The pressure wave buffer flow path formed in the cylindrical portion communicates with the flow path formed in each pipe joint.
〈作用〉
上記構成により本発明のウォータハンマ防止器は、
■円筒部がゴム状弾性体て形成されたことにより、圧力
波緩衝流路かウォータハンマによって生じた圧力波を緩
衝する。<Function> With the above configuration, the water hammer preventer of the present invention has the following features: (1) Since the cylindrical portion is formed of a rubber-like elastic body, the pressure wave buffer passage buffers pressure waves generated by the water hammer.

常に流体か流れる状態になっている。■By providing a pressure wave buffer flow path in the piping flow path, fluid does not stagnate inside the water hammer preventer.
It is always in a state of fluid flow.
〈実施例〉 本発明の実施例を図により説明する。<Example> Embodiments of the present invention will be described with reference to the drawings.
第１図に示すウォータハンマ防止器１は、圧力波緩衝体
２とケーシング３と管継手４と管継手５とから成る。The water hammer preventer 1 shown in FIG. 1 consists of a pressure wave buffer 2, a casing 3, a pipe joint 4, and a pipe joint 5.

れている。The pressure wave buffer 2 includes a cylindrical portion 6 and a buffer chamber 7 formed around the cylindrical portion 6. The cylindrical portion 6 is made of a rubber-like elastic body, and has a pressure wave buffer passage 8 formed therein. The buffer chamber 7 is
It is formed along the outer peripheral surface 6a of the cylindrical portion 6. The inside of the buffer chamber 7 is maintained at a predetermined pressure. Further, a casing locking portion 6b is formed at the end of the cylindrical portion 6.
前記ケーシング３は、前記圧力波緩衝体２か内挿されて
いる。そして、ケーシング３に設けられた環状突片９に
前記ケーシング係止部６ｂか係止されている。The pressure wave damper 2 is inserted into the casing 3 . The casing locking portion 6b is also locked to an annular protrusion 9 provided on the casing 3.
前記管継手４は、前記ケーシング３に設けられた管継手
接続部１０に接続される。管継手４と円筒部６との間に
はワッシャ１１か設けられている。The pipe joint 4 is connected to a pipe joint connection portion 10 provided in the casing 3. A washer 11 is provided between the pipe joint 4 and the cylindrical portion 6.
ワッシャ１１は管継手４と円筒部６との密着性を良好な
ものにしている。そして、管継手４に形成された流路１
４と前記圧力波緩衝流路８とか円滑に連通されている。The washer 11 provides good adhesion between the pipe joint 4 and the cylindrical portion 6. Then, the flow path 1 formed in the pipe joint 4
4 and the pressure wave buffer channel 8 are smoothly communicated with each other.

老継手５に形成された流路１５とを円滑に連通させる。Further, the pipe joint 5 is connected to a pipe joint connection portion 12 provided in the casing 3. A cylindrical core 1 is provided in the cylindrical portion 6.
3 is inserted, and the tsuba 1 provided on the outer periphery of the core 13
A flange receiver formed on the pipe joint 5 is fitted into the portion 5a. The core 13 allows the pressure wave buffer passage 8 and the passage 15 formed in the old joint 5 to communicate smoothly.

衝流路８が狭くなるという不都合が生しる。Next, when the water hammer preventer 1 is applied to a pipe where high-pressure pressure waves occur or a pipe through which high-pressure fluid flows, it becomes necessary to increase the air pressure in the buffer chamber 7. However, when the atmospheric pressure is increased, the buffer chamber 7 expands by one level, causing problems such as the pressure wave buffer 2 becoming unable to be inserted into the casing 3 and the pressure wave buffer passage 8 becoming narrower.
そこで、第２図に示す様に、圧力波緩衝体２の緩衝室７
