Summary:PROBLEM TO BE SOLVED: To provide a swing type check valve having a regulating function and facilitating maintenance. SOLUTION: The swing type check valve included a valve box 1 having an opening part 7 formed thereon, a valve cover 8 detachably disposed on the valve box 1 and covering the opening part 7, and a valve element 5 capable of rotating through a valve shaft 4 supported on the valve box 1. The check valve opens and closes a channel passing through an inside of the valve box 1 by turning between a close position where the valve element 5 is seated on a valve seat 6 and an open position where the valve element separates from the valve seat. The check valve includes a stopper 10 abutting on a back surface at an opposite side of a surface of the valve seat 6 on which the valve element 5 is seated. The stopper 10 is movably installed on the valve cover 8, and opening of the valve element 5 is changed by movement of the stopper 10. COPYRIGHT: (C)2011,JPO&INPIT
