Abstract
An electronic constant-temperature water mixing valve comprises a valve seat, a fixed ceramic valve plate, a movable ceramic valve plate, a rotary block, a cover plate 1, a cover plate 2, a stepping motor, a temperature sensor, a valve bonnet, a rubber gasket and a controller. A cold water inlet, a hot water inlet and a mixed water outlet are arranged on a valve body in T-shaped arrangement and communicated with a water mixing cavity in the movable valve plate; and the valve body is connected with the controller by a connecting wire. When the electronic constant-temperature water mixing valve is used, outlet water temperature is set by the controller, and the electronic constant-temperature water mixing valve automatically adjusts the proportion of cold inlet water to hot inlet water in real time by controlling rotation of the stepping motor according to the set temperature and outlet water temperature change detected by the temperature sensor, thereby ensuring that outlet water temperature can be kept constant around the set temperature.
Description
Affiliated technical field
The utility model relates to a kind of electronic thermostatic water admixing device, is applicable to the occasion of similar domestic hot-water's purposes such as family, hotel, leisure shower center.
Background technique
Mixed water valve has used very extensive in people's life as a kind of device of regulating water temperature, brought facility for people's life.Mixed water valve commonly used at present mainly contains two kinds from regulative mode: a kind of is the common mixed water valve of band ceramic valve core, in use people are by rotation and the displacement of the moving valve plate in the handle drive ceramic valve core of regulating mixed water valve with respect to quiet valve block, control cold water inlet and hot water inlet's size reaches the ratio of regulating the hot water or cold water, thereby reaches the purpose of regulating water temperature.But this mode is regulated not directly perceived, the user can only regulate with sensation, it is overheated or cold excessively to cause easily, and when entering water temp in the using process change or during variation in water pressure water-exit temperature also and then change, at this time the user is with regard to constantly regulating handle is to obtain suitable temperature, and it is very inconvenient to use.Another mixed water valve is mechanical constant-temperature water mixing valve, this constant-temperature water mixing valve has partly overcome the shortcoming of common mixed water valve, it drives moving of spool by the expansion or the contraction of built-in bulb in different water temperatures, thereby reach the purpose that the ratio of regulating hot and cold water adjusts coolant-temperature gage, and be the setting temperature that is adjusted to the user automatically, avoided water temperature to be subjected to the influence of entering water temp and variation in water pressure, it is still not directly perceived that but this constant-temperature water mixing valve is regulated, the user will be adjusted to the temperature of scale correspondence by the scale on the valve body, the user sees is not actual water-exit temperature but the temperature of scale correspondence, the various errors that produce in user's vision deviation and the manufacture process make the water-exit temperature that obtains by such adjusting have very mistake, be difficult to reach the ideal temperature that the user wants, the while complex structure, spool and bulb all are copper materials, grown easy fouling service time, caused the spool clamping stagnation, its automatic regulatory function is affected even has lost.
Summary of the invention
Shortcoming at above-mentioned two kinds of mixed water valves, the utility model provides a kind of electronic thermostatic to mix water valve, this electronic thermostatic mixes water valve can show actual water outlet water temperature, can directly be adjusted to the water-exit temperature that needs and keep constant temperature automatically by controller, use intuitive and convenient, and as water admixing device, non flouling behaviour can use for a long time with ceramic plate.
The technological scheme that its technical problem that solves the utility model adopts is: this electronic thermostatic mixes water valve and is made up of valve body and controller two-part, there is connecting line to connect between valve body and the controller, button and display device are arranged on the controller, and valve body comprises again: valve seat, ceramic quiet valve block, ceramic moving valve plate, moving block, cover plate 1, cover plate 2, stepper motor, temperature transducer, valve gap and rubber washer.Have on the valve seat to be cold water inlet, hot water inlet and the mixed water water outlet that the T font is arranged, separate each other,, communicate with mixed water cavity in the ceramic moving valve plate by the aperture of valve seat bottom and the aperture on the ceramic quiet valve block; Pottery moving valve plate diameter is littler than ceramic quiet valve block, and the mixed water cavity of a dumbbell shape is arranged in the middle of the ceramic moving valve plate, and two grippers cooperations and fixing on two draw-in grooves and the moving block are arranged at ceramic moving valve plate top simultaneously, are fixed on the valve seat by cover plate 1 again; Stepper motor is fixed on the cover plate 1, and the stepper motor rotating shaft is entangled by moving block, and moving block can drive ceramic moving valve plate and rotate in several angle under the rotation of stepper motor rotating shaft; Mix on the water water outlet temperature transducer is installed, be fixed on the valve seat by cover plate 2.When this electronic thermostatic mixes water valve work, temperature transducer on the valve body can detect coolant-temperature gage in real time, and and controller on user's setting temperature make comparisons, if water-exit temperature height, then controller control driven by motor pottery moving valve plate rotates to the cold water inlet direction, make the cold water inflow increase and thereby the hot water inflow reduces to make water-exit temperature to reduce direction to temperature to regulate, motor stops operating when water-exit temperature equals setting temperature; Equally, if water-exit temperature low regulate in the other direction, equal setting temperature up to temperature, and as long as controller can be controlled motor and makes adjustment when the variation of entering water temp or hydraulic pressure causes water-exit temperature minor variations to occur at once, thereby reach the purpose of constant temperature.
The beneficial effects of the utility model are: can see actual water-exit temperature intuitively, and can obtain the temperature that the user wants by the button on the operation control, the mixed water valve of electronic thermostatic can carry out automatically according to the minor variations of water-exit temperature, and real-time adjustment makes water-exit temperature remain on setting temperature, not only intuitively but also convenient, the utilization of ceramic valve plate simultaneously can reduce noise, prevent incrustation scale, improve working life.In addition, the location of stepper motor can be accomplished rapidly and accurately, and the controller function simple, intuitive makes things convenient for child and old man to use.
