Drawing Hydraulic Circuits

Shows step-by-step how to draw a hydraulic circuit.

Before you begin

You want to draw a hydraulic circuit in your pipe network.

Requirements:

You have already drawn in the supply and return pipes.

Note:

The installation of the hydraulic circuit is shown here using the example of a mixing circuit.

Navigate to:

Project tabDiscipline Heating2D/3D - Floor planning // 2D - Scheme planningCreate tabCommand group Symbols / Components

Procedure

  1. Click on the button Hydraulic circuits ....

    The dialog Hydraulic circuits opens.

  2. Use the drop-down list to select the desired circuit, e.g. a Mixing circuit.
  3. Use the radio buttons to select whether a three-way control valve, a three-way valve or a three-way stopcock should be used.
  4. Select whether the control valve should be installed on the supply.
    Note:

    Depending on the selected circuit type, you can insert additional components (actuator for the mixing valve, throttle valve for constant admixture, backflow preventer for injection circuit, etc.).

  5. Optional: Press the arrow buttons / to display the function of the selected circuit.
    Note: The mass flow is displayed in percent and the temperature change of the lines is shown in color.
  6. Click the Draw button and follow the instructions in the command line.
    Note: The drawing process depends on which circuit and which additional components have been selected.
  7. Select the insertion point for the mixing valve in the supply or return pipe.
    Note: Check for information in the command line. The rotation of the mixing valve is corrected automatically.

  8. On the return pipe, select the point at which the bypass pipe to the mixing valve should start.
    Note:

    If the mixing valve has been drawn on the return pipe, the connection point of the bypass pipe is selected on the supply pipe.

    The bypass pipe and the T-piece are inserted automatically. The rotation of the mixing valve is corrected if necessary because the position of the bypass pipe has now been defined.

  9. Select an insertion point for the pump downstream of the mixing valve in the direction of flow.
