Description

Technical Field

[0001] The utility model relates to the technical field of heat measurement, in particular to a calorimeter water channel system and a calorimeter. Background Art

[0002] Currently, oxygen bomb calorimeters on the market are generally designed according to the automatic calorimeter method, using water as the medium to achieve various functions. For example, the inner barrel typically uses water as the medium, in which the oxygen bomb is immersed. The heat of combustion is determined by measuring changes in water temperature. The water in the inner barrel must be consistent throughout each test and must be replaced after each test to ensure a roughly consistent water temperature between tests. The outer barrel is typically a closed water jacket, using water as the medium for temperature control, maintaining a constant outer barrel temperature during the test (isothermal method) or varying with the inner barrel temperature (adiabatic method). The outer barrel water typically circulates and has heating and cooling components for temperature control. Except for replenishing the outer barrel when it is empty or short of water, it is desirable that the circulating water volume remain sealed at all times. The water tank, serving as the water storage unit of the oxygen bomb calorimeter, does not require sealing and is generally open to the atmosphere. Because the inner barrel water must be replaced with each test and the temperature of the inner barrel water rises after the test, to increase testing speed and efficiency, the water tank requires self-circulation and heating and cooling functions. The water tank and the outer barrel are connected by water pipes, water pumps and valves to realize the function of water filling and replenishing the outer barrel; the water tank and the inner barrel are connected by water pipes, water pumps and valves to realize the functions of water filling, draining and quantitative water quantity in the inner barrel.

[0003] In related technologies, such as Figure 1 As shown, multiple types of valves are often required between the water tank 100 and the outer barrel 300. For example, a first pump 01 is provided in the circulation loop of the outer barrel 300 to realize the self-circulation of water in the circulation loop of the outer barrel 300. Then, a second pump 02 and a solenoid valve 03 are provided between the water tank 100 and the circulation loop of the outer barrel 300 to pump the liquid in the water tank 100 into the circulation loop of the outer barrel 300, thereby realizing the liquid supply from the water tank 100 to the circulation loop of the outer barrel 300. In the related art, due to the large number of pumps and valves, installation is inconvenient, cost is high, and control is complex.

[0004] Therefore, how to simplify the structure of the calorimeter water system and reduce costs is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0046] The heat calorimeter waterway system realizes liquid flow through the arrangement of the outer drum circulation pipeline 310, can realize temperature control of the outer drum 300, so that the temperature of the outer drum 300 remains unchanged during the test, or changes along with the temperature change of the inner drum 200. Then, the outer drum power component 320 is arranged on the outer drum circulation pipeline 310, and the outer drum power component 320 is used to drive liquid flow, so as to facilitate the outer drum 300 to control the temperature of the liquid in the outer drum circulation pipeline 310. At the same time, the outer drum isolation water inlet four-way joint 330 is additionally arranged on the outer drum circulation pipeline 310, two connecting ports in the outer drum isolation water inlet four-way joint 330 are connected into the outer drum circulation pipeline 310, and then the other two connecting ports in the outer drum isolation water inlet four-way joint 330 are used for one exhaust and one water replenishment.

[0048] Specifically, when the outer barrel circulation pipeline 310 is in a waterless state, the liquid in the water tank 100 enters the outer barrel circulation pipeline 310 through the fourth connecting port 3322 and flows into the inside of the outer barrel power component 320; after the outer barrel power component 320 is started, the liquid in the water tank 100 enters the third connecting port 3321 through the fourth connecting port 3322, and then flows into the outer barrel power component 320, and then flows to the second connecting port 3312 after passing through the outer barrel 300, the air in the outer barrel circulation pipeline 310 is discharged into the second connecting port 3312, and is discharged from the first connecting port 3311; when the air in the outer barrel circulation pipeline 310 is exhausted, the liquid enters the inside of the outer barrel isolation water inlet four-way 330 from the second connecting port 3312, and since the height of the first connecting port 3311 is located at the highest point of the outer barrel isolation water inlet four-way 330, the liquid entering the inside of the outer barrel isolation water inlet four-way 330 will directly flow into the third connecting port 3321, thereby forming a liquid self-circulation of the outer barrel 300, and the liquid in the water tank 100 no longer flows into the outer barrel circulation pipeline 310;
