DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A system for detecting a toxic substance leakage according to the present invention is a system for detecting a toxic substance leaked from a pipeline, a tank, a valve, or a device used for storing, conveying or treating a harmful substance such as a flange, a socket or a sleeve used for connecting pipes or tanks or valves (J) formed in a facility, facility, or system, or a joint (J) formed in a facility or facility or system that joins a leaky joint (J) or joint (J) And includes a guide member (10) and a sensing member (20), which can quickly and accurately detect whether leakage of harmful substances such as gas, foam, And may further include at least one of an outflow space 30, an alarm member 40, a control unit (not shown), and a shutoff unit (not shown).

As shown in FIG. 2, the guide member 10 is installed along the periphery so that the joint J of any one of the piping, the tank, and the valve is closed. As shown in FIG. 3, And the flow of the toxic substances leaking through the joint portion J is guided and flowed on the flow path 11 without flowing out immediately. That is, as the density of the toxic substances increases, the periphery of the joint J in the inside of the guide member 10 leaks the harmful substances along the inner side of the guide member 10 relatively to the inner pressure or the density of the toxic substances, 10). Therefore, even if the toxic substance leaks out of the shaded area of the joint J, the sensing member 20 formed on the guide member 10 is widely discolored, so that the operator can know the leaking state of the toxic substance. In addition, the flow of the harmful substances leaked may be made to flow in a certain direction or smoothly by using the outflow space 30. In addition, the guide member 10 may be provided so that a plurality of joint portions J are sealed at one time. Since the circumference of the joint J of the pipe, the tank or the valve is generally circular, the guide member 10 is made of synthetic resin, rubber, silicone, plastic, or the like which can be bent along the circumference of the joint J, Vinyl, fiber, metal, Teflon, polypropylene, polyethylene, polyvinyl chloride, or a composite compound.

The guide member 10 may be formed in various shapes such as an arcuate shape as shown in FIG. 3 (a), a rectangular shape, a polygonal shape, or the like, have. When the guide member 10 is made of a material such as vinyl or the like whose shape is not uniform, the shape of the cross section of the guide member 10 may not be constant. Therefore, the guide member 10 may be hollow The shape can be changed so that it can be formed.

In addition, when the guide member 10 is installed in the valve, an opening (not shown) which can be opened for valve adjustment may be formed. For example, the guide member 10 can be closed with a valve, and the valve can be used through an opening that can be opened when adjustment of the valve is required.

8, the engaging member 12 is formed along the longitudinal direction on both sides of the guide member 10 and the engaging member 12 can be attached to the periphery of the joint J. The joining member 12 may be attached using an adhesive, an adhesive, or a tape. The engaging member 12 may be formed by extending the guide member 10 and may be formed continuously or at intervals along the longitudinal direction of the guide member 10 and may have various lengths and shapes, And may be made of a material or material different from that of the guide member 10. For example, rubber, elastic band, string, plastic band, fiber, metal, Teflon, polypropylene, polyethylene, polyvinyl chloride or synthetic resin may be used for the coupling member 12.

9, the guide member 10 or the coupling member 12 may be provided with a fixing member 14 so that the guide member 10 or the coupling member 12 is connected to the joint J of the pipe, Elastic band, string, plastic band, fiber, metal, Teflon, polypropylene, polyethylene, polyvinyl chloride, or synthetic resin may be used as the fixing member 14. This is because when the toxic substance leaks from the joint part J, the guide member 10 or the engaging member 12 is separated from the joint J and the leaked toxic substance is discharged to the outside of the guide member 10 The guide member 10 or the engaging member 12 may be detached from the joint portion 12 due to the leakage pressure of the harmful substance by using the fixing member 14. [ J of the guide member 10 or the engaging member 12 which is spaced apart from the joint J by the fixing force or the restoring force of the fixing member 14 even if the distance between the guide members 10, So that the leaked toxic substances flow along the inside of the guide member 10, so that the function of detecting and alarming the toxic substances can be performed more accurately. For example, in this situation, the leaked toxic substances can flow to the outflow space 30. The fixing member 14 may be used as the guide member 10 or the engaging member 12 or the engaging member 12 or the guide member 10 or the engaging member 12 And may be detachably or separately provided.

