Abstract
The utility model discloses a mass-flow spherical stop valve used under a coal mine. The mass-flow spherical stop valve used under the coal mine comprises a valve body assembly, a spherical valve core and a rotating mechanism, the spherical valve core is installed inside the valve body assembly, and the spherical valve core is connected with the rotating mechanism. The rotating mechanism comprises a valve rod, a worm gear, a worm and a handwheel, one end of the valve rod is fixed with the spherical valve core, the worm gear is fixed on the valve rod, the front end of the worm is meshed with the worm gear, and the handwheel is installed at the rear end of the worm. The mass-flow spherical stop valve used under the coal mine has the advantages that when the spherical stop valve is positioned in a closed state, and on the condition that large pressure difference exists on two sides of the spherical valve core placed inside a hydraulic channel, the pressure difference is 35.1 mega pascals usually, the spherical valve core inside the spherical stop valve bears large pressure, the spherical stop valve is not easy to open, and the handwaheel is labor-saving to pull by means of the lever principle.
Description
Technical field
The utility model relates to a kind of ball check valve, especially relates to a kind of for the large flow ball check valve under the coal mine.
