Hydrophobic valve product type and working principle introduction

The hydrophobic valve is a valve used in steam pipe networks and equipment to automatically discharge condensed water, air and other non-condensable gases, and block water vapor leakage.
        The hydrophobic valve is a valve used in steam pipe networks and equipment to automatically discharge condensed water, air and other non-condensable gases, and block water vapor leakage.
        Hydrophobic valve type:
        Depending on the working principle of the steam trap, the steam trap can be turned into the following three types:
        1: Mechanical type: relying on the change of the height of the condensate in the steam trap
        (1) Float type: the float is a closed hollow sphere
        (2) Open-up float type: the float is an open-up bucket type
        (3) Open down float type: the float is a bucket type with an open downward
        2: Thermostatic type: action based on changes in liquid temperature
        (1) Bimetal: sensitive original is bimetal
        (2) Steam pressure type: the sensitive original is a bellows or ink cartridge, and the inside is filled with volatile liquid.
        3: Thermodynamic type: It acts by changing the thermodynamic properties of the liquid.
        (1) Disc type: Since the flow rate of liquid and gas is different under the same pressure, different dynamic and static pressures are generated to drive the disc valve action.
        (2) Pulse type: Since the condensed water of different temperatures passes through the two-pole series orifice plate type, the different pressures between the two-pole orifice plate shape act to drive the valve flap to move.
        The working principle of the hydrophobic valve:
        1. The steam trap is installed between the steam heating device and the condensate return header. When driving, the bucket is at the bottom and the valve is fully open. After the condensate enters the trap, it flows to the bottom of the bucket, fills the valve body, and is completely immersed in the barrel. Then, the condensed water is discharged to the return header through the fully open valve.
        2. The steam also enters the trap from the bottom of the barrel, occupying the top of the barrel and generating buoyancy. The barrel slowly rises and gradually moves the lever in the direction of the seat until the valve is completely closed. Air and carbon dioxide gas collect through the exhaust orifice of the barrel and collect at the top of the trap. The steam discharged from the vent hole will condense due to the heat dissipation of the trap.
        3. When the incoming condensate begins to fill the barrel, the barrel begins to exert a pulling force on the lever. As the condensate level continues to rise, the resulting force continues to increase until the pressure differential can be overcome and the valve is opened.
        4. The valve begins to open and the differential pressure acting on the flap will decrease. The barrel will drop rapidly and the valve will be fully open. The non-condensable gas accumulated on the top of the trap is discharged first, and then the condensed water is discharged. When the water flows out of the barrel, it drives the dirt out of the trap together. At the same time as the condensate discharges, the steam restarts into the trap and a new cycle begins.
