<p>One objective of the present invention is to provide a boiler including a bypass valve having an integrated drain cork so as to reduce the number of components and simplify a piping structure by integrating the bypass valve with a drain cork. In order to achieve the above described objective, the boiler according to the present invention includes: an integrally formed connection body having an inlet pipe connected to a heating supply pipe so that heating water flows therein, an outlet pipe communicating with the inlet pipe and connected to a heating water return pipe, and a drain pipe communicating with the inlet pipe and the outlet pipe and discharging the water in the boiler to the outside; and a valve module and a drain cork unit, wherein the valve module has a bypass valve unit disposed between the inlet pipe and the outlet pipe allowing the water in the heating supply pipe to bypass to the heating water return pipe when the pressure in the heating supply pipe is at or above a predetermined pressure, and wherein the drain cork unit is inserted into the drain pipe in the state in which the drain cork unit is coupled to the bypass valve unit so as to open or close the drain pipe.</p> |
