High temperature and pressure power station gate valve
High temperature and pressure power station gate valve Temperature 450-570 ℃, pressure PN1.6-70.0, nominal diameter 15mm-300mm Material: 1Cr5Mo, 12CrMorV, ZG12CrMoV Widely used in iron and steel, metallurgy, chemical industry and power, energy power plant Other facilities. Technical advantages:
1, the shell is forged and cast two process options, the appearance of smooth, uniform organization, to meet the high temperature and pressure requirements; depending on user needs can provide a full range of forged steel gate valve;
2, matching special materials to ensure that the sealing surface is high Hardness and hardness is poor; precision grinding, smooth as a mirror, wear-resistant corrosion, effectively extending the service life;
3, back seal design, effective protection of packing, to prevent dripping;
4, high pressure water strength, high pressure gas intensity, Such as multi-channel testing, full control of the quality of pressure parts;
5, stem surface precision grinding and hardening treatment, anti-scratch corrosion, effectively reduce the opening and closing torque, easier to operate;
6, design, temperature and pressure, non-corrosive, lubrication, the opening and closing reduce friction, to avoid corrosion of the stem surface, thereby dispense leakage;
7, bi-directional pressure seal design to meet the demanding requirements of the various special conditions;
8 strict hand with research, ensure bilateral sealing surface of the goodness of fit of 90% or more, to achieve bubble-factory seal detection;
. 9, the Z60 series of unique groove design elastic shutter Automatic compensation processing errors, adapt to high temperature conditions to avoid killed; Z62Y series double plate design, the shutter automatic correction processing errors, always maintain the sealing surface 100% goodness of fit, particularly user-friendly site maintenance;
10, since the valve cover Tight seal design, the higher the pressure, the more reliable the seal; Application specification:
