PURPOSE: A water trap for a boiler is provided to improve the coupling force of the water trap, a connection re-circulating pipe, and a bypass pipe using a fixing rib. CONSTITUTION: A water trap(10) for a boiler comprises a connection supply pipe(20), a connection re-circulating pipe(30), a bypass pipe(40), and a fixing rib(50). The connection supply pipe is integrally formed in the water trap. The connection re-circulating pipe is located at one surface of the water trap and is contiguous to the connection supply pipe. The bypass pipe is integrally extended from the connection supply pipe and is coupled to the connection re-circulating pipe. Heating water flows into the bypass pipe depending on the pressure of the connection supply pipe. The fixing rib is extended from one surface of the water trap and integrates the connection re-circulating pipe and the bypass pipe with the water trap. |
