본 고안은 챔버, 밸브 배관 등의 기밀을 요하는 장치의 내용물의 누설 여부를 측정하는데 주로 사용되게 한 압력 누설 탐지기에 관한 것이다.The present invention relates to a pressure leak detector that is mainly used to measure the leakage of the contents of a device that requires airtightness such as a chamber, a valve pipe.
종래에도 챔버, 밸브, 배관 등의 기밀을 요하는 장치에 있어 이의 내용물의 압력 누설을 탐지하기 위한 장치가 여러 가지로 알려지고 있으나 이 가운데 있어 할겐 또는 헬륨 등의 가스를 이용한 누설 탐지 방법이 가장 많이 이용되고 있다.Conventionally, various devices for detecting pressure leakage of the contents of chambers, valves, pipes, and the like are known, but among these, leak detection methods using gas such as halogen or helium are most frequently used. It is used.
그러나 이들 방법은 연속 작업이 불가능 할 뿐만 아니라 미량의 누설은 탐지가 불가능하며 또한 이는 측정시간이 장시간 소요(수압법 기포 관측법)되는 폐단과 대량의 누설 시는 탐지하기 어려운 문제점이 있을뿐만 아니라 장비의 구입 가격이 고가인점 등의 문제점이 있어 단순상품으로서 대량 생산을 하고 있는 산업체에서는 적용되기 힘든 형편이기 때문에 이들 업체에서는 전체 생산품을 검사할 수 없어서 표본 추출에 의한 검사가 이루어지고 있는 실정이므로 제품의 불량률을 개선하지 못하고 있는 실정인 것이다.However, these methods are not only capable of continuous operation, but are not able to detect a small amount of leakage, which is not only difficult to detect in case of large leaks and leakages that require a long measurement time (hydraulic bubble observation). Since the purchase price is high and there are problems such as high price, it is difficult to apply to the industry which is mass production as a simple product, so these companies cannot inspect the whole product, so the inspection by sampling is performed. The situation is not improving the defective rate.
본 고안은 이상의 문제점을 해결하고자 안출한 것으로 이의 고안 요지는 내압 및 누설 측정을 동시에 수행할 수 있으며 대량의 물품을 자동 클램핑시켜 간단히 측정할 수 있게한 것이다.The present invention has been made to solve the above problems, and the subject matter of the present invention is to be able to perform the internal pressure and leakage measurement at the same time, it is possible to measure simply by automatically clamping a large number of articles.
이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.
함체 형상인 몸체(1)의 내부에 격판(1')을 개재시켜 진공 탐지실(3) 및 진공실(4)을 형성하되 진공 탐지실(3)과 진공실(4)은 격판(1')에 뚫림된 통공(2)을 통해 연통되어지며 진공 탐지실(3)의 일측에 연결된 호스(8)에는 밸브(7)를 개재시킨 상태에서 그 외단에는 클램프(9)에는 측정하고자하는 시료(10)를 연결할 수 있게하고 진공실(4)의 외측에는 진공 펌프(6)가 연결관(5')에 의해 연결되어진 구조이다.The vacuum detection chamber 3 and the vacuum chamber 4 are formed by interposing a diaphragm 1 'inside the body 1 having a shape of an enclosure, but the vacuum detection chamber 3 and the vacuum chamber 4 are connected to the diaphragm 1'. The sample 10 to be measured in the clamp 9 at the outer end thereof while the valve 8 is connected to the hose 8 connected to one side of the vacuum detection chamber 3 through the drilled through hole 2. And a vacuum pump 6 is connected to the outside of the vacuum chamber 4 by a connecting pipe 5 '.
이상과 같이 구성된 본 고안은 압력 누설 탐지기인바 이를 사용할 시는 호스(8)에 연결된 클램프(9)에 실험하고자하는 시료(10)를 기밀될 수 있게 연결한 상태에서 밸브(7)를 열고 진공 펌프(6)를 가동시켜 진공 탐지실(3)과 진공실(4)이 진공 상태가 되게한다.The present invention configured as described above is a pressure leak detector, when using the vacuum pump to open the valve (7) in a state in which the sample (10) to be tested is hermetically connected to the clamp (9) connected to the hose (8) (6) is operated to bring the vacuum detection chamber 3 and the vacuum chamber 4 into a vacuum state.
이와 같이 진공시킨 상태에서 진공펌프(6)의 가동을 중지시키면 이때 시료(10)의 압에 이상이 없을때는 진공실(4)과 진공탐지실(3)의 압력계는 진공 상태임을 표시하고 시료(10)에 압이 누설될 시는 누설압이 압력 탐지실(3)내에 장치된 압력계(5)에 표시되어진다.When the operation of the vacuum pump 6 is stopped in the vacuumed state as described above, when there is no abnormality in the pressure of the sample 10, the pressure gauges of the vacuum chamber 4 and the vacuum detection chamber 3 indicate that the vacuum state and the sample 10 When the pressure leaks into the pressure gauge, the leak pressure is displayed on the pressure gauge 5 installed in the pressure detection chamber 3.
이때의 누설압의 측정은 진공실(4)내에 장치된 압력계(5')와의 대비차에서 그 수치를 알수 있으며 이 수치 계산은 압력계(5)(5')와 연결된 컴퓨터(도면생략)에서 처리하여 표시되어진다.At this time, the leakage pressure can be determined from the difference between the pressure gauge 5 'installed in the vacuum chamber 4, and the numerical calculation is performed by a computer (not shown) connected to the pressure gauge 5 (5'). Is displayed.
그리고 격판(1')에 뚫림된 통공(2)은 진공 탐지실(3)과 진공실(4)의 용적에 따라 이에 알맞는 크기로 뚫림하면되고 진공 탐지실(3)에 유입된 압이 한정치를 초과하면 이때에는 통공(2)을 통해 진공실(4)에 유입되고 진공실(4)에 유입된 압이 한정치에 달하면 이때에는 센서가 이를 감지하여 진공 펌프(6)를 가동시키게 된다.In addition, the through hole 2 drilled through the diaphragm 1 ′ may be drilled to an appropriate size according to the volume of the vacuum detection chamber 3 and the vacuum chamber 4, and the pressure introduced into the vacuum detection chamber 3 may be limited. If exceeded at this time, if the pressure introduced into the vacuum chamber 4 through the through hole 2 and the pressure introduced into the vacuum chamber 4 reaches a limited value, the sensor detects this and starts the vacuum pump 6.
그리고 시료(10)의 압력 누설 여부를 연속하여 탐지하고자할 시는 클램프(9)의 조작으로 탐지 완료된 시료를 제거하고 새로운 시료(10)를 클램핑시키면 된다.And if you want to continuously detect whether or not the pressure of the sample 10 leaks, the sample is detected by the operation of the clamp 9 is removed and the new sample 10 is clamped.
그리고 본 고안의 시료는 배관 장치의 압력 누설 탐지의 경우를 예시한 것이나, 이를 챔버나 밸브 등의 압력 누설 탐지에도 이용할 수 있는 것이다.In addition, the sample of the present invention exemplifies the case of pressure leak detection of the piping device, it can be used for pressure leak detection of the chamber or valve.
이상과 같이 본 고안은 가장 간단한 구조로서 시료의 압력 누설 여부를 연속적으로 탐지할 수 있게 하였기 때문에 생산성 제고에 크게 기여할 수 있어 매우 실용적이다.As described above, the present invention is the simplest structure, and thus it is possible to continuously detect whether the sample leaks pressure, and thus it is very practical because it can greatly contribute to the improvement of productivity.
