Description
Technical field
The present invention relates to a kind of safe pressure relief device of adjustable settings pressure value and methods and purposes.
Background technique
Safe pressure relief device is that petrochemical industry, the pressure vessel of chemical plant installations, pipeline or other closed systems prevent superpressure
Important safety.It can be opened under defined temperature and pressure, pressure of releasing, and ensure people's life and national wealth
Safety.Safe pressure relief device does not depend on any extra power usually and acts, so protecting together frequently as the last of bearing device
Protection unit.The wider pressure relief device non-reclosed of domestic application is blasting piece device at present, and rupture disk safe pressure relief device has
The advantages that structure is simple, relieving capacity is strong, but there is also following problems: and (1) explosion precision is low.(2) it is easy to happen fracture by fatigue.
Rupture disk internal stress is higher than the yield limit of material when rupture, and under the action of pulse or pressure, it is broken that fatigue easily occurs for rupture disk
It splits.(3) rupture disk and material directly contact influence vulnerable to medium temperature, corrosivity etc., need to regularly replace.It (4) can not online more
It changes.Replacement rupture disk needs to dismantle pipeline, and the time is long, and risk is high, and inactivity cost is high.
For pressure relief device non-reclosed, other than blasting piece device, ASME boiler and pressure vessel specification and its specification
Case also recommended explosion needle-like relief valve.Relative to rupture disk, explosion needle-like relief valve is high with precision, fatigue effect is small,
