Abstract
The utility model is related to field of petroleum machinery, the specifically a kind of interior shoulder sealing ring of band for super-pressure gate valve；It is characterized in that：Including sealing ring body and convex hoop shape shoulder, the convex hoop shape shoulder is located in sealing ring body interior.This sealing ring has interior shoulder, interior shoulder can play a part of being oriented to and support when sealing ring is assembled, so as to avoid sealing ring from occurring displacement and inclination in assembling process, simultaneously, interior shoulder is located at the top or bottom of sealing ring body, by asymmetric position relationship, front and the reverse side of sealing ring body can be differentiated easily.
Description
Technical field
The utility model is related to field of petroleum machinery, the specifically a kind of interior shoulder sealing ring of band for super-pressure gate valve.
Background technology
With the growth of oil recovery technique, the use of well head fracturing technique is more and more extensive.And well head fracturing technique needs to make
With heavy caliber, high voltage bearing valve, in such a valve in use, conventional octagonal gasket ring easily gasket ring inclination occurs in assembling,
So as to cause whole valve to produce leakage, it is impossible to suitable for high pressure operating mode.
The content of the invention
The purpose of this utility model is to provide a kind of sealing ring with shoulder, and it is not in incline when loading gate valve
Tiltedly.
In order to achieve the above object, the utility model is realized in：
A kind of interior shoulder sealing ring of band for super-pressure gate valve, including sealing ring body and convex hoop shape shoulder, it is described convex
Annular shoulder is located in sealing ring body interior.
The described interior shoulder sealing ring of the band for super-pressure gate valve, the section of sealing ring body is rectangular, and surrounding is set
There is chamfering；The section of convex hoop shape shoulder is also rectangular, and convex hoop shape shoulder is located at the 1/3 of sealing ring body total height.
This sealing ring has interior shoulder, and interior shoulder can play a part of being oriented to and support when sealing ring is assembled, so that
Sealing ring is avoided to occur displacement and inclination in assembling process, meanwhile, interior shoulder is located at the top or bottom of sealing ring body, leads to
Asymmetric position relationship is crossed, front and the reverse side of sealing ring body can be differentiated easily.
Brief description of the drawings
Fig. 1 is the structural representation of this sealing ring.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
A kind of interior shoulder sealing ring of band for super-pressure gate valve, including sealing ring body 1 and convex hoop shape shoulder 2, it is described
Convex hoop shape shoulder 2 is located inside sealing ring body 1.
The described interior shoulder sealing ring of the band for super-pressure gate valve, the section of sealing ring body 1 is rectangular, and surrounding is set
There is chamfering 3；The section of convex hoop shape shoulder 2 is also rectangular, and convex hoop shape shoulder 2 is located at the 1/3 of the sealing total height of ring body 1.
This sealing ring has interior shoulder, and interior shoulder can play a part of being oriented to and support when sealing ring is assembled, so that
Sealing ring is avoided to occur displacement and inclination in assembling process, meanwhile, interior shoulder is located at the top or bottom of sealing ring body, leads to
Asymmetric position relationship is crossed, front and the reverse side of sealing ring body can be differentiated easily.
