The observation window assembly can be stably and fixedly arranged on the box body through the framework bosses and the box body bosses.

Preferably, still be equipped with the seal groove on the outer wall of cavity skeleton, the seal groove is located the below of skeleton boss, is equipped with the sealing washer in the seal groove. The sealing ring plays a sealing role in the whole expansion water tank.

Preferably, the observation hole is a threaded through hole, so that the observation window assembly and the box body can be conveniently detached and installed.

Preferably, the outer wall of the lower part of the hollow framework is provided with a thread matched with the thread through hole, and the hollow framework is connected with the box body through the thread.

Preferably, the installation fluting is equipped with at the top both ends of cavity skeleton, and the installation fluting sets up along the top central line of cavity skeleton, and the dismantlement and the installation between observation window assembly and the box of being convenient for.

Preferably, the top of the inner wall of the hollow framework is in a conical structure, and the function is to enlarge the observation range.

Preferably, the filling component is made of polycarbonate materials, the materials are transparent materials, the liquid level height in the box body can be observed, and the phenomenon of liquid hanging is avoided.

The opaque expansion water tank with the observation window assembly provided by the invention has a stable structure, can not only resist high temperature and high pressure, but also accurately observe the liquid level height in the tank body, avoids the phenomenon of liquid hanging, and has good observability and practicability.
