if the value of the pressure gauge 4 remains stable within a specified time, the air tightness of the outer wall of the pipeline in the range of the detection area is qualified, then a detection person can buckle the other end of the L-shaped block 373, as the other end of the L-shaped block 373 extends between the air injection handle 36 and the inner side of the air injection frame 37, and the air injection spring 38 is arranged between the air injection handle 36 and the inner side of the air injection frame 37, the air injection spring 38 has a certain compression length, so the air injection handle 36 cannot touch the other end of the L-shaped block 373, the air injection handle 36 and the air injection frame 37 also provide protection for the other end of the L-shaped block 373, the error touch to the other end of the L-shaped block 373 is avoided, the L-shaped block 373 can slide in the L-shaped groove 371 under the condition that the detection person dials in the direction away from the detection sleeve 1, the L-shaped block 373 and the L-shaped groove 371 are in a sliding and sealing connection, no gas leakage is caused, as the L-shaped block 373 is toggled, one end of the L-shaped block 373 can pull the stay wire 374 in the movable hole 372, the stay wire 374 pulls the ball 141 to squeeze the spring 142, the ball 141 cannot touch the other end of the L-shaped block 373, the step hole 14 is smaller than the inner wall 14, the inner wall of the step hole 14 is also provided, the two inner side of the step hole 2 is also provided with a certain pressure release hole 2, and the pressure is communicated with the inner wall 2 of the pressure release chamber 2, and the pressure detection area 2 is connected with the pressure ring 2. Therefore, the annular bag 2 is shrunken under multiple acting forces such as extrusion force, tensile force, elastic force and the like, gas in the annular bag 2 can be discharged along the pressure relief inlet hole 16 and the step hole 14 and along the pressure relief outlet hole 15 in the process of shrunken annular bag 2, and the gas in the detection area can wash away impurities on the outer wall of the pipeline under the axial impact of the gas in the detection area towards the two end openings of the detection sleeve 1, so that the effect of attaching and sealing the annular bag 2 and the pipeline is prevented from being influenced by the impurities; because the elastic rope 23 can tighten the shrunken loop bag 2 close to the inner wall of the detection sleeve 1, contact abrasion between the loop bag 2 and the outer wall of the pipeline is avoided in the process that the detection sleeve 1 moves along the pipeline under the driving of the air injection frame 37, the loop bag 2 moves to the outer wall of the next pipeline under the perfect action of the loop bag 2, and the actions are repeated again to finish the air tightness detection process of the next pipeline; for some special-shaped condenser pipelines, such as a spiral or an s-shaped pipeline, a detector can still control the detection sleeve 1 to move along the outer wall of the pipeline, stay on the outer wall of the pipeline to be detected, and detect the air tightness of the outer wall of the pipeline; the application breaks through the traditional method that the to-be-detected condenser pipeline is moved to the detection equipment for detection, and only the portable detection device is required to be moved to be sleeved on the outer wall of the condenser pipeline to be detected;
in the embodiment, under the condition that the gas injection spring 38 drives the gas injection handle 36 to move to the limit position close to the detection sleeve 1, a gap is reserved between the gas injection handle 36 and the gas injection shell 31, so that the gas injection handle is prevented from being clamped to the hand of a detection person, and the design of the gas injection device is more reasonable;
according to the application, the detection sleeve 1 and the annular bags 2 expanded at two ends of the inner side of the detection sleeve 1 are matched, so that the air tightness detection of condenser pipelines with different specifications and shapes is realized, and meanwhile, the application has the characteristics of portability and flexibility.
Embodiment 2, this embodiment differs from embodiment 1 in that:
the two sides of the annular bag 2 in the axial direction of the detection sleeve 1 are provided with baffle rings 5; the outer wall of the baffle ring 5 is fixedly connected with the inner wall of the detection sleeve 1; the end face of the baffle ring 5 is perpendicular to the central shaft of the detection sleeve 1; the baffle ring 5 limits the two axial sides of the annular bag 2 in the expansion process, so that the annular bag 2 expands radially towards the detection sleeve 1.
