A fire detection tube including a check valve coupled with a valve device, a fire detection tube coupled with the check valve and maintaining a constant pressure, and a check valve cap or pressure gauge coupled with a check valve connected to one side of the fire detection tube. The present invention relates to an attachment type automatic fire extinguishing device.

In more detail, the valve device is a pressure gauge for measuring the pressure and the pressure detection device is coupled to the valve body on both sides, respectively, and the upper side of the valve body coupled with the valve device O-ring for preventing leakage of the extinguishing agent It is formed and configured to be coupled to the check valve on one side of the valve body, to form a cylindrical tube through which the extinguishing agent can pass inside the body of the check valve, the check valve is coupled to the spring inside the check valve body A check valve o-ring which forms a needle and prevents leakage of pressure to maintain a constant pressure inside the fire detection tube on both sides of the combination of the spring and the needle, and includes a sleeve coupled with the fire detection tube; A fire detection tube-mounted automatic fire extinguishing device comprising a check valve formed by

Thermal open autonomous devices that open by sensing heat or pressure are thermally open autonomous devices with heat detection only, and thermal open autonomous devices with pressure and heat detection. There is an automatic device, and a glass-bulb type automatic device is provided for the thermally open device with pressure and heat sensing.

Thermal element means to block the device in normal condition, but when it reaches a certain temperature by heat transmitted from flame, it destroys or dissolves itself and escapes so that the device is opened and the extinguishing agent contained in the compressed state is automatically ejected. Fuzzy Blink refers to a part which is fused with a fusible metal or assembled by a fusible material, and glass beebrain refers to a glass bulb in which a liquid or the like is sealed in a glass sphere.

When the surface temperature of the fusible link or glass bulb reaches a specific temperature determined by the selected fusable material or the thermosensitive liquid, the fusible material melts away from the fusible link and in the case of the glass bulb, Fire extinguishing agent contained in compressed state is ejected by extinguishing bulb by breaking away bulb, but extinguishing fire. However, in case of fusible-link type and glass bulb type automatic device depending on the location of fire, heat-sensitive liquid It takes a considerable time for the heat to reach a constant temperature from the flame is difficult for the initial extinguishing of the fire, if the ignition site is far from the fire equipment there is a problem that the initial extinguishing is more difficult.

In addition, the composition is very complicated, so it is not easy to manufacture, assemble and dismantle, and it is expensive. There is a problem that cannot be used for.

In case of heat sensing tube using fire sensing tube, if extinguishing agent enters inside of fire sensing tube, extinguishing agent, which is mixture of hydrogen, carbon, fluorine, etc., reacts with fire sensing tube to corrode fire sensing tube and cause aging. As the life is shortened and the chemicals are stored in the fire detection tube, the fire detection tube also belongs to a storage container that requires the certification of the Korea Fire Protection Corporation. If the fire detection tube that meets the standard to replace the production cost of the product is a problem.

In addition, the fire detection tube should be kept at a constant temperature at all times and operated at a constant temperature. However, if the fire detection tube is filled with an extinguishing agent, if the extinguishing agent corresponds to a mixed chemical, the specific heat of the extinguishing agent is high, so Thermal energy is conducted to the fire extinguishing agent, so it does not react sensitively in case of fire, and the temperature is not constant because the specific heat varies according to the components, mixing ratio, and specific heat of each extinguishing agent. When is filled, the extinguishing agent is settled due to long time unused, the concentration difference between the portion with and without the drug in the fire detection tube has a problem that the detection temperature is not constant.

In the case of the existing automatic fire extinguishing device, when the handle (lever) installed on the top of the valve body is rotated from the upper side to the lower side to maintain the opening and locking state, the upper handle is easily operated by the handle operation by an external force of a general person or a child. The opening and closing of the moving passage of the extinguishing agent is controlled while rotating to the lower side, there is a problem that the automatic fire extinguishing device does not operate when a fire occurs because it is easily locked.

The present invention has been made in order to solve the problems of the prior art as described above, using a fire detection tube-attached automatic extinguishing device is difficult to extinguish fire or small spaces, corners or the like, fire detection device and fire suppression device The purpose of the present invention is to provide an automatic fire extinguishing tube attachment type fire extinguishing system capable of detecting fires and extinguishing fires in the early stages of fire.

Another object of the present invention is that it is difficult to extinguish the fire in the early stage of the fire because the operation time of the automatic diffusion fire extinguisher including the existing temperature sensor, smoke sensor and surveillance camera may be delayed in relation to the distance of the fire zone. In case of fire detection system, it takes a lot of time to detect this in the early stage of fire because it is detected on the ceiling or wall. It is difficult to extinguish fire by using fire detection tube, The purpose of the present invention is to provide a fire detection tube-attached automatic fire extinguishing device capable of detecting a fire occurrence and extinguishing the fire at the beginning of a fire by installing it where it is difficult to install a fire detection device and a fire suppression device.

