Abstract
The utility model relates to the technical field of heating, and particularly relates to a boiler high differential pressure balance water tank. A differential pressure balance expansion water tank is arranged at water outlet pipelines of a first boiler and a second boiler, a differential pressure balance water supplementing pipe of the differential pressure balance expansion water tank is connected with a first water outlet pipeline of a circulating pump, and a differential pressure balance pipeline of the differential pressure balance expansion water tank is connected with a first water inlet pipeline of the circulating pump. The boiler high differential pressure balance water tank is advantageous in that an enclosed expansion water tank is additionally arranged at the water outlet pipelines of the boilers, and a water pipe is additionally arranged in the middle of the enclosed expansion water tank to be connected with a water pump water inlet, so that the water outlet pressure of the boilers and the water inlet pressure of a water pump are matched and air can be prevented from entering into the boilers. The boiler high differential pressure balance water tank is simple in structure, low in cost, good in operation, high in heat efficiency, less in water charging frequency, and stable in pressure, and eliminates false pressure, as well as guarantees the safe operation of the boilers. The water tank provided is applicable to hot water boilers.
Description
Technical field
The utility model relates to heating technology field, specifically relates to a kind of improved boiler high-level pressure balance water tank.
Background technology
Existing 2 tons of hot-water boilers burn and find to exist following defect through examination: 1, boiler pressure gauge instruction is unstable, 2, boiler and heating system have large quantity of air, air enters pipeline, undesired and the boiler of boiler pressure can not moisturizing, after Bas Discharged, cause again boiler water shortage, have a strong impact on safe operation of the boiler.3, heating system leaks seriously, 4 artifical water heights, and false pressure phenomenon, makes the boiler operatiopn time long, and number of water is ordinary, and the thermal efficiency is low, and the wasting of resources is large, more seriously affects the safe operation of boiler.Exist the main cause of these problems to be; Pipe network circuit is long, curved many, the many resistances of system are large, and pipe network circuit does not match to water circulation is connected bad with water circulating pump, and expansion tank is in the past uncovered, be arranged on the end of pipe network, mainly play expansion, pressure reduction is excessive, when pump operating cycle, suck large quantity of air from heating system air bleeding valve, air enters circulating pump, and water does not circulate, etc. problem be all that the excessive water circulation of pressure reduction is bad caused.And existing pipe network is transformed, not only can't resolve problem, also can cause company's fund waste.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency existing for prior art, provides one to can be boiler operatiopn supercharging, exhaust, expansion, and can be boiler and dwindle pressure reduction, prevents that air from entering the boiler high-level pressure balance water tank of boiler.
A kind of boiler high-level pressure balance of the utility model water tank is achieved by following technical proposals: a kind of boiler high-level pressure balance of the utility model water tank comprises heating system, heating water outlet pipeline, water supply tank, heating water return pipeline, No. 1 boiler, No. 2 boilers, the water outlet pipeline installing pressure balance expansion tank of No. 1 described boiler and No. 2 boilers; The pressure balance filling pipe of described pressure balance expansion tank is connected with the first water outlet pipeline of circulating pump, and the pressure balance pipeline of pressure balance expansion tank is connected with the first back with water inlet line of circulating pump.
A kind of boiler high-level pressure balance of the utility model water tank has following beneficial effect compared with prior art: the utility model is to install a closed expansion tank that adopts steel plate to make 1000 × 1000 × 1000mm additional at boiler discharging tube line place, and be connected to pump intake at sealing expansion tank middle part increase by one φ 50 water pipes, the intake pressure of boiler discharge pressure and water pump is matched, enter boiler thereby stop air.High-order pressure balance expansion tank of the present utility model is closed with pressure, the pressure balance filling pipe effect being connected on circulating pump water outlet pipeline is supercharging, exhaust, expand etc., the pressure balance pipeline effect being connected in circulating pump back with water inlet line is secondary moisturizing, diversion, dwindles pressure reduction, prevents that air from entering boiler etc.A kind of boiler high-level pressure balance of the utility model cisten mechanism is simple, and cost is low, and operational excellence has improved the thermal efficiency, has reduced number of water, and pressure stability has been eliminated false pressure, has ensured safe operation of the boiler.A kind of boiler high-level pressure balance of the utility model water tank can be applicable to hot-water boiler.
