Description

Technical Field

[0001] This utility model belongs to the field of detection equipment technology, and in particular relates to a leak detection device for fluoroplastic heat exchangers. Background Technology

[0002] Fluoroplastic heat exchangers are heat exchangers that use small-diameter fluoroplastic hoses as heat transfer components. They are particularly suitable for industries such as chemical, aerospace, and steel pickling due to their excellent corrosion resistance, enabling stable operation in strong acid and alkali environments. Fluoroplastic heat exchangers require regular leak testing during use, typically using specialized leak detection devices.

[0003] For example, Chinese utility model patent with announcement number CN221123744U discloses a condenser heat exchange tube leak detection device. When using this device, the sealing plate is connected and fixed to the heat exchange tube with bolts to ensure a seal.

[0004] However, the device requires a large number of bolts, making the process of connecting and fixing the detection device to the heat exchange tubes cumbersome, thus increasing the time spent on maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a leak detection device for fluoroplastic heat exchangers. This leak detection device improves maintenance efficiency by shortening the connection time between the device and the heat exchange tubes.

[0006] The technical solution adopted by this utility model to solve the above problems is: a fluoroplastic heat exchanger leakage detection device, comprising:

[0007] The heat exchanger pipe has a detection pipe at its inlet, a pressure gauge is fixedly connected to the detection pipe, and a connection component is also provided on the detection pipe.

[0008] The connecting assembly includes a bracket fixedly connected to the detection pipe, a lead screw rotatably connected to the bracket, a ring connected to the external thread of the lead screw, a clamping block movably connected to the bracket, a connecting rod horizontally fixedly connected between the clamping block and the ring, a fixed arc ring fixedly connected to the clamping block, and a movable arc ring hinged to the side of the clamping block via a hinge.

[0009] A further preferred technical solution is that a knob is coaxially fixedly connected to the end of the lead screw.

[0010] A further preferred technical solution is that a guide rod is horizontally fixedly connected to the bracket, and the guide rod is slidably connected to the ring.

[0011] A further preferred technical solution is that: the clamping block is fixedly connected to a limiting slider, and the bracket is provided with a limiting groove and the limiting groove is slidably connected to the limiting slider.

[0012] A further preferred technical solution is that: a connector is fixedly connected to the end of the movable arc ring, and screw holes are provided on the connector and one side of the upper clamping block, and the internal threads of the two sets of screw holes are connected to the same fixing bolt.

[0013] A further preferred technical solution is that the side of the clamping block is provided with an anti-slip pad.

[0014] A further preferred technical solution is that a sealing gasket is fixedly connected to one side of the detection pipe.

[0015] A further preferred technical solution is that the fixed arc ring and the movable arc ring form a circular ring, and the inner diameter of the circular ring is larger than the outer diameter of the heat exchanger pipe.

[0016] A further preferred technical solution is that protective pads are fixedly connected to the inner surfaces of both the fixed arc ring and the movable arc ring.

[0017] A further preferred technical solution is that the connecting rod is slidably connected to the bracket.

[0018] In summary, this utility model has the following advantages:

[0019] 1. This utility model uses clamping blocks to fit the connecting assembly onto the outside of the heat exchanger pipe. By flipping the movable arc ring upwards and connecting it to the upper clamping block with fixing bolts, the detection device and the heat exchanger pipe can be quickly connected. By rotating the screw, the ring moves away from the heat exchanger pipe. Under the sliding cooperation between the limiting groove and the limiting slider, the ring can move two sets of clamping blocks connected and fixed to it by connecting rods towards the detection pipe. This clamps and fixes the flange at the end of the heat exchanger pipe and the flange at the end of the detection pipe together, thus realizing the rapid connection between the detection device and the heat exchanger pipe. The operation is simple and effectively improves the detection efficiency.

[0020] 2. When the two sets of clamping blocks clamp and fix the flange at the end of the heat exchanger pipe and the flange at the end of the testing pipe, the fixed arc ring and the movable arc ring can form annular compression, thereby ensuring the connection and fixing effect between the two. Furthermore, when clamping and fixing the flange at the end of the heat exchanger pipe and the flange at the end of the testing pipe, the sealing gasket can also be compressed, thereby ensuring the sealing effect when the two are connected and fixed, and thus improving the accuracy of the test.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example

[0028] Please combine Figure 1-4 This embodiment of a fluoroplastic heat exchanger leakage detection device includes a heat exchanger pipe 1, a detection pipe 2 at the end of the pipe opening of the heat exchanger pipe 1, the detection pipe 2 having a structure design with one end open and the other end closed, a pressure gauge 3 fixedly connected to the detection pipe 2, a connecting component also provided on the detection pipe 2, and a sealing gasket 11 fixedly connected to one side of the detection pipe 2, which can ensure the sealing performance after the heat exchanger pipe 1 and the detection pipe 2 are connected.

