Abstract

The utility model provides a domestic hanging gas boiler and belongs to the technical field of the heating plant, which is characterized in that a return pipe is connected with the inlet of the heat-exchanger coil; a safety valve and a pressure gauge are arranged on the return pipe; at the same time the return pipe is connected with an expansion tank in parallel; a heating water outlet pipe is connected on the outlet of the heat-exchanger coil; the safety valve and a cross valve are arranged on the heating water outlet pipe; the other outlet of the cross valve is connected with the water inlet of a plate-type heat exchanger; the outlet of the plate-type heat exchanger is connected with the return pipe; the plate-type heat exchanger is connected with the water inlet pipe for the domestic water and the water outlet pipe for the domestic water; a water flow sensor is arranged on the water outlet pipe. The utility model has the advantage that the use operating procedure is simplified through changing automatically. Because the heating water pipeline is different from the domestic water circulating heating pipeline, the situation that the domestic water is polluted by the heating water is avoided and the cleanliness of the use water is increased.

Description

The wall-hanging gas fired-boiler of family expenses

Technical field:

The utility model belongs to the heating plant technical field, relates to a kind of improvement of small-sized household gas fired-boiler.

Background technology:

At present, in the use of small-sized household gas fired-boiler, have two deficiencies, one is that the water channel and the heater of the cycling use of water in the radiator used of domestic water and heating is shared, and heating like this cycling use of water also can be scurried into the domestic water pipeline and be used as domestic water; Another is that manual switchover heating and domestic water need be used valve, complex operation.

Summary of the invention:

Technical problem to be solved in the utility model is:

The wall-hanging gas fired-boiler of family expenses that provides a kind of domestic water and heating cycling use of water to heat use respectively, automatically switch.

The technical solution of the utility model is:

Be connected with return pipe at the heat exchanger coil inlet, on return pipe, be provided with safety valve, Pressure gauge, be parallel with expansion tank simultaneously, be connected with the heating outlet pipe in the heat exchanger coil outlet, the heating outlet pipe is provided with safety valve and triple valve, and another outlet of triple valve connects the heat-exchangers of the plate type water inlet, and the heat-exchangers of the plate type outlet connects return pipe, heat-exchangers of the plate type is connected with the water inlet pipe and the outlet pipe of domestic water, at outlet pipe water flow sensing unit is installed.

The beneficial effects of the utility model are:

By automatic conversion, simplified the use operation sequence, because the heating water is different with domestic water circulation water back, avoided domestic water by heating water pollution condition, improved the cleanliness factor that makes water.

Description of drawings:

Fig. 1 is a structure chart of the present utility model;

Wherein: the 1st, the heating outlet pipe, the 2nd, the combustion gas injector, the 3rd, the combustion chamber, the 4th, heat exchanger coil, 5 collection cigarette cases, the 6th, blower fan, the 7th, flue, the 8th, the heating return pipe, the 9th, the combustion gas air induction conduit, the 10th, water pump, the 11st, gas nozzle, the 12nd, the burnt gas switch valve, the 13rd, expansion tank, the 14th, fire row, the 15th, water inlet control valve, the 16th, the system pressure display list, the 17th, shell, the 18th, main controller, the 19th, safety valve, 20 automatic exhaust steam valves, the 21st, pipeline between heat exchanger coil outlet and the triple valve, the 22nd, triple valve, the 23rd, pipeline between triple valve and the heat-exchangers of the plate type, the 24th, heat-exchangers of the plate type, the 25th, pipeline between heat-exchangers of the plate type and the heating return pipe, the 26th, the life cold water inlet, the 27th, water flow sensing unit, the 28th, the hot water outlet pipe is used in life.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

Wall-hanging gas fired-boiler links to each other with user's cooling system by heating outlet pipe (1), heating return pipe (8), constitutes the heating system of sealing.The automatic control of main controller (18) is issued to unattended automatic unlatching, and temperature is freely set.At first water pump (10) draws in the water of heating system and causes forced circulation in the machine, blower fan (6) starts gas in the body of heater and burnt gas, focus in the cigarette case (5), force to discharge outdoor by flue (7), open burnt gas switch valve (12), natural gas is by combustion gas air induction conduit (9), burnt gas switch valve (12), gas nozzle (11) is ejected in the combustion gas injector (2), and igniting automatically, by fire row (14) in the combustion chamber (3) internal combustion, the heat that produces carries out the extreme misery heat exchange in heat exchanger coil (4), hot water flows out from heating outlet pipe (1) and enters the heat supply of heat radiation heating system.At fireplace and connect expansion tank (13), system pressure display list (16), water inlet control valve (15).When the heating system lack of water, carry out manual moisturizing by water inlet control valve (15), when system pressure display list (16) demonstration reaches 0.15 MPa, just mended full water, need close water inlet control valve (15).In parallel expansion tank (13) decomposes the volume of water expanded by heating in the system, because of the high more water volume of water temperature big more.When water temperature reduced, expansion tank (13) promoted water in the expansion tank by self pressure and flows in the system and go, and makes system fill with water all the time.When producing pneumatosis, system passes through automatic exhaust steam valve (20) discharge system.When system's hydraulic pressure surpasses 0.3 MPa, safety valve (19) is opened pressure release automatically, guarantees security of system.The operation work in airtight shell (17) of whole wall hanging stove, when starting life during with the domestic hot-water, need use the hot water outlet pipe, water-flow signal enters main controller (18) by water flow sensing unit (27) and sends instruction and allows triple valve (22) conversion, heating outlet pipe (1) is closed, pipeline between triple valve and the heat-exchangers of the plate type (23) is opened, and life realizes the partial circulating heating with hot water by heat-exchangers of the plate type (24), water pump (10), heat exchanger coil (4), triple valve (22).Again main controller (18) is received the anhydrous signal of water flow sensing unit (27) during heating, to instruct triple valve (22) conversion, heating water is realized the systemic circulation heating by heating outlet pipe (1), heating return pipe (8), water pump (10), heat exchanger coil (4), triple valve (22).

Claims

1, the wall-hanging gas fired-boiler of a kind of family expenses, it is characterized in that: be connected with return pipe at the heat exchanger coil inlet, on return pipe, be provided with safety valve, Pressure gauge, be parallel with expansion tank simultaneously, be connected with the heating outlet pipe in the heat exchanger coil outlet, the heating outlet pipe is provided with safety valve and triple valve, another outlet of triple valve connects the heat-exchangers of the plate type water inlet, the heat-exchangers of the plate type outlet connects return pipe, heat-exchangers of the plate type is connected with the water inlet pipe and the outlet pipe of domestic water, at outlet pipe water flow sensing unit is installed.
