[0026] Currently, there is a problem of poor sealing between the existing pipe sleeve and the connecting hole on the shell.

[0027] In order to solve the above problems, the utility model provides a temperature sensing wire nozzle. Figure 1 to Figure 2 The utility model provides a specific embodiment of the temperature sensing wire nozzle.

[0028] See also Figure 1 to Figure 2 The temperature sensing line nozzle 100 includes: a mounting seat 1, a pipe sleeve 2 and a sealing assembly 3. The mounting seat 1 has a mounting channel 11 formed therein, and the mounting seat 1 is used to be mounted on a housing 210 of a PVC board production device; the pipe sleeve 2 is installed in the mounting channel 11, and the pipe sleeve 2 is used for the temperature sensing line to pass through; the sealing assembly 3 is arranged in the mounting channel 11 and is surrounded by the outer periphery of the pipe sleeve 2 to block the gap between the pipe sleeve 2 and the mounting channel 11.

[0029] The mounting seat 1 is installed at the connecting hole on the shell 210 of the PVC board production equipment. A mounting channel 11 is set at the center position of the mounting seat 1. The mounting channel 11 is used for the pipe sleeve 2 to pass through. The inside of the pipe sleeve 2 is used for the installation and placement of the temperature sensing line. Because the chamber of the PVC board production equipment 200 is filled with liquid, the temperature sensing line cannot be directly extended into the chamber, and a pipe sleeve 2 needs to be put on the outside of the temperature sensing line. Because it is convenient for the pipe sleeve 2 to be installed in the mounting channel 11, the diameter of the mounting channel 11 is larger than the diameter of the pipe sleeve 2. Therefore, when the pipe sleeve 2 is installed in the mounting channel 11, there is a gap between the pipe sleeve 2 and the mounting channel 11. In order to ensure that the mounting channel 11 can be sealed after the pipe sleeve 2 is installed, a sealing component 3 is set at the mounting channel 11. The sealing component 3 is arranged in the mounting channel 11 and is located on the outer peripheral side of the pipe sleeve 2 to block the gap between the pipe sleeve 2 and the mounting channel 11, thereby achieving a sealing effect. The sealing assembly 3 includes a sealing member 31 for sealing and other components acting on the sealing member 31 to exert pressure or fix the sealing member 31. The sealing member 31 is generally a rubber member, a plastic member or a metal member, which can fit tightly with the installation channel 11 and the pipe sleeve 2 and is not air-permeable.

[0030] The functions of the temperature sensing wire nozzle 100 are, on the one hand, to seal the space around the pipe sleeve 2, and on the other hand, to fix the pipe sleeve 2 to prevent the pipe sleeve 2 from shaking significantly.

[0031] In order to improve the sealing effect of the sealing assembly 3, the mounting seat 1 has a first side 12 and a second side 13 that are relatively arranged. The first side 12 is used to be installed toward the PVC board production equipment housing 210. In the direction from the first side 12 toward the second side 13, the width of the mounting channel 11 is at least partially gradually increased. Correspondingly, the sealing assembly 3 includes a sealing member 31. The width of the sealing member 31 is gradually increased corresponding to the mounting channel 11. During the process of the pipe sleeve 2 passing through the sealing member 31, there is friction between the pipe sleeve 2 and the sealing member 31. The friction drives the sealing member 31 to move from the second side 13 toward the first side 12. Since the cross-section of the sealing member 31 is wedge-shaped, under the action of friction, the seal 31 and the mounting channel 11 fit more and more tightly, thereby preventing gas from passing through and achieving a better sealing effect. The width of the installation channel 11 is at least partially gradually increased, and the width of the entire installation channel 11 can be gradually increased, or the width of a part of the installation channel 11 can be gradually increased. In order to facilitate installation, the part with gradually changed width is set at the end of the installation channel 11. One end of the installation channel 11 can be set to have a gradually changed width, or both ends can be set to have a gradually changed width. The choice can be made according to the sealing effect. If the width of the end of the installation channel 11 close to the first side 12 of the mounting seat 1 is also gradually increased, then the seal 31 installed there may fall off the installation channel 11 due to the friction between the pipe sleeve 2 and the seal 31 during the installation of the pipe sleeve 2. Therefore, generally only the end of the installation channel 11 close to the second side 13 is set with a gradually changed width installation channel 11. If it is necessary to set the end of the installation channel 11 close to the first side 12 with a gradually changed width installation channel 11, a fixing device is also required to fix the seal 31. In addition, a plurality of grooves can be set in the installation channel 11, and a plurality of bosses are correspondingly set on the seal 31. The bosses are engaged in the grooves to increase the sealing performance in turn.

