Importance of safety valve dynamic stability

Range Top Burner Valve for when a sudden rise in the protected system operating pressure, resulting in an additional force elements acting on feelings, so that the element moves to open a gap in the valve passage, the medium is discharged through the gap, pressure drops.
Dynamic stability safety valve directly affects the safety valve discharge capacity and service life of components, discharge channel cross-sectional area and the discharge capacity of the Stove Top Burner Valve of the shock would reduce the safety valve, and the valve seat and the same opening height limit collision bits will damage the valve sealing surfaces and other parts, two acting safety valve most likely to produce valve shocks.
Safety valve dynamic instability is mainly due to the following reasons: safety valve discharge capacity is more than a Gas Valve For Water Heater into the media flow, spring just had big, big back pressure valve and the outside world in the chamber when the valve is opened Dynamic interference.
