Abstract
The utility model relates to a non-leakage rotary joint, which belongs to an accessory of a heating apparatus, and the non-leakage rotary joint is used for heating apparatuses, such as packaging products, chemical industries, papermaking, rubber, etc. The utility model is characterized in that the non-leakage rotary joint is composed of a casing which is made of steel and is provided with an oil chamber and a rotating chamber, and an oil supplying joint, a driving shaft, double rows of centripetal spherical bearings, bearing partition pads, a sealing ring, a press cover, a fastening bolt and a fixed claw which are arranged on or in the casing. The utility model has the advantages of simple structure, no any leakage, no pollution, good sealing performance, safety, low cost, energy saving, etc.
Description
A kind of nothing is leaked swivel joint, belongs to the accessory technical field of heating plant, is mainly used in to used heating plants of industry such as packaging article, chemical industry, papermaking, rubber to match.
In the prior art, for the matching used swivel joint of above-mentioned every profession and trade heating plant, generally all adopt cast iron housing, graphite annulus plane contact friction also utilizes the elasticity of spring to realize sealing and rotate.Thereby its poor sealing, vapour, leakage of oil are leaked in normal appearance, dangerous, problem such as waste energy, for steam-heating apparatus, because serviceability temperature is generally only between 170～180 ℃, just leak the problem of vapour, still can gather together and use, but for the oil heating, because serviceability temperature is generally all up to more than 260～280 ℃, spring is so soaking under the high temperature for a long time, annealing can take place spring force is descended, add that the impurity that conduction oil is produced constantly accumulates in continuous circuit process, must cause bad sealing and produce leakage of oil.Leakage of oil one is the smog that can produce the people that chokes under the high temperature, and befouling environment impairs health; The 2nd, fire hazardous is absolutely unsafe; The 3rd, waste oil increases operating cost.Not only intensity is low for cast iron housing in addition, break often being connected with miscellaneous part, and structure and manufacturing process is all complicated cost height, 540～780 yuan of the about RMB of the every cover of existing swivel joint.
The purpose of this utility model is to provide a kind of design science, and is rational in infrastructure, can thoroughly solve existing all problems in the prior art, do not leak, and pollution-free, cost is low, and nothing safe in utilization is leaked swivel joint.
According to the structural feature of heat transfer oil heater, at existing questions in the prior art, basic design of the present utility model is: put into the melting pot on the basis of existing swivel joint.Promptly at first cancel parts such as original graphite annulus, spring and spring seat, adopt heatproof the cover of two more than 500 ℃ biserial entad spherical bearing replace graphite annulus, secondly the procapsid material is changed into the 45# steel by cast iron and carry out heat treatment earlier before processing, make its typing, so not only make housing increase intensity, but also make it at high temperature indeformable, change former rotation and sealing means once more, the way that adopts turning cell and grease chamber to separate, make impurity that conduction oil produces etc. can not enter turning cell, thereby realize purpose of design.
Nothing described in the utility model is leaked swivel joint, joint housing 1 that is connected with the return line of heating plant by its rear portion and dress thereon and/or in it with add the fuel feeding connecting head 2 that the fuel feeding metallic hose is connected, the joint transmission shaft 3 that one end is threaded with heating plant, gland 7, clamping bolt 8 and the joint fixed claw 9 that joint is fixed on the heating plant constitute, it is characterized in that its above-mentioned joint housing of this swivel joint 1 for steel and its inner chamber be provided with not connected grease chamber 10 and turning cell 11, the joint rotatingshaft between above-mentioned fuel-intake connection 2 and gland 73 is outer simultaneously installs two and overlaps entad spherical bearings 4 of biserials, bearing dottle pin 5 and seal ring 6.
Above-mentioned joint transmission shaft 3, biserial entad spherical bearing 4, bearing dottle pin 5 and seal ring 6 fit together, and joint transmission shaft 3 closely cooperates with bearing 4, by above-mentioned gland 7 and clamping bolt 8 they are sealed in the above-mentioned turning cell 11 again.
The utility model has the advantages that design science is reasonable, structure is simpler, and the material saving seals tightlyer, guarantees that conduction oil neither can leak, and also can not enter turning cell, and is pollution-free, safe and reliable, becomes instinct to reduce by 1/3～1/2.
Accompanying drawing is the vertical vertical profile overall structure of a first half schematic representation under the user mode of one of the utility model most preferred embodiment assembling back.
In conjunction with the accompanying drawings and most preferred embodiment, further describe structure characteristic of the present utility model as follows: the return line of and heating plant latter half of at it is provided with grease chamber 10 and the turning cell 11 that is not connected mutually by joint housing 1 inner chamber that processes with the 45# steel that screw thread is connected, on this housing 1 with in its shell, be equipped with successively from back to front and add the fuel feeding metallic hose and be connected and be welded on fuel feeding connecting head 2 on the housing 1, one end is connected with heating plant by screw thread and is enclosed within joint transmission shaft 3 on the equipment return tube, the turning cell 11 of its cylindrical and above-mentioned housing 1 closely cooperates conduction oil can not be entered, and interior garden and transmission shaft 3 closely cooperate and its front end has two of back-up ring to overlap entad spherical bearing 4 of biserials, between two cover bearings, be used for two cover bearings being separated and making them leave the bearing dottle pin 5 and the seal ring 6 of certain adjusting play, elder generation is with above-mentioned joint transmission shaft 3 during installation, two cover biserials are spherical bearing 4 entad, with gland 7 and clamping bolt 8 their sealing is installed in the turning cell 11 of housing 1 again after bearing dottle pin 5 and seal ring 6 fit together, by the joint fixed claw 9 that is located at the housing front portion this swivel joint is fixed on the heating plant at last.
Change as present embodiment:
The external form of housing, size can change along with the size of heat.
