Claims (1)

[Scope of Claim for Utility Model Registration] This is a safety valve mainly attached to tanks for supplying high-pressure gas, etc., which is screwed onto one side of the base exterior pipe and spirally advances and retreats inward, and has a narrow end at the tip. A hollow pressure adjusting screw cylinder with a screw thread on the abutting part to the valve and the outer periphery of the diameter, and a hollow rear end side for making close contact with the relevant abutting part, and a true flat surface on the abutting side of the top surface. A cylindrical valve is formed in which a Teflon surface or a resin surface is fitted or glued, and a piece is provided at the tip of one side that supports the cylindrical valve, and a spring is attached to the periphery of the shaft, and a piece that fits into both ends of the spring is formed. an elongated receiving shaft each equipped with a washer that serves as a stopper; a piece at the tip of the receiving shaft and a part for housing the cylindrical valve supported by the piece in the interior so as to be movable back and forth by pressure. A bulging nut part is provided at the side end, small holes are provided at multiple locations on the upper side of the nut part to release excessively high pressurized pressure, and a flange part is provided at the other end part that narrows slightly toward the inner circumference. A guide cylinder is formed, and the piece at the tip of the bearing shaft is placed against the hollow part of the cylindrical valve, and the washer serving as the stopper on the side that comes into contact with this piece is locked from the nut side to the flange in the guide cylinder. In addition, the nut portion of the guide tube is screwed to the screw thread on the outer periphery of the narrow diameter abutting portion of the pressure adjusting screw tube, so that the cylindrical valve is enclosed within the guide tube. This device is assembled into the interior of the exterior tube so that the exhaust port provided in the base exterior tube and the small pressure relief holes provided at multiple locations in the guide tube are located at the same location. A valve device for a safety valve characterized by the following.
