Abrégé
(EN)
A check valve that can be used even under high temperature conditions is provided as a result of improving heat resistance and solving the problem of "the stopper sticking to the sealing member" that is associated with high temperature use. The opening of a fluid channel (2a) provided in a first body (2) is blocked by a stopper (5), which is compelled by a compelling member (7), coming into contact with a sealing member (4). The sealing member (4) is a post-cured perfluoro elastomer packing. A ring-shaped sealing part (6) that contacts the sealing member (4) in a line is formed on the stopper (5).

本发明提供一种止回阀,提高耐热性并且解决了伴随高温使用而导致“栓体向密封构件的粘附”的技术课题,由此在高温条件下也能够使用。通过使被弹压构件(7)弹压的栓体(5)与密封构件(4)抵接而使设置在第1阀体(2)上的流体通路(2a)的开口成为关闭状态。密封构件(4)为进行了二次硫化的全氟橡胶制密封垫。在栓体(5)上形成有与密封构件(4)线接触的环状的密封部(6)。
