safety valve
To prevent boilers, pressure vessels and other equipment or pipeline due to excess pressure caused damage to the valves. When was the protection of the body fluid pressure to achieve slightly higher than normal operating pressure of a specified value (that is, open the pressure valve), automatic safety valve to open, emissions of the fluid so that the pressure drop. When the pressure dropped to slightly below normal operating pressure of a certain value (that is, pressure valves back seat), the safety valve automatically shut down and stop emissions fluid and remain sealed.
Class is the role of safety valve to prevent pipes or devices in the medium pressure exceeds the value, to achieve security objectives.
Security is a safety valve by valve, and its hoist pieces of the external force under a permanent state of closure, when the equipment or media pressure in the pipeline increased, exceeding the value of open automatically, through the medium outside the system to prevent emissions Pipe or equipment within the medium pressure exceeds the value. Valves are automatic safety valve, mainly used for boilers, pressure vessels and pipelines, the pressure does not exceed the prescribed control the value of personal safety and protection equipment running play an important role. |
