Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
Fig. 1 show the utility model embodiment be used for heating system in to the device 10 of two grades of moisturizings of net 30 supply
Schematic flow sheet in hot systems.The device 10 eliminates the impact that two grades of moisturizings of net 30 are brought to city tap-water pipe network, and section
Running water is saved as the operating cost of moisturizing.
As shown in figure 1, the device 10 includes header tank 1, first switch valve 2 and second switch valve 3.Header tank 1 have into
Mouth and outlet, its import are connected by first switch valve 2 with one-level net 20, and outlet passes through second switch valve 3 and two grades of phases of net 30
Even so that the water of the storage one-level of header tank 1 net 20, the moisturizing demand of two grades of nets 30 is met.The import of first switch valve 2 and one-level
Net 20 is connected, and outlet is connected with the import of header tank 1 so that first switch valve 2 allows one-level net 20 when opening to 1 case that catchments
Interior water filling.The import of second switch valve 3 is connected with the outlet of header tank 1, and outlet is connected with two grades of nets 30 so that second switch valve
3 allow header tank 1 when opening to two grades of moisturizings of net 30.
Device 10 of the present utility model connects the one-level net 20 and two grades of nets 30 of heating system, header tank 1 by header tank 1
The water in one-level net 20 can be stored, prevents from disappearing when losing moisturizing or operation in two grades of warm season water-filling, failures first of net 30
Water shortage when consuming moisturizing.The import of header tank 1 is connected with the outlet of first switch valve 2, the import of first switch valve 2 and one-level
Net 20 is connected so that first switch valve 2 allows the water filling into header tank 1 of one-level net 20 when opening；The outlet of header tank 1 and the
The import of two switch valves 3 is connected, and the outlet of second switch valve 3 is connected with two grades of nets 30 so that second switch valve 3 is permitted when opening
Perhaps header tank 1 is to two grades of moisturizings of net 30.The device 10 is in two grades of 30 water-fillings of net, and elimination brings punching to city tap-water pipe network
Hit, also the cost of reduction water.Wherein, the present apparatus 10 forms fully closed using the backwater of heat exchange station one-level net 20 as two grades of moisturizings of net 30
Formula system, water quality will not form secondary pollution, it is ensured that the safe operation of heating system.With city tap-water (especially ladder water
Valency) compared with the cost of water treatment, steam power plant heat supply initial station or district boiler room large-scale water treatment system into
This is lower, and water standard is higher, reduces to pipe network (the especially easy fouling of resident's Household radiator, blocking radiator etc.)
Corrosivity, extends the service life of pipe network.
In this preferred embodiment, device 10 also includes control assembly (not shown).Control assembly is configured to
Open first switch valve 2 when liquid level in header tank 1 is less than the first default liquid level, and the liquid level in header tank 1 is higher than the
First switch valve 2 is closed during two default liquid levels, wherein the first default liquid level is less than the outlet of header tank 1, and second presets liquid level
Higher than the outlet of header tank 1.Control assembly ensures the water in header tank 1 by controlling first switch valve 2, meets two grades of nets
30 moisturizing demand, realizes full-automatic water-supplying, without special messenger's operation, substantially increases production efficiency and economic benefit, reduction is changed
Heat stations manpower operating cost.Control assembly can carry out the control of two position by mechanical or electronic type method,
Can also be by control valve, water pump etc., so as to realize semi-automation or full-automatic Liquid level.For example, control
Component is preferably controlled with float switch (being usually used in water closet), electronic type liquid-level switch or liquid level relay is controlled etc..
In this preferred embodiment, device 10 also includes the 3rd switch valve 4.The import of 3rd switch valve 4 and one-level net
20 are connected, and its outlet is connected with the import of first switch valve 2.3rd switch valve 4 is typically in open mode, meets control assembly
It is the automatic water filling of header tank 1 to control first switch valve 2.But, under specific circumstances, the 3rd switch valve 4 is above-mentioned available for closing
Automatic water filling.First switch valve 2, the switch valve 4 of second switch valve 3 and the 3rd in the device 10 can all be off valve.Cut
Only valve frictional force between sealing surface during opening and closing is small, relatively durable, easy to manufacture, easy to maintenance, low in being applicable not only to
Pressure, and suitable for high pressure.
In one-level net 20, steam power plant's heat supply initial station or district boiler room to cell heat exchange station are feed pipe, otherwise are backwater
Pipe；In two grades of nets 30, cell heat exchange station to user is feed pipe, otherwise is return pipe.In the present embodiment, the 3rd switch valve 4
Import be connected with the return pipe of one-level net 20 so that header tank 1 is injected by the water of heat-exchange unit, one-level net 20 is not influenceed
Normal work；The outlet of second switch valve 3 is connected with the feed pipe of two grades of nets 30.
In this preferred embodiment, there are the parts such as liquid level observing pipe, blowoff valve on header tank 1.In the depth side of header tank 1
Liquid level observing pipe is provided with upwards, facilitates the liquid level of artificial observation header tank 1, conventional liquid level observing pipe can be transparent connection
Device.Blowoff valve is provided with the sidewall bottom of header tank 1, scavenger precipitation protects the water of the reclaimed water of header tank 1 in impurity of bottom etc.
Matter.The header tank 1 can advantageously be softened water tank.
In this preferred embodiment, the moisturizing that device 10 can also be connected between header tank 1 and second switch valve 3
Pump, small pump draw water to two grades of moisturizings of net 30 in second switch valve 3 after opening from header tank 1.
In summary, the device 10 of the utility model embodiment can both eliminate warm season a large amount of concentration use such as water-filling first
To the greater impact of city tap-water pipe network formation during water, the cost of running water is saved again.Central heating enterprise from heating plant to
The special water pipe of each heat exchange station laying moisturizing can also be solved the above problems, and still, multiple heat exchange stations are formed with heating plant initial station
The special grid of moisturizing, it is adjusted, and investment is huge, and payoff period is longer, without exploitativeness.
Although the utility model is described by reference to preferred embodiment, model of the present utility model is not being departed from
In the case of enclosing, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as not depositing
