Abstract
The utility model discloses a kind of timing heating control system and apply the heat meter calibrating apparatus of this system, by arranging a time relay in parallel with hand switch in former heating control system, can when staff go to the post, automatically switched on power by the time relay and heat, reduce the heating stand-by period, increase work efficiency.
Description
Technical field
The utility model relates to a kind of heating control system, particularly relates to a kind of heating control system for heat meter calibrating apparatus.
Background technology
Current heat meter calibrating apparatus is all manually opened heating system, and artificial opening power during working, after start, sees water temperature condition, manual unlocking heating arrangement.Heat meter calibration water temperature is 50 ± 5 DEG C, the water temperature of calibrating installation attemperater is after naturally cooling a night, water temperature drop is very large, before working in second day, must manually opened heating system, be heated to 50 DEG C of water temperatures and just start inspection table, this heat time is at least more than half an hour, decrease the working time, reduce work efficiency.
Summary of the invention
For solving the problem, the utility model provides a kind of timing heating control system, and the utility model additionally provides a kind of heat meter calibrating apparatus with timing heated system, is automatically switched on power heat by the time relay, reduce the heating stand-by period, increase work efficiency.
The utility model is realized by following technical proposals:
A kind of timing heating control system, comprises the hand switch, temperature controller, the heating furnace silk that are cascaded successively, it is characterized in that, also comprise a time relay in parallel with hand switch, the described time relay is connected with heating furnace silk.
With a heat meter calibrating apparatus for timing heated system, install heating furnace silk in heat meter calibrating apparatus heating zone, described heating furnace silk is connected a temperature controller then a hand switch of connecting; It is characterized in that, described heating furnace silk is also connected a time relay, and the described time relay is in parallel with hand switch.
The described time relay can be in parallel with temperature controller, also can temperature controller series connection.
The utility model by adding a time relay on heating control system, controls the heat time, and such as: working morning 8, arranges timer 7:30 and switch on power, heating to stop heating (heat time puts and the heat time can from Row sum-equal matrix) half an hour.Like this, a working, calibrating installation water temperature just well controls at about 50 DEG C, and working just enters inspection table status, which reduce the heating stand-by period, the Appropriate application working time, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of timing heating control system described in the utility model.
Fig. 2 is the schematic diagram of embodiment 2.
Fig. 3 is the schematic diagram of embodiment 3.
1. hand switches in figure; 2. temperature controller; 3. heating furnace silk; 4. the time relay; 5. heat meter calibrating apparatus heating zone.
Embodiment
The utility model is illustrated in detail further below in conjunction with specific embodiment.
Embodiment 1
As shown in Figure 1, this timing heating control system, comprises the hand switch 1, temperature controller 2, the heating furnace silk 3 that are cascaded successively, and also comprise a time relay 4 in parallel with hand switch 1, the time relay 4 is connected with heating furnace silk 3.When hand switch 1 is opened, by the time relay 4 timing Power-On, heat.Because the time relay is connected in circuit heating process, do not carry out calibration operation, do not need accurately to control temperature, only needing rule of thumb to set the heat time can make heating temperatures to predetermined temperature (about 50 DEG C), so the time relay 4 can be in parallel with temperature controller 2, also can connect.
Embodiment 2
As shown in Figure 2, a kind of heat meter calibrating apparatus with timing heated system, installs heating furnace silk 3 in heat meter calibrating apparatus heating zone 5, and described heating furnace silk 3 is connected a temperature controller 2 then a hand switch 1 of connecting; Described heating furnace silk 3 is also connected a time relay 4, and the described time relay 4 is in parallel with hand switch 1, and the described time relay 4 is in parallel with temperature controller 2.
Embodiment 3
As shown in Figure 3, a kind of heat meter calibrating apparatus with timing heated system, installs heating furnace silk 3 in heat meter calibrating apparatus heating zone 5, and described heating furnace silk 3 is connected a temperature controller 2 then a hand switch 1 of connecting; Described heating furnace silk 3 is also connected a time relay 4, and the described time relay 4 is in parallel with hand switch 1, and the described time relay 4 is connected with temperature controller 2.Compared with embodiment 2, adopt such frame mode, when the time relay 4 control circuit heats, also can precise control of temperature.
Claims (4)
1. a timing heating control system, comprises the hand switch, temperature controller, the heating furnace silk that are cascaded successively, it is characterized in that, also comprise a time relay in parallel with hand switch, the described time relay is connected with heating furnace silk.
2. the heat meter calibrating apparatus with timing heated system, installs heating furnace silk in heat meter calibrating apparatus heating zone, and described heating furnace silk is connected a temperature controller then a hand switch of connecting; It is characterized in that, described heating furnace silk is also connected a time relay, and the described time relay is in parallel with hand switch.
3. the heat meter calibrating apparatus of band timing heated system according to claim 2, is characterized in that the described time relay is in parallel with temperature controller.
4. the heat meter calibrating apparatus of band timing heated system according to claim 2, is characterized in that the described time relay is connected with temperature controller.
