Brief description of structure
Spring full lift safety valve has the characteristics of simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small return pressure difference, and easy adjustment.
. Nozzle type valve seat. The valve seat is a Valval nozzle type valve seat. When steam flows through the outlet of the valve seat, it reaches the speed of sound and has a large emission coefficient. The sealing surface of the valve seat is overlayed with cobalt-chromium-tungsten carbide, which is wear-resistant. Anti-erosion, long life.
. Thermoelastic valve disc The valve disc is designed as a thermoelastic structure, using its slight deformation under medium pressure to improve the sealing ability and overcome the forward leakage phenomenon of the safety valve when it is close to the set pressure under medium pressure. The valve disc sealing surface adopts advanced laser quenching technology to improve hardness, wear resistance and impact resistance.
Adjusting nut By adjusting the adjusting nut, the spring compression amount is adjusted so that the valve can obtain force easily and quickly.
The back pressure adjustment sleeve is an auxiliary mechanism for adjusting the back pressure of the valve disc. By adjusting the back pressure adjustment sleeve, the appropriate return pressure difference can be obtained. When adjusted upward, the valve back pressure is reduced. When adjusted downward, the valve back pressure increases.
