Automatic active volumetric flask group and standby volumetric flask group conversion device of automatic gas fire extinguishing system

Abstract

The present invention discloses an automatic active volumetric flask group and standby volumetric flask group conversion device of an automatic gas fire extinguishing system. The device comprises an active volumetric flask group, a standby volumetric flask group and a conversion control unit. The active volumetric flask group and the standby volumetric flask group respectively comprise a start bottle and a fire extinguishing agent storage bottle. Output interfaces of the start bottles are connected with electromagnetic valves and check valves. The conversion control unit comprises a fire disaster alarming controller, a start bottle conversion switch and a gas control conversion valve. The output terminal of the fire disaster alarming controller is connected with the triggering input terminal of the start bottle conversion switch. The normally closed contact of the start bottle conversion switch and the normally opened contact of the start bottle conversion switch are respectively connected with the input terminals of the electromagnetic valves in the active volumetric flask group and the standby volumetric flask group. The check valves in the active volumetric flask group and the standby volumetric flask group are respectively connected with the gas inlet hole of the start bottle conversion switch and the corresponding interface of the gas control conversion valve. The gas inlet hole of the start bottle conversion switch is connected with the corresponding interface of the gas control conversion valve. With the present invention, the function of automatic conversion of thestandby volumetric flask group is achieved.

Description

technical field [0001] The invention relates to an automatic gas fire extinguishing system, in particular to an automatic switching device for active and standby measuring bottle groups of the automatic gas fire extinguishing system. Background technique [0002] According to Article 3.1.7 of GB50370-2005 "Code for Design of Gas Fire Extinguishing System", "If the storage device of the fire extinguishing system cannot be refilled within 72 hours to resume work, the reserve capacity shall be set according to the standard requirements of 100% of the original storage capacity of the system". Spare set of measuring bottles. In practical application, after the fire extinguishing agent of the active bottle group is released, the putting into work of the spare measuring bottle group is carried out by personnel conversion. There are following disadvantages in this operation method of manual conversion; [0003] 1. It cannot be protected in time. Most of the spare measuring bottle ...

AI Technical Summary

Problems solved by technology

[0003] 1. It cannot be protected in time. Most of the spare measuring bottle groups are equipped with more important protection places. The required protection level is higher, and no leakage protection space is allowed. holidays;

[0004] 2. It needs to be operated by professionals. The conversion of the spare measuring bottle group must have the professional knowledge of starting electrical signals and gas-driven conversion. The professional knowledge is relatively strong. Non-fire professionals cannot trust the appeal operation.
