Abstract
The utility model discloses a thermostat for a tank truck pipeline. The thermostat for the tank truck pipeline comprises the pipeline led out from the interior of a tank truck body and a temperature controller. The pipeline is wrapped by a heat preservation layer, and a constant-power heat tracing belt is arranged in the pipeline. The outer wall of the front end of the pipeline is wrapped with a temperature sensing bulb, and the temperature controller is electrically and respectively connected with the constant-power heat tracing belt and the temperature sensing bulb. The thermostat for the tank truck pipeline is simple in structure, the temperature sensing bulb measures the temperature variation of the tank truck pipeline at any time and transmits temperature variation signals to the temperature controller in due time. The temperature controller enables the constant-power heat tracing belt to automatically work according to the set temperature, and therefore liquid media in the tank truck pipeline can be in a constant-temperature state all the time. Due to the heat preservation layer, heat losses of the pipeline are avoided, and the working frequency of the constant-power heat tracing belt is lowered.
Description
Technical field
The utility model relates to tank truck field, specifically a kind of tank truck pipeline constant temperature device.
Background technique
Tank truck pipeline is a kind of passage of carrying fluid, and fluid comprises all kinds of chemical mediums, water and food liquid etc., and pipeline is shorter and trend is simple can all kinds of fluids of more convenient conveying.
In prior art, carry the tank truck pipeline of fluid, on the one hand, very cold winter in northern China, easily the flowing medium in pipeline is frozen, cause the tank truck pipeline can not discharging, on the other hand, temperature in tank truck pipeline is too low easily makes food liquid generation mass change, even if tank truck pipeline outside has thicker thermal insulation layer can not meet as the requirement of the media such as milk to temperature.
Model utility content
The purpose of this utility model is to provide a kind of tank truck pipeline constant temperature device, permanent power heating tape work liberated heat carries out tracing thermal-insulating to pipeline, under the control of temp controller, in the time that pipe temperature is too high, permanent power heating tape stops companion's heat, in the time that pipe temperature is too low, permanent power heating tape starts companion's heat, thereby reaches in the cold area tank truck pipeline object in temperature constant state all the time.
The technical solution of the utility model is as follows:
A kind of tank truck pipeline constant temperature device, include the pipeline from drawing in tank truck tank body, it is characterized in that: the outer wrap of described pipeline has thermal insulation layer, in pipeline, be provided with permanent power heating tape, on the front end outer wall of pipeline, be enclosed with temperature-sensitive bag, include temp controller, described temp controller is electrically connected with permanent power heating tape and temperature-sensitive bag respectively.
Described tank truck pipeline constant temperature device, is characterized in that: the material of described thermal insulation layer is glass fibre or rock wool.
The beneficial effects of the utility model:
The utility model is simple in structure, temperature-sensitive bag is measured at any time tank truck pipe temperature and is changed, temperature variation signal is passed to temp controller in good time, temp controller allows permanent power heating tape automatic operation according to setting temperature, thereby make the interior liquid medium of tank truck pipeline all the time in temperature constant state, thermal insulation layer has been avoided pipeline heat loss, has reduced the work frequency of permanent power heating tape.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of tank truck pipeline constant temperature device, include the pipeline 2 from drawing in tank truck tank body 1, the outer wrap of pipeline 2 has thermal insulation layer 3, in pipeline 2, be provided with permanent power heating tape 4, on the front end outer wall of pipeline 2, be enclosed with temperature-sensitive bag 5, include temp controller 6, temp controller 6 is electrically connected with permanent power heating tape 4 and temperature-sensitive bag 5 respectively.
In the utility model, the material of thermal insulation layer 3 is glass fibre or rock wool.
Permanent power heating tape 4, temperature-sensitive bag 5 and temp controller 6 provide power supply by main car storage battery, in the time that the liquid medium in pipeline 2 raises as milk temperature, heated liquid in temperature-sensitive bag 5 expands, temperature-sensitive bag 5 output temperature signals are to temp controller 6, in the time that temperature exceedes setting temperature, contact switch in temp controller 6 just disconnects automatically, cuts off the electricity supply, and permanent power heating tape 4 stops companion's heat.Now, the temperature of temperature-sensitive bag 5 slowly reduces, when temperature is during lower than setting temperature, temperature-sensitive bag 5 again output temperature signal to temp controller 6, contact switch in temp controller 6 is automatically closed again, recovers power transmission, and permanent power heating tape 4 starts to rework, liquid medium in pipeline 2, as the milk temperature temperature in setting all the time, has reached temperature constant state like this.
Claims (2)
1. a tank truck pipeline constant temperature device, include the pipeline from drawing in tank truck tank body, it is characterized in that: the outer wrap of described pipeline has thermal insulation layer, in pipeline, be provided with permanent power heating tape, on the front end outer wall of pipeline, be enclosed with temperature-sensitive bag, include temp controller, described temp controller is electrically connected with permanent power heating tape and temperature-sensitive bag respectively.
2. tank truck pipeline constant temperature device according to claim 1, is characterized in that: the material of described thermal insulation layer is glass fibre or rock wool.
