본 고안은 액체이송 펌프에 관한 것으로, 특히 대형용기에 담긴 액체를 소형용기에 이송시키는 수동(手動)액체이송 펌프에 관한 것이다.The present invention relates to a liquid transfer pump, and more particularly, to a manual liquid transfer pump for transferring a liquid contained in a large container to a small container.

종래 사용되던 액체이송 펌프로는 주로 제 1 도에 보인것과 같은 것이 사용되었는데, 이는 플라스틱등의 탄성체로 구성되며 벨로우즈(bellows ; 10)의 하부에 이와 연통되는 밸브부(11)를 설치하고, 이에 각각 도입밸브(11a)와 도출밸브(11b)를 구비한 도입관(12) 및 도출관(13)을 연통시켜 되었는데, 도입관(12)의 하단을 액체용기의 액면이하로 담그고 벨로우즈(10)를 손으로 압착시키면 그 내부 공간(10a)의 공기 압력증가에 의해 도출밸브(11b)는 열리고 도입밸브(11a)가 차단되어 공기는 도출관(13)측으로 빠져나가고, 손을 놓으면 탄성재질로 된 벨로우즈(10)의 복원력에 의해 발생된 부압(負壓)으로 돌출밸브(11b)가 차단되고 도입밸브(11a)가 열려 액체는 밸브부(11) 및 벨로우즈(10)의 내부공간(10a)에 충만된다.The liquid transfer pump used in the related art is mainly used as the one shown in FIG. 1, which is composed of an elastic body such as plastic and installs a valve part 11 communicating with the lower part of the bellows 10. An introduction tube 12 and an introduction tube 13 each having an inlet valve 11a and an inlet valve 11b communicate with each other. The lower end of the inlet tube 12 is immersed below the liquid level of the liquid container and the bellows 10 is connected. When pressing by hand, the inlet valve 11b is opened and the inlet valve 11a is blocked by the increase in the air pressure of the inner space 10a, and the air escapes to the outlet tube 13 side, and when released, the elastic material The protruding valve 11b is blocked by the negative pressure generated by the restoring force of the bellows 10 and the inlet valve 11a is opened to open the liquid into the valve portion 11 and the inner space 10a of the bellows 10. Being filled.

이와같은 작동을 수차 반복하여 벨로우즈(10)내의 압력이 평형되고 나면 사이폰(siphon)의 원리에 의해 액체는 이송을 계속하고, 충분한 양을 이송시키었다고 판단될 때에는 캡(14)을 열어 압력 배출 구멍(10b)으로 공기를 공급함으로써 액체의 이송을 중단시킨다.After repeating this operation several times and the pressure in the bellows 10 is balanced, the liquid continues to be transferred by the principle of siphon, and when it is determined that the sufficient amount is transferred, the cap 14 is opened to release the pressure. The supply of air to the hole 10b stops the transport of the liquid.

그러나 이와 같은 종래의 액체이송 펌프는 연속 이송만을 전제로 한 것이므로 정확한 양을 공급(소위 미터링(metering))할 수가 없어서, 기계등에 윤활유를 공급하는 경우에는 과대한 양이나 과소한 양을 공급하게되어 윤활유의 손실이 많거나 기계의 손실을 가져올 우려가 있었으며, 이에 따라 종래의 액체이송 펌프는 기껏해야 가정의 석유이송등의 목적에 사용되던 것이 고작이었다.However, since the conventional liquid transfer pump is based on continuous transfer only, it is impossible to supply the correct amount (so-called metering). Therefore, when lubricating oil to a machine or the like, an excessive amount or an excessive amount is supplied. There was a risk of loss of lubricating oil or loss of machinery, and accordingly, the conventional liquid transfer pump was only used for the purpose of oil transfer at home.

뿐만아니라 펌프내에 잔류한 액체가 이송완료한 누출되어 주변을 오염시키는 문제도 있었으며, 펌프가 용기에 고정될 수가 없어서 연속 이송중 펌프가 넘어져 이송이 중단되거나 주변을 오염시키는 문제점도 있었다.In addition, there was a problem that the liquid remaining in the pump is leaked to complete the transfer, polluting the surroundings, the pump can not be fixed to the container, the pump falls down during the continuous transfer, the transfer is stopped or polluted the surroundings.

또한 도입관의 길이가 한정되어 액체 용기내의 액면과의 적절한 조정이 불가능 하였을뿐 아니라 용기 하부에 침전된 불순물이 그대로 혼입되어 펌프 또는 장비를 폐색시키거나 손상시키는 문제점이 있었다.In addition, the length of the introduction pipe is limited, and the proper adjustment with the liquid level in the liquid container is not possible, and the impurities deposited in the lower part of the container are mixed as it is, which causes a problem of blocking or damaging the pump or the equipment.

