TiKz FZA（故障树分析）- 转出门问题（不同页面上的小故障树）

Question

我可以在 Latex 中构建故障树，但是我不知道如何创建这个转出门：

这是我的代码：

\documentclass[11pt,a4paper]{article}
\usepackage[utf8x]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{makeidx}
\usepackage{graphicx}
\usepackage{hyperref}
\usepackage{color}


\usepackage{tikz}
\usetikzlibrary{matrix,calc,circuits,calc,arrows}
\usetikzlibrary{circuits.logic.US} % TiKZ Library for US Logic Circuits.
\usepackage{tikz-timing}
\def\degr{${}^\circ$}

\usepackage{pgf}
\usepackage{verbatim}
\usepackage{siunitx}
\usepackage{amsmath}

\begin{document}

\begin{tikzpicture} 
[
tr/.style={buffer gate US,thick,draw,fill=purple!60,rotate=90,
anchor=east,minimum width=0.8cm},

label distance=3mm,  every label/.style={blue},


event/.style={rectangle,thick,draw,fill=yellow!20,text width=2cm, text centered,font=\sffamily,anchor=north},
edge from parent/.style={very thick,draw=black!70},
edge from parent path={(\tikzparentnode.south) -- ++(0,-1.05cm)-| (\tikzchildnode.north)},
level 1/.style={sibling distance=6cm, growth parent anchor=south,nodes=event},
]

\node (g1) [tr] {}
                child {node (e111) {Fail to close \\ (DLe1)}}
                child {node (e112) {Leak  \\ (DLe2)}}
                child {node (e113) {Shuttle Valve \\ (SHUVe2)}};
   
 \end{tikzpicture}
 \end{document}

然而，我只得到这个：

如果你能帮助我，我会非常高兴！干杯 :)
