[0003] For example, in order to effectively monitor the operating characteristics of equipment in real time, such as pressure, temperature, vibration and other characteristics, it is necessary to install multiple sets of sensor elements for monitoring. Often, in a small space, multiple sets of elements need to be led out. On the one hand, when arranging the wires, due to the large number and thin wires, the wires are arranged in a disordered manner, which is difficult to distinguish and is not conducive to subsequent repair and replacement. On the other hand, when some containers are undergoing operating characteristic testing, the internal space needs to remain sealed, and directly leading out the wires will also cause sealing problems. At the same time, the direct lead-out method will also result in poor insulation, which not only poses a safety hazard but is also not conducive to the monitoring function of the sensor's operating status.

[0040] Please refer to Figure 1-Figure 6 , Figure 1 It is a structural schematic diagram of the device body 1 in an embodiment of the present invention;

[0045] Figure 6 Schematic diagram of the connection between the sealing base 11 and the cooling jacket 15 in the embodiment of the present invention

[0046] An embodiment of the present application provides a multi-channel element sealing insulation device suitable for high temperature and high pressure conditions, which includes a device body 1. When in use, one end of the device body 1 is connected to the container, pipeline, reactor or other cavity to be measured by welding or other snap-on or threaded connection methods. Of course, it is connected to the interior of the cavity, and various sensors for monitoring are used to extend this device body 1 into the object to be measured, so as to achieve the purpose of monitoring the operating characteristics, and the other end of the various sensors extends from the other end of this device body 1 to connect a power supply or a controller, etc.

[0047] The device body 1 includes a mounting portion, a connecting portion and a lead-out portion which are connected in sequence. The mounting portion is used to connect to the container, pipeline, reactor or other cavity to be tested. The connection method can be welding or other buckling, threading, etc. Of course, the connection must have good sealing performance.

[0048] A single or multiple sleeve channels 2 are arranged inside the mounting part, the connecting part and the leading part, and the single or multiple sleeve channels 2 of the mounting part, the connecting part and the leading part are connected in sequence. That is, the sleeve channels 2 are passed through the mounting part, the connecting part and the leading part, and the function of the sleeve channels 2 is to insert the wires. For example, when the sensor is used to monitor the running characteristics, the connecting wires or signal lines of the sensor are extended from the sleeve channels 2 to the outside of the object to be measured, so as to achieve the monitoring function and realize the effect of the sensor.

[0049] When in use, the installation of the device body 1 is achieved by connecting the mounting portion to the object to be measured or other objects for use, and the connection method can be welding or other detachable connection methods. If the object connected to the device body 1 needs to maintain a sealed condition, the connection also needs to be sealed. When various electrical components need to be inserted into the object connected to the device body 1, the wires of the various electrical components are extended from the device body 1 to the outside of the object, and the wires extended to the outside are connected to the connection of the electrical components, that is, the sleeve channel 2 is used for the insertion of the wires, thereby avoiding the need to drill holes according to the number of wires during wiring, and the connection between the wires and the threading holes is not necessary. The sealing between the inner walls is difficult to handle, which makes it difficult to operate when it is necessary to maintain the sealing conditions inside the object; and for the arrangement of the wires of various electrical components, the sleeve channel 2 running through the device body 1 is utilized to allow the connecting wires to pass through the sleeve channel 2, so that the arrangement of the connecting wires will not be disordered, and whether it is during later maintenance or overhaul and replacement, the source of each wire can be quickly distinguished, so that the maintenance or overhaul process is convenient and quick; and the wires are led out through the device body 1, so that the insulation performance between each wire and between the wire and the object is greatly improved, reducing safety hazards and making the sensor monitoring more accurate.

[0050] Especially under the condition of high temperature and high pressure, the use of the device body 1 can make the installation and monitoring under such conditions more secure.

[0051] The number of sleeve channels 2 is generally determined by the number of wires that need to pass through, and the diameter of each sleeve channel 2 is also determined according to the diameter of the wire or actual usage. When the device body 1 is mass-produced, device bodies 1 with different numbers of sleeve channels 2 and different diameters of sleeve channels 2 can be produced to meet actual usage requirements.

[0052] In actual use, the number of wires plugged into each casing channel 2 is also determined according to actual conditions, and can be one, two or even more. Of course, when arranging the wires, as long as it does not affect subsequent maintenance and inspection and the source of each wire can be quickly identified, the number of wires in each casing channel 2 can be flexibly handled.

[0054] In this embodiment, the above-mentioned installation part includes a pipe 5 pressure cap 3 and an external base 4 movably connected to the inner wall of the pipe 5 pressure cap 3; that is, the installation part is composed of two parts including the pipe 5 pressure cap 3 and the external base 4, and the external base 4 is plugged into the pipe 5 pressure cap 3. When in use, the end of the external base 4 is connected to the object to be installed by welding or other connection methods, and when a threaded connection is adopted, the outer wall of the external base 4 can be provided with an external thread or an internal thread.

