Embodiment Construction
[0019] The core of the present invention is to provide a water diversion system for fire-fighting vehicles, the vacuum gauge of which is not easy to be damaged during positive pressure water supply operation, and the vacuum gauge has higher indication accuracy during self-suction operation. Another core of the present invention is to provide a fire fighting vehicle including the above-mentioned water diversion system.
[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a specific implementation of the water diversion system of the fire fighting vehicle provided by the present invention.
[0022] In a specific embodiment, the water diversion system of the fire-fighting vehicle provided by the present invention...

The invention discloses a water diversion system of a fire-fighting vehicle. The water diversion system comprises a diversion conduit and a vacuum meter for measuring the vacuum degree of the diversion conduit, wherein an automatic protection device is arranged between the vacuum meter and the diversion conduit, and the automatic protection device blocks off the connecting passage between the diversion conduit and the vacuum meter when positive-pressure water is introduced to the diversion conduit. When the positive-pressure water is introduced to the diversion conduit, the vacuum meter is isolated from the positive-pressure water, and therefore the vacuum meter can not be damaged easily even without the positive-pressure, thereby being beneficial to the increase of the service life and the decrease of the service cost of the fire-fighting vehicle. Besides, the positive-pressure range is unnecessary to set for the vacuum meter, and therefore the precision of the negative-pressure range of the vacuum meter is remarkably improved, thereby ensuring the reliable operation of the vacuum meter.
Description
Technical field [0001] The invention relates to the technical field of fire-fighting vehicles, in particular to a water diversion system for fire-fighting vehicles. In addition, the present invention also relates to a fire fighting vehicle including the above-mentioned water diversion system. Background technique [0002] At present, the role of fire fighting vehicles in the rescue and relief process is becoming more and more important. [0003] Fire-fighting vehicles, especially elevating fire-fighting vehicles, often need to deal with various complex site conditions during fire-fighting operations. According to different fire-fighting water sources, the operations that fire-fighting vehicles should be able to complete include self-suction operations, fire hydrant water supply operations, Tanker water supply operation, external foam absorption operation, self-absorption foam operation, etc. [0004] In the process of self-suction operation, etc., negative pressure will appear in t...
