The role of Italian Besa safety valves in the chemical industry

Italian BESA safety valve used in pressure equipment 、On containers or pipelines ，As an overpressure protection device .When the device 、Container orPressure inside the pipeline When the force increases beyond the allowable value ，Valve automatically opens ，Subsequently, total emissions ，To prevent equipment 、Pressure relay inside containers or pipelines Continuously increase； When the pressure drops to the specified value ，The valve should automatically and promptly close ，fromAnd protect the equipment 、Safety of containers or pipelines run.

The safety valve can be directly driven by the system pressure at the valve inlet ，In this case, the mechanism is provided by a spring or heavy hammer Load to overcome the medium pressure acting under the valve disc .They can also be piloted and driven by a mechanism ，The institution explained through Apply a closing force to open or close the safety valve .Therefore ，According to the above driving mode, the safety valve is divided into direct operation Usage and pilot type.

The safety valve can be opened proportionally throughout the entire range of opening heights or within a considerable range of opening heights ，It can also be done in a micro Proportional opening within a small opening height range ，Then suddenly open to the fully open position .Therefore ，Safety valves can be divided into proportional types And fully open type.

safety valve .An automatic valve .It does not rely on any external force ，But instead, it uses the force of the medium itself to discharge a rated number Quantity of fluid ，To prevent the pressure inside the system from exceeding the predetermined safe value； After the pressure returns to normal ，Close the valve again and prevent it The medium continues to flow out.
