Description

The conversion equipment of domestic hot water's heating device

Technical field the utility model relates to a kind of pot-type boiler.

It is many that background technology utilizes domestic gas-fired water heater to have as the design of heating plant thermal source at present, as on October 22nd, 1997 utility model patent communique disclosed a kind of＜domestic hot water's heating device (patent No. 96239529.3) its primary structure includes hot water circulation loop and temperature control system.Wherein hot water circulation loop is to adopt existing gas heater as thermal source, by water pipe it and radiator, water pump, water tank are cascaded and constitute, temperature control system is composed in series by two temperature controllers, temperature sensor probe places respectively in radiator air port and the gas heater outlet water pipe, its weak point is if desired during domestic water, what use is recirculated water on the hot water circulation loop, does very unhygienic like this; Recirculated water all bled off annotate new water again, do and cause the waste of water resource like this.

Summary of the invention the utility model mainly is on the loop that is made of gas heater, water pump, radiator, water tank (also can not establishing), establishes the conversion equipment of domestic water and heating recirculated water.This conversion equipment mainly is a solenoid directional control valve.Two mutual disconnected cavitys are arranged in this valve body, and one of them chamber is an intake antrum, and another chamber is a drain chamber, and a pair of valve seat at regular intervals is respectively established at each middle part, chamber, is provided with the valve block corresponding with valve seat between two valve seats, and two valve blocks all are fixed on the valve rod.This valve rod passes two valve pockets and two ends are positioned at outside the valve body, and the one end is provided with spring, and the other end is provided with coil, and this coil links to each other with water pump by lead.Respectively establish an interface on the valve body in above-mentioned each chamber outside two valve seats, and be located at that two pairs of interfaces on the valve body of valve seat the same side all link to each other with the water pipe of same system as: the interface on the valve body of every pair of valve seat left side, two chambeies links to each other with water service pipe, just so the interface on the every pair of valve seat right side valve body links to each other with the heating circulating water pipe.And intake antrum left side valve body interface is to be that running water pipe links to each other with the water inlet of domestic water, and intake antrum right side valve body interface is to be that return pipe links to each other with the water inlet of heating recirculated water.In like manner, water chamber left side valve body is to be that the domestic hot-water manages and links to each other with the water outlet of domestic water, and water chamber right side valve body is to be that the circulating hot water pipe links to each other with the water outlet of heating recirculated water.Respectively establish an interface in addition on the valve body between two pairs of valve seats of reversal valve, the interface that wherein is located on the intake antrum links to each other with the gas heater cold water inlet, and the interface that is located on the water chamber can link to each other with the gas heater hot water outlet.

Above-mentioned solenoid directional control valve valve block in the normal state seals the valve seat corresponding with establishing heating recirculated water interface, makes domestic water system constitute path, and the heating circulation disconnects.When needs heating, connect power supply, the electromagnetic switch valve coil just makes valve rod to coil one side shifting, and the valve block on the valve rod is also synchronously towards coil one side shifting, valve block is sealed the valve seat corresponding with establishing the domestic water interface, so domestic water system disconnects, the heating circulation constitutes path.When connecting power supply, the water pump of heating circulation is also started working, and whole like this heating system is just carried out work.When hot water use in needs lives, be located at the pressure switch that the water heater on the domestic water pipeline carries, to open owing to water pressure release pressure switch, this pressure switch is connected with solenoid directional control valve and water pump lead again, so solenoid directional control valve and water pump all quit work.Its coil of solenoid directional control valve no power just loses magnetism.Valve rod returns to original state with it under spring action, i.e. the conducting domestic water system.Above-mentioned solenoid directional control valve can be directly installed on the loop of being made up of water heater, water pump, radiator, also can form a fixing module with water pump and controller, and promptly a product independently uses with convenient.

The utility model is used for the loop be made up of water heater, water pump, radiator, and heating, domestic water can freely be changed, and is easy and simple to handle.

Description of drawings

Fig. 1 is the utility model user mode simplified schematic diagram.

Fig. 2 is the section simplified schematic diagram of the utility model solenoid directional control valve.

The specific embodiment is in the conversion equipment user mode schematic diagram of domestic hot water's heating device shown in Figure 1, and it comprises the loop that is made of the gas heater 2 that carries pressure switch 1, radiator 3, water pump 4, is provided with solenoid directional control valve 5 on above-mentioned loop.In the section simplified schematic diagram of the utility model solenoid directional control valve shown in Figure 2, two mutual disconnected cavitys are arranged in the valve body, a pair of valve seat at regular intervals 5 is respectively established at middle part, each chamber, all is fixed on the valve rod 8 being provided with valve block 7, two valve blocks between two valve seats.This valve rod passes two valve pockets, and two ends are positioned at outside the valve body, and tool one end is provided with spring 8, and the other end is provided with coil 10.Respectively establish an interface on the valve body outside two valves are used in above-mentioned each chamber, and being located at two pairs of interfaces on the valve body of valve seat the same side all links to each other with the water pipe of same system, interface on the valve body of every pair of valve seat left side of two valve pockets links to each other with water service pipe 11,12, and the interface on the every pair of valve seat right side valve body links to each other with heating circulating water pipe 13,14.And intake antrum left side valve body interface is to link to each other with running water pipe, and intake antrum right side valve body interface is to link to each other with the return pipe of heating cycling use of water.In like manner, water chamber left side valve body is to manage with the domestic hot-water of domestic water to link to each other, and water chamber right side valve body is to link to each other with the circulating hot water pipe of heating recirculated water, and the conduit that links to each other with above-mentioned solenoid directional control valve is provided with unidirectional non-return valve 15.On the valve body between two pairs of valve seats of reversal valve, respectively establish an interface that links to each other with the gas heater gateway respectively in addition, the interface that wherein is located on the intake antrum can link to each other with gas heater cold water inlet pipe, and the interface that is located on the water chamber can link to each other with the gas heater hot water outlet pipe.In Fig. 1, establish the temperature sensor 17 that links to each other with controller 10 on the conduit before the water pump suction inlet again.
