First, the power station main steam valve product use
Power
station main steam gate valve, also known as power station special
valves, pounds of high temperature and pressure power station gate valve
for ANSI CLass1500-3500, operating temperature -29 ~ 570 ℃ in the oil,
chemical, thermal power stations and other conditions of the pipeline,
cut off or Through the media. Applicable medium: water, oil, steam and
so on. Mode of operation are: manual, gear transmission, electric and so
on.
Second, the power plant main steam valve product structure characteristics
1,
high temperature and pressure pounds of power plant gate valve using
advanced runner path straight through structure, greatly reducing the
flow resistance coefficient and energy loss, significantly improve the
valve life and performance.
2, the valve cavity self-tight pressure seal structure, good sealing performance. Branch ends of the welded structure.
3, the gate and valve seat sealing surface using Stellite (cobalt
stellite) hardcore welding, wear, high temperature, corrosion
resistance, good scratch resistance.
4, pounds of high-temperature high-pressure gate valve stem by
quenching and nitriding surface treatment, has good corrosion resistance
and abrasion resistance.
5, the structure of the opening and closing parts can be designed
according to user requirements into single board, double board, parallel
double board and other forms.
6, the electric gate valve to open and close by the electric device to
control the electric devices were equipped with a dedicated motor,
reducer, torque control agencies, on-site operating agencies, manual,
electric switching agencies. In addition to local operations, but also
for long-distance operation.
