Description

Water Pressure Control Nozzle for Fire-fighting}

The present invention relates to a waterproof pressure control connecting pipe window for fire fighting, and more particularly, is installed at the rear end of the existing pipe window to prevent the safety accident by directly adjusting the waterproof pressure in the field, and provided with an overpressure preventing means to suddenly overpressure the fire hose If it is applied, it is appropriately removed to promote the safety of firefighters, and if it is necessary to extend the fire hose during the firefighting activity, the firefighters in the firefighting unit should be provided with a structure to control the water so that the fire hose can be extended alone. Fire-proof waterproof pressure control connecting window to allow fire fighters to perform fire suppression alone without having to communicate with fire crews waiting in the fire truck in crowded situations such as fire at night, narrow alleyways or large buildings. It is about.

In general, the fireman's window refers to a device for the firefighters to inject fire extinguishing fluid for extinguishing the fire. Conventional fireman's windows are usually connected to one end of the fire hose to control the fire extinguishing fluid delivered from the fire truck so that it can be waterproof or cut off. It is structure to suppress. The pipe can simply change the form of direct weaving or spraying, there is a lot of inconvenience due to the lack of means for adjusting the waterproof pressure. That is, in order to adjust the waterproof pressure by the conventional pipe, there is no choice but to adjust the valve provided in the fire truck, in this case there is a problem that the waiting personnel must always reside in the fire truck. In case of increasing the waterproofing pressure by communicating with firefighters waiting in the fire truck, it is not easy to adjust the waterproofing pressure appropriately for the suppression firefighters. This can lead to an overwhelming fighter's stamina or an accident, such as a fall of firefighters on the railing of a high rise building.

In addition, according to the conventional pipe connected to the fire hose in which the extinguishing fluid is injected at high pressure, there is a case in which the fire hose shakes due to the injection pressure through the pipe in the process of waterproofing. That is, when the injection pressure is increased to spray water on a high floor or a long distance, overpressure is momentarily applied to the fire hose, which may cause an indifferent danger to the firefighter. In other words, firefighters with a small build or weak force, such as women, may drop the fire hose due to overpressure. In this case, the body may be injured by the fire hose and the pipe.

In addition, the fire fighting by the conventional firefighter window is to be carried out by a pair of two firefighters, one person to open and close the water supply valve of the fire engine or to adjust the injection pressure valve of the fire extinguishing liquid while waiting in the fire truck, The other person comes to the flower garden with a fire hose connected to the window. Firefighters usually communicate with each other by radio. When the firefighters approaching the firefighters are ready to extinguish the fire, the firefighters remaining in the fire truck are notified by the radio. Open it and proceed with digestion.

In the case of fires in narrow alleys, highlands, or large buildings where the fire trucks are not near, and in the event of a fire at night or in the basement, the fire hose may need to be extended. Fire fighters must go through the radio to contact other firefighters on fire trucks. That is, in case of existing pipe gutter, it is impossible to separate the gasket from the fire hose due to the water pressure during the fire suppression. After closing the water supply valve of the fire truck and exhausting the extinguishing fluid remaining in the fire hose, the gasket is separated and the other fire fighting It is possible to extend the hose. According to the conventional method of extending the fire hose using the pipe, the process of separating the pipe after exhausting the extinguishing fluid of the fire hose after the water supply valve is blocked by the fire crew of the fire engine, so that the fire extinguishing fluid remaining in the fire hose There is a problem of unnecessary waste, and there is also a problem that one firefighter must wait in the fire truck. In particular, when a large fire occurs, several fire trucks are dispatched, and up to eight fire hoses can be connected to each fire truck, and it is necessary to distinguish and connect fire hoses that require extension among several fire hoses in an urgent situation. Difficulties will follow.

The fire protection pipes disclosed in Korean Utility Model Publication No. 20-0270127 (Registration Date: 2002.03.18.) And No. 20-0273901 (Registration Date: 2002.04.18.) Are equipped with ball valves through which the extinguishing fluid passes. By providing an open / close lever on the outside, the open / close lever is interlocked with the ball valve provided therein, so that the firefighters on the scene who extinguish a fire when the extension of the fire hose is necessary use the ball valve to interlock with the open / close lever immediately. The fire hose is disconnected and the fire hose is connected. However, the above technique has a problem that the rubber packing adjacent to the ball valve and the rubber packing adjacent to the ball valve by the repeated operation of the opening and closing the valve is aging and leaks, if the foreign matter is caught between the ball valve and the rubber packing cause a failure. There is a problem that can be. In addition, the technique can simply extend the fire hose, there is a limit that can not properly adjust the waterproof pressure by the firefighter or prevent overpressure that may occur unexpectedly.

