Abstract
Description

[0002] In chemical production processes, pipeline systems play a crucial role in transporting various corrosive, flammable, explosive, or high-temperature and high-pressure media. The connections between pipelines are not only nodes in the fluid flow path but also core components affecting the safety and efficiency of the entire system. A significant proportion of leakage accidents in chemical plants occur at pipeline connections.
[0003] Currently, the most widely used connection method in chemical pipelines is flange connection. Flange connection is achieved by welding flanges to the two pipe ends, clamping gaskets between them, and then tightening multiple bolts diagonally.
[0004] While this technical solution is mature and reliable and can withstand high pressure and temperature, it has obvious limitations in practical applications: First, disassembly and assembly are cumbersome. When the equipment needs frequent cleaning, maintenance or replacement, operators need to disassemble and assemble multiple bolts one by one, which is time-consuming and laborious, resulting in long downtime and affecting production efficiency. Second, the installation quality depends on the operator's experience. If the bolt preload is uneven or the operating space is limited, it can easily lead to uneven compression of the gasket, creating a potential leakage hazard.
[0005] Based on this, the present invention designs a quick-release sealing chemical pipeline joint device to solve the above problems. Summary of the Invention

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example 1 Please refer to the accompanying drawings. This invention provides a technical solution: A quick-release sealing chemical pipeline connector device is used to connect a first pipeline 100 and a second pipeline 200, such as... Figure 1 As shown, it includes: The first pipe end boss 101 is an annular structure fixed to the outer side of the end of the first pipe 100, and the inner side wall is surrounded by a sealing installation groove 102. The second pipe end boss 201 is an annular structure fixed to the outside of the end of the second pipe 200 and opposite to the first pipe end boss 101. Its end face is fixed with an annular guide connection structure, and two pressing inclined surfaces 202 are symmetrically provided on the other side. The guide connection structure extends into the first pipe 100. The end-face sealing structure is an annular structure, which is located between the mating surfaces of the first pipe end boss 101 and the second pipe end boss 201. A lateral sealing structure is located in the sealing mounting groove 102 and contacts the sidewall of the guide connection structure; The quick-release connection assembly includes a pipe end connecting frame 300 located on the first pipe end boss 101 and the second pipe end boss 201, and an adjustable clamping structure located in the pipe end connecting frame 300. The adjustable clamping structure is in corresponding contact with the pressing inclined surface 202 of the second pipe end boss 201. The intelligent detection module, integrated into the quick-release connection assembly, is used to monitor the connection status parameters of the first pipe 100 and the second pipe 200 in real time and output signals.
[0024] When connecting the first pipe 100 and the second pipe 200, the operator passes the first pipe 100 through the pipe end connector 300 and brings it close to the second pipe 200. The annular guide connection structure on the second pipe end boss 201 will first extend into the inner wall of the first pipe 100, realizing the rapid initial alignment of the pipe and providing a support base for subsequent sealing. Due to the guide connection structure, the pipe is automatically aligned during installation, avoiding the twisting of the sealing ring or pipe stress caused by forced installation, thus extending the service life of the pipeline system.
[0025] Then, operate the movable adjusting clamping structure so that it simultaneously contacts the two pressing inclined surfaces 202 of the second pipe end boss 201, and through the axial locking force generated by the pressing inclined surfaces 202, tightly pull the two pipe end bosses together, thereby achieving rapid locking. When disassembling, simply reverse the operation of the adjusting clamping structure to complete the disassembly.
[0026] Compared to traditional multi-bolt connection disassembly and assembly structures, this invention utilizes quick-release connection components and inclined clamping structures, requiring only one adjustment of the clamping structure to complete locking or releasing, reducing disassembly and assembly time from minutes to seconds, and greatly improving the efficiency of equipment maintenance and cleaning.
