Structure and working principle
The full-open external thread safety valve with handle spring is mainly composed of valve body, valve cover, spring, valve disc, handle and other components. The body and bonnet are threaded together to form a sealed cavity. The spring is installed in the valve cover to produce a certain pre-tightening force on the valve disc. The handle is used to manually operate the safety valve for emergency relief or commissioning if required
Application scenario
This safety valve is suitable for all kinds of industrial pipelines and equipment, especially in the working temperature of air, steam, water, nitrogen and hydrogen mixture and other media equipment or pipelines. It is also suitable for equipment or pipelines with corrosive media as an overpressure protection device