For example, the fixing member 14 can be used for the guide member 10 or the coupling member 12 as shown in Figs. 11C, 11D and 11E, and Fig. 11C and Fig. 11D show the fixing member 14, 11d and 11e are such that the fixing member 14 is not easily separated from the guide member 10 or the engaging member 12. In addition,

The fixing member 14 may be used for binding both ends of the guide member 10 or the coupling member 12 and may be as shown in Figs. 11F, 11G, and 11H, Both ends of the member 12 can be fixed with the fixing member 14 by engaging or overlapping each other. The lid 32 or the alarm member 40 may be utilized for binding both ends of the guide member 10 or the engagement member 12. For example, (40).

The fixing member 14 can be used only for a part of the guide member 10 or the engaging member 12 as shown in Figs. 11I and 11J, thereby reducing the cost required for the fixing member 14. Fig.

10 (a) and 10 (b), the joining member 12 may be engaged with the attachment member 15 after the attachment member 15 is attached to the periphery of the joint J. At this time, the attachment member 15 may be provided with an insertion space therein. At the same time, the fixing member 14 may be provided on the attachment member 15. A holder for supplementing the engaged state of the guide member 10 may be formed or coupled to the attachment member 15. For example, as shown in FIG. 10 (c), the attachment member 15 may be provided with an arch- May be formed or combined to fix the guide member 10.

In the case where the joining member 12 is attached to the periphery of the joining portion J, it takes a lot of time to perform the operation by using an adhesive, an adhesive, or a tape. The attachment member 15 is attached to the periphery of the joint J and then the engagement member 12 is inserted into or engaged with the inside of the attachment member 15 so that the operation is convenient and the operation time can be reduced have. The fixing member 14 may be used as the attachment member 15 or may be formed or joined to the attachment member 15 or may be separately provided and detachably attached to the attachment member 15. [ The attachment member 15 may be made of silicone, rubber, elastic band, cord, plastic band, fiber, metal, Teflon, polypropylene, polyethylene, polyvinyl chloride, synthetic resin or a Velcro tape having excellent bonding strength.

A sealing member (not shown) for allowing the engaging member 12 or the attaching member 15 to adhere to the periphery of the joint J is engaged with or attached to the engaging member 12 or the attaching member 15, The sealing force can be maintained at a high level even when the attachment surface around the joint J is uneven. For example, the contact member may be made of a material capable of increasing the sealing force such as silicone, rubber, adhesive, sealing tape, grease, paint, fiber, synthetic resin, glass, Teflon, polypropylene, polyethylene or polyvinyl chloride. Further, the contact member may be provided in a state of being attached to the coupling member 12 or the attachment member 15, or may be separately provided and used separately.

The plurality of guide members 10 installed at different positions can be connected to each other through a connection member (not shown) formed of a hollow tube tube or the like. When such a connection member is used, It is possible to reduce the number of members installed for detection and alarm.

4 (a), the sensing member 20 may be formed on the inner side of the guide member 10, and the sensing member 20 may be coated with the reagent that is discolored in response to the harmful substance, Or a tape or patch using reagents may be attached. Such tape or patch may be paper, fiber, synthetic resin, or compound compound. Thus, when the sensing member 20 is formed on the inner side of the guide member 10, it is possible to prevent the sensing member 20 from being contaminated from external dirt, liquid such as water or detergent. Accordingly, when the toxic substance leaks through the joint J, the toxic substance reacts with the reagent and is discolored, so that the leakage of the toxic substance is detected.

6, the sensing member 20 is coated with a reagent that is discolored in response to a harmful substance, or is attached to the guide member 10 or the joint J in the form of a tape in which such a reagent is used A synthetic resin or an elastic member is formed on both sides of the sensing member 20 so as to be easily installed and removed through the outlet space 30, . At this time, the replaceable sensing member 20 may be made of fiber, paper, plastic, vinyl, rubber, or various synthetic resins, which are painted, mixed, or doped with reagents which are discolored in response to harmful substances. In the case where the sensing member 20 is applied to the inside of the guide member 10 or attached in the form of a tape or a patch, if the reagent is expired and the reagent needs to be replaced, the entire guide member 10 is removed, If the sensing member 20 is installed separately from the guide member 10, the replacement operation is easy and the cost can be reduced. Here, when a harmful substance leaks and reacts with a reagent, the reagent changes to a color different from that before the harmful substance leaks. For example, there is a litmus paper in which the color changes depending on the acid and alkali acid base concentration.

