The heat source water-supply pipe joint and the heat supply network water-supply pipe joint are arranged at the same level, and the heat source water-return pipe joint and the heat supply network water-return pipe joint are arranged at the same level. An upper end socket and an air bleeder are respectively arranged on the top of the tank body, and a lower end socket and a blow-off valve are respectively arranged at the bottom of the tank body. The hydraulic decoupling tank decouples a heat source water system and a heat supply network system, and circular flow of the heat supply network is adjusted according to changes of heat load, so that an energy saving effect of a distributed variable-frequency water pump heating system is functioned fully and energy consumption in transmission and distribution of the heating system is reduced.
Description
Technical field
The present invention relates to heating system equipment, more particularly, to a kind of waterpower decoupling tank for central heating system.
Background technology
At present, most of modern city heats in the winter time and adopts central heating system, and water circulating pump concentrated setting is in warm
At source, water circulating pump is selected according to farthest, least favorable user, is used for overcoming thermal source, heat supply network and heat user SR.In heat supply
Near-end (at the thermal source) heat user of system, defines excessive available pressure head.In order to meet near-end heat user circular flow,
Must be provided with flow control valve, unnecessary available pressure head is consumed, this meaningless restriction loss is water circulating pump design side
Method causes in itself.
Water circulating pump function at thermal source was decomposed by the distributed variable frequency water pump system of domestic application in recent years,
It is respectively provided with water pump at thermal source and heat user.This heating system can eliminate the ineffective energy consumption of system so that the conveying of system
Energy consumption reduces.Particularly under partial load condition, adjust the circular flow of heat supply network, reduce the transmission ＆ distribution energy of heating system further
Consumption.However, in actual applications, the minimum discharge of the hot-water boiler at thermal source in central heating system cannot be below 70%, leads
Cause distributed variable frequency pump heating system can not give full play to its power savings advantages, the regulation of the circular flow of heat supply network simultaneously makes pot
In stove there is respective change so that the operation conditions of boiler is unstable in discharge.
Content of the invention
For technical problem present in prior art, the present invention provides a kind of central heating system waterpower that is used for decouple
Tank, by thermal source water system and hot net water system decoupling so that the circular flow of heat supply network is adjusted according to the change of thermic load
Section, thus fully playing the energy-conserving action of distributed variable frequency pump heating system, reduces the transmission ＆ distribution energy consumption of heating system.
In order to solve technical problem present in prior art, the present invention adopts the following technical scheme that
A kind of decouple tank for central heating system waterpower, including tank body, described side wall be distributed with heat up and down
Source water supply interface tube and thermal source backwater interface tube；Its opposite side wall be distributed with heat supply network water supply interface tube and heat supply network backwater up and down
Interface tube, described thermal source water supply interface tube is highly identical with described heat supply network water supply interface tube, described thermal source backwater interface tube and institute
State that heat supply network backwater interface tube is highly identical, the top of described tank body is respectively equipped with upper cover and vent valve, the bottom of described tank body
It is respectively equipped with low head and blowoff valve.The antetheca of described tank body is equidistantly distributed with 4 temperature monitoring windows along along its longitudinal centre line,
Described temperature monitoring window is located between described thermal source water supply interface tube and described thermal source water outlet interface tube.
The bottom of the back wall longitudinal centre line of described tank body is provided with manhole.
The invention has the beneficial effects as follows, first, the present invention realizes the waterpower decoupling of thermal source water system and heat supply network water system, makes
Thermal source water system is run according to metered flow, and in heat supply network water system, flow can be adjusted according to thermic load, thus fully
Play distributed variable frequency pump energy saving in heating system effect, reduce the transmission ＆ distribution energy consumption of heating system.Second, the present invention passes through
Waterpower decouples and designs multiple temperature monitoring windows on tank and grasp the Temperature Distribution of decoupling tank, mixed regimen condition at any time it is ensured that waterpower solution
The trouble free service of coupling tank.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention provides a kind of central heating system waterpower that is used for decouple tank, described tank body 1
Side wall be distributed with thermal source water supply interface tube 21 and thermal source backwater interface tube 22 up and down；The distribution up and down of its opposite side wall
It is provided with heat supply network water supply interface tube 31 and heat supply network backwater interface tube 32, described thermal source water supply interface tube 21 and described heat supply network feed pipe connect
Mouth 31 is highly identical, and described thermal source backwater interface tube 22 is highly identical with described heat supply network backwater interface tube 32.The top of described tank body 1
Portion is respectively equipped with vent valve 4 and upper cover 5, and the bottom of described tank body is respectively equipped with blowoff valve 6 and low head 7.Wherein, on described
End socket 5 and low head 7 are respectively fixedly connected with the top of tank body and bottom.In addition, it is contemplated that tank body 1 is operationally, heat supply system
