The main features of safety valves are: reliable sealing, leakage loss of medium, pollution of the environment, endangerment of safety, and accelerated damage to the sealing surface.
) Close it in time after taking off to prevent the system pressure from dropping too much and reduce excessive loss of the medium.
) Stable discharge. After the safety valve is opened, it must be stably maintained in the discharge state and have good mechanical characteristics, that is, no frequency jump, chatter, jamming and other undesirable phenomena.
) Timely and accurate opening is the most basic requirement for the performance of the safety valve. When the inlet pressure of the safety valve reaches the predetermined set pressure value, the safety valve disc should open accurately and quickly reach the specified opening height.
Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important role in protecting personal safety and equipment operation.
Safety valves are opening and closing parts that 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, the safety valve prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium outside the system. numerical value.
