Description

Device valve sealing device for gas fire extinguishers {Device for sealing a valve for a gas extinguisher}

The present invention relates to a vessel valve sealing device of a gas fire extinguisher, and more particularly, it is attached to a container of a gas fire extinguisher (for example, a halon fire extinguisher) and is operated in a fire so that the carbon dioxide gas in the container can be instantly released. It is designed to achieve a precise closing function even after a long period of time by improving the sheet performing the normal sealing function between the gas outlet in the form of a surface contact.

In general, the halon fire extinguishing system is a fire extinguishing system developed for use in a variety of fires, and this system is a liquid liquefied halon 1301 to be filled in a high-pressure gas container, stored in a pressurized state with nitrogen, Consists of halon cylinder, starting container, collecting pipe, valve header, selection valve, injection head and solenoid valve, and can open the container valve by automatic or manual operation and perform alarm and display function. It is a facility that can be done.

If a fire occurs in a location where such a Halon fire fighting system is installed, the Halon 1301 extinguishing agent is vaporized through the injection head and rapidly released and mixed into the air of the target fire, thereby achieving the purpose of extinguishing with a small concentration (about 5%). .

This type of equipment is classified into pressurized and accumulator type, and also divided into global emission method and local discharge method, and fire extinguishing methods of halon fire fighting system include 30 seconds and 10 seconds. This system was developed for the purpose of extinguishing fire, and it is an ideal fire extinguishing facility that can minimize the harmful gas generated from the fire extinguishing gas due to fire damage and high temperature and minimize the safety of human life.

Meanwhile, in the conventional container valve, as shown in FIG. 3, the container coupling hole 11 and the gas discharge hole 12 and the sealing nut coupling hole 13 coupled to the container 7 are interconnected in a 'T' shape. A body part 1 having a shape; The cutter pin 141 of the solenoid valve 14 is provided with a through hole 21 through which the opening and exit of the sealing nut coupler 13 of the body portion 1 with the packing 3 installed therein. Sealing nut 2 to be coupled; One end receives the support of the spring (4) in contact with the inner surface of the packing (3) is installed to be slidably movable in the body portion 1 to selectively open the inner opening of the gas outlet (12) A piston type furanza (5); Sealing protrusion 122 protruded to have a triangular shape inside the gas outlet 12 of the body portion 1 while being injection molded through the trifluoride resin and installed in the groove formed at one end of the furanza 5. ) And a sheet-like sheet 90 for maintaining airtightness so that the gas in the container is not discharged to the outside through the line contact.

By the way, in order to prevent the gas in the container from being discharged to the outside through the gas discharge port 12 of the body portion 1 in the above, the triangular shape inside the gas discharge port 12 of the body portion 1 The sealing protrusion 122 is formed to have a shape, and a disc-shaped sheet 90 injection-molded using a trifluoride resin is installed in the groove formed at one end of the furanza 5.

However, in this configuration, since the end of the sealing protrusion 122 has a sharp edge between the blade and the liver, the furanza 5 blocking the gas outlet 12 of the body portion 1 that is subjected to the strong elastic force of the spring 4. When the disc-shaped sheet 90 of one side and the sealing protrusion 122 have elapsed for a long time in a line contact state, a triangular wedge type by the sealing protrusion 122 on one side of the sheet 90 is formed. There is a problem that the one groove is formed naturally, the airtightness is lowered.

In addition, a fire occurs in the above state, and the solenoid valve 14 is operated by the halon fire fighting equipment control unit so that the cutter pin 141 changes the pressure in the body 1 due to the hole in the packing 3. (I.e., the pressure of the spring 4 provided between the packing 3 and the other side of the eggplant 5 and the gas pressure filled in the space portion therebetween is the outer circumferential surface and the seat 90 of the eggplant 5). ) Is much smaller than the gas pressure in the vessel 7 applied to one end of the vessel), and the egg 5 is momentarily turned to the sealing nut 2 side (that is, the gas in the vessel 7 is temporarily Since the slide is moved for 30 seconds or 10 seconds as a sufficient time to be released, the gas in the container 7 is sprayed through the injection nozzle 8 installed in the gas outlet 12 in an instant to extinguish the fire.

In this way, after the carbon dioxide gas in the container 7 is instantaneously released, the pressure in the container becomes much smaller than the elastic force of the spring 4, so that the furanza 5 is moved to the gas outlet 12 again. In the wedge-shaped groove already formed in the seat 90 of the furanza 5, the sealing protrusion 122 is not accurately fitted and there is a high possibility of being in line contact with one side of the seat 90 in a staggered state. When the packing 3 in the sealing nut 2 is replaced with a new one, when the gas is refilled in the container 7, the gas passes through the gap between the wedge-shaped groove of the seat 90 and the sealing protrusion 122. May leak.

Therefore, after the container valve is operated once due to the topic, the container valve itself must be replaced or replaced with a furan installed with a new sheet. There is a problem that the loss, in particular the reliability of the halon fire extinguishing system itself is deteriorated.

