What to pay attention to when installing the valve
Answer: 1. The high temperature valve above 200 °C is at normal temperature due to the device. After normal use, the temperature increases, the bolt is heated and the gap is enlarged. Therefore, it is necessary to tighten it again, which is called “heat tightâ€. The operator should pay attention to it. This operation is otherwise prone to leakage.
2. When the climate is cold, the water valve should be closed for a long time, and the water after the valve should be removed. After the steam valve stops steaming, the condensate should also be removed. The bottom of the valve is like a wire plug that can be turned over to drain.
3, non-metallic valves, some are hard and brittle, and some have low strength. When operating, the opening and closing force should not be too large, especially not to make it strong. Also pay attention to avoiding object bumps.
4. When the new valve is used, the packing should not be pressed too tightly, so as not to leak, to avoid the valve stem being pressed too much, accelerating wear, and it is difficult to open and close.
