PLUNGER HOUSING FOR A SOLENOID VALVE HAVING A COMPOSITE STRUCTURE OF A MAGNETIC MATERIAL AND A NONMAGNETIC MATERIAL

摘要

PURPOSE: A plunger housing for a solenoid valve is provided to prevent deformation of a housing due to welding heat and to obtain mass production by reducing manufacturing costs and increasing productivity.;CONSTITUTION: A plunger housing for a solenoid valve comprises a nonmagnetic pipe(20), a magnetic pipe(30), and a holder(10). The nonmagnetic pipe comprises a nonmagnetic guide part, a magnetic pipe coupling part, and a holder coupling part. The nonmagnetic guide part is connected to the exterior of a plunger to guide the operation of the plunger and has a first diameter. The magnetic pipe coupling part and the holder coupling part are respectively extended to both ends of the nonmagnetic guide part. The magnetic pipe is coupled to the magnetic pipe coupling part and comprises a magnetic guide part connecting to the nonmagnetic guide part. The holder is coupled to the holder coupling part and opens and closes a valve.;COPYRIGHT KIPO 2012
