Device for assembling valve

A device for assembling a valve comprises a special-shaped valve and a worktable, wherein the special-shaped valve comprises a prefabricated cap, a sealing cup, a spacer and a valve spool. A working disk with a motor is arranged on the worktable, the prefabricated cap is conveyed to the upper portion of the working disk through a prefabricated cap feeding rail, the sealing cup is conveyed to the middle of the working disk through a sealing cup feeding rail, the spacer is conveyed to the middle and lower portion of the working disk through a spacer feeding rail, the valve spool is conveyed to the lower portion of the working disk through a valve spool feeding rail, the sealing cup feeding rail, the spacer feeding rail, the valve spool feeding rail and the prefabricated cap feeding rail are circumferentially and sequentially arranged along the working disk, an upper push rod mechanism and a lower push rod mechanism are arranged on the working disk, the upper push rod mechanism is positioned above the sealing cup feeding rail, the lower push rod mechanism is positioned below the valve spool feeding rail, an opening groove for transferring the sealing cup is formed in the working disk, and the sealing cup leaving the sealing cup feeding rail enters the opening groove. The device has the advantages of flexibility in operation and high production efficiency.
