Reconstruction method of cable joint of induction melting furnace
In the prior art, the connection between the cable and the induction coil is a flange connection (see Figure 2). The copper tube on the inductor is welded to the copper flange. The copper flange is grooved to add sealing filler during assembly. Keep it from leaking. The shape of the cable connector is exactly the same. Add sealing packing during assembly, and connect two flanges with stainless steel bolts. Its disadvantages are: high requirements for processing and welding assembly, easy to leak, inconvenient assembly and maintenance, and not suitable for high-power power supply.
Summary of the Invention
A cable connector body in a coreless induction melting furnace in which a compression nut and a cable connector are screwed together. Authentic
Use a new technical solution: its structure is composed of a compression nut, a compression ring, a sealing ring, and a cable connector. The compression nut is screwed with the fine teeth of the cable connector. The utility model has the advantages that the structure is simple, reasonable, novel, and the way in which the compression nut and the cable joint are connected by threads is reliable and safe. When the nut is tightened, the compression force of the pressure ring and the cable connector causes the copper seal ring to deform. The two sides of the seal ring are closely attached to the sensor tube wall, which effectively prevents water leakage. The use of power supply greatly improves the efficiency of use.
In the figure, 1 is a compression nut, 2 is a compression ring, 3 is a sealing ring, 4 is a cable connector, and 5 is an induction
The connector is connected to a copper pipe, 6 is a copper flange, and 7 is welding.
