Description

Sprinkler Mounting Apparatus for Doc Installation

The present invention relates to a sprinkler for fire fighting, and more particularly, to a sprinkler mounting device for installing a sprinkler installed in the duct more quickly to improve the sprinkler mounting structure to suppress the fire. .

In general, sprinkler equipment is used to extinguish a fire by using fire water in case of fire, and it automatically detects and extinguish a fire at the same time, and has an alarm function. Mandatory installation in large, crowded buildings.

As the building becomes taller and larger in size, even if a fire truck is dispatched quickly when a fire breaks out in the building, even if a fire truck is used to extinguish the fire by using an elevated ladder truck, it is not only limited to the upward movement of the ladder truck but also deep inside the building. There have been many difficulties in extinguishing old flames.

Accordingly, as the new fire suppression mechanism is gradually put into practical use and popularization, sprinklers capable of extinguishing fire are mandatoryly installed on the ceiling of each floor because water is sprayed by spraying high pressure water from the ceiling of each floor of the apartment.

In addition, due to the high rise of the building, the internal structure is complicated, and the window is designed to prevent the inflow of smoke and dust. The development of the communication industry has complicated electric and communication wiring inside the building. This installation involved a lot of difficulties in ventilating the indoor air and arranging the wiring.

In addition, fume ducts (Duct) is installed for the purpose of exhaust in the field process line, such as semiconductor factories, harmful gas flows inside the duct.

Accordingly, the installation of the sprinkler is also essential to the duct because a fire may occur due to the flammable and hot toxic gas in the duct.

Conventionally, using a flexible joint that is bent freely to a connection pipe connected to a water supply pipe to install a sprinkler on the duct, the reduxia coupled to the flexible joint is fixed to a mounting block, and the mounting block The silver is configured to securely fasten to a fixed base adhesively fixed to the duct.

In addition, in order to prevent leakage of harmful gas between the mounting block and the fixed base, a wide plate-shaped rubber sealer was inserted therebetween to seal it.

However, the conventional doc sprinkler having such a structure has a rubber sealer interposed between the mounting block and the fixed base to form a thin plate, and thus corrosion occurs as time passes. It is weakened and, accordingly, when a fire occurs in the duct, there is a problem that does not effectively block the phenomenon that harmful gas flows into the room.

In addition, there is a problem that the tube protecting the sprinkler head, which is inserted into the reducer insertion hole formed in the conventional fixed base, is separated by the wind speed of the harmful gas flowing in the duct, causing corrosion of the sprinkler.

The present invention has been made to solve such a conventional problem, to improve the structure to secure the fixed base to the duct and at the same time to integrate the redundancy and the fixed base to simplify the number of parts The purpose is.

Another object of the present invention is to minimize the number of O-rings used to maintain the air tightness of the assembly portion according to the assembly of the sprinkler due to the simplification of the number of parts to ensure the airtight maintenance between them.

According to a form of the present invention for achieving the above object, two bolts are inserted, the reddish insertion hole and the stepped jaw is formed in the center and the fixed base formed with an O-ring insertion groove in the upper surface, the redusian insert formed in the fixed base Redux is inserted into the ball and exposed to the lower part of the fixed base integrally formed, the O-ring insertion groove is formed in the center portion and the mounting block formed with a bolt insertion hole on the upper side, and the nut for fastening them in a state in which the mounting block is coupled to the fixed base A flange is mounted on the sprinkler head fixed to the lower part of the reducer, the first and second O-rings inserted into the O-ring insertion grooves formed in the fixed base and the reducer to maintain airtightness, and a stepped portion formed on the fixed base. Sprinkler for duct installation, characterized in that consisting of a vinyl cap fixed to the flange by The mounting apparatus is provided.

Hereinafter, with reference to Figures 1 to 4 showing the present invention as an embodiment in more detail as follows.

1 is an exploded longitudinal cross-sectional view of the present invention, FIG. 2 is a longitudinal cross-sectional view of the coupled state of FIG. 1, and FIG. 3 is a plan view of FIG. 2, wherein two bolts 2 are inserted into the fixed base 1. In the center, the redusche insertion hole 3 and the step 4 are formed, and the upper surface of the O-ring insertion groove 5 is formed roundly along the redusan insertion hole 3.

In addition, the mounting block 6 coupled to the fixed base 1 is integrally formed with a reducer 7 inserted into the red insertion hole 3 and exposed to the lower portion of the fixed base 1. O-ring insertion groove (8) is formed and the bolt insertion hole (9) is formed on the upper side.

The first and second O-rings 10 and 11 are respectively inserted into the O-ring insertion grooves 5 and 8 formed in the fixed base 1 and the reducer 7 to maintain their connection surface airtightness. The flange 12a of the vinyl cap 12 is mounted on the stepped portion 4 formed on the base to be supported by the reduser 7, and the sprinkler head 13 is coupled to the lower portion of the reduser 7.

In addition, the bolt insertion hole 9 formed in the mounting block 6 is inserted into the bolt 2 inserted into the fixed base 1, respectively, and the fixed base 1 and the mounting block 6 are engaged with the bolt 2. The nut 14 is screwed together to integrate them.

Referring to the operation of the present invention configured as described above are as follows.

First, the two bolts 2 are inserted at the time of injection of the fixing base 1, and at the same time, the fixing base is fixed to the duct (not shown) with adhesive bonds, and then the O-ring insertion groove formed on the upper surface of the fixing base 1. The first O-ring 10 is inserted into (5).

Thereafter, the sprinkler head 13 is screwed to the reducer 7 formed integrally with the mounting block 6, and at the same time, the second O-ring 11 is formed in the O-ring inserting groove 8 formed on the outer circumferential surface of the reducer 7. ) And the flange 12a of the vinyl cap 12 as shown in FIG. 4 is placed in the step 4 formed on the fixing base 1, and then the reduxing 7 of the mounting block 6 is fixed to the fixing base (4). When the redusche insertion hole 3 formed in the center of 1) is inserted, the flange 12a of the vinyl cap 12 is pressed and connected to the reduser 7.

As described above, when the mounting block 6 is assembled to the fixed base 1, their connection surfaces are kept airtight by the first and second O-rings 10 and 11.

After the mounting block 6 is assembled to the fixing base 1, the washer 15 and the nut 14 are sequentially inserted into the bolt 2 exposed by the bolt insertion hole 9 formed in the mounting block 6. When the nut 14 is screwed together, the washer 15 is pressed by the fastening force of the nut 14, so that the nut 14 is firmly fastened, so that the mounting block 6 is removed from the fixing base 1 even if vibration and impact are applied to the duct. The vinyl cap 12 will not be separated so that it is not separated.

As described above, the present invention is integrated with the redness and mounting block, so the number of parts is greatly simplified, so that the sprinkler can be quickly installed in the duct, as well as the parts management becomes easier by simplifying the number of parts.

In addition, due to the simplification of the number of parts, even if a small amount of O-rings are used on the connection surface according to the assembly of parts, airtightness can be maintained more completely, thereby preventing the harmful gas in the duct from entering the room. .
