[0002] The existing foam proportional mixing system used on fire trucks is a negative pressure foam proportional mixing system. The functions of this type of system are: to start the on-board water pump, The high flow rate of the high-pressure water at the outlet will make the foam pipeline form a vacuum to achieve the purpose of pumping the foam liquid, and it is limited to the internal supply of the car. If the water pump stops working, the system will lose all functions

The invention relates to the fire-fighting equipment field, and especially relates to a positive pressure type foam proportion mixing system; the positive pressure type foam proportion mixing system comprises a master cylinder, a vehicle foam liquid pot, a water pot, a foam pool and a main pump, the master cylinder is communicated to the vehicle foam liquid pot and the water pot, the master cylinder, the vehicle foam liquid pot and the water pot are respectively arranged on a fire fighting truck, the foam pool and the main pump are respectively arranged on the fire fighting truck, an inlet of the main pump is connected to the vehicle foam liquid pot and the foam pool through a pipeline, an outlet of the main pump is respectively connected to a supply pipeline used for supplying foam liquid to other fire fighting trucks and a vehicle delivery pipeline used for transporting self-use liquid, the inlet of the master cylinder is connected to the water pot through the pipeline, and the outlet of the master cylinder is connected to the vehicle delivery pipeline. The invention provides the positive pressure type foam proportion mixing system which can supply the foam liquid to other fire fighting trucks under the condition that self-use foam liquid can be satisfied.
Description
technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a positive pressure foam proportional mixing system. Background technique [0002] The existing foam proportional mixing system used on fire trucks is a negative pressure foam proportional mixing system. The function of this type of system is: to start the on-board water pump, and to form a vacuum in the foam pipeline through the high flow rate of high-pressure water at the outlet of the pump. In order to achieve the purpose of pumping foam liquid, and it is limited to the internal supply of the car. If the water pump stops working, the system will lose all functions. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a positive-pressure foam proportional mixing system that can supply foam liquid to other fire trucks while satisfying its own use of foam liquid. [0004] In order to achi...
