The utility model relates to a new type of double-regulating switch valve, which comprises a valve body, a valve seat and a valve cap. The valve body is equipped with a spherical valve core. The upper end of the spherical valve core is connected with a valve stem, and the top of the valve stem is connected with a rotary handwheel. The two ends of the spherical valve core are connected with a vertical cutting surface. There is a flow passage between the two vertical cutting surfaces. The center of the spherical valve core is provided with a baffle installation groove along the vertical direction. The bottom of the installation groove is lower than the bottom of the flow passage. The top of the baffle installation groove is connected with the bottom of the valve stem. There are through grooves inside the valve stem. There are pull rods in the groove. The bottom of the pull rod is connected with a baffle. The top of the pull rod is connected with a lifting handwheel. There are connecting devices between the lifting handwheel and the rotating handwheel. The utility model can not only use revolving handwheel to drive the rotation of valve stem and spherical valve core to realize opening and closing, but also use lifting handwheel pull rod and baffle to realize opening and closing, so as to avoid excessive wear of spherical valve core by single opening mode and prolong the service life of the switch valve.
