Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a safety valve with an alarm and reminder function. 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. , The safety valve belongs to the automatic valve category, mainly used in boilers, pressure vessels and pipelines, the control pressure does not exceed the specified value, and plays an important role in protecting personal safety and equipment operation. Note that the safety valve must pass a pressure test before it can be used. [0003] In the prior art, the staff or users cannot be reminded during the pressure relief process...
