The spring type pressure stabilizer safety valve comprises a valve body, a pressure inlet and a pressure outlet are formed in the valve body, a valve seat is inserted in the pressure inlet, a flow channel is formed in the valve seat, the interior of the valve body is communicated with the exterior of the valve body through the flow channel, a valve deck is connected to the upper end of the valve body, and a valve clack is arranged in the valve body. A valve rod is connected to the end, away from the valve deck, of the valve clack, penetrates through the valve body and extends out of the valve body, a pressure adjusting spring is arranged in an inner cavity of the valve deck and drives the valve rod to slide towards the valve seat, a driving piece is arranged on the valve body and drives the valve rod to slide away from the valve seat, and a plurality of check blocks are arranged in the circumferential direction of the valve body. The pressure stabilizer safety valve has the effect of reducing the damage probability of the pressure stabilizer safety valve.
Description
technical field [0001] The present application relates to the field of valves, in particular to a safety valve for a spring-type pressure regulator. Background technique [0002] The regulator safety valve is a very critical overpressure protection device for the reactor coolant system of nuclear power plants (nuclear power plants, nuclear submarines, etc.), and it is also the last overpressure protection barrier for the reactor coolant system; when the safety valve is installed on the regulator , To adjust the opening pressure (set pressure) to a very precise value, the deviation is only ±1%. The normal operating pressure of the reactor coolant system is lower than the opening pressure of the pressurizer safety valve. When abnormal operation of the system causes the pressure of the reactor coolant to rise and reach the opening pressure of the safety valve, the safety valve must be opened immediately to complete the pressure relief function. When the system is depressurize...
