The invention can be popularized to more occasions that the inner part of the container needs to be connected by the sleeve and the insertion depth needs to be adjusted.
Background
In some needs use the occasion of running through formula sleeve pipe thermocouple, the sealed mode of cutting ferrule can be adopted usually in running through of thermocouple, and traditional cutting ferrule sealed mode often need with copper hoop cooperation fixation nut assemble fixed, the copper hoop is the cover on the thermocouple runs through the sleeve pipe, places moreover between fixation nut and double thread cutting ferrule, through fixation nut's continuous extrusion, the copper hoop can block and die in the gap between fixation nut and double thread cutting ferrule. Although the firmness of the penetrating piece is greatly guaranteed through assembly and fixation in the mode, the penetrating piece cannot be punched out by internal pressure, the insertion depth of a sleeve of the penetrating piece cannot be adjusted, the difficulty in changing the position of the thermocouple and the temperature measuring position is greatly increased, and therefore the penetrating piece of the thermocouple cannot be reused and is extremely waste. Therefore, the problems that the pressure bearing performance and the sealing performance of the thermocouple penetration piece can be guaranteed, the penetration piece sleeve insertion depth can be adjusted, and the penetration piece sleeve can be detached and reused need to be solved.
In the known thermocouple penetration designs, the insertion depth of the thermocouple penetrations cannot be adjusted in multiple stages so that the installation position of the temperature measuring point cannot be changed. For example, in some patents (patent application No. 201120083335.6; patent application No. 200520022884.7; patent application No. 03157054.2; patent application No. 201821199232.4), these penetrations are relatively complex in structure, more cumbersome to assemble and disassemble, relatively demanding in terms of manufacturing process, unsuitable for a wide range of applications, incapable of adjusting the insertion depth in multiple stages to change the mounting position of the temperature measurement point, and relatively less versatile.
In the patent (patent application No. 201210540284.4), the method of connection and fixation according to the pressure difference in the invention thereof also makes the processing and installation more troublesome, and it cannot adjust the insertion depth of each thermocouple, and does not facilitate the change of the temperature measuring position. In the patent (patent application No. 200310113570.3), the invention is more suitable for large-volume containers, the inner and outer sets of nut threads are required to be fixed together, the structure is more complex, the universality is poorer, and the disassembly is more troublesome.

Connect base 4 and be perforation N type structure through laser or argon arc welding, can make like this connect base and two screw thread cutting ferrule through the mode of extrusion around with the extrusion of semicircle annular gasket inseparabler, more firm.
Detachable semicircle annular gasket 5 is also one of this design bright spot, and semicircle annular gasket is from taking a recess and tongue for fixed complete ring shape gasket that forms, and this complete ring shape gasket can run through sheathed tube recess concave-convex department with suitable thickness and closely cooperate, can guarantee its reliability and fastness, can guarantee its convenience and reuse nature again.
In the whole design, the thermocouple is extremely simple to install after penetrating through the sleeve, the thermocouple is installed only by welding the connecting base firstly, inserting the thermocouple sleeve with one end matched with the two semicircular gaskets and the other end wound by a sufficient amount of raw materials, screwing the double-thread clamping sleeve and finally screwing the fixing nut. The device is well applicable to containers with various volumes, good in universality, simple to process and low in cost. When the thermocouple penetrates through the sleeve, the fixing nut and the clamping sleeve are required to be sequentially screwed off, and then the thermocouple penetrates through the sleeve and is taken down together with the circular gasket which is matched together, so that the thermocouple is also very convenient to disassemble.
The thermocouple can be used for placing a plurality of thermocouples through the sleeve.
The thermocouple penetrating sleeve is installed from the outside of the container to the inside of the container, the thermocouple penetrating sleeve is installed by welding the connecting base, inserting the thermocouple penetrating sleeve with one end matched with the two semicircular gaskets and the other end wound with enough raw material, screwing the double-thread clamping sleeve and finally screwing the fixing nut. The installation is simple and convenient, and the container of all kinds of volumes can be well suitable.
The thermocouple runs through the sleeve pipe and dismantles easily, when dismantling the thermocouple and run through the sleeve pipe, only need to unscrew fixation nut 2, double thread cutting ferrule 3 in proper order, runs through the sleeve pipe again the thermocouple and takes off with the ring gasket who cooperates together, it is very convenient to dismantle.
The one end of two screw thread cutting ferrule has the external screw thread, can extrude two semicircle annular gaskets well, makes more inseparabler of its laminating, and the other end has internal thread and bottom to be circular-arcly, and at the in-process that fixation nut twisted, bottom circular arc and fixation nut cooperation for it is inseparable with the extrusion of sleeve pipe recess to twine the raw material area of affixing to on the sleeve pipe, thereby has increased the thermocouple better and has run through sheathed tube leakproofness and pressure-bearing nature.
