Autopipe添加安全阀问题

tipinyin

大家有没有用Autopipe的呢，如何用Autopipe模拟安全阀呢？
帮助手册里倒是有一点说明安全阀的内容：

Relief and Angle Valves
Although the function of a relief valve is quite different from that of an angle valve, they are both modeled in the same manner in AutoPIPE. Relief and angle valves are different from other types of valves because the direction of the inlet pipe is at a 90° angle from the outlet pipe. For all other valve types, the inlet and outlet pipes lie along a straight path.

Example


Modeling
When the inlet and outlet pipes do not lie on a straight path, the direction change can be specified using the offset fields on the Valve dialog. Define an ANSI class 300, steel, 8" angle valve in a piping system (the offsets from the inlet face to the outlet face are DX = 11" and DY = -11").

Build a system from A00 to A01 using an 8" standard schedule pipe. The global coordinates for the system points are listed below (length units are feet, and offsets are measured from the preceding point):



Select Insert/Valve  to open the Valve dialog. Specify an ANSI 300 valve to point A02. Begin defining the far end of the valve by entering 1 in the "Length" field, then enter the 0.9167 (ft) offset in the "DX" field, and the -0.9167 offset in the "DY" field as shown. Don't accept the dialog just yet.

When the cursor leaves the "DZ" field, the value in the "Length" field is automatically updated to reflect the length of the valve based on the values in the offset fields. Specify a WN connection type, then press OK to close the dialog.

Note: The "Offset" fields can also be used to define direction cosines, thus requiring the initial length value to be re-specified in order to reflect the direction defined by the cosine values. Refer to Section 4.7 of the User Reference manual for details.

After the Valve dialog has been accepted, a tilted valve is drawn between the near and far end points.

Define a section of pipe coming out of the far end of the valve. The global coordinates for the system point are listed below (length units are feet, and offsets are measured from A02):



It should be noted that a warning will be issued when a global consistency check is performed. The warning states that there are kinks at the near and far end points of the valve (A01 and A02). This is a consequence of the direction change and can be ignored since the direction change is intended.

但是我按这里添加还是不像例子那样的，请教一下各位？
