Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher detection equipment, in particular to a device that realizes a liquid bath function by utilizing a program-controlled constant temperature box. Background Art

[0002] Water-based fire extinguishers, primarily composed of surfactants and other substances mixed with treated purified water, exist in liquid form, hence the name "water-based fire extinguisher." After spraying, a water-based (water mist) fire extinguisher forms a mist that instantly evaporates a significant amount of heat from the fire, rapidly reducing the temperature and suppressing heat radiation. The surfactant quickly forms a film on the surface of the combustible material, isolating it from oxygen, achieving both cooling and isolation while simultaneously extinguishing the fire, achieving rapid fire extinguishing.

[0003] Typically, when water-based fire extinguishers are sent for inspection or in routine production, it is necessary to determine the freezing point of the extinguishing agent. This is especially true when a new supplier of extinguishing agent is introduced. Accurately determining the freezing point of the extinguishing agent is crucial to determining whether the extinguisher is qualified. Existing testing equipment has a single function and can only perform measurements according to a single standard. It is not compatible with tests of two standards at the same time, and the temperature of the testing equipment cannot be kept constant, which affects the test results. Utility Model Content

The present invention can be compatible with detections of different standards at the same time, and by providing the high and low temperature constant temperature box 1, the temperature of the liquid bath solution is kept constant, and the detection effect is accurate.

[0028] It's worth noting that the bath circulation cup is the core component of this device and can be designed in various sizes to accommodate the simultaneous testing of multiple samples. If necessary, insulation can be added to the bath circulation cup and tubing to prevent excessive temperature fluctuations in the bath solution.

[0029] Specifically, as shown in the figure, a second test tube plug sleeve 8 for sealing the mounting hole is provided on the circumference of the large test tube 9, and a third test tube plug 10 for sealing the test tube opening is provided on the circumference of the small test tube 11.

[0030] Specifically, as shown in the figure, a soft wire temperature probe hole 17 is provided on the circulation cup cover 7, and a soft wire temperature probe 15 is provided on the soft wire temperature probe hole 17 for extending into the liquid bath circulation cup 6 to sense the temperature of the liquid bath solution.

The metal container 2 is connected to the input end of the liquid pump 4 through a first liquid pumping tube 3, and the output end of the liquid pump 4 is connected to the liquid inlet hole 19 of the liquid bath circulation cup 6 through a second liquid pumping tube 5. The reflux hole 20 of the liquid bath circulation cup 6 is connected to the metal container 2 through a reflux pipe 16.

[0032] Specifically, as shown in the figure, the first liquid extraction pipe 3, the second liquid extraction pipe 5, and the return pipe 16 are all low-temperature resistant pipes.

[0033] Specifically, as shown in the figure, the liquid inlet hole 19 is provided on the lower side of the liquid bath circulation cup 6 , the reflux hole 20 is provided on the upper side of the liquid bath circulation cup 6 , and a fixing hole 18 is provided on the bottom side of the liquid bath circulation cup 6 .

[0036] Specifically, the specific implementation principle of the utility model is:

[0037] Connect the metal container to the bath circulation cup assembly, place it in the thermostat, and fill it with the appropriate bath solution. Choose a low-temperature, non-freezing liquid with a high specific heat, such as calcium chloride solution, ethanol solution, or silicone oil. Set the thermostat to the desired temperature and start the pump. The bath circulation cup's inlet is located on the side of the cup. As the solution is pumped in, it rotates inside the cup, ensuring a uniform temperature within the cup and consistent temperatures at different depths. Observe the thermometer reading. When the bath solution reaches the set temperature, add a test tube. The small test tube contains the test fluid, while the larger test tube is placed depending on the test standard. An armored temperature probe monitors the temperature of the test fluid in the tube in real time. Some standards require the critical temperature at which the test solution is completely melted after freezing, while others require the critical temperature at which the test solution is completely frozen. Depending on the test requirement, the real-time temperature measured by the armored temperature probe can be used to determine the corresponding freezing point. The utility model can accurately detect the freezing point of the fire extinguishing agent in strict accordance with different standard requirements, is simple to operate, and can be used with existing equipment to perform high-accuracy freezing point measurement at a relatively low cost.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
