Problems solved by technology

[0002] At present, the proportional valves used in fire-fighting foam generators at home and abroad are directly mixed with source water (water provided by fire-fighting pumps or fire-fighting systems). The foaming rate and its foaming multiple, so that the coverage area under the same conditions is reduced, the cost of fire extinguishing is increased, and a lot of manpower and material resources are wasted.

Abstract

The invention discloses a compound mixed proportional valve. The compound mixed proportional valve comprises a shell, a water inlet pipe, a foaming agent conveying pipe, a venturi tube, a mixing box and a mixed liquor conveying pipe, wherein the mixing box is fixed in the shell; the venturi tube horizontally traverses the mixing box and is formed by assembling two parts; a fitting surface positioned in the mixing box is formed between the two parts; a water inlet pipe mounting hole, a foaming agent conveying pipe mounting hole and a mixed liquor conveying pipe mounting hole are formed in the shell; the water inlet pipe stretches into the shell through the water inlet pipe mounting hole to be connected with one end of the venturi tube; the other end of the venturi tube is connected with one end of the mixed liquor conveying pipe; the other end of the mixed liquor conveying pipe stretches out of the shell through the mixed liquor conveying pipe mounting hole; the foaming agent conveying pipe stretches into the shell through the foaming agent conveying pipe mounting hole to be connected with the mixing box; a water inlet branch pipe is mounted between the water inlet pipe and the foaming agent conveying pipe. According to the compound mixed proportional valve, a foaming agent and fire-fighting water are enabled to be uniformly and fully mixed, so that the foam expansion rate of foam concentrate of a low-expansion foam gum is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing equipment, in particular to a mixing proportional valve. Background technique [0002] At present, the proportional valves used in fire-fighting foam generators at home and abroad are directly mixed with source water (water provided by fire-fighting pumps or fire-fighting systems). The foaming rate and its foaming multiple, so that the coverage area under the same conditions is reduced, the cost of fire extinguishing is increased, and a lot of manpower and material resources are wasted. [0003] Therefore, how to solve the above technical problems has become the direction of efforts of those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a compound mixing proportional valve, which can completely solve the disadvantages of the above-mentioned prior art. [0005] The purpose of the present invention is achieved through the foll...
