Description

격막튜브 파손감지수단을 구비한 밀폐식 팽창탱크{Closed type expansion tank with breakage detection means of bladder}[0001] The present invention relates to a closed type expansion tank with breakage detection means of bladder,

본 발명은 밀폐식 팽창탱크에 관한 것으로서, 특히 격막튜브의 손상이나 파손 등에 의해 누수가 발생하는 경우 이를 신속하게 감지할 수 있는 격막튜브 파손감지수단을 구비한 밀폐식 팽창탱크에 관한 것이다.The present invention relates to an enclosed expansion tank, and more particularly, to an enclosed expansion tank having a diaphragm tube breakage detecting means capable of quickly detecting leakage of water due to damage or breakage of a diaphragm tube.

일반적으로 주택이나 공장 및 대형 건물의 실내 온도는 냉난방 시스템의 배관계통을 따라 유동하는 물과 같은 유체(냉난방수)를 가열 또는 냉각시킨 후 이를 순환 펌프를 이용하여 강제 순환시킴으로써 열이나 냉기를 이용하여 실내 온도를 조절하며, 이러한 냉난방 시스템은 냉난방 배관을 따라 흐르는 냉온수, 즉 배관수의 순환이 지속적으로 이루어질 때 비로소 요구하는 냉난방 효과를 꾀할 수 있도록 되어 있다.Generally, the room temperature of houses, factories, and large buildings is measured by heating or cooling a fluid (such as water) flowing along the piping system of the heating / cooling system, forcing it to circulate using a circulation pump, So that the cooling and heating system can provide the cooling and heating effect required when the circulation of the cold and hot water flowing along the cooling and heating pipe, that is, the circulation of the pipe water, is continuously performed.

이와 같은 냉난방 시스템에 있어 냉난방 배관을 따라 유동하는 배관수의 압력을 일정 수준으로 유지시켜 배관의 연결 부위를 통한 누수와 배관의 파손을 방지할 필요가 있다.In such an air-conditioning system, it is necessary to maintain the pressure of the water flowing along the cooling / heating pipe at a certain level to prevent leakage of water through the connection portion of the pipe and damage to the pipe.

이를 위해, 냉난방 배관을 따라 유동하는 배관수의 온도가 상승하여 배관수가 팽창하게 될 경우에는 냉난방 배관과 연결되어 배관수를 팽창탱크로 보내고, 반대로 팽창수의 온도가 내려감에 따라 배관수가 수축을 하게 될 경우에는 팽창탱크에 저장된 보충수를 다시 냉난방 배관 측으로 공급하여 배관수의 압력을 일정 수준으로 유지해주고 있다.To this end, when the temperature of the pipe flowing along the cooling / heating pipe rises and the pipe water expands, it is connected to the cooling / heating pipe to send the pipe water to the expansion tank. Conversely, as the temperature of the expansion water decreases, The supplementary water stored in the expansion tank is supplied to the cooling / heating piping side to maintain the pressure of the piping water at a certain level.

이와 같이, 냉난방 시스템에서 냉난방 배관의 압력 상승을 흡수하여 냉난방 시스템이 일정 압력 이상으로 올라가지 않도록 하는 것이 팽창탱크이며, 이러한 팽창탱크는 개방형과 밀폐형으로 구분된다.As described above, it is an expansion tank that absorbs a pressure rise of the cooling / heating pipe in the cooling / heating system so that the cooling / heating system does not rise above a certain pressure. Such an expansion tank is divided into an open type and a closed type.

개방형 팽창탱크의 경우 외부의 공기와 배관수가 직접 접촉하기 때문에 배관 부식, 이물질의 유입, 오염 등이 생길 수 있다. 이러한 문제를 해결하기 위하여 밀폐형 팽창탱크가 일반적으로 사용된다.In the case of an open expansion tank, piping corrosion, foreign matter inflow, contamination, etc. may occur due to direct contact between the outside air and the piping number. In order to solve such a problem, a closed expansion tank is generally used.

특히 밀폐형 팽창탱크는 탱크본체 내부에 물과 공기가 접촉하지 않도록 내측에 Butyl Rubber, EPDM 등의 고무재질로 이루어진 격막튜브(Bladder, Diaphragm)가 구비되어 있다.Particularly, the sealed expansion tank is provided with a diaphragm tube made of a rubber material such as butyl rubber or EPDM on the inner side so that water and air do not come into contact with the inside of the tank body.

