Your example works for me if I give preview-latex 2 hints:
1) Don't touch $ in order to keep tikz happy
2) Tell preview-latex that it should render tikzpicture environment.
Then your document would look like this:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage[displaymath,floats,graphics,footnotes,
% textmath %% Don't touch $ %%
]{preview}
\PreviewEnvironment[{[]}]{tikzpicture}
\begin{document}
Text
\[
\begin{tikzpicture}[x=1.5cm]
\node (S1) at (0,1) {$S_1$};
\node (D1) at (1,1) {$D_1 \setminus V_1$};
\node (V1) at (2,1) {$V_1$};
\node at ($(S1.east)!0.5!(D1.west)$) {$\sqcup$};
\node at ($(D1.east)!0.5!(V1.west)$) {$\sqcup$};
\end{tikzpicture}
\]
Text
\begin{tikzpicture}[x=1.5cm]
\node (S1) at (0,1) {$S_1$};
\node (D1) at (1,1) {$D_1 \setminus V_1$};
\node (V1) at (2,1) {$V_1$};
\node at ($(S1.east)!0.5!(D1.west)$) {$\sqcup$};
\node at ($(D1.east)!0.5!(V1.west)$) {$\sqcup$};
\end{tikzpicture}
Text
\end{document}
--8<---------------cut here---------------end--------------->8---
where preview-latex in Emacs looks like this:
Reg. the `textmath' option, this is the description from the manual:
`textmath' will make all text math subject to previews. Since math
mode is used throughly inside of LaTeX even for other purposes,
this works by redefining \(, \) and $ and the `math' environment
(apparently some people use that). Only occurences of these text
math delimiters in later loaded packages and in the main document
will thus be affected.
Best, Arash
