본 고안은 가스보일러에 있어 난방수를 가열시킴에 따라 발생되는 수증기나 기포 제거 및 저수위를 감지할 수 있도록 한 가스보일러용 저수위 자동 에어변에 관한 것이다.The present invention relates to a low-level automatic air valve for a gas boiler that can detect the water vapor or bubbles generated and low water level generated by heating the heating water in the gas boiler.

일반적으로 가스보일러는 가스연료를 이용하여 연소시킨 연소열로서 난방수가 충만된 열교환기를 가열하고, 열교환기내에서 가열된 난방수를 온수 배관파이프를 따라 강제 순환시킴으로서 실내온도를 난방하도록 하였던 것으로 열교환기를 가열시킴에 따라서 가열된 난방수에서 발생하는 수증기나 기포등은 난방수의 순환과 더불어 난방효과를 저해하는 요인이 되었던 것이다.In general, a gas boiler heats a heat exchanger filled with heating water as combustion heat combusted using gaseous fuel, and heats the heat exchanger by forcibly circulating the heated water in the heat exchanger along the hot water pipe pipe to heat the room temperature. Accordingly, steam or bubbles generated from heated heating water may be a factor that inhibits the heating effect along with circulation of the heating water.

따라서 종래에는 난방수에는 발생하는 수증기나 기포등을 제거하기 위해 열교환기와 온수배관파이프 사이에 공기배관이나 에어밸브를 설치하여 기포등을 제거하도록 하였으나 이는 열교환기내에서 집단으로 발생하는 기포가 외부로 배출되면서 기포와 함께 난방수가 역류하거나 심한 소음을 동반하게 되는 문제점이 있었으며 공기배관은 항상 급수탱크보다 높게 설치하여야만 하는 불합리한 점이 있었다.Therefore, conventionally, air pipes or air valves are installed between the heat exchanger and the hot water pipe in order to remove water vapor or bubbles generated in the heating water, so that bubbles are removed from the heat exchanger. As a result, there was a problem that the heating water flowed back with bubbles or accompanied by severe noise, and the air piping was always unreasonable to be installed higher than the water supply tank.

본원 고안은 이와 같은 문제점을 감안 해결하기 위한 것으로 이를 첨부된 도면에 따라서 그 구성과 작용효과를 상세히 설명하면 다음과 같다.The present invention is to solve the above problems in consideration of the configuration and effect according to the accompanying drawings in detail as follows.

본원 고안의 저수위 자동 에어변은 원통체로 된 몸체(1)내부에 부구체(2)를 수용시킨 다음 뚜껑체(3)와 함께 캡(4)을 조립하여 에어변을 형성하여 난방수를 가열시킴을 따라 발생되는 기포나 수증기를 자동배출하도록 하고 또한, 보일러의 저수위를 감지하도록 한 것으로 제1도 내지 제3도에 도시한바와 같이 저수위 자동 에어변은 에어변 몸체(1)를 원통체로 형성하여 몸체(1)내에 부구체(2)를 충분히 수용할 수 있는 크기로 만들어지고 있으며, 몸체(1)의 하부에는 물과 함께 기포등이 몸체내에 유입될 수 있도록 구멍(12)을 뚫고 있는 접속구(11)를 몸체(1)와 일체로 형성하며, 접속구(11)의 외원주에는 나사부(13)를 가공하여 도시하지 않은 열교환기와 온수배관 파이프 사이에 접속되는 접속관과 나사 결합하도록 하고 있는 것이다.The low water level automatic air valve of the present invention accommodates the subsidiary body 2 inside the cylindrical body 1 and then assembles the cap 4 together with the lid 3 to form an air valve to heat the heating water. It is to automatically discharge the bubbles or water vapor generated along the, and to detect the low water level of the boiler, as shown in Figures 1 to 3 low-level automatic air valve is to form the air valve body (1) as a cylindrical body The body 1 is made to have a size enough to accommodate the subsidiary body 2, the lower portion of the body 1, the connection hole for drilling holes 12 so that bubbles and the like can be introduced into the body with water ( 11) is formed integrally with the body (1), the outer circumference of the connector 11 is to be screwed with the connecting tube connected between the heat exchanger and the hot water pipe (not shown) by processing the screw portion (13).

