THERMOSTATIC STEAM TRAP AND INSERT ASSEMBLY USABLE IN A BODY MEMBER TO FORM A THERMOSTATIC STEAM TRAP

摘要

The thermostatic steam trap assembly disclosed herein comprises a body member (12) and an insert assembly (14), the latter including inlet passage means (62) communicating with the inlet side (28) of the body member, discharge passage means (64) communicating with the discharge side (42) of the body member and diaphragm means (74) carried intermediate the inlet and discharge passage means such that one face thereof cooperates with a valve seat to allow or prevent fluid flow through the passage means. A control chamber (80) is formed adjacent the other face of the diaphragm means (74) and carries a small porous block (82) of material which is saturated with a generally conventional control fluid such that the control fluid is responsive to the temperature of the fluid or the inlet side of the body member to control the position of the diaphragm means.
