Release Time：2017-10-30
High pressure safety valve is a kind of safety protection valve, its opening and closing parts under the action of external force in a normally closed state. According to the structure, it is divided into vertical hammer type, lever type, spring type and pilot type; according to the valve body structure, it can be divided into closed type and non-closed type. The following are the matters needing attention when installing the high-pressure safety valve: 1. For boilers with rated evaporation greater than 0.5 t/h, at least two safety valves shall be installed; Boilers with rated evaporation less than or equal to 0.5 t/h shall be equipped with at least one safety valve. For boilers with rated steam pressure less than or equal to 3.82MPa, the safety valve throat diameter shall not be less than 25mm; For boilers with rated steam pressure greater than 3.82MPa, safety valve throat diameter. 2. The high-pressure safety valve should be installed vertically in the highest position of the pot dealer and header. Outlet pipes and valves for taking steam shall not be installed between safety valve and drum or header. 3, lever type safety valve to prevent the hammer to move their own device and limit the lever deviant guide frame, spring type safety valve to have a lifting handle and prevent casually twist the adjustment screw device. 4. The cross-sectional area of the connecting pipe between the high-pressure safety valve and the boiler shall not be less than the inlet cross-sectional area of the safety valve. If several safety valves are jointly installed on a short pipe directly connected to the drum, the passage cross-sectional area of the short pipe shall not be 1.25 times of the exhaust area of all safety valves. 5, the safety valve should generally be installed exhaust pipe, exhaust pipe should be straight to a safe place, and have enough cross-sectional area, to ensure the smooth flow of exhaust steam. The bottom of the safety valve exhaust pipe should be put on airs and have a drain pipe connected to a safe place. No valve is allowed to be installed on the exhaust pipe and the drain pipe.
