A sealing gasket, a tightening device for the gasket, and a stopper device for limiting the rotation range of the valve shaft are provided in the upper cover, and an operating connection portion is further provided at the outer tip of the valve shaft outside the upper cover. A valve characterized by forming. (2) The shaft sealing packing consists of a self-sealing packing that performs a sealing action by the pressure of the fluid inside the valve, and a tightening packing that performs a sealing action by tightening. Valves listed in section. (3) Registration of a utility model in which the self-sealing type packing is provided on the inner side of the valve from the bearing part of the valve stem, and the tightening type packing is provided on the outer side of the valve from the bearing part of the valve stem. The valve according to claim 2. (4) A request for registration of a utility model in which the self-sealing packing is provided on the inner and outer sides of the valve from the bearing part of the valve stem, and the tightening packing is provided on the outer side of the valve. 2. The valve according to item 2. (5) The valve according to claims 3 and 4 of the utility model registration claim, which is provided with a grease injection device for injecting grease into the bearing portion. (6) The valve according to claims 2 to 5, wherein the self-sealing packing is an O-ring. (7) The retightening device is a utility model consisting of a nut that is screwed onto a male thread formed on the valve shaft and has a locking device, and a cylindrical gland installed between the nut and the tightening type packing.
