Embodiment 1
[0019] Such as figure 1 Shown, a kind of seawater fire-fighting water rapid switching system comprises water inlet pipe 1, seawater filter 4, water pump device 6, seawater fire-fighting tank 11, fresh water fire-fighting tank 14 and fire-fighting pump house 17, and water inlet pipe is anticorrosion pipeline, prevents The water inlet pipe is corroded by seawater. According to the sequence of seawater inflow, the water inlet pipe is connected to the seawater filter, water pump device, seawater fire tank and fire pump room in sequence. The water pump device can be activated to pump seawater into the water inlet pipe. A third electromagnetic valve 2 is installed at the water inlet. Only when the third electromagnetic valve is opened, the water pump device can successfully draw seawater from the sea. When there is no need for fire-fighting work, the third electromagnetic valve is closed, so that the seawater in the pipeline cannot flow, increasing In order to ensure safety, a press...

The invention relates to a firefighting system, and in particular to a rapid switching technology design for seawater firefighting water. The rapid switching technology design for the seawater firefighting water includes a water inlet pipeline, a seawater filtering device, a water pump device, a seawater firefighting tank, a fresh water firefighting tank and a firefighting pump room, wherein the water inlet pipeline is sequentially connected to the seawater filtering device, the water pump device, the seawater firefighting tank and the firefighting pump room; a first valve is arranged on the water inlet pipeline between the water pump device and the seawater firefighting tank; an air opening valve is arranged on the water inlet pipeline between the seawater firefighting tank and the firefighting pump room; the fresh water firefighting tank is connected to the firefighting pump room through a pipeline; an air closing valve is arranged on a pipeline between the fresh water firefighting tank and the firefighting pump room; a liquid controller is arranged on the fresh water firefighting tank. The rapid switching technology design is simple to operate; the problem of corrosion caused byseawater is solved; and the seawater firefighting water and fresh water firefighting water can be rapidly switched during use.
Description
technical field [0001] The invention relates to a fire-fighting system, in particular to a fast switching system for seawater fire-fighting water. Background technique [0002] Coastalization and large-scale are the existing development trends of oil storage tank farms in my country. With the popularization of large storage tanks of 100,000 or even 150,000 m3, the consumption of fire-fighting water has increased sharply. However, in the island areas of our country, fresh water resources are scarce. Under the situation of a sharp increase in fire-fighting water, fire-fighting water sources have become an urgent problem to be solved. The characteristics of island oil depots provide enterprises with inexhaustible seawater resources under the condition of lack of fresh water. If seawater can be used as fire-fighting water, local materials can be obtained, saving a lot of fresh water resources and fire-fighting pools construction cost. At the same time, compared with fresh wate...
