VALVE FOR PREVENTING ENTERING OF FOREIGN MATTER |
摘要 |
PURPOSE:To reliably prevent granular foreign matter from being caught between a valve seat and a valve body by continuously disposing a conical member for preventing entering of foreign matter to be integral with the small-diameter end portion of a valve body. CONSTITUTION:A valve rod 4 is integral with the large-diameter end portion in a conical valve body 6 confronting with a circular valve seat 5 disposed in the boundary between a valve chest 2 and an inflow hole 3. The small-diameter end portion of the valve body 6 is integral with the large-diameter end portion in a conical member for preventing entering of foreign matter having the large-diameter end portion 7 having a diameter D3 which is larger than a diameter D1 of the small-diameter end portion and a little smaller than a diameter D2 of the inflow hole 3. When the large-diameter end portion of the member 8 for preventing entering of foreign matter is put in the inflow hole 3, a small space is formed therebetween, and the small space functions as a filter gap. |
