Description
Technical field
The utility model is related to the technical field of seal ring structure, particularly a kind of novel valve sealing ring.
Background technology
Seal ring seal is exactly to open a groove on two surfaces that works in coordination（According to sealing ring-shaped fluting）,
Sealing ring is inserted the inside, plays a part of sealing.Seal ring seal purposes is widely.It is seen everywhere in daily life.Press
Sealing ring-shaped is divided and has many kinds, most basic and common are O-shaped sealing ring, U-shaped sealing ring and Y type sealing ring.Sealing ring
Material has the plastics and rubber of metal, carrys out the type from sealing ring by use environment and working pressure class.Typically
The U-shaped sealing ring of the employing of the O-shaped sealing ring high pressure of the employing of low pressure.
The valve body of wherein vertical setting（Such as stop valve, regulating valve etc.）Sealing ring access times at most, its purpose is to
The slot leakage of the medium of flowing from upper valve base and lower valve base touching position is prevented, and the sealing ring on sealing ring is subject to upper valve base
Extruding force effect, while by the horizontal shear force from liquid medium, ultimately resulting in sealing ring crimp, being absorbed in annular
In groove, only destroy sealing ring and sealing ring manipulation could be changed, but after destroying, the defective material of sealing ring is stayed in cannelure, shadow
The sealing of next one sealing ring is rung, therefore there is the defect that integrally sealing ring can not be taken out.
Additionally, valve is exposed in the air for a long time, especially in heavy rain weather, rainwater can be beaten on valve body wall, water and edge
The gap between sealing ring and valve seat enters, and subsequently contacts with sealing ring, and rainwater, therefore can be by sealing ring due to carrying acidity
Erode, decline the sealing ring life-span.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of compact conformation, integrally can take out
Sealing ring, the novel valve sealing ring of simple to operate, long service life.
The purpose of this utility model is achieved through the following technical solutions：A kind of novel valve sealing ring, it include sealing
Ring main body, sealing ring pedestal and plug cock, described sealing ring body normal in sealing ring pedestal and are fixed on sealing ring pedestal,
Runner A is provided with described sealing ring main body, in sealing ring pedestal, is provided with the runner B connected with runner A, sealing ring pedestal
Upper and lower surface on to be provided with around sealing ring main body be the cannelure I in the center of circle and cannelure, be provided with cannelure I O-shaped close
Seal, is provided with V-shaped seal ring in cannelure, be additionally provided with the ring for the center of circle around sealing ring main body in described sealing ring pedestal
Shape die cavity, is evenly distributed with multiple through holes, is provided with connected ring on the outer wall of sealing ring pedestal between annular die cavity and cannelure I
The plug cock of shape die cavity, the upper and lower side on the outward flange of described sealing ring pedestal positioned at sealing ring pedestal are respectively arranged with upper annular
Circle and lower annular ring, the top of upper annular ring and lower annular ring is provided with water storage tank.
Described upper annular ring is arranged parallel to lower annular ring.
The utility model has advantages below：The utility model compact conformation, integrally can take out sealing ring, operation letter
Single, long service life.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is further described, protection domain of the present utility model be not limited to
Lower described：
As shown in Fig. 1 ~ 4, a kind of novel valve sealing ring, it include sealing ring main body 1, sealing ring pedestal 2 and plug cock 3,
Described sealing ring main body 1 perpendicular to sealing ring pedestal 2 and is fixed on sealing ring pedestal 2, is set in described sealing ring main body 1
Runner A4 is equipped with, is provided with, in sealing ring pedestal 2, the runner B5 connected with runner A4, in the upper and lower surface of sealing ring pedestal 2 all
Cannelure I6 and cannelure 8 for the center of circle around sealing ring main body 1 is provided with, O-ring seal, cannelure are installed in cannelure I6
V-shaped seal ring is installed in 8, is additionally provided with described sealing ring pedestal 2 around the annular die cavity 7 that sealing ring main body 1 is the center of circle,
Multiple through holes 9 are evenly distributed between annular die cavity 7 and cannelure I6, are provided with connection annular on the outer wall of sealing ring pedestal 2
The plug cock 3 of die cavity 7.As shown in Figure 1 and Figure 4, the upper and lower side on the outward flange of sealing ring pedestal 2 positioned at sealing ring pedestal 2 is distinguished
Annular ring 10 and lower annular ring 11 is provided with, the top of upper annular ring 10 and lower annular ring 11 is provided with water storage tank 12, when
When upper valve base 13 and lower valve base 14 are exposed to rainwater weather, the rainwater descended slowly and lightly on 2 side wall of sealing ring pedestal is along base side wall
Fall and water storage tank 12 is collected in, penetrating in sealing ring along gap so as to effectively prevent rainwater, extending making for sealing ring
With the life-span, this outside upper annular ring 10 and lower annular ring 11 also act the effect for keeping off the rain and keeping off air particle.
Described upper annular ring 10 is arranged parallel to lower annular ring 11.
The course of work of the present utility model is as follows：Sealing ring main body is arranged in upper valve base 13, and by sealing ring pedestal