[0027] After the first pipe 100 and the second pipe 200 are connected, the intelligent detection module collects the connection status parameters of the pipes in real time. The parameters include temperature, medium leakage, and changes in locking force. When the parameters exceed the set threshold, such as when a slight leak or loosening trend occurs, the module will output a signal to remind maintenance personnel to deal with it in time, thereby avoiding major safety accidents.
[0028] The pipe joint of the present invention adopts a double sealing mechanism: 1. Static end face seal: When the two pipe end bosses come into contact with each other under the action of the quick-release connection assembly, the end face seal structure between the mating surfaces of the two is compressed, forming the first line of defense to prevent the medium from leaking from the gap at the pipe end connection.
[0029] 2. Dynamic radial sealing: As the pipeline is fully connected, the lateral sealing structure in the first pipe end boss 101 is pressed tightly against the outer wall of the guide connection structure, forming a second seal to prevent the medium from leaking through the gap between the inner wall of the pipeline and the guide structure.
[0030] This combination of "end face + radial" has a higher fault tolerance and better sealing effect compared to a single sealing method.
[0031] Therefore, the device of the present invention achieves extremely simplified operation through mechanical structure, ensures reliable connection through double sealing, and endows the device with sensing capabilities through intelligent detection module, which is a significant improvement over traditional chemical pipeline connection methods.
[0032] Example 2 The structure of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 5 As shown, the lateral sealing structure is a lateral sealing ring 500 located in the sealing mounting groove 102, such as... Figure 7As shown, the lateral sealing ring 500 includes a C-shaped sealing ring 501 and a spring ring 502 located on the C-shaped sealing ring 501. The annular opening of the C-shaped sealing ring 501 faces the direction of the second pipe 200, and the inner ring sidewall is in contact with the sidewall of the guide connection structure.
[0033] When the guide connection structure is inserted, it will compress the lateral sealing ring 500. Since there is a spring ring 502 inside the C-type sealing ring 501, the spring ring 502 is compressed and generates a continuous radial rebound force, which pushes the lip of the C-type sealing ring 501 to fit tightly against the side wall of the guide connection structure. During this stage, even if there is no medium pressure in the pipeline, the spring can ensure that the sealing ring is in close contact with the metal wall, forming an initial seal.
[0034] When the pressure of the medium inside the pipeline is high, the medium compresses the C-type sealing ring 501. When the compressive force is low, the C-type sealing ring 501 undergoes a certain deformation and still maintains a seal. When the compressive force is too high, a gap appears between the C-type sealing ring 501 and the guide connection structure, and the medium pressure enters the opening of the C-type sealing ring 501. The pressure of the entering medium acts on the inner wall of the C-type sealing ring 501 and the spring ring 502, further pushing the lip of the C-type sealing ring 501 outward and pressing it against the guide connection structure. The higher the pressure, the greater the contact force between the lip and the metal wall, and the better the sealing effect, thus improving the sealing stability.
[0035] Among them, such as Figure 2 , Figure 6 As shown, the guide connection structure includes a conical ring platform 203 fixed to the second pipe end boss 201. The inner wall radius of the conical ring platform 203 is equal to the inner wall radius of the second pipe 200, and the outer wall end is set as a conical surface. The conical ring platform 203 contacts the inner ring side wall of the C-type sealing ring 501 through its conical surface. The inner side wall end of the first pipe 100 is provided with a limiting conical surface 103 at the corresponding position, and contacts the conical surface of the conical ring platform 203.
[0036] As the second pipe 200 moves toward the first pipe 100, the conical surface of the conical ring platform 203 contacts the limiting conical surface 103 at the end of the first pipe 100, forming a set of conical positioning pairs. As the compression continues, they will wedge each other tightly, forcing the axes of the two pipes to completely coincide, achieving precise alignment and automatic centering, ensuring the concentricity of the pipe connection, avoiding local stress concentration or uneven compression of the sealing ring caused by eccentricity, and forming a support structure through the conical ring platform 203 and the limiting conical surface 103, eliminating the support pressure of the lateral sealing ring 500, so that it only needs to provide a sealing function.
