The sealing head 18 is a multi-diameter trapezoidal piece arranged according to the commonly used tee opening diameter, the thread diameter at the middle of the sealing head 18 will correspond to the opening diameter of the tee, and then the cylinder 17 is rotated to make the sealing head 18 rotate into the interior of the tee and seal the opening of the tee, and then gas is injected into the ventilation mechanism 101 through the detection mechanism 19 to increase the internal air pressure of the ventilation mechanism 101 and the tee, and then the inflation is stopped so that the gas content inside the tee and the inflation mechanism will no longer change due to external force, and then the air pressure is detected by the detection mechanism 19, and whether the air pressure is reduced is judged whether there is a leak at the connection between the tee and the sealing head 18, if the air pressure drops, there is a problem with the thread quality at a certain outlet of the tee, resulting in a decrease in sealing. Through the above structure, the device can perform airtightness detection on tees with various opening directions and opening sizes, thereby improving the practicability of the device and making it more convenient to detect the sealing of tees of various specifications and shapes.

[0024] like Figures 1 to 5As shown, the ventilation mechanism 101 includes a fixed cylinder 2; the fixed cylinder 2 is fixedly connected to the top of the mounting plate 1; the middle of the fixed cylinder 2 is slidably connected to a sliding column 21; the middle of the sliding column 21 is threadedly connected to a screw ring 22; the screw ring 22 is rotatably connected to the top of the fixed cylinder 2; the top of the sliding column 21 is fixedly connected to a connector 23; the middle of the connector 23 is fixedly connected to a vent pipe 24; the middle of the vent pipe 24 passes through the inside of the sliding column 21 and the vent pipe 24, and the other end of the vent pipe 24 is connected to the detection mechanism 19; when working, one opening of the tee is threadedly connected to the connector 23, and then The screw ring 22 is rotated and adjusted according to the diameter of the tee. As the screw ring 22 rotates, the sliding column 21 will rise or fall. By adjusting the height of the sliding column 21, the opening axis of the tee and the axis of the plugging head 18 are in the same plane, thereby facilitating the connection between the plugging head 18 and the tee. After the connection is completed, gas is pumped into the ventilation pipe 24 and the interior of the tee through the detection mechanism 19 for detection. Through the above structure, the height of the connecting head 23 can be adjusted so that the plugging head 18 can be more conveniently connected to the opening of the tee. At the same time, the applicability of the device to different tees is improved, so that the device can detect more types of tees.

[0025] like Figures 1 to 5 As shown, the side wall of the mounting frame 12 is fixedly connected with a fixing plate 3; the side wall of the fixing plate 3 is provided with a limiting groove 31; the side wall of the connecting head 23 is fixedly connected with a limiting plate 32; the limiting plate 32 and the limiting groove 31 are in sliding fit; during operation, as the connecting head 23 rises or falls, the limiting plate 32 will slide inside the limiting groove 31, and the limiting groove 31 will limit the limiting plate 32, so that the sliding column 21 will not rotate with the rotation of the screw ring 22, and at the same time the angle of the connecting head 23 is fixed, so as to facilitate the connection of the tee. Through the above structure, the occurrence of connection obstruction of the tee due to the rotation of the connecting head 23 can be reduced.

[0026] like Figures 1 to 3 As shown, a pair of slide rails 4 are fixedly connected to the middle of the fixed tube 16; a plurality of balls 41 are installed in the middle of the slide rail 4; the balls 41 are arranged between the cylinder 17 and the slide rail 4; during operation, as the cylinder 17 rotates, the cylinder 17 will generate sliding friction with the inside of the fixed tube 16, and through the arrangement of the slide rail 4 and the balls 41, the sliding friction between the cylinder 17 and the fixed tube 16 can be converted into rolling friction, thereby reducing the damage caused by friction between the cylinder 17 and the fixed tube 16.

[0027] like Figures 1 to 3As shown, the bottom of the slider 14 is connected to the extrusion plate 5 by bolts; the extrusion plate 5 is located at the bottom of the mounting frame 12; the top of the extrusion plate 5 is fixedly connected to a rubber pad 51; the rubber pad 51 is located between the mounting frame 12 and the extrusion plate 5; during operation, when a large batch of the same type of tees needs to be tested, the slider 14 is adjusted to a suitable position, and then the bolt in the middle of the extrusion plate 5 is rotated to reduce the distance between the extrusion plate 5 and the slider 14, thereby driving the rubber pad 51 to squeeze the mounting frame 12, so that a large friction force is generated between the rubber pad 51 and the mounting frame 12, so that the slider 14 will not easily slide in the middle of the slide groove 13, which is convenient for sealing detection of a large batch of the same type of tees.

