Description

本発明は、灯油ポンプやその他のサイホン式液体移動装置に関する。The present invention relates to a kerosene pump and other siphon type liquid moving devices.

液体をタンクから別のタンクに移し変える際に、構造が簡単なサイホン式ポンプがよく用いられているが、これらは液体を動力源なしで移動させるだけのものである。Siphon pumps with a simple structure are often used when transferring liquid from one tank to another, but these only move the liquid without a power source.

ポンプ稼動後、移動する液体は両タンクの液面がほぼ同じ高さになるまで流出し続ける。そのまま放置した場合は液体が溢れ出し、周囲を汚損しまた内容物によっては非常に危険である。After pump operation, the moving liquid continues to flow out until the liquid level in both tanks is approximately the same level. If it is left as it is, the liquid overflows, the surroundings are soiled, and the contents are very dangerous.

これらのサイホン式ポンプは、移動する液体が 適量になるまで監視し続ける必要があり、また手動で停止させなければならないが、手動停止にはやや手間がかかり 適量以上に流出してしまったり 時には溢れさせてしまう事がある。These siphon pumps need to be monitored until the moving liquid reaches the proper amount, and must be stopped manually, but manual stop is somewhat troublesome and sometimes it flows out more than the proper amount or sometimes overflows. There are things that will let you.

上述のように従来のサイホン式ポンプは停止が手動で 常に監視し続けねばならず、また停止にやや手間がかかるため結局溢れさてしまう危険がある。
このため液体が 可燃性や刺激性のある物の場合 重大な事故を引き起こす可能性がある。
As described above, the conventional siphon pumps must be constantly monitored for stoppage, and there is a danger that the stoppage will eventually overflow because it takes some time and effort.
This can cause serious accidents if the liquid is flammable or irritating.

本発明はこのような点に着目したものであり、目的は液体を移動する際に 密閉加圧や動力源も必要とせずに 液体の移動を一定量で自動停止させるためのものである。The present invention pays attention to such points, and an object thereof is to automatically stop the movement of the liquid by a fixed amount without requiring hermetic pressure or a power source when moving the liquid.

また任意の量で 手動停止させる場合は、たとえ小指一本でも即時に停止させることができる。In addition, when manually stopping at an arbitrary amount, even a single little finger can be stopped immediately.

着脱が簡単で 装置が細く 入り口が小さいタンクにも使用できる。Easy to attach and detach, thin equipment, and can be used for tanks with small entrances.

上述の目的を達成する本発明の自動停止装置は、液体量を検知するフロートと それに連動するエアーバルブを持ち、液体にフロートが浸かる事により、発生した浮力が エアーバルブを押し上げて バルブを開く事により サイホン状態を破りポンプを自動停止させる事を特徴とする。  The automatic stop device of the present invention that achieves the above-mentioned object has a float that detects the amount of liquid and an air valve that operates in conjunction with the float. It is characterized by breaking the siphon state and automatically stopping the pump.

エアーバルブに繋がるロッドを延長する事により 任意の液量でポンプを簡単に手動停止できる特徴がある。By extending the rod connected to the air valve, the pump can be easily manually stopped at any liquid volume.

以上のように本発明により 動力源を使わないサイホン式ポンプを加圧 密閉などの特別な操作を行うことなく適量で自動停止させることができ、灯油ポンプなどに用いれば不注意やタイミングのずれによる溢出を防止する事ができる。As described above, according to the present invention, a siphon pump that does not use a power source can be automatically stopped at an appropriate amount without performing special operations such as pressurization and sealing. Overflow can be prevented.

金属製などの液体量が外から見えないようなタンクにも自動停止により溢出させずに補給できる。Even tanks where the amount of liquid such as metal cannot be seen from the outside can be replenished without overflow by automatic stop.

手動停止する場合は、たとえ小指一本でも簡単に停止させることができ、ポンプ本体に停止用の空気キャップを取り付ける必要がない。In the case of manual stop, even a single little finger can be easily stopped, and there is no need to attach a stop air cap to the pump body.

フロートは装置内に格納され、上下方向に動くだけで側方には移動せず、フロートがタンク壁と接触して停止不能になったりしない。また破損もしにくい。The float is stored in the apparatus, and only moves in the vertical direction and does not move to the side. The float does not come into contact with the tank wall and cannot be stopped. It is also difficult to break.

フロートなどの可動部は、回転部や付着部がなくエアーバルブの上に自重で乗っているだけの構造のため ひっかかりなどのトラブルを起こしにくい。A movable part such as a float does not have a rotating part or attachment part, and has a structure in which it is placed on the air valve by its own weight.

フロートは垂直方向に滑って移動するため側方に場所をとらず 装置を液体の吐出部と細く一体化でき 取り付け時にフロートがじゃまにならず 入り口の小さいタンクにも使用できる。  Since the float slides in the vertical direction, it does not take up any space on the side, so that the device can be integrated with the liquid discharge section finely, so that the float does not get in the way of installation and can be used for a tank with a small entrance.

