Spring Fully Open Closed High Pressure Safety Valve

The spring full-opening closed high-pressure safety valve designed by Dazhong Valve Group is a cooperative brand of YOY Yongyi Valve Group. Cobalt-chromium-tungsten carbide, the valve disc is designed as a thermoelastic structure, and the auxiliary mechanism for adjusting the back pressure of the valve disc can be adjusted by the back pressure adjusting sleeve to obtain a suitable back-seat pressure difference.

• The spring fully open and closed high pressure safety valve has the characteristics of simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small return pressure difference, 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, the speed of sound is reached, and the emission 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, through the adjustment of 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. pressure increases.
