が生じる。Generally, when transferring liquid in a pump suction line system,
Air gradually enters the pipe system from the joint or the gland, and this air accumulates in a specific part of the suction pipe system, such as a mountainous part, creating an air pocket.
この空気溜りが太き（なると、ポンプの液体を吸入する
力が低下し、ついにはポンプ吸入が不能になるという問
題点がある。When this air pocket becomes thick, the pump's ability to suck in liquid decreases, eventually making it impossible for the pump to suck in the liquid.

示しない船内ポンプへ流れ込むようになって（・る。Below, an explanation will be given of an air venting device for a pump suction pipe system as an embodiment of the present invention with reference to the drawings. This figure shows an air vent device attached to the pump suction pipe system of the lubricating line.The liquid flow (lubricating oil) C from outside the ship ++B is carried out through the lagoon side suction pipe 1.
Connecting rubber suction pipe 2. The water passes through the interior of the in-vessel ocular tube 3 and flows into an in-vessel pump (not shown).

生し易い箇所となる。In general, the connecting rubber suction pipe 2 is installed above the water surface A, taking into account the convenience of inspection and removal, and the inboard pump (not shown) inside the hull B is installed above the water surface, taking into account the pushing water head (4). Since it is arranged below \, the suction pipe system forms a mountain as shown in the figure, and the apex becomes a place where the air inside the pipe P, ff +) is likely to be generated.
この山なり部に空気抜管４が接続されており、空気抜管
４は空気抜弁室５を介して空気チャンバ１６へ連通して
いる。An air vent pipe 4 is connected to this mountainous portion, and the air vent pipe 4 communicates with an air chamber 16 via an air vent valve chamber 5.
空気抜弁室５内には吸入管３内部を流れる流体が侵入し
ており、符号２２は侵入した流体の液面を示している。The fluid flowing inside the suction pipe 3 enters the air vent valve chamber 5, and reference numeral 22 indicates the liquid level of the entered fluid.
そして、空気抜弁室５内には７０−ト６か配設されて、
液面２２上に浮いており、フロート（３上部（こ設けら
れた弁体７が弁座８に係合しうるようになっている。In the air vent valve chamber 5, a 70-toe 6 is disposed,
It floats on the liquid level 22 and has a float (3 upper part) so that the valve body 7 can engage with the valve seat 8.
一方、空気チャンバ１６内部は設定負圧域に自動的に保

の」二部にイ」設されている管＝ｉ ５ａには、起洩液
管１７が接続されており、漏洩した成木は漏洩液管１７
を通して、漏洩液溜１８に流れ込むようになっている。By the way, the air vent valve chamber 5 is designed to prevent liquid leaking from the air vent valve chamber 5 from entering the air chamber 16.
A leaking liquid pipe 17 is connected to the pipe installed in the second part of the pipe = i5a, and the leaking mature tree is connected to the leaking liquid pipe 17.
The leakage liquid flows into the leakage reservoir 18 through the leakage liquid.
」二連の構成により、１吸入管系内に小１、大した空気
は、管内で空気溜りを生しることなく、空気抜管・１を
通して空気抜弁室５に溜まる。'' Due to the dual configuration, small and large air in one suction pipe system passes through the air vent pipe 1 and accumulates in the air vent valve chamber 5 without creating an air pocket inside the pipe.
このようにして、空気抜弁室５に空気か蓄積されると、

バ１６へと流入する。When air is accumulated in the air vent valve chamber 5 in this way,
Since the liquid level 22 is pushed down, 70-)G moves to the lower blade, valves 7 and 8 open as shown in Figure 1, and the air in the air vent valve chamber 5 is maintained at negative pressure. ) flows into the chamber 16.
すると再び７＆而２２は上昇し、それにつれてフロー）
・６も」一方へ移削」するので、弁７，８は再び閉しら

・Since 6 is also "grafted to one side", valves 7 and 8 are closed again.
この繰返しによって、空気抜弁室５に溜まった空気は間
欠的に空気チャンバへ流入する。By repeating this process, the air accumulated in the air vent valve chamber 5 intermittently flows into the air chamber.
このとき、空気チャンバ１６内の負圧は徐々に）成少し

１Ｇ内の空気を偵、出して負Ｊ王を高める。At this time, the negative pressure in the air chamber 16 gradually increases) and approaches the pressure 1[:, or the negative pressure gauge 13 displays the negative pressure, and when the negative pressure decreases to the set value, The pump starting pressure switch 14 starts the air purge pump 11 in response to this. Air vent pump here is air chamber/1
Spy the air within 1G and increase the negative J-King.
空気チャンバ１６内の負圧が設定された値に達すると、
ポンプ停止圧力スイッチ１５が応動して、空気抜ポンプ
１１は停止させられる。When the negative pressure in the air chamber 16 reaches a set value,
The pump stop pressure switch 15 responds and the air vent pump 11 is stopped.
なお、空気チャンバ１６ｉ土、空気抜ポンプ１１の発停
頻度の減少をはかるため、空気抜管４と空気抜管９との
間に介装されるのである。The air chamber 16i is interposed between the air vent pipe 4 and the air vent pipe 9 in order to reduce the frequency of starting and stopping of the air vent pump 11.

After closing the air intake valve 21, open the air intake valve 21, and then open the exhaust valve 20.
By opening it, you get 1 le.

利点がある。As described in detail above, according to the air venting device for a pump suction pipe system of the present invention, an air chamber connected via an air vent valve chamber to a location where an air pocket is generated in the pipe of a liquid pump suction pipe system, With a simple structure that includes a means to automatically maintain the chamber interior within a set negative pressure range, it is possible to prevent air pockets from forming within the suction pipe system, allowing the suction pump to efficiently suck and transfer liquid. There is an effect that can be done,
Further, since air is intermittently discharged by the air bleed valve chamber and the float valve, devices such as the air chamber and the air bleed pump need only have small capacities, which has the advantage of keeping equipment costs low.
