Abstract
본 건은 가정용 수도미터기에서 시동유량(기동:감도)을 향상시키는데 획기적인 항목으로 시동유량이란 수도미터기가 작동할 수 있는 유량을 말한다.This is a breakthrough item to improve the starting flow rate (start: sensitivity) in domestic water meters. Starting flow rate refers to the flow rate at which the water meter can operate.
시동 유량을 향상시키기 위해 많은 방법이 강구되었으나 현재까지 획기적인방안은 없었으며 본 건으로 인하여 계량기의 성능 개선이 가능하게 되었으며 향후 계량기 불감수량을 향상시키 수도요금 산정에 상당한 기여를 하며 아울러 건물 배관중 누수나 위생설비등 수도꼭지 고장으로 인한 누수까지도 감지가 가능하여 누수로 인한 대형사고를 초기예방에도 기여할 수 있는 획기적인 장치임.Many methods have been taken to improve the starting flow rate, but there have been no significant measures up to now, and this has made it possible to improve the performance of the meter. It is a groundbreaking device that can detect leaks caused by failures of faucets, such as sanitary facilities, and contribute to the initial prevention of large accidents caused by leaks.
본 고안의 간단한 설명은 다음과 같다.Brief description of the present invention is as follows.
"제2도"와 같이 익차의 중심부(사파이어 삽입부)에 빈 공간을 활용하여 부상물질을 충진하고 익차무게와 물의 비중이 1:1로 유지되게 하여 수중에서 무중력 상태를 유지하게하거나 제3도와 같이 계량기 상부 또는 하부에 자석을 이용 자기 부상시켜 최소의 유속에서 수도미터기가 저항 없이 작동 가능하게 하는 장치임(즉 우주인이 무중력 상태에서 자연스럽게 유영하는 형태를 수도계량기에 적용시킴)As shown in Fig. 2, the empty space is used in the center of the van (sapphire insert) to fill the floating material and to maintain the weightlessness of the vanilla and water at 1: 1 so that the weightlessness is maintained in the water. Similarly, a device that floats magnetically on the upper or lower part of the meter so that the water meter can operate without resistance at the minimum flow rate (ie, the astronaut applies a naturally flowing form to the water meter in a zero gravity state).
아울러, 현재 날개단면이 직사각형으로 형성되어 회전저항이 작용하여 감도가 떨어지는 요인으로 날개 단면을 유선형으로 개량하여 회전저항이 감소되게 하여 감도를 향상시켜 초정밀 수도계량기 개발이 가능케 함으로 전국적인 수도사업 경영에 획기적으로 기여할 것으로 기대됨.In addition, the wing section is formed in a rectangular shape, and the rolling resistance acts to reduce the sensitivity, and the blade section is improved to a streamlined shape, which reduces the rolling resistance, thereby improving the sensitivity, enabling the development of ultra-precision water meter. It is expected to contribute significantly.
Description
본 건으로 가정용 수도시설에 핵심이 되는 수도미터기 내부에 설치된 회전익차로서 종전의 경우 엔지니어링 프라스틱, 아세탈 ABS 등 합성수지로 사출성형 가공하여 사용하고 있으나, 익차의 무게를 경량화 하는데 한계가 있어 수도미터기가 작동할 수 있는 시동유량이 커서 작은 유량에서는 계량기가 감지할 수 없어 수돗물을 공급하고서도 수도요금을 받지 못하는 현상즉 무수율이 전국적으로 많이 발생하여 정수장, 급·배수관등 상수도 시설의 투자비를 증가시키고, 실제 이용율은 저하되어 수도요금인상과 수도사업경영에 많은 문제점이 대두되고 있음In this case, the rotor blades installed inside the water meter, which is the core of domestic water facilities, have been used by injection molding processing with synthetic resin such as engineering plastics and acetal ABS. It is a phenomenon that the meter cannot detect water at a small flow rate because the starting flow rate is large, so that the water rate is not received even though the tap water is supplied. Has been declining, causing many problems in water rate hikes and water business management.
본 건은 상기와 같은 문제점을 해소하기 위해 계량기를 작동시키는 회전익차를 수중에서 무중력상태를 유지하기 위해 익차중심부(사파이어 삽입부)에 빈 공간을 활용하여 부상물질을 충진하고 익차무게와 물의 비중이 1:1로 유지되게 하거나 계량기 익차 상부 또는 하부에 자석을 이용 자기부상시켜 최소의 유속에서도 수도미터기가 저항없이 작동이 가능하게하는 장치임.(즉 우주인이 무중력 상태에서 자연스럽게 유영하는 형태를 계량기에 적용시킴) 아울러 현재 날개단면을 유선형으로 개량하여 회전저항이 감소되게하여 감도를 향상시켜 초정밀 수도계량기를 개발하고자 함.In this case, in order to solve the above problems, in order to maintain the weightlessness of the rotorcraft which operates the meter, the empty space is filled in the center of the wing (sapphire insert) to fill the floating material and the weight of the wing and water It is a device that maintains 1: 1 or uses a magnet on the upper or lower part of the meter wing to allow the water meter to operate without resistance even at the minimum flow rate (that is, the astronaut is naturally flowing in the zero gravity state. In addition, the wing section is now streamlined to improve the sensitivity by reducing the rolling resistance to develop an ultra-precision water meter.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
"도2"은 초정밀 수도미터용 무중력 익차로서 익차중심부에 빈 공간을 활용하여 부상물질을 충진하여 익차무게와 물의비중이 1:1이 되도록 하고 익차단면을 유선형으로 개량하여 회전저항없이 계량이 가능토록 제작하고,"Figure 2" is a gravity-free van for high-precision water meter, fills floating material by using empty space in the center of the van, so that the ratio of vane weight and water is 1: 1 and improves the vane section in streamline to measure without rotational resistance. To make it possible,
"도3"은 익차를 자기 부상시켜 상기와 같은 효과를 얻어 계량기 감도를 향상시키고자 함.3 is intended to improve the sensitivity of the meter by magnetically floating the wing car to obtain the same effect as above.
이상에서 기술한바 와 같이 본 건은 수도계량기 익차를 부상시켜 아주 적은 유량에서도 계량기가 작동하므로 계량기 감도를 향상시켜 초정밀 수도계량기 개발이 가능하고 전국적으로 수도사업경영에 획기적으로 기여할 것으로 기대됨.As described above, this case raises the water metering van and makes the meter operate at very low flow rate, so it is possible to develop ultra-precision water meter by improving the sensitivity of the meter and to contribute to the water business management nationwide.
