| description | The invention relates to a buffering type safety valve. The buffering type safety valve comprises a valve body, a valve base, a valve clack, a valve rod and a spring. The buffering type safety valve is mainly characterized in that a fixing base is arranged in the center of a channel of the valve base, and the lower end of the valve rod is fixedly installed in an inner hole of the fixing base. Thevalve clack is of an inverted-barrel type structure, a sealing face is arranged on the cylindrical end face of the lower end of the valve clack, and the center of the upper end face of the valve clackand the valve rod are in dynamic sealing fit. The spring is installed between the upper end of the valve clack and a spring compression cover. A circular guide ring is fixedly installed on the portion, located in an inner cavity of the valve clack, of the valve rod, a piston cavity is formed between the upper end face of the circular guide ring and the lower end face of the valve clack, and flowdrainage holes are formed i |
