Description
Technical field
The utility model relates to water heater components technical field, is specifically related to a kind of blowdown assembly.
Background technology
At present, electric heater has become the household electrical appliance generally used in family.Based on safety, the considering of energy-saving and environmental protection angle, anode stub (being generally magnesium rod) is all equipped with in the inner bag of electric heater, for reducing corrosive ions in water body to the infringement of inner bag metal level, delay speed that inner bag metal level is corroded and intensity thus; But anode stub (magnesium rod) limited efficiency, usual one, in two years anode stub (magnesium rod) will disappear by natural volume, need periodic replacement but inevitably can produce incrustation scale in inner bag simultaneously.Therefore, except being provided with into except water interface and water outlet mouthpiece on the inner bag of current electric heater, be also provided with the sewage draining exit for discharging incrustation scale so that cleaning time sewage discharge.
Need during the blowdown of traditional electrical water heater by special tool(s), nut plug to be screwed off, in blowdown process, magnesium rod is also removed, and whole blowdown process is complicated, needs professional to adopt specific purpose tool to operate, moreover, because during blowdown, sewage flashes, and need to wait water temperature in water heater to be reduced to and just can operate without when scald hidden danger human body, the whole blowdown process took time is long, employ manual tools many, easily make dirty clothing and surrounding environment.
Utility model content
The purpose of this utility model is complicated according to existing water heater blowdown process, need the deficiency that professional operates, proposing a kind of blowdown assembly be arranged on bottom water heater, just can carry out simple, the easy to operate blowdown assembly of a kind of structure of blowdown work by rotating blowdown assembly.
The utility model specifically adopts following technical scheme:
A kind of blowdown assembly, comprise magnesium rod bracket, the lower end of described magnesium rod bracket is provided with external screw teeth, the below of described magnesium rod bracket is connected with ball valve shell, described ball valve shell is provided with open slot, the internal sleeve of described ball valve shell has ball valve core, described ball valve shell comprises outer wall and inwall, the top and bottom of described outer wall and inwall are respectively equipped with internal screw thread, the internal screw thread of described outer wall upper end is connected with the external screw teeth of blowdown mouth, the internal screw thread of described inwall upper end is connected with the external screw teeth of magnesium rod bracket lower end, described ball valve core is connected with recessed handles, described recessed handles is stretched out from open slot, the end of described recessed handles is connected with stock, the outside of described ball valve shell is covered with plastics upper cover, the lower end of described plastics upper cover is connected with plastic lower shield.
Preferably, the cover body outer wall of described plastics upper cover is provided with the instruction unit of instruction downwards, be provided with the arrow of instruction downwards in described instruction unit, the cover body outer wall of described plastic lower shield is provided with the display part coordinated with described instruction unit, is provided with month number designation in described display part.
Preferably, described recessed handles is cylindrical.
Preferably, the lower end of described ball valve core is provided with internal screw thread.
Preferably, the upper end of described plastics upper cover is provided with screw hole.
Preferably, the top of described magnesium rod bracket is provided with magnesium rod fixing threaded hole.
The beneficial effect that the utility model has is: be arranged in water heater by this blowdown assembly, structure is simple, easy for installation, the instrument that average family member only need have by means of average families such as screwdrivers, plastics upper cover and plastic lower shield are taken off, stock is connected with by the end of rotating concealed type handle, can by the turn of ball valve core, blowdown is carried out to water heater, only need turn recessed handles again after blowdown or end-of-job, ball valve core can be closed again, water heater is normally worked, convenient and swift, simple to operation.
