Control the gas supply pipeline by replacing the electric gate valve or adding a bypass valve at the control valve. As for the problem of water hammer, on the one hand, there is little condensed water in the steam pipeline, and water hammer will hardly happen. On the other hand, even if it is full of water, controlling the opening speed of the gate can weaken or avoid water hammer.
As for the accumulated water in the sub-cylinders, just slightly open the drain valve for a long time. The blowdown pipe and blowdown pipe of our company are block valves, so blowdown valve and blowdown valve have different names according to their different uses. Many boiler plants use stop valves in this area.
