| description | The utility model discloses a vertical lifting type check valve. A valve body is of an integral hollow cavity structure. The valve clack unit is located in a valve body hollow cavity in the upper portion of the valve base and provided with a sealing element with the outer contour capable of making contact with the valve body inclined face to seal the valve body. The valve base is matched and fixed with the inner wall of a cavity of the valve body at a bottom port of the valve body; the valve base is formed by connecting a middle hollow shaft with a plurality of radial support arms for separating medium flow channels; the valve rod is arranged in a middle hollow shaft of the valve base in a sliding mode and is coaxial with the valve body and the valve base. The fastening unit is circumferentially sleeved and fixed to the periphery of the top of the valve rod and makes contact with the upper surface of the valve clack unit in an abutting mode. According to the utility model, the problem of non-uniform stress of |
