Description
본 고안은 액화가스용 수동감지 액면계에 관한 것으로서, 상세하게는 액화가스가 충진된 고압탱크에 적용하여 수동으로 액화가스량을 안전하게 측정하도록 자성체가 구비된 부자의 재질이나 성상을 특정하고, 액면 측정시 사용편의성이 향상되도록 줄자 타입으로 제작된 측정자를 구비한 액면계에 관한 것이다.The present invention relates to a manual sensing liquid level gauge for liquefied gas, and in particular, it is applied to a high-pressure tank filled with liquefied gas to specify a material or property of a rich person equipped with a magnetic material to safely measure the amount of liquefied gas, The present invention relates to a liquid level meter having a measuring instrument manufactured in a tape measure type to improve usability.
종래에도 탱크로리나 고압탱크에서 유입된 저장물의 액면을 측정하기 위한 측정장비 중 자성체의 자력을 이용하여 액면 높이를 측정하는 방식의 액면계가 있었다.Conventionally, there has been a liquid level gauge that measures the liquid level using magnetic force of a magnetic material among the measuring equipment for measuring the liquid level of the storage flowed from the tank lorry or high pressure tank.
상기 방식의 액면계는 일본 공개실용신안공보 소화 제55-155929호에서 기술되고 있는데, 비자성재질로 개방된 상부구조를 가진 안내관;과, 자성체가 구비되어 상기 안내관과 외주면에 이격되게 설치하여 저장물질에 부유되는 부자;와, 하단부에 자성체가 부착되어 상기 안내측에 삽입하여 상기 부자에 구비된 자성체와 반응하여 저장물질의 액면 높이를 측정할 수 있는 측정자로 구성된다.The liquid level gauge of the above method is described in Japanese Laid-Open Utility Model No. 55-155929, which includes a guide tube having an upper structure opened with a nonmagnetic material; and a magnetic material is provided to be spaced apart from the guide tube and an outer circumferential surface thereof. A rich man suspended in the storage material; and a magnetic body attached to the lower end and inserted into the guide side to measure the liquid level of the storage material by reacting with the magnetic material provided in the rich man.
그리고, 본 출원인의 선출원 고안인 한국실용신안 등록 제 0303971호(명칭:자성체를 이용한 수동 감지형의 액화가스용 액면계)는 안내관과 부자, 측정자를 구비하되 이물질의 유입이 방지되게 뚜껑을 구비하고, 상기 안내관의 재질을 플라스틱류, 스테인레스스틸 또는 내압유리로 한정하거나, 부자의 재질을 티타늄이나 스테인레스스틸로 한정한 것으로 액화가스가 저장된 탱크로리나 매몰탱크에 설치하여 저장된 액화가스의 액면을 측정하도록 한 것이다.In addition, the Korean Utility Model Registration No. 0303971 (name: manual sensing type liquid level gauge for liquefied gas using magnetic material) of the present applicant is provided with a guide tube, a rich person, and a measurer, but has a lid to prevent foreign substances from entering. To limit the material of the guide tube to plastics, stainless steel or pressure-resistant glass, or to limit the material of the rich material to titanium or stainless steel, to be installed in a tank lorry or a buried tank in which liquefied gas is stored to measure the liquid level of the stored liquefied gas It is.
그러나, 액화가스가 저장된 탱크로리나 고압탱크에 상기 인용들과 같은 액면계를 적용할 경우, 액화가스가 저장된 고압탱크에서는 탱크내압이 높아 부자가 쉽게 찌그러들어 고압탱크 바닥면으로 침전되거나, 안내관 외주면에 설치된 부자와 측정자에 구비된 자성체간의 인력으로 상기 부자가 끌어올려져 액면의 높이를 측정하지 못하는 문제점이 있는 등 당산업분야에서 실제적으로 적용할 수 없는 문제점이 있었다.However, when the liquid level gauge as described above is applied to a tank lorry or a high pressure tank in which the liquefied gas is stored, the internal pressure of the tank is high in the high pressure tank in which the liquefied gas is stored, so that the rich easily collapses and precipitates at the bottom of the high pressure tank, There is a problem that can not be practically applied in the industry, such as there is a problem that the rich is pulled up by the attraction between the installed rich and the magnetic material provided in the measuring device to measure the height of the liquid level.