[0037] During the movement of the conical ring platform 203, the conical surface will gradually press against the C-type sealing ring 501 installed in the first pipe end boss 101. Due to the conical surface contact, the axial clamping force will be converted into radial compression force on the C-type sealing ring 501 through the conical surface slope, so that the lip of the C-type sealing ring 501 is tightly attached to the surface of the conical ring platform 203, thereby achieving lateral sealing during pipe connection.
[0038] Example 3 The structure of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 3 As shown, the adjusting clamping structure includes an upper clamping seat 301 and a lower clamping seat 400 located on the upper and lower sides of the inner side of the pipe end connecting frame 300, respectively. The upper clamping seat 301 is fixed to the pipe end connecting frame 300, and the lower clamping seat 400 is slidably connected to the pipe end connecting frame 300 in the vertical direction. The upper clamping seat 301 and the lower clamping seat 400 are respectively provided with an upper clamping groove 302 and a lower clamping groove 401 on their opposite surfaces. One side wall of the upper clamping groove 302 and the lower clamping groove 401 is set vertically, and the other side wall is set inclined. The upper clamping seat 301 and the lower clamping seat 400 contact the outer surface of the first pipe end boss 101 through the vertical side wall, and contact the pressing inclined surface 202 on the second pipe end boss 201 through the inclined side wall. A connecting ring platform 405 is fixed at the center of the bottom of the lower bracket 400, and an adjusting shaft 403 is rotatably connected to the connecting ring platform 405. The adjusting shaft 403 is threadedly connected to the bottom of the pipe end connecting bracket 300. The bottom sides of the lower bracket 400 are connected to the bottom of the pipe end connecting bracket 300 by springs, and two vertical guide shafts 402 are symmetrically fixed thereon. The bottom ends of the guide shafts 402 extend out of the pipe end connecting bracket 300 and are slidably connected to it.
[0039] When the first pipe end boss 101 and the second pipe end boss 201 contact and are located inside the pipe end connecting frame 300, the pipe end connecting frame 300 moves downward, so that the tops of the first pipe end boss 101 and the second pipe end boss 201 are located in the upper slot 302. Then the operator rotates the adjusting shaft 403. Since the adjusting shaft 403 is threadedly connected to the pipe end connecting frame 300 and is limited and guided by the guide shaft 402, the rotational motion is converted into the up and down linear motion of the adjusting shaft 403. Then, the lower slot 400 is pushed upward by the adjusting shaft 403, and the bottoms of the first pipe end boss 101 and the second pipe end boss 201 enter the lower slot 401. When the lower card holder 400 moves upward, the vertical sidewalls of the upper and lower card slots 401 contact the outer side of the first pipe end boss 101, and the inclined sidewalls simultaneously contact the pressing inclined surface 202 of the second pipe end boss 201. As the lower card holder 400 continues to move, the inclined sidewalls slide along the inclined surface of the second pipe end boss 201 and generate a horizontal axial thrust on the second pipe end boss 201, thereby tightly pulling the two pipe end bosses together and completing the connection operation of the two pipes.
[0040] During disassembly, simply rotate the adjusting shaft 403 in the opposite direction. The adjusting shaft 403 will cause the lower clamping seat 400 to move downward, and the inclined side wall will disengage from the pressing inclined surface 202. The vertical side wall will also disengage from the first pipe end boss 101. The entire clamping structure will be released, and the pipe can be quickly separated.
[0041] The vertical sidewalls of the upper and lower slots 401 in this structure serve as positioning references, while the inclined sidewalls are specifically responsible for applying thrust, making the locking process more stable and preventing the already aligned pipe from being disturbed by the applied force. Furthermore, the simultaneous locking of the upper and lower sides of the pipe by the inclined sidewalls of the upper and lower slots 400 ensures that the force and position of the pipe remain stable during locking.
