Background
In default configuration of OpenPlant Modeler, there is no tool to place the valve. However, this valve can be placed through a key-in command but it places a normal two port valve instead of three way valve. This article will explain what changes are required to place three way control valve.
Steps to Accomplish
- Launch class editor and load OpenPlant_3D.01.07 schema. This schema is generally located in C:\ProgramData\Bentley\OpenPlantModeler V8i\WorkSpace\Projects\%ProjectName%\Dataset\schemas folder.
- Supplement it with OpenPlant_3D_Supplemental_Modeling.01.07 schema.
- Go to THREE_WAY_CONTROL_VALVE class.
- Locate "Creation Attribute" custom attribute on Class tab.
Draw script used here is inherited from CONTROL_VALVE class which is for 2-port control valves. So we need to modify this attribute so that it places the three way valve. - Go to THREE_WAY_VALVE class. We will copy 'Creation Attribute' from this class and paste it on THREE_WAY_CONTROL_VALVE.
- Right click on this class and select Copy option from context menu as highlighted below.
- Select "Creation Attribute" from this dialog and drop it on the lower section.
- Go back to THREE_WAY_CONTROL_VALVE class and right click, select Paste.
- Creation attribute should look like this.
- Now switch to properties tab and add new property (DESIGN_LENGTH_CENTER_TO_BRANCH_END) as shown below.
- Add "OpenPlant_Physical_Catalogue_Property_Map" custom attribute on this property.
- Right click on EC Expression field and select "Add Element" option.
- Add below expression in EC Expression field.
COMPONENT_TABLE.COMP_LEN / 2 - Save the changes in schema.
- Launch OpenPlant Modeler and apply this key-in command to place three way control valve.
Note: To create tool for this component refer this article How to Add Component as a Tool in Piping Task - Place the valve and connect the pipes to verify the result.
Please Note: Make sure to add the values for PIPE_OD_B field in spec table which denotes the Outside Diameter of Branch Port. It could affect the valve graphics if this field is not added or the values are Null.
