Abstract

The invention belongs to the technical field of safety valves, and particularly relates to a novel self-detection safety valve. The novel self-detection safety valve comprises a valve body, wherein the bottom end of the valve body communicates with an inlet pipe used for water flow entering of the safety valve, an outlet pipe used for water flow discharging of the safety valve is arranged at one side of the valve body, the top end of the inlet pipe is provided with a sealing cover, and a sealing head is fixed to the bottom of the sealing cover and arranged in the center of the bottom of the sealing cover. According to the novel self-detection safety valve, a pressure sensor is arranged inside a limiting groove, and the pressure sensor is clamped and limited under the cooperation of first extendable rods, limiting springs and clamping blocks so that the pressure sensor can accurately detect the pressure of the pressure springs in real time in a stabler working process; the situation that the pressure springs are loosened in the long-term process, so that the pressure of the pressure springs is not enough, and potential safety hazards occur can be effectively avoided, and the safety of the safety valve in the using process is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a novel self-checking safety valve. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. [0003] At present, the performance of the existing safety valve is too simple. When the safety valve inlet pipe and the sealing cover are closed and opened, the expansion rod and the pressure spring are basical...
