Further, be equipped with on the hand wheel with the communicating polygon through-hole of polygon recess, two outsides of polygon recess lower extreme articulate through the articulated shaft has the shrouding that can cover the polygon recess, the cover is equipped with the torsional spring on the articulated shaft, and torsional spring one end is supported at hand wheel lower extreme, the other end and is supported at the shrouding lower extreme, be equipped with the limiting plate on the articulated shaft.

Furthermore, the outer side of the lower part of the hand wheel is provided with a step inserted into the valve cover, and the upper end of the valve cover is provided with a limiting ring which is bent inwards and can be abutted against the surface of the step.

Furthermore, a plug is inserted at the upper end of the polygonal through hole.

Further, the upper end of the valve rod is rotated to penetrate through a rotating shaft penetrating through the through groove, the polygonal linkage block is fixed to the rotating shaft, a polygonal slot is formed in one end of the rotating shaft, and a through hole capable of being aligned to the polygonal slot is formed in the valve cover.

Furthermore, the bottom of the polygonal linkage block is arc-shaped.

After the technical scheme is adopted, when the stop valve needs to be opened and closed, the polygonal linkage block is inserted into the polygonal groove, the hand wheel is rotated at the moment, the polygonal linkage block, the valve rod and the valve clack can be driven to move up and down, the purpose of opening and closing the stop valve is achieved, when the polygonal linkage block is separated from the polygonal groove, the hand wheel is rotated, the valve cannot be opened and closed, misoperation is effectively prevented, and the use safety is higher.
