Description
Technical Field
The utility model relates to the technical field of flat welding flanges, in particular to a flat welding backing ring flange with a free end having a strength.
Background
The flat welded flange is generally referred to as a flat plate, and is also called a lap welded flange. The connection between the flat welding flange and the pipeline is that the pipeline is firstly inserted into the inner hole of the flange to a proper position and then lap welding is carried out. The flat welding flange is suitable for pipeline systems with low pressure grade and less serious pressure fluctuation, vibration and oscillation. The flat welding flange has the advantages that the flat welding flange is easy to center during welding and assembling, and the price is low, so the flat welding flange is widely applied. However, it is tired every day, under rugged environment, there is the not hard up problem of connection in the bolt on the flange, can appear the bolt even and drop, and the flange influences normal work with the circumstances such as connecting piece is not hard up, when adopting welded connection moreover, the flange corrodes with the junction of body easily.
To this end, we propose a flat welded liner ring flange with a free end bearing a force.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a flat welding backing ring flange with a free end having strength, which can effectively solve the problems in the background technology.
In order to achieve the purpose, the utility model adopts the technical scheme that:
a flat welding backing ring flange with a free end strength comprises a flange chassis, a flange neck platform and a backing ring sleeve, wherein the flange neck platform is connected to the top of the flange chassis, an inner edge is formed on the inner wall of the flange chassis, and the backing ring sleeve is sleeved on the outer side of the inner edge;
the inner periphery of the lining ring sleeve is provided with anti-skid grains, the side wall of the lining ring sleeve is attached to the bottom of the flange chassis, the side wall of the lining ring sleeve is provided with a through hole, and a fixing stud in threaded connection with the flange chassis penetrates through the through hole;
the inner periphery of the bushing sleeve is provided with an inclined surface.
Furthermore, a plurality of bolt through holes are formed in the top of the flange chassis and distributed in an annular array; so as to connect and fix the adjacent flange chassis.
Further, the top of the flange chassis is provided with an annular groove; the annular groove can be filled with a rubber pad, so that the sealing property between the flange base plate and the pipeline is improved.
Furthermore, the flange chassis and the flange neck platform are of an integrally formed structure; the whole structure is higher in strength and more durable.
Further, the inner diameter of the flange chassis is equal to that of the flange neck platform in size; the pipeline can conveniently pass through the flange chassis and the flange neck platform.
Compared with the prior art, the utility model has the following beneficial effects: the lining ring sleeve can improve the attaching effect between the flange chassis and the pipeline, and the inclined surface of the inner circumference structure of the lining ring sleeve enables the pipeline not to fall off easily after the pipeline passes through the flange chassis and the flange neck platform; through the annular groove that sets up, be convenient for fill the rubber pad to improve the leakproofness between pipeline and the flange chassis.
