Abstract
The utility model relates to a double-pipe rotation joint for a rolling mill, which comprises a joint body (1), a water service pipe (5), a rotation shaft (2), a flange shaft sleeve (3), a stuffy cover (4) and a sealing assembly, wherein the flange on the flange shaft sleeve is arranged on the end surface of a rolling roller; the joint body is provided with two external connection pipe openings (6); the pointing direction of the external connection pipe openings is parallel with the axes of the flange shaft sleeve, and is opposite with the pointing direction of the installation surface of the flange shaft sleeve. The double-pipe rotation joint for a rolling mill is formed in the way that the cylinder part of the flange shaft sleeve is matched with the internal round hole at the end surface of the rolling roller, and the flange is fixedly connected with the end surface of the rolling roller. After an external pipe opening used for water inlet and water outlet, which is connected to the joint body, changed to face towards horizontal external direction from downward direction in the prior art, workers can directly observe the process when the double-pipe adapter is used for installing transition joints and metal flexible pipes. The utility model has the advantages of convenient installation, reliability and long service life.
Description
Technical field the utility model relates to the two-tube swivel joint of a kind of rolling mill, the external mouth of pipe especially wherein.
Background technology all will be installed a two-tube swivel joint so that cooling water is connected by its roll inner chamber with rotation through static pipeline at an end of roll in steel rolling equipment.This two-tube swivel joint has fittings body, and two extension tube attached are arranged on the fittings body, is with flanged (FLGD) axle sleeve on this hollow rotating shaft of hollow rotating shaft of installation on the fittings body axle sleeve and fittings body can be relatively rotated.One water service pipe is arranged again in this quill shaft, gapped between water service pipe and the quill shaft axis hole.Two couplings enter fittings body is constituted sealing respectively with the interior outer space of water service pipe after isolating passage, make to constitute the round passage of cooling water inside and outside water service pipe.After the axle sleeve upper flange is installed on the roll, connect two interfaces of the cooling-water duct of roll inner chamber inside and outside the water service pipe respectively.Two extension tube attached mouths of pipe of two-tube swivel joint of the prior art are all towards the below, be called " a kind of cool off the swivel joint that roll is used " as Chinese utility model patent ZL03255594.6 name, and patent ZL03255593.8 name to be called " a kind of cool off the double hose swivel joint that roll is used " disclosed.This is very inconvenient to the metal hose that transit joint or water flowing are installed, and the erector can not directly observe, and it is improper to cause sometimes installing, and causes leakage; In addition, be subjected to the restriction of installing space sometimes, metal hose is too crooked, thereby can influence its service life.
Summary of the invention is at above-mentioned deficiency, and the utility model provides a kind of two-tube swivel joint of reliable rolling mill of being convenient to observe, install.
The two-tube swivel joint of a kind of rolling mill of the present utility model, comprise fittings body, water service pipe, rotating shaft, flange form axle sleeve, stifle and black box, flange on the flange form axle sleeve is in order to be installed on the roll end face, fittings body has two external mouths of pipe, the installed surface directed in opposite of the sensing of the described external mouth of pipe and direction and flange form axle sleeve parallel with the axis of flange form axle sleeve.
The two-tube swivel joint of rolling mill of the present utility model, be to match by circular hole in the column part of flange form axle sleeve and the roll end face that merging fixes with the roll end face with flange is connected, its be connected on the fittings body the external mouth of pipe of using for Inlet and outlet water by the level that changes into down of prior art outwards after, when making installation transit joint of the present utility model, metal hose, the workman can directly observe, easy for installation, reliable, improve service life.
Appended drawings is the partial sectional view of rolling mill of the present utility model with two-tube swivel joint, among the figure: 1-fittings body, 2-rotating shaft, 3-flange form axle sleeve, 4-stifle, 5-water service pipe, the external mouth of pipe of 6-.
The specific embodiment as shown in drawings, rolling mill of the present utility model with two-tube swivel joint by fittings body 1, rotating shaft 2, flange form axle sleeve 3, stifle 4, water service pipe 5 and everywhere black box constitute.Rotating shaft is that quill shaft is fixedly installed in the fittings body, flange form axle sleeve and rotating shaft are made matched in clearance and can be relatively rotated, stifle is fixedly mounted on the flange form axle sleeve and points in the end of roll, stifle has and rotating shaft endoporus mesopore of the same size, external diameter less than the water service pipe of rotating shaft endoporus from connecting to stifle in the fittings body and exceeding the stifle end face.Each black box be installed on each need sealing part with guarantee not leak, not short circuit.Be separated with the cavity that only is connected with two extension tube attached respectively in the coupling body, cavity cooperates with the water service pipe inner chamber and forms airtight passage, and another cavity and rotating shaft cooperate the formation airtight passage with space between the water service pipe.Outside two extension tube attached on the coupling body were folded to perpendicular to axis earlier again, promptly this two external mouth of pipe 6 was that sensing water service pipe mouth is rightabout, is the opposite direction of pointing to the roll of being installed, or is called outside the sensing.During use, the flange form axle sleeve is connected with bolting with the roll end face, and be with commentaries on classics synchronously by roll, two external mouths of pipe of level of fittings body respectively with advance, the backwater metal hose joins, formation is from water inlet, through water inlet pipe, roll inner chamber, rotating shaft inner chamber,, reach the purpose of cooling roll after the cavity delivery port of fittings body is got back to the loop of water tank.
