Description

Flush Type Sprinkler Head {Flush Type Sprinkler Head}

The present invention relates to a sprinkler head, and more particularly, to a flush type sprinkler head that is installed so as to be exposed to the ceiling of the building to spray firefighters to quickly extinguish the fire early in the event of a fire.

In general, sprinkler equipment is used to extinguish the fire by using fire water in case of fire, and it automatically detects and extinguish the fire at the same time. It is mandatory for many people to be installed in large, crowded buildings.

The sprinkler system is roughly classified into a wet system, a dry system, and a deluge system according to a method of operation, and is classified into a standard response type and an early response type according to the response speed. do.

The sprinkler is designed to operate automatically when the temperature near the ceiling rises above a certain temperature due to the fire, but the sprinkler head, the attachment position, and the waterproofing amount depend on the type of building and the degree of interior. It is prescribed by fire law.

1 and 2 are longitudinal cross-sectional views showing a conventional flush type sprinkler head, in which a water outlet (2a) is formed at the center of the body (2) screwed to the branch pipe (1), the normal state on the bottom of the body The deflector (4) for closing the outlet port in the air is installed while maintaining the airtight by the spring sheet (3). ) Is screwed in.

Frame 6 is screwed to the body 2, the inner peripheral surface of the through hole formed in the lower center of the frame 6 is shallower than the radius of the retaining ring (7) An accommodation space 8 with an inclined surface is formed.

Directly below the deflector 4 is provided with an inner loading plate 9 for applying a load to the retaining ring 7 whose flange is located in the receiving space 8 as the set screw 5 rotates. A portion of the retaining ring 7 is accommodated directly below the loading plate 9, and then the outer loading plate 10, which is separated from the frame 6 together with the retaining ring 7 in the event of a fire, is installed in sequence. have.

In addition, a heat collector 11 including a plurality of heat collectors 11 is installed under the outer loading plate 10 so as to quickly react to heat during a fire, and lead (Pb) is disposed inside the heat collectors located at the lowermost of the heat collectors. The fuse metal 12 which consists of the main component is provided, and the outer loading plate 10 and the heat collector 11 are integrated by the locking screw 13. As shown in FIG.

In the state in which the sprinkler head is assembled as shown in FIG. 1, the retaining ring 7 is located in the receiving space 8 of the frame 6 so that the inner loading plate 9 and the outer loading integrated by the locking screw 13 are provided. The plate 10 and the heat collector 11 are not separated from the frame 6, and the water outlet 2a is closed by the spring sheet 3, so that the fire water is not sprayed.

In this state, if the heat collector 11 receives heat and melts the fuse metal 12 in the process of causing a fire in the building to move heat along the ceiling surface due to convection, the outer loading plate 10 may fuse the fuse metal. The retaining ring 7 located between the inner loading plate 9 and the outer loading plate 10 is retracted by the restoring force because it is released from the inner loading plate 9 while descending by the height of. The outer loading plate 10 and the heat collector 11, which are located directly below the inner loading plate 9, are freely dropped as shown in FIG. 2 to be separated from the frame 6.

After the inner loading plate 9, the outer loading plate 10, the retaining ring 7 and the heat collector 11 are separated from the frame 6 as shown in FIG. 2, the outlet 2a of the body 2 is removed. The deflector 4, which has been pressed on the spring seat 3 positioned at the position, freely falls downward due to its own weight and is spread over the lower end of the frame 6, so that the high-pressure fire water is discharged through the water outlet 2a and the deflector 4 The firefighters are sprayed evenly in all directions through the injection space 4a formed in the deflector 4, thereby suppressing the fire.

However, this conventional sprinkler head has a number of problems as follows.

First, even if the fuse metal melts due to the fire and the inner loading plate, outer loading plate, retaining ring, and heat collector are separated from the frame, the deflector that is closing the outlet of the body is so lightweight that it cannot be lowered from the body quickly. In addition, when descending inclined, the deflector is inclined to close some injection spaces, so that firefighters cannot be sprayed quickly.

Second, if the ceiling surface on which the sprinkler head is installed is inclined, the deflector cannot be vertically lowered and tilted to one side, so it is impossible to spray firefighters in all directions evenly through the spray space formed in the deflector. There was a fault.

Third, the neck of the body (the part where the deflector is connected) is long, and the heat collector is exposed to the outside of the frame for a long time, so that the sprinkler head is exposed to the outside when installed on the ceiling surface, which damages the appearance.

The present invention has been made to solve such a conventional problem, and the object of the present invention is to improve the structure to form a valve cap integrally with the deflector to prevent water spraying failure caused by the deflector in advance.

Another object of the present invention is to form a plurality of injection holes directly along the side wall of the frame to enable the spraying through the injection hole at the same time as the lowering of the valve cap.

Still another object of the present invention is to form an outer loading plate on a plate to minimize the height of the sprinkler head exposed from the ceiling surface.

According to an aspect of the present invention for achieving the above object, a plurality of injection holes are formed along the lower sidewall of the frame, and an accommodating space shallower than the radius of the retainer ring is formed in the lower part of the frame to cut one end into the accommodating space. The retainer ring is inserted and the inclined surface of the inner loading plate is connected to the upper portion of the retainer ring, and the inclined surface of the outer loading plate on the plate is connected to the lower portion thereof, so that the inner loading plate and the outer loading plate are fastened by the locking screw. A pressing type sprinkler head is provided, characterized in that the pressing force of the inner loading plate is configured to be controlled by an press screw screwed to the valve cap.

