Abstract

The invention provides a winter anti-freezing and emergency system and method used for workshop fire hoses. The system is installed in each water supply houses. The system includes a manual bypass system and an electric bypass system. The electric bypass system includes a first manual stop valve (15), a water inlet electric valve (11), a pipeline valve (12), a water outlet electric valve (13) and a first check valve (14). The manual bypass system includes a second manual globe valve (16), a second check valve (17) and a third manual check valve (18). The first manual check valve (15) is connected with a new water main pipeline and is then connected with water inlet electric valve (11), the pipeline pump (12), the water outlet electric valve (13) and the first check valve (14) successively. The second bypass check valve (16) is connected with the main water inlet pipe and is then connected with a second check valve (17) and a third manual globe valve (18) successively. The third manual globe valve (18) is connected with the main water inlet pipe of a fire hydrant.

Description

technical field [0001] The invention relates to the field of antifreeze technology for fire-fighting water pipelines, in particular to a winter antifreeze and emergency system and method for fire-fighting water pipelines in factory buildings. Background technique [0002] When the northern region is about to enter winter, the fire water pipelines of the steel plants need to be antifreeze. Usually, the whole pipeline is wrapped with insulation material, so as to achieve the effect of heat preservation and antifreeze. However, water does not flow throughout the pipeline. Even if a layer of thermal insulation material is wrapped outside the water pipeline of the factory building, it cannot completely resist the continuous severe cold, causing the danger of partial freezing and cracking of the pipeline. As the temperature gradually rose, the frozen water in the pipes began to melt. Since the pipes are wrapped by the insulation layer, it is not easy to find the cracks due to fr...
