Free floating ball steam trap (CS41H)

Free floating ball steam trap (CS41H)working principle

The steam trap is installed between the steam heating equipment and the condensate return pipe. When driving, the bucket is at the bottom and the valve is fully open. After entering the drain valve, the condensed water flows to the bottom of the bucket, fills the valve body, and completely submerges the bucket body. Then, the condensed water is discharged to the return water collection pipe through the fully open valve. Steam also enters the drain valve from the bottom of the barrel, occupying the top of the barrel and generating buoyancy. The barrel slowly rises and gradually moves the lever towards the valve seat until the valve is closed. Air and carbon dioxide gases gather at the top of the drain valve through the exhaust holes in the barrel. The steam discharged from the exhaust hole will condense due to the heat dissipation of the drain valve. When the incoming condensate begins to fill the barrel, the barrel begins to exert a pulling force on the lever. As the condensation water level continues to rise, the force generated increases until the pressure difference can be overcome and the valve can be opened. When the drain valve starts to open, the pressure difference acting on the valve disc will decrease. The barrel will rapidly descend, causing the valve to fully open. The non condensable gas accumulated at the top of the drain valve is first discharged, and then the condensed water is discharged. When the water flows out of the bucket, it drives the pollutants to flow out of the drain valve together. At the same time as the condensate is discharged, steam begins to enter the drain valve again, and a new cycle begins.

Free floating ball steam trap (CS41H)structural form

The steam trap plays a role in blocking steam and draining water in the steam heating system. Choosing a suitable steam trap can achieve the highest working efficiency of the steam heating equipment. To achieve the desired effect, it is necessary to have a comprehensive understanding of the working performance and characteristics of various types of drain valves.

A drain valve must be able to "identify" steam and condensate in order to effectively block steam and drain water. The identification of steam and condensate is based on three principles: density difference, temperature difference, and phase transition. So three types of steam traps were manufactured based on three principles: mechanical, thermo static, and thermo dynamic.
