Hot water circulation promotion device of hot water boiler

1 is a perspective view of the present invention.

2 is a cross-sectional view showing a pipe state of the present invention.

The present invention is to install the water supply pipe at the top of the water pipe and the water pipe to be circulated from the water pipe of the hot water boiler to the water supply pipe through the hot water circulation pipe to the upper position than the boiler body in the water supply tank to the hot water level control tank in the water supply pipe When the hot water flows into the hot water level regulator by the pressure of the heated hot water, the level of hot water in the hot water level regulator rises and then the water level in the hot water level regulator drops and pushes the hot water in the hot water circulation pipe. In order to circulate the hot water circulation pipe horizontally in order to forcibly circulate the cold water having a relatively low pressure in the hot water circulation pipe, the hot water circulation is not good unless the horizontal water pipe is constructed horizontally. Steam and air circulate with the hot water in the tube, so any part of the hot water circulation tube If the pipe is bent in a way that the steam and air stays in the bent portion because it blocks the hot water circulation path is a lot of defects that interfere with the hot water circulation.

The present invention is intended to solve such a conventional defect, it will be described in detail based on the accompanying drawings as follows.

In the case where the drain pipe 2 and the water supply pipe 3 are installed on one side of the boiler body 1 and the water supply tank 4 is installed at the upper end thereof, the hot water level control tank 5 is built in the water supply tank 4 to drain the water pipe. In communication with (2), the steam exhaust pipe 6 was formed in communication with the upper side of the hot water level control tank 5 downward.

In addition, a plurality of stone pieces 1a are formed in the upper part of the inner surface of the boiler body 1 to improve the heat conduction efficiency of the heat of combustion. In the drawing, reference numeral 7 denotes a hot water circulation pipe, and 8 denotes a valve valve.

The present invention connects the hot water circulation pipe 7 from the drain pipe 2 to the water supply pipe 3, and installs the water supply tank 4 on the top of the water supply pipe 3 so as to be positioned above the boiler body 1, and the water supply tank 4. Since a separate hot water level control tank (3) was installed inside and communicated with the exhaust pipe (2) delivered into the water supply tank (4), the hot water discharged from the boiler body (1) is circulated to the hot water circulation pipe (7) and at the same time the hot water level It is also supplied into the control tank 3, when the pressure of the hot water is strong, the water level in the hot water level control tank 3 rises to the position of FIG. 2b, and when the pressure of the hot water is weakened, it is lowered to the c position, Boost hot water circulation by pushing hot water. And the air in the hot water is exhausted to the steam exhaust pipe (6) while being exhausted toward the hot water level control tank receiving less resistance than the hot water circulation pipe side.

Therefore, the present invention is a hot water circulating in the hot water circulation pipe 7 is added to the low temperature of the low pressure water, the steam or air is exhausted to the steam exhaust pipe (6), so even if there is a slight bend in the hot water pipe, As a result, steam or air is blocked at the bent portion of the hot water pipe 7 so that the hot water circulation is not hindered. Thus, the hot water circulation is smooth and the steam contained in the hot water is exhausted to the steam exhaust pipe 6 so that the conventional water tank (4 There is no noise (squealing sound) as when it is exhausted from the inside of water), and since water droplets generated by the rot of steam are absorbed by the water in the water supply tank 4, there is almost no loss of water supply, and hot water piping construction There is no effect on the construction to keep the time level.

Claims (1)

In the well-known thing which installed the drainage pipe 2 and the water supply pipe 3 in one side of the boiler body 1, and installed the water supply container 4 in the upper end, the hot water level control tank 5 is built in the water supply container 4. The hot water circulation promoting device of the hot water boiler by communicating with the drain pipe (2) by forming an air exhaust pipe (6) downwardly in communication with the upper both sides of the hot water level control tank (5).
