Description
Technical field the utility model relates to a kind of heating loop to be improved, and particularly one makes the skyscraper high low area adopt same heating system, realizes the direct-connected device of enclosed.
Background technology is along with the urban construction fast development of China, and the skyscraper of various places is on the increase.In north of china in winter heating is the subject matter of high building project design and operational management.The urban heating network, various places is generally all determined by low-rise building (seven layers).If the mode of the static pressure by improving heating system solves skyscraper heating problem, need to improve the pressure of existing heating system, transform existing systems, change the low pressure radiator, this is unpractical.If adopt partition-type to connect, because the heat supply water temperature is low, heat exchange area is big, need take a lot of construction areas, increases investment.The more important thing is because heating parameter reduction after the heat exchange can make constructure heating unit are radiator quantity heighten, the pipeline overstriking, thus improve cost.And in recent years, indoor heating system has all adopted plastic pipe, and the heat supply water temperature drops to 80/55 ℃ by original 95/70 ℃, particularly adopts the cooling water of thermoelectric plant exhaust heat heating system, makes that this scheme that adopts heat exchanger more is difficult to realize.In the last few years, realized round skyscraper heating system and urban heating network that many solutions had appearred in mixed connection this problem that heats.Distinguish by municipal heating network heat supply such as low, high district establishes cutout by the force (forcing) pump pressurization above the top layer return pipe, and rotary stop apparatus is installed in the below, and the centre connects with return pipe, follows a tube connector simultaneously, makes the high low area of skyscraper realize directly being incorporated into the power networks.Second kind is by the decompression pressure regulating valve.Adopt compressed air to control the device that quick isolating valve, disconnects system.But all there is defective in they, i.e. cutout, and it is big that rotary stop apparatus takies space, the cost height, specification is more numerous and diverse, and floor space is big, and equipment component is many, and water hammer etc. takes place when water pump is out of service, brings many inconveniences for operation, maintenance.
It is convenient that utility model content the technical problems to be solved in the utility model provides a kind of fabrication and installation, take up an area of few, noise is little, entrapped air not in the pipeline recirculated water, avoid of the corrosion of airborne oxygen to heating equipment, thereby need not carry out gas-water separation, pipeline can turn round, and occurs the integrated skyscraper enclosed mixed connection heating installation of water hammer when stopping termination of pumping.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: this skyscraper enclosed mixed connection heating installation, on the chassis, be provided with water pump, piping and electric cabinet, be provided with water inlet pipe before the pump of water pump, link to each other with the feed pipe of municipal heating network, be provided with outlet pipe behind the pump, link to each other with the heating main-supply in the high district of skyscraper, it is characterized in that: hydraulic pressure back-water valve (BWV) setting height(from bottom) is lower than below district's heating system hydrostatic line, its water inlet pipe is connected with the main water return tube in high district, be provided with bypass pipe between check-valves on the outlet pipe behind its water inlet pipe and the pump is suitable for reading, be provided with check-valves on this bypass pipe in addition, also be provided with the hydraulic pressure control valve between hydraulic pressure back-water valve (BWV) and the water pump, the hydraulic pressure back-water valve (BWV) links to each other with the return pipe of municipal heating network by pipeline.Water pump can be installed on the chassis, can be 2 parallel connections.Can be provided with butterfly valve in the water return pipeline.
Behind starting mode of pump, because increasing a boiling water, hydraulic pressure pushes back water valve, make the circulation of heating water system; When water pump was out of service, the hydraulic pressure of hydraulic pressure control valve disappeared, and the hydraulic pressure back-water valve (BWV) cuts out automatically.Be the water hammer of avoiding water pump to have a power failure or causing to system when out of service, establish the bypass pipe of a band check-valves on the check-valves of main-supply before the hydraulic pressure back-water valve (BWV) with behind the pump, like this, current can only flow to feed pipe by return pipe.Behind starting mode of pump, hydraulic pressure increases, the closure of check ring on the bypass pipe, and water can not flow to return pipe, makes the high district of current direction heating system, and the hydraulic pressure control valve backs down back-water valve (BWV), high district water system normal circulation.When water pump was out of service, because effect of inertia can produce very big impulsive force, the hydraulic pressure back-water valve (BWV) cut out, and high district and low district are disconnected, and bypass line check valve is opened simultaneously, and heating water is in height district inner loop.Because there are not hysteresis in water pump and hydraulic pressure back-water valve (BWV) synchronization action, have eliminated the Hydrostatic Transfer Device problem after the termination of pumping.Owing to installed bypass line check valve additional at Gao Qu, the destruction of having avoided water attack that system is caused for preventing the generation of water hammer, requires to install the regulation of the bypass pipe that has check-valves between being responsible for for backwater.The utility model floor space is little, only needs after the addressing associated lines connected get final product commissioning test, and is safe and reliable, keep in repair easyly, and cost is low simultaneously, is convenient to popularize, for skyscraper employing city's net heat supply brings great convenience.
