Description
본 발명은 수도미터의 동파를 방지하기 위한 것으로서, 수도미터와 그 주변부속의 보온방법에 관한 것이다.The present invention is to prevent the freezing of the water meter, and relates to a method of keeping the water meter and its surrounding parts.
지난 겨울(2000년 12월부터 2001년 2월까지)의 혹한에 국내 수도미터는 사상유래가 없는 동결및 동파의 수난을 당하였다 특히 기온이 낮은 한강 이북지역과 수도권의 피해가 막대하였다. 동파를 겪은 시민의 불편은 물론이려니와 복구공사와 비용 또한 막대하였다. 지난 겨울 이후 본 발명에 대한 필요가 절실해 진 것이다. 종래에도 수도미터와 그 주변의 보온을 위하여 여러형태의 방법이 강구되어 왔다 전열선 또는 반 도전성 발열체로 이루어진 정온전선를 수도미터에 직선이나 또 나선형으로 감아 발열시켜 보온하는 방법을 많이 사용하였다. 도1은 정온전선을 연질의 보온커버에 내장시킨(출원번호20-1998-0008855호)것이고, 도2는 전열선을 보온커버안에 구성한(실용신안등록20-2000-0192013호)것이다.In the cold of winter last year (December 2000 to February 2001), domestic water meters suffered freezing and freezing of floods, which were unprecedented in history. As well as the inconvenience of the citizens who suffered freezing, the restoration work and costs were enormous. Since last winter, the need for the present invention is urgent. Conventionally, various types of methods have been devised for the insulation of the water meter and its surroundings. There have been many methods of heating a constant temperature wire made of a heating wire or a semi-conductive heating element by heating it linearly or spirally with a water meter to generate heat. 1 shows a constant temperature wire embedded in a soft insulating cover (Application No. 20-1998-0008855), and FIG. 2 shows a heating wire formed in a thermal cover (Utility Model Registration 20-2000-0192013).
상기 종래의 구조들은 수도미터 형상에 맞춰 조립될 수 있도록 하고 전기발열선을 사용한다. 보온커버의 내부에 보온재가 구성되고 보온재의 위에 열선이 배치되고 소정의 온도가 설정된 온도센서가 구비되어 설정온도 이하에서 온도를 감지하면 작동하여 열선에 전원이 인가되고 발열한다. 일정한 시간이 경과된 후 소정의 온도로 가온되면 온도센서가 역시 감지하고 전원을 단락한다. 이러한 동작이 반복되어 발열에 의한 보온방식으로 동결및 동파를 예방하게 된다.The conventional structures can be assembled to the shape of a water meter and use an electric heating wire. Insulating material is configured inside the insulating cover, and a heating wire is disposed on the insulating material, and a temperature sensor having a predetermined temperature is provided to operate when the temperature is sensed below the set temperature to supply power to the heating wire and generate heat. After a certain time has elapsed, if the temperature is warmed to a predetermined temperature, the temperature sensor also detects and shorts the power supply. This operation is repeated to prevent freezing and freezing by the heat insulation method by heat generation.
그러나 상기와 같은 종래의 발열보온커버의 내부에 구비한 보온재가 연질이기는 하나 수도미터와 부품을 감쌀 때 잘 휘어지지 않으므로 1cm안팎의 얇은 것이 사용되고 있고 이는 단열효과가 떨어져 부득히 발열온도를 높여야 하는 단점이 있어왔다.However, since the thermal insulation material provided in the inside of the conventional thermal insulation cover as described above is soft but does not bend when wrapping the water meter and the components, a thin one of about 1 cm is used, which is disadvantageous in that the heat generation temperature is inevitably lowered due to the poor insulation effect. Has been.
또 겨울철에 설치하여 사용중일지라도 전원이 인가된 상태인지 아닌지 확인이 않되고, 혹 열선이 단락된 경우에 확인할 수 없으므로 방치하여 동파를 겪을 우려가 있다.In addition, even if it is installed and used in the winter, it is not checked whether the power is on or not, and if the heating wire is short-circuited, it may not be confirmed and there is a fear of freezing.
특히 월동전 점검할 필요가 있으나 가을의 기온이 온도센서에 설정된 온도보다 높아 온도센서가 작동하지 않으므로 점검할 수 없어 열선이 단락된 경우에도 알지 못하므로 그대로 사용(방치)하여 동파가 발생한 후에야 알게 되는 경우가 발생되고 있는 실정이다.In particular, it is necessary to check before wintering, but because the temperature in autumn is higher than the temperature set in the temperature sensor, the temperature sensor does not work. Cases are occurring.

