Embodiment Construction
[0036] The present invention will be further described below in conjunction with accompanying drawing:
[0037] Such as Figure 1-9 As shown, a mixer with an adjustable ratio of foam to liquid based on a Venturi tube includes a Venturi tube 1, a first pipeline 2, a second pipeline 3, a hydraulic film actuator 4, a control valve 5, a bracket 6 and an upper end The adjustment module 7; the upper end adjustment module 7, the hydraulic film actuator 4, the support 6, the control valve 5 and the Venturi tube 1 are connected sequentially from top to bottom. Both ends of the first pipeline 2 are respectively connected to the hydraulic membrane actuator 4 and the Venturi tube 1 , and both ends of the second pipeline 3 are respectively connected to the hydraulic membrane actuator 4 and the control valve 5 .
[0038] The Venturi tube 1 is placed horizontally, one end of the Venturi tube 1 is the water inlet of the fire-fighting water, and the other end of the Venturi tube 1 is the liqu...
