본 발명은 보급수를 이용한 압력불변식 밀폐형 팽창탱크에 관한 것으로, 건축물의 냉난방 설비 및 유체의 온도 변화가 수반되는 밀폐배관에서 유체의 온도변화에 따른 유체팽창을 흡수할 수 있도록 한 보급수를 이용한 압력불변식 밀폐형 팽창탱크에 관한 것이다.The present invention relates to a pressure-invariant hermetic expansion tank using replenishment water, using a replenishment water to absorb fluid expansion due to a change in temperature of a fluid in a closed pipe accompanied by a temperature change of a building's heating and cooling facility and a fluid. A pressure invariant closed type expansion tank.
일반적으로 건축물의 냉난방 설비 및 유체의 온도변화가 수반되는 밀폐배관에 연결 설치되어 유체의 온도변화에 따른 유체팽창을 흡수하기 위하여 제4도에 도시된 바와 같은 팽창탱크 내부에 압력실을 구분하는 다이어프램(격막)이 내장되고 냉난방 설비 및 유체의 온도변화가 수반되는 밀폐 배관의 압력과 동일한 압력의 압축공기가 상기 팽창탱크 내부 일측의 압력실에 봉입된 팽창탱크로 밀폐 배관설비에 연결 설치하고 밀폐배관 내부의 온도 변화에 따라 팽창되는 유체는 다이어프램으로 구분된 밀폐탱크의 압력실에 초기압력으로 봉입된 공기를 압축하며 팽창되어 밀폐배관의 팽창력을 흡수하도록 함으로서 온도상승에 따른 유체팽창으로 과다하게 압력이 상승된 밀폐배관의 누수 및 파손을 방지하도록 하였다.In general, a diaphragm for dividing the pressure chamber inside the expansion tank as shown in FIG. 4 in order to absorb the fluid expansion according to the temperature change of the fluid by being installed in the air-conditioning facility of the building and the sealed pipe accompanying the temperature change of the fluid. The compressed air of the same pressure as the pressure of the sealed pipe with the built-in diaphragm and accompanying the temperature change of the air-conditioning equipment and the fluid is connected to the expansion pipe sealed by the expansion tank enclosed in the pressure chamber on one side of the expansion tank and the sealed pipe The fluid that expands according to the temperature change inside compresses the air enclosed with the initial pressure in the pressure chamber of the diaphragm sealed tank and expands to absorb the expansion force of the sealed pipe. It is to prevent leakage and breakage of the raised sealed pipe.
또한, 개방형 배관의 경우 유체팽창의 팽창력을 흡수하기 위하여 배관의 일부가 대기 중에 노출되도록 하여 온도변화에 따른 유체의 팽창시 유체가 노출된 부분을 통하여 팽창되는 유체의 팽창력을 흡수하도록 하였으나, 이는 밀폐배관의 특성인 배관내부에 공기가 유입되어 유체에 공기속의 산소가 용해됨으로서 공기중의 산소로 인한 산화작용으로 배관 내부에 부식이 발생되어 배관의 수명을 단축하며 배관을 통하여 흐르는 유체의 청결성을 유지하기가 곤란하였다.In addition, in the case of an open pipe, part of the pipe is exposed to the atmosphere in order to absorb the expansion force of the fluid expansion, so that the expansion force of the fluid that is expanded through the exposed part of the fluid when the fluid is expanded due to the temperature change is absorbed. Air flows into the pipe, which is the characteristic of the pipe, and oxygen in the air dissolves in the fluid, which causes corrosion inside the pipe due to oxidation caused by oxygen in the air, reducing the life of the pipe and maintaining the cleanliness of the fluid flowing through the pipe. It was difficult to do it.
따라서, 전술한 밀폐배관의 팽창력을 흡수하기 위한 팽창탱크를 건축물의 일정 위치에 설치하여 건축물의 온도변화가 수반되는 밀폐배관에 설치하여 사용하였다.Therefore, an expansion tank for absorbing the expansion force of the hermetic pipe was installed at a predetermined position of the building, and used to install in the hermetic pipe accompanying the temperature change of the building.