Still another object of the present invention is that when there is no check valve, the fire detection tube is a mixture of a pressure-extinguishing agent and a pressurized gas such as nitrogen of a certain pressure and air is not a constant temperature detected in the fire detection tube, such as a fire extinguishing agent Due to the mixing, there is a problem of causing corrosion in the fire detection tube. By using the check valve, pressurized gas such as nitrogen in the fire detection tube maintains a constant pressure and detection temperature. The purpose of the present invention is to provide an automatic fire extinguishing tube attachment type automatic fire extinguishing device which is filled with nitrogen gas to prevent corrosion of the fire detecting tube.

In addition, if there is no check valve, the pressure and extinguishing agent flows into the fire detection tube, and there is a difficulty in attaching and detaching it. The purpose of the present invention is to provide an automatic fire extinguishing tube attachment type automatic fire extinguishing device that can be easily separated at any time between the fire extinguisher and the fire sensing tube.

Another object of the present invention is to reduce the pressure caused when the fire detection tube is melted due to the fire in order to recognize the fire occurrence to the user using the fire detection tube-attached automatic fire extinguishing device when the fire occurs Due to the ejection, the pressure detector transmits the pressure inside the cylinder to the controller as an electrical signal to be displayed on the fire alarm system. In the case of the siren and the indicator, the fire alarm is notified through the sound and the light of the indicator and wired / wireless communication. In the case of the interface, the purpose of the present invention is to provide an automatic fire extinguishing tube attachment type fire extinguishing device connected to an external terminal through a wired / wireless communication interface to notify a fire occurrence.

Another object of the present invention is the upper handle is easily handled by the external force of the public or children when the handle (lever) installed to maintain the open and locked state by rotating from the upper side to the lower side to the upper handle is easily The opening and closing of the moving passage of the extinguishing agent is controlled while rotating downward, and it is easily locked so that the fire sensing tube-attached automatic extinguishing device does not operate in the event of a fire. The nut can control the leakage of the push bolt and the extinguishing agent. It is an object of the present invention to provide a fire detection tube-attached automatic fire extinguishing device that can prevent such a malfunction by forming a valve device including a cap.

The above and other objects of the present invention are coupled to the cylinder (6) containing the extinguishing agent, and the pressure gauge (4) and the pressure detection device (5) for measuring the pressure respectively on both sides of the valve body (3) and the valve A valve configured to be coupled to the check valve 20 on one side of the valve body 3 to form a push bolt 10 in combination with the valve device O-ring 12 for preventing the leakage of the extinguishing agent on the upper side of the body (3) Coupled with the push bolt (10) located in the upper end of the device (2) and the valve device 20, the nut cap 11 and the check valve (20) for coupling with the valve device (2) capable of controlling the discharge of the extinguishing agent And a check valve cap 40 or a pressure gauge coupled to the check valve 20 and coupled with a check valve 20 connected to one side of the fire detection tube 30 and the fire detection tube 30 to maintain a constant pressure. It is achieved by a fire detection tube-mounted automatic fire extinguishing device (1) formed, including (3).

The present invention relates to a fire detection tube-mounted automatic fire extinguishing device (1), using a fire detection tube-mounted automatic fire extinguishing device (1) is difficult to extinguish fire or small spaces, corners and the like, fire detection device And it is easy to install in a place where the fire suppression apparatus is difficult to install, and can be installed to the nearest place where the fire can occur, so that the fire can be detected at the beginning of the fire and the fire can be suppressed.

In the absence of the check valve 20, the fire detection tube 30 is a mixture of a pressure-extinguishing agent and a pressurized gas such as nitrogen at a predetermined pressure and air, so that the temperature detected by the fire detection tube 30 is not constant. There is a problem of causing corrosion, such as corrosion in the fire detection tube 30 due to the mixing of the pressurized gas, such as nitrogen of the fire detection tube 30 due to the check valve 20 to maintain a constant pressure and detection temperature Maintained and filled with nitrogen gas only has the advantage of preventing the corrosion of the fire detection tube (30).

Fire extinguishing agent 30 is not stored in the fire detection tube 30 due to the check valve 20 because the fire detection tube 30 does not belong to a storage container that requires the certification of Korea Fire Protection Corporation. In the case of the detection tube 30, inspection and certification are not necessary, thereby preventing the production cost of the product from being increased due to the replacement of the fire detection tube 30 conforming to the standard.

