Abstract

The utility model discloses a pipeline connection flange which comprises a flange body. A through hole is arranged at the center of the flange body, a connector pipe is arranged on the periphery of a mouth of the through hole, a step groove is arranged on the end face of the flange body, a seal ring is embedded in the step groove, and a plurality of bolt installation holes are formed in the periphery of the connector pipe of the flange. The pipeline connection flange is firm to connect and good in seal performance.

Description

Pipeline coupling flange
Technical field
The utility model relates to the link of pipe fitting, specifically a kind of pipeline coupling flange.
Background technique
Flange plate is applied to pipeline and connects, and the end face of the flange plate in the existing technology all is circular planes shape, because two flange plate abutting joints together, at present, in actual production, can cause the pipeline connecting staggered, causes sealing effect bad.
The model utility content
The utility model provides a kind of and is connected firmly, the pipeline coupling flange of good airproof performance.
The utility model technical solution problem provides following scheme:
A kind of pipeline coupling flange comprises flange body, it is characterized in that: the central authorities of described flange body are provided with through hole, are provided with mouthpiece around the oral area of described through hole, and the end face of described flange plate is provided with stepped slot, is inlaid with seal ring in the described stepped slot.
Be provided with a plurality of bolt mounting holes around the mouthpiece of described flange plate.
The utility model is installed seal ring in the stepped slot around the through hole in the middle of will flange plate in use, and like this because the design of stepped slot, the error that has produced when effectively having avoided the flange docking between the pipeline causes pipeline to connect leakage, has improved sealing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of pipeline coupling flange, comprise flange body 1, the central authorities of described flange body 1 are provided with through hole 2, be provided with mouthpiece 3 around the oral area of described through hole 2, the end face of described flange body is provided with stepped slot 4, is inlaid with seal ring 5 in the described stepped slot 4, is provided with a plurality of bolt mounting holes 6 around the mouthpiece of described flange body 1.

Claims (2)
