ある。(Conventional technology) Conventionally, in order to discharge air that accumulates in the middle of water pipes, etc., a small valve or cock is installed in a position where air is likely to accumulate, and when air accumulates, the air is released by manual operation. That's what I was doing. However, with this method, it is necessary to periodically check the state of air accumulation.

うに構成されている。Therefore, in order to save labor in maintenance, an automatic air vent valve as shown in FIG. 2 is used. In this valve, a float 6 is housed in a valve chamber 5, and the valve chamber 5
A valve body 9, which is crimped by a spring 8 to an air discharge lower provided at the top of the valve chamber 5, is connected to a float 6, and when the air in the valve chamber 5 increases and the water level falls, the valve body 9 moves to release the air. is configured to emit.
(解決しようとする問題点)
このような従来の空気抜弁は、構造が複雑であってかつ
大型であるので、手動用のコックなどと比較して設置の
位置が制約され、また高価であるうえに故障し易いとい
う問題があった。(Problem to be solved) Conventional air vent valves have a complicated structure and are large, so compared to manual cocks, installation locations are restricted, and they are expensive and expensive. There was a problem that it was easy to break down.
そこで、本発明は上記のような欠点が改良された小型で
信頼性が高い自動式の空気抜弁を提供することを目的し
とた。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a compact and highly reliable automatic air vent valve that has improved the above-mentioned drawbacks.
(問題点を解決するための手段)
前記の目的を達成するために、本発明では、円錐状また
は椀状の上底の中央に気体逸出通路をまた下底に流体流
入通路をそれぞれ設けた筒状弁室内に、比重が0.95
以下の軟質弾性材料で形成された球状弁体を封入して、
自動式空気抜弁を構成した。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a gas escape passage at the center of the conical or bowl-shaped upper base, and a fluid inflow passage at the lower base. Inside the cylindrical valve chamber, the specific gravity is 0.95.
A spherical valve body made of the following soft elastic material is enclosed,
Constructed with an automatic air vent valve.
(作 用)
このように構成された本発明の空気抜弁を液体配管など
における気体が溜り易い部位の上に、たとえば垂直に取
りつけておくと、配管内の気体および液体は、流体流入
通路を経て筒状弁室内に入る。液体の量が少ない間は気
体が弁室壁と球状弁体との隙間を通って気体逸出通路か
ら放出されるが、液体が弁室内に充満してくると球状弁
体は浮き上がって円錐状の上底に接するようになり、液
体の圧力によって上底に圧接されるから液体が気体逸出
通路から排出されることはない。(Function) When the air vent valve of the present invention configured as described above is installed vertically, for example, above a portion of liquid piping where gas tends to accumulate, the gas and liquid in the piping will flow through the fluid inflow passage. Enter the cylindrical valve chamber. While the amount of liquid is small, gas passes through the gap between the valve chamber wall and the spherical valve body and is released from the gas escape passage, but as the liquid fills the valve chamber, the spherical valve body lifts up and forms a conical shape. Since the liquid comes into contact with the upper bottom of the gas escape passage and is pressed against the upper bottom by the pressure of the liquid, the liquid will not be discharged from the gas escape passage.
また、再び気体が弁室内に蓄積して液面が低下すると球
状弁体に浮力が働かなくなるので、弁室内の圧力と外気
の圧力との差だけでは球状弁体の重さを支え切れなくな
って弁体が液面上に落下し、次いで蓄積した気体が逸出
する。Additionally, if gas accumulates in the valve chamber again and the liquid level drops, buoyancy will no longer work on the spherical valve body, so the difference between the pressure inside the valve chamber and the pressure of the outside air will no longer be able to support the weight of the spherical valve body. The valve body falls onto the liquid surface and the accumulated gas then escapes.
一方、流体圧力が大気圧力よりも低下しようとしたとき
は空気が自由に吸い込まれることになるから、支障を生
じない取り付は場所を選定することが必要である。On the other hand, when the fluid pressure is about to drop below atmospheric pressure, air will be sucked in freely, so it is necessary to select a location for installation that will not cause any trouble.
実施例 本発明の自動式空気抜弁の例を第1図に示す。Example An example of the automatic air vent valve of the present invention is shown in FIG.
図において、lは内部に弁室1aを形成した筒体である
