1 is a cross-sectional view of a flame shield according to an embodiment of the present invention.

Referring to FIG. 1, the flame arrestor 10 includes a cover 11, a body 13, a pedestal 15, and an element assembly 20. The flame blocking device 10 passes a gas included in a tank (not shown) coupled with the body 13 to the outside of the flame blocking device 10 through the body 13. However, the flame blocking device 10 does not allow the flame generated from the outside of the flame blocking device 10 to pass through the body 13 into the flame blocking device 10. The cover 11 is for protecting the flame shield 11 from rain or bird droppings. According to an embodiment, the cover 11 may be referred to as a weather hood. In addition, when the flame occurs, the cover 11 is opened to serve to inform that the flame has occurred.

The pedestal 15 is mounted above the body 13 to support components such as the element assembly 20. There is one element assembly 20 shown in FIG. 1, but the number of element assemblies 20 actually positioned on the pedestal 15 is at least two. The larger the number of element assemblies 20, the faster the heat of the flame can be removed. This is because the flame is dispersed and extinguished.

FIG. 2 shows a plan view of the flame arrester shown in FIG. 1.

1 and 2, the plurality of element assemblies 20-1, 20-2, and 20-3 are distributed with respect to the center C 1 of the pedestal 15. The element assembly 20 shown in FIG. 1 represents any one of the plurality of element assemblies 20-1, 20-2, and 20-3 shown in FIG. 2. In FIG. 2, the number of element assemblies 20-1, 20-2, and 20-3 is three. However, in some embodiments, the number of element assemblies 20-1, 20-2, and 20-3 may vary. If the number of the plurality of element assemblies 20-1, 20-2, and 20-3 is two, the two element assemblies may be located facing each other. If the number of the plurality of element assemblies 20-1, 20-2, and 20-3 is nine, the nine element assemblies may be spaced apart at equal intervals from each other.

The central region CR including the center of the pedestal 15 is closed so that gas cannot pass through the central region CR. Also, the flame cannot be extinguished through the central region CR. Thus, the flame is dispersed and extinguished into the plurality of element assemblies 20-1, 20-2, and 20-3. The element assembly is not located in the central area CR. If the central region CR is not closed, a backfire phenomenon may occur in which heat of flame enters the body 13. If foreign matter is caught in the unsealed portion, the heat of the flame cannot be removed properly, and the heat of the flame can conduct into the body 13. The diameter of the central region CR is at least 2 cm and at least within the boundaries of each of the plurality of element assemblies 20-1, 20-2, and 20-3. That is, the central region CR does not overlap with the plurality of element assemblies 20-1, 20-2, and 20-3. In addition, the diameter of the central region CR is larger than the diameter of the inlet BI of the body 13. Thus, the gas flowing through the body 13 is dispersed without concentration. That is, since the diameter of the central region CR is larger than the diameter of the inlet BI of the body 13, the gas can be moved to the plurality of element assemblies 20-1, 20-2, and 20-3. have. In addition, the flame is not centrally concentrated and may be dispersed and dissipated into the plurality of element assemblies 20-1, 20-2, and 20-3. According to an embodiment, the size of the central area CR may vary.

3 is an enlarged cross-sectional view of the element assembly shown in FIG. 1.

1 to 3, the element assembly 20 includes an element ring 21, a first support 30, at least one or more elements 40, and 60, and a second support 50. ), And a third support 70.

Inside the element ring 21, a first support 30, at least one element 40, or 60, a second support 50, and a third support 70 are located, and the element ring 21 is It serves to fix the first support 30, at least one or more elements 40, or 60, the second support 50, and the third support 70.

Each of the first, second, and third supports 30, 50, and 70 is divided into an enclosed region 31, 51, or 71 and an open / close region 33, 53, or 72. The enclosed areas 31, 51, or 71 are made of metal, such as iron or aluminum, and cannot pass gas or flame. On the other hand, gas may pass through the opening / closing regions 33, 53, or 72.

At least one element 40, or 60 is stacked on the first support 30. In the present invention, the number of elements 40 and 60 is two, but the number of elements may vary according to embodiments. At least one of the elements 40, 60 has a through hole formed therein. Each of the elements 40, 60 includes a filter region 43, or 63 through which gas is passed, but the flame is extinguished, and a sealed region 41, or 61, through which the gas cannot pass and the flame is not extinguished. . The sealing region 41 or 61 is made of a metal material such as iron or aluminum. Reference numeral 42 denotes an enlarged region of the filter region 43 or 63. Each of the elements 40, 60 includes a sealed region 41, or 61, thereby dispersing the flame into the filter region 43, or 63. By spreading the flame instead of focusing it in one place, the flame can be quickly extinguished. In addition, the gas also prevents concentration of the gas flow rate due to the sealed region 41 or 61 and is dispersed into the filter region 43 or 63. If there is no enclosed area, the gas will be concentrated in the center, where the flame will not disperse and the flame's extinguishing function may be impaired.

4 shows a top view of the element shown in FIG. 3. In FIG. 4 the upper figure is a plan view of the element and the lower figure shows a sectional view of the element.

