Abstract
The invention relates to an M-type rotary joint which comprises a double-end joint, a joint body, an inner water pipe and a hollow shaft component. A plurality of O-type ring grooves are arranged on the double-end joint and the joint body, O-type sealing rings are arranged in the O-type ring grooves, an internal circlip is further arranged on the joint body, the hollow shaft component is fixedly arranged in the joint body, the joint body is fixedly arranged at the position of an inner hole end face of the double-end joint, and the inner water pipe penetrates through the inner hole of the hollow shaft component to be screwed with the double-end joint. Burden of the double-end joint is relieved, and the M-type rotary joint is attractive in appearance, less in external occupied space, simple in structure, economical, practical, convenient to maintain and replace and higher in sealing performance and can achieve separate material supply without affecting normal use of rollers of a continuous casting machine.
Description
Technical field
The present invention provides the cooling unit of the roller on a kind of casting machine in order to overcome the above problems, and relates in particular to a kind of M type swivel joint.
Background technique
The temperature of control Continuous Casting Machine Rollers is the key that prolongs normal running and reduce maintenance cost.Controlling energetically liquid stream and temperature produces defective and guarantees that product stability is extremely important for avoiding in the casting process.Swivel joint allows cooling water to flow into and flows out Continuous Casting Machine Rollers, so that the temperature of control roll and bearing prevents bearing failure.Existing swivel joint volume is large, Heavy Weight, and sealing is relatively poor, and leakage accident easily occurs, and working life is shorter.
Summary of the invention
The present invention is in order to overcome the above problems the M type swivel joint that a kind of simple in structure, easy to use, good airproof performance, long service life are provided.
Technological scheme of the present invention is: comprise double end joint, adapter body, inner conduit, hollow shaft assembly, double end joint and adapter body are provided with some O type ring recess and the O RunddichtringO are set in it, also be provided with circlip for hole on the adapter body, described hollow shaft assembly is fixedly installed in the adapter body, adapter body is fixedly installed on the endoporus end of double end joint, inner conduit pass the hollow shaft assembly endoporus and with the double end joint rotating connection.
Described hollow shaft assembly comprises hollow shaft, graphite annulus, skeleton-type oil seal, packing ring one and packing ring two, described graphite annulus, skeleton-type oil seal, packing ring one and packing ring two are arranged on the cylindrical of hollow shaft, and described graphite annulus one end is provided with back-up ring and circlip for hole.
The present invention is because its main body is imbedded Continuous Casting Machine Rollers, and its weight is mainly born by Continuous Casting Machine Rollers, has alleviated double end joint burden.And the swivel joint major part imbeds roller inside, and as seen the outside only has the double end joint, and beautiful shape takies space outerpace few.The present invention is simple in structure, can supply separately, does not affect the normal use of Continuous Casting Machine Rollers, and is economical and practical, and maintenance and replacing are all very convenient.Skeleton-type oil seal can Leakage prevention, some O RunddichtringOs on the adapter body respectively with endoporus and the end face drive fit of Continuous Casting Machine Rollers, further prevented leakage, increased sealability, the effect of graphite annulus is similar to oilless bearing, and the existing rotary action of oilless bearing does not need to lubricate all the life, increased again the characteristics of sealing because of the self-characteristic of graphite annulus, economical and practical.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is the double end joint among the figure, the 2nd, and inner conduit, the 3rd, hollow shaft, the 4th, graphite annulus, the 5th, adapter body, the 6th, skeleton-type oil seal, the 7th, packing ring one, 8th, packing ring two, 9th, O RunddichtringO one, the 10th, O RunddichtringO two, 11st, back-up ring, the 12nd, circlip for hole, the 13rd, O RunddichtringO three.
Embodiment
A kind of M type swivel joint, comprise double end joint 1, adapter body 5, inner conduit 2, hollow shaft assembly, double end joint 1 is provided with one group of O type ring recess and the O RunddichtringO is set in it, adapter body 5 is provided with three groups of O type ring recess and the O RunddichtringO is set in it, also be provided with circlip for hole 12 on the adapter body 5, described hollow shaft assembly is fixedly installed in the adapter body 5, adapter body 5 is fixedly installed on the endoporus end of double end joint 1, and inner conduit 2 passes the endoporus of hollow shaft assembly and screws with double end joint 1.Described hollow shaft assembly comprises hollow shaft 3, graphite annulus 4, skeleton-type oil seal 6, packing ring 1 and packing ring 28, described graphite annulus 4, skeleton-type oil seal 6, packing ring 1 and packing ring 28 are arranged on the cylindrical of hollow shaft 3, and described graphite annulus 4 one ends are provided with back-up ring 11 and circlip for hole 12.
During assembling, at first graphite annulus 4, packing ring (two) 8, skeleton-type oil seal 6, packing ring () 7 are contained on the cylindrical of hollow shaft 3 successively, to hollow shaft 3 steps, then in the adapter body 5 of the hollow shaft assembly being packed into, interior hole end surface to adapter body 5, then put into spacer ring 11 and block graphite annulus 4, in the jump-ring slot of the adapter body 5 of then circlip for hole 12 being packed into, the fixation hollow shaft assembly prevents that it from endwisely slipping.Then O RunddichtringO (three) 13 is put into the O type ring recess of double end joint 1, and then adapter body 5 assemblies are packed in the hole of double end joint 1, end to double end joint 1 endoporus, then fix double end joint 1 and adapter body 5 with fluting cone end Cock screw and hexagon thin nut, then inner conduit 2 is passed the endoporus of hollow shaft 3, screw, screw with double end joint 1, then O RunddichtringO () 9, O RunddichtringO (two) 10 are respectively charged in the O type ring recess of adapter body 5, so far whole M type swivel joint assembling finishes again.
