Drain trap
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 簡単な構造でトラップ内圧力を自動ブロでき るドレントラップを提供する。 【解決手段】 本体1と蓋2とからなるケ―シングで入 口4と弁室3と出口6を形成し、弁室と出口を連通する 弁口16を設け、弁口を開閉してドレンを排出するフロ ―トを弁室内に収容したものにおいて、弁室と出口側を 仕切るダイヤフラム12を弁室下部にストッパ―を兼ね るボルト13で取り付け、ダイヤフラムに弁座部材を取 り付ける。弁室内圧力が使用最高圧力に達するまではダ イヤフラムがコイルバネ18により弁室側に変位して弁 口をフロ―トで開閉される位置に前進させる。弁室内圧 力が使用最高圧力以上になるとダイヤフラムが流体圧力 によりコイルバネに抗してプラグ17側に変位して弁口 をフロ―トで開閉される位置から後退させる。この後退 時にはフロ―トの変位がボルトにより規制され弁口が閉 口されることを防止する。 (57) [Problem] To provide a drain trap having a simple structure and capable of automatically blowing pressure in the trap. SOLUTION: An inlet 4, a valve chamber 3 and an outlet 6 are formed by casing composed of a main body 1 and a lid 2, a valve port 16 communicating the valve chamber and the outlet is provided, and the valve port is opened and closed to drain. When the float to be discharged is housed in the valve chamber, a diaphragm 12 that separates the valve chamber from the outlet side is attached to the lower part of the valve chamber with a bolt 13 also serving as a stopper, and a valve seat member is attached to the diaphragm. Until the pressure in the valve chamber reaches the maximum use pressure, the diaphragm is displaced toward the valve chamber by the coil spring 18 to advance the valve port to a position where it can be opened and closed by a float. When the pressure in the valve chamber exceeds the maximum pressure for use, the diaphragm is displaced toward the plug 17 against the coil spring by the fluid pressure, and the valve port is retracted from the position where it is opened and closed by the float. At the time of retreat, the displacement of the float is regulated by the bolt to prevent the valve opening from being closed.
