Description

Technical Field

[0001] The invention relates to the technical field of fluid pipeline processing, in particular to a fluid pipeline vulcanization device. Background Art

[0002] Fluid conveying pipelines are widely used in the field of media transportation. Rubber hoses are a major type of fluid pipeline. Vulcanization is a key step in the manufacture of rubber fluid pipelines. It is usually achieved by heating to form a cross-linked structure between rubber molecular chains, which can significantly improve the physical properties of the rubber.

[0003] At present, the commonly used vulcanization method in the field of rubber fluid pipeline processing is steam vulcanization, such as the vulcanization method for rubber hoses described in the Chinese patent publication number CN111594667A, which is to pass high-temperature and high-pressure steam into the pipeline to be vulcanized, and seal the two ends of the pipeline with plug-type sealing parts, and maintain it for a period of time until the vulcanization is completed.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the current steam vulcanization method for rubber fluid pipelines has high steam production costs, and the release of high-temperature waste steam after vulcanization is harmful to the work site environment, equipment and personnel. Therefore, it is of great significance to the art to design a vulcanization product that can effectively vulcanize rubber fluid pipelines and is safer and has lower long-term use costs. Summary of the invention

[0005] In order to improve the current problems of high cost of steam vulcanization and damage to the work site environment, equipment and personnel caused by the release of waste steam after vulcanization, the purpose of the present invention is to provide a new fluid pipeline vulcanization equipment, which mainly uses hot water as the vulcanization medium and can achieve fully automatic vulcanization, which is safer for the work site environment, equipment and personnel, and has lower long-term use costs than steam vulcanization.

[0006] In order to achieve the purpose of the present invention, the present invention provides a fluid pipeline vulcanization equipment, which adopts the following technical solution:

[0007] A vulcanization device for a fluid pipeline, comprising:

[0008] A vulcanizing roller, the interior of which is a hollow cavity, the two axial ends of the vulcanizing roller are closed, and at least one end of the vulcanizing roller is provided with a water injection port;

[0009] A heating assembly is arranged in the vulcanizing roller;

[0010] The clamping mechanism is arranged at both ends of the axial direction of the vulcanizing roller.

[0011] In the above technical solution, the interior of the vulcanization roller is used for water injection and heating to form a high-temperature vulcanization roller. The pipe to be vulcanized is sleeved outside the vulcanization roller along the axial direction of the vulcanization roller. The pipes are fixed by clamping mechanisms at both ends of the pipes, so that the pipes to be vulcanized absorb the heat of the vulcanization roller to achieve vulcanization. After the vulcanization is completed, the waste water in the vulcanization roller can be discharged. Through the above technical solution, the pipe to be vulcanized is fully unfolded and sleeved outside the vulcanization roller, and fully exchanges heat with the vulcanization roller, with a vulcanization efficiency equivalent to that of steam vulcanization. The hot water vulcanization method adopted by the present invention avoids a large amount of waste gas pollution and high-temperature steam damage caused by the discharge of high-temperature waste steam, and is safer to use. At the same time, the cost of hot water vulcanization is lower than that of steam vulcanization.

[0012] Implementations may include any or all of the following features.

[0013] In one embodiment, a flange is installed on the end face of one axial end of the vulcanization roller, a water injection pipe is installed on the flange, the water injection pipe is connected to the cavity inside the vulcanization roller, and the water injection port is arranged on the water injection pipe.

[0014] Through the above technical solution, one axial end of the vulcanization roller is closed by a flange, and the water injection port is opened when water is injected, and the water injection port is closed after the water injection is completed. In some embodiments of the above technical solution, after the vulcanization is completed, the water in the vulcanization roller can be discharged through the water injection port. In some other embodiments of the above technical solution, the water in the vulcanization roller does not need to be discharged every time the vulcanization is completed, and the water injected into the vulcanization roller can be reused.

[0015] In one embodiment, the heating assembly includes a heating tube and a joint, the heating tube and the joint are connected, the heating tube is passed through and fixed on a side of the flange facing the inside of the vulcanizing roller, and the joint passes through the flange and is located outside the vulcanizing roller.

[0016] Through the above technical solution, the effect of installing the heating tube inside the vulcanizing roller can be achieved while ensuring that the flange can seal one end of the heating roller. In some embodiments of the above technical solution, the heating tube and the joint are connected as one piece, and a nut is screwed to the connection part of the joint with the flange when the joint passes through the flange, and the axial end face of the nut is tightly pressed against the end face of the flange to reduce the possibility of water leakage at the connection part between the heating tube and the flange. In other embodiments, a water stop washer can be placed between the nut and the flange, and the water stop washer can be sleeved on the heating tube or the joint.

