As shown in drawings, embodiment of the present utility model provides a kind of hydrophobic control device, the input of hydrophobic control device
End is connected on air inlet pipeline by threeway, the input connection of the outfan and hydrophobic development unit of hydrophobic control device.It is hydrophobic
Control device includes standby steam source steam supply non-return valve 1, prevents reserve steam from flowing back to reserve steam source；Standby steam source supplies user
Steam supply valve 2, when gas equipment needs reserve steam, this valve is opened；Manual isolation valve 3 before automatic steam trap, play resistance vapour row
The effect of water, it is ensured that high-temperature steam will not be entered in hydrophobic control device in a large number；Automatic steam trap 4, in the running of device
In, play a part of hydrops in the hydrophobic control device of timing automatic discharge；Manual isolation valve 5 after automatic steam trap, playing prevents
High-temperature steam discharges the effect of hydrophobic control device；Manual isolation valve 6 before hydrophobic pneumatic operated valve, plays a part of block steam and drain water, really
Protect high-temperature steam to enter in a large number in hydrophobic control device；Hydrophobic pneumatic operated valve 7, when the temperature of reserve steam does not reach setting value
When, hydrophobic pneumatic operated valve 7 is automatically turned on, and is discharged hydrops and is improved steam superheat, when reserve steam temperature meets to be required, hydrophobic gas
Dynamic valve 7 is automatically switched off；Manual isolation valve 8 after hydrophobic pneumatic operated valve, plays a part of to prevent high-temperature steam from discharging hydrophobic control device；
Pressure-measuring device 9, plays a part of to measure steam pressure in air inlet pipeline；Temperature measuring set 10, plays measurement air inlet pipeline and looks for
The effect of that vapor (steam) temperature.On the air inlet pipeline, reserve steam sequentially passes through pressure-measuring device 9, temperature measuring set 10, standby
User's steam supply valve 2 is supplied with vapour source steam supply non-return valve 1, standby steam source, gas equipment is reached；Export in standby steam source steam supply non-return valve
Threeway is installed at end, connects hydrophobic control device, and hydrophobic control device is made up of automatic hydrophobic pipeline and pneumatic hydrophobic pipeline, according to
The pressure and temperature signal of the steam surveyed by pressure-measuring device 9 and temperature measuring set 10 is adjusting stockpiling for hydrops in pipeline
Amount, reaches the purpose for adjusting vapor (steam) temperature.On the automatic hydrophobic pipeline, manual isolation valve 3, automatic hydrophobic before automatic steam trap