[0029] The connecting assembly includes two sets of brackets 101 symmetrically fixedly connected to the detection pipe 2. A lead screw 102 is rotatably connected to the upper bracket 101, and a knob 4 is coaxially fixedly connected to the end of the lead screw 102 to facilitate rotation of the lead screw 102. A ring 103 is threaded onto the external of the lead screw 102. A clamping block 104 is movably connected to the bracket 101. A connecting rod 105 is horizontally fixedly connected between the clamping block 104 and the ring 103. The connecting rod 105 is slidably connected to the bracket 101 on the same side. A fixed arc ring 106 is fixedly connected between the two sets of clamping blocks 104. A movable arc ring 107 is hinged to one side of the lower clamping block 104 via a hinge. A guide rod 5 is horizontally fixedly connected to the lower bracket 101, and the guide rod 5 is slidably connected to the ring 103, which can guide the horizontal movement of the ring 103. The top of the upper clamping block 104 and the bottom of the lower clamping block 104 are both fixedly connected to... With the limit slider 6 connected, the two sets of brackets 101 are provided with limit grooves 7 at the positions corresponding to the limit slider 6, and the limit grooves 7 are slidably connected to the limit slider 6, which can play a certain guiding role for the horizontal movement of the clamping block 104. The end of the movable arc ring 107 is fixedly connected with a connector 8. The connector 8 and one side of the upper clamping block 104 are provided with screw holes 9. The internal threads of the two sets of screw holes 9 are connected to the same fixing bolt 10, which facilitates the fixing and loosening of the movable arc ring 107. One side of the two sets of clamping blocks 104 is provided with anti-slip pads, which can increase the contact friction between the clamping block 104 and the flange at the end of the heat exchanger pipe 1, thereby ensuring the clamping and fixing effect. The fixed arc ring 106 and the movable arc ring 107 can form a complete circular ring. The inner diameter of the circular ring is larger than the diameter of the heat exchanger pipe 1, which can smoothly fit the connecting component on the outside of the heat exchanger pipe 1.

[0030] The implementation principle of the fluoroplastic heat exchanger leakage detection device in this embodiment is as follows: First, the connecting component is sleeved on the outside of the heat exchanger pipe 1 through the opening between the two sets of clamping blocks 104. Then, the movable arc ring 107 is flipped upward and the connecting piece 8 is connected and fixed to the upper clamping block 104 with the fixing bolt 10. In this way, the detection device can be quickly connected to the heat exchanger pipe 1. Then, the detection pipe 2 is connected to the heat exchanger pipe 1, and the ring 103 is moved away from the heat exchanger pipe 1 by rotating the screw 102. Under the sliding cooperation between the limiting slide groove 7 and the limiting slider 6, the ring 103 can drive the two sets of clamping blocks 104, which are connected and fixed to it by the connecting rod 105, to move closer to the detection pipe 2. This clamps and fixes the flange at the end of the heat exchanger pipe 1 and the flange at the end of the detection pipe 2 together, thereby realizing the quick connection between the detection device and the heat exchanger pipe 1. The device is simple to operate, highly practical, and effectively improves testing efficiency. Simultaneously, when the two sets of clamping blocks 104 clamp and fix the flange at the end of the heat exchanger pipe 1 and the flange at the end of the testing pipe 2, the fixed arc ring 106 and the movable arc ring 107 can form annular compression, thus ensuring the connection and fixation effect between the two. Furthermore, when clamping and fixing the flange at the end of the heat exchanger pipe 1 and the flange at the end of the testing pipe 2, the sealing gasket 11 can also be compressed, thus ensuring the sealing effect when the two are connected and fixed, thereby improving the accuracy of the test. Then, pressurized air is supplied to the inside of the heat exchanger pipe 1 through an external air pump. At this time, the change in the value on the pressure gauge 3 is observed. If the value is constant, it indicates that there is no leakage in the heat exchanger pipe 1. If the pointer on the pressure gauge 3 swings back and forth, it indicates that there is a leakage in the heat exchanger pipe 1. Finally, after the test is completed, the testing device can be separated from the heat exchanger pipe 1.

[0031] Furthermore, a further improvement is that protective pads 12 are fixedly connected to the inner surfaces of both the fixed arc ring 106 and the movable arc ring 107, which can protect the heat exchanger pipe 1.

The drawings are presented in a simplified form and are not drawn to scale.
