The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is:
A kind of storage-type electric water heater detects the inner liner pressure device automatically; Comprise water pressure detector, magnetic valve, controller and master control substrate; Said water pressure detector can detect electric heater water pipe internal water pressure and inner container of electric water heater internal water pressure; And detected pressure signal is transferred to the master control substrate, and the master control substrate is transferred to controller with the pressure signal that receives with the form of the signal of telecommunication, and controller compares the said signal of telecommunication and rated pressure value; And the break-make through heater in the comparing result control inner container of electric water heater, thereby control inner container of electric water heater internal pressure increases with the rising of water temperature; The feedback signal that said magnetic valve can receive the Self Control substrate to return, and according to the break-make of said feedback signal control magnetic valve.The water pressure detector can detect electric heater water pipe internal water pressure; And hydraulic signal in the detected water pipe is transferred to the master control substrate; The master control substrate is transferred to controller with hydraulic signal in the water pipe that receives with the form of the signal of telecommunication; Controller can be analyzed the signal of telecommunication that receives, and controls the break-make of magnetic valve through analysis result, thereby controls the break-make of current in the electric heater water pipe.Long-time anhydrously flow through out-of-dately when the water pressure detector detects in the water pipe, magnetic valve will cut out under the control of controller automatically.
Be provided with display, said water pressure detector links to each other with the master control substrate through being electrically connected, and said magnetic valve links to each other with the master control substrate through being electrically connected, and said master control substrate links to each other with controller through being electrically connected, the output of controller control display.
Be provided with safety valve; Form hose nozzle on the electric heater body, said water pressure detector upper end is connected with the hose nozzle of electric heater, and the lower end is connected with said safety valve upper end; The safety valve lower end links to each other with the upper end of magnetic valve, and the magnetic valve lower end links to each other with cold water pipeline water out adapter.Safety valve is too high in the inner container of electric water heater internal pressure, when reaching its decompression protection pressure, can open pressure release automatically, and the protection inner container of electric water heater damages.
The upper end of said water pressure detector, magnetic valve and safety valve is female thread structure, and the lower end is external thread structure.
Said display is located on the controller, shows the water pressure value.
Said electric heater water pipe is the electric heater water inlet pipe.
The useful technique effect of the utility model is: this device adopts water pressure detector and controller to detect control electric heater water pipe internal water pressure and inner bag internal water pressure; The force value and the rated pressure value that detect are compared; And pass through the break-make that comparing result is controlled heater in the inner container of electric water heater, can prevent that the inner container of electric water heater internal pressure is too high; Adopt magnetic valve to receive the feedback signal of Self Control substrate, and according to the break-make of feedback signal control magnetic valve, can prevent the leak generation of situation of antipriming pipe; Adopt water pressure detector instead discharge detector, minimizing has flow restriction because of the discharge detector, and is easy in impurity obstruction in the running water, thereby causes the phenomenon of machine system fault.
