Products Details

Application of Main Steam Gate Valves in Power Plants
The main steam gate valve of a power plant, also known as a special valve for power plants, is suitable for cutting off or connecting media on pipelines in various working conditions such as petroleum, chemical, and thermal power plants, with ANSI CLass 1500-3500 and operating temperatures ranging from -29 to 570 ℃. Applicable media include water, oil, steam, etc. The operating methods include manual, gear transmission, electric, etc.
Structural characteristics of main steam gate valves in power plants
1. The gate valve of the high-temperature and high-pressure power plant adopts an 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 valve chamber adopts a pressure self tightening sealing structure with good sealing performance. The two ends of the branch pipe are welded structures.
3. The sealing surface of the gate and valve seat is made of Stellite cobalt based hard composite welding, which has good wear resistance, high temperature resistance, corrosion resistance, and scratch resistance.
4. The valve stem of the pound level high-temperature and high-pressure power plant gate valve has undergone quenching and surface nitriding treatment, which has good corrosion resistance and scratch resistance.
5. The structure of the opening and closing components can be designed in different forms such as single board, double board, parallel double board, etc. according to user requirements.
6. The opening and closing of electric gate valves are controlled by electric devices, which are equipped with dedicated motors, reducers, torque control mechanisms, on-site operation mechanisms, and manual and electric switching mechanisms. In addition to on-site operation, remote operation can also be carried out.

Gate Valve opens shuts is the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle. The damper plate has two packing surfaces, but the most commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature not Gao Shiwei 2°52'.The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate.The stainless steel gate valve material quality divides into 304 stainless steel gate valves, 316 stainless steel gate valves, 321 stainless steel gate valves.Expressed the method is: Z41H-16P.

The opening and closing part of the hard sealed gate valve is the gate plate, whose motion direction is perpendicular to the fluid direction. The gate valve can only be fully opened and closed without adjustment or throttling.