이와같은 종래의 문제점을 감안하여 본 고안의 목적은 정확한 양의 액체를 공급할 수 있을뿐 아니라 연속이송도 가능한 액체 이송 펌프를 제공하는 것이다.In view of such a conventional problem, an object of the present invention is to provide a liquid transfer pump capable of supplying an accurate amount of liquid as well as continuous transfer.

본 고안의 다른 목적은 액체 이송의 개시 및 중단을 정확히 할 수 있도록 함으로써 불필요한 공급이나 누출을 방지 할 수 있는 액체 이송 펌프를 제공하는 것이다.Another object of the present invention is to provide a liquid transfer pump which can prevent the unnecessary supply or leakage by enabling accurate start and stop of the liquid transfer.

본 고아의 또 다른 목적은 용기의 종류와 무관하게 펌프를 이에 고정할 수 있으며 도입관의 길이를 액면의 위치에 따라 조정할 수 있는 액체 이송 펌프를 제공하는 것이다.Another object of the orphan is to provide a liquid transfer pump which can fix the pump to it regardless of the type of container and which can adjust the length of the introduction tube according to the position of the liquid level.

본 고안의 또 다른 목적은 용기에 혼입되거나 하부에 침전된 불순물을 차단할 수 있는 액체이송 펌프를 제공하는 것이다.Still another object of the present invention is to provide a liquid transfer pump capable of blocking impurities incorporated into a container or settled at the bottom thereof.

상술한 여러 목적을 달성하기 위해 본 고안 액체 이송펌프는 투명 재질로 투명실린더를 형성하여 표면에 내부 액체량을 표시하는 표시 눈금을 각인하고, 그 일측에는 콕을 통해 도출관을 연결하고 그 상측에는 압력이 유통되는 탄성압력실을 연통시키며, 도입관은 투명 실린더의 내부 상면으로부터 소정거리 떨어진 위치에서부터 연장되어 하방외부까지 관통설치되어 구성되는 것을 특징으로 한다.In order to achieve the above-mentioned various objects, the liquid transfer pump of the present invention forms a transparent cylinder made of a transparent material, and imprints a mark on the surface indicating the amount of liquid, and on one side thereof, a lead pipe is connected through a cock, and It communicates with the elastic pressure chamber through which the pressure flows, the introduction tube is characterized in that it is configured to extend from a position away from the inner upper surface of the transparent cylinder through a downward installation.

본 고안의 다른 특징은 상술한 구성에 있어서, 투명실린더의 하면 도입관의 둘레에 탄성재질로 되며 그 외주에 경사면에 형성된 결합 패킹을 부착하여 구성되는 것을 특징으로 한다.Another feature of the present invention is characterized in that in the above-described configuration, the lower surface of the transparent cylinder is made of an elastic material and attached to the outer periphery of the coupling packing formed on the inclined surface.

본 고안의 이러한 특징 및 기타 또 다른 특징과 잇점을 바람직한 실시예의 설명에서 더욱 명확해질 것이므로 이하 본 고안을 바람직한 한 실시예를 통해 상세히 설명한다.These and other still further features and advantages of the present invention will become more apparent from the description of the preferred embodiments, which will be described in detail with reference to the following invention.

본 고안 액체 이송 펌프는 제 2 도에 보는 바와 같이 투명한 합성수지 또는 유리등 투명체로된 투명 실린더(1)를 형성하여 그 표면에 액체량을 표시할 수 있는 표시눈금(2)을 각인하고, 투명실린더(1)의 하부 일측에는 콕(cock ; 3)을 통해 도출관(4)을 연장하며, 투명실린더(1)의 상부에는 이와 압력이 유통되며 고무나 플라스틱 등 탄성재질로된 탄성 압력실(5)을 연통시키고, 상기 투명실린더(1)의 내부에는 그 상면으로부터 소정거리 이격된 위치로부터 그 외부로 연장되는 도입관(6)을 관통 설치함으로써 구성된다.The liquid transfer pump of the present invention forms a transparent cylinder 1 made of a transparent synthetic resin or a transparent body such as glass, as shown in FIG. 2, and imprints a display scale 2 capable of displaying the amount of liquid on the surface thereof. One side of the lower portion (1) extends the lead-out pipe (4) through a cock (cock) (3), the pressure is distributed in the upper portion of the transparent cylinder (1) and the elastic pressure chamber made of an elastic material such as rubber or plastic (5) ) Is communicated with each other, and the inside of the transparent cylinder 1 is provided with a penetrating introduction tube 6 extending outward from a position spaced a predetermined distance from an upper surface thereof.

