Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a convenient fire extinguishing foam quality detection device, belonging to the technical field of fire extinguishing foam. Background Art

[0002] Fire extinguishing foam is a chemical substance specially designed for fire extinguishing. It is mainly composed of surfactants, stabilizers, preservatives and water. Its main function is to form a layer of covering on the fire source to isolate oxygen, thereby achieving the purpose of suffocating the fire source. In addition, the foam can also cool the fire source by reducing the flame temperature and absorbing the heat of the burning material, further preventing the spread of the fire.

[0003] A Chinese patent publication (publication number: CN219758004U) discloses a low-multiple foam fire extinguishing agent fluidity detection device, including a test bench body and an insulation tank, the test bench body is horizontally arranged, and the insulation tanks are installed at the front and rear positions of one side of the top surface of the test bench body. The beneficial effect is that: the utility model is provided with two insulation tanks on the top of the test bench body to hold the low-multiple foam fire extinguishing agent and the standard reference liquid, and the insulation tanks are installed with a booster assembly and a thermometer to provide a pressure environment inside the insulation tank and to detect the temperature of the low-multiple foam fire extinguishing agent and the standard reference liquid, respectively. After reaching a specific temperature and pressure environment condition, the low-multiple foam fire extinguishing agent and the standard reference liquid are discharged from the discharge pipes of the two insulation tanks within a specified time, and the amount of discharged liquid is counted to obtain the fluidity detection result by intuitive comparison, which replaces the operation mode of measuring the low-multiple foam fire extinguishing agent and the standard reference liquid in sequence;

[0004] The device discharges low-multiple foam fire extinguishing agent and standard reference liquid through the discharge pipes of two insulation tanks within the specified time and calculates the amount of discharged liquid to obtain the fluidity test result. However, it is not convenient to seal the air intake pipe with the external air intake equipment, and air leakage is prone to occur during use, which affects the test results. Therefore, a convenient fire extinguishing foam quality detection device is proposed. Utility Model Content

The tube body 8 is connected with the interior of the second tank body 7, and the end of the first tube body 8 away from the second tank body 7 is connected with the interior of the first tank body 2. Valves are installed on the first tube body 8 and the second tube body 9. A pressure gauge 5 is fixedly installed on the upper surface of the first tank body 2, and a bent pipe 3 is fixedly installed on the upper surface of the first tank body 2, one end of the bent pipe 3 is connected with the interior of the first tank body 2, and a liquid inlet pipe 4 is fixedly installed on the upper surface of the first tank body 2, one end of the liquid inlet pipe 4 is connected with the interior of the first tank body 2. An air inlet pipe 6 is movably sleeved on the end of the bent pipe 3 away from the first tank body 2.

[0025] In one embodiment, the outer fixed sleeve of the curved pipe 3 is provided with a first circular plate 10, and the outer fixed sleeve of the intake pipe 6 is provided with a second circular plate 11. The front side of the second circular plate 11 is in movable contact with the rear side of the first circular plate 10. Two rectangular blocks 13 are fixedly installed on the front side of the second circular plate 11. The two rectangular blocks 13 are symmetrically arranged. The front ends of the two rectangular blocks 13 extend to the front side of the first circular plate 10. The two rectangular blocks 13 are provided with grooves 14 on the sides away from each other. The inner part of the groove 14 is movably provided with limit blocks 15. The two limit blocks 15 are fixedly connected with springs 17 on the sides close to each other. The two springs 17 are fixedly connected with the inner walls of the two sides close to each other on the sides respectively.

[0026] In one embodiment, a sealing ring 12 is fixedly bonded to the inner wall of the air intake pipe 6, and the inner wall of the sealing ring 12 is in active contact with the outer side of the curved pipe 3.
