Abstract
The utility model relates to an emptying device of water duct of water heater, including a water tank, one-way valve, control valve and water duct, and the water tank is provided with an exhaust port, the control valve is assembled between the water tank and the water duct and is connected with an air pipe through the one-way valve, and the air pipe arranged inside the water tank is communicated with the exhaust port. The utility model overcomes the defects which the air pipe and drain in the prior emptying device of water duct of water heater ices up easily and is arranged and saves temperature inconveniently, and meanwhile the auxiliary components are difficultly assembled, so that the air pipe in the emptying device of water duct of water heater is positioned in the water tank upward and is exhausted by the high-temperature air in the water tank and will not contact with the outside atmosphere directly to prevent icing; the utility model has the advantages of simple structure, convenient assembly and good thermal insulation effect.
Description
The utility model relates to a kind of water heater water-supply-pipe emptier.
Breather pipe in traditional water heater water-supply-pipe emptier all passes through check valve, control valve and water-supply-pipe and links to each other, breather pipe directly exposes in air, utilizes extraneous cold air to carry out emptying, under the northerly severe cold, the ventilation drainpipe easily freezes, and influences the normal use of water heater.And it is oversize to be assemblied in being connected of outer check valve of water tank and control valve, installs, insulation is very inconvenient.In addition, when servicing unit such as water-temperature water-level demonstration need be installed when water heater, can only insert from the exhaust outlet on water tank next door or at water tank bottom installing hole is set again, like this, will influence the global shape and the heat insulation effect of water heater.
The purpose of this utility model is that the ventilation drainpipe that solves existing water heater water-supply-pipe emptier existence easily freezes, installs, is incubated problem inconvenient, that accessory is difficult to assemble.The utility model comprises water tank, check valve, control valve and water-supply-pipe, and water tank is provided with exhaust outlet, and control valve is assemblied between water tank and the water-supply-pipe, and control valve connects breather pipe by check valve, breather pipe be arranged in the water tank and with exhaust outlet UNICOM.
Breather pipe and check valve all are assemblied on the valve seat of control valve.
Be provided with the water-temperature water-level display part in the water tank, the end of water-temperature water-level display part is fixed on the valve seat of control valve equally.
The utility model is by above-mentioned specific design, breather pipe in the water heater water-supply-pipe emptier is arranged in the water tank up, utilizes the high temperature air in the water tank to carry out emptying, directly do not contact with ambient atmosphere, prevent to freeze, have advantage simple in structure, easy to assembly, high insulating effect.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises water tank 1, check valve 2, control valve 3 and water-supply-pipe 4, and water tank 1 is provided with exhaust outlet 5, and control valve 3 is assemblied between water tank 1 and the water-supply-pipe 4, control valve 3 connects breather pipes 6 by check valve 2, breather pipe 6 be arranged in the water tank 1 and with exhaust outlet 5 UNICOMs.Breather pipe 6 and check valve 2 all are assemblied on the valve seat 7 of control valve 3.Be provided with water-temperature water-level display part 8 in the water tank 1, the end of water-temperature water-level display part 8 is fixed on the valve seat 7 of control valve equally.When carrying out the emptying operation, B mouth 9 in the control valve 3 communicates with C mouth 10, open indoor valve after, water-supply-pipe 4 is communicated with atmosphere, produce negative pressure, check valve 2 is opened, and extraneous air enters water tank 1 through exhaust outlet 5, and enters B mouth 9 and C mouth 10 behind breather pipe 6, check valve 2, be that B mouth 9 communicates with ambient atmosphere, under the atmospheric effect in the external world, the water in the water-supply-pipe 4 flows out, and reaches the purpose of emptying water-supply-pipe 4.
