Product Introduction
Bellows seal trap
The thermo-sensitive element of bellows seal traps is bellows filled with volatile liquid,which employs the volatility of the liquid and flexibility of the bellows.When temperature of the steam pipe goes up,the liquid volatilizes into gas,the size expands and produces pressure to impel bellows to stretch.In contrast,when temperature of the steam pipe goes down to the temperature for gas to turn into liquid,the size gets smaller and the bellows contract due to lack of impetus.
Merits
1.Convenient use due to adjustable water discharge temperature ranging from 70 to 100 degrees.
2.Capability to prevent discharge of high-temperature condensate so as to maintain heat energy of the steam pipe.
3.Continuous water discharge without noise.
4.Free from the effect of small fluctuation of steam pressure.
5.Simple structure,small size and easy installation.
6.Improvement of discharge capacity condensate by increasing diameter of bellows.
7.Good air diameter performance with resistance to coldness.
8.Zero leakage and backpressure ratio up to 75%.
Installation/attention for use
Before the installment of pipeline,use the steam to blow off the pollutant.The arrow shows the direction consistent with the flow direction.
Ahead of the trap,the thermal tube of 1～2 meters need no heat-preservation.Be installed at thermal position lower than the condensation water discharge point of the steam-using equipment.
Before leaving the plant,the hydrophobic temperature of trap has been adjust around 95℃.If it is needed to change the hydrophobic temperature or the displacement,open the shielding bonnet,loosen the lock nut,revolve the adjusting screw revolve the valve core clockwise,the hydrophobic volume reduces and the hydrophobic temperature drops;revolve it counterclockwise,the valve core backlashes,the hydrophobic volume increases,and the hydrophobic temperature rises.After the adjustment ended,tighten the lock nut.
It is needed to make the periodic maintenance and clear the pollutant before the filtration screen,so as to guarantee the trap work normally.
