Abstract

The invention provides a variable force spring device for a sodium pipe system of a fast reactor. The variable force spring device comprises a top plate, an indicator board assembly, springsin an evennumber, a bolt assembly, a shell assembly and an elastic nut. The top plate is fixedly connected above the shell assembly, the springs are arranged in the shell assembly, the bolt assembly penetratesthe centers of the springs, the upper end of the bolt assembly is connected to the indicator board assembly while the lower end of the bolt assembly is connected to the elastic nut, the indicator board assembly presses the upper ends of the springs, and the springs are arranged in a matrix. The variable force spring device also comprises a tray receiving assembly which is arranged at the middle contact position between the upper and lower springs. By arranging the springs arranged in the matrix, the using strength and the using load of the variable force spring are enhanced, the operating stroke range of the variable force spring device is improved, and the working state of the variable force spring can be understood more intuitively. The variable force spring devicefacilitatesreal-time detection and overload shutdown.

Description

technical field [0001] The invention belongs to the structural design of a spring supporting device, and in particular relates to a variable force spring device used for a fast stack sodium piping system. Background technique [0002] At present, the variable force spring devices on the market are not suitable for supporting the sodium piping system. In the fast stack sodium piping system, the variable force spring device not only needs to support the pipeline, but also needs to support the sodium valve equipment. In the sodium piping system, the filling material of the pipeline is liquid sodium. Sodium is a chemically active alkali metal, so it has certain dangers. Secondly, its temperature is relatively high, 250 ° C to 550 ° C. Therefore, the variable force spring device is required not only to consider its design safety and material specificity. [0003] For example, Chinese patent CN 201836610 U discloses a flange bolt connection type variable force spring support and...
