      Z961Y-P54100V, Z961Y-P54140V, Z961Y-P54170V high-temperature and high-pressure electric power station gate valves: electric, butt welding connection, open-rod wedge rigid single gate, valve seat sealing surface material for Cr-Mo-V steel surfacing welding Co-Cr-W alloy, working pressure 10MPa ~ 17MPa, valve body material for chromium-Mo-V steel high-temperature and high-pressure power station gate valves.


      1. Design and manufacture according to JB/T3595 and other standards, and can be used in conjunction with domestic equipment.


      2, the valve middle chamber adopts the pressure self tightening type sealing structure, good sealing performance, and the two ends of the branch pipe are welded structures.


      3. The sealing surface of gate and valve seat is made of Stellite cobalt-based cemented carbide surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance.


      4. The valve stem is quenched and tempered and nitriding on surface. It has good corrosion resistance and scratch resistance.


      5, the structure of the opening and closing parts can be designed as single board, double board and parallel double board according to user's requirements.


      Reference standards for gate valves of high temperature and high voltage electric power stations


      Manufacturing and acceptance technical conditions are stipulated in the standard E101 and JB/T3595-93 for Japanese thermal power valves.


      The length of the structure shall be provided according to E101 or provided by the user.


      The welding groove is connected with the electric power industrial management standard 78DG or provided by the user.