[0042] Among them, such as Figure 4 As shown, a vertical liquid collection hole 406 is provided at the bottom center of the lower slot 401. The liquid collection hole 406 passes through the connecting ring platform 405, and a vertical liquid collection tube 404 is threadedly connected to the inner side of the connecting ring platform 405. A vertical through hole is provided at the center of the adjusting shaft 403. The liquid collection tube 404 is located at the center of the adjusting shaft 403, and its bottom end extends out of the adjusting shaft 403 and is set as a closed end.
[0043] When a pipeline connection seal fails and a leak occurs, the leaked chemical medium will flow downwards under gravity, collect in the collection hole 406 of the lower slot 401, and enter the connected collection capillary 404. It will flow vertically downwards along the capillary, and the leaked liquid will be temporarily collected and stored in the capillary, preventing it from dripping directly onto the external environment or equipment. A liquid level sensor, pH electrode, or specific gas sensor can be installed near the closed end. Once the presence of liquid is detected, an alarm can be triggered. Combined with an intelligent detection module, real-time monitoring of early micro-leakage can be achieved, issuing an alarm before the leak expands.
[0044] Among them, such as Figure 3 As shown, the adjusting shaft 403 includes a smooth shaft section 403a rotatably connected to the connecting ring platform 405, a threaded shaft section 403b coaxially fixed to the bottom end of the smooth shaft section 403a, and a screwing boss 403c fixed to the outer side of the bottom end of the threaded shaft section 403b. The bottom center of the pipe end connecting bracket 300 is provided with a threaded ring platform 303. The center of the threaded ring platform 303 is provided with a threaded hole and is threadedly connected to the threaded shaft section 403b. The outer side wall of the screwing boss 403c is provided with anti-slip texture, realizing the rotational connection, threaded adjustment and screwing functions of the adjusting shaft 403 and the lower bracket 400.
[0045] When transporting colorless media in chemical pipelines, the collecting capillary 404 is filled with a color-developing liquid or reagent. This reagent reacts with the colorless media entering the collecting capillary 404 when a leak occurs at the pipeline connection, producing a color that is easy to monitor.
[0046] Example 4 The structure of this embodiment is basically the same as that of embodiment one, except that the intelligent detection module includes a sensor unit for monitoring pipeline connection status parameters, a signal processing unit electrically connected to the sensor unit, and an output unit electrically connected to the signal processing unit. The signal processing unit has a preset threshold and uses a microcontroller with a built-in threshold comparison program. When the parameter detected by the sensor unit exceeds the threshold, it generates a trigger signal and controls the output unit to output an alarm signal.
[0047] The output unit includes a local alarm and a remote communication module. The local alarm uses LED indicator lights or a buzzer to emit an audible and visual alarm locally on the device. The remote communication module sends the alarm signal to the central control room or a mobile terminal to achieve remote early warning.
[0048] The sensor unit includes a leakage sensor, a force sensor, and a temperature sensor. The leakage sensor can be a liquid level sensor at the bottom of the pipe end connector 300 or a gas sensor at the top of the pipe end connector 300, used to monitor medium leakage. The force sensor uses a strain gauge attached to the adjusting clamping structure or the pipe end connector 300, used to monitor changes in the locking force, i.e., the loosening trend. The temperature sensor uses a thermocouple or a resistance temperature detector (RTD), used to monitor temperature anomalies at the pipe connection.
[0049] Example 5 The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the end face sealing structure is an annular end face sealing ring 600, which provides a stable static sealing base. Its material is polytetrafluoroethylene or metal, which has excellent chemical corrosion resistance and high temperature resistance. The polytetrafluoroethylene sealing ring is suitable for sealing requirements of high temperature, high pressure and strong corrosive media, and has good high pressure resistance, high temperature resistance and corrosion resistance. The metal sealing ring can be a flexible graphite composite metal gasket, metal O-ring or metal flat gasket, etc., which is suitable for sealing requirements of high pressure, high temperature and strong corrosive media.
