Technical field
This utility model relates to valve technology field, particularly relates to a kind of high temperature high voltage resistant relief valve.
Background technology
Relief valve is a kind of special equipment for pressure system overpressure protection, is a kind of automatic valve.Work as system pressure
When reaching set-pressure, it is not by any external force, but utilize the power of medium itself to discharge the fluid of certain load quantity,
In case pressure exceedes predetermined safety value in locking system.When pressure recovers normal, valve will go closedown again to prevent medium from continuing
Afterflow goes out.High-temperature high-pressure fuel gas relief valve is in squash type servosystem energy fuel gas pipeline the one of gaseous-pressure overload protection
Plant the safety device of pressure limiting, specifically, it is simply that when the High Temperature High Pressure that gas generator produces in the squash type servosystem energy
When combustion gas exceedes the setting pressure required for system, high-temperature high-pressure fuel gas relief valve will automatically turn on, by relief valve nozzle
Unnecessary combustion gas is discharged system, and when gaseous-pressure is less than the safe pressure of default, High Temperature High Pressure relief valve will be automatic
Close and relief valve nozzle is thoroughly obturaged so that the combustion gas in system will not leak.Thus in playing i.e. protection system remaining
Workpiece did not lost efficacy because gaseous-pressure is too high, the most not have impact on the functional of whole system because of the sealing problem of valve
Energy.
In existing High Temperature High Pressure relief valve, cooling-down effect is bad, and high temperature or high pressure can cause the parts such as spring valve rod to become
Property, the uncontrollable problem causing error starting occur or not starting of spring, and High Temperature High Pressure make common flap seal
Property be deteriorated.