Fire-fighting windows disclosed in Korean Utility Model Publication No. 2009-0009830 (published date: 2009.309.30.) Immediately extend the fire hose at the fire site as the disc seat opens and closes the flow path by sliding rotation between the nozzle body and the borrowing part. I'm trying to. However, the above technique merely allows the fire hose to be extended in the field and does not have a configuration for adjusting the waterproof pressure or preventing overpressure. Even if a fire hose can be connected at the fire site, failure to properly adjust the waterproofing pressure for the firefighters or to remove the overpressure applied instantaneously will cause the firefighters to consume much energy and may be exposed to inadvertent danger. Therefore, it is necessary to effectively control and disperse the pressure applied to the fire hose during the firefighting.

That is, when the nozzle body 10 and the charging unit 20 are spaced apart from each other by a predetermined distance d, as shown in FIG. 2A or FIG. 2B, the first disc sheet 31a is in close contact with the nozzle body 10. ) Closes the flow path, and when there is no separation distance as shown in Figure 2c, the first disc sheet 31a is separated from the contact portion 13 to open the digestive fluid flow path.

Figure 3 is a view showing the assembly of each component of the waterproof pressure control connecting pipe window according to the present invention, Figure 4 is a spindle 30 and the overpressure prevention rod 40 is coupled to the inside of the connecting pipe window for fire fighting As shown in the figure, it can be seen that the spindle 30 and the overpressure preventing rod 40 are drawn in at the front end of the nozzle body 10 and the rear end of the charging unit 20, respectively, and are coupled therein. Spindle 30 is to act to open and close the flow of the digestive fluid in the digestive fluid flow path of the connecting pipe window for the fire according to the present invention, the first disk seat 31a located at the front end of the spindle inside the front end of the nozzle body 10 By being in close contact with the close contact portion 13 provided in the flow of the digestive fluid is blocked. The spindle 30 is provided with a spindle fastening bolt 32 on the outside of the rear end, the spindle 30 is inserted from the front end of the nozzle body 10 and the spindle fastening nut (retracted from the rear end of the charging unit 20) 33) and screwed in. According to the present invention, the flow distance d between the nozzle body 10 and the charging unit 20 is limited by the combination of the spindle fastening bolt 32 and the fastening nut 33. That is, the rotation of the spindle fastening bolt 32 and the fastening nut is rotated by screwing the charging part nut 11 formed inside the rear end of the nozzle body 10 and the charging part bolt 21 formed outside the charging part 20. It is limited within a certain range by the combination of (33). Referring to FIG. 6, a locking jaw 24 is formed at a predetermined depth inside the charging unit 20, and the spindle fastening nut 33 inserted into the rear end of the charging unit 20 is connected to the locking jaw 24. When the spindle fastening nut 33 is coupled to the spindle fastening bolt 32 in a limited state of locking by the locking jaw 24, the flow distance d of the nozzle body 10 and the charging unit 20 is increased. Will be limited.

To be fitted to. The second disk sheet 31b according to the present invention has a diameter slightly longer than that of the first disk sheet 31a, so that the second disk sheet 31b can react with excessive pressure.

 The pressure control unit 41 is characterized in that a groove of a predetermined depth is formed so as to respond to the water pressure, the pressure control unit 41 is provided with an overpressure preventing rod 40 is a reaction in the state that the waterproofing is blocked. However, if excessive pressure occurs suddenly during waterproofing, it is characterized in that it reacts. That is, when overpressure occurs during waterproofing, pressure is applied to the groove of the pressure adjusting part 41 formed at the rear end of the overpressure preventing rod 40, and the overpressure preventing rod 40 is spring 60 by the pressure. The contraction of the extinguishing fluid is caused by contracting, and as a result, the second disc sheet 31b positioned above the spindle 30 is pushed up to block a part of the extinguishing fluid flow path of the space 14 formed inside the distal end of the nozzle body 10. By weakening the flow, it is possible to prevent an increase in the waterproof pressure. That is, referring to FIG. 6B or 6C, in the state where the water pressure is constant, the extinguishing liquid is in the space 14 of the nozzle body 10 in a state where the second disc sheet 31b is in close contact with the first disc sheet 31a. When the overpressure is instantaneously applied due to an increase in the injection pressure valve or a malfunction, the overpressure is transmitted to the pressure regulating portion 41, which causes the spring 60 to flow. The second disk sheet 31b, which is contracted and is formed longer than the first disk sheet 31a, is pushed by the flowing digestive fluid, so that the digestive fluid flow path b is narrower than before. It can be prevented to mitigate the impact. The space portion 14 provided at the front end of the nozzle body 10 according to the present invention is to ensure a space for smoothly flowing the digestive fluid and at the same time to free the flow of the spindle 30, the space portion ( 14) during the waterproofing, the digestive fluid flows smoothly, and when the waterproof pressure suddenly rises, the second disk sheet 31b of the spindle 30 flows to weaken the extinguishing fluid flow, thereby preventing the increase in the waterproof pressure. .

