Description

VALVE STRUCTURE AND FIRE SUPPRESSION SYSTEM INCLUDING THE SAME

The present disclosure relates to a valve structure and a fire suppression system including the same, and more particularly, to a valve structure for quickly extinguishing a fire by automatically driving a fire extinguisher by sensing an environment related to a fire, and a fire suppression system including the same will be.

As high-rise buildings appear due to the development of construction technology, technologies for preventing disasters occurring in high-rise or high-rise buildings or minimizing damage caused by disasters are being developed together. In particular, as the density of residential spaces and shops in high-rise buildings increases, a fire that occurs in one space may spread in a chain to other parts of the building, causing great damage. For example, in the case of a mixed-use building, if a fire that occurred on one floor is not extinguished at an early stage, great damage may occur to the entire building. As such, it is very important to extinguish a fire at the beginning of its occurrence, and if the fire expands due to failure in the initial firefighting, it is difficult to extinguish the fire and large property loss occurs.

In general, as a fire suppression system for detecting and suppressing a fire, there are fire detectors and sprinklers installed on the ceiling or wall of a building, or fire extinguishers and fire hydrants disposed in various places inside the building. The fire detector detects heat, smoke, etc. caused by a fire through a fire detection facility such as a heat sensor and a smoke sensor, and operates an alarm sound or a warning light to warn people about the occurrence of a fire.

However, in the case of a conventional fire suppression system, fire suppression may not be appropriate in an unmanned environment. For example, a general fire suppression system is not appropriate as an early warning measure for a fire that occurs in the absence of a person because a person who can check the fire alarm or warning light can take action to extinguish the fire only when the person who can see it is aware of it. may have limitations.

In addition, a general fire extinguisher is configured such that the extinguishing liquid is built into the internal storage space, and in case of a fire, the user directly presses the handle of the fire extinguisher to spray the extinguishing liquid inside the storage space to the outside. That is, a general fire extinguisher has a problem in that the user must remove the safety pin, direct the hose to the place of the fire, and directly manipulate the handle to extinguish the fire, so that the user has to rely only on the user's operation. Additionally, there is a possibility of causing injury to the user in the process of extinguishing a fire through a fire extinguisher. As such, the conventional system has a problem in that it is not possible to operate the fire extinguishing equipment if the user is not in the field, so that proper initial action for a fire is not made.

Here, the vertical movement (or vertical movement) may mean that, as shown in FIG. 5 , the injection unit 1200 moves upward or downward according to the pressure inside the inner passage 1111 . For example, (a) of FIG. 5 may show the location of the spraying unit 1200 before the operation of the fire extinguishing unit 100 starts when no fire occurs, and FIG. 5(b) is When the fire extinguishing unit 100 operates as a fire occurs, the location of the spraying unit 1200 exposed to the outside may be indicated.

According to an embodiment, the head unit 1210 may include a buffer for dispersing the impact applied to the injection unit 1200 . The buffer unit may be provided on one surface of the head unit 1210 . When the buffer part rises upward based on the pressure in FIG. 5, the head part 1210 and the body part (ie, the injection site support surface 1122) through the buffer part formed on one surface of the head part 1210. impact can be minimized. For example, the buffer unit may be provided through at least one material of silicone, rubber, and urethane. However, the buffer part is not limited to the above-mentioned materials, and the material of the buffer part includes various materials for dispersing the mechanical shock generated when the head part 1210 and the body part 1100 come into contact with each other through a preset elastic modulus. can do.

As a specific example, when a fire occurs, the extinguishing agent may be supplied to the inner passage 1111 of the body 1100 through the connection 2200, and the injection unit 1200 rises as the internal pressure rises. It can be exposed to the outside as in (b) of 5. In this case, the body unit 1100 supports the head unit 1210 through the injection site support surface 1122 , thereby preventing the injection unit 1200 from completely leaving the fire extinguishing unit 100 .

Here, since the exposure of the injection unit 1200 is achieved through an increase in pressure, damage to the device may be caused due to the impact generated during the contact process between the head unit 1210 and the injection site support surface 1122 .

Here, one end of the central hole 1230 may mean one end corresponding to the head portion 1210 . In this case, an injection protrusion support surface 1231 may be provided at one end of the center hole 1230 to prevent complete separation of the injection projection 1240 .

