Description

Technical Field

[0001] This utility model relates to the field of pipeline leak detection technology, and in particular to a pipeline leak detection device. Background Technology

[0002] Printing process.

[0003] A search revealed a Chinese patent publication number CN222718014U, which discloses a leak detection device for a heat transfer pipeline, relating to the field of heat pipeline leak detection technology. The device includes a switch valve, a heat pipeline body connected to one side of the switch valve, a fixing ring installed on the top of the heat pipeline body, a frustum-shaped insulation shell above the fixing ring, a guide groove on the top of the frustum-shaped insulation shell, an annular inner groove connected below the guide groove, a second spring fixedly connected inside the annular inner groove, an annular pressure plate fixed on the top of the second spring, a second rubber sealing ring above the annular pressure plate, a connector on the top of the frustum-shaped insulation shell, a hollow top rod fixed inside the connector, a guide block fixed on the outer wall of the connector, and a pressure gauge installed on the top of the connector.

[0004] This patent, by setting up a sealing installation mechanism, can install the seal inside the frustum-shaped thermal insulation shell, thereby achieving the effect of sealing and preventing leakage, thus further enhancing the sealing effect of the device. However, the rotation at a certain angle is somewhat ambiguous, and the operator cannot intuitively judge whether it has been rotated into place. In addition, the guide block may accidentally align with another guide groove, causing the locking to fail. Utility Model Content

[0027] Example 1

[0028] A pipeline leak detection device, such as Figures 1 to 4 As shown, the device includes a switch valve 2, a heat pipe body 1 connected to one side of the switch valve 2, a connecting pipe 3 fixedly connected to the side wall of the heat pipe body 1, a connector 5 connected to the top of the connecting pipe 3, a pressure gauge 4 installed at the top of the connector 5, three guide grooves 9 opened on the inner wall of the top of the connecting pipe 3, the three guide grooves 9 are arranged around the axis of the connecting pipe 3 at 120-degree intervals, a slot 10 opened on one side of the bottom of the guide groove 9, a receiving cavity opened at the top of the slot 10 away from the guide groove 9, a steel ball 12 slidingly fitted on the inner wall of the receiving cavity, a spring 11 fixed on the inner wall of the receiving cavity, the other end of the spring 11 connected to the steel ball 12, multiple locking blocks 15 fixed on the side wall of the connector 5, the locking blocks 15 slidingly fitted with the guide grooves 9 and the inner wall of the slot 10, and an arc-shaped groove opened on the top outer wall of the locking blocks 15 to limit the movement of the steel ball 12.

[0029] The inner wall of the connecting pipe 3 has a tapered cross section. A sealing block 6 is connected to the inner wall of the connecting pipe 3 by a spring 7. The sealing block 6 is sealed to the inner wall of the top of the connecting pipe 3. A hollow top rod 8 is fixed to the inner wall of the bottom end of the connecting head 5. An inclined surface inclined towards the axis of the connecting head 5 is provided on the side wall of the bottom end of the connecting head 5. A limit ring 13 is fixed to the inner wall of the connecting pipe 3. A sealing ring 14 is provided on the outer wall of the top of the limit ring 13. The inclined surface at the bottom end of the connecting head 5 is pressed to fit the sealing ring 14.

[0030] When connecting connector 5 and connecting pipe 3, align the locking block 15 with the guide groove 9. Insert the bottom end of connector 5 into connecting pipe 3, and the locking block 15 enters the guide groove 9. When the locking block 15 reaches the bottom of the guide groove 9, connector 5 cannot move down. At this time, rotate connector 5 to allow the locking block 15 to enter the slot 10. When the locking block 15 moves to one end of slot 10, it will first squeeze the steel ball 12, causing the steel ball 12 to move upward. The spring 11 is compressed and deformed. When the arc groove on the locking block 15 is aligned with the steel ball 12, the spring 11 pushes the steel ball 12 upward. As ball 12 moves downward, it enters the arc-shaped groove and impacts the inner wall of the groove, producing a distinct impact sound. This indicates that the locking block 15 has rotated into place. When connector 5 moves downward, the hollow top rod 8 presses the sealing block 6 downward, causing connector 5 to connect with the thermal pipe body 1 through the connecting pipe 3. At the same time, the inclined surface at the bottom of connector 5 presses the sealing ring 14 to seal the connection between connector 5 and connecting pipe 3. The inclined surface can distribute the compressive stress evenly, eliminate stress concentration at the edge, and reduce permanent deformation that occurs during long-term compression.

[0031] The device is equipped with a guide groove 9, a slot 10, a spring 11, a steel ball 12, and a locking block 15. When the locking block 15 rotates to one end of the slot 10, there is a clear audible feedback, which allows the operator to confirm that the device is installed correctly.

[0032] By setting the bottom end of connector 5 as a slope, the compressive stress is evenly distributed, stress edge concentration is eliminated, and permanent deformation that occurs during long-term extrusion is reduced.

[0033] Example 2

[0034] A pipeline leak detection device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 5 As shown, a toothed ring 16 is fixed to the outer wall of the top end of the connecting pipe 3, and a toothed ring 2 17 is vertically limited and slidably fitted to the outer wall of the bottom end of the connector 5. A spring 3 18 is fixed to the top end of the toothed ring 2 17, and the other end of the spring 3 18 is connected to the connector 5. The toothed ring 2 17 and the adjacent end of the toothed ring 16 are mutually engaged and limited.

[0035] When connector 5 is inserted into connector tube 3 and rotated, toothed ring 17 is pushed upward a certain distance to prevent toothed ring 17 from engaging with toothed ring 16. After connector 5 is rotated to the position, toothed ring 17 is released, and spring 3 18 pushes toothed ring 17 downward. Toothed ring 17 engages with toothed ring 16 and is limited to stop connector 5, preventing connector 5 from being displaced and reset due to vibration.

[0036] By incorporating toothed ring 16, toothed ring 2 17, and spring 3 18, the connector 5 can be limited to prevent displacement and reset due to vibration.

[0037] Working principle: When connecting the connector 5 and the connecting tube 3, push the toothed ring 17 upward a certain distance, then align the locking block 15 with the guide groove 9. Insert the bottom end of the connector 5 into the connecting tube 3, and the locking block 15 enters the guide groove 9. When the locking block 15 reaches the bottom of the guide groove 9, the connector 5 cannot move downward. At this time, rotate the connector 5 to let the locking block 15 enter the slot 10. When the locking block 15 moves to one end of the slot 10, it will first squeeze the steel ball 12, causing the steel ball 12 to move upward. The spring 11 is compressed and deformed. When the arc groove on the locking block 15 is aligned with the steel ball 12, the spring 11 pushes the steel ball 12 downward. The steel ball 12 enters the arc groove and is in contact with the inner wall of the arc groove. The impact produces a distinct impact sound, indicating that the locking block 15 has rotated to the correct position. The toothed ring 17 is released, and the spring 18 pushes the toothed ring 17 downwards. The toothed ring 17 engages with the toothed ring 16, limiting the connection head 5 and preventing it from shifting due to vibration. As the connection head 5 moves downwards, the hollow top rod 8 presses down on the sealing block 6, allowing the connection head 5 to connect to the heat pipe body 1 via the connecting pipe 3. Simultaneously, the inclined surface at the bottom of the connection head 5 presses down on the sealing ring 14, sealing the connection between the connection head 5 and the connecting pipe 3. The inclined surface ensures even distribution of the compressive stress, eliminating stress concentration at the edges and reducing permanent deformation during long-term compression.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
