Description
Technical field
The present invention relates to establish a thermal source, be a kind of direct connection heating system for high-rise building of skyscraper and low-rise building heating simultaneously.
Background technology
Simultaneously for skyscraper and low-rise building heating method are, for skyscraper is established a boiler or established heat exchanger and low sound zone system is isolated.The former initial cost is big, operating cost is high, and the latter must have steam or the just economical rationality of high-temperature water thermal source.Jing Ji method is the most, utilizes the low-temperature hydrothermal origin system direct connection heating in original low district, for example directly connecting heat supply system without water tank for high-rise building that occurred in recent years and pressure-reducing valve class methods etc.
Because pressure-reducing valve in the market is not special in direct connection heating system designs, some performance parameters and not exclusively suitable heating system.Therefore directly bring to be used in and reduce pressure on the heating system that not only turn-off function is undesirable, but also the disappearance degassing function.Shortcomings such as they also all have complex structure, making trouble, spring fatigue in addition, circulating face rubber weares and teares and cost an arm and a leg, particularly system's operation also will be provided with electronic class valve shutoff when stopping, not only frequent movement is easy to damage, and also has the insecure critical defect of shutoff that has a power failure suddenly.Though yet directly connecting heat supply system without water tank for high-rise building has overcome the shortcoming of above-mentioned pressure-reducing valve aspects such as " shutoff, decompression, exhausts " effectively, it belongs to open system after all, can not be used to be provided with the heating system of deoxygenation owing to communicating with atmosphere.
Summary of the invention
The present invention is just at the shortcoming of above-mentioned prior art and a kind of direct connection heating system for high-rise building that proposes, this system has used block device to replace pressure-reducing valve and electronic class valve, it has not only overcome the shortcoming of above-mentioned pressure-reducing valve class and directly connecting heat supply system without water tank for high-rise building, but also has simple structure, waterpower control, reliability height, advantage such as easy to adjust and flexible for installation, cheap.
The object of the present invention is achieved like this: force (forcing) pump and control system thereof are with outdoor low district hot water line's water supply pressurization, after the process check-valves is delivered to high district's heat release, backwater then reduces pressure by block device and cuts off, networks with low district, wherein the front end from system's check-valves draws the high drive pipe, links on the block device that is located at high district return pipe.
When system moves, force (forcing) pump will supply water (heating agent) deliver to high drive water pipe He Gao district's radiator heat release successively, high service enters in the block device that is located at high district return pipe by the high drive water pipe, and block device is backed down, system forms loop, operate as normal; When the force (forcing) pump termination of pumping, the high drive siphon pressure reduces, and is not enough to back down block device, and block device cuts out, high sound zone system and low sound zone system are separated, thus the partition of assurance high low area system static pressure.
The present invention compared with prior art, it has utilized the pressure differential control block device of system's check-valves front end, realizes switch automatically, it is simple in structure, and the reliability of system is improved greatly.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is a system of the present invention connection layout.
Fig. 2 is the structural representation of block device.
The specific embodiment
Referring to Fig. 1, direct connection heating system for high-rise building has force (forcing) pump 1 and control system thereof, check-valves 3 He Gao district radiators 6, on height district return piping 7 block device 4 is set.Force (forcing) pump and control system thereof are used for the heating heating agent is sent into high district radiator.The 8th, low district radiator.
Referring to Fig. 2, block device is a jar shape, on jar water inlet pipe 9 and delivery port 16 are arranged, the bottom of water inlet pipe is provided with pressure-reduction outlet 21, and the upper end of connecting rod 23 is valve piston 22 fixedly, the lower end of connecting rod is big piston 17 fixedly, valve piston is the flap of pressure-reduction outlet in the water inlet tube chamber, big piston is arranged in the big piston chamber 15, bottom, big piston chamber is communicated with high drive water pipe 2, and the other end of this water pipe is communicated with system check-valves 3 front tube.For valve piston is closed more reliably, water hole 14 is set on the big piston chamber, be communicated with the jar chamber.When system moves, force (forcing) pump will supply water (heating agent) deliver to high drive water pipe He Gao district's radiator heat release successively, water supply enters the big piston chamber by the high drive water pipe, and the pressure that big piston bore is greater than valve piston, and supplying water, it is up to promote big piston, connecting rod and valve piston, pressure-reduction outlet is opened, at this moment, high district radiator backwater enters block device, successively by pressure-reduction outlet, jar chamber and delivery port, the pressure of Jiang Gao district backwater lowers, and flows in the low district return piping; When the force (forcing) pump termination of pumping, the high drive siphon pressure reduces, and the pressure differential that makes the big piston two sides is zero, valve piston is descending under the effect of height district backwater, pressure-reduction outlet is closed, high sound zone system and low sound zone system are separated with check-valves 3, thus the partition of assurance high low area system static pressure.
With outside the intrasystem gas discharge system, on block device tank body top exhaust outlet 10 is set in time, this exhaust outlet is connected with air bleeding valve 5.Enter the jar chamber of block device when backwater after, flow velocity reduces, and the gas in the backwater is separated, and gas rises and discharges through exhaust outlet to air bleeding valve 5.
Since the height district area of every building with highly be not quite similar, the pressure size that subtracts is also inequality, be provided with hand-operated pressure regulation appliance: pressure regulating cavity 18 is set below pressure-reduction outlet for this reason, the chamber wall in this chamber is two-layer, and two-layer chamber wall all is with water hole 19,13, and wherein the inner layer cavity wall is fixed, outer chamber wall 12 is rotary, the top of outer chamber wall is fixed on the gear wheel 11, large and small gears engaged, and pinion 24 driving shafts 25 are arranged on the outside of block device.High district backwater flows into a jar chamber through the water hole of pressure regulating cavity chamber wall again behind pressure-reduction outlet, the corresponding area in wall water hole, two-layer chamber is big more, and the water yield of outflow is many more, otherwise the water yield that flows out is few more.When needing to regulate, the manual drives axle, pinion, gear wheel rotate successively, drive outer chamber wall, regulate circling water flow rate and pressure.
To sum up the present invention utilizes the pressure differential of check-valves front end to realize the Push And Release of Parallel to the flow direction, cooperates block device, integrates the current limliting step-down, gentle water separation function is turn-offed in termination of pumping, and reliability improves greatly.
