High and medium pressure valvesAccording to the technical department of the manufacturer Beigaoke Group, the high and medium pressure butterfly valve cannot discharge condensate water. The high and medium pressure butterfly valve has no response for a long time, and the surface temperature of the valve drops. This is the state where the high and medium pressure butterfly valve cannot be opened.

The cause of this malfunction is:

1. The filter or piping is blocked by impurities or debris, and condensate cannot flow into the high and medium pressure steam butterfly valve. It is necessary to clean the dirt inside the filter, pipeline, and valve.

2. If the amount of condensate discharged by the high and medium pressure butterfly valve is very small or the interval between actions is too long, it is necessary to replace it with a small capacity high and medium pressure butterfly valve.

3. The high and medium pressure butterfly valve that does not discharge condensate is hot and is caused by steam or secondary steam blockage. Once the steam is condensed, the blockage disappears. This is due to the improper installation of high and medium pressure steam butterfly valves, and there should be no place for condensate to be trapped in the inlet pipe midway.

4. The water hammer float is damaged and cannot float due to water ingress. It should be replaced with a new float.

5. Excessive pressure. The pressure of the steam equipment exceeds the maximum working pressure of the high and medium pressure butterfly valve, making it unable to open. Replace the high and medium pressure butterfly valve with a higher working pressure or adjust to reduce the working pressure of the steam equipment.

6. Vacuum in the water heater coil hinders discharge. Install a vacuum breaker between the heat exchanger and water valve.
