The specific embodiment
Embodiment 1
Accompanying drawing 1 is the structural representation of one embodiment of the invention; As seen from the figure, initiative hot-water circulation heating system provided by the invention comprises:
One hot-water boiler 1;
One is positioned at the water tank 4 of hot-water boiler 1 top; Be provided with a vertical dividing plate 6 in the described water tank 4, this vertical dividing plate 6 is divided into hot hydroecium 5 and cold water chamber 12 with water tank 4; Be provided with the water-level control apparatus that is connected with hot hydroecium 5 and controls water level in it in the described cold water chamber 12, cold water chamber 12 tops also are provided with the blast pipe 8 that communicates with atmosphere;
One heat exchanger 14; And
Be installed in the check valve assembly 19 on the connecting line between heat exchanger 14 and the hot-water boiler 1; Described check valve assembly 19 comprises a threeway 17 and is attached thereto logical inlet one-way valve 16, outlet check valve 18 and balance pipe 13; Described balance pipe 13 other ends are connected with cold water chamber 12 lower ends; Inlet one-way valve 16 and 18 on outlet check valve allow current to flow to hot-water boiler 1 direction from heat exchanger 14, and be oppositely then obstructed.
Hot-water boiler 1 is connected by the lower end of outlet pipe 2 with water tank 4; One end of described heat exchanger 14 is connected by the lower end of heat supply water pipe 3 with water tank 4; The other end is connected with hot-water boiler 1 by return pipe 15, check valve assembly 19 and water inlet pipe 20 successively.
The water-level control apparatus of present embodiment can be U type water seal arrangement 7, the upper end of the down-comer 10 of this U type water seal arrangement 7 is passed vertical dividing plate 6 and is communicated with hot hydroecium 5 tops, and the upper end of the tedge 11 of U type water seal arrangement 7 communicates with open-topped water seal arrangement water storage case 9 bottoms.Water storage case 9 volumes of described U type water seal arrangement 7 equal the total measurement (volume) of its tedge 11 and down-comer 10, and water seal arrangement water storage case 9 lateral cross section areas are long-pending greater than the lateral cross section of tedge 11 and down-comer 10.Water storage case 9 volumes of U type water seal arrangement equal the tedge 11 of U type water seal arrangement and the total measurement (volume) of down-comer 10, in the time of can guaranteeing the pressure rising in hot hydroecium 5 like this, water in the down-comer 10 of U type water seal arrangement drains into water storage case 9 and retains, when the pressure in hot hydroecium 5 reduces, the water storage case 9 of U type water seal arrangement has the water that enough retains to return in the U type water sealing (sealing water) pipe, forms water seal again.Water storage case 9 horizontal sectional areas are much larger than the sectional area of water sealing (sealing water) pipe, and in the time of can guaranteeing that like this down-comer 10 interior water drain into water storage case 9, the water levels in the water storage case 9 increase less, and can fully obtain the cooling of cold water chamber 12, avoid excessive evaporation, and water storage reduces.Native system is interrupted the pressure and the water level of exhaust by setting hot hydroecium 5, thereby can determine the flow of each hot water forced circulation.The length of U type water seal arrangement 7 is long more, and then tedge 11 can be big more with the water-head of down-comer 10, and the pressure during hot hydroecium 5 exhausts is big more, and the flow of each hot water forced circulation is big more.
Its course of work is as follows:
At the initial stage of hot-water boiler 1 igniting, heating, along with the raising of water temperature, water-soluble on-condensible gas is separated out gradually in the circulatory system, successively drains into atmosphere by boiler discharging tube 2, hot hydroecium 5, U type water seal arrangement 7, cold water chamber 12 and blast pipe 8.Water temperature in the boiler 1 is further brought up near after the boiling temperature, produces a large amount of steam and enters U type water seal arrangement 7.Because the cooling of water at low temperature in the cold water chamber 12, steam is agglomerated in the U type water seal arrangement 7, has formed the water seal of U type gradually.