그러나 상기의 팽창탱크는 건축물에 따른 밀폐배관의 규모에 따라 변화되는 유체압력을 감안하여 팽창탱크의 다이어프램(격막)으로 구분되는 일측의 압력실에 봉입되는 공기의 압력을 조정하여 설치하여야 했으며, 온도변화에 따른 유체의 팽창력으로 밀폐배관내의 압력이 상승됨에 따라 배관 및 그에 따른 장비의 설계시 유체의 압력상승 만큼의 여유를 두도록 선정하여야 하였다.However, the expansion tank should be installed by adjusting the pressure of the air enclosed in the pressure chamber of one side divided into the diaphragm (diaphragm) of the expansion tank in consideration of the fluid pressure changes according to the size of the sealed pipe according to the building, the temperature As the pressure in the closed pipe is increased due to the expansion force of the fluid, it was selected to allow the pressure increase of the fluid in the design of the pipe and its equipment.
또한, 팽창탱크의 압력실에 봉입되는 공기의 압력이 각 배관시스템의 수직높이에 따른 압력이나 배관을 통하여 보급되는 보급유체의 압력보다 작을 경우에는 팽창탱크의 용량 부족으로 배관계통의 압력상승폭이 설계값보다 크게 나타난 배관설비의 유지보수에 어려움이 발생되었으며, 압력실에 봉입되는 공기의 압력이 과다할 경우에는 배관설비의 사용압력의 초과로 인한 배관의 누수 및 파손을 가져왔다.In addition, if the pressure of the air enclosed in the pressure chamber of the expansion tank is less than the pressure according to the vertical height of each piping system or the pressure of the supply fluid supplied through the piping, the pressure increase width of the piping system is designed due to the lack of capacity of the expansion tank. Difficulties occurred in the maintenance of the piping equipment, which was larger than the value. When the pressure of the air enclosed in the pressure chamber was excessive, leakage and damage of the piping were caused by the excess of the operating pressure of the piping equipment.
이에 따라 팽창탱크의 압력실에 봉입되는 공기의 압력을 각 배관시스템의 수직높이에 따른 압력이나 각배관을 통하여 공급되는 보급 유체의 압력과 동일한 압력으로 봉입하여야 하는 문제점이 제기되었다.Accordingly, there is a problem that the pressure of the air enclosed in the pressure chamber of the expansion tank should be sealed at the same pressure as the vertical height of each piping system or the pressure of the supply fluid supplied through each pipe.
아울러 같은 규모의 배관시스템의 경우에도 상기 팽창탱크의 설치 위치인, 즉 설치되는 높낮이에 따라 배관의 수직높이에 따른 압력의 변수인 유효용량계수의 값이 10배 이상의 차이가 발생됨에 따라 팽창탱크의 용량(팽창량÷유효용량계수)도 상당한 차이가 발생하였으며, 이에 따라 팽창탱크의 설치장소 선정에 주의하여야 하는 번거로움이 제기되었으며, 팽창탱크의 압력실이 정해진 초기의 압력으로 봉입된 공기가 누출되었을 경우에는 팽창탱크의 역할을 하지 못하고 배관내의 유체가 유입되어 유체저장탱크로 변해버려 유체의 온도변화에 따른 팽창시 배관내의 유체압력을 흡수할 수 없으므로 압력이 무제한으로 상승되어 배관 및 장비의 파손을 수반하게 되어 막대한 재산상의 손실을 동반하였으며, 이에 따라 팽창탱크 압력실의 압력을 정기적으로 점검하여 압력저하에 따른 공기 주입작업을 하여야 하는 유지보수에 어려운 문제점이 제기되었다.In addition, in the case of piping systems of the same size, the expansion tank of the expansion tank has a difference in the effective capacity coefficient, which is a variable of pressure depending on the vertical height of the pipe, according to the installation position of the expansion tank. Significant differences also occurred in capacity (expansion amount ÷ effective capacity coefficient), which caused trouble to be careful in selecting the installation location of the expansion tank, and leaked air sealed at the initial pressure of the expansion tank pressure chamber. In this case, the fluid does not act as an expansion tank and the fluid in the pipe flows into a fluid storage tank, so the fluid pressure in the pipe cannot be absorbed during expansion due to the temperature change of the fluid. This entailed enormous property loss, which caused the pressure in the expansion tank pressure chamber to The problem of maintenance that requires air injection work due to pressure drop has been raised.
