Abstract
The utility model relates to a constant-temp. water heater, a hot water pipe outlet of the water heater is provided with a thermo valve whose other inlet is connected with a cold water pipe. The interior of the thermo valve is provided with a slide valve, which is used for controlling the cold water quantity, the interior of the thermo valve is provided with a spring and a temperature sensor as driving power to push the slide valve. The interior of the thermo valve is provided with a group of screw mechanisms as the initial position of the presetting temperature sensor (leaving water temperature setting). The utility model has the advantage that in a normal state, the utility model is capable of ensuring water leaving out from the water heater with a constant temperature reliably no matter how the water pressure of a pipe network changes. The utility model reduces the adjusting times in use to improve the using quality.
Description
The utility model relates to a kind of constant-temperature hot water device.
At present, commercially available water heater is two big classes, and a class is a gas heater, and another kind of is the positive displacement electrothermal heater.The gas heater leaving water temperature is regulated, and adopts adjusting gas valve flame and cold water inflow size to realize.And this method is a kind of rough adjusting, and in fact people finally reach the use water temperature that is fit to oneself by regulating mixing valve (three-dimensional leading) at every turn when using water heater.And this control method is extremely unsettled, in case hydraulic pressure generation minor variations in the pipe network, as the increase and decrease of pipe network bypass delivery port, the increase and decrease of flow, will influence the variation of pipe network water pressure, cause the change of ratio of variation, the mixing valve mixing water of water heater inflow, influent pressure, original like this balance is promptly broken, and water temperature also changes.To regulate once more again, this not only bothers, and has a strong impact on service property (quality).Also there is similar phenomenon in the electrothermal heater.Owing to be subjected to the restriction of electrical power and volume, often the design temperature of water tank is much higher than serviceability temperature during use, even the upper limit, as the heat energy deposit.Control the use water temperature by mixing valve during use.But along with the outflow of water tank hot water, cold water promptly replenishes to water tank, and the water tank water temperature descends gradually, and original use water temperature of setting up promptly changes.In addition, the variation of pipe network water pressure also will influence the variation of mixing valve cold water input.Above-mentioned various situations all can increase mixing valve and regulate number of times, and influence service property (quality).
The purpose of this utility model is: a kind of given temperature value that needs only in the temperature province that is suitable for is provided, not influenced by the pipe network variation in water pressure, all can automatically control the constant-temperature hot water device with the leaving water temperature that equates to fixed temperature.
The purpose of this utility model is achieved in that the hot water mouth of pipe at water heater is provided with a thermostatic valve (2), and a guiding valve (3) is housed in thermostatic valve, forms valve with chuck (4), and its effect is the flow (hot water is unimpeded) of control cold water water inlet.A spring (1) is housed on the left side of guiding valve and is contained in heat detector (6) in the heat detector cover (5), its effect is the move left and right that promotes guiding valve.Be filled with the material of the high several special preparations of thermal coefficient of expansion in the heat detector of sealing, little axle (7) is extrapolated when the heat detector expanded by heating, and its reaction force is moved to the left guiding valve, to increase the cold water flow.The right at thermostatic valve is provided with the adjustable diameter and screw adjusting mechanism that is made up of screw rod (9), inner screw sheath (8), connecting rod (10) and handle (11), and its effect is an initial position of regulating heat detector, is marked with the temperature indication at handle appearance circumference, has more quantification during use.It is that high temperature chamber, B are that low temperature cavity, C are hybrid chamber that thermostatic valve is separated into three warm chamber: A by valve body (2), guiding valve, chuck.The runner of its water is to distribute like this: hot water hole, footpath (a) flows to hybrid chamber; Cold water is by flowing to hybrid chamber around guiding valve and the chuck slit; Mixing water flows out thermostatic valve by hole (b), (c).
Major advantage of the present utility model has:
1. in a single day the water heater temperature is set, and not influenced all by the pipe network variation in water pressure and can automatically control the constant-temperature effluent that equates with design temperature.
2. there is clear and definite water temperature to set mark, easy to adjust.
3. user terminal needn't dispose mixing valve, and unnecessary conduit fittings.As long as open tap, promptly guarantee constant-temperature effluent, save and regulate and sometimes hot and sometimes cold interference, improve service property (quality) greatly, reduce installation cost.
4. heat detector is that main several special materials are formulated by the high thermo-sensitive material of thermal coefficient of expansion, and it is good to have dilatancy, and heat sensitivity is strong, and control response is fast automatically, can control constant-temperature effluent immediately.
5. thermostatic valve adopts mechanical means, have simple in structure, good reliability, cost is low, and combustion gas, water inlet device architecture, the performance of gas heater are simplified.
Below in conjunction with accompanying drawing is example with the gas heater, and working condition of the present utility model is described further.
Fig. 1 is the structural plan of utility model constant-temperature hot water device
Fig. 2 is the structural plan of the thermostatic valve of utility model constant-temperature hot water device
Fig. 3 is the structural plan of the heat detector of utility model constant-temperature hot water device
Install and connection constant-temperature hot water device inlet and outlet piping and gas pipeline, set up suitable gas valve turn-knob, establish, set up a temperature value (making heat detector be determined to corresponding position) that is suitable for by thermostatic valve handle mark.Open water heater and make its work, cold water is through heating after the superheated water pipeline flow to thermostatic valve, when the water temperature of hybrid chamber is higher than set temperature value, the heat detector expanded by heating, little axially extrapolated, reaction force is moved to the left heat detector and heat detector cover, the promotion guiding valve is moved to the left, the slit of guiding valve and chuck increases, and cool water quantity increases, and then the hybrid chamber water temperature descends; When the water temperature of hybrid chamber is lower than set temperature value, the heat detector contraction of catching a cold, little axle release power is removed, spring moves right guiding valve, and guiding valve and chuck slit reduce, and the cold water input reduces, then the hybrid chamber water temperature rises, and makes the water temperature of hybrid chamber remain temperature constant state.Especially when design temperature is higher than high temperature chamber water temperature, then guiding valve and chuck driving fit, the gap disappears, and the cold water water inlet is closed.
This constant-temperature hot water device adopts machinery temperature control of relying on oneself, and simple in structure, easy for installation, response speed is fast, and cost is low.The thermostatic valve of this constant-temperature hot water device can be used as again and gas heater has been installed is adapted as the constant-temperature hot water device simultaneously, thereby has vast market prospect.