As shown in FIG. 4 , the injection protrusion 1240 is provided to pass through one end of the central hole 1230 , and is provided to be fixed through the injection projection support jaw 1241 and the injection surface 1242 to move within a predetermined range. This may be possible. Here, the movement within a predetermined range may mean a movement within the injection protrusion support jaw 1241 and the injection surface 1242 .

The injection protrusion 1240 may be provided to protrude from the length 1220 to open the central hole 1230 extending to one end of the length 1220 .

When the injection protrusion 1240 rises so that the injection projection support jaw 1241 comes into contact with the injection projection support surface 1231 formed at one end of the central hole 1230, the injection projection 1240 is the center hole 1230 and Through the gap, it forms a passage for the discharge of the extinguishing agent. For example, a diameter of the injection protrusion 1240 between the injection protrusion supporting jaw 1241 and the injection surface 1242 may be smaller than a diameter formed by the central hole 1230 . Accordingly, the extinguishing agent may be discharged through a passage secured according to the difference in diameter between the injection protrusion 1240 and the center hole 1230 .

The extinguishing agent may be discharged through a passage secured through a gap between the injection protrusion 1240 and the center hole 1230 . In this case, the diameter of the injection protrusion 1240 passing through the central hole 1230 is smaller than the central hole 1230, and as it is fixed to the injection unit 1200 through the injection projection support jaw 1241, the fire extinguishing agent is In the discharge process, the injection protrusion 1240 may have movement at various angles based on the length 1220 . Accordingly, the extinguishing agent has an effect that can be sprayed in more directions.

Additionally, when the fire extinguishing agent is discharged through the passage formed as the injection protrusion 1240 rises from the injection unit 1200, the discharged fire extinguishing agent hits the injection surface 1242 formed on the upper side of the injection projection 1240. will spread all over the place. In this case, the injection protrusion 1240 may discharge the extinguishing agent in various angle ranges according to the movement at various angles based on the length 1220 in the process of discharging the extinguishing agent, and additionally the spraying surface 1242. Through the "??* injection can be made. In other words, it can be possible to discharge the extinguishing agent in a wider range by using the injection surface 1242.

That is, the corner portion 1231 may form a spray angle of a certain range so that the discharged extinguishing agent has directivity.

Also, the injection unit 1200 may include a center hole 1210 formed along the inner longitudinal direction of the head unit 1220 and the length unit 1230 and connected to the plurality of perforations 1232 . That is, the central hole 1210 may be formed to pass through the injection unit 1200 in the longitudinal direction of the length portion 1230 to be connected to each of the plurality of perforations 1232 and the corner portions 1231 . In other words, each of the plurality of perforations 1232 and the corner portions 1231 may be connected to the central hole 1210 formed in the longitudinal direction. Accordingly, the extinguishing agent may be supplied in the direction of the head portion 1220 and discharged through the plurality of perforations 1232 and the corner portions 1231 through the center hole 1210 .

That is, when the fire extinguishing agent is supplied to the inner passage 1111 of the body portion 1100 through the connection portion 2200, the opening and closing portion 1400 is opened by the movement of the injection portion 1200 generated as the internal pressure rises. and the injection unit 1200 may be raised to the open upper end to be exposed to the outside. The spraying unit 1200 exposed to the outside discharges the extinguishing agent in all directions through the corner portion 1231 and the plurality of perforations 1232 , so that the fire extinguishing unit 100 corresponds to a predetermined area (eg, provided area). suppression can be performed.

The central hole 1210 is formed to pass through the length 1230 from the head part 1220 , and the central hole diameter 1210a may be formed smaller than the head part diameter 1220a. Also, the outer diameter of the head 1220 may be smaller than the diameter of the inner passage 1111 formed by the body 1100 . For example, when the inner diameter of the inner passage 1111 is 2 cm, the diameter of the head part 1220a may be 1.9 cm. The specific numerical description related to the above-mentioned diameter is only an example, and the present disclosure is not limited thereto.

That is, as the head portion 1220 of the injection unit 1200 is provided to have a smaller diameter than the inner passage 1111, the injection unit 1200 moves up and down according to the pressure generated inside the inner passage 1111 ( Alternatively, vertical movement) may be performed. That is, the inner passage diameter 1111a may be larger than the head minor diameter 1220a.

