Libraries:
Simscape / Fluids / Isothermal Liquid / Valves & Orifices / Hydromechanical Valves

Description

The Hydromechanical Valve Interface (IL-PB) block splits the signal from a hydromechanical valve block into the base nodes valve_body, spool, and fluid.

Examples

New

Hydromechanical 3-Way Directional Valve with Position Input

Build a 3-way directional valve using components from the Hydromechanical Valves library and compares it to the behavioral 3-Way Directional Valve (IL) block.

• Open Live Script

New

Hydromechanical Poppet Check Valve

Build a check valve with a poppet design using components from the Hydromechanical Valves library and compares it to the behavioral Check Valve (IL) block.

Ports

Conserving

Port_1 — Three-node composite port

hydromechanical valve composite

Hydromechanical valve composite port that connects to a hydromechanical composite signal.

Programmatic Use

Port: R

valve_body — Valve body

position-based translational

Position-based translational conserving port that represents the position and force along the valve body.

Programmatic Use

Port: valve_body

spool — Valve spool

position-based translational

Position-based translational conserving port that represents the position and force along the moving valve element.

Programmatic Use

Port: spool

fluid — Valve fluid

isothermal liquid

Isothermal liquid conserving port that represents the pressure and flow rate of the fluid in the valve.

Programmatic Use

Port: fluid

Parameters

Valve body port (position-based translational) — Option to enable valve body port

on (default) | off

Select this check box to expose the valve_body port.

Programmatic Use

Parameter:	valve_body_port
Values:	"true" | "false"

Spool port (position-based translational) — Option to enable spool port

on (default) | off

Select this check box to expose the spool port.

Programmatic Use

Parameter:	spool_port
Values:	"true" | "false"

Fluid port (isothermal liquid) — Option to enable fluid port

Values:	"true" | "false"

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"SimscapeFluids_lib/Isothermal Liquid/Valves & Orifices/Hydromechanical Valves/Hydromechanical Valve Interface (IL-PB)"

Example: add_block("SimscapeFluids_lib/Isothermal Liquid/Valves & Orifices/Hydromechanical Valves/Hydromechanical Valve Interface (IL-PB)","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
