Abstract
The present invention discloses a steam heat exchanger for heating, which comprises a steam jet pump, an electric valve and a water can and is characterized in that an inlet of the electric valve is used for filling steam, and an outlet of the electric valve is connected with an inlet of the steam jet pump; an outlet of the steam jet pump is connected to the top of the water can; the upper part of the water can is connected with a hot water outlet; the lower part of the water can is connected with a tap water inlet and is connected to the steam jet pump by a stop valve; two temperature sensors for respectively controlling the electric valve to turn on and off are arranged in the water can. Compared with the prior art, the present invention has the advantages of reasonable design, simple and fast operation and high automatically controlled coefficients, and improves operation stability and safety of the device.
Description
Technical field
The present invention relates to the steam heating device, especially for the steam heat exchanger of heating.
Background technology
In the prior art, steam heating generally adopts steam jet pump to add hot water with steam, substitutes heating circulation pump hot water is offered the user.Using method is that steam and running water enter steam jet pump by stop valve, by steam jet pump the domestic hot-water are directly offered the user again, as shown in Figure 1.This using method exists following some deficiency: (1) is because the user directly connects with steam jet pump, and the acute variation of user side flow causes the jet pump changes in flow rate violent, thereby it is bigger to make that supply water temperature fluctuates.(2) in service, in order to adapt to user's needs, need frequent steam regulation valve, the workload when having increased operation greatly.(3) steam jet pump needs frequent start-stop.
Summary of the invention
At deficiency of the prior art, the purpose of this invention is to provide a kind of steam heat exchanger that is mainly used in heating, it can be realized the automatic control of steam jet pump and regulate automatically, reduces workload and supply water temperature fluctuation when moving, improves the stability and the security of operation.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows: a kind of steam heat exchanger that is used to heat, it comprises steam jet pump, motor-driven valve and water pot, its design feature is, described motor-driven valve inlet joins with steam, and the motor-driven valve outlet connects the steam jet pump inlet, and the steam jet pump outlet inserts the water pot top, water pot top connects hot water outlet, and the water pot bottom connects the running water inlet and inserts steam jet pump by stop valve.
According to above-mentioned technical scheme, top and bottom in the described water pot are respectively equipped with temperature sensor, and upper temperature sensor can be controlled motor-driven valve and open.The temperature of lower sensor can control motor-driven valve and cut out.
The present invention has increased water pot owing to adopted said structure, thus hot water circuit and Steam Heating circulation can be separated, thereby big high attenuation changes fluctuation and the influence that system is caused with the delay hot water circulating flow.In addition, employing temperature sensor control motor-driven valve in service need not frequent start-stop steam jet pump and steam regulation valve, and can keep the constant of supply water temperature, has alleviated hand labor intensity greatly.Not only use simple, saving electric energy, and improved operation stability of equipment and security greatly.With the prior art ratio, have reasonable in design, the characteristics of automatic control coefficient height, simple operation.
The invention will be further described below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is a present technique field prior art fundamental diagram;
Fig. 2 is the utility model operation principle and structure connection layout.
The specific embodiment
Referring to Fig. 2, the steam heat exchanger that is used to heat comprises steam jet pump 4, motor-driven valve 5, reaches water pot 2.Motor-driven valve 5 inlets join with steam.Motor-driven valve 5 outlets connect steam jet pump 4 inlets, and steam jet pump 4 outlets insert water pot 2 tops, and water pot 2 tops connect hot water outlet, and water pot 2 bottoms connect the running water inlet and insert steam jet pump 4 by stop valve.Top in the water pot 2 and bottom are respectively equipped with temperature sensor 3 and temperature sensor 1, and temperature sensor 3 can be controlled motor-driven valve 5 and open, and temperature sensor 1 can control motor-driven valve 5 and cut out.
Use among the present invention,, make that the outlet hot water temperature is required hot water temperature when steam jet pump 4 operations by first adjusting.During operation, by the open and close of temperature sensor 3 and temperature sensor 1 control motor-driven valve 5.When measuring point 1 temperature is to prescribe a time limit under the supply water temperature, open control motor-driven valve 5 by temperature sensor 3, the colder water in water pot 2 bottoms is heated to supply water temperature.When measuring point 2 temperature are to prescribe a time limit on the supply water temperature, close motor-driven valve 5 by temperature sensor 1, offer the user by the hot water in the water pot 2.Because cold water is in the bottom of water pot 2 bodies, hot water is on the top of water pot 2 bodies, thereby the layering of water, makes hot and cold water but not mix in a tank body, thus the hot water temperature that assurance is confessed from the top.When the user used hot water, hot water was confessed from the top of water pot 2, simultaneously running water mend from the bottom of water pot 2 into.
