Description

Fire sprinkler thermal member {SPRINKLER HEAD SENSE STUFF FOR FIRE FIGHTING}

The present invention relates to a fire sprinkler head for injecting extinguishing fluid in the event of a fire. More specifically, a sprinkler head for fire fighting to prevent the malfunction of the heat-sensitive member melted in heat so that the extinguishing fluid can be discharged in the event of a fire. It relates to a thermal member.

In general, sprinkler heads are installed on ceilings in buildings to detect fires and automatically spray extinguishing fluids.

These sprinkler heads are used in various ways depending on the method of use and installation method, the sprinkler head currently used generally is formed in the outlet 10 and the lower portion of the outlet 10 is screwed into the pipe as shown in FIG. A plurality of frames 20 and the head body 50 is formed integrally with the deflector 30 is formed on the lower end of the frame 20 to spray the digestive fluid in all directions, and the fixing bolt 31 to the head body 50 It consists of a heat-sensitive member 40 to open the outlet 10 in the event of a fire is fastened.

The sprinkler head configured as described above is extinguished with high pressure through the outlet 10 connected to the pipe when the heat sensing member 40 detects the fire, and the discharged extinguishing liquid is injected into the fire site by hitting the deflector 30. Extinguish a fire

In such a sprinkler head, the conventional thermal member 40 is installed between the discharge port 10 and the deflector 30 to detect when a fire occurs, the discharge stopper 41 is installed below the discharge port 10 to block the extinguishing liquid and The fastening bolt 31 is fastened between the discharge stopper 41 and the deflector 30, and consists of a glass bulb 45 for detecting a fire.

Therefore, when heat is applied at a predetermined temperature or more during a fire, the glass bulb 45 containing a substance such as alcohol or ether, which expands in volume, is ruptured, and the discharge stopper 41 supported by the glass bulb 45 is opened. The extinguishing fluid filled in the pipe is discharged.

However, the conventional sprinkler thermal member 40 operating as described above has a problem in that the glass bulb 45 made of glass material ruptures easily according to the vibration and surrounding conditions of the building, causing malfunctions, and built in the glass bulb 45. There is a problem that the production cost increases at the same time because the material such as alcohol or ether is expensive to cause environmental pollution.

The purpose of the present invention is to solve the conventional problems as described above, the fire sprinkler head heat-sensitive member to prevent the malfunction of the heat-sensitive member melted in the heat so that the extinguishing liquid is discharged in the event of a fire to make the operation of the sprinkler head accurately To provide.

In order to achieve the above object, the present invention seats a support shaft having an installation space on an upper deflector, embeds a thermal element that is melted by detecting a fire occurrence in an installation space, and is inserted into an installation space so as to be positioned on an upper portion of the thermal element. It is to install a fluid supporting the discharge plug to seal.

Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings in detail as follows.

The present invention is formed in the lower end of the frame 20 and the plurality of frames 20 formed in the lower portion of the outlet 10 and the outlet 10 is screwed to the pipe as shown in Figures 2 to 4 A head body 50 having an integral deflector 30 for injecting extinguishing fluid in all directions; In the sprinkler head for fire fighting is composed of a heat-sensitive member 40 is fastened to the head body 50 by a fixing bolt 31 to open the discharge port 10 in the event of a fire; The heat sensing member 40 includes a support shaft 44 seated on an upper portion of the spray plate 30 and provided with an installation space 44a having an open top and a fixing groove 44b fitted to the fixing bolt 31; A heat sensing member 43 embedded in the installation space 44a and melting to heat when a fire occurs; Inserted into the installation space (44a) so as to be located on the upper portion of the thermal member 43, the pressing projection (42a) is projected on the upper portion, the receiving groove (42b) is formed so that the lower portion is filled with the heat-sensitive body (43) A fluid 42; It is provided with a discharge stopper 41 for sealing the outlet 10 by having a recess (41a) is supported on the pressure projection (42a) of the flower (42).

The support shaft 44 preferably uses brass (Bress) having excellent thermal conductivity in order to transfer heat so that the heat-sensitive body 43 can be melted in a fast time during a fire.

The support shaft 44 has a cylindrical shape and a fixing groove 44b is formed at the bottom thereof to be supported by the fixing bolt 31, and an installation space 44a having an open top is formed as shown in FIG. The heat sensing body 43 and the fluid 42 are fitted, and the heat sensing body 43 and the fluid 42 may be protected from external shock.

The thermal element 43 is embedded in the support shaft 44 installation space 44a, and may be bismuth, lead, tin, cadmium (Bismuth), which may be rapidly melted by heat conduction in the event of a fire. It is preferable to use Wood's Metal made of an alloy of Cadmium).

The fluid 42, the discharge plug 41 is preferably made of stainless steel having a low thermal conductivity in consideration of the deformation caused by the fire.

The flower 42 has a pressing protrusion 42a for supporting the discharge stopper 41 protruding from the upper portion, is seated on the upper portion of the heat sensing member 43 is fitted into the installation space (44a) to flow from the external impact Can be prevented.

The accommodating groove 42b is to be filled with the heat-sensitive body 43 that is melted in the heat in the event of a fire, is formed in the vertical length in the center of the lower portion of the fluid 42.

The discharge stopper 41 is installed at the lower end of the connector 10 to seal the outlet 11, and has a disc shape having a predetermined thickness, and a recess 41a is formed at the center of the bottom to pressurize the fluid 42. It is firmly supported by the projection 42a.

On the other hand, Figure 4a and 4b shows another embodiment of the present invention, the spiral groove 42c is formed on the outer periphery of the fluid 42 is filled with the heat shield 43 is firmly fixed to the discharge plug 41 It can support and prevent malfunctions according to external shock and ambient temperature.

The present invention constituted as described above is inserted into the installation space (44a) so that the fluid 42 is placed on the upper portion of the mounting body (43) in the installation space (44a) of the support shaft 44, discharge plug 41 ) Is inserted into the discharge plug 41 groove 41a in the state in which the coupling member 10 is coupled to the connector 10, and is fixed at the bottom of the deflector 30 so that the support shaft 44 does not flow. Secure with bolts (31).

At this time, the fixing bolt 31 for fixing the support shaft 44 in the lower deflector 30, the female screw 30a is formed in the deflector 30 to be penetrated can be firmly fixed.

Therefore, when the fire occurs, the heat sensing body 43 is melted, the fluid 42 which is seated on the heat sensing body 43 and supports the discharge plug 41 falls to the bottom, and seals the outlet 11a. The discharge stopper 41 is separated and the extinguishing liquid is injected.

At this time, the molten thermal member 43 is filled in the receiving groove (42b) formed in the lower portion of the fluid 42, the fluid 42 may fall down.

The above descriptions are merely illustrative of one embodiment, and the present invention is not limited to the above-described embodiments, and can be variously modified within the scope of the appended claims.

For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

As described above, the present invention can prevent the malfunction of the heat-sensitive member melted in the heat so that the extinguishing liquid can be discharged in the event of a fire, thereby making it possible to accurately operate the sprinkler head and to reduce the manufacturing cost by simplifying the construction of environmentally friendly materials. It is a very useful design to do.
