Detailed Introduction
Bellows Trap
The main acting unit of bellows,which is filled with a ytpe of liquid with gasification temperature lower than water's saturation temperature.When the device just starts,there appears condensate with low temperature in conduits and the liquid in the bellows is in the condensed state.The trap is turned on.When the temperature of condensate water gradually goes up,the liquid in the bellows begins to vaporize and the pressure within it increases.Consequently,the film drives the valve core to move towards the closing direction.Before the condensate water reaches its saturation temperature,the trap is completely shut down.The bellows controls the opening and closing of valves in accordance with steam temperature changes so as to resist steam and discharge water.Available are two alternative bellows with opening temperature 15℃ or 30℃ lower than saturation temperature.
There is high temperature condensate in front of the (steam pressure balance type) when it works, and there is no steam leakage, so the energy saving effect is significant.
Bellows trap,among all existing steam pipes,are presently the ideal substitute of low-pressure (with pressure below PN25)hot motive (disc)traps or bimetallic elements traps (with pressure below PN16).
1.Quick acting speed and zero leakage.
2.Simple structure and convenient maintenance.
3.All components made of alloy-treated stainless steel,resistant to wearing,gas corrosion,long durability.
4.Good emptying capability with quick discharge and easy installation.
5.Capable of combination of multiple bellows,suitable for large discharge.
6.Good air discharge capability,with coldness resistance,zero leakage and backpressure of 75%.