Here, the vertical movement (or vertical movement) may mean that, as shown in FIG. 13 , the injection unit 1200 moves upward or downward according to the pressure inside the inner passage 1111 . For example, (a) of FIG. 13 may show the position of the injection unit 1200 before the operation of the fire extinguishing unit 100 when no fire occurs, that is, the location of the injection unit 1200 before the operation of the fire extinguishing unit 100. Accordingly, when the fire extinguishing unit 100 operates, the position of the spray unit 1200 exposed to the outside may be indicated.

According to an embodiment of the present disclosure, the head unit 1220 may include a buffer unit 1222 for dispersing the impact applied to the injection unit 1200 .

For example, the buffer unit 1222 may be provided through at least one material of silicone, rubber, and urethane. However, the buffer part is not limited to the above-mentioned materials, and the material of the buffer part may include various materials for dispersing the mechanical shock generated when the head part 1220 and the bearing 1300 come into contact with each other through a preset elastic modulus. can

For a specific example, when a fire occurs, the extinguishing agent may be supplied to the inner passage 1111 of the body 1100 through the connection portion 2200, and the opening and closing portion 1400 is opened as the internal pressure rises and the injection portion 1200 may be raised and exposed to the outside as shown in FIG. 13(b). In this case, the bearing 1300 may be supported through the inner support jaw 1122b of the second body portion 1120 , and it is possible to prevent the injection unit 1200 from completely leaving the fire extinguishing unit 100 . have. The bearing 1300 may include a through hole 1300a having a diameter larger than the outer diameter of the length 1230 but smaller than the diameter 1220a of the head part 1220 of the head part 1220 . Accordingly, when the injection part 1200 is raised by pressure, only the length part 1230 can be exposed to the outside while preventing the injection part 1200 from coming into contact with one surface of the head part 1220 to the outside. have. Here, since the exposure of the injection unit 1200 is achieved through an increase in pressure, the device may be damaged due to an impact generated during the contact between the head unit 1220 and the bearing 1300 .

Accordingly, when the injection part 1200 is exposed to the outside by pressure, a buffer part 1222 made of a buffer material may be provided on one surface of the head part 1220 in contact with the bearing 1300 . This may have the effect of securing the stability of the device as it is possible to minimize the impact caused by the contact between the bearing 1300 and the head unit 1220 . That is, damage to the injection unit 1200 or the bearing 1300 is prevented through the buffer unit 1222 , thereby improving the operating efficiency of the device.

According to an embodiment of the present disclosure, the head unit 1220 may include a movement guide unit 1223 . Specifically, the head portion 1220 may include a movement guide portion 1223 extending along the longitudinal direction of the inner passage 1111 and at least a portion of the inner peripheral surface of the inner passage 1111 is formed to be in contact.

For example, the movement guide part 1223 may be provided to extend through a predetermined length in a part of the head part 1220 . Accordingly, the head portion 1220 may include a movement guide portion 1223 provided to extend through a predetermined length in a direction opposite to the direction in which the length portion 1230 extends, that is, in another direction opposite to one direction. can

For a specific example, referring to FIG. 14 , at least a portion of the head portion 1220 may include a movement guide portion 1223 formed to protrude in a direction opposite to the direction in which the length portion 1230 is formed.

In the movement guide unit 1223 of the present disclosure, when the injection unit 1200 moves in an upward direction or a downward direction by pressure, the head unit 1220 is disposed in the inner passage 1111 formed by the body unit 1100. This may be to prevent damage that may be caused by being twisted into place.

For a specific example, when a fire occurs, the extinguishing agent may be supplied to the inner passage 1111 of the body 1100 through the connection portion 2200, and the opening and closing portion 1400 is opened as the internal pressure rises and the injection portion 1200 may be raised and exposed to the outside. In this case, as the injection unit 1200 performs a vertical motion (or vertical movement) through the pressure generated by the supplied extinguishing agent, the head unit 1220 moves through the inner passage while the injection unit 1200 is raised. It can be twisted into a part of (1111). In order to prevent this, a movement guide part 1223 may be provided on a part of the head part 1220 . That is, as the movement guide part 1223 is provided in the direction extending in one direction from the head part 1220 (eg, in the opposite direction of the length part), as the contact area with the inner wall of the inner passage 1111 is improved, the inner The inclination of the injection unit 1200 in the passage 1111 may be prevented. In other words, the movement guide unit 1223 may provide an effect of preventing damage to the device by guiding the head unit 1220 so that the injection unit 1200 performs a smooth vertical movement within the inner passage 1111 .

