TEMPERATURE REGULATING VALVE AND HEATING CONTROL APPARATUS USING THE SAME
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a temperature regulating valve (which will also be referred to as "heating valve") for regulating supply of heating water and to a heating control apparatus (which will also be referred to as "heating control system") for properly supplying the heating water to respective rooms by a precise control of the heating valve .
Description of the Related Art
Fig. 1 shows a diagram illustrating an entire construction of a conventional heating control system. As shown in Fig. 1, the conventional heating control system includes a heating apparatus 10 for heating water, a distribution pipe 12 for distributing water heated by the heating apparatus 10, heating valves 100, temperature regulators 20 provided at respective rooms Rl, R2, R3 and R4 for regulating a temperature in each room, and valve drivers 30 driven by the temperature regulators 20 and for controlling opening/closing of the heating valves 100.
With the conventional heating control system, when a temperature difference is generated between a desired temperature set by the user and the temperature of the rooms detected by a thermistor, the valve driver 30 is operated to open or close the heating valve 100 by an amount proportional to the temperature difference, so that the temperature of the rooms can be automatically controlled to be the desired temperature.
Construction and operation of the conventional heating control system 30 and the heating valve 100 will now be described with reference to the drawings. Fig. 2a is an exploded perspective view illustrating a combined relationship of the valve driver and the heating valve depicted in Fig. 1, and Fig. 2b is a sectional side elevation of the conventional heating valve in Fig. 1.
Referring to Fig. 2a, the valve driver 30 includes upper and lower cases 32 and 33 rotatably mounted with a reduction gear 36 consisting of a plurality of gears engaging with each other inside the cases. As shown in Fig. 2b, the reduction gear 36 has an output shaft 37 screwed to an engaging part 34 at a lower side of the lower case 33 such that the output shaft 37 can move up and down. The engaging part 34 is provided with a joining nut 35 for joining the heating valve 100 and the valve driver 30, such
that the joining nut 35 is fixed to the end of the engaging part 34.
The upper case 32 is mounted with a motor 31 for generating a power to revolve the reduction gear 36 at an upper side thereof, and the motor 31 has a rotational shaft 31a connected to a gear 31b engaging with the reduction gear 36. Thus, as the motor 31 rotates, the reduction gear 36 revolves to allow the output shaft 37 of the reduction gear 36 to move up and down. Additionally, the motor 31 is mounted with a cover 41 at the upper portion thereof for the motor not to be exposed to the outside. The upper case 32 is provided with a rotation detection sensor 39 inside thereof for detecting a rotational state of the reduction gear 36 to assume an opened or closed amount of the heating valve 100, and with a sensing plate 38 on the top surface of one of the gears constituting the reduction gear 36 for operating together with the rotation detection sensor 39 as a pair.
Further, the upper case 32 is mounted with a display plate 40 at the top surface thereof, which engages with the rotational shaft of one of the gears constituting the reduction gear 36 to rotate according to the revolution of the reduction gear 36 and displays the opened or closed amount of the heating valve 100 such that the user can recognize the opened or closed amount thereof.
Referring to Fig. 2b, the heating valve 100 is formed with a heating water inlet 111 at one side of a T-shaped body 110, to which the water heated at a boiler flows in, and with a heating water outlet 112 at the other side thereof for supplying the heating water, having passing through the body 110, to the rooms. Further, the body 110 is provided with a valve sheet 113 inside thereof for dividing the heating water inlet 111 and the heating water outlet 112, and the valve sheet 113 is formed with an opening 114 for communicating the heating water inlet 111 with the heating water outlet 112.
Meanwhile, the T-shaped body 110 is connected, at the upper side thereof, to a flux regulation operating part 120 mounted with a valve body 122 for opening or closing the opening 114 to control the flow of the heating water. The flux regulation operating part 120 is provided with a valve load 121 moving up and down, which is connected to the valve body 122 at one end of the valve load 121.
