Abstract: An examination and test system for nuclear-grade control valve is provided and includes a hermetic first chamber, a base, a guide unit, a winder, a steel cable, and a length measurement device. The hermetic first chamber includes a second chamber for accommodating a control valve. The base is disposed outside the hermetic first chamber. The guide unit is disposed on at least one of the control valve and the base. The winder and the length measurement device are disposed on the base. The steel cable connects with a valve rod of the control valve and extends out of the hermetic first chamber to connect with the winder. The steel cable is wound on the guide unit, wound up by the winder, and thus rendered taut at any time. The length measurement device has a measurement element coupled to the steel cable and displays the displacement of the measurement element.

Abstract: The present invention provides a three-dimensional shock-absorbing device, which comprises a base, a carrying base, and a carrying platform. The carrying base is disposed between the base and the carrying platform. A first elastic member is disposed between carrying base and the base for providing vertical shock-absorbing effect. A first limiting groove and a sliding member are disposed between the carrying platform and the carrying base for providing horizontal shock-absorbing effect. In addition, second elastic members connected to the base are disposed on the periphery of the carrying platform for providing horizontal and vertical shock-absorbing effects concurrently and thus achieving three-dimensional shock-absorbing effects. Moreover, the present invention has more support and less tipping. Besides, it is more durable.
