The technical scheme includes that serrated bosses are sequentially arranged at the tail of a core, two or three rectangular grooves are sequentially formed in the tail of the core and are close to the tail end of the core as compared with the serrated bosses, the width of each rectangular groove ranges from 1mm to 1.5mm, and the depth of each rectangular groove ranges from 0.3mm to 1mm. The labyrinth rubber tube core has the advantages that the rubber tube core is good in sealing performance, and leakage at a joint of a tube and a rubber tube connector can be prevented; the labyrinth rubber tube core is applied to high-pressure rubber tube assemblies of hydraulic systems.
Description
Technical field
Mazy type sebific duct fuse, belongs to the high-pressure rubber pipe assembly base components technical field of hydraulic system.
Background technique
High-pressure rubber pipe assembly is base components indispensable in hydraulic system, is mainly used in the fields such as metallurgical machinery, engineering machinery, coal mine machinery and automobile.The quality of hose assembly directly affects the performance of system and main frame, and serious will cause equipment outage, and the serious accidents such as personal injury even can occur, so, the quality problems of high-pressure rubber pipe assembly are caused to Professional visitors's great attention.
High-pressure rubber pipe assembly is generally made up of rubber hose coupling and body.Rubber hose coupling comprises fuse, sleeve two-part.Sleeve produces expendable plastic deformation after special device is withheld, and fuse, sleeve and body are combined (as shown in Figure 1) effectively.
The each parts of hose assembly all play seal action; Rubber tube body itself is made up of inner glue layer, enhancement layer and outer glue-line three parts, and inner glue layer has ensured the sealing of high-pressure rubber pipe; The groove width of sebific duct fuse and sleeve and the degree of depth have also determined the sealing of high-pressure rubber pipe; The sealing of high-pressure rubber pipe assembly is by means of overcoat and fuse, inner glue layer to be out of shape by the inner glue layer of sebific duct.
The inefficacy main manifestations of hose assembly is that seepage, pull-off or explosion appear in body and rubber hose coupling joint.We study discovery, and its main cause is that the inner glue layer deformable seal face that zigzag fashion boss forms after withholding is continuous slope, relatively easily occur causing because of seal failure the leakage of hose assembly or fuse from body by defects such as pull-offs.Because medium leaks into body end along the zigzag fashion outer wall of fuse, and enter between the enhancement layer of body and outer glue-line and progressively form fluid passage, in the time that there are impact or fluctuation pressure certain moment, because reaching extreme value, outer glue-line pressure-bearing will cause seepage or the direct explosion of body (as shown in Figure 2).Thereby also increase obvious economic loss fast reducing hose assembly working life.
Model utility content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of good airproof performance, body and rubber hose coupling joint and is not prone to the sebific duct fuse of seepage.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts: mazy type sebific duct fuse, afterbody at fuse is provided with zigzag fashion boss and rectangle groove successively, and described rectangle groove is compared zigzag fashion boss near fuse tail end, the quantity of described rectangle groove is two or three, the groove width of described rectangle groove is 1-1.5mm, and groove depth is 0.3-1mm.
The quantity of described rectangle groove is three, and the groove width of described rectangle groove is 1mm, and groove depth is 0.5mm.
Compared to the prior art the utility model has following beneficial effect.
One, sealing is reliable, because the afterbody at traditional fuse increases by two or three rectangle grooves, therefore after special device has been withheld, the inner glue layer of body can be filled in two or three rectangle grooves, form independently two Dao Huo tri-road labyrinth sealings, well play the effect of sealing and damping, strengthen greatly the ability that stops medium seepage, and the sealing effect that original zigzag fashion boss also keeps traditional fuse to form due to inner glue layer after withholding further plays the de-effect of auxiliary seal and resistance to plucking.
Two, cost is low, versatility is high, because the afterbody at traditional fuse just increases by two or three rectangle grooves, original zigzag fashion boss structure retains, original supporting sleeve also can be general and need not be again customized, and the processing technology of rectangle groove is identical with original zigzag fashion boss processing technology: be turning process, make this device still can general original supporting sleeve when fabricating cost is low, good economy performance.
Three, reliable operation, long service life, because this device is not prone to leakage loss, working stability, has therefore extended working life of hose assembly, has avoided the economic loss causing because losing efficacy.
