Description

Fire control deluge system of power plant Technical Field The utility model relates to the technical field of deluge systems, in particular to a fire-fighting deluge system for a power plant. Background The fire-fighting deluge system for power plant is an open type automatic water-spraying fire-extinguishing system, which is controlled by a fire automatic alarm system or a transmission pipe, and after the deluge alarm valve is automatically opened and a water supply pump is started, water is supplied to an open type sprinkler head so as to achieve the aim of rapidly extinguishing fire. The system has the characteristics of large water yield and timely fire extinguishment, and is generally used for buildings and parts with rapid fire spread and high risk, such as industrial places like power plants. The fire-fighting rain system installed on the site of the power plant is generally an open system, the installation mode of the rain valve is vertical, the on-line test alarm bell and the alarm device are arranged at vertical positions, when the on-line test alarm bell and the pressure alarm switch are operated, the bottom test ball valve is opened for test operation, after the test is completed, water stored in the pipeline is left in the pipeline, particularly at the corner of the pipeline, corrosion to the pipeline, the valve and the alarm bell is serious, corrosion damage to bearings in the alarm bell often occurs, internal leakage of the valve occurs, and the condition of blockage in the pipeline seriously affects normal and stable operation of the rain valve, so the utility model provides the fire-fighting rain system for the power plant to solve the problems in the prior art. Disclosure of utility model According to the fire-fighting deluge system for the power plant, which is provided by the utility model, the three-way pipe is additionally arranged at the included angle between the first pipeline and the second pipeline and is connected with the drip valve in a matched joint, residual water is discharged through the drip valve after the test is finished, when the test is carried out, the drip valve can be closed by high-pressure water, the test is ensured to be carried out normally, and the rust damage condition of the alarm bell, the valve and the pipeline of the deluge valve is effectively eliminated.
