〔産業上の利用分野〕
本発明は水封式電動機の調圧装置におけるその機能保持
の為の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for maintaining the function of a pressure regulating device for a water-sealed electric motor.
従来はダイヤフラムカバーに貫通孔を設けただけであり
、本発明で解決しようとする問題点に対する考慮は特に
されていない。Conventionally, only a through hole was provided in the diaphragm cover, and no particular consideration was given to the problems to be solved by the present invention.
（発明が解決しようとする課題〕
ダイヤフラムカバーに設けた貫通孔を通ってカバーの内
ａｌｌに侵入してきた水垢、異物は排出されにくく、カ
バーの内部に堆積する。(Problems to be Solved by the Invention) Water scale and foreign matter that have entered the inside of the cover through the through holes provided in the diaphragm cover are difficult to be discharged and accumulate inside the cover.
ダイヤフラムは変形することによって電動機内部と外部
の圧力をバランスさせるものである。特に電動機運転中
、内部水は温度上昇によって膨張し、ダイヤフラムは電
動機内部の容積を大きくする方向に変形する。しかし、

果たせなくなる。さらに異物によってダイヤフラムが破
傷することもあり１、その場合、異物等が電動機内部に
侵入し、電動機の特性、寿命を低下せしめる。The diaphragm balances the pressure inside and outside the motor by deforming. In particular, during operation of the electric motor, internal water expands due to temperature rise, and the diaphragm deforms in a direction that increases the volume inside the electric motor. but,
The amount of deformation of the diaphragm is limited by the limescale and foreign matter that have accumulated inside the cover, allowing the original pressure to be adjusted! 1461 You will not be able to fully fulfill your abilities. Furthermore, the diaphragm may be damaged by foreign objects1, in which case the foreign objects may enter the inside of the motor, reducing the characteristics and life of the motor.
本発明はダイヤフラムカバー内部に侵入した水垢、異物
等を堆積させることなく容易に排出させることにある。The object of the present invention is to easily discharge limescale, foreign matter, etc. that have entered the inside of the diaphragm cover without accumulating them.
Ｃ課題を解決するための手段〕
上記目的は、ダイヤフラムカバーに設けた貫通孔の内部
側周囲に、傾斜を持つ座ぐりを施すことによって達成さ
れる。Means for Solving Problem C] The above object is achieved by providing an inclined counterbore around the inside of the through hole provided in the diaphragm cover.
ダイヤフラムカバー内部に侵入した水垢、異物等はカバ
ー内面に堆積しようとする際、カバー内面に施した傾斜
に沿って落下し、貫通孔から外部へ排出される。When limescale, foreign matter, etc. that have entered the inside of the diaphragm cover attempt to accumulate on the inner surface of the cover, they fall along the slope formed on the inner surface of the cover and are discharged to the outside through the through hole.
電動機内部の容積を大きくする方向へダイヤフラムが変
形しはしめる際は、ダイヤフラムとダイヤフラムカバー
の間にある水の排出とともに異物等は傾斜に沿って容易
に排出される。When the diaphragm begins to deform in a direction that increases the internal volume of the electric motor, the water between the diaphragm and the diaphragm cover is discharged, and foreign matter and the like are easily discharged along the slope.
以下、本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.
ダイヤフラム３は、ダイヤフラムカバー４と固定用ボル

貫通孔を中心として、傾斜を持った座ぐり６が施されて
いる。The diaphragm 3 is placed on the frame 2 by a diaphragm cover 4 and fixing bolts 7, and water is sealed inside the motor 1. The diaphragm cover 4 is provided with a through hole 5, and roughly on the inner surface of the diaphragm cover,
A slanted counterbore 6 is provided around the through hole.
貫通孔５を通って、ダイヤフラム３とダイヤフラムカバ
ー４間に侵入してきた水垢、異物等は、ダイヤフラム４
の上面に沈下する際、ダイヤフラムカバー４に設けた座
ぐり５の傾斜に沿って貫通孔５まで移動し、外部に排出
される。Water scale, foreign matter, etc. that have entered between the diaphragm 3 and the diaphragm cover 4 through the through hole 5 are removed from the diaphragm 4.
When it sinks to the upper surface of the diaphragm cover 4, it moves to the through hole 5 along the slope of the counterbore 5 provided in the diaphragm cover 4, and is discharged to the outside.
第２図は貫通孔が複数個の場合の一実施例である。FIG. 2 shows an embodiment in which there are a plurality of through holes.

を損ねることがない。According to the present invention, water scale, foreign matter, etc. are discharged to the outside without accumulating in the diaphragm cover, so deformation of the diaphragm is not obstructed, and therefore, the pressure regulating function of the diaphragm can be sufficiently maintained. Furthermore, damage to the diaphragm caused by foreign objects can be prevented, and the life of the electric motor will not be impaired.
