Between generate many small gaps, liquid or gaseous matter are leaked or are leaked from gap, while foreign object is relatively easy to invade, and causes
Seal failure.And be not easy detected in anti-leak detection, so that maintenance difficulty is substantially increased.Therefore it is regarding to the issue above
The object that the present invention studies.
Invention content
The object of the present invention is to provide a kind of simple in structure, the big U-shaped sealing rings of valve of pressing force.
The object of the present invention is achieved like this：A kind of U-shaped sealing ring of valve, it is characterised in that：Including U-shaped sealing ring sheet
It includes outer wall, lower wall, upper wall, inner wall that body, which further includes sealing ring,；The U-shaped sealing ring is hollow structure；The outer wall lower end to
Outside extends to form lower wall, and the outer wall upper end thinks that inside extends to form upper wall, and the upper wall inner end is downwardly extending inner wall；
The outer wall top and middle part are provided with annular protrusion；The inner wall lower end is equipped with turning and extends internally.
Compared with prior art, the invention has the beneficial effects that：Since inner wall lower end is provided with turning so that inner wall is held
The pressing force received is bigger.
As the preferred embodiment of the present invention, the inner wall is set as gradient with corner.
As present invention further optimization scheme, the inner wall, upper wall, outer wall form hollow structure.
As present invention further optimization scheme, V-groove is provided on the inside of the annular protrusion positioned in the middle part of outer wall.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Wherein, 1U types sealing ring, 2 outer walls, 3 lower walls, 4 upper walls, 5 inner walls, 6 annular protrusions, 7 turnings, 8V type grooves.
Specific implementation mode
As shown in Figure 1, a kind of U-shaped sealing ring of valve, including 1 ontology of U-shaped sealing ring, further include outer wall 2, lower wall 3, upper wall
4, inner wall 5；U-shaped sealing ring 1 is hollow structure；2 lower end of outer wall extends to form lower wall 3 outward, and inside is thought in 2 upper end of the outer wall
Upper wall 4 is extended to form, 4 inner end of upper wall is downwardly extending inner wall 5；2 top of outer wall and middle part are provided with annular protrusion 6；Inner wall 5
Lower end is equipped with turning 7 and extends internally.
It is set as gradient at 5 inside of above-mentioned inner wall and turning 7.
Above-mentioned inner wall 5, upper wall 4, outer wall 2 form hollow structure.
Above-mentioned 6 inside of annular protrusion positioned at 2 middle part of outer wall is provided with V-groove 8.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing performing creative labour
A little to replace and deform, these are replaced and deformation is within the scope of the invention.
