Tunstall Steam Traps by djsgjg0045


									Steam traps are mechanical devices used to collect steam in industrial equipment.
Most designs place the trap on the bottom of the device, where the steam can be
recovered. Non-condensable gases collect on the top of the trap and steam collects at
its bottom. Tunstall steam traps cover all the basic types.
  Mechanical, temperature, thermodynamic and Venturi versions of this device exist
exist. Each type of trap works in a slightly different fashion, although they all serve
the same purpose.
  Mechanical traps rely on a float to determine when a valve opens and closes. When
the float raises, the trap opens and lets the steam out. When it is closed, it recollects
the condensate.
  A steam trap that relies on temperature open or close depending on whether the
metal heats or contracts. When the metal expands, condensate is collecting and the
valve switches itself to the off position. When the temperature cools, the valve opens
to let out the steam.
  A thermodynamic steam trap relies on pressure differences that allow the machine to
run in regular cycles. The device measures pressure against a valve and opens or
closes depending on the type of pressure.
  Venturi traps are used for applications where the owner or user of the machine wants
as little steam to escape as possible. Steam and condensate flow past forcing the valve
to open or close depending on the pressure felt on the Venturi. The valve opens for a
short time to let out steam before it closes again and the condensate gets recycled in
the system.
  Tunstall steam traps allow factories to conserve energy in certain applications and
reduce the energy costs of operating the machinery necessary for the operation. Most
stam traps are made out of metals with high melting points to prevent the device from
melting. Operators are generally expected to stay away from steam traps while the
device they are attached to is in operation.
