Abstract
The present invention provides a non-negative pressure hot water supply system for domestic use. The system comprises a steady flow compensator, a vacuum supressor, a water pump, a control cabinet, a heat user, a self-balancing regulating valve and a solenoid valve. A water supply pipeline of a municipal heat supply network is orderly connected with the steady flow compensator, the water pump and a heat user pipe network. Return water is delivered to the return water pipeline of the municipal heat supply network after passing through the self-balancing regulating valve and the solenoid valve. The present invention adopts non-negative pressure inlet water control and self-balancing regulating return water control, and the water supply pipeline and the return water pipeline of the municipal heat supply network are directly connected in series without adopting a heat exchanger. The heat consumption of the heat exchanger is saved. The present invention also has the advantages of land occupation and investment saving, water saving, energy saving and safe and reliable running.
Description
1, technical field
The present invention relates to a kind of domestic hot-water's pressurizing feedwater system, especially a kind of and municipal heat supply network directly is connected in series the non-negative pressure hot water supply system for domestic use of pressurization.
2, background technology
Domestic hot-water's centralizedly supply water supply system of the skyscraper of prior art adopts domestic hot-water's heat exchange station of independent partitions mostly, and need be provided with heat exchanger, water circulating pump etc., floor space is big, the equipment investment height, and it is lower at the heating agent supply water temperature, as when being lower than 80 ℃, it is low to adopt heat exchanger to carry out the thermal efficiency of secondary indirect heat exchange; Also having domestic hot-water's centralizedly supply water supply system of minority skyscraper to adopt water pump directly to be concatenated on the municipal heat supply network water supply line pressurizes, like this, water pump will influence other hot users of municipal heat supply network when big flow is worked, and in indoor pipe network system, often do not establish hot water backwater's pipeline, have energy dissipation, also there is minority domestic hot-water centralizedly supply system to be provided with water return pipeline, but after the water pump pressurization, only adopt simple decompression control, just directly be connected with municipal heat supply network water return pipeline, certainly will cause the unstability of pressure of return water and circling water flow rate, influence the backwater effect of system greatly.
3, summary of the invention
In view of above-mentioned the deficiencies in the prior art, the invention provides a kind of non-negative pressure hot water supply system for domestic use that takes up an area of little, reduced investment, saves water and energy.
The technical solution adopted for the present invention to solve the technical problems is: non-negative pressure hot water supply system for domestic use is by steady flow compensator, vacuum suppresser, water pump, switch board, hot user, self-balancing control valve and magnetic valve are formed, municipal administration heat supply network water supply line is successively through steady flow compensator, be connected with hot user's pipe network behind the water pump, its backwater is through the self-balancing control valve, be connected with municipal heat supply network water return pipeline again behind the magnetic valve, vacuum suppresser is installed on the steady flow compensator, and on the municipal heat supply network water supply line that is connected with the steady flow compensator import, be equiped with the intake pressure sensor, be provided with pressure of supply water sensor and supply water temperature transmitter at exit of pump, peak at hot user's pipe network is established exhaust apparatus, on municipal heat supply network water return pipeline, be provided with expansion tank and return water temperature transmitter, and between self-balancing control valve and magnetic valve, be provided with pressure of return water sensor, vacuum suppresser, water pump, the self-balancing control valve, magnetic valve, the intake pressure sensor, the pressure of supply water sensor, the supply water temperature transmitter, return water temperature transmitter and pressure of return water sensor are wired to switch board respectively.
Vacuum suppresser and steady flow compensator synergy to the pressure influence of municipal heat supply network water supply line, guarantee that the intake pressure sensor is more than the lowest service pressure of municipal heat supply network water supply line when avoiding water pump operation.
The self-balancing control valve is used to regulate the flow and the pressure of hot user's return pipe net, makes the coordination that balances each other of the flow of hot user's return pipe net and pressure and municipal heat supply network water return pipeline, eliminates the negative effect to other hot users.Magnetic valve then is to pass through its automatic opening and closing of the predefined programme-control of switch board according to the variations in temperature of return water temperature transmitter, has guaranteed the hot water temperature of hot user's pipe network.
The invention has the beneficial effects as follows, adopt no negative pressure water inlet control and self-balancing to regulate backwater control, realize being connected in series with municipal heat supply network water supply line and the direct of water return pipeline, heat exchanger and thermal losses thereof have been saved, not only saved and taken up an area of and investment, and saved water and energy, safe and reliable to operation.
