In order to achieve the above purposes, the technical solution adopted by the utility model is: it include water-heater water tank, metal steel pipe,
Triple valve, air hose, upper and lower conduit, air conducting valve, water mixing valve, connection hose, cut-off electromagnetic valve, drain valve；Institute
Metal steel pipe is plugged among the upper end for the water-heater water tank stated, the upper end of metal steel pipe is connected with triple valve, point of triple valve
It is not connect with air hose, upper and lower conduit, air hose tail portion is connect with air conducting valve, and the lower end of upper and lower conduit is mixed with hot and cold water
Valve connection, and water mixing valve both ends are parallel with connection hose, connect and connect between the lower end of hose and tap water water inlet end
There is cut-off electromagnetic valve, is connected with drain valve on the right side of cut-off electromagnetic valve.
Preferably, the inside of the water-heater water tank is plugged with liquid level sensor, and set on the side wall of upper and lower conduit
It is equipped with temperature sensor.
Preferably, the air conducting valve, cut-off electromagnetic valve, drain valve, liquid level sensor and temperature sensor are equal
It is connect with measurement and control instrument.
Preferably, air conducting valve unlatching close synchronously synchronous with drain valve.
After adopting the above structure, the utility model has the beneficial effect that a kind of water heater described in the utility model with two-tube
Formula pipeline evacuation structures, its area of application is extensive, affected by environment small, stable and reliable for performance, effectively avoids valve body leak
Unfavorable factor, and air valve and drain valve are installed in interior, have the characteristics that easy to maintain, long service life, thoroughly solve
The problem of scale and leak freeze.The advantages that the utility model has structure simple, and setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols:
Water-heater water tank 1, metal steel pipe 2, triple valve 3, air hose 4, upper and lower conduit 5, air conducting valve 6, hot and cold water are mixed
Close valve 7, connection hose 8, cut-off electromagnetic valve 9, drain valve 10, measurement and control instrument 11, liquid level sensor 12, temperature sensor 13.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, present embodiment adopts the following technical scheme that it includes water-heater water tank 1, metallic steel
Pipe 2, triple valve 3, air hose 4, upper and lower conduit 5, air conducting valve 6, water mixing valve 7, connection hose 8, cut-off electromagnetic valve
9, drain valve 10；Metal steel pipe 2 is plugged among the upper end of the water-heater water tank 1, the upper end of metal steel pipe 2 is connected with
Triple valve 3, triple valve 3 are connect with air hose 4, upper and lower conduit 5 respectively, and 4 tail portion of air hose is connect with air conducting valve 6, on
The lower end of downcomer 5 is connect with water mixing valve 7, and 7 both ends of water mixing valve are parallel with connection hose 8, connect hose 8
Lower end and tap water water inlet end between be connected with cut-off electromagnetic valve 9, drain valve 10 is connected on the right side of cut-off electromagnetic valve 9.
Wherein, the inside of the water-heater water tank 1 is plugged with liquid level sensor 12, and sets on the side wall of upper and lower conduit 5
It is equipped with temperature sensor 13；Air conducting valve 6, cut-off electromagnetic valve 9, drain valve 10, liquid level sensor 12 and the temperature passes