또한, 종래 측정자는 봉 또는 바형태로 형성되어 있어 액면을 측정하기 위해 액면 높이에 부유된 부자 위치를 감지하도록 측정자를 상방으로 올려야 되기 때문에, 고압탱크 상방에 고압탱크 깊이만큼의 측정자를 위한 공간이 필요하게 된다. 고압탱크의 깊이는 다양하지만 깊이가 3,000 ~ 5,000mm인 탱크는 이에 상응하는 공간이 상기 고압탱크 상방에 구비되어야 함으로써 설비비용이 증가되고 편의성이 떨어지는 등의 문제점이 있었다.In addition, the conventional measuring device is formed in the form of a rod or bar, so in order to measure the liquid level, the measuring instrument must be lifted upward to sense the position of the rich man at the height of the liquid level. It is necessary. The depth of the high pressure tank is varied, but the tank having a depth of 3,000 to 5,000 mm has a problem that the corresponding space should be provided above the high pressure tank, thereby increasing the installation cost and lowering the convenience.
본 고안은 이상과 같은 문제점을 해결하기 위한 것으로서,The present invention is to solve the above problems,
안내관과 부자, 측정자로 구성되는 수동감지형 액면계를 액화가스가 충진되어 내압이 높은 고압탱크나 탱크로리에 적용하고, 설비시설을 용이하게 구축하여 편의성과 비용 절감을 목적으로 하며,A manual sensing liquid level meter consisting of a guide tube, a rich man, and a measuring instrument is applied to a high pressure tank or a tank lorry with high liquefied gas filled with liquefied gas.
이를 위하여 비중이나 무게, 크기를 특정하여 표준화시킨 부자와 줄자 형태로 제작한 측정자로 이루어진 액면계를 제공한다.To this end, it provides a liquid level meter consisting of a measurer made in the form of a rich and tape measure by specifying specific gravity, weight, and size.

본 고안 액화가스용 수동감지 액면계는 안내관(10)과 측정자(30), 부자(30)로 구성되며, 액화가스의 저장이나 이송을 위해 매몰탱크(1)나 탱크로리(1) 등 고압탱크(1)에 설치된다.The manual sensing liquid level gauge for liquefied gas of the present invention is composed of a guide tube 10, a measuring instrument 30, and a rich man 30, and a high pressure tank such as a buried tank 1 or a tank lorry 1 for storing or transporting liquefied gas. 1) is installed.
안내관(10)은 상기 고압탱크(1)에 수직방향으로 설치된다. 안내관(10)의 상부는 측정자(20)가 삽입되게 개방된 구조로 이루어지며, 안내관(10)의 상부와 하부가 고압탱크(1)에 나사접합이나, 용융접합, 플랜지 이음방식 또는 통상의 결합방식이 적용될 수 있다.Guide tube 10 is installed in the vertical direction to the high pressure tank (1). The upper part of the guide tube 10 is made of a structure that is open to insert the measurer 20, the upper and lower portions of the guide tube 10 is screw-bonded to the high pressure tank 1, melt-bonded, flanged joint method or the May be applied.
상기 안내관(10)은 비자성체 재질로 제작하는데, 일반 유류 등의 저장을 위한 탱크에서는 내압플라스틱류, 내압유리가 사용되나, 액화가스가 충진된 고압탱크내부는 고압이 형성되기 때문에 티타늄이나 스텐인레스스틸 등 강성이 확보되는 비자성 금속 재질을 사용한다. 또한, 상기 안내관(10) 내측으로 비나 눈 등 이물질이 유입되지 않게 뚜껑(13)을 제작하여 안내관(10) 상부에 탈부착되게 사용할 수 있다.The guide tube 10 is made of a non-magnetic material, but in the tank for storage of general oil, etc., pressure-resistant plastics and pressure-resistant glass are used, but since the inside of the high-pressure tank filled with liquefied gas forms high pressure, titanium or stainless steel is used. Use nonmagnetic metal such as steel to ensure rigidity. In addition, the lid 13 may be manufactured to be detachably attached to the upper portion of the guide tube 10 so that foreign substances such as rain or snow do not flow into the guide tube 10.
