SANITARY STEAM TRAP

摘要

A thermostatic steam trap (10) for use in sanitary environments has a steam trap body (12) consisting of an inlet body portion (16) and an outlet body portion (22). A centering member (28) is disposed generally between the inlet and outlet body portions. A thermostatic bellows/plug assembly (30) mounted to the centering member moves within the steam trap cavity (14), between a first position in engagement with a seat (32) defined by the steam trap body, thereby to resist flow of fluid between the steam trap cavity (14) and the outlet port (24), and a second position spaced from engagement with the seat, thereby to permit flow of fluid between the steam trap cavity and the outlet port. A sanitary seal (36) releasably secures together the inlet and outlet body portions at an interface (46), with the inlet and outlet cavity portions arranged in communication and generally along a vertical axis (A), with the centering member secured therebetween.
