Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0031] like Figures 1 to 5 As shown, the utility model provides a thermocouple penetration device, including a connecting mechanism 1 and a sealing mechanism 2; the connecting mechanism 1 includes a first connecting component and a second connecting component, one end of the first connecting component is connected to a container 4 to be tested, and the other end is connected to the second connecting component, a thermocouple 3 in the container 4 to be tested passes through the first connecting component and the second connecting component in sequence, and the sealing mechanism 2 is installed on the second connecting component for fixing the thermocouple 3 and sealing the first connecting component and the second connecting component.

[0032] In this embodiment, the first connecting component is directly connected to the container 4 to be tested, and the first connecting component is directly connected to the second connecting component. After the thermocouple 3 directly passes through the first connecting component and the second connecting component, the thermocouple 3 is fixed by the sealing mechanism 2 connected to the second mounting component, and the second connecting component is sealed, so that multiple thermocouples 3 can be concentratedly penetrated, and the first connecting component and the second connecting component after the thermocouples are penetrated are sealed, thereby ensuring the sealing of the container 4 to be tested.

[0033] Since the thermocouple 3 directly penetrates the first connecting component and the second connecting component and is sealed by the sealing mechanism 2, the material of the thermocouple 3 itself is not changed, and no termination material is added in the middle, which will not cause deviation in the signal output.

[0034] The thermocouple 3 itself can withstand high temperatures. The thermocouple penetration device provided in this embodiment can also effectively ensure the sealing of the container 4 to be tested under the action of the sealing mechanism 2, so it can complete the measurement of high-temperature and high-pressure container equipment.

[0035] According to an embodiment provided by the utility model, Figure 1 and Figure 5 As shown, the first connection assembly includes a connection pipe 101 and a fixed flange 102. One end of the connection pipe 101 is fixed on the container to be tested 4 for the thermocouple 3 to pass through. The other end of the connection pipe 101 is connected to the fixed flange 102, and the fixed flange 102 is used to connect to the second connection assembly.

[0036] Furthermore, the second connection assembly includes a blind flange 103 matching the fixed flange 102 . The blind flange 103 is connected to the fixed flange 102 and fixed by bolts 104 .

When maintenance is needed at a later stage, the thermocouple 3 can be directly disassembled and replaced. Replacing the thermocouple 3 will not affect the sealing performance of the sealing mechanism 2, so that the thermocouple penetration device provided in this embodiment can be used repeatedly to extend the service life.

[0038] According to an embodiment provided by the utility model, Figure 1 As shown, a flange gasket 105 is provided between the blind flange 103 and the fixed flange 102 .

Conventional thermocouple 3 compensation wires are connected to the outside of the single-hole and multi-porous seals. There is no transition material in the middle of the penetration device, which has no effect on the signal.

[0042] Preferably, the porous sealing component 202 can select the number of holes of the sealing component according to the number of thermocouples 3 penetrated. The single-hole sealing component 201 is suitable for thermocouples 3 with a diameter greater than 3 mm, and is penetrated separately; the porous sealing component 202 is suitable for thermocouples 3 with a diameter less than 2 mm, and is penetrated from the same position for measuring multiple temperatures. In addition, the corresponding seal can also be selected according to the diameter of the thermocouple 3 wire, so the thermocouple penetration device provided in this embodiment can be applicable to thermocouples 3 of various sizes, and has good overall applicability.

[0043] Among them, the porous sealing component 202 can also be installed independently, which is suitable for dispersing and penetrating several thermocouples 3 to the outside of the container 4 to be tested, and penetrating from multiple sides on the same device; the single-hole sealing component 201 is also suitable for a single thermocouple 3.

The fastening nut 204 is threadedly matched with the second screw hole and fixed on the blind flange 103 , and the sealing nut 205 is fixed on the fastening nut 204 .

[0052] In this embodiment, the porous sealing assembly 202 includes a fastening nut 204 and a sealing nut 205.