1 to 4, the size S1 of the sealed region 41 or 61 is larger than the size S2 of the filter region 43 or 63. In FIG. 4, the plan view of the second element 60 is illustrated, but the structure of the first element 40 is also the same as that of the second element 60.

1 and 3, a spring ring 23 is stacked on the third support 70. The cover 11 and the element assembly 20 are joined to each other by coupling means 29, 73, 75, 81, 85, 77, and 79. The second element 60 has a first through hole formed therein. The first bolt 29 is inserted into the first through hole. The first nut 73 is used to tighten the first bolt 29.

The fuse 75 has a second through hole therein so as to fit the exposed portion of the first bolt 29 exposed by engagement with the first nut 73. The fuse 75 is made of a polycarbonate material that can be melted by heat.

5 is an enlarged cross-sectional view of the fuse illustrated in FIG. 3.

1 to 5, the first diameter D1 is a bone diameter, the second diameter D2 is an effective diameter, and the third diameter D3 is an inner diameter. The thickness of the fuse 75 means 1/2 times the difference between the first diameter D1 and the second diameter D2. The thickness of the fuse 75 is between 4 mm and 9 mm. The following shows the separation time according to the thickness of the fuse by the experiment. The disconnection time means a time when the first bolt 29 and the second bolt 77 facing each other by the fuse 75 are separated when the fuse melts in the flame.

Separation time according to the thickness of the fuse Thickness of fuse Separation time availability 4mm or less Less than 53 seconds can not be used 4mm 53 seconds Available 4.5mm 1 minute 10 seconds Available 5 mm 1 minute 26 seconds Available 5.5mm 1 minute 55 seconds Available 6 mm 2 minutes 34 seconds Available 6.5mm 3 minutes 05 seconds Available 7 mm 3 minutes 41 seconds Available 7.5mm 4 minutes 12 seconds Available 8 mm 4 minutes 47 seconds Available 8.5mm 5 minutes 18 seconds Available 9 mm 6 minutes Available 9mm or more 6 minutes or more can not be used

If the thickness of the fuse 75 is less than 4 mm, the fuse 75 may be broken by the elastic force of the spring 83, and thus it may not be used. In addition, when the thickness of the fuse 75 is larger than 9 mm, the elastic force of the spring 83 is lost by heat, and the cover 11 cannot be opened by the elastic force of the spring. Therefore, it is impossible to use. Therefore, the thickness of the fuse 75 should be 4 ~ 9mm.

Referring to FIG. 1, a part of the second bolt 77 is inserted into the second through hole of the fuse 75. The remaining portion of the second bolt 77 except for the portion inserted into the second through hole is inserted into the third through hole formed in the first spring pad 81. The second spring pad 85 surrounds a portion of the first spring pad 81. The second bolt 77 is inserted through the fourth through hole of the cover 11 and is tightened by the second nut 79.

The spring 83 surrounds the outside of the coupling means 29, 73, 75, 81, 85, 77, and 79.

Referring to FIG. 1, the flame arrestor 10 includes a hinge 87 and a hinge post 89. Hinge 87 is installed on pedestal 15. Hinge 87 and pedestal 15 are coupled by engagement 91 of bolts and nuts. One side of the hinge post 89 engages with the hinge 87, and the other side of the hinge post 89 engages with the cover 11. The hinge post 89 and the cover 11 are joined by a nut 93. The prior art does not disclose the structure of the hinge and the hinge post as in the present invention. The prior art discloses two spring structures instead of hinges and hinge posts. That is, in the case of the prior art, the cover is opened by two spring structures. In the prior art, each fuse installed is melted and the cover is turned over by the elastic force of each spring. However, when foreign matter is inserted into one of the two springs and the spring does not operate properly, a problem arises in that the cover cannot be opened properly by the elastic force of only one spring. In order to solve this problem, the present invention proposes a hinge structure instead of two spring structures. In the case of including one spring instead of two spring structures, the probability of the foreign material being caught is lower than two, so the probability that the cover is not opened is low. When the cover 11 is opened by the spring 83 of the present invention, the hinge 87 and the hinge post 89 serves to well pass the cover 11.

Lug 95 is coupled using body 13 and bolt 97.

FIG. 6 is a cross-sectional view of a state of the flame blocking device before the cover shown in FIG. 1 and the flame blocking device after opening.

1, 2, and 6, when the fuse 75 is melted by a flame, the cover 11 is opened by the elastic force of the spring 83 and the hinge structures 87 and 89. Considering the thickness of the fuse 75, in order to open the cover 11 by the elastic force of the spring 83, the elastic force of the spring 83 must be at least 10 times the weight of the cover 11.

One end of the spring 83 is fixed to the body 13 by fixing means 84. Bolts 17 and nuts 19 may be used to secure to the body 13.

The fixing means 84 may be a wire of metal such as iron. The fastening means 84 prevents the spring 83 from falling out. On the other hand, the hinge 87 and the hinge post 89 do not have fixing means such as the fixing means 84.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