The present invention has several advantages as follows.

First, a plurality of injection holes are formed along the side wall of the frame, and the deflector is integrally formed with the valve cap, so that the fire water sprayed through the water outlet of the body can be quickly sprayed through the injection holes in case of a fire, so that the fire is quickly suppressed. This will be possible.

Second, when the inner loading plate is lowered by the operation of the impress screw, the angle of the inclined surface formed on the inner loading plate is set larger than the angle of the inclined surface formed on the outer loading plate, thereby minimizing by dispersing the pressure applied to the fuse metal.

Third, it is possible to minimize the height of the outer loading plate exposed to the lower side of the frame to make the appearance according to the installation of the sprinkler, it is possible to quickly sense the high heat flowing along the ceiling surface in the event of a fire.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 and 4 as an embodiment.

3 and 4 is a longitudinal sectional view showing a flush type sprinkler head of the present invention, the same parts as the conventional configuration of the configuration of the present invention will be omitted with the same reference numerals.

According to the present invention, a plurality of injection holes 16a are formed along a lower sidewall of the frame 16 which is screwed to the body 2, and an accommodating space shallower than the radius of the retainer ring 7 is formed below the frame 16. 18 is formed.

A retainer ring 7 having one end cut out is inserted into the receiving space 18 formed at the lower portion of the frame 16, and the inclined surface 17a of the inner loading plate 17 is disposed on the retainer ring 7. The locking screw 13 is fitted into the through hole formed in the outer loading plate 19 so that the inclined surface 19a of the outer loading plate 19 is connected to the lower portion of the retainer ring 7. As they are screwed to the plate 17, they are configured to be integrated.

The upper portion of the inner loading plate 17 is provided with a valve cap 20 for closing the water outlet 2a formed in the body 2 and the recess groove 2b formed at the end of the water outlet 2a of the body 2. There is a spring seat (3) is installed to quickly lower the valve cap 20 in the event of a fire, the lower portion of the valve cap 20 is screwed into the impress screw 15, the lower end of the inner loading plate (17) It is fitted in the mounting groove 17b formed in ().

At this time, the outer loading plate 19 is formed on a plate forming a substantially same plane with the bottom surface of the frame 16, the lower portion of the outer loading plate 19, the upper heat-sensitive plate 11a of the heat collector 11 It is configured to be connected by the insulating washer 14, which has the advantage that the sprinkler head can be minimized the height exposed from the ceiling surface.

On the other hand, the angle θ1 of the inclined surface 17a formed on the inner loading plate 17 is set larger than the angle θ2 of the inclined surface 19a formed on the outer loading plate 19 on the basis of the horizontal plane S. It is more preferable.

This is because the inner loading plate 17 and the outer loading plate 19 integrated by the locking screw 13 are assembled to the frame 16 so that the retainer ring 7 located on the inclined surfaces 17a and 19a is provided with a receiving space ( The retainer ring 7 is expanded by the inclined surface 17a formed in the inner loading plate 17 in the process of adjusting the press screw 15 screwed to the valve cap 20 in the state of being positioned inside the 18). While fitting to the interior of the receiving space 18 is to distribute the pressure acting on the fuse metal (12).

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

First, when the inner loading plate 17 and the outer loading plate 19 are coupled to the inside of the frame 16, the retainer ring 7 coupled to the inclined surfaces 17a and 19a thereof is placed at the bottom of the frame 16. It is located in the formed receiving space 18, when the locking screw 13 is pulled to pull the inner loading plate 17, the retainer ring 7 located on the inclined surface (17a) (19a) is the inner loading plate 17 Since it is accommodated inside the receiving space 18 while being expanded by the inclined surface (17a) of the they are not separated from the frame (16).

Thereafter, the valve cap 20 having the spring seat 3 coupled thereto is positioned inside the frame 16, and then the frame 16 is screwed to the body 2 so that the spring seat 3 has the valve cap ( Pressed by 20 to close the water outlet 2a formed in the body 2.

After assembling the frame 16 to the body 2 by the operation as described above, the pressure applied to the fuse metal 12 by adjusting the impress screw 15 through the hole 13a formed in the locking screw 13. By adjusting the, the installation work of the sprinkler head is completed.

In this state, when the heat collector 11 receives heat and melts the fuse metal 12 in the process of causing a fire in the building to move heat along the ceiling surface due to convection, the outer loading plate 19 may fuse. Since it is lowered by the height of the retainer ring (7) which is extended by the inclined surface (17a) (19a) formed in the inner loading plate 17 and the outer loading plate 19 is located inside the receiving space (18) While being compressed, it is released from the accommodation space 18 and the locked state is released. Accordingly, the inner loading plate 17 and the outer loading plate 19, the retainer ring 7 and the heat collector which are integrated by the locking screw 13 are thus released. 11 is separated from the frame 16 at the same time as shown in FIG.

As such, after the inner loading plate 17, the outer loading plate 19, the retaining ring 7, and the heat collector 11 are separated from the frame 16, the spring is located at the outlet 2a of the body 2. Since the valve cap 20 holding the seat 3 is lowered more quickly by the restoring force of the spring seat 3, and is applied to the lower end of the frame 16, the high-pressure fire water is discharged through the outlet 2a. Since it hits the top of the valve cap 20 and then evenly sprayed in all directions through the injection hole (16a) formed along the side wall of the frame 16 will be able to extinguish the fire quickly.