몸체(1)의 상단부에는 수나사부(14)를 형성하여 캡(4)과 나사 결합하도록 하고 있다.A male screw portion 14 is formed at the upper end of the body 1 so as to be screwed with the cap 4.

부구체(2)는 몸체(1)내에 수용되어 몸체(1)내로 유입되는 물과 기포에 의한 상, 하 운동으로 밸브(5)를 구동하도록 하고 있는 것이다.The substructure 2 is accommodated in the body 1 so as to drive the valve 5 in the up and down motion by water and bubbles flowing into the body 1.

부구체(2)는 물에 뜰수 있는 재질로 되고, 부구체(2)의 외원주에는 길이 방향으로 가이드홈(21)을 다수개 형성하여 접속구(11)를 통해 유입된 기포가 가이드홈(21)을 따라 에어변 상측으로 쉽게 유입되도록 하고 있다.The subsidiary body 2 is made of a material that can float on water, and a plurality of guide grooves 21 are formed on the outer circumference of the subsidiary body 2 in the longitudinal direction so that bubbles introduced through the connector 11 are guide grooves 21. ) So that it is easy to flow into the upper side of the air valve.

뚜껑체(3)는 캡(4)과 함께 에어변몸체(1)상부에 조립되어 에어변 몸체(1)내를 밀페시키도록 하고 있는 것이다.The lid 3 is assembled to the upper side of the air side body 1 together with the cap 4 so as to seal the inside of the air side body 1.

뚜껑체(3)의 저면(3a) 즉, 몸체(1)내에 수용되는 면에는 공기배출공(32)을 뚫고있는 밸브시트부(31)와 밸브고정부(33)를 형성하며, 뚜껑체 상단면(3b)에는 공기배출공(32)과 연통하는 공기배출구(34)와 리드스위치(S)를 설치하고 있다.On the bottom surface 3a of the lid 3, that is, the surface accommodated in the body 1, a valve seat 31 and a valve fixing part 33 that penetrate the air discharge hole 32 are formed. The air discharge port 34 and the reed switch S which communicate with the air discharge hole 32 are provided in the surface 3b.

뚜껑체(3)의 밸브고정부(33)에 고정되는 밸브(5)는 밸브시트부(31)의 공기배출공(32)을 개폐하는 기능과 더불어 밸브(5)의 한끝단에 고정하고 있는 영구자석(6)의 자계에 의해 리드스위치(S)와 접점을 이루어 에어변의 수위를 검출하도록 하고 있는 것이다.The valve 5 fixed to the valve fixing part 33 of the lid 3 has a function of opening and closing the air discharge hole 32 of the valve seat 31 and fixed to one end of the valve 5. The magnetic field of the permanent magnet 6 makes contact with the reed switch S to detect the level of the air valve.

밸브(5)의 몸체(51)에는 패킹끼움부(52)를 형성하여 패킹끼움부(52)에 고무와 같은 패킹(33)을 끼워 밸브시트부(31)의 공기배출공(32)을 개폐하도록 하며, 몸체(51)의 한끝에는 영구자석(6)을 감착 고정하고 있다.The body 51 of the valve 5 forms a packing fitting portion 52 to insert a packing 33 such as rubber into the packing fitting portion 52 to open and close the air discharge hole 32 of the valve seat portion 31. One end of the body 51 is fixed to the permanent magnet (6).

이와 같이 구성하고 있는 밸브(5)는 한쪽 끝단이 상, 하로 회동되게 뚜껑체(3)의 밸브고정부(33)에 고정하고 있다.The valve 5 configured in this manner is fixed to the valve fixing portion 33 of the lid 3 so that one end thereof rotates up and down.

