(S110); A pressing adapter connection step (S120) of contacting the pressure adapter with the end surface of the extension portion of the inlet and then welding the inner or outer edge of the extension portion to the periphery (S120); Inserting a blocking film having an inner diameter size of the extension portion of the outlet or covering the outlet with a blocking film larger than the outer diameter of the outlet, and welding the periphery of the end of the extension of the outlet in contact with the blocking film (S130); A sealing test step (S140) comprising pressing the flow path through the pressing adapter; And after the sealing test step, cutting and cutting the extended extension (S150).

The sealing inspection method of a structure including a flow path therein according to an exemplary embodiment of the present invention can be applied to a straight flow path without a bent or branched area and a T-shaped flow path having a bent or branched area.

Seal inspection in a straight flow path

2A to 2E are perspective views illustrating an implementation of each step of FIG. 1.

Figure 2a shows the state of the step S110. One side of the flow path 110 forms an inlet 111, the opposite side of the inlet 111 of the flow path 110 forms an outlet 112, and each of the inlet 111 and the outlet 112 has a flow path 110 Extensions 121 and 122 are provided that extend in the longitudinal direction more than the length of the predetermined standard. For example, a first extension part 121 may be provided at the inlet 111 side, and a second extension part 122 may be provided at the outlet 112 side. The first extension part 121 and the second extension part 122 are the connection points of the inlet 111 and the outlet 112 when an independent tube is connected to the inlet 111 and the outlet 112 of the flow path 110 Since it can be easily broken, it is preferable to be formed integrally with the inlet 111 and the outlet 112 of the flow path 110.

Figure 2b shows the state of the step S120. In order to connect the pressurizing adapter, first, the pressurizing adapter 130 is prepared, for example, the pressurizing adapter 130 is a first flange portion provided at one end of the fluid transfer pipe 131 and the fluid transfer pipe 131 (132) may be included. Subsequently, the pressure adapter 130 is connected to the first extension part 121 of the inlet 111, wherein the end surface of the fluid transfer pipe 131 of the pressure adapter 130 is the first extension part. After contacting the end surface of (121), the inner or outer end circumference of the first extension part 121 is welded. For example, as shown in FIG. 2B, the circumference of the inner end of the first extension 121 may be welded.

Figure 2c shows the state of the step S130. To seal the outlet side, a blocking film 140 is first prepared. The blocking film 140 has an inner diameter size of the second extension part 122 of the outlet 112 or larger than the outer diameter of the second extension part 122. It can have a diameter. For example, the blocking layer 140 may be provided to have a diameter larger than the outer diameter of the second extension part 122. The blocking film 140 having a diameter larger than the outer diameter of the second extension part 122 covers the end of the second extension part 122 to cover the outlet 112, and the second of the outlet 112 in contact with the blocking film 140 The blocking film 140 is fixed by welding the periphery of the end of the extension 122, that is, by welding the periphery of the end of the second extension 122 from the outside of the second extension 122.

2D shows the state of step 140. For the sealing test, the flow path is pressurized through the pressurizing adapter 130, in which a high-pressure fluid is injected into the flow path to pressurize the flow path. To this end, the first flange portion 132 of the pressurizing adapter 130 is connected to a pipe of a device for supplying a high-pressure fluid in a flange connection method, so that the high-pressure fluid is passed through the pressurizing adapter 130 to the flow path 110 ) Can be injected inside. In this way, when a high-pressure fluid is supplied to the inside of the flow path 110, that is, from the inlet 111 to the outlet 112, the high-pressure fluid is fixed to the second extension part 122 of the outlet 112. The blocking film 140 is pressed, and at this time, the sealing test is performed by detecting whether there is leakage of fluid around the end of the second extension part 122 of the outlet 112.

2E shows the state of step 150. After the sealing test is completed, the first extension portion 121 of the inlet 111 and the second extension portion 122 of the outlet 112 are cut and cut from the inlet 111 and the outlet 112 of the flow path 110. Is removed. At this time, since only the first and second extensions 121 and 122 that are longer than the entire length of the flow path 110 are cut and removed, the overall specifications of the flow path 110 are maintained.

In addition, the circular frame 2123 includes a third extension 221 extending in the center direction of the circular frame 2123, and the second opening 2122 is a fourth extension equal to the diameter of the second opening 2122 It may include a part 222. The sealing step (S130) on the outlet side of the flow path 210 proceeds as described below, which will be described with reference to FIG. 3.

Since the inlet 211 side of the T-shaped flow path is the same as the pressure adapter connection step S120 described with reference to FIG. 2A in the description of the sealing inspection process in the linear flow path described above, a detailed description will be omitted.

Referring to FIG. 3B, first, a first blocking film 231 is inserted from the second opening 2122 in the direction of the first opening 2121 to cover the inner surface of the circumferential part 2123, and the first blocking film 231 And the circumference of the end of the third extension portion 221 of the phantom portion 2123 is welded. That is, the periphery of the inner end of the inner surface of the third extension part 221 of the phantom part 2123 in contact with the first blocking film 231 is welded.

The screw may pass through the center hole of the reinforcing plate 240 and the circular frame portion 2123 to be coupled to the first blocking film 231. In the process of (c), when the first opening 2121 is sealed only with the first blocking film 231, when a high pressure pressure is injected into the inside of the flow path 210, the circumferential part 2123 is convex due to the high pressure. Since deformation of the same circumferential portion 2123 may occur, the reinforcing plate 240 may be coupled to prevent this.

Meanwhile, the first blocking layer 231 shown in FIGS. 3A to 3D may have a relief structure 2311 that can be fitted into a center hole of the third extension portion 221 of the phantom portion 2123. In this case, as the embossed structure 2311 is fitted into the center hole of the third extension part 221 of the phantom part 2123, the first blocking film 231 may be more securely coupled and more tightly sealed. When the embossed structure 2311 is fitted into the center hole of the third extension part 221 of the phantom part 2123, the end circumference of the third extension part 221 of the phantom part 2123 in contact with the embossed structure is welded. 1 The blocking layer 231 may be fixed.

After sealing the outlet 212 in this way, when a high-pressure fluid is supplied from the inlet 211 communicating with the outlet 212 in the direction of the outlet 212, the high-pressure fluid is discharged from the first blocking film 231 of the outlet 212 and The second blocking film 232 is pressurized, and at this time, the sealing test is performed by detecting whether there is leakage of fluid from the first opening 2121 and the second opening 2122 of the outlet 212.