ポンプ稼動時のエアーバルブは、重力により垂直方向に閉鎖されるため 空気もれによる補給時の動作不良が少ない。  The air valve when the pump is operating is closed in the vertical direction due to gravity, so there are few malfunctions during replenishment due to air leakage.

一度停止した場合、手動で回復操作を行なわない限り 勝手に液体が漏れ出る事がない。Once stopped, liquid will not leak without permission unless manual recovery is performed.

以下、本発明実施の形態を図面に基づき 詳細に説明する。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図1は本発明を実施するための形態を示す、外観および主要部の拡大断面図である。FIG. 1 is an enlarged cross-sectional view of an external appearance and a main part showing an embodiment for carrying out the present invention.

図1に示すように、本自動停止装置は、従来より使われているサイホン式ポンプの吐出口と一体に設置し 本装置からポンプ上部の圧縮減圧部にはエアーパイプ1がとりつけられている。As shown in FIG. 1, the automatic stop device is installed integrally with a discharge port of a conventionally used siphon-type pump, and an air pipe 1 is attached from the device to a compression / decompression unit above the pump.

エアーパイプ1の下端は図のように上向き凹型のカップ状になり 上方からロッド4と一体の凸状の蓋をする事によりエアーバルブ2を形成している。液体量が少ない時にはフロート3及びロッド4とそれに付随する装置の自重によって凸部が垂直下方にカップ状の部分に押し付けられ エアーバルブ2は閉鎖されている。この状態でポンプを稼動させるとサイホン状態となり液体が流出する。The lower end of the air pipe 1 has an upward concave cup shape as shown in the figure, and an air valve 2 is formed by a convex lid integrated with the rod 4 from above. When the amount of liquid is small, the convex part is pressed vertically against the cup-shaped part by the weight of the float 3 and the rod 4 and the accompanying device, and the air valve 2 is closed. When the pump is operated in this state, a siphon state is entered and the liquid flows out.

もし液体がポンプからエアーパイプ1に流入してもエアーバルブ2の凹部から溢れ、ロッド4を通しているパイプ5を下って被補給側のタンク内に入る。パイプ5は吐出される液体の流れが、フロート3やロッド4の動きを妨げたり上方のエアーバルブ2に吹さ上げたりしないようにする役割も持っている。Even if liquid flows into the air pipe 1 from the pump, it overflows from the recess of the air valve 2 and goes down the pipe 5 passing through the rod 4 and enters the tank on the supply side. The pipe 5 also has a role of preventing the flow of the discharged liquid from obstructing the movement of the float 3 and the rod 4 or blowing it up to the upper air valve 2.

液体が吐出パイプ6を通っていくつかの吐出口7から被補給側のタンクに流出すると液面が上昇し、 フロート3が液体に浸かる事により浮力で上方に押し上げられ 繋がったロッド4を介してエアーバルブ2が開放されると、隔壁9に開けられたロッド穴を介して空気がエアーパイプ1を通ってポンプ上部の圧縮減圧部に流入するため サイホン状態が破られポンプは自動停止する。When the liquid flows through the discharge pipe 6 from some discharge ports 7 to the tank on the replenishment side, the liquid level rises, and the float 3 is soaked in the liquid and lifted upward by buoyancy through the connected rod 4 When the air valve 2 is opened, air flows into the compression / decompression unit at the top of the pump through the air pipe 1 through the rod hole formed in the partition wall 9, so that the siphon state is broken and the pump automatically stops.

任意の量で手動停止させるには、ロッド4の先端につけられた把持部8を軽く上方に引き上げる事で エアーバルブ2を手動で開放し、サイホン状態を破りポンプを停止させる。To manually stop at an arbitrary amount, the air valve 2 is manually opened by gently lifting the grip 8 attached to the tip of the rod 4 to break the siphon state and stop the pump.

フロート3及びロッド4とそれに付随する部分は 装置の隔壁9により動きが制限され一定の高さより上方には動かず、エアーバルブ2は、凸部と凹部がずれて はずれたりしないようになっている。The float 3 and the rod 4 and their associated parts are restricted in movement by the partition wall 9 of the apparatus and do not move above a certain height, so that the air valve 2 does not slip out of the convex part and the concave part. .

エアーパイプ1は 吐出パイプ6に貼付あるいは内部を通すことも可能で外観・機能を向上させる事もできる。The air pipe 1 can be affixed to or passed through the discharge pipe 6 to improve the appearance and function.

10は、ポンプと停止装置を所定の位置に固定する弾性部材でできた爪状の止め具である。タンクの突起部にひっかけるなどして使用し ポンプ本体や吐出部を人の手で固定し続ける手間を省き 自動停止する液面の位置を確実にする役割も持つ。タンクの出入口の大きさにあわせて ポンプや自動停止装置に付加するものである。Reference numeral 10 denotes a claw-like stopper made of an elastic member that fixes the pump and the stopping device at a predetermined position. It is used by hooking on the protruding part of the tank, etc. It also has the role of ensuring the position of the liquid surface that stops automatically, eliminating the need to keep the pump body and discharge part fixed by human hands. It is added to the pump and automatic stop device according to the size of the tank entrance.
