Spring-type safety valve is to rely on the strength of the spring will be pressed on the valve seat in the valve seat, so that the safety valve is closed, the spool below the top of the force by the steam up. Normal operation, the spring down the clamping force is greater than the upward thrust of the steam, the valve is turned off. When the steam pressure from the safety valve seat pressure, the steam force on the spool is greater than the spring force, so that the spool from the top, the safety valve exhaust. Through the valve stem upper part of the adjustment screw to change the spring tightness, you can adjust the safety valve from the seat pressure. This kind of safety valve has the advantages of convenient adjustment, small volume and weight, large exhaust steam capacity and so on. It is suitable for different parameters and different capacity boilers.
