Abstract
The utility model discloses an electric water heater with functions of reverse flow-stopping, dirt-discharging and pressure releasing. The structure of the electric water heater is that the lower bottom surface of a liner body is provided with a cold water inlet joint and a hot water outlet joint, and the two joints are connected with a mixing valve; the cold and the hot water joints in the liner body respectively tilt towards left and right; the lower bottom surfaces of a cold water pipe and a hot water pipe are provided with a dirt-discharging port and connected with a pressure release dirt-discharging valve, wherein, the installing end ports of the cold water pipe and the hot water pipe are close to a top wall. Thus, the utility model has the function of reverse flow stopping, when the pressure of the liner is over large, the utility model can release pressure and discharge dirt in time, so that the service life of the liner body and the heater is extended.
Description
The utility model relates to a kind of electric heater with reverse fluid stopping and blowdown pressure release function.It is the improvement that belongs to electric heater.
The courage body cold water inlet of existing electric heater and hot water outlet pipe are connected in a mixing valve, by the switch and the rotation diverse location of this valve, realize the injection of cold water and the outflow of hot water and mixing water.For preventing aqueous reflux and the safety relief in the courage, a check relief valve is set again on the cold water inlet between hybrid switch valve and the courage body, through facts have proved, this check relief valve has good check and pressure release effect, but in use, finds that it has weak point, be exactly that damage ratio is more serious, often need disassembly, cleaning, dismounting extremely bothers, and makes troubles to the user.
The purpose of this utility model is to provide a kind of electric heater with reverse fluid stopping and blowdown pressure release function.The existing reverse fluid stopping function of this electric heater has the pressure release dirt eliminating function again.
For achieving the above object, the utility model is realized by following proposal.Bottom surface at electric heater courage body, cold water water supply connector and hot water effluent's joint are set, two joints connect the hybrid switch valve outward, the hot water joint connects the hot water outlet pipe of termination near courage body roof that is tilted to the left in the courage body, it is characterized in that, bottom surface at the courage body also is provided with a sewage draining exit, and its external pressure release blowoff valve connects the water inlet pipe of termination near courage body roof that is tilted to the right in the water supply connector of courage body inner cold water.
Below in conjunction with accompanying drawing the utility model is illustrated.
Accompanying drawing is the utility model structural representation.
1 is the courage body among the figure, and 2 is end cap, and 3 is electrothermal tube, and 4 are the pressure release blowoff valve, and 5 is the hot water outlet pipe, and 6 is mixing valve, and 7 is cold water inlet.
Accompanying drawing is analyzed, learn that the utility model has 2 points with the difference of existing electric heater, any is that original reverse flow-stop valve that is connected on the external water inlet pipe of courage is removed, and be to prevent that the water in the courage body from producing backflow phenomenon because of pressure raises, then be provided with the cold water inlet of enough height in the courage body, its benefit is to prevent the refluence of water in the courage.Add a pressure release blowoff valve at courage body bottom surface in addition, play the pressure release effect on the one hand, guarantee safety, regularly blowdown on the other hand, the service life of prolongation courage body and heater.
It is good to the utlity model has the reverse flow-stopping performance, the characteristics that the pressure release dirt eliminating function is complete.
