Abstract
The utility model discloses an inert gas sealing flange, including the flange body, be equipped with interior bulge loop and evagination ring on the butt joint face of flange body, be formed with annular bin groove including flange body and connecting piece are connected the back between bulge loop and the evagination ring, be equipped with the inlet port on the evagination rampart inlet port department is connected with the intake pipe that lets in inert gas to annular bin inslot. The utility model discloses a set up inside and outside bulge loop on flange body butt joint face, form annular bin groove including after the flange joint between the inside and outside bulge loop, then let in inert gas through the inlet port on the outside bulge loop to play sealed effect, the utility model discloses an inert gas seal flange cost of manufacture is low, simple workable, can satisfy the sealed requirement of low pressure again.
Description
Technical Field
The utility model relates to a flange technical field specifically is an inert gas seals flange.
Background
The flange is the connecting parts commonly used for equipment connection, in some fields especially chemical industry field, need use some not highly to the pressure requirement, but to the special-shaped flange that sealing performance required is very high, and outsourcing standard flange often can not all satisfy above-mentioned requirement, consequently, needs a cost of manufacture low, simple workable, can satisfy the flange spare that the low pressure sealed required again urgently, avoids the standard flange can not satisfy the awkwardness of above-mentioned all requirements in a flexible way.
Disclosure of Invention
An object of the utility model is to provide a can nimble application in special occasion, process on the spot, can satisfy the inert gas sealing flange that the sealed process units of low pressure required again.
The utility model adopts the technical scheme as follows: an inert gas sealing flange comprises a flange body, wherein an inner convex ring and an outer convex ring are arranged on the butt joint surface of the flange body, an annular bin groove is formed between the inner convex ring and the outer convex ring after the flange body is connected with a connecting piece, an air inlet hole is formed in the wall of the outer convex ring, and an air inlet pipe for introducing inert gas into the annular bin groove is connected to the air inlet hole.
Further, the wall thickness of the outer convex ring is larger than that of the inner convex ring.
Furthermore, the inner convex ring, the outer convex ring and the flange body are welded or integrally formed.
Further, including two flange bodies of butt joint, all correspond on the butt joint face of two flange bodies and be equipped with interior bulge loop and outer bulge loop, be equipped with sealed the pad between two flanges, be formed with annular bin groove respectively on two flanges after two flange joint.
Furthermore, the sealing gasket in the annular bin groove is provided with an air vent, and the outer convex annular wall of one flange is provided with an air inlet.
The utility model discloses a set up in the flange body butt joint face, the evagination ring, including behind the flange joint, form annular bin groove between the evagination ring, then let in inert gas through the inlet port on the evagination ring, when the inside flange department is revealed to the inside emergence of the affiliated pipeline of flange, it is inert gas at first to get into, outside air is separated can not get into inside the pipeline, thereby play sealed effect, and in the same way, when inert gas pressure is higher than the affiliated pipeline internal pressure of flange, at first outside reveal be inert gas, pipeline inside gas is separated can not reveal in the pipeline. The utility model discloses an inert gas seal flange cost of manufacture is low, simple workable, can satisfy the sealed requirement of low pressure again.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
To facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the specific embodiments described below.
As shown in fig. 1, the inert gas sealing flange of the present embodiment includes two flange bodies 1 that are butted, an inner collar 2 and an outer collar 3 are correspondingly disposed on the butted surfaces of the two flange bodies 1, a sealing gasket 4 is disposed between the two flanges, annular bin slots 5 are respectively formed on the two flanges after the two flanges are connected, air inlet holes 6 are disposed on the walls of the outer collar 3, and air inlet pipes for introducing inert gas into the annular bin slots 5 are connected to the air inlet holes 6.
In specific implementation, the inner convex ring 2, the outer convex ring 3 and the flange body 1 can be welded or integrally formed, and the wall thickness of the outer convex ring 3 is greater than that of the inner convex ring 2.
In specific implementation, the sealing gasket 4 in the annular bin groove 5 can be provided with air holes, and the outer convex annular wall of one flange is provided with an air inlet hole.
The utility model discloses a flange of the sealed form of inert gas carries out sealing connection, and it can be used in special occasion in a flexible way, processes on the spot, can satisfy the sealed requirement of low pressure again, and the solution of sealed problem has just solved a lot of because sealed problem and can not design the equipment of preparation and also can carve the problem on the horse promptly, increases the variety of the nimble preparation of equipment, promotes new equipment, and the development of new trade has the realistic meaning that can not estimate.
Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