Further, the flux regulation operating part 120 is mounted with an elastic spring 123 inside the flux regulation operating part 120 for pushing the valve load 121 upward, and with a thread engagement part 124 on the outer peripheral surface of the flux regulation operating part 120 for engaging with a driving apparatus, which drives the heating valve 100. The valve load 121 is mounted to the flux
regulation operating part 120 such that it is protruded upward therefrom.
When a force is not applied to the valve load 121 of the heating valve 100 having the configuration as described above, the elastic spring 124 pushes the valve load 121 upward and. the valve body 122 also has an upward movement interlocked to the upward movement of the valve load, so that the opening 114 is opened to allow the heating water to be supplied to the rooms, raising the room temperature. However, when the rooms Rl, R2, R3 and R4 are heated using the conventional heating control system, there is a problem in that the heating water is not properly distributed to the respective rooms. For instance, different floor spaces of the rooms cause different lengths of the distribution pipe. The different lengths of the distribution pipe have an influence on the supply of the heating water, thereby causing a lack of propriety in supply of the heating water depending on the floor spaces of the respective rooms . Thus, the heating water generally flows to the rooms in which the supply of the heating water is smooth, so that some rooms often are not heated or, if heated, are slowly heated.
SUMMARY OF THE INVENTION
The present invention has been made to solve the above problems, and it is an object of the present invention to provide a heating valve, which can more accurately control supply of heating water. It is another object of the present invention to provide a heating control system, which can properly supply the heating water to respective rooms by more accurately controlling the heating valve.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily understand and repeat the present invention.
Fig. 3 is a structural block diagram of a heating control system according to the present invention.
As shown in the drawings, the heating control system according to the present invention includes a temperature regulator 20, a valve driver 30 and a heating valve 100, in which like elements will be denoted by like reference numerals of Fig. 2a in the drawings.
The temperature regulator 20 comprises a temperature set-up portion 21, a temperature detection portion 22 for detecting temperatures in respective rooms, a maximum flux set-up portion 23, a controller 24, and a motor driver 25.
The temperature set-up portion 21 may comprise a simple circuit including a variable resistance connected to
a typical dial-type adjusting lever, and may be achieved by a key-button type .
The temperature detection portion 22 may comprise a simple circuit including a thermistor. The maximum flux set-up portion 23 is provided to set up a maximum flux of the heating water per hour flowing out from the heating water outlet, and may be achieved by a key button.
In a preferred embodiment of the present invention, the maximum flux is determined depending on the ratio of total flux capable of passing through distribution pipe in respective rooms to the sum of the total flux in total distribution pipe. That is, if the total flux capable of passing through the distribution pipe of Rooms Rl, R2, R3 and R4 are 10 . , 6 1 , 5 1 and 4 t , respectively, the sum of the total flux in total distribution pipe is 25 . Here, the maximum fluxes per hour in Rooms Rl, R2, R3 and R4 are 10/25, 6/25, 5/25 and 4/25, respectively.
The reason for setting up the maximum flux in the present invention is that the heating water can be supplied to respective rooms in an amount within the maximum flux by allowing the heating valve to be opened or closed corresponding to the temperature difference between the room temperature and a desired temperature set by the user under the condition for controlling the opening and closing of the
heating valve such that the total flux does not exceed the maximum flux set by the user. It is very difficult to construct the distribution pipe such that the heating water can properly flow in respective rooms. Thus, in the present invention, the heating water can be properly supplied to respective rooms by intentionally adjusting a supplying load of the heating water flowing in the heating valves mounted at the distribution pipe of the respective rooms.
