Spring-loaded full-opening safety valves are characterized by simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small differential pressure back to the seat, and easy adjustment.
Nozzle-type seat: The valve seat is a Laval nozzle-type seat, which reaches the speed of sound when the steam flows through the outlet of the valve seat and has a large discharge coefficient, and the sealing surface of the valve seat is overlay welded with foil-pencil lead casting hard alloy, which is abrasion-resistant and erosion-resistant and has a long service life.
Thermo-elastic valve flap: The valve flap is designed as a thermo-elastic structure, utilizing its tiny deformation under medium pressure to improve sealing ability and overcome the front leakage phenomenon of the safety valve when the medium pressure is close to the setting pressure. The sealing surface of the valve flap adopts advanced quenching technology to improve the hardness, abrasion resistance and impact resistance.
Upper adjusting ring: by adjusting the upper adjusting ring, change the direction of flow of the medium discharged from the valve seat, so that the valve to obtain the appropriate seat pressure.
Lower adjusting ring: through the lower adjusting ring, the valve can quickly reach full open when starting and jumping.6. Back pressure adjusting sleeve: the auxiliary structure for adjusting the back pressure of the valve flap, through the adjustment of the back pressure adjusting sleeve, the valve can get the proper back seating pressure difference.
Simple structure, reliable action, good sealing performance. The structural types for balanced back pressure and unbalanced back pressure can be selected according to user requirements.
Simple structure, reliable action, good sealing performance, especially for high-pressure working conditions.
Simple structure, quick and precise pressure relief, good sealing performance.
