Valve type check valve

A valve type check valve comprises a valve body, the two ends of the valve body are correspondingly connected with a connector pipe and a conversion connector in a sealed mode respectively, two channels penetrating through the valve body are symmetrically formed in the end face of the valve body, and an installation arm is reserved between the two channels at the end, facing the conversion connector, of the valve body. Two valve turning plates used for sealing the two channels of the valve body respectively are hinged to the positions corresponding to the mounting arms, torsion springs used for closing the valve turning plates are arranged at the hinged positions of the valve turning plates and the mounting arms, and limiting structures used for preventing the two valve turning plates from colliding are arranged on the plate faces, deviating from the channels of the valve body, of the two valve turning plates. Compared with a traditional steel ball type one-way valve, the valve turning plate is in surface con
