Working principle of the inverted barrel-type steam trap: 1. The steam trap is installed between the steam heating equipment and the condensate return header. When driving, the bucket is at the bottom with the valve fully open. After entering the steam trap, the condensate flows to the bottom of the tank, filling the valve body and submerging it entirely; thereafter, the condensate is discharged to the return water manifold through the fully open valve. 2. Steam also enters the steam trap from the bottom of the tank, occupying the upper part of the tank and creating buoyancy. The barrel slowly rises, moving the lever gradually toward the valve seat until the valve is completely closed. Air and carbon dioxide gas gather at the top of the drain valve through the exhaust holes in the barrel. The steam discharged from the exhaust vents condenses due to the heat dissipation by the steam trap. 3. When the incoming condensed water begins to fill the tank, the tank starts to exert a pulling force on the lever. As the condensation level continues to rise, the force generated increases until it is sufficient to overcome the pressure difference and open the valve. 4. As the valve begins to open, the pressure difference acting on the valve disc decreases. The barrel body will drop rapidly, causing the valve to open fully. The non-condensable gases accumulated at the top of the steam trap are discharged first, followed by the condensate. As the water flows out of the tank, it carries the dirt with it and out of the drain valve. As the condensate is discharged, steam begins to flow back into the drain valve, and a new cycle starts. I just don’t know if this valve can be used in the gas-water separation section for natural gas. Of course, it’s definitely related to stress as well.
