The invention discloses a novel one-way valve. The novel one-way valve comprises a valve body, flow dividing plates, a valve inlet, and a valve outlet, the middle of the valve body is designed in a hollow manner, the valve inlet and the valve outlet are sequentially formed in the direction of the valve body and correspond to each other, the flow dividing plates are welded in the position, close tothe valve inlet, in the valve body, and divide the valve inlet into an upper part, a middle part and a lower part, sizes of branch tubes of the three parts are the same, outlets of the branch tubes communicate with the valve outlet, the outlet is in a hopper shape, springs are welded to outlets of the branch tubes on the upper part and the lower part, the free ends of the springs are welded withrubber plugs, a shaft connection baffle is arranged in the branch tube of the middle part, a stop block is welded to the baffle in the vertical direction, and a screw rod is arranged on the stop blockin the vertical direction. The valve is simple in structure and reasonable in design, the flow dividing plates can carry out flow dividing on the fluid, the vibration to the valve body due to fluid impact force can be reduced, the screw rod can carry out flow adjusting, and the valve is suitable for use and popularizing.
