Brief introduction of imported bimetallic trap:
German rock "de lock" bimetallic trap is a kind of solid structure steam trap. Its advantages are: not afraid of water hammer, high pressure resistance, small size, light weight, not afraid of freezing, can automatically exhaust air, can be installed at any position; back pressure rate is greater than 80%.
Bimetallic trap is driven by bimetal temperature sensing element to open and close the valve core. When the device is just started, there is low-temperature condensate in the pipeline, the bimetallic sheet is flat, and the valve core is in the open position under the spring force. When the temperature of condensate water increases gradually, the bimetal temperature sensor begins to bend and deform, and push the valve core to the closed position. Before the condensate reaches the saturation temperature, the drain valve is completely closed. There is always high temperature condensate in front of the valve, no steam leakage and good energy saving effect.
Working principle of imported bimetallic trap:
The main component of bimetal trap is bimetal temperature sensing element, which deforms with the rise and fall of steam temperature and pushes the valve core to open and close the valve. The bimetallic steam trap is equipped with adjusting bolts, which can adjust the operating temperature according to the needs. Generally, the adjustment range of undercooling is 15 ℃ - 30 ℃ lower than the saturation temperature, and the back pressure rate is greater than 70%. It can discharge non condensable gas, is not afraid of freezing, has small volume, can resist water hammer and high pressure, and can be installed at any position. Bimetallic sheet is fatiguing and needs to be adjusted frequently. When the device is just started, there is low-temperature condensate in the pipeline, the bimetallic sheet is flat, and the valve core is in the open position under the spring force. When the temperature of the double core rises, the temperature of the metal plate begins to bend. Before the condensate reaches the saturation temperature, the trap starts to close. The bimetallic sheet controls the valve switch with the change of steam temperature to stop steam and drain water. Working principle of bimetallic trap.
