Description

[0001] The present invention relates to a device for mounting an exhaust pipe of a boiler,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust port for exhausting waste gas generated when a boiler is operated. More specifically, the exhaust port is improved in structure so that a part of waste gas discharged through an exhaust port flows through a gap So that it is not leaked to the boiler.

Generally, a boiler is installed for heating and hot water supply. It uses heat generated by burning various fuels to warm water, use heated water directly, or use it to heat a home or various buildings.

Such boilers have been developed and used in various forms, from small boilers used for household use to large boilers used for industrial purposes, depending on their sizes.

Since the above-described boiler burns fossil fuels such as coal, oil, and gas, waste gas harmful to the human body such as carbon monoxide is generated. Therefore, in order to prevent gas poisoning accidents, An exhaust pipe is installed, and a waste gas is discharged to the exhaust pipe by connecting the exhaust gas to the outside.

1 is a vertical sectional view showing a state in which a conventional exhaust pipe is installed in a case. The exhaust pipe 2 is inserted into a through hole 3 formed in a case 1 and is fitted into a flange 2a Is fixed to the structure 4 located inside the case 1.

Therefore, the waste gas generated in accordance with the operation of the boiler is discharged to the outside through a flue (not shown) connected to the exhaust pipe 2 via the exhaust pipe 2.

(Patent Document 0002) Korean Patent Laid-Open Publication No. 10-2008-0059968 (Published on July 1, 2008)

However, the conventional apparatus having such a structure causes various problems as follows.

First, since the exhaust pipe is installed by simply inserting the exhaust pipe into the through hole formed in the case, there is a risk of a safety accident if a part of the waste gas leaks into the room through the gap between the exhaust pipe and the case.

Second, as moisture from the outside flows into the interior of the boiler through the gap between the exhaust pipe and the case, the metal parts are corroded.

It is an object of the present invention to improve the structure of the exhaust pipe and to develop a separate exhaust port so that the waste gas discharged through the flue is leaked through the installation portion of the exhaust pipe And to prevent such a problem.

Another object of the present invention is to provide a waste gas check hole in an exhaust port to check the waste gas exhausted from the waste gas check hole at any time, thereby maintaining an optimum operating state.

According to an aspect of the present invention for achieving the above object, there is provided an exhaust port to which a flange is connected to a case, an annular insertion space in which an exhaust pipe is received is formed between the projections, A first packing insertion groove is formed in the first packing insertion groove and a first packing is provided in the first packing insertion groove so as to maintain the airtightness with the case. The exhaust pipe, which is fixed to the structure and accommodated in the insertion space of the exhaust port, And a second packing is installed in the second packing insertion groove so that the second packing is closely connected to the outer peripheral surface of the projection.

The present invention has the following advantages over the conventional apparatuses.

First, since a separate exhaust port is fixed to the exhaust pipe, the gap is completely sealed by the first and second packings to maintain the airtightness, thereby preventing the waste gas discharged through the exhaust pipe from leaking into the room .

Secondly, external moisture is prevented from flowing into the interior of the boiler through the gap between the exhaust pipe and the case.

Third, since the second packing has a wing portion, the exhaust port is easy to insert, while the exhaust port coupled to the exhaust pipe is not removed due to the deformation of the wing portion.

Fourth, since a waste gas check hole is formed in the exhaust port, it is possible to check the waste gas discharged easily, so that the boiler can be always operated in the best condition.

Fifth, since the exhaust pipe is formed with a bulging portion at the lower end thereof, the sectional area of the exhaust port is prevented from being reduced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

FIG. 2 is a perspective view showing the construction of the present invention. FIG. 3 is a vertical sectional view showing a main part of the present invention. FIG. 4 is a longitudinal sectional view showing a second packing according to the present invention, A shorter exhaust pipe 12 is fixed and an annular insertion space 15 formed in the exhaust port 13 is fitted in the exhaust pipe 12. The outer flange 13a of the exhaust port 13 is provided with a first packing An insertion hole 18 in which an insertion groove 17 is formed and an upper end of which is connected to the upper end of the case 11 is inserted into the first packing insertion groove 17, And a first packing 16 that keeps airtightness with the first packing 16 is held.

A second packing insertion groove 19 is formed in the inner circumferential surface of the exhaust pipe 12 and a second packing 21 is formed in the second packing insertion groove 19 so as to maintain airtightness on the outer circumferential surface of the projection 20. Is installed.

4 is formed integrally with the second packing 21 so that the blade piece 21a is deformed in the insertion direction of the discharge port 13 when the discharge port 13 is inserted. The exhaust port 13 assembled with the exhaust pipe 12 is not easily detached without fixing means.

A waste gas check hole 22 for checking the waste gas is formed on one side of the exhaust port 13 so that the waste gas check hole 22 is normally closed by the stopper 23.

An exhaust pipe 12 is provided at its lower portion with an expansion portion 24 and a funnel-shaped second expansion portion 25 is formed at an upper portion of the exhaust pipe 12.

A stopper 26 for limiting the insertion depth of the flue is formed in the exhaust port 13.

Hereinafter, the operation of the present invention will be described.

First, a first packing 16 is inserted into a first packing insertion groove 17 formed in an exhaust port 13 and a second packing insertion groove 19 formed in an exhaust pipe 12 is inserted into a first When the protruding portion 20 of the exhaust port 13 is assembled to the exhaust pipe 12 with the second packing 21 having the exhaust pipe 21a inserted therebetween, So that it can be easily assembled.

When the exhaust port 13 is assembled to the exhaust pipe 12 as described above, the blade piece 21a of the second packing 21 is deformed in the inserting direction of the exhaust port 13 by the lower end of the protrusion 20, It is possible to prevent the exhaust port (13) from escaping from the exhaust pipe (12).

The second packing 21 is tightly connected to the protruding portion 20 of the exhaust port 13 to maintain the airtightness and at the same time the first packing 21 is formed on the flange 13a, The first packing 16 fitted in the groove 17 is in close contact with the case 11 so that the waste gas can be prevented from leaking to the outside in the course of discharging the exhaust gas through the exhaust pipe 12 and the exhaust port 13. [

When the exhaust pipe 12 is positioned in the insertion space 15 formed in the exhaust port 13 by assembling the exhaust port 13 to the exhaust pipe 12 as described above, (24) is formed to prevent a reduction in the sectional area of the exhaust port (12).

In the case of checking the state of the waste gas, that is, the combustion state of the boiler in the process of operating the boiler, it is necessary to remove the plug 23 that has closed the waste gas check hole 22, The state can be maintained in an optimal state.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied with various changes and modifications without departing from the scope of the invention. will be.