따라서 본 발명은 상기와 같은 문제점을 해소하며 팽창탱크와 배관의 설계가 용이하고 유체의 팽창이 발생시 배관시스템의 압력변동이 발생하지 않고 팽창탱크의 용량을 작게 설계하여 제작비용의 감소를 가져올 수 있도록 하며, 유지관리가 용이하도록 한 보급수를 이용한 압력불변식 밀폐형 팽창탱크를 제공하는데 본 발명의 목적이 있다.Therefore, the present invention solves the above problems, and it is easy to design expansion tanks and pipes, and when the expansion of fluid occurs, the pressure of the piping system does not occur, so that the capacity of the expansion tank can be designed to reduce the production cost so that it can be reduced. And, it is an object of the present invention to provide a pressure-invariant hermetic expansion tank using replenishment water to facilitate maintenance.
상기와 같은 본 발명의 목적을 달성하기 위하여 공급되는 유체의 흐름을 단속하는 역지변이 구비된 유체보급밸브와 배관계통의 유체의 공급과 역류를 방지하는 역지밸브와 배출밸브의 이상에 따라 동작되는 안전밸브를 주머니형 격막이 내부에 설치된 팽창탱크에 구비하여 배관설비에 설치하므로서 상술한 소기의 목적을 달성할 수 있다.In order to achieve the object of the present invention as described above is operated in accordance with the abnormality of the check valve and the discharge valve to prevent the supply and backflow of the fluid supply valve and the fluid supply valve having a reverse flow to interrupt the flow of the supplied fluid By providing the safety valve in the expansion tank installed inside the bag-shaped diaphragm to be installed in the piping facility can achieve the above-mentioned object.

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
밀폐탱크(1) 내부에 삽입, 설치되는 격막(4)은 상측의 밸브본체(10)와 밀폐탱크(1)의 결합과 동시에 결합되게 하여 밸브본체(10)과 밀폐탱크(1)와의 기밀을 유지하도록 하며, 상기 밀폐탱크(1) 상측에 설치되는 밸브본체(10)는 상측의 연결부(11)에 유체공급관(P)을 연결하며, 상기 유체공급관(P)에서 공급되는 유체가 공급밸브(12)를 통하여 밀폐탱크(1)의 주머니형상의 격막(4)에 채워지도록 하였다.The diaphragm 4 inserted and installed in the sealed tank 1 is coupled to the upper side of the valve body 10 and the sealed tank 1 at the same time so that the airtightness between the valve body 10 and the closed tank 1 is secured. The valve body 10 installed above the sealed tank 1 connects the fluid supply pipe P to the upper connection part 11, and the fluid supplied from the fluid supply pipe P is supplied to the valve body 10. 12) to fill the pocket-shaped diaphragm 4 of the closed tank (1).

이때, 밀폐탱크(1)의 격막(4) 내부의 압력이 일정압력 이상으로 되면 그 압력으로 탄성 스프링(21)을 압축하게 되는 것으로, 밸브본체(10)의 배출밸브(13)의 이상이 발생되어 격막(4)내부의 압력과 유체공급관(P)의 압력이 동일하지 않을 경우에만 격막(4)내의 유체가 배출되어 과압된 밀폐배관설비(S)의 압력이 강하되도록 한 것이다.At this time, when the pressure inside the diaphragm 4 of the closed tank 1 becomes a predetermined pressure or more, the elastic spring 21 is compressed by the pressure, and an abnormality of the discharge valve 13 of the valve body 10 occurs. Only when the pressure in the diaphragm 4 and the pressure of the fluid supply pipe (P) is not the same, the fluid in the diaphragm (4) is discharged so that the pressure of the overpressured closed piping facility (S) is lowered.
이와 같이 된 본 발명의 동작 관계를 설명하면 다음과 같다.Referring to the operation relationship of the present invention as described above is as follows.
유체공급관(P)을 통하여 공급되는 유체는 밸브본체(10)의 공급밸브(12)를 통하여 밀폐탱크(1)내의 격막(4)에 채워지며 상기 격막(4)내에 채워진 유체는 역지밸브(15)를 통하여 밀폐배관설비(S)의 각 라인으로 공급되며 밀폐탱크(1) 하측의 연결부(3)에 밀폐배관 설비(S)의 일측 라인을 연결하여 유체의 압력이 전달되도록 하였다.The fluid supplied through the fluid supply pipe P is filled in the diaphragm 4 in the closed tank 1 through the supply valve 12 of the valve body 10, and the fluid filled in the diaphragm 4 is a check valve 15. It is supplied to each line of the hermetic piping facility (S) through a) and connected to one side line of the hermetic piping facility (S) to the connection portion 3 of the lower side of the hermetic tank (1) to transmit the pressure of the fluid.
