Description
제1도는 소형 압축탱크가 부착된 자동펌프의 전체 조립도.1 is an overall assembly of the automatic pump with a compact compression tank.
제2도는 종래 사용되던 소형 압축탱크의 단면도.2 is a cross-sectional view of a compact compression tank conventionally used.
제3도는 본 고안의 다이아 후램이 적용된 소형 압축 탱크 단면도.3 is a cross-sectional view of a compact compression tank to which the diaphragm of the present invention is applied.
제4도는 제3도의 상태에서 다이아 후램이 줄어든 상태도.4 is a diagram showing a reduced diaphragm in the state shown in FIG.
본 고안은 자동식 펌프용 소형 압축탱크의 다이아후램에 있어서 그 내면의 접착방지장치에 관한 것이다.The present invention relates to a device for preventing adhesion on the inner surface of a diaphragm of a compact compression tank for an automatic pump.
일반적으로 자동식 펌프의 소형 압축탱크(1)는 제1도 및 제2도에서와 같이 가스밸브(2)를 통하여 압축공기실(3)내에 압력스위치의 접점이 떨어지는 압력의 0.9배에 해당하는 공기 또는 질소가스를 넣고 펌프의 공기분리실에 결합하여 수실(4)내의 물과 압축공기실(3)의 공기압력조정으로 압력 스위치의 접점을 열고 닫아 자동운전이 되도록하는 역활을 하는 것이다.In general, the compact compression tank 1 of the automatic pump has air equal to 0.9 times the pressure at which the contact point of the pressure switch falls in the compressed air chamber 3 through the gas valve 2 as shown in FIGS. 1 and 2. Alternatively, the nitrogen gas is added to the air separation chamber of the pump, and the pressure of the water in the water chamber 4 and the air pressure of the compressed air chamber 3 are adjusted to open and close the contact of the pressure switch so that the automatic operation is performed.
또한 소형 압축탱크(1)는 공기가 다이아 후램(5)에 의해 분리되어 있어 물에 녹지 않아 줄어들지 않게 되며 공기 보급장치가 필요없고 소형 경량이므로 설치 및 사용이 용이하다.In addition, the compact compression tank (1) is separated by the diaphragm (5) is not dissolved in the water does not shrink, does not need an air supply device and is easy to install and use because it is compact and lightweight.
이러한 종래의 소형 압축탱크(1)는 내부의 수실(4)과 압축공기실(3)을 분리시키면서 용적변화에 따른 압력변화를 전달하는 다이아 후램(5)이 중요한 기능부로서 존재하지만 펌프를 장기간 사용하지 않을 때는 수실(4)내의 물을 빼버리므로 다이아 후램(5)이 오므라들어서 서로 접착됨에 의해 기능을 상실하게 되기 때문에 이러한 접착현상을 방지하기 위해 중앙부에 별도의 지지대(6)를 입설시켜 주게 된다.The conventional compact compression tank 1 has a diaphragm 5 which transmits a pressure change according to a volume change while separating the internal water chamber 4 and the compressed air chamber 3, but exists as an important functional part. When not in use, the water in the water chamber 4 is drained, so that the diaphragm 5 retracts and loses function by being bonded to each other. Therefore, a separate support 6 is placed in the center to prevent such adhesion. do.
그러나지지대(6)를 수실(4) 내측에 장치하려면 작업의 어려움과 번거러움이 많고 부품수가 늘어나는 등의 제작공정 및 제작가의 상승요인이 되는 문제점이 뒤따르며 정중앙부만을 격리시킬 수 있게된 것이다.However, if the support 6 is installed inside the water chamber 4, the manufacturing process and the rising factor of the manufacturer, such as a lot of difficulty and cumbersome work and increase in the number of parts, can be isolated and only the central portion can be isolated.
본 고안은 이러한 종래의 문제점을 시정보완해서 지지대가 없이 다이아 후램자체로서 접착이 방지될 수 있도록 함을 목적으로 안출한 것으로 이를 첨부 도면에 의해서 상세히 설명하면 다음과 같다.The present invention has been devised for the purpose of preventing adhesion as a diaphragm itself without a support by solving such a conventional problem as described in detail by the accompanying drawings as follows.
탱크(1) 내측에 압축 공기실(3)과 수실(4)을 구분하는 다이아 후램(5)을 설치하는 것에 있어서 다이아후램(5)의 내면부 전체에 적당간격으로 다수의 돌기(7)를 돌설하여 내면끼리 접착됨을 방지할 수 있게 함을 특징으로 한 것이다.In installing the diaphragm 5 separating the compressed air chamber 3 and the water chamber 4 inside the tank 1, a plurality of protrusions 7 are provided at suitable intervals over the entire inner surface of the diaphragm 5. It is characterized by being able to prevent the inner surfaces are bonded to each other.
도면중 미설명부호 8은 니플이다.In the figure, reference numeral 8 denotes a nipple.
이와같이 된 본 고안은 펌프를 장기간 사용하지 않을 때는 수실(4)내에 물이 없게되므로 압축공기실(3)내의 공기압력으로 인해 다이아 후램(5)이 줄어들어도 내면부의 돌기(7)가 제3도 및 제4도에서와 같이 서로 맞닿게 되지만, 이들 돌기(7)의 사이사이마다는 공기 유통로가 형성되고 면접촉이 아닌 점접촉방식으로 접지되기 때문에 완전히 붙지 않고 맞닿아 있는 상태로 있게되어 압축공기실(3)의 압력이 소멸되거나 또는 수실(4)내에 물이 공급되면 접지상태가 쉽게 떨어지면서 즉시 원상태로 복귀될 수 있게 된다.In the present invention, when the pump is not used for a long time, there is no water in the water chamber 4, so even if the diaphragm 5 is reduced due to the air pressure in the compressed air chamber 3, the projections 7 on the inner surface of the pump 3 are And in contact with each other as shown in FIG. 4, but the air flow path is formed between each of the protrusions 7 and is grounded by a point contact method instead of a surface contact, so that they are in contact with each other without being completely compressed. When the pressure in the air chamber 3 is extinguished or water is supplied into the water chamber 4, the grounding state is easily dropped and can be returned to its original state immediately.
이렇게된 본고안은 수실(4)내에 지지대(6)를 삭제시키는 대신에 다이아 후램(5) 내면을 돌기(7)로 형성하였기 때문에 그 내면부가 서로 붙을 염려가 없게 됨과 동시 부품수를 줄이면서 공정도 간단해지고 구조가 간단해지므로 제작가를 절감시킬 수 있으며 다이아 후램(5)의 정확한 작동을 기대할 수 있는 효과를 가진다.In this case, instead of removing the support 6 in the chamber 4, the inner surface of the diaphragm 5 is formed by the projection 7, so that the inner surfaces of the diaphragm are not attached to each other and the number of parts is reduced. Also, since the structure is simplified and the structure is simple, the manufacturing cost can be reduced, and the accurate operation of the diaphragm 5 can be expected.