상기의 목적을 달성하기 위한 본 발명은 수도미터와, 수도미터의 부품들( 입수관쪽 커넥션튜브와 너트, 출수관쪽 커넥션튜브와 너트, 엘보, 앵글밸브)를 한꺼번에 감쌀 수 있는 수도미터의 보온커버는;In order to achieve the above object, the present invention provides a water meter and a water meter insulation cover which can cover parts of the water meter (inlet tube side connection tube and nut, outlet tube side connection tube and nut, elbow, angle valve) at once. ;
커버부(도 5의 24)내의 보온재의 유연함을 위하여, 즉 수도미터와 부품들을 보온커버로 감쌀때 발생되는 보온재의 변형(strain)에서 수반되는 응력(stress)을 줄이는 방법으로 도3과 같이 보온재의 양면에 바둑판과 같이 칼집을 내어 절개부(37)를 형성한다. 도4에서와 같이 양면의 절개부'37'에 부품이 닿게 된다고 가정하면 부품이 닿는'37'의 반대편 절개부위'37a'가 각각 팽창하여 V자형으로 골이 생기며 응력을 흡수하므로 휘어짐이 좋아 부품의 형상에 밀착하여 설치하기가 용이한 것이다.Insulating material as shown in Figure 3 in order to reduce the stress (stress) in the strain of the thermal insulation material generated when the cover of the insulation (24 24 of Figure 5), that is, when the water meter and parts wrapped with the insulation cover Cut the sheath like a checkerboard on both sides of the incision to form 37. Assuming that the parts are in contact with the incision '37' on both sides as shown in Figure 4, the incisions '37a' opposite the '37' on which the parts touch each other are expanded to create a valley in the V-shape and absorb the stress, so the parts are well bent It is easy to install close to the shape of.
상기의 보온재위에 열에 강하고 또 절연성이 있는 단열재(22)를 덮고 그 위에 열선(20)이 배치된다.The heat wire 20 is disposed on the heat insulating material and covers the heat-insulating material 22 that is strong and insulating.
열선은 1.5∼2.0cm정도의 간격을 유지함이 적당하고 얇은 알미늄테잎(21)을 사용 접착하여 배치함이 바람직하다. 그것은 열 전도율이 높고 금속성으로 열에 강하기 때문이다. 열선(20)의 한쪽 끝은 전원(18)에 단자(Terminal)로 연결되고 다른 한 쪽은 전원표시램프(31), 발열표시램프(32), 점검스위치(33), 온도센서(25)와 온도휴즈(27)가 연결된다.The hot wire is suitable to maintain the interval of about 1.5 ~ 2.0cm, it is preferable to arrange by bonding using a thin aluminum tape 21. It is because of its high thermal conductivity and being metallic and resistant to heat. One end of the heating wire 20 is connected to the power supply 18 by a terminal, and the other end of the heating wire 20 is connected to the power supply lamp 31, the heating display lamp 32, the check switch 33, and the temperature sensor 25. The temperature fuse 27 is connected.
설치작업이 쉽도록 도6과 같이 매직테잎(28)이 구성되어 착탈이 용이하도록한다.The magic tape 28 is configured as shown in Figure 6 to facilitate the installation work to facilitate the removal.
전원(18)이 인가되면 전원표시램프(31)가 점등되고 소정의 온도가 설정된 온도센서(25)의 온도에 도달하면 감지되어 열선(20)에 전원이 인가되고 발열한다. 발열하면 발열표시램프(32)가 점등한다. 발열은 설치환경에 따라 다르지만 상당 시간 지속되며 보온상태를 유지한다. 발열상태가 긴 것은 낮은 미열을 발생하기 때문이다(수도미터의 내부에는 기차가 회전할때 그 회전을 숫자로 바꾸기 위하여 많은 기어를 사용하는데 이 기어의 사용온도가 30℃이하에서 사용하는 조건으로 생산되기 때문에 그 이상의 온도에서 사용될 때 변형될 염려가 있다. 해마다 상당량의 수도미터가 각종 발열히터, 정온전선에 의하여 화상을 입고 있는 실정이다).When the power source 18 is applied, the power display lamp 31 is turned on, and when a predetermined temperature reaches the temperature of the set temperature sensor 25, the power source 18 is detected and power is applied to the heating wire 20 to generate heat. When the heat is generated, the heat generation display lamp 32 lights up. The heat generation depends on the installation environment, but it lasts for a long time and keeps warm. Long heat generation is caused by low low heat (many gears are used inside the water meter to convert the rotation to a number when the train is rotating. When used at a higher temperature, there is a risk of deformity, and a considerable amount of water meters are burned each year by various heating heaters and constant temperature wires.