The present invention was devised to solve such a conventional problem, and even if a long time passes, no deformation occurs between the seat, the fixed plate, and the inner surface of the gas outlet so that gas leakage through the accurate sealing function can be completely prevented. In addition, it is possible to prevent the inconvenience and unnecessary economic loss caused by the replacement of these components by preventing the need for exchanging the sheets including the eggs after the halon fire extinguishing system is operated due to the fire. The present invention provides a container valve sealing device for a gas fire extinguisher that can greatly improve the reliability of the installation system itself.

An object of the present invention described above, the body portion is formed so that the container coupler coupled to the container and the gas outlet and the sealing nut coupler coupled to the injection nozzle has a shape interconnected in a 'T' shape; A sealing nut having a through hole through which the cutter pin of the solenoid valve can enter and exit, and a sealing nut coupled to the sealing nut coupler of the body portion in a state where a packing is installed; One end receives the support of the spring which is in contact with the inner surface of the packing and is slidably installed between the sealing nut coupler and the gas outlet of the body part, so that the gas outlet is normally blocked by the inner opening. A piston-type furanza which is perforated in the packing to move momentarily toward the sealing nut when the gas pressure between the furan and the packing and the elastic force of the spring are much smaller than the pressure in the container to open the gas outlet for a predetermined time; In the gas valve of the gas fire extinguisher comprising a hermetic holding means for keeping the gas in the container between the inner portion of the gas discharge port and one end of the egg evacuator so as not to be discharged to the outside,

The hermetic holding means is formed with a tapered surface inclined at an inner surface of the gas outlet of the body portion by a predetermined angle, and injection molded with trifluoride resin so that an outer circumferential surface has the same inclined surface as the tapered surface at one end of the piston-type furan. It is achieved by fixing the ring-shaped seat and the end plate having a 'T' shape with bolts so that the gas outlet taper surface of the body portion and the inclined surfaces of the seat and the 'T'-shaped fixing plate are kept airtight through mutual surface contact. can do.

Therefore, even after a long period of time with the installation of the Halon fire fighting system, there is no risk of deformation occurring between the seat and the fixed plate and the inner surface of the gas outlet, which are installed in the furanza in the container valve body. Not only can the gas leak be completely prevented, but even if the halon fire extinguishing system is operated due to the occurrence of a fire, the confidentiality is maintained even if the seat including the egg is not replaced. The economic loss can be prevented in advance, and in particular, the reliability of the halon fire extinguishing system itself can be greatly improved.

Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention in detail as follows.

Figure 1 shows a longitudinal cross-sectional view of the container valve in accordance with the present invention, Figure 2 shows a longitudinal cross-sectional view when the container valve in accordance with the present invention is operated, Figure 3 shows a partial exploded perspective view of the halon fire extinguisher. .

Accordingly, the gas outlet 12 and the sealing nut coupler 13 to which the container coupler 11 coupled to the container 7 and the injection nozzle 8 are coupled may have a shape interconnected in a 'T' shape. A molded body part 1; The solenoid valve 14 has a through hole 21 through which the cutter pin 141 can enter and exit, and inside the sealing nut coupler 13 of the body portion 1 with the packing 3 installed therein. Sealing nut 2 to be coupled; One end receives the support of the spring (4) in contact with the inner surface of the packing (3) and is installed so as to slide between the sealing nut coupling hole 13 and the gas outlet (12) of the body (1) Normally, the opening of the gas outlet 12 is blocked, and a hole is drilled in the packing 3 due to a fire, so that the gas pressure between the furanza 5 and the packing 3 and the elastic force of the spring 4 are prevented. A piston-type furanza 5 which is momentarily moved to the sealing nut 2 side when the pressure in the vessel 7 becomes very small to open the gas discharge port 12 for a predetermined time; The gas valve of the gas fire extinguisher comprising an airtight holding means (6) which keeps the gas in the container (7) from being discharged to the outside between the inner part of the gas outlet (12) and one end of the furanza (5). To

The airtight holding means (6) forms a tapered surface (121) inclined at an angle with an inner surface of the gas outlet (12) of the body portion (1), and an outer surface at one end of the piston-type furanza (5). The ring-shaped sheet 9 which is injection-molded with trifluoride resin so as to have inclined surfaces 91 and 102 inclined at the same angle as the tapered surface 121 and a fixed plate 10 having a 'T' shape in longitudinal section are formed. The gas outlet 12 of the body 1 and the tapered surface 121 of the body part 1 and the inclined surfaces 91 and 102 of the seat 9 and the 'T'-shaped fixing plate 10 are hermetically sealed by bolts 53. It is characterized in that it is maintained.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, among the components constituting the container valve of the gas fire extinguisher, the shape of the body portion 1, the packing 3, the sealing nut 2 and the spring 4 is the same as the conventional container valve, so detailed description thereof will be omitted. .

