Description

The high-low storey building heating installation

One, technical field

The utility model belongs to the high rise building heating technical field, is a kind of facility that is used for high-low storey building direct heating.

Two, background technology

At present, in high rise building heating, high district and the most economical method of low district's heating are to utilize the low-temperature heat source system direct heating in original low district, its specific practice is the directly connecting heat supply system without water tank for high-rise building (see figure 1), it is in the top in height district system's backwater to be entered the step-down exhaust apparatus, and the form with non-flowing full turns back in the low district return pipe then.The deficiency of its existence is: 1, this system has wasted the potential energy that water pump lifting supplies water and increased because of falling with non-flowing full, simultaneously, because this system is an open architecture, causes air access to plant in the pipeline, increases oxygen uptake chance, corrosion pipeline and device.2, owing to the step-down exhaust apparatus complex structure that this system adopted, be prone to fault and have potential safety hazard.When it can't operate as normal, the high pressure backwater is the impact low-pressure pipe network directly, causes pipe network and device damage, causes unnecessary loss.

Three, summary of the invention

The purpose of this utility model, be the deficiency at above-mentioned directly connecting heat supply system without water tank for high-rise building, a kind of totally enclosed high-low storey building heating installation is provided, it not only can flow to low district by the full-section pipe-flow backwater, reduce energy dissipation, but also improved the stability of device.

For achieving the above object, the technical solution adopted in the utility model is: comprise force (forcing) pump, radiator, advance, water return pipeline, be characterized in having adopted plural force (forcing) pump, lead on the inlet pipeline of high district radiator being installed on low district after its parallel connection, after each pressurization delivery side of pump connects the water supply non-return valve, one the tunnel is connected with the automatic open and close valve high-voltage tube, after another road parallel connection, is connected with the inlet pipeline that leads to radiator through non-return valve.The full-section pipe-flow return pipe of radiator outlet is connected with upper end, middle part and the lower end outlet thereof of energy release respectively through flow control valve.Lead at the energy release on the water return pipeline in low district the automatic open and close valve that links to each other with high-voltage tube is installed.

The utility model adopts technique scheme to have following advantage: 1, heating system is a full-closed structure, and air can access to plant, has prevented the corrosion of pipeline and device.2, adopt the full-section pipe-flow form, the lift when having reduced water pump operation has reduced energy consumption and operating cost.3, the energy release is simple in structure, is difficult for stopping up.Simultaneously, because automatic open and close valve is by high-voltage tube, open and close to pressure-controlled by force (forcing) pump.So just improved the stability of device, safe and reliable to operation.4, the automatic open and close valve high-voltage tube picks out from two non-return valves centres that the pressurization delivery side of pump is connected on the pipeline, because the blocking effect of non-return valve, two force (forcing) pumps need not cut off the automatic open and close valve high-voltage tube when exchanging automatically, and are simple to operation.

Four, description of drawings

Fig. 1 does not have water tank direct connection heating system schematic diagram for the background technology middle-high building.1 is force (forcing) pump among the figure, and 13 is radiator, and 16 are the step-down exhaust apparatus, and 17 is non-flowing full return pipe.

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the structural representation of the energy release among Fig. 2.

Five, the specific embodiment

As shown in Figure 2, two force (forcing) pumps 1 (one of them is a stand-by pump) of employing of the present utility model are installed in parallel in low district on the inlet pipeline 3 of high district radiator 13, and high district is delivered in the low pressure water supply in low district.The outlet of each force (forcing) pump 1 is behind water supply non-return valve 2, and one the tunnel is connected with automatic open and close valve high-voltage tube 6 through control valve 5, is connected with inlet pipeline 3 after another road parallel connection, and leads to radiator 13 heat radiations through non-return valve 18; The full-section pipe-flow return pipe 15 of radiator 13 outlets divides three the tunnel through flow control valve 12, inserts front end, middle part and the lower end outlet thereof of energy release 11.Lead at energy release 11 on the water return pipeline in low district the automatic open and close valve 7 that links to each other with high-voltage tube 6 is installed.It is opened and closed to pressure-controlled by force (forcing) pump 1 by high-voltage tube 6, promptly only just can open when force (forcing) pump 1 starts, and is in closed condition at ordinary times.Import and export end at automatic open and close valve 7 is separately installed with backwater control valve 9 and pressure-reducing valve 10.Like this, backwater is just under the control of flow control valve 12, enter flowing full return pipe 15 with full-section pipe-flow, enter in the energy release 11 of upwards spraying water through flow control valve 12 again and release energy, after automatic open and close valve 7 enter in the low district pipe network, thereby realized that high district energy does not return to low district, has also realized the purpose of conserve energy.The effect of pressure-reducing valve 10 is assisted decompression, does not work in case the energy release breaks down, and it can cushion the backwater high pressure, avoids low district pipe network is caused damage significantly.The outside at automatic open and close valve 7 and pressure-reducing valve 10 is parallel with bypass valve 4.Its effect is need overhaul the said equipment the time, and it is opened UNICOM's pipeline.End at the force pipe 6 that leads to automatic open and close valve 7 also is provided with check valve 8, and available rod tool is carried out the flexibility inspection by it to the parts in the automatic open and close valve 7.As shown in Figure 3,11 employings of energy release are gone up to truncated cone-shaped, are down that reverse frustoconic, centre are the housing 19 of cylindrical formation, are provided with the upwards sparge pipe 14 that the lower end passes from housing 19 middle parts in the housing 19.The last end entrance of energy release 11, lower end outlet reach the lower end of the sparge pipe 14 that passes from the housing middle part, communicate with full-section pipe-flow return pipe 15 through flow control valve 12 respectively.When backwater by full-section pipe-flow return pipe 15 through flow control valve 12 from the upper end of energy release and the sparge pipe 14 at middle part when entering, current are through upwards ejection of sparge pipe 14, collide with the backwater that enters from its upper end and to release energy, be mixed into low district with the backwater that enters from the outlet of energy release 11 lower ends then, thereby realized the backwater decompression of high district.Low district heating system is identical with heating form in the background technology.

The utility model is simple in structure, and is reasonable in design, is easy to Installation and Debugging, and easy access is a kind of safe, Heating System of High Residential Buildings efficiently.