Accordingly, as the toxic substances leaking from the joint J flow along the flow path 11 of the guide member 10, the color of the sensing member 20 located at the portion where the toxic substances pass is changed soon, J), the range of discoloration is wider than when only the reagent is applied to the joint (J) or only the tape or patch with the reagent is worn. Therefore, even if there is leakage of harmful substances, Leakage can be easily identified from the outside.

In addition, the guide member 10 may preferably be made of a material which can be seen from the outside or inside the guide member 10, and may be made of, for example, transparent or translucent material, It is possible to quickly and accurately detect the leakage of harmful substances.

At the same time, the guide member 10 is preferably made of a corrosion-resistant material, thereby preventing corrosion caused by toxic harmful substances.

In another embodiment of the present invention, the sensing member 20 is formed in the periphery of the outflow space 30, and when the toxic substance leaks through the joint J, it is discolored to sense the leakage of the toxic substance . By forming the sensing member 20 only in the periphery of the outflow space 30 without forming the sensing member 20 along the entire guide member 10, the cost required for the reagent sensing member can be reduced and replaced . At this time, when it is not necessary to observe the inside of the guide member 10, the material of the guide member 10 may be configured not to be transparent or translucent. In addition, the sensing member 20 may be attached to the periphery of the outflow space 30 in the form of a tape or patch in which a reagent is used, . In addition, the sensing member 20 may be in the form of a reagent coated on the inner side, a bag having a tape or a patch on which reagents are used, and an opening through which the toxic substance may flow out may be formed in the bag. A filter for filtering harmful substances may be installed or a neutralizer member may be installed.

3, at least one outlet space 30 is formed in the guide member 10, and the outlet space 30 is formed in a circular, elliptical, polygonal hole, As shown in FIG. 3 (d), the outlet space 30 may be formed in a shape that is pitched on at least one side of the guide member 10. [ 3 (e), the outflow space 30 may be formed by cutting off both ends of the guide member 10, or the outflow space 30 may be formed between the end portions of the plurality of guide members 10 . As shown in FIG. 3 (f), the outflow space 30 can be formed by a gap formed by the end portions of the guide member 10 being engaged or overlapped with each other, or the end portions of the plurality of guide members 10 being engaged or overlapped with each other . 3 (g), the sensing member 20 formed in the periphery of the outflow space 30 may be coated with a reagent on the inner side or may include a reagent-applied tape or a patch T attached thereto An opening (O) through which a harmful substance can flow out may be formed in the bag, and a filter for filtering harmful substances may be installed on the inside or a neutralizing member may be installed. At this time, the opening O may be formed so as to be opened when the inner pressure of the sealing bag is increased due to the harmful substances flowing out. Further, a cover which is opened when the inner pressure of the bag becomes high may be used on the opening (O).

The outflow space 30 may be formed in the form of a hole or a gap in the joining member 12, the attachment member 15 or the contact member (not shown) So that the pressure inside the guide member 10 is increased and opened. It is also possible to form a hole or a gap between any two or more of the guide member 10, the engaging member 12, the attaching member 15 or the contact member (not shown), and the surface of the attaching portion such as a pipe, The outlet space 30 may be formed and the outlet space 30 may be configured such that the pressure inside the guide member 10 is increased by the leakage of the toxic substances. In addition, the pressure inside the guide member 10 is increased by the leaked toxic substance, and the guide member 10, the engaging member 12, the attaching member 15 or the contact member (not shown) and the pipe, Any two or more of the surfaces of the same attachment portion may be opened to form the outflow space 30 in the form of a gap.

In addition, a lid 32 may be used around the outlet space 30 to prevent contaminants such as moisture or dust from entering the guide member 10 from the outside of the guide member 10. [

Since the guide member 10 is in close contact with the periphery of the joint J and is hermetically sealed so that harmful substances are leaked from the joint J to the inside of the guide member 10, The internal pressure of the guide member 10 is increased. At this time, the outflow space 30 reduces the internal pressure of the guide member 10 due to leakage of the toxic substance from the joint J, thereby smoothing the internal flow of the toxic substance.

