Abstract
The utility model discloses an automatic constant pressure heating system, relating to the heating systems; currently, due to the lack of the constant pressure heating system which is economical and safe and is suitable for large-scale residential central heating, a lot of energy sources are wasted; the utility model respectively arranges control valves on the two water pipes between a circulating pump and a water filling tank as well as arranges a pressure adjusting valve before the circulating pump to achieve automatic constant pressure. The system of the utility model has the advantages of high security, simple structure, low cost and easy operation, which saves energy and is suitable for residential central heating.
Description
Technical field
The utility model relates to a kind of heating system, especially relates to a kind of automatic constant-pressure heating system.
Background technology
At present, existing automatic constant-pressure heating system mainly contains two kinds: a kind of is to utilize water head tank to realize automatic constant-pressure, being about to water head tank unites to make as expansion tank and water supply tank and is used for realizing automatic constant-pressure, this kind automatic constant-pressure heating system is applicable to single household or the use of a few family, is not suitable for large tracts of land and uses; Another kind is to utilize nitrogen pot to reach the purpose of automatic constant-pressure, be about to nitrogen pot and unite use as expansion tank and water supply tank, but the cost of nitrogen pot is too big, considers to be not suitable for extensive popularization from economic angle.At this present situation, the applicant carries out a large amount of development works.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, small investment, energy-saving effect significantly and can improve the automatic constant-pressure heating system of heating quality and security.
Technical solution of the present utility model is:
A kind of automatic constant-pressure heating system, comprise resource of water supply, boiler, circulating pump, small pump, radiator, water supply tank, connecting line, it is characterized in that: the pressure regulator valve before also comprising two water pipes of connection circulating pump that control valve is installed respectively and water supply tank and being installed in circulating pump, boiler is a heat supply horizontal boiler, and water supply tank and circulating pump are in one plane.
The position of boiler, water pump and radiator can conversion in this automatic constant-pressure heating system.
Control valve in this automatic constant-pressure heating system is: magnetic valve, folded valve, pneumatic operated valve and common valve, preferred hydraulic operated valve.
This automatic constant-pressure heating system lift is 25 meters, is fit to the sub-district central heating of 6-7 layer, and heating area can reach 100000 meters
2
The course of work of this automatic constant-pressure heating system: after boiler 1 and whole system were all filled with water, the water level of water supply tank 6 must not be lower than 1/2 of total capacity.Height and the withstand voltage situation of boiler according to radiator 8 positions, start circulating pump 2,3, utilization is installed in pressure regulator valve 7 before the circulating pump and regulates the pressure of whole systems (preferably boiler is about 2.5MPa, can adjust as required, pressure of return water must not be lower than 1MPa), constantly observe the water supply tank water level and carry out moisturizing, behind the whole system constant pressure, could start boiler.Before starting boiler, must start circulating pump earlier, two control valves of opening installation this moment on the water pipe that links to each other.When the initial stage of boiler startup, water temperature raises gradually, the also corresponding thereupon expansion of the volume of water, and additional water and gas enter water supply tank along return pipe automatically through a phase connecting leg before the circulating pump, and water supply tank communicates with atmosphere, and gas is discharged.When system's dehydration or boiler cooling, the water of water supply tank enters boiler and whole system from the middle phase connecting leg of two pumps supply circulating pump automatically, recovers original water level automatically, keeps system pressure stable.When circulating pump was out of service, two control valves on two phase connecting legs were closed, and the water of water supply tank will overflow.
The beneficial effects of the utility model are:
1, simple in structure, small investment is saved the energy;
2, water supply tank and expansion tank are united two into one, simplify the structure, reduced cost;
3, adopt hydraulic operated valve and pressure regulator valve to unite use, increased security, improved heating quality;
4, be applicable to the sub-district central heating.
Description of drawings
Fig. 1 is the structural representation of the utility model automatic constant-pressure heating system
The name of each sequence number is called among the figure:
1-boiler, 2,3-circulating pump, 4,5-hydraulic operated valve, 6-water supply tank, 7-pressure regulator valve, 8-radiator, 9-small pump
The specific embodiment
Now the technical solution of the utility model is described further by the following example.
Be the automatic constant-pressure heating system among Fig. 1, comprise: resource of water supply, boiler, radiator, dynamical system: circulating pump, small pump; Voltage-regulating system: water supply tank, hydraulic operated valve, pressure regulator valve and connecting line.Present embodiment adopts hydraulic operated valve, and 25 meters of lifts are fit to 100000 meters of areas
2The sub-district central heating of 6-7 layer.
Its operation principle is: after boiler 1 and whole system were all filled with water, the water level of water supply tank 6 must not be lower than 1/2 of total capacity.Height and the withstand voltage situation of boiler according to radiator 8 positions, start circulating pump 2,3, utilization is installed in pressure regulator valve 7 before the circulating pump and regulates the pressure of whole systems (preferably boiler is about 2.5MPa, can adjust as required, pressure of return water must not be lower than 1MPa), constantly observe the water supply tank water level and carry out moisturizing, behind the whole system constant pressure, could start boiler.Before starting boiler, must start circulating pump earlier, two hydraulic operated valves 4,5 that are installed in this moment on the water pipe that links to each other can be opened under the effect of circulating pump automatically.When the initial stage of boiler startup, water temperature raises gradually, the also corresponding thereupon expansion of the volume of water, and additional water and gas enter water supply tank along return pipe automatically through a phase connecting leg before the circulating pump, and water supply tank communicates with atmosphere, and gas is discharged.When system's dehydration or boiler cooling, the water of water supply tank enters boiler and whole system from the middle phase connecting leg of two pumps supply circulating pump automatically, recovers original water level automatically, keeps system pressure stable.When circulating pump was out of service, the water that two hydraulic operated valves on two phase connecting legs will cut out water supply tank automatically will overflow.
