Description
Technical field
This utility model is related to the technical field of seal ring structure, particularly a kind of valve body piece sealing ring.
Background technology
Seal ring seal is exactly to open a groove on two surfaces worked in coordination（According to sealing ring-shaped fluting）,
Sealing ring is inserted the inside, plays the effect of sealing.Seal ring seal purposes is widely.It is seen everywhere in daily life.Press
Sealing ring-shaped is divided and is had 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 of metal and rubber, carrys out the type from sealing ring by use environment and working pressure class.Typically
Low pressure using O-shaped sealing ring high pressure using U-shaped sealing ring.
Sealing between the valve body of wherein vertical setting and end cap generally adopts sealing ring to realize, vertical flowing in valve body
After medium is applied to end cap, the direction of motion of medium changes, and radial force increases, and leads to sealing ring to have the trend of lateral displacement,
There is static friction between sealing ring on sealing ring and the end face of valve body, wear-out failure occur, therefore singly end cap and valve body it
Between connect vertical screw and can not offset this radial force.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of compact conformation, long service life, consolidates
Fixed work, valve body piece sealing ring simple to operate.
The purpose of this utility model is achieved through the following technical solutions：A kind of valve body piece sealing ring, it includes sealing
Ring main body, sealing ring pedestal, described sealing ring body normal in sealing ring pedestal and is fixed on sealing ring pedestal, described
Be provided with runner A in sealing ring main body, in sealing ring pedestal, be provided with the runner B connecting with runner A, sealing ring pedestal upper and lower
Being provided with surface around sealing ring main body is the cannelure in the center of circle, and the both sides of described sealing ring pedestal are provided with level and set
The screwed hole put, screwed hole female thread is connected with threaded rod, and the other end of threaded rod is threaded with pressing plate.
Two described screwed holes are symmetrical arranged with regard to sealing ring pedestal.
Described pressing plate is rectangular-shaped or square shape.
Described pressing plate is arranged perpendicular to threaded rod.
In described cannelure, O-ring seal is installed.
This utility model has advantages below：This utility model compact conformation, long service life, fixed labor, operation letter
Single.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is the scheme of installation of this utility model and valve body；
In figure, 1- sealing ring main body, 2- sealing ring pedestal, 4- runner A, 5- runner B, 6- cannelure, 7- screwed hole, 8- spiral shell
Rasp bar, 9- pressing plate, 10- valve body, 11- end cap.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described：
As shown in Fig. 1 ~ 3, a kind of valve body piece sealing ring, it includes sealing ring main body 1, sealing ring pedestal 2, and described is close
Seal ring main body 1 perpendicular to sealing ring pedestal 2 and is fixed on sealing ring pedestal 2, is provided with runner in described sealing ring main body 1
A4, is provided with the runner B5 connecting with runner A4 in sealing ring pedestal 2, the upper and lower surface of sealing ring pedestal 2 is provided with around
Sealing ring main body 1 is the cannelure 6 in the center of circle, and the both sides of described sealing ring pedestal 2 are provided with horizontally disposed screwed hole 7,
Screwed hole 7 female thread is connected with threaded rod 8, and the other end of threaded rod 8 is threaded with pressing plate 9.
Two described screwed holes 7 are symmetrical arranged with regard to sealing ring pedestal 2；Described pressing plate 9 is rectangular-shaped or square shape；
Described pressing plate 9 is arranged perpendicular to threaded rod 8；In described cannelure 6, O-ring seal is installed.
Work process of the present utility model is as follows：Sealing ring main body 1 is arranged in valve body 10, and by sealing ring pedestal 2
It is installed between valve body 10 and end cap 11, mounting screw between valve body 10 and end cap 11, upper O-shaped sealing ring and valve body 10
Lower surface contacts, and lower O-type sealing ring is contacted with the inner surface of end cap 11, and precession pressing plate 9 makes valve body 10 and end cap 11 be fixed on
Between two pressing plates 9, after in valve body 10, conducting has liquid medium, liquid medium is fallen on this sealing ring from top to bottom, subsequently
Change direction and radially impact valve body 10, because two pressing plates 9 are applied with opposite direction radial force, two rightabout footpaths
Cancelling out each other to power, thus avoiding generation static friction between O-ring seal and valve body 10 and end cap 11, effectively extending whole
The service life of sealing ring.