In addition, when there is no check valve 20, the pressure and extinguishing agent flows into the fire detection tube 30, and there is a difficulty in desorption after attaching. However, due to the combination of the check valve 20 can be easily separated at any time between the fire extinguisher and the fire detection tube 30 is effective.

According to the present invention, in order to recognize a fire occurrence to a user who uses the fire detection tube-mounted automatic fire extinguishing device (1) at the time of fire, the pressure detecting device (5) transmits the pressure inside the cylinder to the controller as an electrical signal to generate a fire alarm. In the case of the siren and the indicator, the fire alarm is notified through the sound and the light of the indicator, and in the case of the wired / wireless communication interface, the device is connected to an external terminal through the wired / wireless communication interface to generate a fire. There is a feature to inform whether or not.

The present invention forms a valve device (2) including a push bolt (10) and a nut cap (11) capable of controlling the outflow of the extinguishing agent by rotating from the upper side to the lower side of the valve body (3) in an open and locked state. If the handle (lever) is installed to maintain the pressure, the upper handle is easily rotated to the lower side by the handle operation by the external force of ordinary people or children, and the opening and closing of the moving passage of the extinguishing agent is controlled, and the lock state becomes easy The fire detection tube attached type automatic fire extinguishing device (1) does not work, it is possible to prevent such a malfunction.

These and other objects and features of the present invention will be more clearly understood from the following detailed description based on the accompanying drawings.

A combined perspective view and an exploded perspective view of a fire detection tube-mounted automatic fire extinguishing device, Figure 8 is a fire detection tube-mounted automatic fire extinguishing device including a pressure gauge according to the present invention It shows a longitudinal sectional view.

1 to 3, the present invention fire detection tube attached automatic fire extinguishing device (1) is coupled to the cylinder (6) containing a fire extinguishing agent, the pressure gauge (4) and pressure detecting device for measuring the pressure ( 5) The valve body 3 is coupled to both sides of the valve body 3, and the upper side of the valve body 3 forms a push bolt 10 coupled with the valve device O-ring 12 for preventing leakage of the extinguishing agent and the valve body 3 One side of the) is coupled to the valve device (2) and the push bolt 10 located on the upper end of the valve device 20 is configured to be coupled to the check valve 20, the nut cap (11) capable of controlling the outflow of the extinguishing agent And a check valve 20 coupled to the valve device 2 and a check connected to one side of the fire detection tube 30 and the fire detection tube 30 which maintains a constant pressure and is coupled to the check valve 20. It includes a check valve cap 40 coupled to the valve 20.

Instead of the combination of the push bolt 10 and the nut cap 11, the handle (lever), etc. installed to maintain the open and locked state by rotating from the upper side to the lower side at the top of the valve body is installed on the external force of the general public or children By the handle operation by the upper handle is easily rotated to the lower side, the opening and closing of the moving passage of the extinguishing agent is controlled, and easily locked, the fire detection tube attached type automatic fire extinguishing device (1) may not operate in case of fire. The push bolt 10 coupled with the valve device O-ring 12 for preventing leakage of the extinguishing agent on the upper side of the valve body 3 and the upper end of the push bolt 10 are combined with the push bolt 10 to extinguish the chemical. Such a malfunction can be prevented by forming the valve device 2 including a nut cap 11 capable of controlling the outflow of the valve.

The pressure gauge 4 visually displays the pressure inside the cylinder 6, and the pressure detecting device 5 transmits the pressure inside the cylinder 6 to the controller as an electrical signal to the fire generation alarm device 7. If the pressure abnormality occurs inside the cylinder (6), it can be recognized by the user.

The check valve 20 for preventing the mixing of the pressurized gas such as nitrogen and the extinguishing agent shown in FIG. 4 is formed as follows.

The check valve 20 forms a cylindrical tube through which the extinguishing agent can pass through the body 21 of the check valve, and the needle 25 coupled with the spring 24 in the check valve body 21. Forming a check valve o-ring 23 to prevent leakage of pressure to maintain a constant pressure inside the fire detection tube 30 on both sides of the combination of the spring 24 and the needle 25, It includes a sleeve 22 which is coupled to the fire detection tube (30).

The sleeve 22 is a component having a cylindrical shape used to fit on the outer circumference of one side of the check valve body 3 to induce coupling with the fire detection tube (30).

When there is no check valve 20, the fire detection tube 30 is a mixture of a fire extinguishing agent and a pressurized gas such as nitrogen of a certain pressure and air, so that the temperature detected by the fire detection tube (30) is not constant and extinguishing agent, etc. Due to the mixing of the fire detection tube 30 causes corrosion, etc., but because of the check valve 20, the fire detection tube 30 is filled with only a pressurized gas such as nitrogen to maintain a constant pressure and detection temperature constant To prevent corrosion.

