The automatic water feeding device for a steam boiler comprises a water storing cavity, a boiler water complementing pipe positioned below the water storing cavity. The utility model is characterized in that the upper part of the water storing cavity is provided with a water inlet cavity, and the water storing cavity is communicated with the water inlet cavity through a water inlet isolating valve; a water inlet one-way valve is arranged on the cavity wall of the water inlet cavity, wherein, the top of which is provided with a steam pernetrating valve. The utility model is communicated with a running water pipe without the need of an electric pump to realize automatic water feeding, and the utility model has the advantages of simple structure, little power consumption and rapid air venting.
Description
The utility model belongs to the steam boiler auxiliary equipment, relates to intake the automatically technical scheme of device of a kind of pump-free type steam boiler.
Existing miniature boiler adopts manually to add water in advance as the small steam boiler in laundering shop, seals boiler then the mode that whole water storages heat is produced steam, add that water needs earlier will boiler cool off, could add after the emptying if replenish again, troublesome poeration not only, and it is slow to go out vapour, and energy consumption is big.The large-sized boiler water supply system generally all is equipped with the water pump pressurizing feedwater, if adopt the system of dry pump feedwater, structure bulky complex, energy consumption are big, and their economy all is not suitable for miniature boiler.
The purpose of this utility model is to overcome the weak point that existing small steam boiler adds water inconvenience aspect, by improvement to small steam boiler water supply system structure, and the technical scheme that provides a kind of pump-free type steam boiler to intake device automatically.
The purpose of this utility model is achieved by the following technical solution, the steam boiler device of intaking automatically, comprise water storage cavity and the boiler replenishing water pipe that is positioned under the water storage cavity, it is characterized in that water storage cavity top is provided with intake antrum, water storage cavity is communicated with by isolating valve with intake antrum, intake antrum chamber wall is provided with into water check valve, and the intake antrum top is provided with steam valve.
The described steam boiler device of intaking automatically also is provided with pressure-equalizing pipe between water storage cavity and intake antrum, two openends of pressure-equalizing pipe lay respectively at the bottom avris of intake antrum and the bottom avris of water storage cavity.
The described steam boiler device of intaking automatically, water storage cavity is arranged on the top of steam boiler, and filling pipe stretches into the bottom of steam boiler.
The described steam boiler device of intaking automatically, isolating valve, saturating steam valve all are the balloon-like structure that outer tube, interior float cooperate.
The described steam boiler device of intaking automatically, the open top that it is characterized in that outer tube is a circular hole, and the bottom opening of outer tube is a square hole, and Circularhole diameter, the square hole length of side are all less than the float diameter.
The described steam boiler device of intaking automatically, the float lower end of saturating steam valve hangs a ball float by fine rule.
This steam boiler device of intaking is automatically connected with running water pipe, need not electric pump, realize adding water automatically, and simple in structure, little power consumption, it is fast to give vent to anger.Being particularly suitable for the small steam boiler uses.
Further specify the utility model and provide embodiment below in conjunction with Figure of description.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model isolating valve structural representation.
As shown in the figure, the steam boiler device of intaking automatically comprises water storage cavity 7 and is positioned at boiler replenishing water pipe 1 under the water storage cavity 7 that water storage cavity 7 designs have a constant volume, are arranged on the top of steam boiler 9, and filling pipe 1 is a tubule, stretches near the bottom of steam boiler 9.Water storage cavity 7 tops are provided with one and the intake antrum 5 of cavity separation, water storage cavity 7 is communicated with by isolating valve 3 with intake antrum 5,5 of water storage cavity 7 and intake antrums also are provided with pressure-equalizing pipe 2, and two openends of pressure-equalizing pipe 2 lay respectively at the bottom avris of intake antrum 5 and the bottom avris of water storage cavity 7.The chamber wall is provided with the water inlet check valve of connecting with running water pipe 6 near intake antrum 5 bottoms, and intake antrum 5 tops are provided with steam valve 4.Isolating valve 3, saturating steam valve 4 all are the balloon-like structure that outer tube 12, interior float 13 cooperate, and the open top of outer tube 12 is a circular hole, and the bottom opening of outer tube 12 is a square hole, and Circularhole diameter, the square hole length of side are all less than the diameter of float 13.Float 13 lower ends of saturating steam valve 4 hang a ball float 11 by fine rule 10.
When using steam boiler 9, at first close boiler gas outlet valve 8, open the running water halter, use steam boiler 9 first, after a few minutes of need waiting, the energising heating; The heating of can directly switching on of use later on.Saturating steam valve 4, isolating valve 3 are when anhydrous no vapour, interior float 13 is positioned on the square hole of sleeve pipe 12 bottoms, saturating steam valve 4, isolating valve 3 are opening state, intake antrum 5, water storage cavity 7 internal gas pressures are atmospheric pressure, running water can enter intake antrum 5 by water inlet check valve 6, through isolating valve 3, filling pipe 1 enters boiler 9 bottoms again.Inflow gradually along with running water, boiler 9 bottoms level improve gradually, the space on boiler 9 tops reduces gradually, boiler 9 bottom liquids are heated simultaneously, and the air pressure of boiler 9 upper spaces increases gradually, and running water begins to be full of gradually water storage cavity 7, during water storage cavity 7 approaching being full of, because the ratio water of float 13 designs in the isolating valve 3 is heavy slightly, as the glass marble float, at this moment, float 13 in the isolating valve 3 can not float, liquid overflows into intake antrum 5 by isolating valve 3 in the water storage cavity 7, because the ratio water of float 13 designs in the saturating steam valve 4 is light slightly, as the ball float, when running water is full of intake antrum 5, float in the saturating steam valve 4 floats, and closes steam valve 4, and running water is not flowing into.Use along with steam, the water level of intake antrum 5 descends, and the deadweight of ball float 11 is withdrawn into the float 13 in the saturating steam valve 4 on the square hole of sleeve pipe 12 bottoms by fine rule 10, and saturating steam valve 4 is opened, intake antrum 5 upper spaces communicate with atmosphere, air pressure descends, the float 13 in the isolating valve 3 under pressure reduction and buoyancy function, the circular hole at closed casing 12 tops, steam in water storage cavity 7 and the boiler 9 can not overflowed, at this moment, in the pressure-equalizing pipe 2 liquid flow is arranged, the pressure reduction of partial equilibrium water storage cavity 7 and intake antrum 5.When saturating steam valve 4 was opened, water inlet check valve 6 can be opened, and running water flows into after intake antrum 5 upper spaces are full of, and saturating steam valve 4 is closed again and stops into water.Float 13 in the isolating valve 3 can be got back to again on the square hole of sleeve pipe 12 bottoms, and boiler 9 is able to automatic water supplement, can work on incessantly.After stopping steam supply, only need boiler 9 outages to get final product.