[0017] In one embodiment, the vulcanization roller is provided with a hole, and the hole penetrates the wall of the vulcanization roller along the thickness direction of the wall of the vulcanization roller.

[0018] Through the above technical scheme, the hot water in the vulcanization roller can enter between the vulcanization roller and the pipe to be vulcanized through the hole, and the hot water directly exchanges heat with the pipe to be vulcanized, which is more efficient than heat transfer through the wall of the vulcanization roller, and helps to improve the vulcanization efficiency. When the above technical scheme is implemented, the pipe openings at both ends of the pipe to be vulcanized must be compressed and sealed by a clamping mechanism to avoid water leakage. When the above technical scheme is implemented, when the fluid pipeline is removed from the surface of the vulcanization roller after vulcanization is completed, the hole leaks out, and the water in the vulcanization roller flows out from the hole, achieving the effect of removing the pipe while draining water. At this time, the water discharged from the hole can lubricate the pipe and accelerate the removal of the pipe. When the above technical scheme is implemented, each time vulcanization is completed, the water in the vulcanization roller is almost drained, and the vulcanization roller needs to be refilled with water before each round of vulcanization.

[0019] In one embodiment, an air inlet pipe is further provided on the flange, the air inlet pipe is communicated with the cavity inside the vulcanizing roller, and an air inlet port is provided on the air inlet pipe, and the air inlet port is located outside the vulcanizing roller.

[0020] In the above technical solution, the holes on the vulcanization roller can be used as water holes and air holes at the same time. When the pipe to be vulcanized is sleeved on the vulcanization roller, air is ventilated into the vulcanization roller through the air inlet, and the pipe to be vulcanized is expanded during the process of air blowing out from the hole, so that the pipe does not generate sliding friction with the outer wall of the vulcanization roller when it is sleeved on the vulcanization roller, so that the pipe is easy to sleeve on the vulcanization roller. After the pipe is sleeved, the air inlet is closed, and the water injection port is opened to inject water into the vulcanization roller. At this time, the hole can be used as a water hole.

[0021] In one embodiment, the clamping mechanism includes at least two clamping cylinders, which are located at both ends of the axial direction of the vulcanization roller. The clamping cylinder includes a push rod portion and a clamping portion. The clamping portion is installed at one end of the push rod portion facing the vulcanization roller. In the clamping state, the clamping portion is sleeved and clamped outside the vulcanization roller.

[0022] Through the above technical solution, the pressing cylinders at both ends of the vulcanizing roller press on the pipe arranged outside the vulcanizing roller, clamp the pipe and the vulcanizing roller, and prevent water from leaking from between the pipe and the vulcanizing roller.

[0023] In one embodiment, the clamping mechanism includes at least two clamping cylinders, which are located at both ends of the axial direction of the vulcanization roller, and the clamping cylinder includes a push rod portion and a clamping portion, and the clamping portion is installed at one end of the push rod portion facing the vulcanization roller; when the clamping cylinder located at the end of the vulcanization roller where the flange is installed is in a clamping state, the clamping portion is sleeved and clamped outside the vulcanization roller; the clamping cylinder located at the end of the vulcanization roller away from the flange is spaced apart from the end of the vulcanization roller.

[0024] In the above technical solution, the end of the vulcanizing roller away from the flange can be integrally sealed, and after the pipe is sleeved on the vulcanizing roller, a plug-type seal can be inserted into the pipe away from the end of the flange to seal the pipe mouth of the pipe, and then the plug-type seal serves as the inner core of the pipe to provide a force point for the clamping cylinder away from the end of the flange, and the clamping cylinder is pressed on the pipe outside the plug-type seal to prevent water from leaking out. In this embodiment, the heat of the end of the vulcanizing roller away from the flange and its end face can be fully used for vulcanization, and holes can also be opened on the roller wall of the end of the vulcanizing roller, so as to fully utilize the heat energy and improve the vulcanization efficiency.

[0025] In one embodiment, it also includes a clamping and fixing block, which is used in conjunction with the clamping cylinder located at the end of the vulcanizing roller away from the flange plate; in a working state, the clamping and fixing block is inserted into the pipe mouth of the pipe to be vulcanized, and the clamping part of the clamping cylinder located at the end of the vulcanizing roller away from the flange plate is sleeved and clamped outside the clamping and fixing block.

