Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, safety and stability, and use and control water heater preheating device easily.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of water heater preheating device, be connected with the domestic water pipeline with the cycling use of water pipeline, it is characterized in that: it comprises housing and inner tube connector, water circulating pump, storage pressure device, water flow sensing unit, temperature-sensing probe and the controller that is provided with thereof, water circulating pump has automatic exhaust device, and water flow sensing unit and temperature-sensing probe are separately positioned on the peripheral of tube connector and are connected with controller.
As further specifying of such scheme, described water flow sensing unit and temperature-sensing probe are installed on respectively on the tube connector, and this tube connector links to each other with water pump.
Described housing is provided with water supply connector and backwater joint, and an end of two joints connects the tube connector of enclosure interior, and the other end connects domestic water pipeline and cycling use of water pipeline respectively.
Be connected with three-way body between described water supply connector and the backwater joint, this three-way body includes two check valves, will converge circulating backwater and living water in one the tunnel.
Described storage pressure device adopts expansion drum, and the input of expansion drum links to each other with backwater joint by tube connector.
The sidepiece of described backwater joint is provided with the cleaning bolt, and water-quantity regulating device is housed in the water supply connector.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts water circulating pump, expansion drum, water flow sensing unit, critical piece such as temperature-sensing probe and controller, add tube connector, three-way body, water supply connector, backwater joint, the common organic whole of forming, with the supporting use of water heater main frame, be installed between water pipeline and the inlet pipeline, make the water circular flow in the system pipeline, start water heater, water in the heating pipe line, thus the water in the system pipeline is maintained certain temperature range, realize instant maintenance water temperature, whole day preheating in 24 hours makes the interior water temperature of heat supply waterpipe maintain uniform temperature, realize promptly opening that hot water is promptly arranged, needing to avoid emptying cold water.
2, water circulating pump of the present utility model has automatic exhaust device, and the air in the discharge pipe automatically in the trial run of system and warm prevents to produce resonance and water pump dallies because of air.

Description of reference numerals: 1, housing 2, tube connector 3, water circulating pump 4, storage pressure device 5, water flow sensing unit 6, temperature-sensing probe 7, controller 8, automatic exhaust device 9, backwater joint 10, water supply connector 11, three-way body 12, check valve 13, cleaning bolt 14, water-quantity regulating device
The specific embodiment
As Fig. 1～shown in Figure 4, the utility model water heater preheating device, be connected with the domestic water pipeline with the cycling use of water pipeline, it comprises housing 1 and the inner tube connector 2 that is provided with, water circulating pump 3, storage pressure device 4, water flow sensing unit 5, temperature-sensing probe 6 and controller 7, and controller 7 connects the control system of water heater main frame; In the present embodiment, the storage pressure device adopts expansion drum in order to keep hydraulic pressure in the system pipeline in certain scope.Wherein, water circulating pump 3 is core components of preheating device, circulation power is provided, water circulating pump 3 has automatic exhaust device 8, the air in the discharge pipe automatically in the trial run of system and warm, prevent to produce resonance because of air, prevent that water pump is stuck, idle running, water flow sensing unit 5 and temperature-sensing probe 6 are separately positioned on the peripheral of tube connector 2 and link to each other with controller 7, it feeds back to the temperature signal of water-flow signal and system water in the controller 7 of preheating device, feed back in the control system of water heater main frame by controller 7 again, as the basis for estimation of central hot-water heating system work.Housing 1 is provided with backwater joint 9 and water supply connector 10, two joints connect cycling use of water pipeline and domestic water pipeline respectively, the input of expansion drum links to each other with backwater joint 9 by tube connector 2, and the sidepiece of backwater joint 9 is provided with cleaning bolt 13, and water-quantity regulating device 14 is housed in the water supply connector 10.Be connected with three-way body 11 between water supply connector 10 and the backwater joint 9, will converge circulating backwater and living water in one the tunnel, this three-way body 11 includes two check valves 12, guarantees that recirculated water can not enter water supply line, and living water can not reversely enter circulation line.
In control, preheating device and water heater main frame are a unified integral body, temperature, the water-flow signal of preheating device gathering system water, signal feedback is given the control system of main frame, analyzed, calculated by main frame, send instruction then, whether commander's preheating device moves.
During use,, make the water circular flow in the system pipeline with preheating device and the supporting use of water heater main frame, start water heater, system water is heated, and temperature raises, volumetric expansion, part water enters in the expansion drum, and the hydraulic pressure of system is alleviated, and avoids producing too high hydraulic pressure, prevent that system pipeline, water heater and preheating device are destroyed, descend in the system water temperature, in pressure decreases, the water in the expansion drum is extruded in the return pipe road, keeps the hydraulic pressure in the system pipeline; When the water in the system pipeline reach required temperature is set after, preheating device is with out of service, and water heater stops heating, and the water in the system pipeline maintains certain temperature range thus, even in the winter of cold, can use warm water as long as no matter at any time open with penstock.
