Abstract
The utility model discloses a connecting flange of a valve. The connecting flange of the valve comprises a flange disc, through holes are formed in the middle of the flange disc, step grooves are arranged at four sides of the through holes, slope faces are arranged at the inner walls of the through holes, seal rings are arranged on the inner walls of the through holes, edges all around the flange disc are provided with bolt holes, and cone-shaped faces matched with the inner walls of the through holes are arranged on the seal rings. The connecting flange of the valve is firm in connection and good in sealing performance.
Description
Technical field
The utility model relates to a kind of valve adpting flange.
Background technique
In the existing technology, the valve adpting flange is widely used in the pipeline industry, but in general pipeline connection procedure, if pipeline does not arrange flange in advance, just is difficult to connect, and so just is difficult to connect, and easily occurs leaking.
The model utility content
The utility model provides a kind of pipeline that can make things convenient for the pipeline oral area that flange is not set to dock, the valve adpting flange of good airproof performance.
The utility model technical solution problem provides following scheme:
A kind of valve adpting flange comprises flange plate, it is characterized in that: the middle part of described flange plate is provided with through hole, is provided with stepped slot around the described through hole, and the inwall of described through hole is provided with slope, and the inwall of described through hole is provided with seal ring.
Be provided with bolt hole around the edge of described flange plate, described seal ring has a conical surface that matches with through-hole wall.
The utility model is provided with through hole at the center of flange on traditional flange basis, add seal ring in through hole, and the inwall of through hole is provided with the inclined-plane, cooperates conical seal ring is installed, and has effectively avoided the leakage at pipe joint place.
