Abstract

The utility model discloses a connecting sleeve of a water-cooling contact tube, which comprises a sleeve, a conical ring, nuts and sealing rings made of rubber. A conical surface is disposed on the outer side of an inner wall of the sleeve, the conical ring can be in rabbet joint with the conical surface, the nuts compressing the conical ring inwards along the conical surface are sleeved at two ends of the sleeve, two grooves are disposed in the middle of the inner wall of the sleeve along the peripheral direction, and the sealing rings are embedded in the grooves in an interference manner. The connecting sleeve of the water-cooling contact tube adopts the conical ring, the conical surface increases contact area of a conductor, accordingly conduction loss is reduced, sealing performance of the connecting sleeve is guaranteed by the aid of interference fit of the rubber sealing rings with the connected contact tube, the connecting sleeve of the water-cooling contact tube is simple and reliable, and the sleeve and the conical ring which are made of T2 red copper also reduce conduction loss.

Description

Water-cooled contact tube adapter sleeve

Technical field

The utility model relates to a kind of parts of metallurgical equipment, relates in particular to a kind of water-cooled contact tube adapter sleeve.

Background technology

The adapter sleeve of tradition metallurgical equipment is various informative, as utilizing the adapter sleeve that in the short net of the big electric current of ore furnace secondary, uses, wherein the contact-making surface between the electric conductor is a cylinder, contact area is less, make pick-up current density cause certain electrical loss more greatly, some adapter sleeve is to come airtight water route by the strain of electric conductor, but adopt this mode not only high to the requirement on machining accuracy of part, and useful life is short, especially it is extremely low to adopt the metallic spring flow to carry out sealing reliability, leaks easily.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of conduction loss little and reliable sealing water-cooled contact tube adapter sleeve.

Technical scheme: for achieving the above object, water-cooled contact tube adapter sleeve of the present utility model comprises the sealing ring that sleeve pipe, conical ring, nut and rubber are made; The outside of described internal surface of sleeve pipe is provided with the conical surface that can rabbet conical ring, and the conical surface of sleeve pipe is inner along being circumferentially with the cylinder groove.Be socketed with at the two ends of sleeve pipe conical ring along the nut that the conical surface inwardly compresses, make conical ring at sleeve pipe be connected between the copper pipe clamped.

In order to reach the purpose of airtight leakproof, internal surface of sleeve pipe and near the both sides of center line along the groove that circumferentially has two, interference is embedded with sealing ring in the groove, guarantees to be connected the seal between copper pipe and the sleeve pipe.

In order to reduce conduction loss, sleeve pipe and conical ring are respectively to adopt the T2 red copper to make sleeve pipe and conical ring.

In order to increase intensity and to reduce induction reactance, described nut is the nut that adopts brass to make.

Beneficial effect: adapter sleeve of the present utility model adopts conical ring, its conical surface that provides has increased the contact area of electric conductor, thereby reduced conduction loss, conical ring cooperates the structure with nut, can be within the specific limits the copper pipe of different-diameter be linked together, the airtight circle of rubber has guaranteed the seal of adapter sleeve by the interference fit with connector, and simple and reliable, and sleeve pipe and conical ring adopt the T2 red copper to make also to have reduced conduction loss.

Description of drawings

Fig. 1 is a schematic cross-section of the present utility model;

Fig. 2 is a structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

In conjunction with Fig. 1, shown in Figure 2, adapter sleeve critical piece of the present utility model has: sleeve pipe 1 that the T2 red copper is made and conical ring 2, and the nut 3 made of brass.Be provided with the conical surface 5 of inside contraction in the outside of sleeve pipe 1 inwall, can rabbet conical ring 2, the conical surface 5 is inner along being circumferentially with cylinder groove 6.Sleeve pipe 1 two ends are socketed with two nuts 3, and nut 3 inwardly compresses conical ring 2 along the conical surface 5, make conical ring 2 at sleeve pipe 1 be connected between the copper pipe 7 clamped.Edge, both sides at sleeve pipe 1 inwall and close center line circumferentially has two grooves, and interference is embedded with the sealing ring 4 that rubber is made in the groove, and when two copper pipes 7 were connected, sealing ring 4 had guaranteed the seal between sleeve pipe 1 and the copper pipe 7.

The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
