More Information
Summary:The utility model relates to a check valve, in particular to an all plastic wafer check valve. The wafer check valve comprises a valve body and a valve plate; the valve plate is hinged on the valve body; and a seal ring is arranged on the working face of the valve plate. The wafer check valve is characterized in that the axial line of the articulated shaft of the valve plate and the working face of the valve body are positioned on the same plane. As the working face and the axial line of the articulated shaft are on the same plane, the seal ring of the valve body has uniform stress towards the working face of the valve body, and the seal effect is good.