[0032] In addition, the seal 31 has a through hole that passes through the first side and the second side in relative directions for the pipe sleeve 2 to pass through. Generally, the diameter of the through hole is larger than the diameter of the pipe sleeve 2, but such a setting has poor sealing performance. Therefore, when the diameter of the through hole is slightly smaller than the diameter of the pipe sleeve 2, if the seal 31 is rigid, the pipe sleeve 2 cannot pass through the through hole. Therefore, the seal 31 is elastically configured so that the pipe sleeve 2 can pass through the through hole. Moreover, after the through hole is passed through, under the elastic action of the seal 31 itself, the inner wall of the through hole is tightly attached to the pipe sleeve 2, and a certain pressure is generated between them, thereby achieving better sealing performance. In addition, when the seal 31 moves toward the first side 12 under the action of friction, the elastic seal 31 moves to a region with a smaller pipe diameter. The greater the compression, the greater the pressure between the seal 31 and the mounting seat 1 and the pipe sleeve 2, so that the seal 31 and the mounting seat 1 and the pipe sleeve 2 fit more tightly, so that a better sealing effect can be achieved. The seal 31 is generally made of rubber. On the one hand, the solid rubber has good elasticity, is airtight and has good sealing performance. In addition, the rubber itself has a large friction coefficient. Therefore, the greater the friction between the pipe sleeve 2 and the seal 31, the greater the friction the seal 31 is subjected to and the more it moves into the narrow space, thereby increasing the deformation amount, making the seal 31 fit more tightly with the mounting seat 1 and the pipe sleeve 2. The rubber seal 31 has a table shape and has a through hole that runs axially along the central axis.

[0033] In order to apply pressure on the seal 31 from the first side 12 toward the second side 13, thereby increasing the compression of the seal 31 and increasing the pressure between the seal 31 and the mounting seat 1 and the pipe sleeve 2, and making the fit between them tighter, the sealing assembly 3 also includes a pressing piece 32, which is used to press the seal 31 toward the first side 12 of the mounting seat 1.

[0034] Specifically, the pressed part 32 is a cover 321, which is movably arranged on the second side 13 of the mounting seat 1 along the relative direction between the first side and the second side, and the cover 321 is provided with an internal thread, and the mounting seat 1 is correspondingly provided with an external thread, and the cover 321 is threadedly connected with the mounting seat 1. On the one hand, the threaded connection can realize the application of pressure in the direction from the first side 12 to the second side 13, and on the other hand, the rotation of the control value thread can change the magnitude of the applied pressure, thereby controlling the magnitude of the deformation, and further controlling the sealing effect between the sealing member 31 and the mounting seat 1 and the pipe sleeve 2.

[0035] In addition, both the internal and external threads are set as coarse threads. Compared with fine threads, coarse threads have a deeper depth, which makes the sealing between the cover 321 and the mounting seat 1 better. The fine threads have a disadvantage that they are easier to slip than coarse threads (although the tensile strength of fine-thread bolts of the same diameter is higher than that of coarse threads). In other words, coarse threads are not easily damaged and have a greater connection strength. Coarse threads are easier to disassemble and assemble than fine threads. In order to prevent the cover 321 from loosening and causing the pressure on the seal 31 to decrease, thread tightening glue can also be applied to the threaded connection between the cover 321 and the mounting seat 1.

[0036] Because the seal 31 is installed inside the installation channel 11, the cover 321 at least partially needs to extend into the installation channel 11 to press the seal 31. The cover 321 is protruding in the direction toward the first side 12 to form a pressing portion 3211. The pressing portion 3211 is an annular boss, which is used to abut against one side of the seal 31 in the opposite direction of the first side and the second side. The pressing member 32 and the cover 321 can also be connected by a snap-on connection. The cover 321 is provided with a sub-snap, and the mounting seat 1 is provided with a plurality of female snaps. The sub-snap cooperates with different female snaps, and the acting forces between the pressing portion 3211 and the seal 31 are different.

[0037] In order to allow the pipe sleeve 2 to extend into the installation channel 11, a mounting hole 3212 is required to be provided on the cover body 321, which is arranged to pass through the first side and the second side in opposite directions. The pipe sleeve 2 is first penetrated by the mounting hole 3212 and then by the installation channel 11. In order to further improve the sealing performance, a sealing ring is provided in the mounting hole 3212, and the sealing ring is fitted and abutted against the outer peripheral side of the pipe sleeve 2.

[0038] In order to install temperature sensing wires of different sizes, the diameter of the pipe sleeve 2 will change. In order to adapt to different pipe sleeves 2, multiple mounting seats 1 are also correspondingly provided. The minimum apertures between the mounting channels 11 of the multiple mounting seats 1 are different, so pipe sleeves 2 of different sizes are installed.

[0039] In addition, the utility model provides a PVC board production equipment 200, the PVC board production equipment 200 includes: a temperature sensing line nozzle 100 and a shell 210, the shell 210 includes a connecting hole, and the temperature sensing line nozzle 100 is fixedly installed in the connecting hole. The temperature sensing line nozzle 100 includes: a mounting seat 1, a pipe sleeve 2 and a sealing component 3, the mounting seat 1 has a mounting channel 11 formed therein, and the mounting seat 1 is used to be installed on the PVC board production equipment shell 210; the pipe sleeve 2 is installed in the mounting channel 11, and the pipe sleeve 2 is used for the temperature sensing line to pass through; and the sealing component 3 is arranged in the mounting channel 11 and is surrounded by the outer periphery of the pipe sleeve 2 to block the gap between the pipe sleeve 2 and the mounting channel 11.

[0040] The temperature sensing wire nozzle 100 is fixedly mounted on the communication hole, and the mounting seat 1 extends in the circumferential direction to form an extension portion, which abuts against one side of the housing 210, and the extension portion and the housing 210 are bonded, or the mounting seat 1 and the communication hole are threadedly connected to ensure the sealing between the communication hole and the mounting seat 1. In order to prevent the sealing between the mounting seat 1 and the housing 210 from being poor, a sealing ring can also be provided in the communication hole.
