Abstract

The utility model discloses a pipeline connecting flange which comprises a flange body, wherein a through hole is formed in the center of the flange body, port pipes are arranged on the periphery of the opening of the through hole, a ladder-shaped groove is formed in the end face of the pipeline connecting flange, a sealing ring is embedded in the ladder-shaped groove, protrusions are arranged on the periphery of the pipeline connecting flange, a plurality of bolt installing holes are formed in the peripheries of the interface pipes of the pipeline connecting flange. The pipeline connecting flange has the advantages of being tight in connection and good in sealing performance.

Description

The pipeline coupling flange dish
Technical field
The utility model relates to the link of pipe fitting, specifically a kind of pipeline coupling flange dish.
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 dish of good airproof performance.
The utility model technical solution problem provides following scheme:
A kind of pipeline coupling flange dish comprises flange body, it is characterized in that: the central authorities of described flange body are provided with through hole, be provided with mouthpiece around the oral area of described through hole, the end face of described flange plate is provided with stepped slot, is inlaid with seal ring in the described stepped slot, and the edge of described flange body is provided with projection.
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 dish, 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, the edge of described flange body 1 is provided with projection 7, is provided with a plurality of bolt mounting holes 6 around the mouthpiece of described flange body 1.

Claims (2)
