Condensate drainage with maintenance interface

Steam trap for draining off condensate from a collecting chamber in which condensate that is generated in a pressure gas system is collected, with the collecting chamber being pressurized with a gas pressure which, depending upon the operating state of the pressure gas system, may be a negative pressure below the atmospheric pressure, an overpressure above the atmospheric pressure or an atmospheric pressure itself, the steam trap comprising:

• a. a level indicator being designed for indicating the level of filling of condensate in the collecting chamber, including when a maximal level of filling in the collecting chamber is reached or exceeded;
• b. an outlet valve which is associated with the collecting chamber and is designed for draining off condensate from the collecting chamber, including against the atmospheric pressure;
• c. an electronic unit which evaluates the signal emitted by the level indicator and activates the outlet valve when the maximal level of filling in the collecting chamber is reached or exceeded;
• and
• d. a housing with a compressed-air connection for the connection with the pressure gas system and an outlet;
• wherein the steam trap is implemented via an interface separable into an integral first assembly unit and an integral maintenance assembly unit which contains at least one of a valve, a spring and a gasket,
• wherein the integral first assembly unit and the integral maintenance assembly unit can be separated at the interface without removing any part of the housing, and wherein any mechanical and electrical connection between the integral first assembly unit and the integral maintenance assembly unit is severed by separation of the units at the interface.
