Description of drawings
Fig. 1 is the structural representation of the unburned dried permanent water level thermostat water bath of the utility model.
Among the figure: 1 radiator valve, 2 power supply indicators, 3 water baths, 4 water-bath pallets, 5 power switches, 6 electric heating tubes, 7 liquid level controlled adjusters, 8 water level alarms, 9 level sensors, 10 magnetic valves.
The specific embodiment
As shown in Figure 1, the unburned dried permanent water level thermostat water bath of the utility model is to convert on commercially available digital display thermostat water bath basis, and the digital display thermostat water bath comprises radiator valve 1, power supply indicator 2, water bath 3, water-bath pallet 4, power switch 5, electric heating tube 6.The inventor has increased electronic level at this and has regulated water charging system, namely on radiator valve 1 side of thermostat water bath liquid level controlled adjuster 7 is installed, the power supply indicator 2 other water level alarms 8 of installing at thermostat water bath, level sensor 9 is installed in water bath 3 one sides of thermostat water bath and is linked to each other with liquid level controlled adjuster 7, water bath 3 opposite sides are established magnetic valve 10 and are linked to each other with liquid level controlled adjuster 7.During installation, magnetic valve external laboratory running water pipe or elevated tank (pond).
When water-bath uses, because the continuous evaporation of water, water level descends, the liquid level that the water level signal that this moment, level sensor detected changes the signal of telecommunication and the setting of liquid level controlled adjuster into compares, when probe value is lower than the liquid level of setting control, the liquid level controlled adjuster sends signal, opens solenoid valve, and water adds to the water bath through magnetic valve from running water pipe; When water level reached the high-value of setting control, probe value was higher than the liquid level of setting control, and the liquid level controlled adjuster sends signal, closes magnetic valve, stops moisturizing, to realize permanent water level; Simultaneously, the height of its water level can be set arbitrarily within its control range in advance by the liquid level controlled adjuster.Anhydrous in water bath, water level is low excessively or be in closed condition owing to tap water cut-off, magnetic valve damage, and causes the water bath middle water level to cross when low, the liquid level controlled adjuster will send signal and report to the police to liquid level alarm; Perhaps be in open mode owing to magnetic valve damages, running water can not stop, and moisturizing is when too much reaching the peak level that the liquid level controlled adjuster sets, and the liquid level controlled adjuster also will send signal and reports to the police to liquid level alarm; Thereby realize that thermostat water bath is unburnedly done, the function of permanent water level, anhydrous, the automatic alarm and protection of superelevation low water level.
Temperature control is consistent with conventional digital display thermostat water bath, namely can between 0～100 ℃, set arbitrarily by radiator valve, the temperature that the hygrosensor of water-bath detects becomes the signal of telecommunication, compare with the radiator valve setting value, when temperature less than when setting value, the radiator valve switch closure, electric heating tube is opened heating, when temperature arrived setting value, radiator valve disconnected electric heating tube and stops heating to realize thermostatic control.
The size of the utility model water-bath can design according to user's needs, but the laboratory must be equipped with running water or elevated tank (pond) to join with magnetic valve.This device is won gold research institute of Mining Group limited company laboratory and is applied in Guangxi, carrying out needing the someone to guard no longer as before when experiment is heated in water-bath, and can realize continual heated at constant temperature experiment in 24 hours, having changed this type of experiment can only do by day, and the disadvantage that the time can not be oversize; Simultaneously, cause because artificial recharge is untimely when having prevented the water-bath lack of water that equipment burns out, the failure of an experiment and security incident occurs, also reduced the experimenter, reduced experimental cost.
