Summary:The embodiment of the utility model provides a stop check valve with an operating hand wheel located on the side face of the valve, and relates to the technical field of ship pipeline accessories. Theproblem that a stop check valve in the prior art is not easy to operate is solved. Horizontal rotation of a valve operation hand wheel is converted into vertical rotation motion of a valve rod nut through transmission of a turbine and worm mechanism of a turbine and a worm on the upper portion of the valve rod nut. Through transmission of threads on the lower portion of the valve rod nut and a threaded mechanism of the threaded connecting rod, vertical rotary motion of the valve rod nut is converted into vertical motion of the threaded connecting rod, and the threaded connecting rod moves inthe internal space of the valve. The threaded connecting rod is fixedly connected with the valve rod and drives the valve rod to move up and down, so that the valve rod compresses or loosens the valvedisc; when the medium flow