밸브(5)를 밸브고정부(33)에 고정시킬때에 가는 강선(54)으로 밸브(5)와 밸브고정부(33)를 연결하여 밸브몸체(51)에 고정된 영구자석(6)의 자중에 의해 영구자석(6)이 고정된 밸브(5)의 한쪽단이 항상 처져있는 상태를 유지하도록 조립하고 있는 것으로 이는 수위에 따라 상승되는 부구체(2)에 의해 밸브(5)를 상승시켜 공기배출공(32)을 막게됨과 동시에 영구자석(6)이 리드스위치(S)와 접점을 이루도록 하여 에어변의 만수위 상태를 감지토록 하고 있는 것이다.When the valve 5 is fixed to the valve fixing part 33, the steel wire 54 connects the valve 5 and the valve fixing part 33 to the permanent magnet 6 fixed to the valve body 51. It is assembled so that one end of the valve 5 to which the permanent magnet 6 is fixed by self-weight is always drooping. This is caused by raising the valve 5 by the subsidiary body 2 which rises with the water level. The air discharge hole 32 is blocked and at the same time the permanent magnet 6 makes contact with the reed switch S to detect the full water level of the air valve.

미설명 부호 41은 공기배출구와 리드스위치를 인출하는 홀이며, 0는 0-링이다.Reference numeral 41 is a hole for drawing the air outlet port and the reed switch, and 0 is a 0-ring.

이와 같이 조립, 구성하고 있는 본 고안의 저수위 자동 에어변의 사용상태와 작용효과를 설명하면 다음과 같다.Referring to the state of use and operation of the low-level automatic air valve of the present invention that is assembled and configured as described above are as follows.

제4도와 같이 접속관(H)에 연결하고 있는 접속구(11) 통해 몸체(1)의 하부로 유입된 물은 몸체(1)의 하부로부터 차오르면서 부구체(2)를 상승시키게 되고 물에의해 상승되는 부구체(2)는 영구자석(6)의 자중에 의해 처져있던 밸브(5)의 한끝단을 밀어올리게 된다. 이때 에어변몸체(1)내의 공기는 물의 수위가 높아짐에 따라공기 배출공(32)을 통해 배출되는 상태이다.As shown in FIG. 4, the water flowing into the lower part of the body 1 through the connection port 11 connected to the connecting pipe H is lifted from the lower part of the body 1, thereby raising the substructure 2. The subsidiary body 2 which is lifted up pushes up one end of the valve 5 which has been sag by the weight of the permanent magnet 6. At this time, the air in the air valve body (1) is discharged through the air discharge hole 32 as the water level is increased.

따라서 몸체내로 유입된 물에 의해 최고점까지 상승된 부구체(2)가 회동시킨 밸브(5)는 뚜껑체(3)에 형성하고 있는 밸브시트부(31)의 공기배출공(32)을 패킹(53)이 막게 되는 것이다.Therefore, the valve 5 rotated by the subsidiary body 2 raised to the highest point by the water flowing into the body packs the air discharge hole 32 of the valve seat 31 formed in the lid 3. 53) will be blocked.

이와 같이 공기를 모두 배출시킨 다음에 공기배출공(32)을 막게 되어 공기배출공(32)을 통해 물이 역류되는 일은 없게 된다. 또한, 영구자석(6)이 회동되어 리드스위치(S)를 구동할 수 있는 자계범위내에 들게되면 리드스위치(S)는 "ON"되고 리드스위치(S)의 ON상태를 콘트롤러에 송출하여 에어변내의 수위가 만수 상태임을 표시하게 되는 것이다. (제4a도)As such, after the air is discharged, the air discharge hole 32 is blocked, so that water does not flow back through the air discharge hole 32. In addition, when the permanent magnet 6 is rotated to fall within the magnetic range capable of driving the reed switch S, the reed switch S is "ON", and the ON state of the reed switch S is sent to the controller, thereby providing air flow. It is to indicate that the water level in the state is full. (Figure 4a)