따라서, 밀폐배관설비(S)내에 채워진 유체가 보일러 등 기타 열원장비에 의해 온도가 상승되면 대기와의 개방된 부분이 없는 밀폐식 배관이므로 밀폐배관설비(S)내의 유체가 팽창되어 증가된 압력에 의해 유체는 팽창탱크(1)의 하측에 구비된 연결관(3)을 통해 주머니형상의 격막(4)의 외측에서 압력을 가하며 팽창탱크(1) 내부로 유입된다.Therefore, when the fluid filled in the sealed piping facility (S) is raised by the heat source equipment such as a boiler, the sealed pipe without the open part with the atmosphere is expanded, so the fluid in the sealed piping facility (S) is expanded to increase the pressure. As a result, the fluid is introduced into the expansion tank 1 by applying pressure from the outside of the bag-shaped diaphragm 4 through the connection pipe 3 provided under the expansion tank 1.
상기 팽창탱크(1)의 내부로 유입된 유체는 압력이 증가된 만큼 격막(4)을 압축하며, 이때 압력이 증가되는 격막(4) 내부의 유체는 배출 밸브(13)를 통하여 유체공급관(P)으로 역류되게 된다.The fluid introduced into the expansion tank 1 compresses the diaphragm 4 as the pressure is increased, and the fluid inside the diaphragm 4 where the pressure is increased is connected to the fluid supply pipe P through the discharge valve 13. Back).
즉, 상기 밸브본체(10) 일측의 밀폐배관설비(S)로 연결되는 역지밸브(15)는 밀폐배관설비(S)내의 증가된 유체의 압력이 격막(4)내 유체의 압력과 동일하게 유체가 상기 밀폐배관설비(S)로의 공급이 제한된다.That is, the check valve 15 connected to the sealed piping facility (S) on one side of the valve body 10 has the same fluid pressure as that of the fluid in the diaphragm (4). The supply to the hermetic piping facility (S) is limited.
따라서 격막(4)내 압력 상승으로 인한 유체가 배출밸브(13)를 통하여 배출되어 밀폐배관설비(S)의 증가된 압력을 흡수하도록 하였으며, 밀폐배관설비(S)의 온도가 하강되면 유체의 팽창력이 감소되어 유체의 압력이 낮아지게 되며, 유체공급관(P)의 압력보다 낮아지게 되면 공급밸브(12)를 통하여 격막(4)내로 유체가 다시 공급되어 유체공급관(P)의 압력과 밀폐탱크(1)내에 격막(4)에 채워진 유체의 압력과 밀폐배관설비(S)의 유체압력이 동일한 상태가 유지되는 것이다.Therefore, the fluid due to the pressure rise in the diaphragm 4 is discharged through the discharge valve 13 to absorb the increased pressure of the sealed piping facility (S), and when the temperature of the sealed piping facility (S) is lowered, the expansion force of the fluid When the pressure of the fluid is reduced and the pressure of the fluid supply pipe (P) is lowered, the fluid is supplied back into the diaphragm (4) through the supply valve 12, the pressure of the fluid supply pipe (P) and the closed tank ( 1) The pressure of the fluid filled in the diaphragm 4 and the fluid pressure of the hermetic piping installation S are maintained.
한편, 안전밸브(20)는 밀폐배관설비(S)내의 유체가 팽창되어 밀폐탱크(1)내로 유입되는 유체가 격막(4)을 압축하여 격막(4)에 채워진 유체의 배출이 배출밸브(13)를 통하여 원활히 이루어지면서 동작되지 않는 것으로, 상기 뱅출밸브(13)의 이상이나 유체공급관(P)의 이상이 발생되어 배출밸브(13)가 동작되지 않으면 격막(4)내의 압력은 무한대로 증가되며, 따라서 밀폐배관설비(S)의 압력도 증가되어 설비의 파손을 방지하기 위한 것으로 격막(4)내의 압력이 유체공급관(P)의 압력보다 높은 일정압력으로 상승되면 유체는 탄성스프링(21)을 밀며 안전밸브(20)를 개방하여 배출구(22)를 통하여 유체가 대기중으로 방출되도록 하므로서 격막(4)내의 이상압력이 해소되도록 하였다.On the other hand, the safety valve 20 is the fluid in the hermetic piping facility (S) is expanded and the fluid flowing into the hermetic tank (1) compresses the diaphragm (4) to discharge the fluid filled in the diaphragm (4) discharge valve (13) If the discharge valve 13 is not operated because of an abnormality of the outlet valve 13 or an abnormality of the fluid supply pipe P, the pressure in the diaphragm 4 is increased to infinity. Therefore, the pressure of the sealed piping system (S) is also increased to prevent damage to the equipment. When the pressure in the diaphragm (4) is raised to a constant pressure higher than the pressure of the fluid supply pipe (P), the fluid opens the elastic spring (21). By pushing and opening the safety valve 20 so that the fluid is discharged into the atmosphere through the outlet 22, the abnormal pressure in the diaphragm 4 is to be eliminated.

