Description

Automatic fire extinguisher with double valve {AUTOMATIC FIRE EXTINGUISHER}

The present invention relates to an automatic fire extinguisher having a double valve, and more particularly, to the provision of an automatic fire extinguisher having a double valve configured to prevent the leakage of the extinguishing fluid due to airtightness deterioration not in a fire.

Automatic fire extinguishers are mandatory in fire-fighting areas such as kitchens in multi-family houses such as apartments and kitchens in general restaurants, so that they can be quickly suppressed in the event of a fire to reduce property and casualties.

Pressurized type to extinguish the extinguishing liquid by using the pressure generated by operating the detonation cartridge as described above, and the gas is injected into the container together with the extinguishing liquid to be blocked by the valve, and then filled in by opening the valve. It is divided into the accumulator type to extinguish the extinguishing fluid by the gas pressure.

As shown in FIG. 5, the accumulator-type automatic fire extinguisher 1 to which the prior art is applied is provided with an airtight member in the connector 5 provided to protrude into the container 4 filled with the extinguishing liquid 2 and the compressed gas 3. Screw the valve body (6) through.

Inside the valve body 6, a discharge tube 7 for discharging the extinguishing liquid is connected to a discharge hole 8 formed on the outer surface of the valve body 6, and the discharge tube 7 and the discharge hole 8 In order to prevent leakage of the extinguishing liquid and the compressed gas through the valve 10 in between.

The valve 10 is integrally formed at the lower end of the valve stem 12 and the valve stem 12 connected to the normal operating means 11 interlocking with the fire detector protruding upward from the valve body 6 and discharged. It consists of a valve head 13 which cuts off between the pipe 7 and the discharge hole 8, and always the valve head between the lower part of the valve head 13 and the discharge pipe 7 via a valve spring 14. Allow (13) to remain blocked.

The valve body 6 on both sides of the discharge hole 8 is combined with a pressure gauge 15 for checking the pressure inside the container 4 and an alarm for detecting a leak state, and on both sides of the valve head 13. The pressure gauge 15 and the alarm are configured in communication with the sensing passage 17 for detecting the pressure and the leak state.

In the prior art as described above, when a fire occurs, the fire extinguishing liquid may be discharged by pressing the valve stem exposed to the valve body to separate the valve head blocking the discharge pipe and the discharge hole. Fire extinguishing fluid is injected into the fire position through the nozzle through the discharge hole by the force pushed by the compressed gas filled in the inside by securing the space to extinguish the fire.

Fire extinguishing fluid filled inside the accumulator-type automatic fire extinguisher is strongly corrosive, so in the case of prolonged passage of time, airtight materials such as O-rings intervene to prevent leakage, and the connection part of each screwed part. The digestive fluid leaks out between the micro cracks that occur in the car.

As described above, since the high pressure compressed gas filled for aging of the airtight material and the connection part and the high pressure compressed gas filled for the discharge of the digestive fluid inside the container continuously generates the force to extinguish the digestive fluid, it is not a large amount. Leaks occur.

In particular, because the minute amount leaks continuously for a long time, the pressure gauge or alarm is not enough to detect enough, so the pressure drop on the gauge is not released or the alarm does not occur. Since it is installed in an unexposed space, the user cannot easily visually check the leak state.

As such, a phenomenon in which a small leaking digestive fluid falls into a heating device in a condensed state occurs. In this case, it causes contamination of kitchen utensils and the like. It will be obvious to adversely affect, and when the cookware is in use, a big problem occurs that causes fire by the extinguishing liquid for extinguishing the fire.

This is because the valve, which causes various problems due to the leaking of the digestive fluid, is composed of a single body, and thus does not have a function of quickly blocking a leak occurring at any one place.

In the present invention, the valve body is coupled to the connector provided in the container filled with the extinguishing fluid and the compressed gas as invented to solve the above problems, and is formed on the valve body outer surface to discharge the extinguishing fluid inside the valve body An accumulator-type automatic fire extinguisher having a discharge pipe connected to the discharge hole and a valve for preventing the extinguishing liquid from leaking to the outside between the discharge pipe and the discharge hole.

The valve is provided between one valve provided between the valve body and one discharge pipe coupled through an airtight member, and two valves interlocked with one valve provided between the first discharge pipe and two discharge pipes coupled through an airtight member. It is designed to prevent contamination of fire extinguishers and to prevent contamination of fire extinguishers while improving the quality of fire extinguishers by preventing the leakage of extinguishing fluids in a double configuration.

The present invention consists of a valve interposed between the valve body mounted on the fire extinguisher and the discharge pipe in two to block the leakage of the fire extinguishing fluid to increase the quality of the fire extinguisher while preventing the underlying problems of pollution and fire caused by fire extinguishing fluid leakage It is an invention having a variety of effects, such as to provide convenience to users by solving.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

1 is an exploded perspective view showing an automatic fire extinguisher having a double valve to which the technique of the present invention is applied, FIG. 2 is a cross-sectional view illustrating an automatic fire extinguisher having a double valve to which the technique of the present invention is applied, and FIG. 4 is a schematic diagram showing another example of an automatic fire extinguisher having a double valve to which the technique of the present invention is applied.

A general accumulator type automatic fire extinguisher 100 is coupled to the valve body 105 to the connector 104 provided in the container 103 filled with the extinguishing fluid 101 and the compressed gas 102, the valve body 105 inside The discharge pipe 106 for discharging the extinguishing liquid is connected to the discharge hole 107 formed on the outer surface of the valve body 105, and the digestive fluid leaks to the outside between the discharge tube 106 and the discharge hole 107 It is configured with a valve 110 for preventing it.