제4a도와 같이 난방수를 가열시킴에 따라 발생되는 기포는 접속구(11)를 통해 몸체(1)내로 유입되고, 몸체(1)내로 유입된 공기는 부구체(2)의 가이드홈(21)을 따라 상승되어 몸체(1)의 상단부에 모이게된다.Bubbles generated by heating the heating water as shown in Figure 4a is introduced into the body (1) through the connection port 11, the air introduced into the body (1) guides the guide groove 21 of the substructure (2) It rises along and gathers at the upper end of the body 1.

이때 몸체(1)의 상단부로 유입된 공기의 부피만큼 에어변내의 물의 수위는 떨어지게 되고, 수위가 떨어지게 됨에 따라서 부구체(2) 또한 동일하게 하강하게 된다. 그래서 밸브(5)를 상승시키고 있던 부구체(2)가 하강함에 따라 밸브(5)는 영구자석(6)의 자중에 의해 밸브(5)의 한끝단을 처지게 되고 밸브(5)의 한끝단이 처짐에 따라 영구자석(6)의 자계범위내에 있던 리드스위치(S)의 접점이 떨어지게 되어 리드스위치(S)는 OFF되는 것이다.At this time, the water level of the water in the air valve is dropped by the volume of air introduced into the upper end of the body (1), and as the water level drops, the spherical body (2) is also lowered in the same way. Thus, as the subsidiary body 2, which is raising the valve 5, descends, the valve 5 sags one end of the valve 5 by the weight of the permanent magnet 6, and one end of the valve 5 This deflection causes the contact of the reed switch S in the magnetic field of the permanent magnet 6 to fall, and the reed switch S is turned off.

이와 동시에 밸브시트부(31)의 공기배출공(32)을 막고있던 밸브(5)의 하강으로 패킹(53)이 떨어져 공기배출공(32)을 개방시키게 되면, 몸체(1)의 상단부에 모여 있던 공기는 공기배출공(32)을 따라서 외부로 배출시키게 되는 것이다.At the same time, when the packing 53 is dropped and the air discharge hole 32 is opened due to the lowering of the valve 5 which is blocking the air discharge hole 32 of the valve seat 31, the upper portion of the body 1 gathers. The air was discharged to the outside along the air discharge hole (32).

따라서 몸체(1)내에서 배출되는 공기의 부피만큼 몸체(1)내로 물이 차오르게 되어 또 다시 부구체(2)를 상승시키게 되는 것이다.Therefore, the water is filled into the body 1 by the volume of air discharged from the body 1, and the float 2 is raised again.

부구체(2)의 상승에 따라 밸브(5)를 상승시켜 또다시 공기배출공(32)을 막게될 때 영구자석(6)은 리드스위치(S)를 ON시키게 되는 일련의 순환과정을 반복하므로서 난방수에서 발생된 기포를 제거하게 되는 것이다.When the valve 5 is raised as the subsidiary body 2 rises, and the air discharge hole 32 is blocked again, the permanent magnet 6 repeats a series of cycles in which the reed switch S is turned on. Bubbles generated in the heating water are removed.

이와같이 본원 고안의 저수위 자동에어변은 에어변내에 유입되는 물과 공기에 의해서 상, 하로 운동하는 부구체(2)가 밸브(5)를 구동시켜 공기배츨공(32)을 자동으로 개, 폐하여 공기를 배출시키고 또한 부구체에 의해 개, 폐되는 밸브의 상태를 리드스위치(S)가 감지하여 에어변내의 수위를 감지하게 되는 것이다.As described above, the low water level automatic air valve of the present invention has a sub-sphere 2 moving up and down by water and air flowing into the air valve to drive the valve 5 to automatically open and close the air discharge hole 32. The reed switch (S) detects the state of the valve to discharge the air and is opened and closed by the spherical body to detect the water level in the air valve.