[0026] Through the above technical solution, a clamping and fixing block is provided as a sealing member to seal the pipe opening of the pipeline, and is also used as a fulcrum for clamping the cylinder.

[0027] In one embodiment, a belt threading mechanism is provided below the vulcanization roller, and the belt threading mechanism includes a belt threading track, and the belt threading track is extended along the axial direction of the vulcanization roller. A belt threading trolley is slidably connected to the belt threading track, and a belt threading member is installed at one end of the belt threading trolley away from the belt threading track, and the central axis of the belt threading member is colinear with the central axis of the vulcanization roller.

[0028] Through the above technical solution, one end of the pipe to be vulcanized is fixed on the threading piece, and the threading piece makes the pipe opening fully open and circular. During the movement of the threading trolley, the pipe is threaded on the vulcanizing roller and removed from the vulcanizing roller after vulcanization is completed.

[0029] In one embodiment, a detection mechanism is disposed above the vulcanization roller, and the detection mechanism includes a detection track, the detection track is extended along the axial direction of the vulcanization roller, and a thermal imager is slidably connected to the detection track.

[0030] Through the above technical solution, after the vulcanization time is completed, the thermal imager moves on the detection track to detect the temperature of the pipe surface after vulcanization. When a section of the pipe is unevenly vulcanized or damaged, its surface temperature will be different from the surrounding temperature, thereby detecting whether the vulcanization of the pipe is qualified, achieving the effect of automatic detection, saving manpower, and avoiding burns from manual inspection.

[0031] In summary, the present invention provides a vulcanization device for a fluid pipeline, which has the following beneficial effects:

[0032] First, the present invention designs a set of vulcanization equipment specifically for fluid pipelines for hydrothermal vulcanization, which replaces the traditional steam vulcanization method, reduces the vulcanization cost, and at the same time improves the safety of the work site environment, equipment and personnel.

[0033] Secondly, the equipment of the present invention realizes the integrated and automated operation of loading, vulcanization, quality inspection and unloading, which increases the production efficiency as well as the safety and accuracy in the quality inspection process and has a higher level of intelligence.

[0034] Third, the present invention improves the design of the vulcanizing roller so that the vulcanizing roller integrates the effects of ventilation and water flow, greatly reducing the difficulty of loading and unloading the fluid pipeline to the vulcanizing roller, and also effectively improves the heat transfer efficiency between the hot water and the pipeline to be vulcanized, thereby promoting vulcanization.

[0046] In order to make the purpose and technical solution of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The directional terms mentioned in the following implementation methods, such as: up, down, left, right, front, back, bottom, top, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are for illustration, not for limitation of the present invention.

[0047] The embodiment of the present invention discloses a fluid pipeline vulcanization device, wherein the fluid pipeline mainly refers to a rubber hose used to transport fluid medium, and the rubber hose is usually a product after vulcanization and cross-linking. The fluid pipeline is referred to as a pipeline hereinafter, and the outer diameter of the pipeline is usually φ200mm~φ300mm. The vulcanization device of the present invention is mainly used to completely replace the traditional steam vulcanization method, and provides a more automated and safe hydrothermal vulcanization method, and this safety includes safety for the environment and safety for construction personnel.

[0048] Reference Figure 1 A vulcanization device for a fluid pipeline disclosed in an embodiment of the present invention includes a vulcanization roller 1, and the vulcanization roller 1 is fixed to the ground or other equipment plane by connecting a fixing structure at its end. A clamping mechanism 3 is arranged on both sides of the vulcanization roller 1, which is used to press the pipeline against the surface of the vulcanization roller 1. A belt threading mechanism 4 is arranged below the vulcanization roller 1, which is used to carry the pipeline to be vulcanized and put the pipeline to be vulcanized on the vulcanization roller 1, and carry the pipeline to be removed from the vulcanization roller 1 after vulcanization is completed. A detection mechanism 5 is arranged above the vulcanization roller 1, which is used to detect the vulcanization quality of the pipeline after vulcanization is completed.

