Thermostatic traps operate in response to the surrounding steam temperature.
Thermostatic steam trap working principle.
We will also have a brief look at the maintenance procedures of the same.
Thermostatic trap also known as the temperature trap uses expansion of a bimetallic strip an oil filled element or a flexible below to activate a valve.
An essential part of the trap is the small air vent hole in the top of the bucket.
A steam trap is a device used to discharge condensates and non condensable gases with a negligible consumption or loss of live steam steam traps are nothing more than automatic valves they open close or modulate automatically.
This video explains how a thermodynamic steam trap works.
At star up air will enter the steam trap and will be discharged out through the bleed hole.
The three important functions of steam traps are.
In this article we will learn about thermodynamic and vacuum traps.
Tlv traps offer three types of temperature sensing materials to detect differences in temperature.
Inverted bucket steam trap.
Thermoliquid bimetal thermowax.
The operation principle for thermostatic steam traps utilizes the temperature difference between steam and condensate.
As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve.
The inverted bucket steam trap is shown in figure 11 3 3.
Initially the bucket is resting at the bottom of the steam trap and the valve seat is wide open.
In the previous article we discussed the basics of a stream trap and learnt about two types of steam traps mechanical and thermostatic steam traps.
The operation and benefits of 3 different types are considered here liquid expansion traps bimetallic and balanced pressure thermostatic traps.
Bimetallic trap is classified as temperature operated traps thermostatic trap and it s by and large the most robust design amongst the various types of traps in common use.
The expansion of element a leads.
It utilizes bimetallic strips of dissimilar metals stacked together in pairs.
In an oil filled element type steam trap as shown in the figure the element a expands as the temperature of the condensate rises.
These are mechanical type of steam traps working on the principle of buoyancy.
