[0021] like Figures 1-4 The diagram shows an independent prefabricated deluge valve assembly box, which includes a deluge valve box 1 and a deluge valve assembly 2 installed in the deluge valve box 1.

[0022] Specifically, the rain valve box 1 adopts a double-layer steel plate sandwiched with an insulation layer 14 structure, and the outer surface is coated with an anti-corrosion coating. Several grounding connection blocks 13 are provided on the outer wall of the rain valve box 1, and the top of the rain valve box 1 has ventilation and moisture-proof holes 12.

[0023] The top and bottom ends of the deluge valve assembly 2 are fixed to the deluge valve housing 1 by mounting brackets 3, so that the deluge valve assembly 2 and the deluge valve housing 1 can be detached.

[0024] The deluge valve assembly 2 is equipped with a signal butterfly valve and a fire pipe interface. The signal butterfly valve includes an outlet signal butterfly valve 9 and an inlet signal butterfly valve 10. The outlet signal butterfly valve 9 is located on the upper side of the deluge valve assembly 2, and the inlet signal butterfly valve 10 is located on the lower side of the deluge valve assembly 2. The fire pipe interface includes an outlet fire pipe interface 6 and an inlet fire pipe interface 7. The outlet fire pipe interface 6 is located at the top of the deluge valve assembly 2, and the pipe opening of the outlet fire pipe interface 6 extends horizontally. Correspondingly, a fire outlet pipe reserved hole 11 is opened at the top of the side of the deluge valve box 1. The inlet fire pipe interface 7 is located at the bottom of the deluge valve assembly 2, and the pipe opening of the inlet fire pipe interface 7 extends downward. Correspondingly, a fire water supply pipe reserved hole 15 is opened at the bottom of the deluge valve box 1. At the same time, a drain pipe reserved hole 16 is also opened at the bottom of the deluge valve box 1.