[0028] like Figures 1 to 4 As shown, the end of the plugging head 18 is fixedly connected to a fixing rod 6; the end of the fixing rod 6 is fixedly connected to a plurality of brushes 61; during operation, when the plugging head 18 is inserted into the opening of the tee, the plugging head 18 is rotated to allow the plurality of brushes 61 to scrape the thread seams inside the tee opening, thereby cleaning impurities such as processing debris attached to the thread seams of the tee, thereby reducing the influence of the presence of impurities on the air tightness test results.

[0029] like Figure 4 As shown, the middle part of the fixing rod 6 is fixedly connected to the limiting ring 7; the diameter of the limiting ring 7 is smaller than the minimum diameter of the plugging head 18; during operation, when multiple brushes 61 enter the interior of some tees with smaller openings, the brushes 61 will be blocked by the end of the tee and bend toward the plugging head 18, and at this time, the middle parts of the multiple brushes 61 will be blocked by the limiting ring 7, so that the end of the brush 61 will not contact the end of the plugging head 18, thereby not entering the connection between the plugging head 18 and the tee to affect the connection of the tee.

[0030] During operation, one opening of the tee that needs to be inspected is connected to the ventilation mechanism 101, and then the pair of sliders 14 are moved and adjusted according to the positions of the other two openings of the tee, and then the pair of rotating blocks 15 are rotated to make the pair of plugging heads 18 face the opening of the tee, and then the cylinder 17 is slid to make the plugging head 18 contact with the opening of the tee. Since the plugging head 18 is a multi-diameter trapezoidal piece set according to the commonly used tee opening diameter, the thread diameter of a place in the middle of the plugging head 18 will correspond to the opening diameter of the tee, and then the cylinder 17 is rotated to make the plugging head 18 rotate into the interior of the tee and block the opening of the tee, and then gas is injected into the ventilation mechanism 101 through the detection mechanism 19 to make the ventilation mechanism 101 The internal air pressure of the tee increases, and then the inflation is stopped, so that the gas content inside the tee and the inflation mechanism no longer changes due to external force, and then the air pressure is detected by the detection mechanism 19, and whether the air pressure is reduced is judged whether there is a leak at the connection between the tee and the plugging head 18. If the air pressure drops, there is a problem with the quality of the thread at a certain outlet of the tee, resulting in a decrease in sealing. An opening of the tee is threadedly connected to the connecting head 23, and then the screw ring 22 is rotated and adjusted according to the diameter of the tee. As the screw ring 22 rotates, the sliding column 21 will rise or fall. By adjusting the height of the sliding column 21, the opening axis of the tee and the axis of the plugging head 18 are in the same plane, which is convenient for the plugging head. 18 is connected to the tee. After the connection is completed, the gas is pumped into the vent pipe 24 and the inside of the tee for detection through the detection mechanism 19. As the connector 23 rises or falls, the limit plate 32 will slide inside the limit groove 31, and the limit groove 31 will limit the limit plate 32, so that the sliding column 21 will not rotate with the rotation of the screw ring 22, and the angle of the connector 23 is fixed, which is convenient for connecting the tee. As the cylinder 17 rotates, the cylinder 17 will generate sliding friction with the inside of the fixed tube 16. Through the setting of the slide rail 4 and the ball 41, the sliding friction between the cylinder 17 and the fixed tube 16 can be converted into rolling friction. When a large batch of the same type of When testing the tee, adjust the slider 14 to a suitable position, and then rotate the bolt in the middle of the extrusion plate 5 to reduce the distance between the extrusion plate 5 and the slider 14, thereby driving the rubber pad 51 to squeeze the mounting frame 12, so that a greater friction force is generated between the rubber pad 51 and the mounting frame 12, so that the slider 14 will not easily slide in the middle of the slide groove 13, so as to facilitate the sealing inspection of large batches of tees of the same type. When the plugging head 18 is extended into the opening of the tee, the plugging head 18 is rotated to allow multiple brushes 61 to scrape the threaded seams inside the tee opening, and then clean up impurities such as processing debris attached to the threaded seams of the tee, thereby reducing the influence of the presence of impurities on the air tightness test results.
