IrriExpress Add a Block - Help Tutorial

How to Add a Block

Blocks are used to create layouts of emitters or drip lines. Blocks are used to quickly fill a designated area with sprinklers or drip lines. A valve represents the blocks requirements and connects it to the mainline. The pressure and flow in the valve is determined when the hydraulics are run for the selected block.

Block with Solid Set

To create a block, select Block on the Irrigation menu.

Place the valve close to your block. If you know where exactly the valve must be, place it there.

The valve can always be moved to a new position at a later stage.

The Solid Set is normally used when each sprinkler is represented by an emitter node.

The Drip option is used when the emitters are embedded into the pipe.

This part of the example continues with the Solid Set type.

Select your Emitter type by first choosing the Series, then the Model, Nozzle and finally the design pressure that the block will use to do the hydraulics and size the pipes.

To turn your layout counterclockwise or clockwise in 1 degree intervals press the Page Up or Page Down buttons.

To rotate the layout by 45 degrees, use CTRL page up or down.

Once satisfied with your layout, click on the screen to place the layout.

The laterals must now be connected to the valve and it can manually be done by using the regular add pipe option. To do it automatically, use the block menu and select Place.
