A rotary union steam trap comprises a housing, an inlet, a rotating pipe, a stationary pipe, at least one orifice, a control mechanism and an outlet. The housing comprises a steam compartment that receives steam from the inlet, a steam condensate compartment and a condensate compartment. The rotating pipe fitted to the steam compartment supplies steam to a rotating appliance in need of steam. The stationary pipe opens at one end in the rotating appliance and the other end in the steam condensate compartment and leads steam condensate mixture from the rotating appliance to the steam condensate compartment. The orifice formed between the steam condensate compartment and the condensate compartment leads condensate from the steam condensate compartment to the condensate compartment by a control mechanism fitted in the steam condensate compartment. The outlet with a non return valve leads condensate from the condensate compartment to the environment outside the trap. |