[0049] Specifically, refer to Figure 1The vulcanization roller 1 has a hollow cavity 11 inside, and one end of the vulcanization roller 1 is integrally formed to form a closure. This integrally formed closure can make the end face of the vulcanization roller 1 spherical or arc-shaped, so that the end face and the side wall of the vulcanization roller 1 form a rounded transition connection. It will be easier to pass or remove the pipeline from this end to the vulcanization roller 1, and it will also greatly reduce the risk of the vulcanization roller 1 causing scratches on the pipeline. The end of the vulcanization roller 1 axially away from the integral closure is equipped with a flange 12 to form a closure, and the end of the vulcanization roller 1 equipped with the flange 12 is equipped with a mounting block 2. The upper end of the mounting block 2 is sleeved and fixed on the outer peripheral surface of the vulcanization roller 1. The mounting block 2 has a certain height, and the lower end of the mounting block 2 is fixed on the ground or the surface of other equipment. The mounting block 2 supports, fixes and elevates the vulcanization roller 1, so as to facilitate the installation and removal of the pipeline from one end of the vulcanization roller 1 to the vulcanization roller 1.

[0050] Reference Figure 2 A water injection pipe 13 is installed on the flange 12. One end of the water injection pipe 13 penetrates into the vulcanization roller 1 and communicates with the cavity 11 of the vulcanization roller 1. One end of the water injection pipe 13 located outside the vulcanization roller 1 forms a water injection port 131. The water injection pipe 13 is installed with an electronic pressure relief valve 133 and a one-way solenoid valve 132. The electronic pressure relief valve 133 is installed between the outer end surface of the flange 12 and the one-way solenoid valve 132. The one-way solenoid valve 132 opens in the direction of the arrow A shown in the figure, so that the water in the vulcanization roller 1 cannot flow out from the water injection port 131.

[0051] Reference Figure 2 The vulcanization equipment further includes a heating assembly 14, which is installed in the vulcanization roller 1 through a flange 12. The heating assembly 14 includes a heating tube 141 and a joint 142, which are connected in an integral manner. The heating tube 141 is located on the side of the flange 12 facing the inside of the vulcanization roller 1, and the end of the heating tube 141 passes through the flange 12 to form a joint 142 outside the vulcanization roller 1 for connecting electricity. The heating tube 141 is arranged in the vulcanization roller 1 along the axial direction of the vulcanization roller 1, and the end of the heating tube 141 close to the flange 12 is defined as the front end, and the end away from the flange 12 is defined as the end. In a specific embodiment, the end of the heating tube 141 is close to the end face of the vulcanization roller 1. The heating tube 141 can be linear or spiral, and the heating tube 141 can be plural. In a specific embodiment, the heating assembly 14 can be an electric heating tube 141.

[0052] Reference Figure 2 An air inlet pipe 15 is also installed on the flange 12. The air inlet pipe 15 passes through the flange 12 and is connected to the cavity 11 of the vulcanizing roller 1. The end of the air inlet pipe 15 located outside the vulcanizing roller 1 has an air inlet 151. The air inlet 151 is installed with a solenoid valve 152. An electronic pressure gauge 153 is installed between the outer end surface of the flange 12 and the solenoid valve 152.

[0053] Reference Figure 1 The wall of the vulcanization roller 1 is provided with a hole 16, which penetrates the wall of the vulcanization roller 1 along the wall thickness direction of the vulcanization roller 1 and is connected with the cavity 11 of the vulcanization roller 1. A plurality of holes 16 are evenly arranged along the axial direction and the circumferential direction of the vulcanization roller 1. The holes 16 are used as air outlet holes 16 when the pipeline is passed through the vulcanization roller 1, and are used as water outlet holes 16 when the pipeline is removed from the vulcanization roller 1 after vulcanization. In some embodiments, the end of the vulcanization roller 1 away from the flange 12 may also have a hole 16.

[0054] Reference Figure 1 The clamping mechanism 3 includes at least two clamping cylinders 31, and at least one clamping cylinder 31 is provided at each end of the axial ends of the vulcanization roller 1. The clamping cylinder 31 includes a push rod portion 311 and a clamping portion 312. The push rod portion 311 is fixed above the vulcanization roller 1 along the radial direction of the vulcanization roller 1, and the clamping portion 312 is connected to one end of the push rod portion 311 facing the vulcanization roller 1. The clamping portion 312 can be a pneumatic clamp with a clamping hoop, and the clamping hoop is composed of two semicircular rings clasped into a circular ring for clamping outside the pipeline. In the clamped state, the axial central axis of the clamping portion 312 is colinear with the axis of the vulcanization roller 1. In a specific embodiment, at one end of the vulcanization roller 1 where the flange 12 is provided, the clamping cylinder 31 is located on the left side of the mounting block 2, and the clamping cylinder 31 at this end is provided close to the mounting block 2, and the mounting block 2 is installed at the rightmost end of the vulcanization roller 1, so as to expose more of the roller body of the vulcanization roller 1, so that the length of the vulcanization roller 1 sleeved with the pipeline is extended as much as possible. The extension lines of the push rod parts 311 of the clamping cylinder 31 at both ends of the axial direction of the vulcanization roller 1 are intersected with the roller body of the vulcanization roller 1. When clamping, the clamping part 312 is clamped on the pipeline outside the vulcanization roller 1, and the roller body of the vulcanization roller 1 is used as the supporting point to form a seal on both ends of the pipeline. In this embodiment, the end of the vulcanization roller 1 away from the flange 12 does not have a hole 16.

