Power station gate valve
Power station gate valve is suitable for cutting off or connecting medium on pipelines of petroleum, chemical and thermal power plants with class 1500 ～ 3500lb and working temperature of - 29 ～ 570 ℃.
1. The gate valve of high temperature and high pressure class power station adopts advanced equal diameter straight through structure, which greatly reduces the flow resistance coefficient and energy loss, and significantly improves the service life and performance of the valve;
2. The middle chamber of the valve adopts pressure self tightening sealing structure with good sealing performance. Both ends of the branch pipe are welded structure;
3. The sealing surface of the gate and valve seat is made of Stellite cobalt base hardfacing, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance;
4. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance;
5. The structure of the hoist can be designed as single plate, double plate and parallel double plate according to the user's requirements;
6. The opening and closing of electric gate valve is controlled by electric device, which is equipped with special motor, reducer, torque control mechanism, field operation mechanism, manual and electric switching mechanism. In addition to local operation, it can also be operated remotely.