In the present invention, by improving the valve 110 to prevent the leakage of the extinguishing fluid to the double to prevent the leakage of the source at the source to be characterized in that it can be excluded from the contamination phenomenon and the risk of fire caused by the extinguishing fluid.

The valve 110 is a valve 115 provided between the valve body 105 and the one discharge pipe 112 is screwed through the airtight material 111, the one discharge pipe 112 and the airtight material ( 113 is provided between the two discharge pipes 114 are screwed through the two valves 125 that are interlocked with one valve 115 is configured.

The one valve 115 protrudes upward from the valve body 105 and is integrally formed with one valve stem 117 and one lower end of the one valve stem 117 which are connected to a general operation means 116 interlocking with a fire detector. It is formed of one valve head 118 to block between the one discharge pipe 112 and the discharge hole (107).

Between the lower side of the one valve head 118 and the settlement 119 formed in the one discharge pipe 112 through the one valve spring 120 is configured to always maintain the one valve head 118 in the blocking state do.

The two valve 125 is inserted into the two valve hole 126 formed at the center of the one discharge pipe 112 to be integrated into the two valve stem 127 and the lower end of the two valve stem 127 to maintain a stable state 2 to block the lower end of the discharge pipe 112 so as to prevent the leakage of the extinguishing fluid through a plurality of discharge holes 128 for discharging the extinguishing fluid for fire suppression by forming the outer side of the two valve hole 126. The valve head 129 is configured.

Between the lower side of the two valve head 129 and the settling 130 is formed in the two discharge pipe 114 via the two valve spring 131 is configured such that the two valve 125 is always in a blocked state.

The lower end of the one-valve header 118 constituting the one-valve 115 is further provided integrally with an operation pin 133 that can be connected to the upper surface of the two-valve stem 127 constituting the two-valve 125. In the event of a fire, it is possible to interlock by the usual operating means 116 mounted on the valve body 105.

As another technique for maintaining the first and second valves 115 and 125, the first and second valve springs 120 and 131 may be pulled without pushing the first and second valves 115 and 125 through the first and second valve stems 117 and 127. It may be configured.

Of course, the valve body 105 on both sides of the discharge hole 107 is combined with a pressure gauge 135 for checking the pressure inside the container 103 and an alarm 136 for detecting an alarm by detecting a leak state. The pressure gauge 135 and the alarm 136 on both sides of the head 118 will be configured to communicate with the sensing passage 137 for detecting the pressure and the leak state.

Looking at the operation state of the automatic fire extinguisher 100 having a double valve to which the technology of the present invention as described above is as follows.

When a fire occurs in the above state, a fire is detected by a fire detector, and the single valve stem constituting the one valve 115 by the normal operating means 116 mounted on the valve body 105. By pressing 117, the one valve spring 120 overcomes the pushing force, and the one valve head 118 opens the blocked state of the one discharge pipe 112 and the discharge hole 107.

At the same time, since the operation pin 133 integrally formed under the one valve head 118 is in contact with the upper surface of the two valve stem 127 constituting the two valve 125, the two valve 125 is also naturally pressed. The state which blocks the lower end part of the 1 discharge pipe 112 is canceled | released.

Then, the extinguishing fluid 101 contained in the container 103 is transferred to the valve body 105 through the discharge hole 128 of the second discharge pipe 114 and the first discharge pipe 112 by the force pushed by the compressed gas 102. It is injected to the fire position through the nozzle via the discharge hole 107 formed to extinguish the fire.

In addition, when a fire does not normally occur, it is possible to prevent a phenomenon in which the extinguishing fluid 101 or the compressed gas 102 filled in the container 103 is leaked to the outside by a double valve 110. Looking in detail as follows.

For example, when a leak occurs in the one valve 115, only the compressed gas or the extinguishing liquid located in the one valve 115 is leaked and then shut off by the two valves 125, thereby ensuring safety, and the two valves ( If leakage occurs in the 125) will be cut off from the one valve 115 will also ensure safety.

That is, when there is an abnormality in the one valve 115, the two valve 125 blocks the extinguishing fluid 101 and the compressed gas 102 in the container 103 from moving to the one valve 115. The two-discharge head 129 integrally formed at the lower end of the two-valve stem 127 accommodated in the two-valve hole 126 formed at the center of the one-discharge pipe 112 finished with the discharge pipe 114 is one discharge pipe ( The lower end of 112 is cut off.

Therefore, when the compressed gas 102 is injected after the valve 110 is mounted on the fire extinguisher 100, only the compressed gas 102 remaining in the space in the valve 115 is discharged to the outside and then the extinguishing liquid in the container 103 is discharged. This is possible because the movement of the 101 and the compressed gas 102 in the direction of the one valve 115 through the discharge hole 128 of the one discharge pipe 112 is blocked.

In addition, when an abnormality occurs in the two-valve 125, the extinguishing fluid 101 and the compressed gas 102 in the container 103 flow into the minute gap between the two-valve head 129 and then the two-valve hole 126 and It moves in the direction of one valve 115 through the discharge hole (128).

Then, since the one valve 115 is in a state where there is no abnormality, the one valve head 118 blocks the outflow through the discharge hole 107 to the outside.

In addition, when leakage occurs in the container 103 instead of the valve 110, since the shading is performed in the direction from the one valve 115 to the two valve 125, the pressure gauge 135 mounted on the valve body 105 or Since the abnormal state is recognized through the alarm 136, it is possible to quickly check and secure a safe state.

The present invention has the advantage that it is possible to prevent the contamination and fire of the fire extinguisher installation location while improving the quality of the fire extinguisher by preventing the phenomenon that the fire extinguishing fluid leaks by constituting the double coupled valve to the container constituting the fire extinguisher. .
