Introduction of liquid expansion type steam trap: Liquid expansion type steam trap is the most economical experimental trap with energy saving steam trap. Its advantages are: small size, light weight, not afraid of freezing, can automatically discharge air, can be installed anywhere; back pressure rate greater than 80%, stainless steel bellows telescopic volume, good adjustment, the valve is equipped with adjusting bolts, According to the need to adjust the use of temperature, the general subcooling below the saturation temperature of 18 ℃ -40 ℃. Corrugated pipe traps for steam pipe heat, instrument with heat, domestic heating and allows the existence of high temperature condensate heating equipment hydrophobic, using a wide range. Liquid expansion trap features: 1. Stainless steel tube durable, long service life. 2. Adjustable condensate discharge temperature, the use of sensible heat, energy-saving effect is significant. 3. There is always condensate in front of the valve to form a reliable water seal without steam leakage. 4. Unaffected by vibration, steam pressure fluctuations and water hammer effects. 5. Can be installed at any angle, regardless of installation orientation, and the exhaust air performance. 6 simple structure, and with a filter device for easy installation and maintenance. Liquid expansion trap works: The internal structure of the liquid expansion trap is a stainless steel bellows as the main action element, filled with a vaporization temperature below water saturation temperature of the liquid. When the unit is started, the cooling condensate appears in the pipe, the liquid in the bellows is in a condensed state and the valve core is in the open position under the spring force. When the condensate temperature gradually increased, the bellows filled with liquid began to evaporate and expand, the internal pressure increases, the deformation of elongation, moving the valve heart to close the direction of movement, the condensate to saturation temperature before the trap completely closed. Valve always has high temperature condensate, no steam leakage, energy-saving effect.