그러나 격막튜브는 고무재질로 이루어져 강도가 약하기 때문에 장시간 사용하거나 내부에 이물질이 유입되면 파손될 우려가 있다. 이러한 경우 온도 변화에 따른 냉난방 배관 및 팽창탱크 내의 배관수가 팽창하게 되고, 팽창된 배관수는 결국 냉난방 배관의 압력을 급격히 상승시키게 되어 냉난방 배관의 파손과 기기의 고장 원인이 되는 문제점이 있다.However, since the diaphragm tube is made of a rubber material and has a weak strength, it may be used for a long time or may be damaged if foreign substances are introduced into the diaphragm tube. In this case, the number of pipes in the cooling / heating piping and the expansion tank due to the temperature change expands, and the number of the expanded piping rapidly increases the pressure of the cooling / heating piping, thereby causing breakage of the cooling / heating piping and failure of the equipment.

또한, 탱크본체는 일정한 강도를 가지는 철강재나 복합소재의 압력 용기로 제작되므로 내부의 격막튜브 상태를 파악하기 어려워, 격막튜브의 파손이나 설치의 잘못을 감시할 수 없는 문제가 있다.In addition, since the tank body is made of a steel or composite material pressure vessel having a certain strength, it is difficult to grasp the state of the diaphragm tube therein, and there is a problem that the diaphragm tube can not be inspected for damage or erroneous installation.

FIG.

본 발명에 의한 격막튜브 파손감지수단을 구비한 밀폐식 팽창탱크는 냉난방 시스템에서 배관(P)의 압력을 조절하기 위하여 사용하는 밀폐식 팽창탱크로서, 탱크본체(10)와, 상기 탱크본체(10) 내부에 설치되는 격막튜브(20)와, 상기 탱크본체(10)에 설치되는 격막튜브 파손감지수단(30)과, 상기 격막튜브 파손감지수단(30)으로부터 신호를 받는 신호수신부(40)를 포함하여 구성된다.The closed expansion tank having the diaphragm tube breakage detecting means according to the present invention is an enclosed expansion tank used for controlling the pressure of the pipe P in the cooling and heating system. The closed expansion tank includes a tank body 10, A diaphragm tube breakage detecting means 30 installed in the tank main body 10 and a signal receiving unit 40 receiving a signal from the diaphragm tube breakage detecting means 30, .

상기 탱크본체(10)는 밀폐식 팽창탱크의 전체 외관을 형성하는 것으로서, 상단에 배관(P)이 연결되고, 내부에 빈 공간 즉 공기가 채워지는 공기실(10a)이 형성된다. 이러한 탱크본체(10)는 측면에 배출구(11)가 돌출 형성되고, 보호패널(12)이 설치된다.The tank main body 10 forms the entire outer surface of the closed expansion tank, and a pipe P is connected to the upper end thereof, and an air chamber 10a filled with an empty space, that is, air, is formed therein. In this tank body 10, a discharge port 11 is formed to protrude from the side surface and a protection panel 12 is installed.

상기 배출구(11)는 탱크본체(10)의 측면 하단부분에 설치되는 것으로서, 길이가 짧은 일직선 파이프와 같은 형태를 갖고, 탱크본체(10) 내부의 공기실(10a)과 연통된다.The discharge port 11 is installed at the lower side of the tank body 10 and has the same shape as a short straight pipe and communicates with the air chamber 10a inside the tank body 10. [

상기 보호패널(12)은 격막튜브 파손감지수단(30)을 보호하기 위한 것으로서, 배출구(11)와 격막튜브 파손감지수단(30)을 둘러싼다.The protection panel 12 is for protecting the diaphragm tube breakage detecting means 30 and encloses the outlet 11 and the diaphragm tube breakage detecting means 30. [

상기 격막튜브(20)는 탱크본체(10) 내부에 상하로 길게 배치되는 형태로 고정되며, 고무와 같은 신축성 재질로 이루어져 팽창 및 수축이 가능하다. 그리고, 격막튜브(20)는 상측 부분이 배관(P)과 연결되어 배관(P) 내부에 흐르는 배관수의 압력에 따라 배관수가 유입 또는 유출된다.The diaphragm tube 20 is fixed to the tank body 10 in a vertically long manner and is made of a stretchable material such as rubber and is capable of expanding and contracting. The upper portion of the diaphragm tube 20 is connected to the piping P so that the piping water flows in or out according to the pressure of the piping water flowing in the piping P.

이렇게 격막튜브(20) 내부에 배관수가 유입됨으로써 격막튜브(20)를 기준으로 격막튜브(20) 내부에 수실(水室,20a)이 형성되고 격막튜브(20) 밖으로 공기실(10a)이 형성된다. As a result, the water chamber 20a is formed in the diaphragm tube 20 with respect to the diaphragm tube 20 and the air chamber 10a is formed outside the diaphragm tube 20 do.