투명 실린더(1)의 하면, 도입관(6)의 둘레에는 내수성, 내유성이 풍부하며 탄성재질인 고무등으로 그 외주에 경사부(taper ; 7a)를 형성한 결합 패킹(packing ; 7)을 부착한다.On the lower surface of the transparent cylinder 1, around the inlet pipe 6, water- and oil-resistant, elastic rubber or the like is attached to the joint (packing; 7) formed with a tapered portion (7a) on the outer periphery do.

상술한 탄성 압력실(5)은 제 3 도(a)에 보인것처럼 고무를 구형(ball)로 형성하여 구형 압력실(5')로 구성하는 것이 작동에 편리하나, 종래와 같은 벨로우즈 압력실(5")로 한 구성도 물론 가능하다.(제 3 도(b))The elastic pressure chamber 5 described above is convenient to operate by forming a rubber ball into a spherical pressure chamber 5 'as shown in FIG. 3 (a). 5 ") is, of course, possible. (FIG. 3 (b))

이와같이 구성된 본 고안 액체 이송 펌프는 다음과 같이 정량공급, 연속공급, 분할공급등 3가지 모드(mode)로 작동될 수 있다.The liquid transfer pump of the present invention configured as described above can be operated in three modes, such as metered feeding, continuous feeding, and split feeding.

첫번째 작동 모드는 정량공급(metering)모드로서 먼저 액체용기(V)의 용기입구(V')를 통해 도입관(6)을 삽입하여 하방으로 누르면 경사면(7a)을 가진 결합 패킹(7)은 용기입구(V')에 끼워져 본 고안 펌프를 탄성 지지하게 된다. 다음 탄성 압력실(5)의 압력 배출구멍(5a)을 개방한채 탄성 압력실(5)을 압착시켜 내부의 공기를 배출시킨 뒤, 압력 배출구멍(5a)을 차단하면 탄성 압력실(5)의 복원력에 의해 부압이 발생되므로 액체용기(V)내의 액체(Lv)는 도입관(6)을 따라상승하여 그 상부(6a)로 넘치게 되고, 넘친 액체(Lp)는 투명실린더(1)의 하부에 고이게 된다. 이때 그 외부에 각인된 표시눈금(2)을 판독하여 적정량에 도달한 뒤 압력 배출구멍(5a)을 개방하면 공기가 공급되어 부압이 해제 되므로 도입관(6)내에 있던 액체(Li)는 자중에 의해 다시 액체용기(V)내로 낙하하게 되어 투명실린더(1)내에는 정확한 양의 액체(Lp)가 잔류하게 된다. 이때 콕(3)을 열면 투명실린더(1)내의 액체(Lp)는 도출관(4)을 통해 소요 용기로 공급됨으로써 정량공급이 이뤄지게 된다(이때 도입관의 상부(6a)는 투명실린더(1)내의 액면보다 상부에 있다).The first mode of operation is metering mode. First, the inlet tube 6 is inserted through the container inlet V 'of the liquid container V and pushed downward so that the combined packing 7 having the inclined surface 7a is a container. It is fitted to the inlet (V ') to elastically support the present invention pump. Next, the elastic pressure chamber 5 is pressed while the pressure discharge hole 5a of the elastic pressure chamber 5 is opened to discharge air therein, and the pressure discharge hole 5a is blocked to block the pressure discharge hole 5a. Since the negative pressure is generated by the restoring force, the liquid Lv in the liquid container V rises along the introduction pipe 6 and overflows to the upper portion 6a, and the overflowed liquid Lp is lowered to the lower portion of the transparent cylinder 1. Going. At this time, after reading the indication scale 2 stamped on the outside and reaching the proper amount, if the pressure discharge hole 5a is opened, air is supplied and the negative pressure is released. This causes the liquid L to fall back into the liquid container V, so that the correct amount of liquid Lp remains in the transparent cylinder 1. At this time, when the cock 3 is opened, the liquid Lp in the transparent cylinder 1 is supplied to the required container through the lead-out pipe 4 so that the quantitative supply is made (in this case, the upper portion 6a of the inlet pipe is the transparent cylinder 1). Above the liquid level inside).

