Abstract: A check valve includes a valve body, a pair of stoppers, a hinge pin, and one or more flappers. The valve body includes an inlet end, an outlet end, and an inner surface that defines a flow passage between the inlet end and the outlet end. The inner surface further defines a valve seat adjacent the inlet end. The stoppers are integrally formed on the valve body inner surface, and each has a first end and a second end. The hinge pin is disposed within each hinge pin opening and extends across the flow passage. The flappers are disposed within the flow passage and are rotationally mounted on the hinge pin. Each of the one or more flappers is rotatable between a closed position, in which the flapper engages the valve seat, and a full-open position, in which the flapper engages the pair of stoppers.

Abstract translation: 止回阀包括阀体，一对止动件，铰链销和一个或多个挡板。 阀体包括入口端，出口端和限定入口端和出口端之间的流动通道的内表面。 内表面还限定邻近入口端的阀座。 止动件一体地形成在阀体内表面上，并且每个具有第一端和第二端。 铰链销设置在每个铰链销开口内，并延伸穿过流动通道。 刮板设置在流动通道内并且旋转地安装在铰链销上。 所述一个或多个襟翼中的每一个可在关闭位置（其中所述挡板接合所述阀座）和完全打开位置之间旋转，所述挡板接合所述一对挡块。
