본 고안은 가스보일러에 장착되는 플로우 밸브(Flow Valve)에 관한 것으로, 특히 급수관내에 물의 흐름을 감지하는데 적합하도록한 유수감지 플로우 밸브에 관한 것이다.The present invention relates to a flow valve (Flow Valve) is mounted to the gas boiler, and more particularly to a water flow detection flow valve adapted to detect the flow of water in the water supply pipe.

통상의 가스보일러는 제 1 도에 도시한 바와 같이, 버너(1)의 상측에 열교환기(2)가 설치되고, 상기 열교환기(2)에서 가열된 물이 3방향 밸브(3 Way Valve)(3)를 거쳐 응접실, 욕실등의 라지에이터(4)와 방바닥 배관(5)으로 순환되고, 또한 온수열교환기(6)로 공급되게 되어 있으며, 상기 온수열교환기(6)의 급수관(7)에는 플로우 밸브(8)가 연결되어 있다.In the conventional gas boiler, as shown in FIG. 1, a heat exchanger 2 is installed above the burner 1, and the water heated in the heat exchanger 2 is a 3-way valve ( 3) is circulated to the radiator 4 and the bottom pipe 5 of the reception room, bathroom, etc., and is also supplied to the hot water heat exchanger 6, and flows into the water supply pipe 7 of the hot water heat exchanger 6. The valve 8 is connected.

도면에서 9는 인쇄회로기판, 10은 리드선, 11은 펌프, 12는 가스배브, 13은 역풍장치를 위한 드라프트(draft)를 각각 보인 것이며, 화살표 a, b는 각각 난방모드와 온수모드에서 유수방향을 표시한 것이다.In the figure, 9 is a printed circuit board, 10 is a lead wire, 11 is a pump, 12 is a gas barb, 13 is a draft for a backwind device, and arrows a and b are flown in heating mode and hot water mode, respectively. It shows the direction.

상기와 같은 가스보일러에서 플로우 배브(8)는 제 2 도에 도시한 바와 같이, 본체(14)내에 벤츄리튜브(15)가 있으며, 사용자가 온수를 사용하고자 수도꼭지를 틀면, 필터(16)를 통해 물이 유입되어 고압관(17)을 통해 밴츄리튜브(15)에서 물의 유속이 빨라지면서 저압관(18)에 비하여 고압관(17)의 압력이 커지므로 다이어프램(19)이 오른쪽으로 이동되고, 팽창스프링(20)이 압축되면서 슬라이드바(21)가 오른쪽으로 이동되고, 팽창스프링(20)이 압축되면서 슬라이드바(21)가 오른쪽으로 이동하여 접지 플레이트(22)가 마이크로스위치(23)를 접속시키며, 이에 따라 시그널이 인쇄회로기판(9)을 통해 3방향 밸브(3)에 인가되어 난방모드에서 온수모드로 전환되게 한다.In the gas boiler as described above, the flow bar 8 has a venturi tube 15 in the main body 14 as shown in FIG. 2, and when the user turns on the faucet to use hot water, the filter 16 passes through the filter 16. As the water flows in, the flow rate of the water in the banchu tube 15 is increased through the high pressure tube 17, and the pressure of the high pressure tube 17 is increased compared to the low pressure tube 18, so that the diaphragm 19 is moved to the right. As the expansion spring 20 is compressed, the slide bar 21 is moved to the right, and as the expansion spring 20 is compressed, the slide bar 21 is moved to the right, so that the ground plate 22 connects the microswitch 23. Accordingly, a signal is applied to the three-way valve 3 through the printed circuit board 9 to switch from the heating mode to the hot water mode.

그러나, 종래의 플로우 밸브는 구성이 복잡하고 밴츄리튜브(15)가 내장되어있어야 하는 구조이어야 하며, 마이크로스위치(23)가 요구되므로 가격이 증가하는 요인이 되었다.However, the conventional flow valve has a complicated structure and a structure in which the bantu tube 15 is to be built, and the microswitch 23 is required, causing a price increase.