However, in the present invention, the gas in the container 7 is discharged to the outside between the inner part of the gas outlet 12 and one end of the furanza 5 while deforming a part of the piston-type furanza 5. Not to change the shape and configuration of the airtight holding means (6) to keep the airtight so as not to be described in detail with respect to the configuration and operation relationship for these.

In the above, a tapered surface 121 inclined at a predetermined angle is formed on the inner surface of the gas outlet 12 of the body portion 1, and one end of the piston-type furanza 5 is formed in one plane. The bolt fastening hole 52 is formed at the center point thereof, and injection molding is performed in trifluoride resin so that an outer circumferential surface thereof has the same inclined surfaces 91 and 102 as the tapered surface 121 at one end of the furanza having a shape cut in a plane. The ring-shaped sheet 9 (that is, the hole 91 is drilled in the center portion) and the cylindrical section 101 fitted in the hole 91 of the sheet 9 having the 'T' shape in the longitudinal section (that is, in the center portion). ) Is fixed to the fixing plate 10 is formed with a bolt (53).

Accordingly, the tapered surface 121 of the gas outlet 12 of the body portion 1 and the inclined surfaces 91 and 102 of the ring-shaped sheet 9 and the 'T'-shaped fixing plate 10 are in surface contact with each other.

On the other hand, in general, the gas pressure introduced into these spaces, including the elastic force of the spring (4) provided between the other groove 52 and the packing (3) of the piston-type furanza (5) is the furanza (5) Since the gas outlet 12 and the tapered surface 121 and ring-shaped seat 9 which are in surface contact with each other as shown in FIG. The airtightness is maintained between the inclined surfaces 91 and 102 of the 'T'-shaped fixing plate 10, and even after a long period of time, the gas outlet 12, the tapered surface 121, the ring-shaped sheet 9, and the' T'-shaped fixing plate 10 are provided. Since the inclined surfaces 91 and 102 are maintained as they are without being deformed as in the prior art, no gas leaks through them.

In this state, a fire is generated and the solenoid valve 14 is operated by the control unit of the halon fire fighting equipment, so that the cutter pin 141 makes a hole in the packing 3 so that the other end of the furanza 5 and the packing ( 3) The gas filled in the space between the discharged to the outside through the hole of the packing (3), the pressure of the spring (4) provided between the packing (3) and the other side of the furanza (5) is the furanza ( Since the outer peripheral surface of 5) becomes much smaller than the gas pressure in the container 7 applied to one end thereof, the furanza 5 is momentarily turned to the sealing nut 2 side for a predetermined time (i.e., 30 seconds or 10 seconds). As shown in FIG. 2, the gas in the container 7 is rapidly injected through the injection nozzle 8 installed in the gas outlet 12 to extinguish the fire.

In this way, after the carbon dioxide gas in the container 7 is instantaneously released, since the elastic force of the spring 4 becomes smaller than the pressure in the container, the furanza 5 moves to the gas outlet 12 again. Since the tapered surface 121 is formed at the inner side of the gas outlet 12, the inclined surfaces 91 and 102 of the ring-shaped sheet 9 and the 'T'-type fixing plate 10 fixed to one side of the furanza 5 are formed. Since it is fitted in a sliding manner along the tapered surface 121, the inclined surfaces 91 and 102 of the gas outlet 12 of the body portion 1, the tapered surface 121 and the ring-shaped sheet 9 and the 'T'-shaped fixing plate 10 ) Is in contact with each other again.

Therefore, when the halon fire extinguishing system is operated due to the occurrence of a fire, when the gas is to be refilled in the container 7, only the packing 3 in the container valve punched by the solenoid valve 14 is replaced with a new one. The sheet 9 or the fixing plate 10 including (5) does not need to be replaced, thereby preventing inconvenience and unnecessary economic loss due to the exchange of the furanza (5) or the sheet (9) and the fixing plate (10). Of course, it is possible to improve the reliability of the halon fire extinguishing system itself.

As described above, according to the present invention, a tapered surface that is inclined at a predetermined angle is formed on the inner side of the gas outlet of the container valve body portion, and an outer surface is inclined at the same angle as the tapered surface on one end of the piston-type furan. By installing a ring-shaped seat and a 'T'-shaped fixing plate so that the tapered surface of the gas outlet and the inclined surface of the sheet and the fixing plate are in contact with each other, the flannel in the container valve body even after a long period of time with the halon fire fighting system installed There is no fear of deformation occurring between the seat installed on the seat, the fixed plate and the inner side of the gas outlet, so that the gas leak can be completely prevented through the accurate sealing function. Even if you do not exchange seats, including the Hulanza, the confidentiality will remain the same. And the inconvenience and unnecessary economic losses according to the imposition of exchange can be prevented, it is very useful especially designed such that can significantly improve the reliability of halon fire extinguishing system itself.
