Description
Technical field
The utility model relates to a kind of gas, liquid mixing arrangement, particularly a kind of intelligent water supply temperature regulating device of the temperature that the gas or the liquid of two kinds of different temperatures can be mixed into any setting automatically.
Background technology
In similar inventions, a kind of is to adopt corrugated tube to utilize its characteristic of expanding with heat and contract with cold, and changes the resistance of ducting of cold water pathway and hot water passageway by connecting rod and spool, thereby changes hot water or cold water's flowrate proportioning, reaches the purpose that constant temperature supplies water at present.In this class device, corrugated tube be temperature-sensing element be again the valve core driving force source owing to there is not the additional force source, driving force is slightly inadequate.In order to strengthen the action dynamics, the corrugated tube domestic demand is filled with low boiling point working medium.Also has a kind of electric control valve, with the motor is the power switch valve, but its performance is comparatively simple, only open and close for valve, can not be at any time according to the action of actual temperature, therefore with the temperature difference size by-pass valve control that temperature is set, the fluctuation of temperature is bigger, valve also because switch is frequent, is easy to produce fault, belongs to the primary products of electric control valve.The more novel motorized valve of some that go out in recent years, can realize the Based Intelligent Control of temperature, but because employing is that hot cold water directly mixes, so when the temperature difference is big, can produce explosive sound because of the rapid expansion of liquid, the temperature difference is big more, explosive sound is big more, so all can not control high-temperature steam.Present water supply temperature regulating device has following deficiency in application: temperature-controlled precision is subjected to the temperature and pressure variable effect of two kinds of water of access to plant bigger, therefore often needs to set up preposition steady gentle stable-pressure device; The variation of delivery rate also can influence the temperature stabilization of mixed water, and when big flow and low discharge, temperature has than large deviation; Hot water cold water directly carries out the mixing of water through reducing pipe, because the temperature difference of hot and cold water is bigger, causes the expansion rapidly of volume and produces noise of blasting, is commonly called as water hammer; Can not control high pressure-temperature gas.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of energy-conservation, water saving is provided, saves material, saves the intelligent water supply temperature regulating device that can regulate and control at a distance of manpower.
For achieving the above object, the technical solution adopted in the utility model is: comprise the heat exchanger that is connected with hot water or cold water's pipeline and be arranged on temperature probe in the heat exchanger, be characterized in, the cold water or the hot water pipeline that are connected with heat exchanger are provided with electric control valve, electric control valve is connected with the control output end and the valve opening signal feedback end of control instrument, and temperature probe is connected with the temperature signal incoming end of control instrument by lead.
Another characteristics of the present utility model are: control instrument comprises the testing circuit and the temperature setting circuit of comparator circuit and the parallel connection that is connected with the input end of comparator circuit, the input end of testing circuit is connected with temperature probe, the output terminal of comparator circuit also is connected with the valve opening feedback controller, and the output terminal of comparator circuit is connected with electric control valve by on-off circuit; What on-off circuit adopted is limit switch; Also be respectively arranged with hand valve on the pipeline at the two ends of electric control valve, and also be parallel with gate valve in the outside of two hand valves.
Because the utility model cold water or hot water pipeline are provided with the electric control valve that is connected with control instrument, temperature probe is connected with control instrument, thereby opening or closing of the comparison of the temperature that records by temperature probe and the temperature of setting decision electric control valve realized that temperature control is accurate, temperature adjustment makes things convenient for, can have been controlled high-temperature steam, remote operation, equipment is simple, easy to operate, flow passage components are less scaling, the pressure loss is little, the temperature, pressure that comes water is not had effects such as specific (special) requirements, mixed water temperature be constant.

Fig. 2 is the circuit block diagram of control instrument of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to Fig. 1, the utility model comprises the heat exchanger 4 that is connected with hot water or cold water's pipeline and is arranged on temperature probe 3 in the heat exchanger 4, the hot water pipeline that is connected with heat exchanger 4 is provided with electric control valve 2, on the pipeline at the two ends of electric control valve 2, also be respectively arranged with hand valve 10, and the outside at two hand valves 10 also is parallel with gate valve 11, electric control valve 2 is connected with the control output end and the valve opening signal feedback end of control instrument 1, and temperature probe 3 is connected with the temperature signal incoming end of control instrument 1 by lead.
Referring to Fig. 2, control instrument 1 of the present utility model comprises the testing circuit 5 and the temperature setting circuit 6 of the parallel connection that comparator circuit 7 is connected with input end with comparator circuit 7, the input end of testing circuit 5 is connected with temperature probe 3, the output terminal of comparator circuit 7 also is connected with valve opening size feedback signal potentiometer 8, the output terminal of comparator circuit 7 is connected with electric control valve 2 by on-off circuit 9, and what on-off circuit 9 adopted is limit switch.
Its principle of work is (establishing controlling plumbing fixtures is hot water pipeline): be installed in temperature probes 3 in the heat exchanger 4 and convert the actual temperatures in the heat exchanger 4 to electric signal and deliver to control instrument 1, compare with the temperature that the user sets by control instrument 1, form " overgauge ", " minus deviation " or " zero-deviation ", according to deviation of signal state and variation tendency, control instrument 1 decision is left big electric control valve 2 (motor just changes) and is still turned down electric control valve 2 (motor counter-rotating), still is failure to actuate.Because the change of temperature has certain hysteresis, can provide the valve opening degree signal to control instrument 1 at any time this moment by valve opening size feedback signal potentiometer 8, control instrument 1 can relatively determine to continue to open, cut out, still stop the action of electric control valve 2 according to the size of the size of the temperature difference and open degree, when the temperature difference of design temperature and actual temperature is big, can reach the purpose of rapid cooling like this, thereby make ducted actual temperature consistent, reach the purpose that makes water temperature or steam keep steady temperature with the temperature that the user sets.In actual use, can set the permission fluctuation range of predetermined temperature, can reduce the number of starts of motor like this, prolong the life-span of motor.
Directly mix so that produce huge water hammer noise because of adopting hot cold water in order to change some same device, and the defective that therefore can not carry out high-temperature gas control, this device has adopted heat exchanger, hot cold water mixes in the heat exchanger the inside, eliminated water hammer fully, for especially suitable with the occasion of high-temperature steam heat supply.
