Abstract
(EN)
This drain pipe 1 comprises: a reservoir 13; a discharge path 22 that communicates with the reservoir 13; an annular valve seat 25 provided protruding into the discharge path 22; a pressure chamber 36; a valve body 34 that has formed therein a pilot flow path 35 through which the drain of the reservoir 13 flows into the pressure chamber 36, and that advances and retreats in accordance with the pressure in the pressure chamber 36, thereby seating and unseating the valve body to and from the valve seat 25 from the upstream side thereof so as to open and close the discharge path 22; and a float 16 that is provided in the reservoir chamber 13, and that opens and closes an opening in the pilot flow path 35 in the valve body 34. The valve seat 25 has a seat surface 25a on the upstream side of a protruding end surface 25b. The valve body 34 has: a tapered part 34b that makes surface contact with the seat surface 25a; and a cylindrical part 34c which is formed on the downstream side of the tapered part 34b, and of which the opening surface area formed between the cylindrical part 34c and the protruding end surface 25b is smaller than the opening surface area formed between the seat surface 25a and the tapered part 34b when the valve body 34 is unseated.

L'invention concerne un tuyau de drainage (1) comprenant : un réservoir (13) ; un trajet d'évacuation (22) qui communique avec le réservoir (13) ; un siège annulaire de soupape (25) qui fait saillie dans le trajet d'évacuation (22) ; une chambre de pression (36) ; un corps de soupape (34) dans lequel est formé un trajet d'écoulement pilote (35) à travers lequel le drain du réservoir (13) s'écoule dans la chambre de pression (36), et qui avance et recule en fonction de la pression dans la chambre de pression (36), ce qui permet d'appuyer et de retirer le corps de soupape sur et depuis le siège de soupape (25) depuis le côté amont de ce dernier de façon à ouvrir et à fermer le trajet d'évacuation (22) ; et un flotteur (16) qui est placé dans la chambre du réservoir (13) et qui ouvre et ferme une ouverture dans le trajet d'écoulement pilote (35) dans le corps de soupape (34). Le siège de soupape (25) a une surface de siège (25a) sur le côté amont d'une surface (25b) d'extrémité saillante. Le corps (34) de soupape comprend : une partie (34b) conique qui établit un contact de surface avec la surface (25a) de siège ; et une partie (34c) cylindrique qui est formée sur le côté aval de la partie (34b) conique, et dont la surface d'ouverture formée entre la partie (34c) cylindrique et la surface (25b) d'extrémité saillante est plus petite que la surface d'ouverture formée entre la surface (25a) de siège et la partie (34b) conique lorsque le corps (34) de soupape n'est pas en appui.