[0055] Regarding the installation position of the clamping mechanism 3, refer to Figure 1In a preferred embodiment, the extension line of the push rod part 311 of the clamping cylinder 31 at one end of the flange 12 intersects with the roller body of the vulcanizing roller 1. There is a distance M between the clamping cylinder 31 at one end away from the flange 12 and the end of the vulcanizing roller 1, that is, the extension line of the push rod part 311 of the clamping cylinder 31 at one end away from the flange 12 does not intersect with the roller body of the vulcanizing roller 1, so that the heat of the end of the upper vulcanizing roller 1 away from the flange 12 can be effectively utilized to improve the vulcanization efficiency. In this embodiment, the end of the vulcanizing roller 1 away from the flange 12 can also have a hole 16, for example, the hole 16 is opened at the bottom of the spherical surface or arc surface of the end of the vulcanizing roller 1. In this embodiment, after the pipeline is sleeved on the vulcanizing roller 1, the clamping cylinder 31 at one end of the flange 12 uses the roller body of the vulcanizing roller 1 as a support point, clamps on the pipeline outside the vulcanizing roller 1, and seals the pipeline opening at one end of the flange 12. The pipe port plug at one end away from the flange 12 is provided with a clamping and fixing block 6 to block the pipe port at that end. When clamping, the clamping cylinder 31 uses the clamping and fixing block 6 as a supporting point, clamps on the pipe outside the clamping and fixing block 6, and seals the pipe port at the other end. A matching structure 7 can be provided between the clamping and fixing block 6 and the vulcanizing roller 1, and the clamping and fixing block 6 and the vulcanizing roller 1 are detachably connected through the matching structure 7, so that the clamping and fixing block 6 is coaxial with the vulcanizing roller 1 in the installed state, reducing the possibility of the pipe twisting and wrinkling caused by the clamping and fixing block 6 when in use, and at the same time improving the installation stability of the clamping and fixing block 6.

[0056] Reference Figure 3 The matching structure 7 can be a connection piece (71, 72) that can be hooked together and respectively arranged on the two opposite surfaces of the clamping and fixing block 6 and the vulcanizing roller 1. After the clamping and fixing block 6 is inserted into the pipe opening, the first connection piece 71 of the clamping and fixing block 6 facing the vulcanizing roller 1 and the second connection piece 72 at the top end of the end surface of the vulcanizing roller 1 are hooked together.

[0057] Reference Figure 1The belt threading mechanism 4 includes a belt threading track 41, a belt threading trolley 42 and a belt threading member (not shown in the figure). The belt threading track 41 is laid along the axial direction of the vulcanizing roller 1. The belt threading track 41 can be installed on the ground or on other equipment planes. The belt threading trolley 42 is slidably connected to the belt threading track 41, and the belt threading member is fixed to one end of the belt threading trolley 42 facing the vulcanizing roller 1. The central axis of the belt threading member is colinear with the central axis of the vulcanizing roller 1. When in use, the pipe port is fixed to the belt threading member in a fully opened state, and the belt threading member is driven by the belt threading trolley 42 to be installed outside the vulcanizing roller 1 and move along the axial direction of the vulcanizing roller 1 to complete the installation and removal of the pipe on the vulcanizing roller 1. In some embodiments, the tape-threading trolley 42 may be located directly below the vulcanizing roller 1, and the top of the tape-threading trolley 42 is at a certain distance from the vulcanizing roller 1, and the tape-threading piece is in a Y-shape or annular shape or two symmetrical semicircular shapes fixed to the top of the tape-threading trolley 42, and the tape-threading piece is arranged around the outer circumference of the vulcanizing roller 1 when in use. There is no particular limitation on the fixing method of the pipeline and the tape-threading piece, and a common fixing method may be used, such as clamping the edge of the pipeline on the tape-threading piece with a clip, a buckle, etc., or clamping the pipeline on the tape-threading piece with a clamp outside the pipeline.

