The present invention having the above-described structure is applied to a case in which the water tube plate 10 having the structure as shown in FIG. 1 is mounted on a gas boiler.
Heating water supply and return pipeline)
As shown in FIG. 2, the main parts for operating the gas boiler are attached to each pipeline. That is, the water supply line 11
The water amount sensing control valve 20 is used for the fastener 16d, the hot water heat exchanger 21 is used for the fastener 16b of the hot water pipe 12, and the three-way valve is provided for the fastener 16c provided on the path of the heating water supply pipe 13. Tighten 23.

The circulating pump 22 is attached to the lower part of the gas boiler while the circulating pump 22 is fastened to the fastener 16a of the circulating pump connecting line 15.

On the other hand, the water tube plate 10 of the present invention desirably employs a synthetic resin material as its material in order to simplify production and have a firm binding force. In various forms, the metal member can be applied partially or entirely.

Further, as a manufacturing method, a method of manufacturing a mold in advance and injecting molten resin into the mold, manufacturing an upper plate and a lower plate separately and bonding them, or May be made by any of the manufacturing methods of binding via fastening means.

That is, as shown in FIG.
0 and 200 are manufactured separately, and these are bonded and used. As a bonding method, as shown in FIG. Board 100
And the lower plate 200 are each provided with a semi-cylindrical conduit, and one conduit is formed by coupling the upper and lower plates 100 and 200.
The groove 201 of the lower plate 200 and the upper plate 1
Since the fixing protrusions 101 of the upper plate 100 are fitted to the fixing protrusions 101 of the upper plate 100, the sealing members 202 inserted into the concave grooves 201 are deformed while the fixing protrusions 101 of the upper plate 100 are combined with each other. Will be possible. Subsequently, the water tube plate 10 is fastened and fastened by fastening means 300 penetrating a large number of holes provided at arbitrary positions.

Since the tightening position of the tightening means 300 is a position deviating from the position of the conduit on the water tube plate 10, it does not affect the flow of the supply water moving through the conduit. The water tube plate 10 is connected to the sealing member 202 to prevent foreign substances flowing from the outside from flowing into the pipeline, and effectively removes liquid substances that easily leak to the outside due to the pressure inside the pipeline. Can be shut off.

Further, another embodiment of the water pipe connection method is shown in FIG.
When heat of the melting point is applied to the bonding surface between the lower plate 200 and the lower plate 200, that is, the fusion surface 4 between the upper plate 100 and the lower plate 200.
When the upper plate 100 and the lower plate 200 are connected to each other, the fused surfaces 400 of the upper plate 100 and the lower plate 200 are fused, and pressure is applied from the outside. After a certain period of time, the fusion surface 400 solidifies, and as a result, one water tube sheet 10 is formed. This water tube plate 10
Since the upper plate 100 and the lower plate 200 are completely connected to each other, the structure is excellent in airtightness and does not require a separate fastening means.

As shown in FIG. 4C, the upper plate 100
Fusible member 401 between the contact surface of
When heat is applied from the outside, the fusion member 40
1 melts. At this time, when the upper plate 100 and the lower plate 200 are brought into close contact with each other and pressure is applied from the outside, the fusion member 401 fuses to the upper member 100 and the lower plate 200, and after a certain period of time, the fusion member 401 solidifies. Upper plate 100 and lower plate 2
A firm connection of 00 is made.

On the other hand, as shown in FIG. 5, the function of the present invention constituted by the above-mentioned connection is that direct water (tap water) is connected to the water supply conduit 11 and hot water is connected to the hot water conduit 12. A control valve for controlling discharge is connected, and heating pipes are provided in the heating water supply pipe line 13 and the heating return pipe line 14. In such a state, when water flows in through the water supply line 11 of the equipment main body connected to a water pipe (not shown) during the initial operation of the gas boiler as shown in FIG. By the operation of the valve 20, the water is supplied to the hot water heat exchanger 21 or the water tank 50. The water supplied to the water tank 50 passes through the circulation pump connecting line 15 and is pumped by the circulation pump 22, and the water is supplied to the main heat exchanger 3 in a state where the pressure is increased.
The heating pipe is supplied to the hot water heat exchanger 21 by the operation of the three-way valve 23 or provided in a fixed arrangement through the heating water supply pipe 13 in a state where heat is exchanged by the operation of the burner 40 and the operation of the burner 40. Circulated to 60. In addition, heating piping 60
After passing through the heating return line, the water undergoes a continuous circulation operation of being guided to the water tank. The hot water discharged from the hot water heat exchanger 21 is discharged to the outside by the hot water line 12. (However, since the gist of the present invention relates to a water tube plate, a fastening structure for components other than the above-mentioned main functional components is omitted).

On the other hand, the water tube plate 10 of the present invention can be manufactured by simplifying the manufacturing process because the water tube plate can be formed and manufactured by a simple process through a mold operation by eliminating a number of steps. It realizes the doubling of the work efficiency and the mass production system, and has the effect of reducing the manufacturing unit price. When this is applied to a gas boiler, the complicated piping structure is improved, and the water pipe plate 10 made of one plate is used. The simple piping structure avoids the complicated piping structure, which makes installation work easy and easy to attach and detach even in the case of failure repairs, as well as making it easy to replace essential components and clean up. Can also be achieved.

[0028]

As described above, according to the present invention, a water tube plate composed of a single plate is used regardless of an existing complicated piping structure.
Since the water supply line and the return line are provided integrally and can be applied to the gas boiler, the structure is simplified, and useful effects such as shortening of working time, saving of parts, and reduction of manufacturing unit price are achieved. It is something.
