It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
as shown in fig. 1, 4 and 5, embodiment 1 of the present invention provides a structure of a joint for a low-temperature test of a sintering furnace for temperature detection during assembly of a temperature thermocouple, including a pipe joint 2 having a first end disposed at a sintering furnace interface 1, a first through hole 3 and a second through hole 4 disposed in the pipe joint 2 and communicating with each other and penetrating both ends thereof, a first sealing structure disposed in the second through hole 4, and a plurality of through holes disposed on the first sealing structure for allowing the temperature thermocouple 5 to pass therethrough. After the temperature thermocouple 5 is completely installed in place, the first sealing structure can seal the gap between the temperature thermocouple 5 and the side wall of the second through hole 4, so that the sealing performance of the whole sintering furnace interface 1 is ensured, and the temperature in the furnace is prevented from generating obvious change. The probes of the temperature thermocouple 5 penetrate through the first through hole 3 to enter the sintering furnace, and the temperature measurement of each space position in the furnace can be completed by respectively adjusting the extending amount of different probes. In addition, a blocking sleeve 13 is movably arranged at the second end of the pipe joint 2, the outer end wire of the temperature thermocouple 5 penetrates through the blocking sleeve 13 to be connected with other equipment, and a second sealing structure arranged between the pipe joint 2 and the blocking sleeve 13 is removed during temperature measurement.
The aperture of the first through hole 3 is smaller than that of the second through hole 4, a first step 6 is formed at the connecting transition position of the first through hole 3 and the second through hole 4, and the outer diameter of the first sealing structure corresponds to that of the second through hole 4 and is larger than that of the first through hole 3, so that the first sealing structure is limited by the first step 6 and cannot enter the first through hole 3. Specifically, the first sealing structure includes a porous sealing gasket 7 made of rubber, and a plurality of first through holes 8 penetrating through two ends of the porous sealing gasket 7 are formed in the porous sealing gasket 7. In this embodiment, the outer side wall of the porous sealing gasket 7 is in transition fit with the second through hole 4, and the first through hole 8 is in transition fit with the temperature thermocouple 5, so that the porous sealing gasket 7 in the temperature measurement state is tightly attached to the inner side wall of the second through hole 4 and the temperature thermocouple 5 due to elastic extrusion, and the sealing state of the whole second through hole 4 is formed.
Further, first seal structure still includes a porous gasket 9, has seted up a plurality of second perforation 10 with first perforation 8 one-to-one on the porous gasket 9, and the lateral wall of porous gasket 9 is interference fit with first through-hole 3, and porous gasket 9 is located the innermost side of second through-hole 4, contacts with first step 6. In this embodiment, the porous gasket 9 is made of 304 steel, and has sufficient hardness, so that the porous gasket 9 is not deformed when the porous gasket 7 moves and presses toward the first step 6, and the end portion of the porous gasket 7 made of rubber is prevented from being deformed due to direct contact between the porous gasket 7 and the first step 6. Because the porous gasket 9 is also provided with the second through holes 10, the first through holes 8 are extended by a certain length, so that the temperature thermocouples 5 can be well fixed and oriented, and a plurality of temperature thermocouples 5 cannot be knotted in the same sintering furnace joint 1.
In the present embodiment, the first end and the second end of the pipe joint 2 are both provided with external threads 11, and the pipe joint 2 is screwed with the sintering furnace interface 1 through the external threads 11 of the first end, as shown in fig. 5. Meanwhile, a first annular sealing ring 12 is arranged at the joint for further sealing the pipe joint 2 and the sintering furnace interface 1. A third through hole 14 and a fourth through hole 15 which are communicated with each other are arranged in the blocking sleeve 13, wherein an inner side wall of the third through hole 14 is provided with an inner thread 16, and the blocking sleeve 13 is sleeved in the second end of the pipe joint 2 and is movably and detachably connected with the outer thread 11 at the second end of the pipe joint 2 through the inner thread 16 of the third through hole 14.
In addition, the first sealing structure further comprises a cylindrical bushing 17 which is arranged in the second through hole 4 in a clearance fit manner, and a first end of the bushing 17 is in contact with the porous sealing gasket 7 and a second end is in contact with the blocking sleeve 13. Therefore, when the blocking sleeve 13 moves inwards in a spiral mode, the lining 17 can be pushed towards the bottom end of the second through hole 4 in a squeezing mode, the porous sealing gasket 7 and the porous gasket 9 are attached to the bottom end of the second through hole 4 in sequence and limited by the first step 6, and a fixed and sealed state is formed. Wherein the bushing 17 has a sufficient length such that the bushing 17 still extends out of the second end position of the pipe joint 2 after the porous sealing gasket 7 and the porous gasket 9 are stopped by the first step 6.
In this embodiment, the aperture of the third through hole 14 of the retaining sleeve 13 is larger than the aperture of the fourth through hole 15, so that a second step 18 is formed at the connection transition position of the third through hole 14 and the fourth through hole 15, the pushing force is provided by the spiral displacement of the bushing 17 by the contact of the side wall of the second step 18 and the end of the bushing 17.
Example 2:
as shown in fig. 2, embodiment 2 of the present invention provides another structure of a joint for a low temperature test of a sintering furnace for assembling a temperature thermocouple for temperature detection, which is mainly different from embodiment 1 in that the first sealing structure is a porous sealing column 19, which is also made of rubber and is provided with a plurality of first through holes 8 penetrating through two ends, and the outer side wall of the porous sealing column 19 is in transition fit with the second through hole 4, and the first through holes 8 and the temperature thermocouple 5.

Therefore, the position of the porous sealing column 19 in the second through hole 4 can be adjusted by changing the spiral displacement of the baffle sleeve 13, and the extending amount of the probe of the temperature thermocouple 5 can be integrally adjusted. Moreover, since the porous sealing post 19 is provided long enough, the thermo-element 5 can be oriented better, ensuring that it does not get tangled.
Example 3:
embodiment 3 of the present invention provides a structure that is sealed when the temperature thermocouple is not assembled in the joint for the low temperature test of the sintering furnace, and as shown in fig. 3, a second sealing structure is provided between the pipe joint 2 and the spacer sleeve 13 to seal the second end of the pipe joint 2. In particular, the second sealing means comprise a sealing gasket 20 arranged in the third through hole 14 of the retaining sleeve 13 and a second annular sealing ring 21 arranged in an annular groove formed at the second end of the coupling 2. When the blocking sleeve 13 is spirally displaced towards the pipe joint 2, the sealing gasket 20 is in pressing contact with the second annular sealing ring 21 under the extrusion action of the second step 18 to form a sealing state, so that the second end of the pipe joint 2 is completely sealed through the matching action of the sealing gasket 20 and the second annular sealing ring 21, and the sealing degree of the sintering furnace in the use state without temperature measurement is ensured.
Therefore, when the temperature measurement is not needed, the spacer sleeve 13 is unscrewed after all the temperature measuring thermocouples 5 are directly taken out, the bushing 17 or the porous sealing column 19 is taken out, the sealing gasket 20 and the second annular sealing ring 21 are assembled at the corresponding positions, and finally the spacer sleeve 13 is re-assembled and screwed, so that the conversion between temperature measurement and non-temperature measurement can be realized without disassembling the whole joint, the assembly is simple, and the conversion efficiency is high.
In any of the above embodiments, the number of the openings is preferably 6, that is, the present invention can be simultaneously equipped with 6 temperature thermocouples 5.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
