The primary function of a steam trap is to hold steam in a heating apparatus or piping system and allow condensate and air to pass. The steam remains trapped until it gives up its latent heat and changes to condensate. 5, record 1, English, - steam%20trap

Appareil de robinetterie autonome qui évacue de manière automatique les condensats se formant dans une enceinte contenant de la vapeur d'eau, tout en restant étanche en présence de vapeur vive ou en établissant si nécessaire un écoulement prédéterminé de vapeur. 7, record 1, French, - purgeur%20automatique%20de%20vapeur%20d%27eau
Record number: 1, Textual support number: 1 CONT
Dans les appareils de chauffage par la vapeur, celle-ci fournit de la chaleur (sa chaleur de vaporisation) en se condensant; ces appareils doivent demeurer pleins de vapeur [...] et l'eau doit en être évacuée; sous réserve de techniques particulières à la vapeur basse pression, cette évacuation est assurée par des purgeurs d'eau condensée, répondant aux mêmes conditions que les précédents [ces purgeurs livrent passage à l'eau, mais s'opposent à la sortie de vapeur]. 4, record 1, French, - purgeur%20automatique%20de%20vapeur%20d%27eau

On rencontre chez certains fabricants les expressions purgeur d'eau, purgeur d'eau condensée, purgeur d'eau de condensation, purgeur de condensats. Toutefois les spécialistes français et québécois n'ont pas jugé opportun de conserver cette synonymie pour le moins gênante. 6, record 1, French, - purgeur%20automatique%20de%20vapeur%20d%27eau

Impulse Trap. Under normal loads the discharge from this trap is intermittent. When the load is heavy, however, the discharge is continuous. This type of trap may be used on any equipment where the pressure at the trap outlet does not exceed 25% of the inlet pressure. 3, record 2, English, - impulse%20trap
Record number: 2, Textual support number: 2 CONT
The impulse steam trap operates on the principle that hot water under pressure tends to flash into vapor when the pressure is reduced. When hot water is flowing to the trap the pressure in the control chamber is reduced, causing the valve to rise from its seal and discharge the water. As steam enters the trap, the pressure in the chamber increases, causing the valve to close, thus reducing the flow of steam to that which can pass through the small center orifice in the valve. 2, record 2, English, - impulse%20trap
