Description:

Hollow Water Injection Allocator belongs control tool used in water well, and it is used with excluder in downhole separate

zone water injection. It is composed of water distribution system and control gear.The model can show its working principle

and composition, and can be trained of unpacking and packing, as well as pipe string assembly according to the criteria.

In water flooding,high-tension water is injected from the upper adapter to the cavity of the lower adapter, then it flows

from the water nozzle of scale sleeve and the exhalant pore of center tube to the cavity of the lower adapter.When water

pressure is bigger than the spring force, the valve and the waterflood path are opened, then water injection is realized by

water injection allocator. The water injection is regulated and controled by water nozzle. When the water flooding is

stopped, the valve is closed by the spring force, and the waterflood path is cut dowm.
