More specifically, the bypass valve for bypassing a part of the heating water supply to the heating return pipe when the pressure of the heating water is higher than or equal to a certain level. The present invention relates to a boiler and a valve assembly integrating a discharge cock for draining heating water to the outside.

보일러는 밀폐된 용기 내의 열매체를 열원에 의해 가열시켜 원하는 지역을 난방하는 장치로, 연료를 연소시키는 버너와 연소된 고온의 연소공기에서 난방수로 열을 전달하는 열교환기로 구성되며, 상기 열교환기에서 고온의 열에 의해 가열된 난방수는 난방배관 내부를 순환함으로써 난방을 수행하는 장치이다.A boiler is a device for heating a desired area by heating a heat medium in a sealed container by a heat source. The boiler is composed of a burner that burns fuel and a heat exchanger that transfers heat from the burned hot combustion air to the heating water. Heating water heated by high temperature heat is a device that performs heating by circulating the inside of the heating pipe.

도 1은 종래의 가스보일러 구성을 보여주는 도면이다.1 is a view showing a conventional gas boiler configuration.

보일러(1)는, 난방수를 순환시키는 순환펌프(10), 상기 순환펌프(10)에 의해 압송된 난방수가 버너(21)에서 발생된 고온의 열과 열교환이 이루어지는 주열교환기(20), 난방가동시에는 난방 공급관(71)으로 난방수를 공급하고 온수사용시에는 급탕열교환기(40)측으로 난방수를 공급하는 삼방밸브(30), 온수사용시 직수를 가열시켜 온수를 공급하는 급탕열교환기(40), 난방환수가 내부에 저장되고 난방수의 압력변화를 흡수하기 위한 팽창탱크(50)가 구비된다. The boiler 1 includes a circulating pump 10 for circulating heating water, a main heat exchanger 20 in which heat exchanged with the high temperature heat generated by the burner 21, and the heating water pumped by the circulating pump 10, is heated. The three-way valve 30 to supply the heating water to the heating supply pipe (71) and the hot water using the hot water heat exchanger (40) when using hot water, the hot water supply heat exchanger (40) to heat the direct water when using hot water, Heating return is stored therein and is provided with an expansion tank (50) for absorbing the pressure change of the heating water.

상기 보일러(1)는 난방소요처(도면에 미도시)가 난방 공급관(71)과 난방 환수관(72)으로 연결되는데, 상기 주열교환기(20)에서 가열된 난방수는 난방 공급관(71)을 통하여 이동하면서 난방소요처에 설치된 난방배관을 통하여 열을 방출하고 난방 환수관(72)으로 환수된다.The boiler 1 has a heating source (not shown) connected to the heating supply pipe 71 and the heating return pipe 72, the heating water heated in the main heat exchanger 20 is connected to the heating supply pipe (71). While moving through, the heat is discharged through the heating pipe installed in the heating source and is returned to the heating return pipe (72).

상기 환수된 난방수는 난방 공급수보다 상대적으로 저온인 상태로서 팽창탱크(50)를 거쳐 순환펌프(10)에 의해 다시 주열교환기(20)에서 열교환에 의해 가열된다.The returned heating water is heated by heat exchange in the main heat exchanger (20) by the circulation pump (10) via the expansion tank (50) at a relatively lower temperature than the heating supply water.

상기 난방 공급관(71)과 난방 환수관(72) 사이에는 연결관(73)과 바이패스밸브(60)가 구비된다. 상기 난방 공급관(71)과 난방 환수관(72) 내부의 난방수 압력이 일정 압력 이상인 경우 상기 난방 공급관(71) 내부의 난방수가 상기 연결관(73) 및 바이패스밸브(60)를 거쳐 상기 난방 환수관(72)으로 공급될 수 있도록 되어 있다.The connection pipe 73 and the bypass valve 60 are provided between the heating supply pipe 71 and the heating return pipe 72. When the pressure of the heating water in the heating supply pipe 71 and the heating return pipe 72 is greater than or equal to a predetermined pressure, the heating water in the heating supply pipe 71 passes through the connecting pipe 73 and the bypass valve 60. It can be supplied to the return pipe (72).

특히 난방 부하가 줄어들어 난방 소요처를 통과하는 난방수 유량이 줄어들게 되면 분배기(미도시)에 설치된 일부 각방밸브(미도시)가 닫혀 난방 공급관(71) 내부의 압력이 상승함과 아울러 소음이 발생하게 된다. 이 경우 상기 바이패스밸브(60)가 열려 난방수 일부를 상기 난방 환수관(72)으로 바이패스시키면 압력 강하와 함께 소음도 줄어들게 된다.In particular, when the heating load decreases and the flow rate of the heating water passing through the heating source decreases, some square valves (not shown) installed in the distributor (not shown) close to increase the pressure inside the heating supply pipe 71 and generate noise. do. In this case, when the bypass valve 60 is opened to bypass a part of the heating water to the heating return pipe 72, the noise is reduced along with the pressure drop.

한편, 보일러(1)에는 공장에서 보일러를 생산, 검사한 후에 출하를 위해 포장하기 전에 보일러(1) 배관 내부의 물을 제거하기 위한 퇴수콕크(80)가 구비된다. 상기 퇴수콕크(80)는 보일러 고장 수리시 보일러(1) 배관 내부의 물을 제거하기 위한 용도로도 사용된다.On the other hand, the boiler (1) is provided with a discharge cock 80 for removing the water in the boiler (1) piping before packing for shipment after production, inspection of the boiler in the factory. The discharge cock 80 is also used for the purpose of removing the water in the boiler (1) piping when repairing the boiler.

이러한 종래의 보일러에 의하면, 바이패스밸브(60)가 보일러(1) 내부에 위치해 있기 때문에 바이패스밸브(60)의 고장시 교환수리가 어렵고, 바이패스밸브(60)와 퇴수콕크(80)가 각각 별도로 구비되어 있어 부품 개수가 많고 이를 연결하기 위한 배관 구조도 복잡한 문제점이 있다.According to the conventional boiler, since the bypass valve 60 is located inside the boiler 1, it is difficult to replace and repair the bypass valve 60 when the bypass valve 60 breaks down, and the bypass valve 60 and the discharge cock 80 are Each of them is provided separately, so there are many parts and there is a complicated problem in the piping structure for connecting them.

본 발명은 상술한 제반 문제점을 해결하기 위해 안출된 것으로, 바이패스밸브와 퇴수콕크를 일체화시킴으로써 부품의 개수를 줄이고 배관 구조를 단순화시킬 수 있는 퇴수콕크가 일체화된 바이패스밸브를 구비한 보일러 및 밸브조립체를 제공하고자 함에 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, the boiler and the valve having a bypass valve integrated with the discharge cock that can reduce the number of parts and simplify the piping structure by integrating the bypass valve and the discharge cock.
