Abstract
The utility model relates to a seal structure technical field just discloses seal structure that high pressure barrel is connected, including first barrel and through the second barrel of bolt fixed mounting in first barrel one side, the cover is equipped with the sealing ring between first barrel and the second barrel. This seal structure that high pressure barrel is connected, cross section through with the sealing ring sets up to the concave type and can increase the area of contact between sealing plug and the barrel and be difficult for expanding to the outside in the time, make the pressure distribution of the contact surface between sealing ring and the barrel comparatively even, improve the sealed effect of sealing ring, cooperation through first gas pocket and second gas pocket is used, make RTV glue can be even fill in sealing mechanism's inside, and then seal the clearance that the contact surface between the sealing ring pressurized back and the barrel produced, improve sealing mechanism's leakproofness, it is convenient for glue RTV to fill to seal structure inside to utilize the sealing plug to seal when can sealing first gas pocket.
Description
Technical Field
The utility model relates to a seal structure technical field specifically is the seal structure that high-pressure barrel connects.
Background
When connecting between the partial high pressure barrel that has now, the majority directly adopts the sealing ring to seal, nevertheless because the area of contact between sealing ring and side inner and outer annular surface and the high pressure barrel is less, lead to the sealing ring to expand to the outside easily, and then the pressure distribution of the contact surface between sealing ring and the barrel is not enough even, lead to the sealed effect of sealing ring relatively poor, simultaneously the sealing ring pressurized after can and the contact surface between the barrel produces the clearance, influence the sealed effect between the barrel.
SUMMERY OF THE UTILITY MODEL
Not enough to the background art, the utility model provides a seal structure that high-pressure barrel is connected has solved the problem that above-mentioned background art provided.
The utility model provides a following technical scheme: the sealing structure for the connection of the high-pressure barrel comprises a first barrel and a second barrel fixedly installed on one side of the first barrel through a bolt, a sealing ring is sleeved between the first barrel and the second barrel, and two sealing plugs are symmetrically distributed on a threaded socket on one side of the first barrel.
Preferably, two first air holes which are symmetrically distributed and are positioned on the inner side of the sealing ring are formed in the first cylinder.
Preferably, the cross section of the sealing ring is concave, and RTV sealant is filled in the concave.
Preferably, one side of the second cylinder, which is close to the first cylinder, is provided with a positioning column.
Preferably, a second air hole is formed in the sealing ring.
The utility model discloses possess following beneficial effect:
1. this seal structure that high pressure barrel is connected sets up the cross section through with the sealing ring into the area of contact that concave type can increase between sealing plug and the barrel and be difficult for the inflation to the outside in for the pressure distribution of the contact surface between sealing ring and the barrel is comparatively even, improves the sealed effect of sealing ring.
2. This seal structure that high pressure barrel is connected uses through the cooperation in first gas pocket and second gas pocket for RTV glues the inside of filling at sealing mechanism that can be even, and then seals the clearance that the contact surface between the sealing ring pressurized back and the barrel produced, improves sealing mechanism's leakproofness, utilizes the sealing plug to be convenient for glue RTV and fill to seal structure inside when can sealing first gas pocket.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model provides an in the attached drawing: the different types of hatching in the figures are not given the national standards, do not require the material of the elements, and distinguish between cross-sectional views of the elements in the figures.
Referring to fig. 1-3, the sealing structure for connecting high-pressure cylinders includes a first cylinder 1 and a second cylinder 3 fixedly mounted on one side of the first cylinder 1 by bolts 2, a sealing ring 4 is sleeved between the first cylinder 1 and the second cylinder 3, and two sealing plugs 5 symmetrically distributed are arranged on a threaded socket on one side of the first cylinder 1.
Wherein, two first air holes which are symmetrically distributed and are positioned at the inner side of the sealing ring 4 are arranged in the first cylinder 1.
Wherein, the cross section of sealing ring 4 is concave type, and the sealed glue of RTV is filled to concave type inside.
Wherein, one side that second barrel 3 is close to first barrel 1 is provided with the reference column, utilizes the reference column to prevent to produce the dislocation between first barrel 1 and the bolt 2 when can fixing a position first barrel 1, and then influences the leakproofness of sealing ring 4.
Wherein, the inside of sealing ring 4 is provided with the second gas pocket, utilizes the second gas pocket to carry RTV to the junction of second barrel 3 and sealing ring 4, and then seals the clearance between second barrel 3 and the sealing ring 4.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
