Example 1

Referring to fig. 1, in the embodiment of the utility model, a fire sprinkler wet system suitable for low temperature environment, including arranging the reposition of redundant personnel pipeline 4 at the wall crown, water testing device 11 is still installed to reposition of redundant personnel pipeline 4's end, and reposition of redundant personnel pipeline 4 mid-mounting has a plurality of automatic sprinkler head 10, the end of intaking of reposition of redundant personnel pipeline 4 is connected with water charging pipeline 3, and water charging pipeline 3 middle part installs wet-type alarm valve group 9 and circulating pump 7 along the direction of intaking in proper order, be equipped with heating device on the circulating pump 7, water charging pipeline 3 mid-mounting between wet-type alarm valve group 9 and the circulating pump 7 has wet return 5, and the end of intaking of wet return 5 is connected with the water outlet end of reposition of pipeline 4, check valve 6 is still installed.

Example 2

In another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that the wet alarm valve set 9 is electrically connected to the hydraulic alarm bell 8, which further increases the safety of the device.

The utility model discloses, the core is circulating pump 7 (can be assisted by heating device), sets up behind wet-type alarm valve group 9, links to each other each spray pipe end by adding wet return 5 of establishing simultaneously, and wet return 5 passes through essential devices such as check valve 6 and sprays the trunk line and link to each other behind the wet-type alarm valve group, before the circulating pump. When in a normal preparation state, the water in front of the wet alarm valve is unchanged, the water behind the valve clack of the wet alarm valve group 9 is pushed (heated) by the circulating pump 7 to flow at a low speed (various fire-fighting switches are not triggered) to the spraying tail end and passes through the return pipe 5, the check valve 6 and the return pipe to reach the valve clack of the wet alarm valve group 9 and the circulating pump 7, and the water circulates continuously in a pipeline behind the wet alarm valve clack. Because of the standard requirement, the wet alarm valve group 9 is arranged in the room with the environment temperature not lower than 4 ℃, the invention takes the low-speed circulation flow of water as the main part, and the anti-freezing measures of electric heating and anti-freezing solution as the auxiliary part are enough to deal with outdoor and underground garages in most areas of China. The invention can make the fire-fighting wet-type spraying system suitable for outdoor and underground garages without freezing and cracking. The flow speed and the flow of the system are greatly increased by several orders of magnitude in the working state (fire extinguishing), and the check valve is arranged to prevent pressure leakage and backflow of fire-fighting water, so that the whole system is equivalent to a wet spraying system in the working state (fire extinguishing).
