本発明は水道管のコックを急に閉じる時に生ずる衝撃に
よる継手のゆるみを防止する衝撃吸収装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shock absorbing device that prevents a joint from loosening due to the shock that occurs when a water pipe cock is suddenly closed.
水道管はコックを急に閉じるとウォーターノ蔦ンマと呼
ばれる水圧による衝匁が発生しｇｐ！Ｊｉ図に示す様に
水道管１の継手２のねじ部３やゆる／しだね、破裂した
りして水漏れが発生することがある。If you close the tap on a water pipe suddenly, a force called water pressure will occur, causing gp! As shown in Figure Ji, water leakage may occur due to the threaded portion 3 of the joint 2 of the water pipe 1 coming loose, loosening, or bursting.
以上の問題点に鑑み本発明は成されたものである。以下
本発明を実雄例の＃Ｊ２図及び第３図に従い説明すると
衝撃吸収装置ｔ ４は継手部２′を設けると共に、継手

室４ｃ内の空気の体積が縮み衝撃を吸収する。The present invention has been made in view of the above problems. Hereinafter, the present invention will be explained with reference to actual examples shown in FIG. ing. The absorption part 4a has a cylinder shape,
It has a piston 4b inside. The tap water is mixed in the lower part of the piston 4b, and the upper part is the air chamber 4c.The pressure of the tap water increases.The piston 4b rises, and the volume of the air in the air chamber 4c contracts to absorb the impact.

。When the shock absorber ff1t4 with the above configuration is attached to the water pipe 1, even if the water pressure shock is applied to the water pipe 1 due to the closure of the cock, the piston 4b moves upward, so it cannot be attached to the water pipe 1 or a general joint 2. Shock is reduced 0 As mentioned above, an absorbing part that absorbs the impact of the water hammer phenomenon of water pipes is provided in communication with the upper part of the joint part, and the absorbing part is a piston that slides in response to the water pressure of the water pipe. has
This shock absorbing device absorbs shock by compressing the air above the piston, so conventionally, the shock that occurs when a water pipe cock is suddenly closed can cause the joint threads to loosen or the water pipe to burst. However, if an uninvented shock absorbing device is used, the absorbing portion 4a absorbs the shock, which is advantageous because it eliminates loosening of threaded portions and bursting of water pipes.
