The frame is as the bottom plate of valve box, compares in the bottom plate of current valve box, and the structural strength of frame is bigger, is difficult to destroy. And the gap of the frame can lead rainwater entering the inner cavity of the valve box to directly leak out, and accumulated water can not appear in the inner cavity of the valve box, thereby avoiding the accumulated water from damaging the loading and unloading valve or the instrument device.
8) According to the tank container provided by the invention, the valve box is installed through the inherent frame, the whole valve box has no connection relation with the tank body, and the installation of the valve box can not generate welding seams on the tank body, so that the structural strength of the tank body is ensured.
9) The tank container provided by the invention has the advantages that the valve box is not welded with the tank body, the assembly of all parts of the valve box can be completed in a part manufacturing workshop, and then the valve box is integrally and directly arranged on the tank box, so that the field installation of the tank body and accessories thereof is avoided, and the modular design and manufacturing are realized. Can dismantle when the valve box breaks down, change and easy maintenance.
While the preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.
