Description

Technical Field

[0001] The utility model relates to an internal pressure storage fire extinguishing system device, in particular to an internal pressure storage heptafluoropropane fire extinguishing system device. Background Art

[0002] The internal pressure storage fire extinguishing system device refers to a system in which the fire extinguishing agent storage bottle and the driving gas storage bottle are integrated into one, and the fire extinguishing agent is released by internal pressure. Heptafluoropropane is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and has a physical fire extinguishing effect. It belongs to polyfluorinated alkanes. It is colorless, odorless, low-toxic, non-conductive, and does not pollute the protected object. The disadvantage of the existing internal pressure storage system fire extinguishing device using heptafluoropropane as the fire extinguishing agent is that once the fire extinguishing device leaks or has insufficient pressure, and it is impossible to detect it conveniently and quickly, resulting in low practicability of the fire extinguishing device. Summary of the Utility Model

[0010] Advantages of the present utility model:

[0011] The present utility model uses a leakage detection cylinder to detect whether the siphon tube inside the seal detection valve leaks.

[0023] Referring to Figures 1-4 , a preferred embodiment of the present utility model, an internal pressure storage type heptafluoropropane fire extinguishing system device, includes a fire extinguishing tank 1. A siphon tube 6 is arranged in the fire extinguishing tank 1. A seal detection valve 4 is arranged on the siphon tube 6. The seal detection valve 4 includes two valve body frames 5 with the same structure. The bottom of the valve body frame 5 abuts against the top of the fire extinguishing tank 1. A chute 8 is arranged on the valve body frame 5. A sliding plug plate 7 is arranged in the chute 8. A clamping plate 10 is arranged on the sliding plug plate 7. The clamping plate 10 is arc-shaped. The arc of the clamping plate 10 is selected according to the diameter of the siphon tube 6, so that the clamping plate 10 can always clamp the siphon tube 6. A bolt 11 for positioning is arranged on the sliding plug plate 7. A sealing rubber 9 is arranged on the clamping plate 10. A sealing rubber ring is arranged at the connection of the chute 8 and the sliding plug plate 7. The sealing rubber 9 and the sealing rubber ring are used to improve the sealing performance of the seal detection valve 4.

[0024] Specifically, when the present utility model is used, the two valve body frames 5 are placed on both sides of the siphon tube 6. By moving the sliding plug plate 7 to abut against the outer wall of the siphon tube 6, and through the movement of the sliding plug plate 7 and the connection and limitation of the sliding plug plate by the bolt 11, the clamping plate 10 is convenient for clamping siphon tubes 6 of different sizes to detect the sealing performance, improving the applicability of the seal detection valve 4.