다음 연속 공급 모드는 정량공급 모드에서와 같이 투명실린더(1)의 상부에 액체(Lp)를 공급하여 그 액면이 도입관(6)의 상부(6a)보다 놓아졌을 때 콕(3)을 개방하면, 도입관(6)으로부터 유입된 액체(Li)는 사이폰의 원리에 의해 도출관(4)으로 연속 유출됨으로써 연속 공급이 이루어지게 된다(이때 압력 배출구멍(5a)은 계속 차단된 상태에 있다).The next continuous supply mode supplies the liquid Lp to the upper part of the transparent cylinder 1 as in the metering mode and opens the cock 3 when the liquid level is lower than the upper part 6a of the inlet tube 6. The liquid Li introduced from the introduction pipe 6 is continuously discharged to the lead-out pipe 4 according to the principle of siphon, so that the continuous supply is made (at this time, the pressure discharge hole 5a is kept blocked. ).

다음 분할공급모드는 정량공급모드에서와 같이 투명실린더(1)의 하부에 액체(Lp)를 공급한 뒤, 본 고안 펌프를 액체 용기(V)로부터 이탈시켜 소요 공급위치(예를 들어 윤활유의 급유위치등)로 이동시켜 콕(3)을 개방하여 소정량을 공급하는 작업을 반복할 수 있다(이때 투명 실린더(1)의 하부에 담긴 액체(Lp)의 액면보다 도입관(6)의 상부(6a)가 높으므로 액체용기(V)로부터 분리하여 이동시켜도 콕(3)을 열지 않는 한 액체(Lp)는 외부로 누출되지 않는다).In the next divided supply mode, the liquid Lp is supplied to the lower part of the transparent cylinder 1 as in the fixed supply mode, and then the pump of the present invention is removed from the liquid container V to supply the required supply position (for example, lubrication oil supply). Position and the like, and the operation of opening the cock 3 to supply a predetermined amount can be repeated (at this time, the upper portion of the introduction pipe 6 than the liquid level of the liquid Lp contained in the lower portion of the transparent cylinder 1 ( Since 6a) is high, the liquid Lp does not leak to the outside unless the cock 3 is opened even if it is moved away from the liquid container V).

상술한 실시예뿐 아니라 본 고안 액체 이송 펌프는 다음과 같은 응용도 가능하다.In addition to the above-described embodiments, the present invention liquid transfer pump may also have the following applications.

즉, 액체를 공급하여야 할 입구가 작은 경우(예를 들어 기계의 주유구등) 도출관(4)의 선단에 노즐(nozzle ; 4a)을 결합함으로써 이에 맞추는 구성도 가능하고, 용기내 액체의 액면 변화에 대응하여 그 길이를 조절할 수 있도록 도입관(6)의 선단에 맞춤턱 또는 나사로 된 결합부(6b)를 형성하여 연장관(8)을 연장하는 구성 역시 가능하다(제 4 도 참조), 또 도입관(6) 또는 연장관(8)의 선단에는 액체내의 불순물의 유입을 방지하기 위해 적절한 필터(filter ; 9)를 설치하는 것이 바람직하다.That is, in the case where the inlet to supply liquid is small (for example, an oil inlet of a machine), a configuration can be adapted by combining a nozzle 4a to the tip of the lead-out pipe 4, and the liquid level change of the liquid in the container is possible. It is also possible to extend the extension tube 8 by forming the engaging portion 6b of the fitting jaw or screw at the tip of the introduction tube 6 so as to adjust its length in response thereto (see FIG. 4). It is preferable to install an appropriate filter 9 at the tip of the tube 6 or the extension tube 8 to prevent the ingress of impurities in the liquid.

이와같이 본 고안 액체 이송 펌프는 정확한 양의 액체공급이 가능할 뿐 아니라 종래와 같은 연속 공급도 가능하며, 사용중 액체용기에 고정될 수 있을뿐 아니라 이를 분리하여 이동 사용도 가능하고, 사용완료시 액체가 즉시 차단될 수 있어 액체의 누출에 의한 오염이나 손실이 없으며, 액체내의 불순물이 펌프나 기계등에 유입되지 않아 그 폐색이나 손상등의 우려가 없고, 액체 용기가 공급될 용기의 크기나 액면의 위치에 따라 조절이 가능한 여러 가지 이점이 있다.In this way, the liquid transfer pump of the present invention is not only capable of supplying the correct amount of liquid, but also capable of continuous supply as in the prior art, and is not only fixed to the liquid container during use, but also can be separated and moved for use. It can be blocked, so there is no contamination or loss due to leakage of liquid, no impurities in the liquid do not flow into the pump or machine, and there is no fear of blockage or damage, depending on the size of the container to be supplied or the position of the liquid level. There are several advantages that can be adjusted.
