Description
Technical field
The present invention relates to a kind of installation method and special-purpose pre-buried hot water water pipe sub-assembly of household metering heating pipeline.
Background technology
For energy-conservation, in the central heating design of the commercial house, all should adopt household metering at present.But in fact household metering is difficult to promote, and the service life that it is calorimeter that household metering is difficult to promote a major reason technically is short, and the cleannes of water quality be cannot say for sure to demonstrate,prove in the heating system.Existing household metering heating pipeline all melting welding is an one, except that radiator detachably, other pipeline all can not be taken cleaning apart, and the whole system process of washing is difficult to guarantee the cleannes of pipeline, cause the particular pollutant in the pipeline to be difficult for discharging, after these particular pollutants are heated by the hot water in the heating system, the water quality in the long-time contaminated system of meeting, this is one of reason of calorimeter weak point in service life.
In the design of existing goods room household metering radiator heating, common design has three kinds, and they are respectively: 1. single tube tandem indoor system.2. radiate the double hose system.3. annular reversed return system.
Back one group of radiator water inlet of single tube tandem indoor system is from the backwater of last group of radiator, this will cause following problem: but the water emptying in one group of last radiator, water in other radiator all can't emptying, if in the pressure testing in winter, do not perform antifreezely, except that one group of last radiator, other radiator all can be freezing, the bigger dirt of density can't be discharged in the ground pipe laying, and promptly dirt such as the grains of sand and metal welding slag all can't be discharged.
Radiation double hose system need use the metal water knockout drum, all there is the control ball valve on each road of metal water knockout drum, these ball valves damage easily, as long as there is one road ball valve to damage on the water knockout drum, the necessary integral replacing of water knockout drum is because each group radiator all will be installed control valve, the ball valve of water knockout drum is sheerly unnecessary, in case the heating back is damaged, replacing is got up very difficult, so the metal water knockout drum is the big hidden danger of one in the household metering heating pipeline.Existing metal water knockout drum all is installed in indoor, it must above ground levelly be installed, this can't discharge the particular pollutant that enters in the pipeline when installing, also make the pressure testing water in the radiator can't emptying, cause the freezing radiator of pressure testing in winter, metal water knockout drum not only price is expensive, and the used pipeline of this design is many.Cost height not only, and extremely inconvenient when causing the owner to fit up ground.
Two-tube annular reversed return system: in the process of this system's operation, the dirt in the radiator can accumulate in the buried backwater main because of washing away, and the dirt ratio of discharging in the system pipeline is easier to this SR minimum.The weak point of this system is to use ground pipe laying less than one times than the single tube train more, and cost is slightly higher than single tube train, but this system has solved the problem that exists in preceding two kinds of system forms, is the system form of pipe laying heating compatibly.
The installation method of existing plastic water pipe pipeline all is melting welding at the scene, because the dust and sand of erecting bed is more, adds that the skill differential of installer's welding technology is bigger, and fusion welding quality is difficult to guarantee.All joint made by flame weldings place must be behind pressure test leak-detecting could be hidden.During melting welding heat time heating time long, can produce the melting welding shrink-ring in the weld pipe, serious shrink-ring even can blocking pipeline.The melting welding shrink-ring is not cleared up in on-the-spot melting welding, can't check the melting welding shrink-ring yet, and the melting welding shrink-ring can increase SR, also strengthens operation energy consumption; Also shelter evil people and countenance evil practices easily on the melting welding shrink-ring, influence the water quality of heating system.
The installation method of existing household metering heating pipeline all is usually: building in face of the ground, lay along the wall limit earlier and fixedly heating installation for the backwater main, build ground again.For the confession return branch and the pressure test leak-detecting of radiator are installed, when building ground, the ground that leads to radiator arm place wouldn't be built.Installing and fixing of radiator will be carried out after metope just whitewashes, fix radiator after, connect the confession return branch of radiator again, and then pressure testing, treat pressure testing pass through to manage check and accept after, could the teeming radiator for the ground at return branch place.Because repeatedly intersecting, heating pipeline installation and civil engineering carry out, project progress not only interacts, also influencing heating pipeline installs and the civil engineering quality, cause radiator by cement mortar and coating repeated pollution, add the phenomenon of trampling radiator is often arranged when window frame and glass are installed, cause the radiator that has fixed loosening, the heating pipeline that pressure testing is good leaks again, before the heating engineering final acceptance, water power contractor will drop into more artificial cleaning radiator, the also mopping again that has, the trimming pipeline.
After key is handed in the existing goods room, many owners will remove bright dress heating pipeline and radiator, reinstall hidden pipe, and select high-grade radiator handsome in appearance for use, also there are many owners will change the position of radiator, the design and installation method of the existing heating pipeline of this explanation, the requirement of Chinese's pursuing individualityization that incompatible affluence is fast got up, thus caused limited resources and artificial waste.
