Description

A METHOD AND A DEVICE FOR DRIVING A REMOTE TEMPERATURE
$ ADJUSTING VALVE
BACKGROUND OF THE INVENTION
Field of the Invention
δ The present invention relates to a method and a device for driving a remote temperature adjusting valve for a water heating system. More particularly, this invention relates to more efficient water heating effected by enabling a temperature sensing part to sense the indoor temperature and remotely operate an automatic temperature adjusting valve 10 in a condition where it is separated from a pipe through which hot water passes.
Description of the Prior Art
Referring to the driving gear of a conventional hot water adjusting valve, a bellows 101 which contains liquid or gas is installed in the
15 inside of a temperature setting head 100 to be installed in the indoor atmosphere and a push stick 103 is connected between the bellows 101 and a valve disk 102, so the contained liquid of gas expands or contract according to a variation of ambient temperature of a bellows tube by coming into indirect, contact with the ambient temperature of the bellows, i 20 and the valve disk 102 connected thereto variably adjusts the open area of a hot water inflow mouth the valve body by going up and down, so that the volume of water which passes through the tube per unit hour is adjusted and proper heating temperature is thereby maintained, as illustrated in Figure 1.
However, the conventional hot water adjusting valve which uses a bellows being used by installing it on one side of a hot water pipe, a certain amount of heat is continually transmitted to the bellows from the hot water pipe. Consequently, the temperature of the bellows becomes higher than ambient temperature and the function of adjusting heating temperature by opening and closing the valve disk according to a variation of temperature is not fulfilled delicately and correctly.
Therefore, in the case where rooms are heated, as in Korea, by installing water tubes under the floor and circulating heated water(60"C to 70°C) therethrough, the heating temperature of each room is unequal. In a multistory building, heating temperature varies in each story.
To solve such a problem, hot water tubes were specially laid in each story of a multistory apartment, but it incurred a large amount of expense.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to sense a variation of the indoor temperature delicately and correctly by installing a temperature sensing part which senses the indoor temperature and operates a valve separately from the valve with which a hot water tube is connected.
Another object of the present invention is to provide a method and a device for driving a remote temperature adjusting valve for a water heating system which uses thermal energy efficiently beacuse a valve disk is enabled to be fast in response velocity and precise in opening and closing operation displacement by transmitting the form transformation stress of a form memory alloy spring installed within the temperature sensing part to the adjusting valve by means of oil pressure.
Such a method and a device for driving a remote temperature adjusting valve for a water heating system as described hereinabove is characterized in that the temperature sensing part which moves a fluid by the for transformation stress of the form memory alloy spring and adjusting valve provided with disk valve which compresses a counteracting spring by oil pressure resultant from the movement of the fluid and conducts opening and closing operations are connected by a tube.
Now, a preferred embodiment of the present invention will be described in detail according to the drawings attached hereto.
Description of the Drawings
Figure 1 is a cross-sectional view illustrating a conventional automatic temperature adjusting valve.
Figure 2 is a cross-sectional view illustrating an automatic temperature adjusting valve according to the present invention.
Detailed Description of the Invention
As illustrated in Figure 2, a tube 50 through which a fluid 51 passes is installed in the upside of a combined body 80 with a disk valve 70 which is installed over a hot water tube 90 where an inflow tube part 91 and an outflow tube part 92 communicate with each other and which operates elastically by means of an counteracting spring 81 installed therewithin and, in the inside of the combined body 80, an adjusting valve 60 united with a cylinder 61 wherein a piston 62 which operates upward and downward by the movement of the fluid 51 is installed, a cylinder 31 into which the fluid 51 and a piston 32 are inserted in the center of a body part 30 and a setting head 20 having a plurality of vent holes 22 on the circumference and a guide bar 21 in the inner center are united with said body part 30, but a temperature sensing part 10 in which an axial housing of the piston 32 with a form memory alloy spring 40 installed is inserted is connected with said guide bar 21 by said adjusting valve 60 and tube 50. forking effects of the present invention constituted in such a manner will be described as follows :
The form memory alloy spring 40 is a compressed coil spring. The austenite modification beginning temperature which begins to return to originally memorized form is 10°C and the austenite modification finishing temperature which completely returns to originally memorized form is 25°C. The form memory alloy spring 40 which possesses such a characteristic senses the indoor temperature through the vent holes 22 by being installed within the temperature sensing part 10.
When the indoor temperature stands at higher than 25βC, the form memory alloy spring 40 is completely transformed into austenite form from artensite form. At the same time, it returns to its originally memorized form and pushes the pistion 32 by generating stress and moves the fluid 51 within the cylinder 31 to the cylinder 61 of the adjustung valve 60 through the tube 50. Then the piston 62 the adjusting valve 60 comes down. As it compresses the upper surface of the push stick 70, a support 71 compresses the counteracting spring 81 and a disk valve 72 thereunder intercepts an inflow of hot water by blocking a hot water inflow mouth.
Assuming that the force of the form memory alloy spring 40 above 25°C is Fl and the force of the counteracting spring 81 which tries to return to the originally manufactured form of compression spring by the elasticity of wire rod when it is compressed is F2, an expression of Flj>F2 is formularized and such operations"as stated above are thereby conducted. When the indoor temperature is below 10°C, the expression becomes F2>F1 according as the form memory alloy spring 40 is transformed into martensite from austenite and, with the counteracting spring 81 elongated as it was, the fluid 51 moves into the cylinder 51 of the temperature sensing part, the push stick 70 rises, the disk valve 72 is separated from the hot water inflow mouth and hot water flows.
At this time, the form memory alloy spring 40 is in the state of being compressed in the form of martensite.
According to the present invention as heretofore described, the temperature adjusting valve can be opened and closed by conducting operations delicately to a variation of room temperature, so that proper level of room temperature can be continually maintained. Moreover, thermal energy can be efficiently used by precise opening and closing operation displacement.
