End outside, and the upper end of upper valve is connect by upper and lower conduit with water mixing valve, the both ends of water mixing valve pass through two
Group triple valve parallel connection is connected by connection hose and is connected with cut-off electromagnetic valve between the lower end of hose and tap water water inlet end, is ended
Drain valve is connected on the right side of solenoid valve.
Preferably, the inside of the water-heater water tank is plugged with upper liquid level sensor and temperature sensor；On and
It sets liquid level sensor and temperature sensor is connect with measurement and control instrument.
Preferably, upper valve, cut-off electromagnetic valve and the drain valve is connect with measurement and control instrument, and upper valve and draining
It is interlock logic between valve.
After adopting the above structure, the utility model has the beneficial effect that a kind of water heater single tube described in the utility model
Formula pipeline evacuation structures, its area of application is extensive, affected by environment small, and improve solar water heater makes in China northern territory
With rate, the unfavorable factor of valve body leak is effectively avoided, and single tube installation is mounted directly without changing water heater original structure
, long service life.The advantages that the utility model has structure simple, and setting is reasonable, low manufacture cost.
