Description

Technical Field

[0001] This utility model belongs to the field of fluoropolymer lining molds, specifically a fluoropolymer lining mold for regulating valves with high uniformity. Background Technology

[0002] Control valves are important equipment in industrial automation process control, used to regulate parameters such as fluid flow, pressure, and temperature. They control fluid flow by changing the cross-sectional area of ​​the fluid channel to meet the requirements of the process. Fluorine lining of control valves is a process of lining the fluid-contacting parts of the control valve with a layer of fluoroplastic to improve the corrosion resistance and sealing performance of the control valve, enabling it to adapt to harsher operating conditions.

[0003] Heating the fluoropolymer-lined mold is crucial for ensuring the quality and performance of the fluoropolymer lining. Typically, electric heating elements such as heating tubes or heating wires are used to convert electrical energy into heat energy, which is then transferred to the mold via heat conduction. However, since the heating tubes and wires are arranged in multiple evenly distributed sections inside the mold, if a heating tube or wire malfunctions, the worker cannot detect the problem visually. This results in uneven temperature distribution between the damaged area and the surrounding environment, ultimately affecting the quality of the final product.

[0004] In summary, this utility model provides a fluoropolymer-lined mold for regulating valves with high uniformity to solve the above-mentioned problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 The image shown is the first embodiment of this utility model. This embodiment provides a fluoropolymer-lined mold for a regulating valve with high uniformity, comprising:

[0024] The mold unit 1 includes a base plate 101, side plates 102 fixedly connected to the top two sides of the base plate 101, a mold body 103 disposed at the front end between the two side plates 102, an infrared thermal imager 104 disposed at the rear end between the two side plates 102, and a clamping assembly 105 disposed on the surface of the mold body 103.

[0025] The mounting unit 2 includes a rotating column 201 movably connected between two side plates 102 via a damping bearing, a mounting bracket 202 fixedly connected to the surface of the rotating column 201, a limiting frame 203 disposed on the top of the mounting bracket 202, and a positioning component 204 disposed between the mounting bracket 202 and the limiting frame 203.

[0026] like Figure 1-4 As shown, the base plate 101 and the side plate 102 form a basic frame, providing a stable support structure. The mold body 103 directly supports the regulating valve and accommodates the fluoroplastic material to form a fluoropolymer lining. The infrared thermal imager 104 is used to monitor the surface temperature distribution of the mold body 103 in real time and detect local overheating areas so as to detect the damage of the heating wire in time and prevent the uneven temperature inside the mold body 103 caused by the failure to detect the damage of the heating wire in time, thereby ensuring uniform fluoropolymer lining. The clamping assembly 105 is used to fix the position of the regulating valve to prevent displacement during processing. The rotating column 201 cooperates with the damping bearing to support the rotation of the mounting frame 202 so as to adjust the angle of the infrared thermal imager 104. The mounting frame 202 and the limiting frame 203 are used to fix the infrared thermal imager 104 and limit its installation position. The positioning assembly 204 is used to realize the quick disassembly and precise positioning of the mounting frame 202 and the limiting frame 203.

[0027] Example 2

[0028] Reference Figure 2 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, the clamping assembly 105 includes clamping plates 1051 disposed on both sides of the mold body 103, a fixing rod 1052 fixedly connected between the left side plate 102 and the clamping plate 1051, a threaded rod 1053 threadedly connected to the inner cavity of the right side plate 102, the left end of the threaded rod 1053 being movably connected to the right side clamping plate 1051 via a bearing, and a limiting rod 1054 fixedly connected to the right side of the right side clamping plate 1051, the right end of the limiting rod 1054 penetrating the right side plate 102 and being slidably connected to its inner cavity.

[0030] The positioning component 204 includes mounting grooves 2041 formed on both sides of the top of the mounting frame 202, and mounting blocks 2042 fixedly connected to both sides of the bottom of the limiting frame 203. The bottom of the mounting blocks 2042 extends into the inner cavity of the mounting grooves 2041 and is detachably connected to the inner cavity of the mounting grooves 2041. The infrared thermal imager 104 is detachably connected to the inner cavities of the mounting frame 202 and the limiting frame 203.

[0031] like Figure 2 and 3 As shown, the left fixing rod 1052 and the right threaded rod 1053 cooperate to fix and adjust the two clamping plates 1051 respectively, realizing bidirectional synchronous clamping. The limiting rod 1054 is used to prevent the clamping plate 1051 from shifting when the threaded rod 1053 rotates. The mounting groove 2041 and the mounting block 2042 adopt a mortise and tenon structure design, which is convenient to install and has strong shear resistance.

[0032] Example 3

[0033] Reference Figure 2 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, the positioning component 204 further includes a push post 2043 slidably connected to the front and back sides of the limiting frame 203, a locking post 2044 slidably connected to the front and back sides of the inner cavity of the mounting block 2042, and a slot 2045 formed on the front and back sides of the mounting bracket 202. One end of the locking post 2044 extends into the inner cavity of the slot 2045 and engages with its inner cavity.

[0035] The positioning assembly 204 also includes a connecting piece 2046 fixedly connected to the back of the push post 2043 and the locking post 2044, a stainless steel compression spring 2047 fixedly connected between the inner wall of the limiting frame 203 and the upper end of the connecting piece 2046, and a limiting post 2048 fixedly connected to the inner cavity of the mounting block 2042. One end of the limiting post 2048 away from the inner wall of the mounting block 2042 extends through the inner cavity of the locking post 2044 and is slidably connected to its inner cavity.

[0036] like Figure 2 and 4 As shown, the push post 2043, the locking post 2044 and the locking groove 2045 cooperate to adopt a two-way locking mechanism to prevent lateral displacement. At the same time, it is also convenient to quickly install or disassemble the mounting bracket 202 and the limiting frame 203. The stainless steel compression spring 2047 provides a reference, and the limiting post 2048 ensures the stability of the movement trajectory of the locking post 2044.

[0037] In use, the mold body 103 is first placed between the two clamping plates 1051. The position of the right clamping plate 1051 is adjusted by rotating the threaded rod 1053, so that the two clamping plates 1051 can cooperate to clamp and fix the mold body 103. The interior of the mold body 103 is heated by heating wires. During use, the infrared thermal imager 104 can detect the temperature of various parts of the mold body 103. If any heating wire is damaged and cannot work properly, resulting in uneven temperature distribution inside the mold body 103, the infrared thermal imager will detect the problem. The infrared thermal imager 104 can provide thermal imaging, enabling staff to promptly detect mold damage for replacement or maintenance, ensuring uniform fluorine lining of valves. The infrared thermal imager 104 is easily disassembled. To disassemble it, first press the push column 2043, which, together with the connecting piece 2046, moves the locking column 2044 out of the slot 2045. After it is moved out, the positioning effect on the mounting block 2042 disappears, and the limit frame 203 can be removed from the top of the mounting bracket 202 by moving it upwards. After removal, the infrared thermal imager 104 can be taken off.
