Abstract
The utility model discloses a flange joint for a gas pipeline under pressure. The flange joint comprises two joint bodies, a left flange and a right flange, wherein the center of each joint body is provided with a through hole. When the two joint bodies are in butt joint, the left end and the right end are pipeline connecting ports. Circular grooves are arranged in adjacent end faces of the left joint body and the right joint body. A sealing ring is arranged in each circular groove. The outer wall of each joint body is provided with a boss. The two joint bodies are fixedly connected together through the left flange and the right flange. The bosses on the two joint bodies are correspondingly clamped in a clamping groove of the left flange and in a clamping groove of the right flange. The flange joint for the gas pipeline under pressure is reasonable in structure, convenient to use and good in tightness.
Description
Technical field
The utility model relates to a kind of pressurized gas line flanged joint.
Background technique
The flange arrangement form is varied, and most flanges connects as flange docking in the left and right sides connects, and at the docking end face seal ring assurance sealing is set, but because the life-span of seal ring is limited, use causes leaking easily for a long time.
The model utility content
It is a kind of rational in infrastructure, easy to use that the utility model provides, the pressurized gas line flanged joint of good airproof performance.
The utility model technical solution problem provides following scheme:
A kind of pressurized gas line flanged joint, comprise two fittings bodies, left and right flanges, it is characterized in that: the center of described two fittings bodies is provided with through hole, left and right two ends are pipeline connection port during described two fittings bodies docking, the adjacent end face of described left and right two joints is provided with annular groove, be provided with seal ring in the described annular groove, the outer wall of described fittings body is provided with boss, described two fittings bodies are fixed together by left and right two flanges, and described two fittings body boss are connected in the draw-in groove of left and right flanges.
Described left and right flanges links together by screw bolt and nut.
Outer double-layer structure in the utility model adopts, the draw-in groove that forms by the left and right flanges docking is fixed together fittings body, and structure is more firm, good airproof performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