또한, 전체적인 플로우 밸브 싸이즈가 큼으로 해서 보일러내의 배관구조에 연결 조립시 설치공간에 제한을 받게 되며, 계속 반복되는 플로우 밸브의 동작에 의한 다이어프램(19)의 내구성이 필연적으로 보장되어야 하는 등의 여러 문제점이 있었다.In addition, since the overall flow valve size is large, the installation space is limited when the assembly is connected to the piping structure in the boiler, and the durability of the diaphragm 19 due to the continuous operation of the flow valve is inevitably guaranteed. There was a problem.

본 고안이 주 목적은 상기한 바와 같은 문제점을 갖지 않는 가스보일러의 플로우 밸브를 제공함에 있다.The main object of the present invention is to provide a flow valve of a gas boiler that does not have the problems as described above.

본 고안의 다른 목적은 구성을 보다 간소화하면서도 급수관내에 물의 흐름을 정확하게 감지할 수 있도록 한 가스보일러의 플로우 밸브를 제공함에 있다.Another object of the present invention is to provide a flow valve of a gas boiler that can more accurately sense the flow of water in the water supply pipe while simplifying the configuration.

본 고안의 또 다른 목적은 보일러내의 배관구조에 연결 조립시 설치공간에 제한을 받지 않고, 부품의 내구성을 향상시킬 수 있도록 한 가스보일러의 플로우 밸브를 제공함에 있다. 이하, 본 고안에 의한 가스보일러의 플로우 밸브를 첨부 도면에 도시한 실시예에 따라서 설명하면 다음과 같다.Still another object of the present invention is to provide a flow valve of a gas boiler that is capable of improving durability of a component without being limited to an installation space when connecting to a pipe structure in a boiler. Hereinafter, the flow valve of the gas boiler according to the present invention will be described according to the embodiment shown in the accompanying drawings.

제 3 도 내지 제 5 도에 도시한 바와 같이, 통상 가스보일러의 급수관에 연결되는 플로우 밸브에 있어서, 밸브본체(21)내에 유로돌출부(22)를 형성하고, T형 합성수지관(23)을 고정하며, 상기 T형 합성수지관(23)의 수직부에는 합성수지(예를들어 P, E)가 코팅된 황동고리(24)를 승강가능하게 삽입하고, 합성수지관(23)의 하단부에는 고정대(33)를 부착하며, 합성수지관(23)의 수직부 일측에는 스테인레스와이어(25)의 하단부를 고정하여 설치하고, 그 스테인레스와이어(25)의 상단부와 합성수지관(23) 사이에는 스테인레스와이어(25)를 외향으로 탄력지지하는 팽창스프링(26)을 설치하며, 밸브본체(21)에 고정한 가이드(27)에는 이동봉(28)을 좌우로 이동 가능하게 설치하여, 상기 스테인레스와이어(25)와 연결핀(29)으로 유동가능하게 연결하고, 상기 이동봉(28)의 외측단부에는 마이크로스위치(30)를 접속시키는 접지플레이트(31)를 고정하며, 이동봉(28)의 주위에 고무벨로우즈(32)를 삽입하여서 된 것이다.3 to 5, in the flow valve normally connected to the water supply pipe of the gas boiler, the flow path protrusion part 22 is formed in the valve body 21, and the T-type synthetic resin pipe 23 is fixed. And, the vertical portion of the T-type synthetic resin tube 23 is inserted into the brass ring 24 coated with synthetic resin (for example, P, E) to be lifted, and the fixing table (33) at the lower end of the synthetic resin tube (23) And a lower end of the stainless wire 25 is installed on one side of the vertical part of the synthetic resin pipe 23, and the stainless wire 25 is outwardly connected between the upper end of the stainless wire 25 and the synthetic resin pipe 23. The expansion spring 26 to support the elasticity is installed, the guide 27 fixed to the valve body 21 is installed to move the movable rod 28 to the left and right, the stainless wire 25 and the connecting pin 29 Fluidly connected to the outer end of the movable rod 28 It is fixed, and the ground plate 31 for connecting the microswitch 30, hayeoseo inserting the rubber bellows (32) around the yidongbong 28.

