structural characteristics
This device is mainly suitable for working conditions with large changes in steam load, which can maintain a certain spray velocity of the cooling water when the flow rate changes, thereby achieving better atomization effect.
a) Stainless steel mobile sleeve (valve disc) surface stacked with hard alloy;
b) Stainless steel fixed sleeve (valve seat) inner wall coating, with spray holes facing the direction of medium flow;
c) Adjustable nozzle equipped with throttling system (first to third stage);
d) The cooling water supply regulation system adopts a straight stroke single seat regulating valve (or V-shaped regulating valve)+throttling device, which not only reduces the leakage of the valve, but also can reasonably distribute the pressure difference on the water supply system. For the same caliber, different flow coefficient CV values can be selected, greatly improving the sensitivity and accuracy of the temperature regulation system.
