On the other hand, in the case of a hot water heating boiler as shown in Figure 1, the hot water coil (not shown) is built in the heat exchanger (1), the water supply line (D) and the hot water discharge line (E) both sides of the hot water coil It forms a structure that is in communication with each tip.
상기 압력조절밸브(40)는 도 2에 도시된 바와 같이, 밸브안착부(41c)와, 팽창라인(C)에 직렬로 연통되는 제1·2연결부(41a,41b)가 형성되어진 하우징(41)과 ; 하우징(41)의 밸브안착부(41c)를 밀폐시키는 캡(42) ; 하우징(41)의 밸브안착부(41c)에 내장되어 팽창라인(C)으로의 유동체의 흐름을 선택적으로 개폐시키는 양방향 체크밸브(43)로 구성되어진 구조를 이룬다. 여기서, 상기 양방향 체크밸브(43)는, 스프링(43c)을 매개로 캡(42)에 탄발적으로 지지되는 제1체크밸브(43a)와, 스프링(43d)을 매개로 제1체크밸브(43a)에 탄발적으로 지지되는 제2체크밸브(43b)로 이루어진다.As shown in FIG. 2, the pressure regulating valve 40 includes a valve seat 41c and a housing 41 in which first and second connecting portions 41a and 41b communicate in series with the expansion line C. ) And; A cap 42 for sealing the valve seat 41c of the housing 41; It is built in the valve seat 41c of the housing 41 to form a structure consisting of a two-way check valve 43 for selectively opening and closing the flow of the fluid to the expansion line (C). Here, the bidirectional check valve 43, the first check valve 43a which is elastically supported by the cap 42 via the spring 43c, and the first check valve 43a via the spring 43d. ) And a second check valve 43b that is supported elastically.
이러한 종래 보일러의 설치작업을 개략적으로 설명해 보면, 우선 건축물 시공시 난방수 보충라인(A)과, 난방라인(B), 급수라인(D) 및 온수배출라인(E)을 형성하면서, 이들에 구비되는 각 구성요소들(10,20,30)을 설치하는 한편, 압력조절밸브(40)를 갖춘 팽창라인(C)을 매개로 보일러의 열교환기(1)에 팽창탱크(2)를 연통시킨다. 이후, 난방라인(B)의 난방출수부(B1)와 난방입수부(B2)를 보일러의 열교환기(1)에 연통시키고, 열교환기(1)에 급수라인(D)과 온수배출라인(E)을 연통시켜서 보일러 설치작업을 완료한다.When the installation work of the conventional boiler is described schematically, the heating water replenishment line (A), the heating line (B), the water supply line (D) and the hot water discharge line (E) are first provided in the building construction. While installing the respective components (10, 20, 30), the expansion tank (2) is in communication with the heat exchanger (1) of the boiler via an expansion line (C) having a pressure control valve (40). Thereafter, the heating outlet part B1 and the heating inlet part B2 of the heating line B are connected to the heat exchanger 1 of the boiler, and the water supply line D and the hot water discharge line E are connected to the heat exchanger 1. ) To complete the boiler installation work.
이와 같이 설치된 보일러를 정상적으로 가동시키기 위해서는, 보일러를 시동운전하여 난방라인(B)과 열교환기(1)에 잔류된 공기를 외부로 배출시켜서 이들 난방라인(B)과 열교환기(1)에 난방수가 충진하여 되도록 해야한다.In order to operate the boiler normally installed in this way, the boiler is started and operated to discharge the air remaining in the heating line B and the heat exchanger 1 to the outside, and the heating water is heated in these heating lines B and the heat exchanger 1. To be filled.
