Principle of work:
As shown in Figure 1, Divided-flow calorimeter is made up of windowpane 1, gland 2, O-ring seal 3, gear train and display unit 5, housing 7, impeller 9, stationary sleeve 10, turnbarrel 11, sector 12, sector bearing 13, snap ring 14, bearing pin 15, gear 16, screen pack 17, sleeve pipe 18, temperature difference sensing element 19, division board 21 and base plate 23.
Hot water enters in the housing 7 of component type calorimeter by hot water inlet 20 of registering one's residence, by sleeve pipe 18 epimere, heat is imported into temperature difference sensing element epimere 19a, and rise to the periphery of stationary sleeve 10 and turnbarrel 11, then enter impeller from centripetal runner b and eccentric runner a respectively, flow out from opening 6 and hot water outlet 8 of registering one's residence through impeller upper end and enter user.
Enter in the housing 7 of Divided-flow calorimeter from user's backwater out from backwater import 24, by sleeve pipe 18 hypomere, heat is imported into the thermometal straight-line helix of temperature difference sensing element hypomere 19c, and flow out from backwater outlet 22 and get back to heating system.
Fig. 2 shows the eccentric runner and centripetal runner that are formed by stationary sleeve 10 and turnbarrel 11.Stationary sleeve 10 is identical with the diameter of turnbarrel 11, wall thickness is identical, circumferentially all there is special-shaped gap 4, abnormity gap 4 two faces are not parallel, the extended surface in one of them face passes through the public axial line of two sleeves, the extended surface in another face is not by the public axial line of two sleeves, the special-shaped gap of two sleeves forms some centripetal runner b and eccentric runner a jointly, centripetal runner b is formed between face 10b by sleeve axial line, eccentric runner a is formed between face 10a not by quill heart line, blade due to impeller is radiate, if hot water has the effect that drive impeller rotates when eccentric runner a enters, if just do not possess the effect that drive impeller rotates when hot water enters along centripetal runner b.
As shown in Figure 3, temperature difference sensing element 19 is that the thermometal straight-line helix measure-alike by two sections, rotation direction is contrary is formed by connecting by connecting rod 19b, and the lower end of temperature difference sensing element 19 is fixed in sleeve pipe 18, and upper end can rotate freely, and is connected with gear 16.Because the rotation direction of two sections thermometal straight-line helix is contrary, sense of rotation when thus it expands with heat and contract with cold is also contrary; If when water temperature is identical up and down, its rotational deformation is cancelled out each other completely, would not produce relative rotation between the two ends of whole temperature difference sensing element; If when two ends exist the temperature difference, its two ends rotational deformation would not be offset completely, will produce an anglec of rotation corresponding to the temperature difference between the two ends of whole temperature difference sensing element.
The axial line of stationary sleeve 10 and turnbarrel 11 coincides, stationary sleeve 10 remains transfixion, turnbarrel 11 can be driven by temperature difference sensing element 19 and rotate to an angle, namely sector 12 is driven to swing by gear 16, driven rotary sleeve 11 rotates to an angle again, thus changes the sectional area of eccentric runner a and centripetal runner b, to change the proportionate relationship of eccentric flow and centripetal flow, and then changing the rotating speed of impeller 9, the temperature difference of hot water is converted to the rotating speed of impeller the most at last.
Illustrate, assuming that the mutual alignment of stationary sleeve 10 and turnbarrel 11 makes the sectional dimension of eccentric runner a and centripetal runner b maintain certain proportion in normal heat supplying process, as shown in Figure 2.Now, if registered one's residence, hot water temperature raises, return water temperature generally also can raise, but the amount that return water temperature raises is less, the temperature difference between the two will increase, the upper end of temperature difference sensing element 19 will rotate an angle in the counterclockwise direction, sector 12 is driven to rotate a corresponding angle along own axes clockwise direction by gear 16, thus driven rotary sleeve 11 is also rotated in a clockwise direction a corresponding angle, thus the cross section of eccentric runner a is increased, the cross section of centripetal runner b reduces simultaneously, when total flow is constant, the rotating speed of impeller 9 can be made to raise.
If registered one's residence, the water yield increases or reduces, although the sectional dimension of centripetal runner b and eccentric runner a does not change, but because pressure reduction increase or reduction can make centripetal flow and eccentric flow increase in proportion or to reduce simultaneously, the rotating speed of impeller 9 also can be made to improve or reduce.
The actual heat of user equals hot water flow and the product importing and exporting the hot water temperature difference.The present invention by register one's residence hot water flow with import and export the temperature difference and all transform rotating speed in order to impeller, the rotating speed of impeller just represents hot water flow and the product importing and exporting the hot water temperature difference, thus achieves the metering to the actual heat of user.
