バケツトフロート形スチームトラップに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam trap using a downward-opening bucket float, and in particular to a bucket whose upper part is made of a spherical shell and whose outer surface is used as a sealing part to open and close the valve opening by contacting the valve seat. The float is accommodated in a free state in the valve chamber, and the spherical seal portion on the outer surface of the upper part is brought into direct contact with a valve seat arranged to protrude from the upper side of the valve chamber to open and close the valve port. Regarding the bucket float type steam trap.
従来のバケツトフロート形スチームトラップのバケツト
フロートはレバーやリンク等のメカニカルな手段で弁ケ
ーシングに連結されているので、機械的に案内されて変
位する。The bucket float of a conventional bucket float type steam trap is connected to the valve casing by a mechanical means such as a lever or a link, so that it is mechanically guided and displaced.
しかし、本発明に係わるトラップは弁室内に自由状態で
収容したバケツトフロートがその内部に導入される蒸気
量の多少、即ち浮力の大小により浮上降下し、弁口を開
閉する。However, in the trap according to the present invention, a bucket float freely accommodated in a valve chamber floats up and down depending on the amount of steam introduced into the trap, that is, the magnitude of buoyancy, and opens and closes the valve port.
従つて、バケツトフロートが降下位置に於いて横方向に

し、上端がバケツトフロートの下部開口を通して内部に

を半球面状に形成したものてある。Therefore, if the bucket float is deviated laterally in the lowered position, it will catch on the valve chamber wall during the floating process, making it impossible to close the valve port. Also, if it is tilted in the lowered position, it will also be tilted when the valve port is closed.
This condition is not only unstable, but also causes internal steam to overflow, and the resulting vibrations cause the bucket float to separate from the valve seat, causing steam to leak. The present invention aims to eliminate such inconveniences by arranging a valve seat with an open valve port so as to protrude to the upper side of the valve chamber, and making the upper part a ball shell so that its outer surface is in contact with the valve seat. A downward-opening bucket float with a sealing part that opens and closes the valve opening is housed in the valve chamber in a free state, and an introduction pipe is erected at the bottom of the valve chamber so that the upper end enters the interior through the lower opening of the bucket float. The upper end of the introduction tube is formed into a hemispherical shape.
作用は次ぎの通りである。The action is as follows.
バケツトフロートは弁座から離れて降下する時に、横方

する。When the bucket float descends away from the valve seat, even if it deviates laterally or tilts, the inner spherical surface of the upper spherical shell hits the hemispherical surface of the upper end of the inlet tube, and it does not slide. - Then, the center of the bucket float, that is, the inner apex of the bulb shell, is displaced to a position where it rests on the upper end of the introduction pipe, and it stops with the lower opening positioned in the horizontal direction. Therefore, since the bucket float floats up again from this state, the bucket float does not get caught on the inner wall of the valve chamber or obstruct the valve port in the tilted state. Next, the illustrated embodiment will be described in detail.

The lid member 4 is attached to the bolt 5 via the gasket 3 for airtightness.
It is attached with. The inlet 2 communicates with the valve chamber 7 through an inlet pipe 6. A downward bucket float 8 is arranged in a free state around the introduction pipe 6. The bucket float 8 has a bell shape with a cylindrical periphery of a hemispherical shell. The valve chamber 7 communicates with an outlet 11 through a valve port 10 formed by a valve seat member 9 . 12 is an O-ring gasket for airtight maintenance, 13 is a plug for attaching the valve seat member 9 to a predetermined position, and 14 is a gasket.
