DEVICE FOR DISCHARGING CONDENSATE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: outlet opening 3 receives connecting pipe 4 with seat 5 whereon valving member 6 is mounted. The valving member is made of a flexible material and is a plate whose one end is secured to connecting pipe 4 and the other one is provided with float 8. Bearing surface 9 on float 8 are opposite to the edge of the opening in seat 5. When condensate enters housing 1 float 8 lifts, bends flexible valving member 6, and opens outlet opening 3. On lowering the level of condensate valving member 6 sets down on seat 5 under the action of the weight of float 8. A positive pressure provides pressing flexible valving member 6 to seat 5. The mass of float 8 provides such a level of condensate that seat 5 is still submerged into condensate thus preventing leakage of steam through the connecting pipe. EFFECT: enhanced reliability. 1 dwg
