Shown in Fig. 1, work as heat supply in winter, and when the water supply path 1 and the temperature difference of the reclaimed water of backwater storehouse 13 are more than temperature difference threshold, by known
General knowledge is understood, during winter, the hot water temperature in water supply path 1 is higher, and in the backwater storehouse 13 after heating equipment 10
Coolant-temperature gage is relatively low, therefore the intumescent material swells degree slided between the heat conduction baffle 2 of cutting part 3 and first is more than the cunning
Intumescent material swells degree between the dynamic heat conduction baffle 4 of cutting part 3 and second, the slip cutting part 3 is driven to drive the section
Stream restriction 7 is moved, and increases the gap between the flow restriction portion 7 and baffle plate 12, then flow increases, in heating equipment 10
In hot water residence time reduce, reduced with extraneous heat-exchange time, return water temperature reduces amplitude and reduced, it is final realize supply, backwater
The temperature difference is constant.Work as heat supply in winter, and when the water supply path 1 and the temperature difference of the reclaimed water of backwater storehouse 13 are less than temperature difference threshold, the cunning
Intumescent material swells degree between the dynamic heat conduction baffle 2 of cutting part 3 and first be less than the slip heat conduction of cutting part 3 and second every
Intumescent material swells degree between plate 4, the slip cutting part 3 is driven to drive the flow restriction portion 7 to move, described in reduction
Gap between flow restriction portion 3 and baffle plate 12, flow reduce, the increase of hot water residence time in heating equipment 10, and outer
Boundary's heat-exchange time increase, return water temperature reduce amplitude increase, and final realization supplies, backwater temperature difference is constant.
As shown in Fig. 2 work as summer cooling, and the water supply path 1 and the temperature difference of the reclaimed water of backwater storehouse 13 are more than temperature difference threshold
When, from common knowledge, during summer, the cold water temperature in water supply path 1 is relatively low, and the backwater after heating equipment 10
Coolant-temperature gage in storehouse 13 is higher, therefore the intumescent material swells degree between the slip heat conduction baffle 2 of cutting part 3 and first is small
Intumescent material swells degree between the slip heat conduction baffle 4 of cutting part 3 and second, drive the slip band of cutting part 3
Move the flow restriction portion 7 to move, increase the gap between the flow restriction portion 7 and baffle plate 12, then flow increases, with heat
Cold water residence time in equipment 10 is reduced, and is reduced with extraneous heat-exchange time, and return water temperature elevation amplitude reduces, final to realize
It is constant for, backwater temperature difference.Work as summer cooling, and when the water supply path 1 and the temperature difference of the reclaimed water of backwater storehouse 13 are less than temperature difference threshold,
The intumescent material swells degree slided between the heat conduction baffle 2 of cutting part 3 and first is more than the slip cutting part 3 and second
Intumescent material swells degree between heat conduction baffle 4, drive the slip cutting part 3 to drive the flow restriction portion 7 to move, subtract
Gap between the small flow restriction portion 7 and baffle plate 12, then flow reduction, the cold water residence time in heating equipment 10 increase
Add, it is final to realize that confession, backwater temperature difference are constant with the increase of extraneous heat-exchange time, the increase of return water temperature elevation amplitude.
A kind of self-operated type constant-temperature difference control valve and its system provided by the utility model, have following
Beneficial effect：
1st, it ensure that the temperature difference of each end of main is constant, adjust user's water, reduce conveying energy consumption caused by energy supply；
2nd, using expanding material, using self-operated type regulation technology, it is ensured that the accuracy and peace of system constant difference automatic control
Full reliability；
3rd, only needing the direction for changing flow restriction portion to meet heat supply in winter and the operation of summer cooling simultaneously needs
Ask.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