The controller 24 is preferably achieved by a microprocessor integrated with ROM or RAM, a differential circuit, an integral circuit, a comparing circuit, and the like. Preferably, as information of the maximum flux set by the user is input to the controller 24 through the maximum flux set-up portion, the controller stores the information. The controller 24 perceives the temperature difference after the set temperature and the detected temperature are input thereto from the temperature set-up portion 21 and the temperature detector 22, respectively, and monitors the information of the flux flowing in the heating valve 100 using a perception signal input from a hole sensor 124 of the heating valve 100. Depending on a control signal of the controller 24, the motor driver 25 adjusts the amount of the opening and closing of the heating valve to rotate the motor 31 of the valve driver 30 either in the clockwise direction or in the counter-clockwise direction.
According to a preferred aspect of the present invention, when the temperature difference occurs, the controller 24 opens the heating valve by the temperature difference under the condition of controlling the heating valve such that the heating valve is not further opened when the flux per hour flowing in the heating valve is the same as the maximum flux per hour stored beforehand.
In addition to the motor 31, the valve driver 30 includes a reduction gear 36, a rotation detection sensor 39, and an output shaft 37 of the reduction gear. Since the construction and operation of the valve driver 30 is the same as those of the conventional valve driver as described above, a detailed description will be omitted.
The heating valve 100 comprises a flux regulation operating part 120 provided with a valve load 121 and a valve body 122, a heating water inlet 111, a heating water outlet 112, an opening 114 communicating the heating water inlet 111 and the heating water outlet 112, a flux detection sensor 130 between the opening 114 and the heating water outlet 112 for detecting the flux of the heating water flowing out of the outlet.
The construction of the heating valve according to the present invention will now be described with reference to the drawings. Fig. 4 is a sectional side elevation of the heating valve according to the present invention, in which
like elements will be denoted by the like reference numerals of Fig. 2b in the drawings.
As shown in Fig. 4, the heating valve 100 of the present invention further comprises the flux detection sensor 130 at the inside of the heating water outlet 112 for detecting the flux of the heating water.
The flux detection sensor 130 comprises a propeller 131 rotated by the heating water flowing from the opening 114, a rotational shaft 132 connected to the propeller 131, a magnet 133 mounted at a predetermined portion of the rotational shaft 132, and a hole sensor 134 mounted at a position corresponding to the magnet 133. The flux detection sensor 130 further comprises a fixing screw 137 and a bearing 138 for connecting the propeller 131 and the rotational shaft 132 with an upper portion support 135 and a lower portion support 136, respectively.
Fig. 5 is a diagram illustrating an opening and closing operation of the heating valve of the present invention. As the temperature difference occurs, the controller
24 of the present invention lifts the valve body 122 by an amount corresponding to the temperature difference, allowing the heating water to flow to the heating water outlet 112. As the heating water flows to the heating water outlet 112 to rotate the propeller 131, the magnet 133 mounted at the
rotational shaft 132 also rotates. The rotation of the magnet 133 is detected by the hole sensor 134. The signal detected by the hole sensor 134 is input to the controller 24 of the temperature regulator 20, so that the controller 24 monitors the flux per hour.
Here, in Fig. 5, reference numeral "a" means the maximum opening and closing amount of the heating valve corresponding to the temperature difference, 'and reference numeral "b" means the maximum opening and closing amount corresponding to the value set by the maximum flux set-up portion of the temperature regulator.
That is, the heating control system according to the present invention opens the heating valve corresponding to the temperature difference under the condition of controlling the opening or closing of the heating valve such that the flux of the heating water does not exceed the maximum flux thereof, whereby the heating water can be properly supplied to the respective rooms by overcoming the difference in the propriety of the flow of the heating water in the rooms.
As apparent from the description, according to the present invention, the temperature regulating system forcibly controls the supply of the heating water flowing in the heating valves provided at the distribution pipe of the respective rooms, so that the heating water can be properly
supplied to the respective rooms to heat every room, thereby enhancing reliability of the product.
Additionally, the temperature of the rooms can be maintained without temperature difference between the rooms, thereby preventing unnecessary fuel consumption and saving energy produced from limited resources.
