Safety valve, as the best device for extra-pressure protection, will automatically pen and fully discharge to protect the equipment pressure from going on rise when medium's pressure rises over the allowed value and will automatically close when the pressure lowers to the setting value manufacture and acceptance etc. technical standards. The bonnet of the sealed safety valve is enclosed in order to protect dust and foreign matters from getting in and protect toxic and combustible media from over-flow, while the opened bonnet of the open-type safety valve, which benefits to lower the temperature inside of the spring chamber. is mainly used for the pipeline and container with steam medium and the safety valve with radiator is suitable for the medium with a temperature over 350°C. For the safety valve with a lever, it can be opened manually with the lever when the medium's pressure is up to over 75% of that at which the valve opens. Full-bore safety valve's height of opening 1/4 time the flow diameter with a large amount of discharge, the height of opening for lift safety valve 1/20-1/40 time the flow diameter.
