FAHF Breathing Valve product details

FAHF Breathing Valve product overview
Baigang group's production and sales of steel valves FAHF Breathing Valve selection is determined by the operating pressure of the relief valve nominal pressure, is determined by the operating temperature of the relief valve using temperature range, up to calculate the relief valve set pressure value of the spring or leverage constant pressure range, then determined according to the working medium of the relief valve material and structure, according to the throat area of relief valve discharge volume to calculate the relief valve.

How FAHF Breathing Valve works
Breathing valves play a safety role in the system. When the system pressure exceeds the specified value, the breath valve Ting open, the system part of the gas into the atmosphere, the system pressure does not exceed the allowable value, so as to ensure that the system is not over pressure and accidents. Safety valve, also known as relief valve. The figure shows several typical safety valve structure. Figure a piston-type safety valve, spool is a flat. When the pressure exceeds the safety value determined by the spring force, the piston A is pushed open and a part of the compressed air is discharged into the atmosphere from the valve port. When the pressure of the air source is lower than the safety value, the spring is driven Pistons down, close the valve port. 

For the pilot-style breathing valve, a small direct acting valve to provide control of the pressure acting on the diaphragm, the diaphragm is the core of the hard core, pressure on the valve seat. When the air pressure A greater than the safety pressure, the spool open, compressed air from the left output hole into the atmosphere. Diaphragm-type safety valve and pilot-operated safety valve pressure characteristics better, sensitive action; but the maximum opening force is relatively small, that is, poor flow characteristics. Practical application, should be based on the actual need to choose the type of safety valve, and according to the maximum displacement of its choice of path.    

Fire breathing valve in the system from the safety protection. When the system pressure exceeds the specified value, the safety valve Ting open, the system part of the gas into the atmosphere, the system pressure does not exceed the allowable value, so as to ensure that the system is not over pressure and accidents. Safety valve, also known as relief valve. The figure shows several typical safety valve structure. Figure a piston-type safety valve, spool is a flat. When the pressure exceeds the safety value determined by the spring force, the piston A is pushed open and a part of the compressed air is discharged into the atmosphere from the valve port. When the pressure of the air source is lower than the safety value, the spring is driven Pistons down, close the valve port.
