Related Knowledge
Why do we use
pressure seal bonnet?
Pressure sealed
bonnet are often used for valves with high design pressure. The higher the
internal pressure gets, the greater the sealing force beween body and bonnet
become.
For bolted bonnet
valves, the body and bonnet are joined by studs and nuts with a gasket between
the flange faces to facilitate sealing. However,as system pressure
increases,the potential for leakage through the body and bonnet increases.
But for pressure
sealed valve, “bonnet
take-up bolts” to pull the bonnet up and seal against the pressure seal gasket.
That is why when pressure increase, the performance of pressure seal gasket
between body and bonnet becomes better.