According to an embodiment of the present disclosure, the injection unit 1200 may include a spring unit 1240 that applies a restoring force to the head unit 1220 . Specifically, the injection unit 1200 may include a spring unit 1240 having one end connected to one surface of the head unit 1220 , the other end corresponding to one end connected to one surface of the bearing, and made of an elastic material. Here, the spring part 1240 may be formed to surround the outer surface of the length part 1230 through rotation between one end and the other end. For example, the spring part 1240 may be provided in the shape of a coil that surrounds the outer peripheral surface of the length part 1230 in a helical direction, as shown in FIG. 14A .

For example, when a fire occurs, the fire extinguishing agent is supplied to the internal passage 1122 through the connection unit 2200 through the gas supply unit 3000 under the control of the control unit 300, or the opening/closing unit 1400 located at the top ) can be opened. That is, the opening/closing unit 1400 may be opened based on the operation control signal of the control unit 300 , and the injection unit 1200 is exposed to the outside as the upper end opened by the internal pressure, and a plurality of perforations or corner units 1231 . It is possible to extinguish the fire by discharging the extinguishing agent in all directions through the After all operations for extinguishing the fire are performed (eg, when all of the extinguishing agent is discharged), when the injection unit 1200 is continuously exposed to the outside, it interferes with the walking of a moving user and causes an injury or There is a risk of causing injury to the user's body. Additionally, an external impact acts on the injection unit 1200 exposed to the outside to cause bending or damage to the injection unit 1200 , which may reduce the continuity of the device.

Accordingly, the spring part 1240 has a coil shape, and one end and the other end are respectively disposed between the head part 1220 and the first surface 1310 of the bearing 1300, and the injection part 1200 is formed in the body part ( 1100) may apply a restoring force to move it to the inside. That is, when the pressure acting on the inner passage 1111 and the injection unit 1200 decreases over time due to the continuous discharge of the extinguishing agent, the first surface 1310 of the head portion 1220 and the bearing 1300 ) due to the restoring force generated through the spring part 1240 disposed between the injection part 1200 may be moved into the inner passage 1111 , that is, the inside of the body part 1100 . Therefore, it can have an effect of preventing user injury or device damage that may occur after extinguishing a fire.

Specifically, the injection unit 1200 may include a dust film 1250 having one end connected to one surface of the head part, the other end corresponding to one end connected to one surface of the bearing, and provided through a cylindrical wrinkle structure. For example, the dust film 1250 may be provided through a cylindrical wrinkle structure surrounding the outer circumferential surface of the length portion 1230, as shown in (b) of FIG. 14 . In this case, the dust film 1250 may be for blocking the supply of the extinguishing agent discharged from the length portion 1230 to the inner passage 1122 . For example, the dust film 1250 may be formed through a thin vinyl film, and may have a wrinkled structure to minimize a volume in response to a force acting in the length portion 1230 direction (ie, a vertical direction).

Accordingly, it is possible to block the extinguishing agent discharged to the inner passage 1111, and when the injection unit 1200 is discharged to the outside for fire suppression, the first surface 1310 of the bearing 1300 and the head portion ( 1220) and may be positioned in a form with a minimized volume. In this case, the dust film 1250 may provide an effect of buffering an impact generated when the bearing 1300 and the head unit 1220 contact each other.

As a specific example, when the opening/closing part 1400 is opened, and the fire extinguishing agent is supplied to the inner passage 1111 of the body 1100 through the connection part 2200, the injection part 1200 according to the increase of the internal pressure. It can be raised and exposed to the outside of the opened device. The spraying unit 1200 exposed to the outside discharges the fire extinguishing agent in all directions through the central hole 1210 and the plurality of perforations 1232, thereby performing fire suppression corresponding to a predetermined area (eg, the provided area). . However, even when the injection unit 1200 is located in the inner passage 1111, the fire extinguishing agent may be discharged to the inner passage 1111 through the central hole 1210 and the plurality of perforations 1232 of the injection unit 1200. . That is, in the process of continuous use of the fire extinguishing unit 100 , dust or powder related to the fire extinguishing agent may be stacked on the inner passage 1111 , which may reduce the operating efficiency of the device. For example, there is a fear that the corrosion of the inner passage 1111 is accelerated through the fire extinguishing agent, or the vertical movement of the injection unit 1200 may not be smooth through the lamination of powder related to the fire extinguishing agent.

