Beschreibung
Zusammenfassung:	Disclosed is a valve apparatus of a urea tank for a vehicle, the valve apparatus configured such that a urea solution injection pipe is flexibly bent and has a float so that a urea injection valve provided at the urea solution injection pipe is prevented from being immersed in the urea solution in the urea tank. Thus, the urea solution can be prevented from being damaged upon freezing in a winter season. Further, when a urea solution is injected, the urea solution injection pipe is straightened by flow pressure of the urea solution such that the float is forced to be immersed in the urea solution in the urea tank, and accordingly the urea solution injection valve is immersed therein. Thus, the urea solution can be efficiently injected into the urea tank.
