Split flapper check valve including a torsion spring wear reduction mechanism |
摘要 |
<p>A split flapper check valve (100) includes a torsion spring (112) wear reduction mechanism. In particular, the valve includes a pair of bushings (114) on a shaft (104) to which a pair of valve plates (108) is rotationally mounted. A torsion spring (112) is also mounted on the shaft (104) and is configured to bias the valve plates (108) toward a closed position. The wear reduction mechanism is implemented using a pair of bushings (114) that are disposed between the shaft (104) and the torsion spring (112).</p> |
