Abstract

The invention discloses a stainless steel butt welding ring loose sleeve flange, and relates to the technical field of loose sleeve flange. The flange comprises a positioning sleeve body and a fixed sleeve body. The inner of both the positioning sleeve body and the fixed sleeve body are provided with fixing holes. Fixing bolts are arranged in the inner the fixing holes. The outer of the fixing bolts is connected with fixing nuts in a threaded mode. A limit groove is formed on the side of the positioning sleeve close to the fixed sleeve body. A limit board is arranged in the limit groove. The positioning sleeve is fixedly connected to the middle of the limit board. The fixing bolts and fixing nuts can be arranged to fit the positioning sleeve body and the fixing sleeve body, so that the limit board can be fixedly arranged in the limit groove, and the positioning sleeve can be easily disassembled and assembled. A sealing ring can prevent the flange from leaking, and the flange can be connected with a connecting pipe through an external thread. When disassembling, the connecting pipe and the flange can be separated by only turning the positioning sleeve, thereby improving the practicability of the flange.

Description

technical field [0001] The invention relates to the technical field of loose flanges, in particular to a stainless steel butt welding ring loose flange. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between pipes and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw connection) flanges, weldi...
