Abstract
The utility model provides a positive displacement central water heater, comprising a body case, a heat exchanger, a burner, a water inlet, a water outlet, and at least one outflow pump, wherein the body case is composed of an upper part which is a water storage tank and a lower part which is an operating room. The heat exchanger and the outflow pump are fixed in the operating room. The burner is arranged on the lower part of the heat exchanger. At least one straight-way type gas flue arranged on the upper part of the heat exchanger is extended outside the body case through the water storage tank. The water inlet is communicated with the water outlet through the pipeline. Two electromagnetic valves are orderly arranged on the tube. The water inlet tube of the heat exchanger is communicated with the pipeline between the two electromagnetic valves, and the water outlet tube of the heat exchanger is communicated with the water storage tank. The water inlet of the outflow pump is communicated with the water storage tank through the pipeline, and the outlet of the outflow pump is communicated with the pipeline between the electromagnetic valve and the water outlet through the pipeline. The utility model has the advantages of low cost and easy installation and use and can be used to intensively supply hot water.
Description
Technical field
The utility model relates to a kind of gas heater, especially a kind of positive displacement central heater.
Background technology
At present, in the hotel, when school, factory, hairdressing place, beauty parlor etc. need centralizedly supply hot water, generally adopt boiler or large-scale water heater, equipment needs special place on the one hand, and infusion of financial resources is big; Equipment needs the special messenger to operate on the other hand, and needs periodic verification, maintenance, the operating cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of cost low, a kind of positive displacement central heater easy to install.
The purpose of this utility model is achieved in that a kind of positive displacement central heater, comprise that housing, heat exchanger, burner, water inlet, delivery port and at least one go out water pump, wherein: housing is divided into upper and lower two parts, and top is divided into storage tank, and the bottom is divided into the operating room; Heat exchanger, go out water pump and be fixedly mounted in the operating room; Burner is arranged on the heat exchanger bottom; Be provided with at least one through type flue outside storage tank extends to housing on heat exchanger top; Water inlet is communicated with by pipeline with delivery port, is provided with two magnetic valves on pipeline successively; The water inlet pipe of heat exchanger is communicated with pipeline between two magnetic valves, and the outlet pipe of heat exchanger is communicated with storage tank; The water inlet that goes out water pump is communicated with storage tank by pipeline, and the water outlet delivery side of pump is communicated with pipeline between magnetic valve and the delivery port by pipeline.
The further improvement of the utility model scheme is: can automatic water compensating valve be set at storage tank, keep water storage tank water level.
The utility model also can be realized like this: at storage tank temperature control probe is set, convenient water temperature of regulating the control storage tank automatically.
The utility model can also be realized like this: on the through type flue of hull outside air exhauster is set.
The utility model not only can realize the centralizedly supply of hot water, and not need the special place of installing and using owing to adopt said structure, thus invest little, operating cost is low; Simultaneously, the through type flue in the storage tank can utilize the water in the waste gas residual heat preheating storage tank, improves the thermal efficiency, further reduces operating cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 housing, 11 storage tanks, 12 operating rooms, 13 through type flues, 2 heat exchangers, 21 water inlet pipes, 22 outlet pipes, 3 burners, 4 water inlets, 5 delivery ports, 6 go out water pump, 7 pipelines, 8 magnetic valves, 9 magnetic valves, 10 automatic water compensating valves, 20 temperature control probes, 30 air exhausters.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe further, but do not constitute any restriction of the present utility model.
As shown in Figure 1, positive displacement central heater of the present utility model comprises that housing 1, heat exchanger 2, burner 3, water inlet 4, delivery port 5 and one go out water pump 6, and housing 1 is divided into upper and lower two parts, and top is divided into storage tank 11, and the bottom is divided into operating room 12; Heat exchanger 2, go out water pump 6 and be fixedly mounted in the operating room 12; Burner 3 is arranged on heat exchanger 2 bottoms; Be provided with a through type flue 13 outside storage tank 11 extends to housing 1 on heat exchanger 2 tops; On the through type flue 13 of housing 1 outside, be provided with air exhauster 30.Water inlet 4 is communicated with by pipeline 7 with delivery port 5, is provided with magnetic valve 8 and magnetic valve 9 on pipeline 7 successively; The water inlet pipe 21 of heat exchanger 2 is communicated with pipeline 7 between magnetic valve 8 and the magnetic valve 9, and the outlet pipe 22 of heat exchanger 2 is communicated with storage tank 11; The water inlet that goes out water pump 5 is communicated with storage tank 11 by pipeline, and the outlet that goes out water pump 5 is communicated with pipeline 7 between magnetic valve 9 and the delivery port 6 by pipeline.In storage tank 11, be provided with automatic water compensating valve 10.In storage tank 11, be provided with temperature control probe 20, be used for regulating the control water temperature.
When the utility model specifically uses, at first water inlet 4 automatic water compensating valves 10 are communicated with the tap water supply pipeline, with delivery port 5 and hot water user pipeline connection; Join dependency is controlled power supply and gas pipeline then, and the water temperature of storage tank 11 is set, and utilizes the switch of temperature control probe 20 signal controlling magnetic valves 8 and magnetic valve 9, realizes the circulation heating to supply water heating or storage tank 11 hot water; Reach the control of storage tank 11 water temperatures.Concrete operation principle is: open when magnetic valve 8, then magnetic valve 9 cuts out, and running water enters heat exchanger 2, and burner 3 igniting are to heat exchanger 2 heating, and hot water enters storage tank 11; Can be after going out water pump 6 and starting to user's hot-water supply.Do not reach design temperature as the temperature in the storage tank 11, then magnetic valve 9 is opened, magnetic valve 8 cuts out, going out water pump 6 starts, hot water in the storage tank 11 is squeezed in the heat exchanger 2 once more, burner 3 igniting by heating that the hot water in the storage tank 11 is circulated, reach design temperature to heat exchanger 2 heating.The utility model can be used as the concentrated hot-water supply device of hotel, beauty parlor, factory, school, sauna chamber etc.
