Abstract: PURPOSE: A globe valve for preventing backflow using a check valve with springs is provided to block backflow of fluid without installing an additional valve and to remove a backflow blocking part if a backflow preventing function is not necessary. CONSTITUTION: A globe valve for preventing backflow using a check valve with springs comprises a backflow blocking part(100) and a valve guide(200). The backflow blocking part is mounted under the valve seat to block backflow and comprises a check valve(110) and multiple springs(130). The check valve is mounted at the bottom of the valve seat One end of the spring is connected with the check valve and the other end thereof is connected to the valve guide. The valve guide forms a cap of the globe valve.
