DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a toxic gas and a liquid detection band and a method of manufacturing the same according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Throughout the specification, when an element is referred to as "including " an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 to 5, the toxic gas and the liquid detection band 1 (hereinafter, referred to as a 'detection band') are connected to the piping A bonding portion 13 which is fixedly coupled to an upper surface of the detecting portion 11 to be adhered to the pipe and a fixing portion 11 which is fixed to the fixing portion 11, And a cover part (15) which is interposed between the adhesive part (13) and blocks the external exposure of the detection part (11). As shown in FIG. 1, the transfer lines such as waste gas, waste water and the like are formed by connecting pipes of various shapes, and a sealing member of a pipe or a pipe is formed by heat or chemical substances emitted from waste gas, waste water, There arises a problem that gas or liquid leaks from the joint portion P of the pipe due to the tightening state of the pipe or the like. If a toxic gas or liquid leaks, there is a high risk that the equipment will be seriously damaged due to toxic substances as well as equipment damage, environmental pollution, and further, toxic substances are likely to spread to surroundings. Therefore, it is necessary to quickly identify the leakage of toxic gases or liquids, and to prevent the spread of toxic substances, thereby minimizing the damage caused by toxic substances. For this purpose, a cover device, which is formed in a cover shape to cover the joint portion of the pipe, has been developed to detect the outflow of gas and the like, as described in the related art, but it is difficult to separate the pipe joint from other pipe joints And it is not universal. Accordingly, in the present invention, it is formed in a band shape so that it can be easily attached regardless of the shape of the pipe joint portion P as shown in FIG. 2 and can be attached to the pipe joint portion P, It can be accurately detected, and the diffusion of the gas or liquid that is leaked can be prevented, and the damage caused by toxic substances can be minimized.

The detecting unit 11 is fixed to the lower surface of the adhering unit 13 and is attached to the pipe joint P to detect whether gas or liquid leaks. , For example, litmus solution, phenolphthalein, and methyl orange are immersed so as to detect the leakage of gas or liquid. Accordingly, the color of the detection unit 11 is changed according to the pH of the gas or liquid leaking through the pipe joint portion P, so that the component of the gas or liquid that leaks can be known. The adhesive portion 13 formed on the upper surface of the detecting portion 11 to closely contact the detecting portion 11 with the pipe joint portion P is formed of transparent synthetic resin to promptly check the color of the detecting portion 11 And an indicator portion 17 is formed on one side of the upper surface of the adhesive portion 13 so that it is easy to know whether the color of the detection portion 11 is a pH at which the color changes. Further, the detecting unit 11 may be formed of a porous ceramic material having enhanced heat resistance, and preferably, it may be formed of a silica raw material. Silica fabric is made of SiO2 raw material and can withstand temperatures of over 1000 ℃. It has very strong chemical resistance and does not react with various chemicals. It has porosity and trapping ability. When the indicator is soaked, It is possible to increase the concentration ability. Therefore, even in a high temperature gas or liquid leaking environment, it does not ignite or deform, it does not react with toxic substances, and the indicator can be stably fixed, so that it is possible to accurately detect a gas or liquid that leaks under any circumstances. The detecting unit 11 is fixedly coupled to the bottom surface of the adhering unit 13 so as to be in tight contact with the pipe joint P. The opposite side of the detecting unit 11 covers the adhering unit 13 So that the detection unit 11 is prevented from being exposed to the outside before use. In the above description, the detection of the pH of a gas or a liquid component has been described as an example. However, it is also possible to detect the presence or the content of other components by changing the reagent immersed in the detection unit 11.

The detection unit 11 is fixedly coupled to one side of the lower surface of the adhesive unit 13 and is fixed to a pipe joint to fix the detection unit 11 to the pipe joint P. To this end, the adhesive portion 13 is made of transparent synthetic resin so that adhesive can be adhered to the bottom surface and adhered to the pipe, so that the color of the detection portion 11, which is discolored, can be recognized immediately. Therefore, the operator can quickly grasp the components of the liquid or gas that is leaked, and can promptly take measures accordingly. The adhesive portion 13 is attached to the pipe in such a manner as to cover the detecting portion 11 from above the detecting portion 11 so that the gas or liquid leaking from the joint portion P of the pipe is not diffused to the outside . The adhesive portion 13 may be formed of a transparent synthetic resin, and transparent urethane excellent in waterproof effect is preferably applied. At one side edge of the adhering portion 13, the indicator portion 17 is formed to make it easy to see the component of the liquid or gas leaking according to the color of the detecting portion 11 which is discolored. The adhesive portion 13 is bonded to the cover portion 15 to prevent the detection portion 11 from being exposed to the outside before use of the detection band 1 according to the present invention.

The cover part 15 is bonded to the adhesive part 13 with the detection part 11 interposed therebetween to prevent the detection part 11 from being exposed to the outside, And may be formed of the same transparent synthetic resin as that of the adhesive portion 13. However, the present invention is not limited thereto, and it may be formed of various materials easily detachable from the adhesive portion 13. The cover part 15 prevents exposure of the detection part 11 to the outside of the detection part 11 before use of the detection band 1 to prevent the detection part 11 from being discolored in advance due to reaction with external substances, The cover portion 15 is removed and the detecting portion 11 is brought into close contact with the joint portion P of the pipe so that the adhesive portion 13 is attached to the pipe. At this time, as shown in FIG. 5, the cover part 15 may not be adhered to one side edge of the adhesive part 13, so that the cover part 15 can be easily removed.

The index portion 17 is formed at one side edge of the adhesive portion 13 so that the change of the color of the detection portion 11 by pH can be known. As shown in FIG. 4, And the color which can be discolored according to the pH of the gas or liquid to be measured is indicated by pH. Accordingly, the operator can easily recognize the gas or liquid component leaking by comparing the hue of the detecting unit 11 with the hue of the land surface 17. The indicator portion 17 is preferably formed on the upper surface of the adhesive portion 13 so that the indicator portion 17 can be easily seen by an operator.

6 to 7, the detection band 1 'according to another embodiment of the present invention is compared with the detection band 1 described with reference to Figs. 1 to 5 And the configuration of the adhesive section 13, the cover section 15 and the surface section 17 is the same as that of the detection band 1. Therefore, detailed description is omitted here .

The detection unit 11 of the detection band 1 'includes a lateral row detection member 111 and a longitudinal row detection member 113. The detecting unit 11 is formed such that a lateral detecting member 111 and a longitudinal detecting member 113 having the same size are spaced apart from each other by a predetermined distance and the lateral detecting member 111 Refers to a detecting unit 11 formed at a predetermined interval in the lateral direction and the longitudinal detecting unit 113 refers to a detecting unit 11 formed at a predetermined interval in the longitudinal direction. Therefore, as shown in FIG. 6, the lateral row detecting member 111 and the longitudinal row detecting member 113, which are smaller in size than the detecting unit 11 according to the embodiment, are spaced apart from each other by a predetermined distance in the lateral direction and the longitudinal direction, . Therefore, the elasticity or fluidity of the detection band 1 'itself is reduced by the adhesive portion 13 formed between the lateral row detection member 111 and the longitudinal row detection member 113 and having a certain degree of elasticity, So that the detection unit 11 can be fixed to the pipe joint P in a variety of shapes of the pipe joint P. The lateral row detecting member 111 and the longitudinal row detecting member 113 are attached at a plurality of positions of the pipe joint P so that the lateral row detecting member 111 and the longitudinal row detecting member 113, So that the position where the gas or liquid leaks can be more accurately known.
