Abstract
A temperature sensing device with the function of liquid level sensing comprises a sealing casing, a temperature sensing part and a liquid level sensing part, wherein the sealing casing consists of a junction box and a sheath pipe; the sheath pipe and the junction box are fixed and in sealed connection; a terminal block and a line outlet are arranged in the junction box; the temperature sensing part is a temperature detecting thermal resistance element, and is fixed at the inner bottom of the sheath pipe and is connected with the terminal block through a conducting wire; the liquid level sensing part comprises a reed pipe, a buoy, a magnet ring and a limiting stopper; the reed pipe is arranged at the inner middle part of the sheath pipe; the buoy, the magnet ring and the limiting stopper are all located outside the sheath pipe; and the sheath pipe is sleeved with the buoy capable of freely moving up and down. The temperature sensing device has the advantages that a temperature detection sensor and a liquid level detection sensor are placed in the same sheath pipe; all that is needed is to connect the terminal of the junction box with a controller through a conducting wire during wiring, thereby saving installation space and facilitating equipment production and actual operation; and the temperature sensing device is suitable for the temperature and the liquid level control for various electric heating hot water containers.
Description
(1) technical field
The utility model relates to the hot water tank temperature and the liquid level control technology of Electric heating, particularly a kind of temperature sensing device with the level sensing function.
(2) background technology
In the hot water control container of Electric heating, well heater will be placed on the bottom of container, and the water surface will be higher than well heater, otherwise well heater can be burnt out under the state of lack of water, and entire equipment is damaged.So in control, the temperature transmitter of measuring temperature will be arranged, the water level switch of measuring water level also will be arranged.That is to say that in the control of the water heater of this electrical heating type when water level reaches more than the level switch, electric heater begins heating, measures temperature by temperature transmitter, will stop the temperature heating when temperature reaches the temperature of setting.In equipment in the past, two transmitters, a water level transmitter, a temperature transmitter must be installed.Not only increase the position of opening of making, also increased workman's work, all brought a lot of troubles for maintenance to equipment.
(3) utility model content
The purpose of this utility model is at above-mentioned existing problems, and the temperature sensing device of a kind of simple in structure, safe and reliable, convenient maintenance, band level sensing function that applicability is strong is provided.
The technical solution of the utility model:
A kind of temperature sensing device with the level sensing function, comprise seal casinghousing, temperature sensing part and level sensing part, seal casinghousing is made of terminal box and protecting pipe, the protecting pipe lower end closed, the protecting pipe upper end open is also fixed with terminal box and is tightly connected, the terminal box internal fixation has connection terminal, and terminal box is provided with line outlet; Temperature sensing is partly surveyed resistance thermometer clement for temperature, and temperature detection resistance thermometer clement is fixed in the protecting pipe inner bottom part and is connected with connection terminal by lead; Level sensing partly comprises tongue tube, float, magnet ring and stop, tongue tube is arranged at middle part in the protecting pipe, be provided with the magnetic switch contact in the tongue tube and be connected with connection terminal by lead, float, magnet ring and stop all are positioned at the protecting pipe outside, stop is circular orifice and fixes with protecting pipe, and stop and tongue tube are in same horizontal position, float is the right cylinder that is provided with center pit, magnet ring is fixed in the center pit of float, the float that is fixed with magnet ring is enclosed within on the protecting pipe and but easy on and off moves, and the external diameter of stop is greater than the diameter of float center pit.
Working mechanism of the present utility model: stop is fixed on the protecting pipe outside according to the liquid level needs, and float just can fluctuate on protecting pipe.Float just is parked in spacing place when lack of water, when promptly having the float arrival tongue tube position of magnet, and output lack of water signal, tongue tube is in the effect lower contact closure in magnetic field, when float left this position come-up, opened the contact of tongue tube, thereby realize the detection to liquid level.The detection of temperature surveys resistance thermometer clement by temperature and circuit is realized.From connection terminal lead is got final product by the pulpit that line outlet is drawn out to outside the container during use, but will guarantee the sealing of line outlet and the heat-resisting and insulation of lead.
Advantage of the present utility model: temperature detection sensing and level detection sensing are placed in the protecting pipe, traditional temperature sensor and liquid level sensor are effectively combined, when wiring, only the terminal of terminal box need be linked to each other with lead with controller and get final product, saved installing space, make things convenient for equipment making and practical operation, be applicable to the temperature and the liquid level control of the hot water tank of various Electric heating.
