Abstract

A slurry-free flanging device comprises a flange plate, and is characterized in that a groove is arranged at the inner diameter position of the plate face of a flange plate, a seal ring is arranged inside the groove, and the inner diameter of the seal ring is larger than the inner diameter of the flanging plate. According to the slurry-free flanging device, due to the fact that the seal ring is arranged inside the groove and the inner diameter is greater than the inner diameter of the flanging plate, the seal ring is not enabled to protrude caused by the pressure outward when flanges are connected, and blocking at the connecting position of pipelines is avoided. The slurry-free flanging device is simple in structure and good in effect.

Description

Exempt from the hanging flange apparatus
Technical field
The utility model relates to the jointing of pipeline, specifically a kind of hanging flange apparatus of exempting from.
Background technique
Pipeline often adopts flange to connect, and for Leakage prevention, the seal ring fluid is set in the easily stagnant resistance of the joint of pipeline in the joint of flange, and having used of a specified duration can blockage phenomenon.
Summary of the invention
The purpose of this utility model be propose a kind of prevent from stopping up exempt from the hanging flange apparatus.
The purpose of this utility model is achieved in that a kind of hanging flange apparatus of exempting from of the present utility model, it comprises flange plate, it is characterized in that having groove in the card inner radius of flange plate, be provided with seal ring in the groove, the internal diameter of seal ring is greater than the internal diameter of flange plate.
The hanging flange apparatus of exempting from of the present utility model, owing to have groove in the card inner radius at flange plate, be provided with seal ring in the groove, the internal diameter of seal ring is greater than the internal diameter of flange plate, when connecting, flange can owing to impacting force causes the seal ring evagination, not avoid the obstruction that causes at pipeline junction.The utlity model has simple in structure, effective characteristics.
Description of drawings
Fig. 1 is structural representation of exempting from the hanging flange apparatus of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of hanging flange apparatus of exempting from, it comprises flange plate 1, it is characterized in that having groove in the card inner radius of flange plate 1, is provided with seal ring 2 in the groove, the internal diameter of seal ring 2 is greater than the internal diameter of flange plate 1.
