Abstract
The utility model discloses a kind of novel valve sealing ring, including sealing ring body, three annular protrusions are provided with the position that the sealing ring body is in contact when being sealed with flap, spacing distance between adjacent annular projection is 2mm~3mm, the lateral surface of sealing ring body, which is provided with along sealing ring body thickness direction lineal layout, arc vertical slot, arc vertical slot is evenly distributed on the circumference of sealing ring body, and the sealing ring body is using sealing ring body made of memory plastics.Its is reasonable in design for the utility model, simple in construction, improves to be in contact with flap and is sealed, and substantially increases sealing effectiveness, also causes in the case of pressure rise cannot discharge, and discharges pressure, protects the sealing structure of sealing ring, improve service life.
Description
Technical field
It the utility model is related to valve sealing device technical field, more particularly to a kind of novel valve sealing ring.
Background technology
The known seal that can all use sealing ring general in valve, for existing sealing ring seal due to
It is gap be present between it to be in contact in flap, so as to form the passage of a leakage, is unfavorable for its sealing, while its is existing
Sealing ring is easy to deform when receiving external pressure, causes the damage of sealing ring, is unfavorable for the use in later stage.It is therefore desirable to
Existing sealing ring is made improvements.
The content of utility model
For deficiency of the prior art, the utility model provides a kind of novel valve sealing ring.
To achieve these goals, technical solution adopted in the utility model is：
A kind of novel valve sealing ring, including sealing ring body, what the sealing ring body was in contact when being sealed with flap
Be provided with three annular protrusions on position, the spacing distance between adjacent annular projection is 2mm~3mm, sealing ring body it is outer
Side, which is provided with along sealing ring body thickness direction lineal layout, arc vertical slot, and arc vertical slot is evenly distributed on sealing ring body
Circumference on, the sealing ring body is using sealing ring body made of memory plastics.
The annular protrusion is arc convex, and it is advantageous to improve its sealing.
The sealing ring body medial surface is provided with wearing layer, and the thickness of the wearing layer is 4mm, and wearing layer is to sealing ring
Body plays a protective role, especially the wearing layer of 4mm thickness, extends the service life of sealing ring body, reduces cost, saves
About resource, improve the utilization rate of resource.
The arc vertical slot is 6 so that in the case of pressure rise cannot discharge, discharges pressure, protection sealing
The sealing structure of circle, the arc vertical slot of even number (6) is advantageously in being conveniently evenly distributed on the circumference of sealing ring body.
The beneficial effects of the utility model：Compared with prior art, sealing ring body and flap described in the utility model are close
It is provided with three annular protrusions on the position being in contact during envelope, the spacing distance between adjacent annular projection is 2mm~3mm, its
Be advantageous to the installation being convenient for people to, while be advantageously in contact and sealed with flap in raising, substantially increase sealing effect
Fruit, it is better able to the use demand for meeting people；The lateral surface of sealing ring body is provided with straight along sealing ring body thickness direction
Arc vertical slot is distributed with line, and arc vertical slot is evenly distributed on the circumference of sealing ring body, the sealing ring body using
Sealing ring body made of memory plastics so that in the case of pressure rise cannot discharge, discharge pressure, protect sealing ring
Sealing structure, improve service life；The sealing ring body is using sealing ring body made of memory plastics, favorably
It can also be held its shape in the case of by external force in it.
Brief description of the drawings
Fig. 1 is the utility model moral structural representation；
Fig. 2 is schematic cross-sectional view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of novel valve sealing ring, including sealing ring body 1, the sealing ring body 1 and valve
It is provided with three annular protrusions 11 on the position being in contact during flap seal, the spacing distance between adjacent annular projection 11 is 2mm
~3mm, the annular protrusion 11 are arc convex, and it is advantageous to improve its sealing, and the lateral surface of sealing ring body 1 is provided with
There is arc vertical slot 12 along the thickness direction lineal layout of sealing ring body 1, arc vertical slot 12 is evenly distributed on the circle of sealing ring body 1
Zhou Shang, the arc vertical slot 12 are 6 so that in the case of pressure rise cannot discharge, discharge pressure, protect sealing ring
Sealing structure, the arc vertical slot 12 of even number (6) is advantageously in the circumference for being conveniently evenly distributed on sealing ring body 1
On, it is sealing ring body 1 made of memory plastics that the sealing ring body, which adopts 1, and the medial surface of sealing ring body 1 is set
There is wearing layer 13, the thickness of the wearing layer 13 is 4mm, and wearing layer 13 plays a protective role to sealing ring body 1, especially
The wearing layer 13 of 4mm thickness, extend the service life of sealing ring body 1, reduce cost, saved resource, improve resource
Utilization rate.
The beneficial effects of the utility model：Compared with prior art, sealing ring body and flap described in the utility model are close
It is provided with three annular protrusions on the position being in contact during envelope, the spacing distance between adjacent annular projection is 2mm~3mm, its
Be advantageous to the installation being convenient for people to, while be advantageously in contact and sealed with flap in raising, substantially increase sealing effect
Fruit, it is better able to the use demand for meeting people；The lateral surface of sealing ring body is provided with straight along sealing ring body thickness direction
Arc vertical slot is distributed with line, and arc vertical slot is evenly distributed on the circumference of sealing ring body, the sealing ring body using
Sealing ring body made of memory plastics so that in the case of pressure rise cannot discharge, discharge pressure, protect sealing ring
Sealing structure, improve service life；The sealing ring body is using sealing ring body made of memory plastics, favorably
It can also be held its shape in the case of by external force in it.