이와같이된 본 고안의 플로우 밸브는 제 1 도와 같은 가스보일러의 플로우 밸브(8)위에 사용된다.The flow valve of the present invention thus used is used on the flow valve 8 of the gas boiler as the first degree.

이하, 제 1 도를 참조하여 본 고안에 의한 플로우 밸브의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the flow valve according to the present invention with reference to Figure 1 as follows.

제 3 도는 난방모드시의 상태를 보인 것으로, 이러한 난방모드에서는 밸브본체(21)에 물이 정체되었다가 제 4 도와 같이 밸브본체(21)내로 급수가 유입되면, 유로돌출부(22) 입구에서 급수의 유속이 상승되어 합성수지로 코딩된 황동고리(24)가 위로 올라가면서 합성수지관(23)에 연결된 스테인레스와이어(25)가 오므라지고, 이에 따라 이동봉(28)이 이동하여 고무벨로우즈(32)가 수축되면서 접지 플레이트(31)가 마이크로스위치(30)를 접속시켜주어 신호가 인쇄회로기판(9)을 통해 3방향 밸브(3)를 난방모드에서 온수모드로 전환시켜주어 열교환기(2)로부터 나온 고온의 난방수가 온수열교환기(6)로 유입되어 온수를 사용할 수 있다.3 shows the state in the heating mode. In this heating mode, when water is stagnated in the valve body 21 and water is introduced into the valve body 21 as shown in FIG. 4, water is supplied from the inlet of the flow path protrusion 22. As the flow rate of the copper ring 24, which is coded with synthetic resin, is raised, the stainless wire 25 connected to the synthetic resin pipe 23 is lifted, and the movable rod 28 is moved to shrink the rubber bellows 32. The ground plate 31 connects the micro switch 30 so that a signal is transferred from the heating mode to the hot water mode through the printed circuit board 9 so that the high temperature from the heat exchanger 2 can be reached. Heating water is introduced into the hot water heat exchanger (6) can use hot water.

이와같은 제 4 도의 상태에서 온수사용을 중지하면, 황동고리(24)가 유로돌출부(22)내에 급수의 유속이 없어지므로 제 3 도와 같이 고정대(33)까지 가라앉게 되며, 스테인레스와이어(25)는 팽창스프링(26)의 팽창력에 의해 외측으로 버어지고 이동봉(28)이 외측으로 이동하여 접지플레이트(31)가 마이크로스위치(30)에서 난방모드로 전환되어 난방 부하를 주게 된다.When the use of hot water is stopped in the state of FIG. 4, since the flow rate of the water supply in the flow passage part 22 is lost, the brass ring 24 sinks to the fixing table 33 as shown in FIG. 3, and the stainless wire 25 is It is discarded outward by the expansion force of the expansion spring 26 and the movable rod 28 is moved outward so that the ground plate 31 is switched to the heating mode in the micro switch 30 to give a heating load.

이상에서 설명한 바와 같이 본 고안의 스테인레스와이어, 황동고리, 합성수지관, 고무벨로우즈 등의 적은 부품에 의하여 간다한 구성으로 되어 있고, 제작이 간편할 뿐아니라 콤팩트한 제작이 가능하며, 보일러내에 장착하는데 배관구조상 간단하여 연결조립이 가능하게 되는 등의 효과가 있다.As described above, the stainless steel wire, brass ring, synthetic resin pipe, rubber bellows, etc. of the present invention have a simple configuration, and are easy to manufacture and compact, and can be installed in a boiler. It is simple in structure, so that connection assembly can be performed.
