Thermal static type bellows steam trap (steam pressure balanced) is the most commonly used advanced energy-saving trap on the current international. Bellows steam trap sensitive work, there are high-temperature condensate valve before the water, no steam leakage, energy saving effect is remarkable.
Its advantages are: automatic row of air volume is small, not afraid of cold, can be installed anywhere; convenient maintenance, can check the repair and replacement parts in the pipeline; the maximum back pressure rate of less than 80%, solid diaphragm, long service life.
Bellows steam trap for blocking the drainage steam to steam mains, steam heat pipe network, instrument tracing and small heating equipment, the use of a very wide scope
The main action element bellows steam trap is a metal membrane box, filled a gasification temperature of the water saturation temperature lower than the liquid. When the device has just started, the pipeline appears low temperature condensate water, and the liquid in the film box is in a condensed state. Valve is in open position. When the condensate water temperature gradually increased, the membrane began to evaporate liquid filled box, the membrane box pressure rise, driven diaphragm valve to close move, in the condensate to saturation temperature before the trap is completely closed, diaphragm with the steam temperature control valve, a waste gas drainage effect. Open valve temperature is lower than the saturation temperature of 15 degrees Celsius and 30 degrees Celsius two kinds of membrane box for choice.