일정시간이 경과하면 온도가 상승하고 이 상승된 온도가 온도센서(25)의 설정된 온도보다 높아지면 온도센서가 다시 감지하여 인가된 전원은 단락되고 열선의 발열은 중단되며 발열표시램프(32)는 소등된다.When a certain time elapses, the temperature rises, and when the elevated temperature rises above the set temperature of the temperature sensor 25, the temperature sensor detects again, the applied power is short-circuited, the heating of the hot wire is stopped, and the heating display lamp 32 It goes out.
상기와 같은 발열및 단락이 지속적으로 반복되어 보온이 유지된다.The above heat generation and short circuit are continuously repeated to maintain warmth.
가을 또는 초 겨울 월동을 위한 점검을 위하여 점검스위치(33)를 접속하면 온도센서(25)를 경유하지 않고 직접 열선에 전원이 인가되므로 발열되고 발열표시램프(32)가 점등한다.When the check switch 33 is connected to check for fall or early winter winter, the power is directly applied to the heating wire without passing through the temperature sensor 25 so that the heat generation lamp 32 is turned on.
그러나 전원램프(31)는 점등되고 발열표시램프(32)가 점등되지 않는다면 열선(20)이 단락되었거나 또 다른 이상이 있음을 발견할 수 있는 것이다.However, if the power lamp 31 is turned on and the heating display lamp 32 is not lit, it may be found that the heating wire 20 is shorted or there is another abnormality.
상기와 같은 구조에도 불구하고 예견하지 못한 불가항력의 사태에 의하여 과열이 발생될 경우를 대비하여 소정의 온도가 설정된 온도휴즈(27)를 구비하였다.Despite the structure as described above, a temperature fuse 27 having a predetermined temperature is provided in case of overheating due to an unexpected force majeure.
상기와 같이 매직테잎방식을 적용하여서 설치가 단순하여 관련분야의 기술이나 경험이 없이도 쉽고 빠르게 부착 설치할 수 있는 보온커버는;By applying the magic tape method as described above, the installation cover is simple and easy to install quickly and easily installed without the related art or technology;
1.수도미터와 부품들을 보온커버로 감쌀때 발생되는 보온재의 변형에서 수반되는 응력를 절개부가 흡수하므로 두꺼운 보온재를 부품의 형상에 밀착하기가 유연한 특징이 있다.1. The insulator absorbs the stresses caused by the deformation of the insulation, which occurs when the water meter and the components are covered with the insulation cover, so it is flexible to closely adhere the shape of the thick insulation.
2.전원을 인가하면 전원표시램프(31)가 점등하고, 설정된 온도에 도달하면 온도센서(25)가 감지하여 열선(20)이 발열하면 발열표시램프(32)가 점등된다. 적당히 따뜻해지면 온도센서가 상승한 온도를 감지하여 전원을 단락시키므로 발열이 중단되고 발열표시램프가 꺼진다.2. When the power is applied, the power display lamp 31 lights up, and when the temperature reaches the set temperature, the temperature sensor 25 senses and the heating wire 20 generates heat, and the heating display lamp 32 lights up. If it gets warm enough, the temperature sensor senses the temperature and short-circuits the power supply so that the heat generation is stopped and the heat indication lamp is turned off.
상기와 같은 동작이 반복적으로 수행되어 수도미터가 얼거나 동파되는 것을 방지하게 된다.The above operation is repeatedly performed to prevent the water meter from freezing or freezing.
3.계절(기온)에 관계없이 점검스위치(33)를 접속하면 온도센서와 관계없이 열선(20)에 전원이 인가되므로 발열과 동시에 발열표시램프가 점등하므로 정상임을 확인할 수 있다.3. Regardless of the season (temperature), if the check switch 33 is connected, the power is applied to the heating wire 20 irrespective of the temperature sensor, so that the heating display lamp lights up at the same time as the heating, thereby confirming normal operation.
상기와 같이 확인과 점검에도 불구하고 불가항력의 사고에 의한 과열이 발생할 가능성에 대비하여 소정의 온도를 설정한 온도휴즈(27)를 구성하였으므로 화재의 우려가 있는 정도로 과열되면 온도휴즈는 단락되어 전원이 차단되는 안전한 특징이 있다.Despite the check and inspection as described above, the temperature fuse 27 is set to a predetermined temperature in preparation for the possibility of overheating due to an accident of force majeure. There is a safe feature that is cut off.