좀 더 부연하면, 배관수의 온도 상승에 의해 배관수가 팽창하게 되면 팽창된 배관수가 상대적으로 낮은 압력인 팽창탱크의 격막튜브(20) 내부 공간인 수실(20a)로 유입되면서 배관(P)의 압력 상승이 방지된다. 그리고, 배관(P) 내의 배관수의 온도가 낮아져 배관(P)의 압력이 낮아지면 상대적으로 높은 압력인 팽창탱크의 격막튜브(20) 내부에 저장된 배관수가 다시 배관(P)으로 환원됨으로써 배관(P)의 압력 감소가 방지된다.More specifically, when the pipe water expands due to the temperature rise of the pipe water, the expanded pipe flows into the water chamber 20a, which is an internal space of the diaphragm tube 20 of the expansion tank having a relatively low pressure, The rise is prevented. When the temperature of the pipe in the pipe P is lowered and the pressure of the pipe P is lowered, the number of pipes stored in the diaphragm tube 20 of the expansion tank, which is a relatively higher pressure, is reduced back to the pipe P, P is prevented.

상기 격막튜브 파손감지수단(30)은 탱크본체(10)의 배출구(11)에 수평이 되게 삽입되고, 격막튜브(20)의 파손에 의해 탱크본체(10) 내부로 누출된 배관수가 배출구(11)를 통해 외부로 유출될 때 배관수에 의한 부력으로 경사지게 기울어짐으로써 배관수가 유출됨을 감지한다.The diaphragm tube breakage detecting means 30 is horizontally inserted into the discharge port 11 of the tank main body 10 and the number of pipes leaked into the tank main body 10 due to breakage of the diaphragm tube 20 ), It is inclined by the buoyancy caused by the number of piping, thereby detecting that the piping water flows out.

좀 더 자세히 설명하면, 본 발명에서 사용되는 격막튜브 파손감지수단(30)은 탱크본체(10)의 배출구(11) 내부에서 유동하는 배관수를 감지하는 플로팅타입 유체감지 스위치이다.More specifically, the diaphragm tube breakage detecting means 30 used in the present invention is a floating type fluid sensing switch for sensing the number of pipes flowing inside the discharge port 11 of the tank body 10.

이러한 플로팅타입 유체감지 스위치는 부싱(31)과, 상기 부싱(31)에 체결되는 유니온 너트(32)와, 상기 유니온 너트(32)에 연결되는 플로트(33)와, 상기 플로트(33)의 움직임을 감지하는 센싱부(34)를 포함하여 구성된다.The floating type fluid sensing switch includes a bushing 31, a union nut 32 fastened to the bushing 31, a float 33 connected to the union nut 32, And a sensing unit 34 for sensing a sensing signal.

상기 부싱(31)은 탱크본체(10)의 배출구(11)와 유니온 너트(32) 사이에 선택적으로 설치된다. 즉 부싱(31)은 배출구(11)에 나선체결 방식으로 삽입되어 결합된다.The bushing 31 is selectively installed between the discharge port 11 of the tank body 10 and the union nut 32. That is, the bushing 31 is inserted and coupled to the discharge port 11 in a spiral fastening manner.

상기 유니온 너트(32)는 부싱(31)이 설치되지 않을 경우에는 탱크본체(10)의 배출구(11)에 직접 나선체결 방식으로 삽입되어 연결되고, 부싱(31)이 설치될 경우에는 부싱(31)에 나선체결 방식으로 삽입되어 연결된다.When the bushing 31 is not installed, the union nut 32 is directly inserted into and connected to the discharge port 11 of the tank body 10 in a spiral fastening manner. When the bushing 31 is installed, the bushing 31 ), And are inserted and connected.

상기 플로트(33)는 배출구(11) 안쪽에 수평방향으로 삽입되어 배출구(11)를 통해 외부로 유출되는 배관수에 의해 위쪽으로 들어 올려져 기울어진다. 부연설명을 하면, 격막튜브(20)가 파손되어 격막튜브(20) 내부의 배관수가 탱크본체(10)의 공기실(10a)로 누설되면, 이 배관수는 배출구(11)를 통해 탱크본체(10) 외부로 배출되는데, 이때 배출구(11)를 유동하는 배관수에 의해 플로트(33)의 일측 끝부분이 부력에 의해 위쪽으로 들림으로써 수평상태를 유지하던 플로트(33)가 한쪽으로 기울어진 경사진 상태를 취하게 된다.The float 33 is horizontally inserted into the discharge port 11 and is lifted upward by the number of pipes flowing out to the outside through the discharge port 11 and is inclined.