In addition, since the fluid generally flows from a high pressure to a low pressure, the harmful substances leaked from the joint J are guided to flow toward the low-pressure discharge space 30, The color of the joint portion 20 changes soon so that the leakage of the harmful substance occurs in any part of the joint J so that the reagent is applied only to the joint J or the discoloration Since the range is wide, it covers the shaded area, and leakage of harmful substances can be easily confirmed from the outside. That is, the outflow space 30 can guide the leakage of toxic substances leaking from the inside of the guide member 10 at a specific position.

Therefore, it is possible to quickly and accurately detect the leakage of harmful substances, thereby eliminating the shaded area, and it is possible to prevent leakage of hazardous materials locally due to a simple structure and low-cost system.

4 (b) and 4 (c), the sensing member 20 is not formed on the inner side of the guide member 10 in the other embodiment of the present invention, but a pipe, a tank or a valve The guide member 10 may be provided so that the sensing member 20 is formed along the circumference of the joint J of the sensing member 20 and the joint J is sealed on the sensing member 20. [ At this time, the sensing member 20 is located below the guide member 10. [

In addition, engagement members 12 may be formed on both sides of the guide member 10 along the longitudinal direction thereof, and the engagement members 12 may be coupled to the upper side of the sensing member 20.

In addition, the sensing member 20 may be in the form of a coated or contained reagent that is discolored in response to a toxic substance, or may be attached in the form of a tape or patch using reagents, In case of leakage, harmful substance reacts with reagent and is discolored, so leakage of harmful substance is detected.

At this time, when the guide member 10 is made of a transparent or semitransparent material, the inside of the guide member 10 can be seen from the outside so that the discoloration state of the sensing member 20 can be easily recognized from the outside, can do.

5 (a), a filter 31 for filtering harmful substances is provided in a part of the outflow space 30, thereby preventing human accidents until the harmful substances are detected through the sensing member 20 . To this end, a neutralizer member for neutralizing harmful substances may be installed in the outlet space 30.

In addition, a lid 32 is openably and closably provided at a portion of the outflow space 30. The lid 32 normally closes the outflow space 30 to block the outflow of harmful substances, The inner pressure of the guide member 10 is automatically released through the outlet space 30 and the inner pressure of the guide member 10 is reduced, The internal flow of the material is smooth. The lid 32 may be a perforated structure or member that closes the outlet space 30 and is automatically opened by the pressure when the inner pressure of the guide member 10 is increased on the lid 32. Further, the filter 31 and the lid 32 may be used together or separately.

An alarm member 40 having a leakage sensor or a leakage sensor may be installed inside the guide member 10 or around the outlet space 30. [ Referring to FIG. 5 (b), an alarm member 40 for notifying the leakage of harmful substances may be installed in the periphery of the outflow space 30. For example, the alarm member 40 may be provided with a leakage detection sensor capable of detecting leakage of harmful substances. At this time, the alarm member 40 can be warned through sound or light. Further, the leak detection sensor may be located inside the guide member 10.

In addition, the shape of the alarm member 40 when the harmful substance flows out can be easily visible to the naked eye. In an embodiment, the alarm member 40 is formed of a material having a shape changing to swell and expand due to a leaked toxic substance and a sealed form, so that leakage of harmful substances can be easily recognized visually from the outside, An opening may be formed. Here, the alarm member 40 is made of a transparent or semitransparent material, and a reagent that is discolored in response to a harmful substance is applied or contained, or a tape or patch using reagents may be attached. In addition, when the alarm member 40 is puffed and expanded by using a specific color, a character, a symbol, a pattern, or a picture for alarming, the color or the character or the like becomes more visible, It is possible to visually confirm the leaking state of the harmful substance more easily.

In addition, referring to FIG. 7, when the harmful substance flows out through the outflow space 30, the alarm member 40 is configured such that the extended portion 41 folded by the pressure is unfolded, You can tell that a substance has leaked. In addition, the extension 41 may be formed of a specific color, a letter, a symbol, a pattern or a picture for alarming, for example, a red color. This has the advantage that it can be used for a longer period of time than the reagent.
