Threadless pipe coupler for sprinkler pipe |
摘要 |
A pipe coupler for use in fire sprinkler systems is of generally cylindrical shape. The coupler carries locking springs to engage grooves carried on the ends of the sprinkler pipes. The coupler also carries seal rings to provide for leak proof coupling. Each locking spring is carried in a groove in the coupler which has its sidewalls inclined to the inner surface of the coupler. Axial movement of the pipe in either direction relative to the coupler produces a wedging or camming action between the locking spring and the sidewall of the coupler groove and the sidewall of the pipe groove. |
