Abstract
The utility model relates to boiler circulating water systems and in particular relates to a boiler with a device capable of automatically regulating a flow rate of circulating water, and the boil can be used for solving the problem of a pumping-out or overflow situation in the existing boiler circulating water system. The boiler with the device capable of automatically regulating the flow rate of the circulating water comprises a boiler body, a small water tank, a water pump and a water storage tank, wherein the water outlet of the water storage tank is connected with the water return port of the boiler through a water return pipe; the water return pipe is provided with a butterfly valve; the butterfly valve comprises a valve seat, a disk plate and a valve rod, wherein the disk plate is arranged in the shaft hole of the valve seat, and the valve rod is fixed on the disk plate after penetrating through the valve seat; and a floating ball is arranged in the small water tank, a connecting rod is vertically fixed with the floating ball, the other end of the connecting rod is vertically fixed with the valve rod of the butterfly valve. By utilizing the device of the boiler disclosed by the utility model, the water yield and water return amount of the boiler are dynamically balanced, thus the boiler disclosed by the utility model can be widely applied to the boiler circulating water systems.
Description
Technical field
The utility model relates to the boiler water recycling system, is specially the boiler that has automatic adjusting cycling use of water flow apparatus.
Background technology
In the existing boiler water recycling system, the water inlet of boiler links to each other with little water tank, and the delivery port of boiler links to each other with storage tank through water pump, and the delivery port of storage tank links to each other with the water return outlet of boiler through return pipe.Water during work in the boiler is extracted out through water pump and is got into storage tank, and the water in the storage tank flow back in the boiler through return pipe again.The problem that the mode of this circular flow exists is that the water outlet and the backwater of boiler must balance be that flow equates, otherwise the circulatory system just is difficult to normal operation.In boiler water recycling system when design,, the diameter of return pipe is greater than the diameter of outlet pipe (being the cross section flow that the cross section flow of return pipe is greater than outlet pipe).When circling water flow rate hour, vaccuum phenomenon can appear in the water in the boiler; And when the backwater amount was big, the spilling water phenomenon can appear in the little water tank that links to each other with the boiler feed water mouth.
Summary of the invention
The utility model can occur in the existing boiler water recycling system finding time or the problem of spilling water phenomenon in order to solve, and the boiler that has automatic adjusting cycling use of water flow apparatus is provided.
The utility model is to adopt following technical scheme to realize: have the boiler of automatic adjusting cycling use of water flow apparatus, comprise boiler body, little water tank, water pump and storage tank; The delivery port of storage tank links to each other with the water return outlet of boiler through return pipe; Return pipe is provided with butterfly valve; The valve rod that butterfly valve comprises valve seat, is located at the dish plate in the valve seat axis hole and passes valve seat and the dish plate is fixing; Be provided with ball float in the little water tank, vertical fixing has connecting rod on the ball float, the valve rod vertical fixing of the other end of connecting rod and butterfly valve.During work, because of little water tank links to each other with the water inlet of boiler, so little water tank is equal with the water level of boiler; When the water level in the little water tank rises, explain that the backwater amount is big, ball float rises along with the rising of little cistern water level, and the valve rod that the fly rod of ball float drives butterfly valve rotates, and makes butterfly valve turn down thereby drive with the fixing dish plate upset of valve rod; When the water level in the little water tank descends, explain that the backwater amount is little, ball float descends along with the decline of little cistern water level, and the valve rod that the fly rod of ball float drives butterfly valve rotates, and makes butterfly valve open greatly thereby drive with the fixing dish plate upset of valve rod; So just through the automatic adjusting of boiler water recycling system being reached the flow equilibrium of outlet pipe and return pipe, avoid occurring the phenomenon of finding time or overflowing.
The described device of the utility model makes the water yield of boiler and backwater amount reach dynamic equilibrium, solves can to occur in the existing boiler water recycling system finding time or the problem of spilling water phenomenon, can be in the boiler water recycling system.
