Detailed description of the invention
Embodiment
As Figure 1-4.A kind of stuck-module for installing dew end formula thermocouple, includes a cylinder 1, and the front end outer wall of cylinder 1 is provided with external screw thread 2；The processing of cylinder 1 axial centre front end has the interior hexagonal screw 3 of certain depth, to be convenient to stuck-module with inner hexagon spanner from the installation the installation of TC device and dismounting, the other end processing of cylinder 1 axial centre has thermocouple wire to fix groove 4, the fixing groove 4 of thermocouple wire be mounting hole, and thermocouple wire fixes the equal chamfering in edge of groove 4 and width and length and selected thermocouple wire 7 diameter matches；On the fixing groove 4 of thermocouple wire, reprocessing half ball 5 is used for fixing thermocouple measurement ball 8, and half ball 5 diameter and selected thermocouple diameter match；In in cylinder 1, between hexagonal screw 3 and the fixing groove 4 of thermocouple wire, processing vertically has an internal thread hole 6；Thermocouple wire 7 is drawn after sequentially passing through half ball 5, thermocouple wire fixing groove 4, internal thread hole 6, interior hexagonal screw 3, until thermocouple measurement ball 8 matches with half ball 5.
Thermocouple is combined with the installation of TC device, and the installation of TC device digs the tapped flat counterbore of certain depth, and tapped flat counterbore matches with the external screw thread 2 of cylinder 1, for stuck-module is fixed on the installation of TC device.
Cylinder 1 material is consistent with the material of the installation of TC device.
The internal thread hole 6 of cylinder 1 is installed an earthenware 9, earthenware 9 has two through holes vertically, for two thermocouple wires 7 are separated and insulate.
During installation, two thermocouple wires 7 to separate, in the fixing groove 4 of the thermocouple wire of parallel insertion, owing to the width of the fixing groove 4 of thermocouple wire is suitable with wire 7 diameter, it is ensured that rotation stuck-module time, wire will not be wound around.After the fixing groove 4 of thermocouple wire, the two of thermocouple wires are had through centre the earthenware 9 in two holes, makes two wire insulations, then carry out the insulation of the thermocouple wire after passing earthenware again with insulant such as glass fiber sleeve pipes (or similar).
The stuck-module installing thermocouple as shown in Figure 4 is mounted in device under test.First being inserted in the interior hexagonal screw of stuck-module at the inner hexagon spanner opening thermocouple wire guide groove, thermocouple wire traverse guide channel is made during insertion, it is prevented that during rotation, operate thermocouple wire and insulating barrier.Stop when rotating inner hexagon spanner to the bottom surface close contact of thermocouple temperature measurement ball and flat counterbore, owing to the material of stuck-module and the material of device under test are identical, therefore the coefficient of expansion is consistent when variations in temperature, the occlusion of screw thread simultaneously, the fixing of the thermocouple made has certain elasticity, makes the fixing relatively reliable of thermocouple.