Accordingly, the dust film 1250 is disposed between the head portion 1220 and the first surface 1310 of the bearing 1300 through the cylindrical wrinkle structure, and the extinguishing agent discharged from the length portion 1230 is inside Supply to the passage 1111 may be blocked. That is, by providing a dust film 1250 disposed to surround the injection unit 1200 in the inner passage 1111, corrosion or abrasion through the fire extinguishing agent that may be generated inside the device in the process of continuous use of the device. Damage can be prevented.

Also, the bearing 1300 may include a through hole 1300a having an inner diameter corresponding to the diameter of the length 1230 and penetrating through the length 1230 . For example, when the diameter of the length portion 1230 is 1 cm, the inner diameter of the through hole 1300a passing through the length portion 1230 may be 1.1 cm. That is, as the length portion 1230 is provided through a smaller diameter than the through hole 1300a, it penetrates the bearing 1300 supported by the inner support jaw 1122b formed in the inner passage 1111 and can be exposed to the outside. have. That is, the head portion 1220 of the injection unit 1200 is supported on the first surface 1310 of the bearing 1300 , and only the length portion 1230 may be exposed to the outside through the through hole 1300a .

For example, when it is desired to form a hole (ie, a through hole) and a prevention surface (ie, the first surface) for performing the role of the bearing 1300 in the inner passage 1111, the difficulty of structural design, that is, the injection process difficulties may exist. The bearing 1300 of the present disclosure can be manufactured through a relatively simple process by forming a hole in the center, and can be disposed inside the body 1100 (that is, supported by the inner support jaw). Convenience in manufacturing or injection processes may be improved.

In this case, the bearing 1300 may be supported through the inner support jaw 1122b of the second body portion 1120 , and it is possible to prevent the injection unit 1200 from completely leaving the fire extinguishing unit 100 . have. In addition, the bearing 1300 may include a through hole 1300a having a diameter larger than the outer diameter of the length portion 1230 but smaller than the diameter of the minor head 1220a of the head portion 1220 . Accordingly, when the injection unit 1200 is raised by pressure, the first surface 1310 of the bearing 1300 is in contact with one surface of the head unit 1220 to prevent the injection unit 1200 from being separated to the outside. play a supporting role Here, since the exposure of the injection part 1200 (ie, the injection mechanism) is performed through an increase in pressure, it is an impact generated during the contact process of the head part 1220 and the first surface 1310 of the bearing 1300. This may cause damage to the device.

An impact prevention part 1311 of a cushioning material may be provided on the first surface 1310 of the . This may have the effect of securing the stability of the device by minimizing the impact caused by the contact between the bearing 1300 and the head unit 1220 during the operation of the injection mechanism for fire suppression. That is, damage to the injection unit 1200 or the bearing 1300 is prevented through the impact prevention unit 1311 , so that the operating efficiency of the device can be improved.

Specific description of the above-described coupling mechanism is only an example, and the present disclosure is not limited thereto. The opening/closing part 1400 may be opened by movement of the injection part 1200 according to the pressure application to the inside of the body part 1100 . According to an embodiment, the opening/closing unit 1400 may open the upper surface of the body unit 1100 based on an operation control signal of the controller 300 . For example, when the opening/closing part 1400 is opened, the pressure due to the supply of the extinguishing agent may be applied to the inner passage 1111 and the injection part 1200 , so that the injection part 1200 may be exposed to the outside of the device.

One or more supports are provided with a predetermined height (eg, a height corresponding to the length), and each support may have equal intervals. When one or more supports are in a closed state, the valve structure 1000 may be opened by being accommodated inside the body part 1100 and raising the opening/closing part 1400 together with the rising of the injection part 1200 . That is, when the injection unit 1200 is raised and exposed to the outside, the opening/closing unit 1400 may be disposed above the corresponding injection unit 1200 through one or more supports.

For example, since the injection unit 1200 includes a sharp corner portion 1231 , when the injection unit 1200 is exposed to the outside, there is a risk of causing injury to the user's body. Additionally, an external impact acts on the injection unit 1200 exposed to the outside to cause bending or damage to the injection unit 1200 , which may reduce the continuity of the device. As described above, when the injection unit 1200 is exposed to the outside to perform injection, the opening/closing unit 1400 may be disposed on the upper side of the injection unit 1200 through one or more supports, so that the injection unit 1200 is In addition, it is possible to provide an effect of preventing damage by protecting the injection unit 1200 exposed to the outside.
