The composition and working principle of the products are emphatically introduced, and the advantages and disadvantages of foam proportion mixing products are analyzed, and the design scheme is considered synthetically. The proportional mixing method suitable for testing and testing of foam generator is put forward. 2. According to different kinds of foam production products and foam spray products, the traditional thinking design mode is broken through. The general design scheme of standard pressure proportional mixing device for testing foam fire extinguishing system products is put forward. The main characteristic parameters (pressure range) of different fire fighting products are compared. Finally, the specification of pressure proportional mixer (DN80 / DN100 / DN150) is determined, the connection mode of the test device is demonstrated, and the selection of optimized parts is carried out, and the concrete design scheme is given. 3.According to the range of working parameters (pressure range) tested by the pressure-type proportional mixing device, The flow range and mixing ratio are calculated and the size of nozzle and orifice plate of foam throttle are determined by theoretical calculation of three kinds of scale mixer (DN80 / DN100 / DN150), which are selected for the designed pressure proportional mixing device. The installation mode, installation distance and pipe size of three kinds of proportional mixer and foam tank were confirmed and calculated. 4. Different types were measured by spectrophotometer method and conductivity method. The relationship curve between absorbency and time and the relationship between conductivity and temperature of foam liquid with different foaming ratio and different mixing ratio were studied, and the measuring method of mixing ratio of foam proportional mixer was studied. The mixing ratio test method suitable for evaluating this research device is selected. 5. The standard pressure proportional mixing device for testing foam fire extinguishing system products uses different kinds of foam liquid in different pressure range. The mixing ratio in different flow range was tested and the main performance and test parameters of the standard pressure proportional mixing device were evaluated.
