Description
Technical field
This utility model relates to a kind of tri-color tube that can carry out safely liquid feeding.
Background technology
At present, tri-color tube on the market is when to system liquid feeding, and in tri-color tube, the cold-producing medium of residual can be directly discharged in air, the most both cold-producing medium had been wasted, pollute the environment again, therefore be badly in need of developing a kind of tri-color tube that can prevent residual refrigerant from leaking, to meet the market demand.
Utility model content
For the shortcoming of prior art, this utility model provides a kind of tri-color tube with safe liquid adding functions.
For achieving the above object, this utility model adopts the technical scheme that tri-color tube, including body, connect on described body and have joint, described joint is sealedly and fixedly connected with described body, described joint includes straight core, elastic sealing device, inner sleeve, overcoat, described overcoat be set in described in put, described inner sleeve is flexibly connected with described overcoat, described inner sleeve is set on described straight core, inner sleeve described in one end of described straight core is sealedly and fixedly connected, the other end of described straight core is sealedly and fixedly connected with described body, described elastic sealing device is positioned at described straight core inner, described elastic sealing device is flexibly connected with described straight core.
In this utility model one embodiment, described elastic sealing device includes spring, mobile core, and one end of described spring is fixing with described inner sleeve to be connected, and the other end of described spring is fixedly connected with described mobile core.
In this utility model one embodiment, between described inner sleeve and described mobile core, be provided with Sealing shield ring, described Sealing shield ring be fixedly installed on described in put.
In this utility model one embodiment, described straight core being additionally provided with elastic impeller, described elastic impeller is sealedly and fixedly connected with described body.
In this utility model one embodiment, described overcoat inner surface is additionally provided with jump ring back-up ring.The setting of jump ring back-up ring makes can rotate freely between overcoat and inner sleeve.
In this utility model one embodiment, being arranged with pipe box on the body of described joint, described pipe box is convex-concave shape.Convex-concave shape pipe box makes to realize between elastic impeller and body well sealing.
In this utility model one embodiment, described body is fixedly connected with inlet away from the other end of described joint, and described feeding device is connected with described body.
This utility model has the advantages that
Joint realizes being tightly connected with the body of tri-color tube by the straight core of impeller that band is elastic, simultaneously by connecting the inner sleeve with Sealing shield ring on straight core, the one end making mobile core abuts against with Sealing shield ring, when tri-color tube is connected with liquid feeding equipment, mobile core is pressed into, spring is compressed, so that tri-color tube is connected with system, the liquid in tri-color tube enters and treats liquid feeding equipment；When tri-color tube disengages with liquid feeding equipment, mobile core meeting automatic rebounding, it is achieved automatic-sealed, thus ensure that the cold-producing medium of tri-color tube internal residual will not leak；The jump ring back-up ring putting outward setting makes to relatively rotate between overcoat and inner sleeve, straight core, it is simple to tri-color tube with treat that liquid feeding equipment is attached.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing 1, the utility model will be further described.
Tri-color tube involved by this utility model, including body 11, connect on described body 11 and have joint, described joint is sealedly and fixedly connected with described body 11. and described joint includes straight core 1, elastic sealing device, inner sleeve 6, overcoat 9, described overcoat 9 is set in described inner sleeve 6, and described inner sleeve 6 is relatively rotated by the jump ring back-up ring 4 being arranged on overcoat 9 inner surface with described overcoat 9.Described inner sleeve 6 is set on described straight core 1, and inner sleeve 6 thread seal described in one end of described straight core 1 connects, and the other end of described straight core 1 is sealedly and fixedly connected with described body 11.
It is internal that described elastic sealing device is positioned at described straight core 1, and described elastic sealing device includes spring 2, mobile core 3, and one end of described spring 2 is fixing with described inner sleeve 6 to be connected, and the other end of described spring 2 is fixedly connected with described mobile core 3.Being provided with Sealing shield ring 7 between described inner sleeve 6 and described mobile core 3, described Sealing shield ring 7 is fixedly installed in the groove in described inner sleeve 6.It is additionally provided with O 5 so that between each parts, obtain required fitness between described inner sleeve 6 and described straight core 1.
Being additionally provided with elastic impeller 12 on described straight core 1, described elastic impeller 12 is sealedly and fixedly connected with described body 11.Being arranged with pipe box 10 on the body 11 of described joint, described pipe box 10 is in convex-concave shape, and convex-concave shape pipe box 10 makes to realize between elastic impeller 12 and body 11 well sealing.
When using this utility model to carry out frame liquid, one end of tri-color tube body is connected with going out liquid equipment, the other end is fixedly connected with inlet, described feeding device is connected with described body, with treat that liquid feeding equipment is connected, under the effect treating liquid feeding equipment screwing in overcoat 9, mobile core 3 is toward there being a side shifting of spring, thus compression spring, tri-color tube is connected with system, and the liquid in tri-color tube enters and treats liquid feeding equipment；After completing liquid feeding, tri-color tube disengages with liquid feeding equipment, and now, mobile core 3 meeting automatic rebounding, in situ, seals with Sealing shield ring 7 and connects, thus realize automatic-sealed, it is ensured that the cold-producing medium of tri-color tube body 11 internal residual does not leaks.
Above-mentioned specific embodiment is used only to illustrate this utility model; rather than be that this utility model is limited; in objective of the present utility model and scope of the claims; the any replacement not paying creative work making this utility model and change, fall within the protection domain of this utility model patent.