보일러의 시동운전을 보다 상세히 설명해 보면, 난방라인(B)의 에어배출용 수동밸브(30)를 오픈시킨 상태에서 보일러를 가동시키면, 저수위센서(50)로부터 저수위가 감지되므로{초기 시동운전시에는 난방라인(B)과 열교환기(1)에 난방수가 충진되지 않은 상태이므로}, 보일러가 점화되지 않은 상태를 유지하면서 솔레노이드밸브(10)가 오픈되어, 난방수 보충라인(A)으로부터의 냉수가 열교환기(1)와 이에 연통된 난방라인(B)으로 공급되면서, 잔류된 공기의 대부분은 에어배출용 수동밸브(30)를 통해서 배출된다. 한편, 열교환기(1)의 난방출수부(B1)까지 난방수가 보충되면, 열교환기(1)의 난방출수부(B1)로부터 팽창라인 연결부까지의 공기는 열교환기(1)의 상부에 격리되어 난방라인(B)의 에어배출용 수동밸브(30)로 배출되지 못하지만, 난방수 보충라인(A)으로부터의 급수압력에 의해서 압력조절밸브(40)의 제1체크밸브(43a)가 오픈되므로, 열교환기(1)의 상부에 격리되어진 공기는 팽창라인(C)을 통해서 개방식 팽창탱크(2)로 배출되어, 열교환기(1)에 난방수가 충진되게 된다.In more detail the start operation of the boiler, if the boiler is operated while the manual valve 30 for air discharge of the heating line B is opened, the low water level is detected from the low water level sensor 50 (at the time of initial start-up operation. Since the heating line B and the heat exchanger 1 are not filled with heating water}, the solenoid valve 10 is opened while the boiler is not ignited, and the cold water from the heating water replenishment line A is While being supplied to the heat exchanger 1 and the heating line B connected thereto, most of the remaining air is discharged through the air discharge manual valve 30. On the other hand, when the heating water is replenished to the heating outlet part B1 of the heat exchanger 1, the air from the heating outlet part B1 of the heat exchanger 1 to the expansion line connection part is isolated from the upper part of the heat exchanger 1. Although it cannot be discharged to the air discharge manual valve 30 of the heating line B, the first check valve 43a of the pressure regulating valve 40 is opened by the water supply pressure from the heating water supplement line A, The air isolated at the upper part of the heat exchanger 1 is discharged to the open expansion tank 2 through the expansion line C, and the heat exchanger 1 is filled with heating water.
따라서, 작업자는 보일러를 시동운전시켜서 에어배출용 수동밸브(30)로부터 난방수가 흘러나오는 것을 확인한 후에 보일러의 점화를 확인하고 시동운전을 정지시키면 된다.Therefore, the operator may start the boiler and check the ignition of the boiler after confirming that the heating water flows out of the air discharge manual valve 30, and then stop the starting operation.
그러나, 상기 종래 기술에 따르면, 난방수 보충라인(A)의 급수압력이 큰 경우에는 보일러 상부에 잔류된 공기가 만족스럽게 외부로 배출되지만, 난방수 보충라인(A)의 급수압력이 작은 경우에는 보일러 상부에 잔류된 공기가 외부로 배출되지 못하게 되어, 보일러가 가동되지 않게 되거나, 잔류공기로 인해서 난방효율이 저하되는 문제가 발생된다.However, according to the prior art, when the water supply pressure of the heating water supplementation line (A) is large, the air remaining in the upper portion of the boiler is discharged to the outside satisfactorily, but when the water supply pressure of the heating water supplementation line (A) is small Since the air remaining on the upper portion of the boiler is not discharged to the outside, the boiler is not operated, or the heating efficiency is deteriorated due to the residual air.