Conventional windows can be changed only in the form of direct weaving or spraying, it is a structure that can not adjust the waterproof pressure. Water pressure control is a very important issue during fire suppression. If the water pressure control is not smooth, firefighters may not only be inadvertently harmed, but may be determined by the type and nature of the fire. In other words, if the water pressure control is not timely, there may be a risk depending on the sex, physical condition, or the condition of the firefighters.For example, a firefighter may fall from a high-rise railing due to excessive water pressure. Can be. In addition, the property of the fire may change from time to time in the case of hay piles or high-rise buildings filled with high ceilings and combustibles, so it may be difficult to extinguish the fire if the water pressure is not properly adjusted. have. After connecting and installing the connection pipe window for fire fighting according to the present invention to the rear end of the existing pipe window, when the nozzle body 10 and the charging unit 20 are mutually rotated to properly adjust the separation distance d, the internal spindle 30 is By interlocking and controlling the flow path of the digestive fluid flowing through the space portion 14, it is possible to directly adjust the waterproof pressure in the field.

5 is a first disc seat 31a of the second disc seat 31b of the spindle 30 coupled to the inside of the waterproof fire pressure control tube window according to the present invention as the overpressure prevention rod 40 is relaxed and contracted. The second disk sheet 31b according to the present invention is characterized in that the diameter of the second disk sheet 31b is slightly longer than that of the first disk sheet 31a. When the overpressure is generated, the pressure adjusting part 41 formed at the rear end of the overpressure preventing rod 40 reacts, and the spring 60 contracts. In this case, the second disk sheet having a long diameter by the extinguishing fluid flowing through the digestive fluid flow path ( 31b) is pushed away from the first disk sheet 31a to narrow the flow path of the space portion 14, thereby weakening the flow of the extinguishing fluid flowing, thereby preventing an increase in the waterproof pressure. According to the present invention, when the overpressure preventing rod 40 is contracted by overpressure, a rubber ring 42 is further provided on the overpressure preventing rod 40 to prevent leakage of the digestive fluid through the fitting hole 34. It will be provided.

Figure 6 is a view showing a cross-section of the waterproof pressure control connecting pipe window according to the present invention, the nozzle body and the charging portion spaced apart from each other the state in which the spindle closed the digestive fluid passage (Fig. 6a), the digestive fluid passage is opened (Fig. 6b) ) And the second disk sheet 31b is separated from the first disk sheet 31a due to the overpressure applied during waterproofing (Fig. 6C). When the extension of the fire hose is required when using the fire connection pipe window according to the present invention, as shown in Figure 6a by separating the nozzle body 10 and the charging unit 20 by the spindle to block the digestive fluid flow path The firefighters should be able to extend the fire hose immediately on site. When the nozzle body 10 and the charging unit 20 are in close contact with each other, as shown in FIG. 6B, the first disc seat 31a of the spindle 30 is formed in the front end of the nozzle body 10. It is separated from the 13) the flow path is opened is made waterproof. When sudden overpressure occurs during the waterproofing of the digestive fluid, the overpressure is applied to the pressure adjusting part 41 of the overpressure preventing rod 40, and the overpressure preventing rod 40 is pushed by the force and the spring ( 60) will contract. As a result of the contraction of the spring 60, the force used to fix the second disc sheet 31b disappears. As a result, the second disc sheet 31b having a diameter larger than that of the first disc sheet 31a is caused by the pressure of the extinguishing fluid. ) Is pushed by the force of the digestive fluid and separated from the first disk sheet 31b. FIG. 6C is a view showing a state in which the second disc sheet 31b is separated from the first disc sheet 31a by applying overpressure. According to FIG. 6C, the flow path is caused by the second disc sheet 31b separated by the overpressure. As (b) is narrowly formed, the amount of digestive fluid flowing is reduced, and as a result, it can be seen that it may have an effect of reducing the water pressure. The front end of the charging portion 20 according to the present invention is further provided with a rubber ring 22 to prevent leakage of the digestive fluid.

Figure 7 is a cross-sectional perspective view of one side of the waterproof pressure control connecting pipe window according to the present invention, showing a state in which the flow of the extinguishing fluid is blocked in a state in which the nozzle body 10 and the charging portion 20 is spaced apart.