In addition, when there is no check valve 20, the pressure and extinguishing agent flows into the fire detection tube 30, and there is a difficulty in desorption after attaching. However, due to the combination of the check valve 20 can be easily separated at any time between the fire extinguisher and the fire detection tube (30).

The inside of the fire detection tube 30, which is filled with a pressurized gas such as nitrogen at a constant pressure, is formed as follows.

The material of the fire detection tube 30 is any one of nylon, silicon, plastic, and the like, and the inside of the fire detection tube 30 is filled with a pressurized gas such as nitrogen at a constant pressure to prevent corrosion by chemical reaction. Safe, and the temperature detected by the fire detection tube (30) is always constant.

In more detail, when the fire extinguishing agent enters inside the fire detection tube 30, a fire extinguishing agent which is a mixture of hydrogen, carbon, fluorine, etc. may cause a chemical reaction with the fire detection tube 30, and When the fire detection tube 30 can be corroded by the bar when corrosion occurs, the fire detection tube 30 is aged and shortened its lifespan, and as the fire extinguishing agent is stored in the fire detection tube 30, the fire detection tube (30) also belongs to a storage container that requires the certification of the Korea Fire Protection Corporation. When the Korea Fire Protection Corporation is certified, only the fire detection tube (30) needs to be inspected and certified, and replaced with a fire detection tube (30) that meets the standard. In this case, the production cost of the product is increased.

And, the fire detection tube 30 should always be maintained at a constant temperature and operated at a constant temperature, but when the fire extinguishing agent is filled in the fire detection tube, if the extinguishing agent corresponds to a mixed chemical, the specific heat of the extinguishing agent is high. Thermal energy is conducted to the fire extinguishing agent in the tube, so it is not sensitive to fire in case of fire, and the temperature is not constant because the specific heat varies depending on the composition, mixing ratio and specific heat of each extinguishing agent. In addition, when the fire extinguishing agent is filled in the fire detection tube 30, the extinguishing agent is precipitated due to unused for a long time, so that the concentration difference between the portion with and without the drug in the fire detection tube 30 occurs and the sensing temperature is constant. You will not.

In addition, when the chemical is stored in the fire detection tube 30, the amount of extinguishing agent in the cylinder 6 is larger than the amount of extinguishing agent filled in the cylinder 6 because the chemical is stored in the fire detection tube 30. Should be filled with fire extinguishing agents.

Looking more closely at the fire detection tube 30, the fire detection tube 30 maintains a constant air pressure, for example, about 10 atm through pressurized gas such as nitrogen, and 9 atm for the extinguishing agent in the cylinder (6). When the fire occurs when the fire detection tube 30 is melted, the pressure of the fire detection tube 30 is at atmospheric pressure, whereby a high-pressure extinguishing agent filled in the cylinder 6 is fired. It is injected through the molten portion of the sensing tube 30 to extinguish the fire initially.

A fire detection tube-mounted automatic fire extinguishing device 1 having a check valve cap 40 replaced with a pressure gauge 4 is formed as follows.

The fire detection tube-mounted automatic fire extinguishing device 1 shown in FIGS. 6 to 8 is coupled to a cylinder 6 containing a fire extinguishing agent, and includes a pressure gauge 4 and a pressure detector 5 for measuring pressure. Each of the valve body 3 is coupled to the valve body 3 on both sides, and the upper side of the valve body 3 forms a push bolt 10 coupled with the valve device O-ring 12 for preventing leakage of the extinguishing agent. A valve cap 2 configured to be coupled to the check valve 20 and a push bolt 10 positioned at an upper end of the valve apparatus 20 may be coupled to a nut cap 11 and the valve may control the outflow of the extinguishing agent. A check valve 20 coupled to the apparatus 2 and a fire detection tube 30 coupled to the check valve 20 and maintaining a constant pressure and a check valve 20 connected to one side of the fire detection tube 30. It is formed by including a pressure gauge (4) instead of the check valve cap 40 to be coupled to the).

By replacing the check valve cap 40 by combining the check valve 20 and the pressure gauge 4 through the check valve nut 50, the user using the fire detection tube-mounted automatic fire extinguishing device 1 can be easily It can be confirmed whether the pressure inside the fire detection tube 30 is kept constant.

Forming including any one of.

In more detail, when the fire detection tube 30 is melted due to a fire, a pressure drop occurs and the extinguishing agent is ejected accordingly, so that the pressure detection device 5 converts the pressure inside the cylinder 6 into an electrical signal. It is transmitted to the controller to be displayed on the fire alarm system (7). In the case of siren and indicator, the fire alarm is notified through the sound and light of the indicator, and in the case of a wired / wireless communication interface, Connected with the terminal will notify whether a fire has occurred.