In this embodiment, the inner wall of the baffle ring 5 is uniformly provided with an extension groove 51; the extending groove 51 is slidably connected with the extending block 52; the extending block 52 is connected with the bottom of the extending groove 51 through an extending spring 53; the extension block 52 is capable of radially limiting the barrier during inflation of the cuff 2 and of moving during movement of the detection sleeve 1 along the pipe.
In this embodiment, the extension block 52 is slidably and sealingly connected to the extension groove 51; the extending block 52 is communicated with the inner side of the annular bag 2 through a pressurizing air hole 54; the gas inside the annular bag 2 can enter the extension block 52 along the pressurizing air hole 54, and the extension block 52 is abutted against the outer wall of the pipeline under the dual actions of air pressure and elasticity.
The specific working procedure is as follows:
when the device is used, for some special-shaped pipelines, under the condition of non-straight pipelines, a certain gap is required to be kept between the detection sleeve 1 and the outer wall of the pipeline, but under the condition of overlarge gap between the detection sleeve 1 and the pipeline, the expanded annular bag 2 can expand axially towards the detection sleeve 1, so that the sealing effect between the inner sides of two ports of the detection sleeve 1 and the outer wall of the pipeline is affected;
therefore, in the case that the baffle rings 5 are arranged on two sides of the annular bag 2 in the axial direction of the detection sleeve 1, the baffle rings 5 can block the annular bag 2 in the expansion process, so that the annular bag 2 can be further sealed by the annular bag 2 only along the radial direction of the detection sleeve 1, and because the inner wall of the baffle rings 5 is provided with the extension grooves 51, the extension blocks 52 in the extension grooves 51 are abutted against the outer wall of the pipeline under the action of the extension springs 53, so that the gap between the baffle rings 5 and the outer wall of the pipeline is blocked by the extension blocks 52, the expanded annular bag 2 is further blocked, the annular bag 2 is radially expanded towards the detection platform under the double blocking of the extension blocks 52 and the baffle rings 5, the expansion effect of the annular bag 2 is improved, the gap between the inner sides of two ports of the detection sleeve 1 and the outer wall of the pipeline is further sealed by the annular bag 2, and the gas inside the extension grooves 51 and the annular bag 2 in the embodiment are communicated through the pressurizing air holes 54, so that the gas inside the annular bag 2 enters into the extension grooves 51 along the pressurizing air holes 54, the gas pressure inside the extension grooves 51 is further increased, the elastic blocks 52 are abutted against the outer wall of the pipeline under the action of the extension springs 53, and the expansion stability of the annular bag 2 is further improved in the axial direction; after the detection of the air tightness of the pipeline is finished, a detector controls the step hole 14 to be opened, so that the annular bag 2 is shrunken, gas in the detection area can be sprayed out through a gap formed between adjacent extension blocks 52, and the air flow area between the inner sides of two ports of the detection sleeve 1 and the outer wall of the pipeline is reduced by the action of the extension blocks 52, so that the gas in the detection area can be sprayed out quickly along the gap between the adjacent extension blocks 52, the cleaning effect on the outer walls of the pipeline on two sides of the detection sleeve 1 is improved, and the step hole 14 is opened to ensure that the pressure in the extension groove 51 is relieved;
then, a detection person controls the detection sleeve 1 to move along the outer wall of the pipeline, the detection sleeve 1 can drive the baffle rings 5, the extension blocks 52 and the ring bags 2 to move in the moving process, the ring bags 2 are tensioned and retracted between the inner sides of the two adjacent baffle rings 5 by the elastic ropes 23, so that the baffle rings 5 play a role in protecting the ring bags 2, the extension blocks 52 can abut against the outer wall of the pipeline under the action of the extension springs 53 and scrape the outer wall of the pipeline along with the movement of the detection sleeve 1, impurities on the outer wall of the pipeline are scraped away, the contact sealing effect of the ring bags 2 is avoided, under the condition that the detection sleeve 1 moves along the outer wall of the special-shaped pipeline, the outer wall of the special-shaped pipeline can squeeze the extension blocks 52, the extension blocks 52 are pressed to overcome the movement of the extension springs 53 towards the bottoms of the extension grooves 51, and the extension springs 53 can also give a reaction force to the extension blocks 52, so that the extension blocks 52 are abutted against the outer surface of the pipeline by the extension springs 53.
