Abstract
The utility model relates to the field of experiment appliances, in particular to a thermostatic bath. The novel thermostatic bath is characterized in that a mixing propeller arranged in a cavity is changed to a sprayer arranged at the bottom of a left cavity, so that the mixing propeller cannot be damaged to affect the use of the whole thermostatic bath when a thermometer drops off, and the temperature difference and temperature fluctuation are reduced in a bath body of the novel thermostatic bath. The thermostatic bath comprises the bath body, the cavity, a circulation passage, the sprayer, heaters, cooling tubes and a temperature sensing platinum resistor, wherein a partition is arranged in the middle of the bath body and divides the bath body into the left cavity and a right cavity; the temperature sensing platinum resistor is arranged at the bottom of the partition; the heaters and the cooling tubes are arranged in the left cavity; the sprayer is arranged at the bottom of the left cavity; and the circulation passage is arranged at the upper end and the lower end of a part between the left cavity and the right cavity. The thermostatic bath has the benefits that the thermostatic bath is simple in structure and lower in cost, the temperature of a liquid medium in the bath body is uniform and stable, the temperature difference and temperature fluctuation are smaller, and a thermostatic effect is ideal relatively.
Description
Technical field
The utility model relates to the experimental apparatus field, relates in particular to a kind of thermostat.
Background technology
Thermostat be working space take liquid as medium, temperature can be regulated and can constant testing equipment at a certain design temperature.The effect of thermostat is the temperature by liquid medium in the control cell body, so that temperature stabilization, even in the workspace is used for proving temperature meter equitemperature measurement instrument in the workspace.The present employed insulating box generally upper and lower side between two cavitys has circulation canal, middle cavity is as the workspace, and bottom middle chamber, be provided with motor and paddle, thereby reach the purpose of uniform temperature to the circulation of both sides cavity with middle chamber by liquid medium in the cell body.The problems such as it is larger that but this thermostat exists in the cell body maximum temperature difference and temperature fluctuation, and result of use is not ideal enough, and if when test thermometer drop on the paddle, can damage paddle.
Summary of the invention
The utility model is for the prior art above shortcomings, novel a kind of thermostat is provided, paddle setting in the cavity changes left cavity bottom into and is provided with injection apparatus, damage paddle in the time of can avoiding like this thermometer to drop, affect the use of whole thermostat, and the temperature difference and temperature fluctuation diminish in the cell body of novel insulating box.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of thermostat, comprise cell body, cavity, circulation canal, injection apparatus, heater, cooling tube, temperature-sensitive RTD, described cell body middle part is provided with dividing plate, described dividing plate is divided into left cavity, right cavity with cell body, described dividing plate bottom is provided with the temperature-sensitive RTD, be provided with heater, cooling tube in the described left cavity, described left cavity bottom is provided with injection apparatus, and upper and lower end is provided with circulation canal between described left cavity and the described right cavity.
The utility model beneficial effect: simple in structure, cost is lower, in the cell body liquid medium temperature evenly, stable, the temperature difference and temperature fluctuation are less, the constant temperature effect is more satisfactory.
Description of drawings
Fig. 1 is thermostat structural representation described in the utility model.
Among the figure: the 1-cell body; The left cavity of 2-; The 3-circulation canal; The 4-injection apparatus; The 5-heater; The 6-cooling tube; 7-temperature-sensitive RTD; The 8-dividing plate; The right cavity of 9-.
The specific embodiment
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings:
As shown in Figure 1, a kind of thermostat of the present utility model, comprise cell body 1, cavity, circulation canal 3, injection apparatus 4, heater 5, cooling tube 6, temperature-sensitive RTD 7, be provided with dividing plate 8 at cell body 1 middle part, described dividing plate 8 is divided into left cavity 2 with cell body 1, right cavity 9, upper between described left cavity 2 and described right cavity 9, the lower end is provided with circulation canal 3, circulation canal 3 circulates the liquid in left cavity 2 and the right cavity 9, in dividing plate 8 bottoms temperature-sensitive RTD 7 is installed, temperature-sensitive RTD 7 is used for proving temperature, be provided with heater 5 in left cavity 2, heater 5 is used for heating to liquid medium.Also be provided with cooling tube 6 in left cavity 2, cooling tube 6 connects cold-producing medium, is used for lowering the temperature to liquid medium.In left cavity 2 bottoms injection apparatus 4 is installed, injection apparatus 4 adopts jet pump or other the similar devices of selling on the market, and the liquid in the cell body 1 is circulated.
During use, liquid medium adopts water or oil, control cooling tube 6 or heater 5 work by temperature control system according to the temperature that the temperature of setting and temperature-sensitive RTD 7 measure during work, medium is in left cavity 2 interior process high degree of agitation, entering into another cavity is in the right cavity 9 again, so both can create the uniform fluid space of temperature stabilization in the workspace.Two cavitys about the thermostat of utility model will be divided into, with one of them cavity as the workspace, injection apparatus 4, heater 5 and cooling tube 6 are installed in another cavity, be about to right cavity 9 as the workspace, injection apparatus 4, heater 5 and cooling tube 6 are installed in the left cavity 2, form the single cycle of a medium, simple in structure and technical indicator is higher, temperature is more stable and evenly.
