Bimetal Elements Steam Drain Valve
Introduction:
The bimetallic strip steam trap is equipped with adjusting bolts, which can adjust the operating temperature as required. Generally, the adjustment range of undercooling is 15 ℃ – 30 ℃ lower than the saturation temperature, and the back pressure ratio is greater than 70%. It can discharge non condensable gas, is not afraid of freezing, is small in size, is resistant to water hammer and high pressure, and can be installed anywhere. The bimetallic sheet is fatigue and needs to be adjusted frequently.
When the device is just started, low temperature condensate appears 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 rises gradually, the bimetallic temperature sensing element begins to bend and deform, and pushes the valve core to the closed position. Before the condensate reaches the saturation temperature, the drain valve starts to close. The bimetallic sheet controls the valve opening and closing as the steam temperature changes, and prevents steam from draining.
