[0019] The water tank outlet pipe 22 is provided with a water tank outlet valve 4 , the foam liquid outlet pipe 24 is provided with a foam tank outlet valve 7 , the pump inlet pipe 23 is provided with an external water suction valve 17 , and the two-way circulation pipe 26 is provided with a two-way control valve 18 .
[0020] Specifically, a one-way valve and a flow meter 15 are provided on the pump outlet pipeline 25 at the outlet end of the fire pump 2; wherein, by providing the one-way valve on the pump outlet pipeline 25 at the outlet end of the fire pump 2, it can be ensured that when the external water source directly supplies water to the fire cannon 1 at the top of the boom through the two-way control valve 18, no additional impact will be generated on the fire pump 2, and the control logic meets the load requirements of the overall water circuit; the flow meter 15 can realize real-time monitoring of the liquid output supplied by the fire pump 2.
[0021] Specifically, the pump outlet pipeline 25 located between the flow meter 15 and the fire monitor outlet valve 6 is also connected to a water tank filling pipeline 21, which is connected to the inlet of the water tank 19 and is provided with a water tank filling valve 14.
[0022] Specifically, the water tank 19 and the foam tank 20 are also connected to sewage pipelines respectively. The sewage pipeline connected to the water tank 19 is provided with a water tank sewage valve 3, and the sewage pipeline connected to the foam tank 20 is provided with a foam tank sewage valve 8.
[0023] Specifically, the foam liquid outlet pipeline 24 is also provided with a foam cleaning valve 11, a foam metering valve 12, a foam mixing valve 13, and a foam bypass valve 16, and the foam cleaning valve 11 and the foam mixing valve 13 are both connected to the two-way circulation pipeline 26; wherein, the foam metering valve 12 and the foam bypass valve 16 are provided on the foam liquid outlet pipeline 24 between the foam cleaning valve 11 and the foam mixing valve 13, and the foam metering valve 12 and the foam bypass valve 16 are connected in parallel to the foam liquid outlet pipeline 24.
[0024] Specifically, the foam liquid outlet pipeline 24 is also connected to an external foam liquid suction pipeline, and an external foam liquid suction valve 10 is provided on the external foam liquid suction pipeline.
[0025] Combined with the above technical scheme and the attached drawings, the use method and working principle of the utility model are described as follows: (1) When encountering an ordinary fire in a high-rise residential building, first control the arm of the fire truck to lift up, aim the fire monitor 1 at the top of the arm at the fire extinguishing point, and then use the fire pump 2 to pump water. Since the water stock in the water tank 19 and the foam stock in the foam tank 20 are limited, the water tank foam truck is connected to the water tank external water supply valve 5 and the external foam liquid valve 9 respectively, so that water and foam liquid can be continuously injected into the water tank 19 and the foam tank 20, which can ensure that the fire truck has a continuous fire extinguishing source; this fire extinguishing method is called automatic water extinguishing, and its water pumping pressure depends on the pressure of the fire pump 2 of the fire truck. If encountering a fire in a low-rise civil building, one end of the water hose can also be directly connected to the two-way control valve 18 on the two-way flow pipeline 26, and a manual simple water monitor is installed on the other end of the water hose. Turn on the fire pump 2 and the two-way control valve 18, and then turn on the manual simple water monitor to directly extinguish the fire. At this time, the two-way control valve 18 plays a one-way liquid discharge role.
[0026] (2) When a fire occurs in a scene where many fire hydrants are arranged (for example, a fire in a petroleum and petrochemical enterprise), the fire hydrant at the fire extinguishing site can be directly connected to the two-way control valve 18 on the two-way flow pipeline 26. After the fire hydrant is opened, it has a certain water pressure, which can directly drive the fire monitor 1 at the top of the boom to perform fire extinguishing operations. At this time, the two-way control valve 18 plays a one-way liquid inlet role. In this way, the water pressure does not need to be pressurized twice. When the position of the fire extinguishing point at the fire extinguishing site is relatively fixed, the water source can be connected in a relatively simple way to quickly extinguish the fire.
[0027] (3) In addition, when encountering a large fire, first control the arm of the fire truck to lift, aim the fire monitor 1 at the top of the arm at the fire extinguishing point, and then connect the external water suction valve 17 and the external foam liquid valve 10 installed on the pump water inlet pipeline 23 to the water tank foam truck. The fire extinguishing source in the water tank foam truck can be directly sucked in and provided to the fire pump 2, and then the fire extinguishing source provided by the water tank foam truck is ejected by the fire monitor 1 through the fire pump 2. In this way, the input water pressure of the water tank foam truck and the fire pump 2 of the fire truck can be pressurized by its own operation, and secondary pressurization can be performed, which can enable the fire truck to extinguish the fire continuously and effectively. This fire extinguishing method is called coupled water supply fire extinguishing.
[0028] Since the utility model adopts a two-way flow pipeline 26 and a two-way control valve 18 installed thereon, it is possible to directly supply water to the fire monitor 1 at the top of the boom from the external fire hydrant and to directly supply liquid to the manual simple water monitor from the fire pump 2; this saves the installation space of the pipeline, reduces the use of valves, makes the entire fire truck disembarkation design more compact, and also leaves more space for the design and placement of the water tank 19 and the foam tank 20.
[0029] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the embodiments of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
