Description

Technical Field

[0001] This utility model relates to the field of automatic fire extinguishing technology, specifically to an interconnecting pipe fitting for an automatic fire extinguishing box for an electrical cabinet and a perfluorohexanone storage tank. Background Technology

[0002] The perfluorohexanone (PFH) storage tank interconnection fitting for the automatic fire extinguishing box of the electrical cabinet is a key component connecting multiple storage tanks. It is used to achieve balanced distribution and coordinated supply of the extinguishing medium. It is made of corrosion-resistant alloy material, adapted to the chemical properties of PPH, to ensure no leakage during long-term storage. The fitting includes one-way valves, tee / four-way connectors, etc., and can be quickly assembled through standardized interfaces. It can flexibly combine multiple tank systems according to the internal layout of the cabinet. During operation, the fitting ensures that the pressure of each tank is synchronized. When the fire is triggered, PPH is efficiently released through a unified pipeline, improving the fire extinguishing coverage and response speed, and adapting to the fire safety requirements of electrical cabinets with different power ratings.

[0003] Chinese Utility Model Patent Publication No. CN218890088U discloses a perfluorohexanone fire extinguishing device integrating detection and discharge. The specification of this device states that it occupies little space, with the storage cabinet installed outside the distribution cabinet and the closed-type sprinkler head installed inside. The closed-type sprinkler head occupies minimal space and does not affect the use of the distribution cabinet. It also boasts a fast response speed; when the smoke sensor detects smoke inside the distribution cabinet, it transmits a signal to the control box, which opens the solenoid valve and simultaneously triggers the electric initiator to detonate the glass inside the closed-type sprinkler head, quickly opening it to discharge perfluorohexanone extinguishing agent to extinguish the fire. However, this integrated detection and discharge perfluorohexanone fire extinguishing device lacks an installation structure for interconnecting pipes, making it inconvenient to maintain or replace after prolonged use. Furthermore, the lack of a sealing structure makes perfluorohexanone leakage likely, resulting in low sealing performance and poor practicality, hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an interconnecting pipe fitting for an automatic fire extinguishing box and perfluorohexanone storage tank in an electrical cabinet.