부자(30)는 상기 안내관(10)의 외주면 둘레에서 안내관(10)의 외주면과 접촉되지 않도록 일정 간극이 유지된 상태로 고리형태의 부자(30)를 설치하는데, 재질은 낮은 온도에서도 강성이 유지되도록 티타늄 또는 스테인레스스틸 등의 비자성재질로 제작한다.The rich man 30 installs the ring-shaped rich man 30 in a state where a predetermined gap is maintained so as not to contact the outer circumferential surface of the guide tube 10 around the outer circumferential surface of the guide tube 10, and the material is rigid even at a low temperature. It is made of a nonmagnetic material such as titanium or stainless steel to maintain this.
상기 부자(30)는 자성체(21)가 구비된 측정자(20)를 안내관(10)에 삽입시켜 부자(30)와 측정자(20) 사이에 형성되는 자력을 감지하여 액화가스의 액면을 측정하는데, 이와 같은 고압의 액화가스가 충진된 고압탱크(1)에 부자(30)를 적용하기 위해서는 다음과 같은 조건이어야 한다.The rich man 30 is inserted into the guide tube 10 with the magnetic body 21 is inserted into the guide tube 10 to detect the magnetic force formed between the rich man 30 and the meter 20 to measure the liquid level of the liquefied gas In order to apply the rich 30 to the high pressure tank (1) filled with such a high pressure liquefied gas, the following conditions should be applied.
첫째, 부자(30)는 고압탱크(1)에 충진된 액화가스 위로 부유되어야 하고,First, the rich man 30 should be suspended above the liquefied gas filled in the high pressure tank (1),
둘째, 사용자가 측정자(20)를 안내관(10)내에 삽입시켜 부자(30)의 위치를 감지하여 액면을 측정한 후 측정자(20)를 들어올릴 때, 부자(30)와 측정자(20) 사이에 형성된 자력에 의해 부자(30)가 끌려가지 않도록 적당한 무게를 가져야 하며,Second, when the user inserts the measurer 20 into the guide tube 10 to detect the position of the rich man 30 to measure the liquid level and then lift the measurer 20, between the rich man 30 and the measurer 20 It should have a proper weight so that the rich man 30 is not attracted by the magnetic force formed in the,
셋째, 부자(30)는 고압탱크(1)내의 한정된 공간에 설치되어야 한다.Third, the rich man 30 should be installed in a limited space in the high pressure tank (1).
고압탱크(1)의 크기와 사용되는 자성체(21)(31)의 자력에 따라 다소 가변적이지만 상기와 같은 조건을 만족시키기 위한 부자(30)의 일반적인 규격은 그 비중이 0.45~0.50(kg/㎥) 되고, 도우넛형으로 직경이 15cm 높이가 20cm 이며, 무게가 67.5~70.0g 이다.Although somewhat variable depending on the size of the high-pressure tank 1 and the magnetic force of the magnetic bodies 21 and 31 used, the general specification of the rich man 30 to satisfy the above conditions is 0.45 to 0.50 (kg / ㎥). It is donut-shaped, 15cm in diameter, 20cm in height, and weighs 67.5 ~ 70.0g.
또한, 고압탱크(1) 내에서 압괴현상이 일어나지 않도록 부자(30)의 내압강도를 25(kg/㎡) 이상이 되게 한다.In addition, the pressure-resistant strength of the rich (30) is 25 (kg / ㎡) or more so that the collapse does not occur in the high-pressure tank (1).