이를 보다 상세히 설명해 보면, 난방수 보충라인(A)의 급수압력이 압력조절밸브(40)의 제1체크밸브(43a)를 탄발지지하는 스프링(43c)의 복원력보다 큰 경우에는 팽창라인(C)을 통한 팽창탱크(2)로의 잔류공기배출이 만족스럽게 수행되지만, 난방수 보충라인(A)의 급수압력이 이 스프링(43c)의 복원력보다 작은 경우에는 보일러를 장시간 시동운전시키더라도 제1체크밸브(43a)가 닫힌상태를 유지하게 되므로, 팽창라인(C)을 통한 팽창탱크(2)로의 잔류공기배출이 이루어지지 않게 된다. 이러한 경우, 저수위센서(50)로부터 저수위감지신호가 연속적으로 보일러의 작동을 제어하는 제어수단(도시안됨)으로 입력되므로, 보일러의 점화가 이루어지지 못하게 된다. 한편, 난방수 보충라인(A)의 급수압력의 일시적인 상승으로 인해서 압력조절밸브(40)의 제1체크밸브(43a)가 짧은 시간동안 열렸다가 닫히게 되면, 열교환기(1)의 난방출수부(B1)로부터 팽창라인 연결부까지의 잔류공기중 일부분이 팽창라인(C)을 통해서 팽창탱크(2)로 배출되게 되는데, 이러한 경우에는 열교환기(1) 상부의 잔류공기가 배출되지 않은 상태에서 저수위센서(50)로부터의 저수위감지신호가 차단되므로, 상기 제어수단에 의해 보일러의 점화가 이루어지지만, 잔류 공기에 의해서 난방효율이 저하되고, 난방라인(B)과 열교환기(1)의 부식이 촉진되어 제품수명이 짧아지게 된다.In more detail, when the water supply pressure of the heating water replenishment line (A) is greater than the restoring force of the spring (43c) for supporting the first check valve (43a) of the pressure control valve (40), the expansion line (C) Although residual air is discharged to the expansion tank 2 through the gas satisfactorily, the first check valve even when the boiler is started for a long time when the water supply pressure of the heating water supplement line A is smaller than the restoring force of the spring 43c. Since 43a is kept closed, residual air is not discharged to the expansion tank 2 through the expansion line C. In this case, since the low water level detection signal from the low water level sensor 50 is continuously input to the control means (not shown) for controlling the operation of the boiler, the ignition of the boiler cannot be made. On the other hand, when the first check valve 43a of the pressure regulating valve 40 is opened and closed for a short time due to the temporary increase in the water supply pressure of the heating water replenishment line A, the heating outlet part of the heat exchanger 1 ( A part of the residual air from B1) to the expansion line connection part is discharged to the expansion tank 2 through the expansion line C. In this case, the low water level sensor in the state where the residual air on the heat exchanger 1 is not discharged. Since the low water level detection signal from 50 is blocked, the ignition of the boiler is effected by the control means, but the heating efficiency is reduced by the residual air, and the corrosion of the heating line B and the heat exchanger 1 is promoted. Product life will be shortened.
이에 본 발명은 상기와 같은 문제를 해소하기 위하여 발명된 것으로, 보일러 시동운전시 난방수 보충라인의 급수압력에 관계없이 열교환기내의 잔류공기가 용이하게 배출되도록 하여, 잔류공기로 인한 보일러의 작동정지나, 난방효율의 저하가 방지되도록 하는 보일러의 에어배출방법과, 이에 따른 에어배출구조를 제공함에 그목적이 있다.Therefore, the present invention was invented to solve the above problems, and it is possible to easily discharge the residual air in the heat exchanger regardless of the water supply pressure of the heating water replenishment line during the start-up operation of the boiler, thereby stopping the operation of the boiler due to the residual air. It is an object of the present invention to provide an air discharge method of the boiler and an air discharge structure according to it, so that the deterioration of heating efficiency is prevented.

