Spring Full Lift Safety Valve With Wrench
The full-lift safety valve with wrench spring designed by Dazhong Valve Group is a cooperative brand of YOY Yongyi Valve Group's safety valve. The full-lift safety valve with wrench spring has simple structure and good sealing performance. Nozzle-type valve seat, the seat sealing surface is surfacing with cobalt-chromium-tungsten carbide, thermoelastic valve disc: the valve disc is designed as a thermoelastic structure, and the valve disc sealing surface adopts advanced laser quenching technology. By adjusting the adjusting nut, the spring compression is adjusted. The valve can easily and quickly obtain the accurate set pressure.
The spring full-lift safety valve with wrench has the characteristics of simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small pressure difference on the return seat, and convenient adjustment.
Nozzle-type valve seat: The valve seat is a valve seat of the valve seat type. When the steam flows through the outlet of the valve seat, it reaches the speed of sound, and the discharge coefficient is large. Wear and erosion resistance, long life.
Thermo-elastic valve disc: The valve disc is designed as a thermo-elastic structure, which uses 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 The sealing surface adopts advanced laser quenching technology, which improves the hardness, wear resistance and impact resistance.
Adjusting nut: By adjusting the adjusting nut, the spring compression can be adjusted, so that the valve can easily and quickly obtain an accurate set pressure.
Back pressure adjustment sleeve: an auxiliary mechanism for adjusting the back pressure of the valve disc. By adjusting the back pressure adjustment sleeve, a suitable return pressure difference can be obtained. When the back pressure is raised, the back pressure of the valve is reduced. When it is lowered, the valve back pressure increases.
