Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.
