Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings. like figure 1 , 2 , 3, there is a sealing groove 6 on the flange body 2, and the sealing groove 6 and the gasket 5 cooperate with each other to make the sealing effect very good. Fixed connection, good fixing effect, good sealing effect, and suitable for high-pressure operation, the annular groove 7 is opened on the inner side of the flange, and there are three annular grooves 7 on the flange body 2, and the annular groove 7 is concentric with the pipe 4 as the center Distributed in a circle, the cross-sectional shape of the annular groove 7 is an isosceles triangle. The flange body 2 is provided with reinforcing ribs 1 to strengthen the connection between the flange and the pipeline 4, so that the pressure resistance is strong, the sealing effect is good, and it is difficult to leak, which is suitable for harsh working occasions. The flange can not only be operated u...

Abstract

The invention relates to a compression-resisting sealing flange which is formed by a flange body, reinforcing ribs, bolt holes, a pipeline, a sealing gasket, a sealing groove and an annular groove. The flange body is provided with a plurality of bolt holes evenly distributed. The reinforcing ribs are welded and evenly distributed on the flange body every 90 degrees. The center of the flange body is provided with a pipeline hole. The inner side of the flange body is provided with the annular groove. The end of the flange body is provided with the sealing groove and the sealing gasket. The sealing gasket is made of corrosion resistant materials and is arranged at the end of the flange body and matched with the seal groove formed in the end of the flange body so as to reach a double sealing effect. The upper inner side of the flange body is provided with three annular grooves which are distributed as concentric circles with the pipeline as the center, and the cross section of each annular groove is of an isosceles triangle shape. The seal groove in the flange body is matched with and interacts with the sealing gasket. The flange body is provided with the reinforcing ribs, so operations can be carried out on the condition of high pressure and a good sealing effect is achieved. Consequently, work efficiency is improved, operating cost is reduced, and the compression-resisting sealing flange is applicable to harsh working occasions and is stable in operation, simple in structure and convenient to manufacture.

Description

technical field [0001] The invention relates to a pressure-resistant sealing flange, in particular to a pressure flange in a pipeline connector, and belongs to the field of pipeline connection design. Background technique [0002] The pressure-resistant sealing flange is a kind of pipe connection with good pressure resistance and strong sealing ability through the design of the flange body structure. The purpose of anti-compression; through the design of annular grooves, sealing grooves and gaskets, the sealing effect of the flange is significantly improved, and the structural design makes the flange both anti-compression and sealing performance. Most of the current flanges use a flat pressing surface structure. The bond between the flange and the flanged pipe of this structure is low, and the pre-tightening effect is not good, which is easy to cause high-pressure materials in the pipeline. , The sealing gasket is easy to be squeezed out to compress the sheet, and the seali...
