Title (EN) DRAIN TRAP
(FR) DRAIN À SIPHON
(JA) ドレントラップ
Abstract:
(EN) This drain trap 1 comprises: a reservoir 13; a float 16; a cylinder member 21 which is provided penetrating through a side wall 19 of the reservoir 13, the inside of the cylinder member 21 forming a discharge path 22 of the drain, and the end part at the reservoir 13 side of the cylinder member 21 having formed therein a communication port 23 from which the drain flows into the discharge path 22; a pressure chamber 36; and a discharge valve 31 that is inserted into the cylinder member 21, that has 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 opening and closing the discharge path 22. The size of the communication port 23 and the position thereof in the circumferential direction of the cylinder member 21 are set such that the resultant force of the suction, which the drain generates by the drain flow to the communication port 23, reaches a force that pulls the float 16 downwards.
(FR) Drain à siphon 1 comprenant : un réservoir 13 ; un flotteur 16 ; un élément cylindre 21 qui pénètre à travers une paroi latérale 19 du réservoir 13, l'intérieur de l'élément cylindre 21 formant un chemin d'évacuation 22 du drain, et la partie d'extrémité au niveau du côté réservoir 13 de l'élément cylindre 21 ayant, formé dans celle-ci, un orifice de communication 23 à partir duquel la purge s'écoule dans le chemin d'évacuation 22 ; une chambre de pression 36 ; et un clapet d'évacuation 31 qui est introduit dans l'élément cylindre 21, qui comporte un chemin d'écoulement pilote 35 dans lequel la purge 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, ouvrant et fermant ainsi le chemin d'évacuation 22. La taille de l'orifice de communication 23 et sa position dans la direction circonférentielle de l'élément cylindre 21 sont réglées de telle sorte que la force obtenue de l'aspiration, que la purge génère par l'écoulement de purge vers l'orifice de communication 23, atteint une force qui tire le flotteur 16 vers le bas.
(JA) ドレントラップ1は、貯留室13と、フロート16と、貯留室13の側壁19に貫通して設けられ、内部がドレンの排出路22を構成すると共に貯留室13側の端部にドレンが排出路22に流入する連通口23が形成されたシリンダ部材21と、圧力室36と、シリンダ部材21に挿通され、貯留室13のドレンが圧力室36に流入するパイロット流路35を有し、圧力室36の圧力に応じて進退し排出路22を開閉する排出弁31とを備える。連通口23は、貯留室13のドレンが連通口23へ向かうドレン流れによって生じる吸引力の合力がフロート16を下方へ引っ張る力となるように、シリンダ部材21の周方向における位置および大きさが設定されている。