[0058] Reference Figure 1 The detection mechanism 5 includes a detection track 51 and a thermal imager 52. The detection track 51 is fixed above the vulcanization roller 1 along the axial direction of the vulcanization roller 1, and the thermal imager 52 is slidably connected to the detection track 51. After the vulcanization is completed, the thermal imager 52 moves linearly along the detection track 51 at least once to scan the temperature of the pipeline surface after the vulcanization is completed. If there is a temperature difference between the surface temperature of a certain part of the pipeline and the temperature of the nearby area that exceeds the error range, it is indicated that the vulcanization of this part is unqualified and needs to be re-vulcanized.

[0059] In some embodiments, the tape-threading trolley 42, the clamping cylinder 31, the solenoid valve 152 of the air inlet 151, the electronic pressure gauge 153, the one-way solenoid valve 132 of the water injection port 131, the heating tube 141, and the thermal imager 52 are all electrically connected to the console. The tape-threading action of the tape-threading trolley 42 is set to be synchronized with the opening action of the solenoid valve 152 of the air inlet 151. A position sensor can be installed on the inner side of the mounting block 2, and the position sensor is electrically connected to the console. After the position sensor is set to transmit a correct position signal to the console, the console can automatically control the closing action of the solenoid valve 152 of the air inlet 151.

[0060] The use process of a fluid pipeline vulcanization device according to an embodiment of the present invention is as follows: the threading trolley 42 is moved to the end of the vulcanization roller 1 away from the end of the flange 12, one end of the pipeline to be vulcanized is fixed on the threading piece, the threading trolley 42 is moved, and the pipeline to be vulcanized is put on the vulcanization roller 1 as a whole. In this process, in order to ensure smooth threading, the threading trolley 42 triggers the solenoid valve 152 of the air inlet 151 to act synchronously when the threading action is performed, so that compressed air enters the vulcanization roller 1, and continuously discharges gas through the hole 16 on the vulcanization roller 1 and blows into the inside of the pipeline at the same time, so that the pipeline expands during the threading process. When the end of the pipeline to be threaded reaches the end of the vulcanization roller 1, that is, the end of the flange 12, the position sensor is triggered to act, the solenoid valve 152 of the air inlet 151 is controlled to be closed, and the clamping cylinder 31 is operated. First, start the clamping cylinder 31 at one end of the flange 12 of the vulcanizing roller 1, the push rod part 311 extends, and the clamping part 312 presses the pipeline against the surface of the vulcanizing roller 1 along the circumference of the pipeline, and seals the pipeline opening at this end. Then put the clamping block 6 into the pipeline away from the end of the flange 12, and connect the clamping block 6 with the vulcanizing roller 1 through the matching structure 7, and start the clamping cylinder 31 away from the end of the flange 12, so that the push rod part 311 extends, and the clamping part 312 presses the pipeline against the surface of the clamping block 6 along the circumference of the pipeline, and seals the pipeline opening at this end. At this time, both ends of the pipeline are in a sealed state, triggering the one-way solenoid valve 132 at the water injection port 131 to operate, so that water is injected into the vulcanizing roller 1 according to the amount set by the general process parameters. At this time, the vulcanizing roller 1 is in a mixed state of gas and water, with the proportion of water being higher than the proportion of gas, and the vulcanizing roller 1 has a certain pressure. After the water injection is completed, the water injection port 131 is closed, and the heating pipe 141 in the vulcanizing roller 1 is operated to start working, and the water in the vulcanizing roller 1 is heated. According to the general process flow, the heating and pressure maintenance are carried out according to the pre-set heating time and pressure. When the electronic pressure gauge 153 detects that the pressure is too high, the pressure can be released through the electronic pressure relief valve 133. When the vulcanization time is up, the thermal imager 52 above the vulcanizing roller 1 is activated, and two imaging scans are performed from front to back. After the test is qualified, the vulcanization of the fluid pipeline is completed. After that, the clamping part 312 of the clamping cylinder 31 at both ends of the pipeline is released, the push rod part 311 rises, and the belt threading trolley 42 moves in the reverse direction to remove the pipeline from the vulcanizing roller 1. As the pipeline is removed, the water in the vulcanizing roller 1 continuously flows out from the hole 16, which plays a lubricating role in the removal of the pipeline while draining water.
