Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a foam liquid filling and foam proportion mixing device. Background Art

[0002] Foam plugs are important equipment in foam fire extinguishing systems. They are particularly suitable for large-scale fires caused by flammable and combustible liquids. They are often installed in important places such as petrochemical enterprises, refineries, oil storage tank areas, and aircraft hangars. Before the foam plugs are used, the foam in the foam generator will be mixed with water, so a filling foam liquid and foam proportion mixing device is required.

[0003] According to a foam proportioning mixing device disclosed on the patent website (authorization announcement number: CN 220345004U), "a foam proportioning mixing device is described, comprising a sleeve and a foam liquid inlet joint provided on the outer wall of the sleeve. Along the flow direction of the main water flow, a nozzle, a foam liquid inlet adjustment plate and a receiving port are sequentially provided in the sleeve; the large inner diameter end of the nozzle abuts against the end of the sleeve, and the small inner diameter end abuts against the foam liquid inlet adjustment plate. A buffer accommodating space is formed between the outer wall of the nozzle, the inner wall of the sleeve and the foam liquid inlet adjustment plate, and the foam liquid inlet joint is connected to the buffer accommodating space; a plurality of liquid passage holes are provided on the foam liquid inlet adjustment plate, so that the foam liquid passes through the buffer accommodating space and the liquid passage holes in sequence into the receiving port and is mixed with the main water flow in the same direction. In the present utility model, the inlet direction of the foam liquid is changed by the buffer accommodating space, so that the foam liquid and the main water flow are mixed in the same direction, thereby increasing the flow rate of the foam liquid and enhancing the mixing effect of the foam liquid and the main water flow."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is in use, the buffer storage space is used to change the liquid inlet direction of the foam liquid, so that the foam liquid and the main water flow are mixed in the same direction to increase the flow rate of the foam liquid and enhance the mixing effect of the foam liquid and the main water flow. The device needs to adjust the pressure in the tank by observing the index of the pressure gauge. Manual adjustment is very laborious, dangerous, and inconvenient to use. Utility Model Content