측정자(20)는 도3에 도시된 바와 같이 안내관(10) 내에서 용이하게 사용 및 수납되도록 줄자형태로 제작하되, 자성체(31)가 구비된 부자(30)와 상호 작용되도록 하단부에 자성체(21)가 구비되며, 상단부에 손잡이를 형성하며, 액면의 높이를 측정하도록 상기 손잡이와 자성체(21) 사이에 눈금을 형성한다.The measurer 20 is manufactured in a tape measure so as to be easily used and stored in the guide tube 10 as shown in FIG. 3, but has a magnetic material at the lower end so as to interact with the rich man 30 provided with the magnetic material 31. 21 is provided, a handle is formed at the upper end, and a scale is formed between the handle and the magnetic body 21 to measure the height of the liquid level.
상기 측정자(20)의 재질은 스테인레스스틸 등의 비자성 금속재질로 이루어진다.The measurer 20 is made of a nonmagnetic metal such as stainless steel.
일 실시예로서, 깊이가 5,000mm인 고압탱크(1)에 상기한 바와 같이 안내관(10)과 부자(30), 측정자(20)로 구성된 본 고안 액화가스용 수동감지 액면계를 설치한 것이다.As an embodiment, the high-pressure tank (1) having a depth of 5,000 mm is provided with a manual sensing liquid level meter for liquefied gas of the present invention composed of the guide tube 10, the rich man 30, and the measurer 20 as described above.
자성체(21)가 포함된 측정자(20)를 안내관(10) 안으로 삽입하면 측정자(20)의 하단부에 형성된 측정자(20)가 안내관(10) 바닥면에 닫게 된다. 이와 같은 상태에서 액면 높이를 측정하기 위하여 안내관(10) 하부로 내려진 줄자 타입의 측정자(20)를 올리면서 측정자(20)와 부자(30)에 각각 구비된 자성체(21)(31) 상호간 반발력 또는 인력이 작용되는 힘을 사용자가 감지함으로써 부자(30)의 위치를 파악하게 되고, 측정자(20) 상에 형성된 눈금을 육안으로 확인함으로써 고압탱크(1)내 액화가스의 액면을 측정할 수 있다.When the measurer 20 including the magnetic body 21 is inserted into the guide tube 10, the measurer 20 formed at the lower end of the measurer 20 is closed on the bottom surface of the guide tube 10. In this state, while raising the tape measure-type measuring instrument 20 lowered to the lower portion of the guide tube 10 in order to measure the liquid level, the magnetic bodies 21 and 31 respectively provided in the measurer 20 and the rich man 30 are mutually repulsive. Alternatively, the user grasps the position of the rich man 30 by sensing a force applied by the attraction force, and the liquid level of the liquefied gas in the high pressure tank 1 may be measured by visually checking the scale formed on the measurer 20. .
이상과 같은 본 고안의 효과는 다음과 같다.The effects of the present invention as described above are as follows.
부자의 비중이나 크기, 무게 등을 특정시켜 액화가스가 저장된 고압탱크나 탱크로리에 적용 가능한 수동감지 액면계를 제공하는 것으로,By specifying the specific gravity, size, weight, etc. of the rich, to provide a manual sensing liquid level meter that can be applied to the high pressure tank or tank lorry where liquefied gas is stored
고압탱크에 충진된 액화가스가 외부로 누출되지 않고 액화가스량을 안전하고 용이하게 측정할 수 있으며,It is possible to safely and easily measure the amount of liquefied gas without leaking the liquefied gas filled in the high pressure tank to the outside,
또한, 줄자 타입의 본 고안 측정자는 고압탱크 상방에 측정자를 위한 별도 공간이 필요치않고, 측정자의 중량이 가볍기 때문에 사용 편의성이 뛰어난 효과가 있다.In addition, the measuring device of the present invention of the tape measure type does not need a separate space for the measuring device above the high pressure tank, and because the weight of the measuring device is light, there is an excellent use convenience.