본 발명에 따른 보일러의 시동운전을 보다 상세히 설명해 보면, 난방라인(B)의 에어배출용 수동밸브(30)를 오픈시킨 상태에서 보일러를 가동시키면, 저수위센서(50)로부터 저수위가 감지되므로, 보일러가 점화되지 않은 상태를 유지하면서 솔레노이드밸브(10)가 오픈되어, 난방수 보충라인(A)으로부터의 냉수가 열교환기(1)와 이에 연통된 난방라인(B)으로 공급되면서, 잔류된 공기의 대부분은 에어배출용 수동밸브(30)를 통해서 배출된다. 한편, 열교환기(1)의 난방출수부(B1)까지 난방수가 보충되면, 열교환기(1)의 난방출수부(B1)로부터 팽창라인 연결부까지의 공기는 열교환기(1)의 상부에 격리되어 난방라인(B)의 에어배출용 수동밸브(30)로 배출되지 못하게되지만, 난방수 보충라인(A)의 급수압력이 제1체크밸브(43a)를 탄발지지하는 스프링(43c)의 복원력보다 큰 경우에는, 난방수 보충라인(A)으로부터의 급수압력에 의해서 압력조절밸브(40)의 제1체크밸브(43a)가 오픈되므로, 열교환기(1)의 상부에 격리되어진 공기는 팽창라인(C)을 통해서 개방식 팽창탱크(2)로 배출되어, 열교환기(1)에 난방수가 충진된다.Referring to the start-up operation of the boiler according to the present invention in more detail, if the boiler is operated in a state in which the manual valve 30 for air discharge of the heating line (B) is opened, since the low water level is detected from the low water level sensor 50, the boiler Of the solenoid valve 10 is opened while the cold water from the heating water replenishment line A is supplied to the heat exchanger 1 and the heating line B in communication therewith. Most of them are discharged through the manual valve 30 for air discharge. On the other hand, when the heating water is replenished to the heating outlet part B1 of the heat exchanger 1, the air from the heating outlet part B1 of the heat exchanger 1 to the expansion line connection part is isolated from the upper part of the heat exchanger 1. Although it cannot be discharged to the air discharge manual valve 30 of the heating line B, the water supply pressure of the heating water replenishment line A is greater than the restoring force of the spring 43c that supports the first check valve 43a. In this case, since the first check valve 43a of the pressure control valve 40 is opened by the water supply pressure from the heating water replenishment line A, the air isolated on the upper portion of the heat exchanger 1 is expanded by the expansion line C. Is discharged to the open expansion tank (2), the heating water is filled in the heat exchanger (1).
반면, 난방수 보충라인(A)의 급수압력이 제1체크밸브(43a)를 탄발지지하는 스프링(43c)의 복원력보다 작은 경우에는, 난방라인(B)의 에어배출용 수동밸브(30)를 통해서 난방수가 배출된 후에, 즉 난방라인(B)과 난방출수부(B1) 이하의 열교환기(1) 내부의 잔류공기가 모두 배출된 후에, 일정시간동안 시동운전되더라도 난방출수부(B1) 위쪽의 잔류공기는 팽창라인(C)을 통해서 팽창탱크(2)로 배출되지 못하게 된다. 따라서, 이러한 경우에는 작업자는 에어배출용 수동밸브(60)를 강제적으로 열어서 열교환기(1) 상부의 잔류공기를 팽창탱크(2)로 배출시키게 된다.On the other hand, when the water supply pressure of the heating water refilling line A is smaller than the restoring force of the spring 43c supporting the first check valve 43a, the manual valve 30 for discharging the air of the heating line B is opened. After the heating water is discharged through, that is, after all of the residual air in the heat exchanger 1 below the heating line B and the heating water outlet B1 is discharged, the heating water outlet B1 is upward even if it is started for a predetermined time. Residual air of the can not be discharged to the expansion tank (2) through the expansion line (C). Therefore, in this case, the operator forcibly opens the air discharge manual valve 60 to discharge the residual air in the upper part of the heat exchanger 1 to the expansion tank 2.
