Abstract
The utility model relates to a spherical rotary join used in evaporated cooling systems of heating stoves and other parts with the need of rotary motions. The utility model is composed of a casing, a spring, a major and an auxiliary sealing rings, a sphere, a flange and a pressing flange for sealing the casing, wherein, the pressing flange (6) and the flange (11) of the casing are connected together through a correcting screw bolt (7), and a gap (10) exists between the pressing flange (6) and the flange (11) of the casing. The major and the auxiliary sealing rings are made of sealing material by adding copper powder from 20 to 60% into polyfluortetraethylene. The utility model can achieve on-line correction conveniently, having the advantages of leakage prevention, long service life and favorable wear-proof and aging-proof performance.
Description
The utility model is a kind of spheroid swivel, is used for the spheroid conversion adapter of oven, evaporated cooling system and other need rotation motion parts.
Existing spheroid swivel is secondary seal ring, the flange by the special graphite of the stainless steel spheroid of metal, primary seal circle that teflon is mixed soft particular fillers, hard, and stainless steel spring, metal shell and outer housing cover are formed.Because between shell and the outer housing cover is close-coupled, no gap, non-adjustable, makes seal ring tightly be close to spheroid by the unidirectional spring force of spring and prevent to leak.Because above-mentioned spheroid swivel folk prescription can't onlinely be aligned to stressed, go wrong after use a period of time (as sewing) have to pull down the back off-line and repair, as changes seal ring etc.
The purpose of this utility model is to provide a kind of spheroid swivel that adopts the bidirectional stress sealing, when using the back as problems such as appearance leakages, can onlinely align by this joint, make seal ring prevent to sew near spheroid, simultaneously seal ring adopts teflon to add the sealing material of copper powder, thereby has guaranteed sealability and increase the service life.
The purpose of this utility model is achieved in that
With shell seal, the shell flange connects with bolt with differential this spheroid swivel with a differential, leaves a gap between shell flange and the differential.When seal ring uses the back wearing and tearing to occur and when causing sewing, tighten bolt on flange and the differential and the gap is eliminated and make seal ring be close to spheroid to seal better.In addition, the material of making seal ring is that teflon adds 20～60% copper powder (weight percentage).
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a spheroid swivel structural representation of the present utility model.
Spheroid swivel of the present utility model is by shell 1, spring 2, and secondary seal ring 3, primary seal circle 4, spheroid 5, flange 9, centering bolt 7 and differential 6 are formed.Differential 6 is linked together by the shell flange 11 on centering bolt 7 and the shell 1, between shell flange 11 and differential 6, leave gap 10, the gap can be 5～15mm, shell flange 11 and differential 6 are along being evenly distributed with the screw that is used for laying centering bolt 7 on the circumference, the quantity of centering bolt 7 is 6～40, according to the differential diameter, differential pitch of bolts and differential end face bear the size of pressure and determine.
The spring 2 of spheroid swivel of the present utility model is contained in the shell 1, tightly pushes down secondary seal ring 3 and makes it near living metal ball body 5, and primary seal circle 4 is near the boss on the differential 6 12.Making the gap 10 between differential 6 and the shell flange is 5～15mm, the screwing force of the centering bolt 7 on the differential 6 guarantees that major and minor seal ring is close to spheroid 5, bear the certain pressure, uniform temperature of the medium in the pipeline and no-leak, guarantee that simultaneously spheroid rotates freely, finishes and rotate and no-leak purpose.Joint two end flange 9 are connected with the pipeline of fed sheet of a media.After using a period of time, seal ring is worn and causes when sewing, and the nut 8 on the centering bolt 7 of connection differential 6 and shell flange 11 can be tightened equably, and gap 10 is reduced.The differential boss 12 of pushing down the spring 2 of secondary seal ring 3 and withstanding primary seal circle 4 produces bigger two-sided pressure, thereby makes two seal rings further be close to spheroid 5, the problem such as sew that having stoped that wearing and tearing cause.
In addition, the sealing material that major and minor seal ring selects for use teflon to add 20～60% copper powders (weight %) make have ageing-resistant, the life-span is long, good wear resistance, lower friction ractor, high compression strength, thereby assurance seal request.
The utility model reaches online levelling owing to adopt spring force and the bidirectional stress structure of Bolt Tightening Force has overcome single load bearing etc. and can not align the existing problem of existing spheroid swivel that must pull down replacing, prevents to sew to increase the service life.