If heating demand is less demanding, the steam that boiler 1 produces is less, and steam all condenses after entering hot hydroecium 5, and then Ci Shi hot water cyclesystem is equivalent to natural circulation mode.
After heating demand improves, produce a large amount of steam water interfaces in the hot-water boiler 1 and enter hot hydroecium 5 through boiler discharging tube 2.Because the effect of threeway check valve assembly 19 middle outlet check valves 18, hot hydroecium's 5 internal pressures increase, water level in the water seal arrangement down-comer 10 of U type water seal arrangement 7 is descended, the water level of water seal arrangement tedge 11 rises, and the pressure that forms in hot hydroecium 5 is equal to the pressure reduction of the water-head of tedge 11 and down-comer 10.Under this pressure effect, the hot water in the hot hydroecium 5 is through heat supply water pipe 3 inflow heat exchangers 14, and the cooling back raises the water level of cold water chamber 12 earlier after the inlet one-way valve 16 of return pipe 15, threeway check valve assembly 19 and balance pipe 13 enter the cold water chamber 12 of water tank 4.Under poised state, the difference of the water level in cold water chamber 12 and the hot hydroecium 5 finally equals the water-head of tedge 11 and down-comer 10.Further rising along with hot hydroecium's 5 internal pressures, tedge 11 strengthens with the water-head of down-comer 10, when water level is lower than the extreme lower position of water seal arrangement 7 in the down-comer 10, the water column that gas in the hot hydroecium 5 passes in the tedge 11 enters cold water chamber 12, part condensation of gas is in cold water chamber 12, and the portion gas that do not condense is discharged cold water chamber 12 by blast pipe 8.Because the water columns in the tedge 11 are sneaked into a large amount of gases, density reduces significantly, thereby the gases that quickened in the hot hydroecium 5 enter cold water chamber 12, and the pressure in the hot hydroecium 5 are descended rapidly.After pressure in the hot hydroecium 5 descends, water-head in cold water chamber 12 and the hot hydroecium 5 makes the cold water in the cold water chamber 12 enter hot-water boiler 1 through balance pipe 13, outlet check valve 18 and boiler water inlet pipe 20, makes the steam water interface temperature reduction of hot-water boiler outlet pipe 2.In addition, after the pressure in the hot hydroecium 5 descended, the water in the water seal arrangement water storage case 9 flowed back to once more and is full of water seal arrangement down-comer 10, forms the water seal of U type again.Afterwards, along with the heating of hot-water boiler 1, the steam that boiler discharging tube 2 produces increases, and the pressure in the hot hydroecium 5 is raise, beginning pressure hot water circuit again.
Described water-level control apparatus can be connected to form by magnetic valve intermittent starting valve or mechanical intermittent starting valve and level sensor, as shown in Figure 4, when the water level of left side hot hydroecium 5 reaches the A point, level sensor 21 control magnetic valve intermittent starting valves (or mechanical intermittent starting valve) (21) are opened, hot hydroecium 5 and cold water chamber 12 are communicated with, gas pressure will reduce in the hot hydroecium 5, until identical with cold water chamber 12, reaches atmospheric pressure.When hot hydroecium's 5 rising of groundwater level during to the B point, magnetic valve intermittent starting valve cuts out, and hot hydroecium 5 and cold water chamber 12 are separate, gas pressure increases gradually in the hot hydroecium 5, and water level progressively descends, when reaching the A point, magnetic valve intermittent starting valve cuts out and opens, and repeats above process.
In order to reduce the noise of steam when boiler discharging tube 2 enters hot hydroecium 5, also can muffler be installed in outlet pipe 2 upper ends.Can also in threeway check valve assembly 19, establish the filter screen that is easy to clear up, stop up, destroy the circulation of threeway check valve assembly 19 to prevent foreign material.