본 발명에 따르면, 난방라인(B)의 에어배출용 수동밸브(30)를 통해서 난방수가 배출되는 것을 확인하여 이를 잠근 후에, 에어배출용 수동밸브(60)를 열어서 열교환기(1) 상부의 잔류공기를 강제적으로 배출시킬 수 있으므로, 보일러의 시동운전시간을 단축할 수 있고, 난방수 보충라인(A)의 급수압력과 무관하게 열교환기(1) 상부의 잔류공기를 외부로 배출시킬 수 있게 되어 잔류공기로 인한 제반 문제들이 해소된다.According to the present invention, after confirming that the heating water is discharged through the air discharge manual valve 30 of the heating line B and locking it, the air valve manual valve 60 is opened to retain the upper portion of the heat exchanger 1. Since the air can be forcibly discharged, the start-up operation time of the boiler can be shortened, and the residual air in the upper part of the heat exchanger 1 can be discharged to the outside regardless of the water supply pressure of the heating water supplement line (A). All problems caused by residual air are solved.
한편, 도 4에 도시된 바와 같이, 저수위센서(50)가 압력조절밸브(40)의 하우징(41)에 일체로 구비되도록 하면, 저수위센서(50)의 설치작업이 상당히 편리하게 되는 잇점이 있다. 이를 보다 상세히 설명해 보면, 열교환기(1)나 팽창탱크(2)에 저수위센서(50)를 설치하는 경우에는, 원통형의 열교환기(1)나 팽창탱크(2)를 드릴링한 후, 저수위센서(50)를 용접하거나 나사산 결합시켜야 하므로 설치작업이 번거롭게 되지만, 압력조절밸브(40)의 하우징(41)에 저수위센서(50)를 일체로 설치하는 경우에는, 하우징(41) 성형시 저수위센서 체결부분을 일체로 형성한 후, 저수위센서(50)를 단지 이 체결부분에 체결시키면 되므로 설치작업이 상당히 편리하게 된다. 또한, 압력조절밸브(40)의 하우징(41)에 저수위센서(50)를 일체로 설치하는 경우에는 열교환기(1)로의 공기유입을 적절하게 차단시킬 수 있는 효과도 기대된다.On the other hand, as shown in Figure 4, if the low water level sensor 50 is provided integrally in the housing 41 of the pressure control valve 40, there is an advantage that the installation work of the low water level sensor 50 is quite convenient. . In more detail, when the low water level sensor 50 is installed in the heat exchanger 1 or the expansion tank 2, after drilling the cylindrical heat exchanger 1 or the expansion tank 2, the low water level sensor ( Since the installation work becomes cumbersome because the welding of 50) or screwing is required, when the low water level sensor 50 is integrally installed in the housing 41 of the pressure control valve 40, the low water level sensor fastening portion when the housing 41 is formed After the integrally formed, only the low water level sensor 50 is fastened to this fastening portion, so the installation work becomes quite convenient. In addition, when the low water level sensor 50 is integrally installed in the housing 41 of the pressure regulating valve 40, an effect of properly blocking the inflow of air into the heat exchanger 1 is also expected.
이상 상기한 바와 같은 본 발명에 따르면, 에어배출라인에 설치된 에어배출용 수동밸브의 조작에 의해 열교환기의 난방출수부 상부에 잔류된 공기가 에어배출라인을 통해서 강제적으로 팽창탱크로 배출되므로, 보일러 시동운전시 난방수 보충라인의 급수압력에 관계없이 열교환기내의 잔류공기가 용이하게 배출되어, 잔류공기로 인한 보일러의 작동정지나, 난방효율의 저하가 방지되는 효과가 있다.According to the present invention as described above, since the air remaining in the upper portion of the heating exit portion of the heat exchanger by the operation of the manual valve for air discharge installed in the air discharge line is forcibly discharged to the expansion tank through the air discharge line, the boiler Regardless of the water supply pressure of the heating water replenishment line during the start-up operation, residual air in the heat exchanger is easily discharged, thereby preventing the operation of the boiler due to the residual air and reducing the heating efficiency.