(4) the fluid due to the increase in pressure is discharged through the discharge valve (13) to absorb the increased pressure of the sealed piping facility (S), and the expansion force of the fluid decreases when the temperature of the sealed piping facility (S) is lowered The pressure of the fluid is lowered, and when the pressure is lower than the pressure of the fluid supply pipe P, the fluid is supplied again into the diaphragm 4 through the supply valve 12. The pressure of the fluid supply pipe (P) and the pressure of the fluid filled in the diaphragm (4) of the closed tank (1) and the fluid pressure of the sealed piping facility (S) is maintained the same state.
한편, 안전밸브(20)는 밀폐배관설비(S)내의 유체가 팽창되어 밀폐탱크(1)내로 유입되는 유체가 격막(4)을 압축하여 격막(4)에 채워진 유체의 배출이 배출밸브(13)를 통하여 원활히 이루어지면 동작되지 않는 것으로, 상기 배출밸브(13)의 이상이나 유체공급관(P)의 이상이 발생되어 배출밸브(13)가 동작되지 않으면 격막(4)내의 압력은 무한대로 증가되며, 따라서 밀폐배관설비(S)의 압력도 증가되어 설비의 파손을 방지하기 위한 것으로 격막(4)내의 압력이 유체공급관(P)의 압력보다 높은 일정 압력으로 상승되면 유체는 탄성스프링(21)을 밀며 안전밸브(20)를 개방하여 배출구(22)를 통하여 유체가 대기중으로 방출되도록 하므로서 격막(4)내의 이상압력이 해소되도록 하였다.On the other hand, the safety valve 20 is the fluid in the hermetic piping facility (S) is expanded and the fluid flowing into the hermetic tank (1) compresses the diaphragm (4) to discharge the fluid filled in the diaphragm (4) discharge valve (13) If it does not operate smoothly through), if the discharge valve 13 or the abnormality of the fluid supply pipe (P) is generated and the discharge valve 13 is not operated, the pressure in the diaphragm 4 is increased to infinity. Therefore, the pressure of the sealed piping system (S) is also increased to prevent damage to the equipment. When the pressure in the diaphragm (4) is raised to a certain pressure higher than the pressure of the fluid supply pipe (P), the fluid opens the elastic spring (21). By pushing and opening the safety valve 20 so that the fluid is discharged into the atmosphere through the outlet 22, the abnormal pressure in the diaphragm 4 is to be eliminated.
이와 같이 이루어진 본 발명인 보급수를 이용한 압력불변식 밀폐형 팽창탱크는 배관설비의 설계 및 팽창탱크의 용량설계가 용이하며 팽창탱크 설계시 배관설계 내압의 여유를 적게 두어 배관설비에 따른 비용의 절감효과가 있으며, 팽창탱크내에 공기가 봉입되지 않아 압력체크에 따른 유지보수가 필요없으며, 팽창탱크의 설치시 설치위치나 각 배관시스템의 특성에 맞게 조정할 필요가 없어 설치 및 유지관리가 용이하며, 유체의 팽창이 발생시 밀폐배관시스템의 압력의 상승없이 팽창을 흡수할 수 있으며, 팽창탱크의 크기를 종래의 방법에 따른 팽창탱크의 크기보다 20배 이상까지 줄일 수 있어 팽창탱크의 가격, 운반 및 설치가 용이한 이점이 있으며, 밀폐배관내의 유체가 대기중의 산소가 완전 차단되므로 대기의 산소용해로 인한 배관내의 부식을 방지할 수 있어 배관의 수명이 연장되게 되는 이점이 있다.The pressure-invariant hermetic expansion tank using the present inventors made in this way is easy to design the piping equipment and the capacity of the expansion tank, and the cost saving effect according to the piping equipment by reducing the internal pressure of the piping design in the expansion tank design No air is enclosed in the expansion tank, so no maintenance is required according to the pressure check, and installation and maintenance is easy because the expansion tank does not need to be adjusted according to the installation location or characteristics of each piping system.