[0055] One end of the pipe 5 pressure cap 3 is detachably connected to the connection part, and the other end of the pipe 5 pressure cap 3 is threadedly matched with the external base 4. That is, the pipe 5 pressure cap 3 is provided with an internal thread, and the external base 4 is provided with an external thread, and the two are used in combination. Of course, the connection between the pipe 5 pressure cap 3 and the external base 4 can also be other connection methods, such as a buckle connection.

[0058] One end of the pipe 5 is fixedly connected to the lead-out portion, which may be welded or connected in other ways, such as threads; the other end extends into the pipe 5 pressure cap 3, and there is a limiting structure between the pipe 5 and the pipe 5 pressure cap 3, so that after the pipe 5 is connected to the pipe 5 pressure cap 3, it can extend from one end of the pipe 5 pressure cap 3, and the other end is prevented from being separated by the limiting structure, and this end is also abutted against the end of the external base 4, and the end of the insulating sleeve 6 extending from the pipe 5 extends into the external base 4; Figure 2 The above-mentioned sleeve channel 2 passes through the insulating sleeve 6.

[0059] In this embodiment, the end of the pipe 5 extends outward to form a limiting portion 7; the inner wall of the pipe 5 pressure cap 3 extends inward to form a limiting ring 8 that abuts against the limiting portion 7. The limiting ring 8 and the limiting portion 7 constitute the above-mentioned limiting structure. Figure 1 and Figure 2 As shown, after one end of the pipe 5 extends into the pipe 5 pressure cap 3, the limiting portion 7 abuts against the limiting ring 8, so that the two cannot be separated, thereby making the connection between the mounting portion and the connecting portion more stable.

[0060] In this embodiment, the end of the limiting portion 7 is provided with an arc convex surface 9, and the end of the external base 4 is provided with an arc concave surface abutting against the arc convex surface 9. Figure 1 and Figure 2 That is, after the connecting pipe 5 extends into the interior of the connecting pipe 5 pressure cap 3, the limiting portion 7 abuts against the limiting ring 8, and the end of the limiting portion 7 also abuts against the end of the external base 4, that is, through the abutment relationship between the arc convex surface 9 and the arc concave surface, the connection between the two is more stable, and the sealing effect is also more significant.

[0064] The outlet portion is also provided with sealing components from the outside to the inside, the interior of the sealing components is communicated with the interior of the insulating sleeve 6 , and the number of the sealing components corresponds to the number of the sleeve channels 2 .

[0065] Example 5

[0066] In this embodiment, the sealing assembly includes a secondary sealing pressure cap 12, a secondary sealing filler block 13 and a primary sealing filler block 14 which are connected in sequence; the interior of the sealing assembly is connected to the interior of the insulating sleeve 6, that is, it is connected to the sleeve channel 2 of the insulating sleeve 6, that is, the secondary sealing pressure cap 12, the secondary sealing filler block 13 and the primary sealing filler block 14 are all penetrated by corresponding and connected through holes, and the through holes of each group of sealing assemblies correspond to and are connected to each sleeve channel 2.

[0067] The structure of the sealing component is as follows Figure 3-Figure 5 As shown, the secondary sealing pressure cap 12 is plugged with the primary sealing pressure cap 10, and the secondary sealing filler block 13 and the primary sealing filler block 14 are located inside the sealing base 11, and the primary sealing filler block 14 is plugged with the sealing base 11, and there is a limit mechanism between the two, so that the primary sealing filler block 14 can not drop further after it extends into the sealing base 11 and drops to a certain position, and there is a filling cavity composed of boron nitride inside the sealing base 11, and this filling cavity is connected and corresponds to a single or multiple sleeve channels 2 and the inside of the sealing component, so that the wires will not be damaged when they are inserted.

[0068] The end of the first-level sealing pressure cap 10 is penetrated by a screw hole that is threadedly matched with the second-level sealing pressure cap 12; one end of the first-level sealing filler block 14 extends into the sealing base 11, and the other end abuts against the end of the second-level sealing filler block 13; one end of the second-level sealing pressure cap 12 extends into the interior of the first-level sealing pressure cap 10 and abuts against the other end of the second-level sealing filler block 13.

[0069] That is to say, when the secondary sealing cap 12 is connected to the primary sealing cap 10, it is connected by a threaded connection, such as Figure 2 As shown, the end of the secondary sealing cap 12 extending into the interior of the primary sealing cap 10 is abutted against one end of the secondary sealing stuffing block 13, and one end of the secondary sealing stuffing block 13 is abutted against one end of the primary sealing stuffing block 14, and the other end of the primary sealing stuffing block 14 extends into the above-mentioned filling cavity composed of boron nitride, and as mentioned above, there is a limiting structure, so after the secondary sealing cap 12 is connected to the primary sealing cap 10, and then the primary sealing cap 10 is screwed together with the sealing base 11 through threads, the connection positions of the secondary sealing cap 12, the secondary sealing stuffing block 13 and the primary sealing stuffing block 14 will be precisely combined, thereby greatly improving the sealing effect.
