Abstract
The utility model discloses a kind of micro flow pipe joint structure, including cutting ferrule, inner tube, said inner tube includes input end, outlet end, and said inner tube is socketed cutting ferrule, the accurate nozzle outside the outlet end connection in input end side；There is connection screw thread, the cutting ferrule to extend a tapered cooperation connector along import extreme direction for the cutting ferrule outer surface, and the cooperation connector end is provided with matching hole.The utility model structure design is simply accurate, coordinates external valve module and accurate nozzle, it can be achieved that microdose flow stablizes transmission, service life is long.
Description
Technical field
The utility model belongs to fluid transmission field more particularly to a kind of micro flow pipe joint structure.
Background technology
It needs to weld in photovoltaic, field of lithium, and welds precision height, scaling powder is a kind of utilization chemical method cleaning
The substance carried out in order to soldering, brazing or positioning welding by weldering metal surface.Common scaling powder is that colophony powder is dissolved in wine
It is refined into, when this scaling powder is transmitted, corresponding part of appliance is welded metal surface, it is desirable that precision is higher, and range limits
It is relatively stringent, so the stability and controllability of transmission process are very important one of process conditions.
Most of scaling powder transmission use micro flow pipe, but the position that some connecting portions and traffic characteristic change at present
Unstable, the easy leakage of fluid is easily caused, flow is difficult to control after connector is connected to valve, and the utility model is directed to micro flow
The unique joint structure of special construction design of pipe, is transmitted with adapting to stablizing for microdose fluid.
Utility model content
Purpose of utility model：The utility model proposes a kind of micro flow pipe joint structures, and the structure design is simple, but can
So that low dose of flux solvent stablizes transmission and controllable, to overcome problems of the prior art.
Utility model content：A kind of micro flow pipe joint structure, including cutting ferrule, inner tube, said inner tube include input end,
Outlet end, said inner tube are socketed cutting ferrule, the accurate nozzle outside the outlet end connection in input end side；The cutting ferrule appearance
There is connection screw thread, the cutting ferrule to extend a tapered cooperation connector, the cooperation connector end along import extreme direction in face
End is provided with matching hole.
Preferably, the aperture of the matching hole is less than inner tube diameter.Matching hole aperture is compared with inner tube diameter size
It is particular about and is, form specific hydrodynamics effect, reduce resistance（Reaming）And keep flowing more stable.
Preferably, distribution distance of the connection screw thread in cutting ferrule outer surface accounts for more than half of cutting ferrule length.Connection
The distribution distance of screw thread is wanted to make connector itself that can form fabulous cooperation with external valve arrangement.
Preferably, the outer diameter of the cutting ferrule is not less than 2 times of interior pipe outside diameter, the length for being shorter in length than inner tube of the cutting ferrule
Degree.Cutting ferrule outer diameter, length it is reasonable setting can it is easy to process, save material, rationally with merge keep it is mechanically stable.
Further, the outer diameter of the cutting ferrule is 3-6mm.The suitable outer diameter of cutting ferrule supports the effect of micro flow stable structure.
Preferably, the cutting ferrule is socketed on inner tube in a manner of expanded joint or interference fit.Expanded joint or interference fit are secured
Reliably.
Compared to the prior art, the beneficial effects of the utility model are：The utility model is simple in structure, easy to operate,
Cooperation is reliable, and transmission is made to stablize.Cutting ferrule, which is socketed on inner tube, makes miniature inner tube not participate in structure function directly, keeps transfer conduit
It is mechanically stable；Outlet end and input end is discrete and input end side is socketed cutting ferrule, it is rationally distributed, it is flexible for installation；Coordinate connector
Reaming pyramidal structure keep this connecting portion running resistance small, transmission it is reliable and stable.The utility model structure design is simply smart
It is close, coordinate external valve module and accurate nozzle, it can be achieved that microdose flow stablizes transmission, service life is long.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
In figure：1- cutting ferrules, 11- connection screw threads, 2- inner tubes, 21- input ends, the outlet ends 22-, 3- coordinate connector, 31- cooperations
Hole.
Specific implementation mode
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, letter will be made to embodiment below
Single introduction.
Such as Fig. 1, a kind of micro flow pipe joint structure, for the valve module of micro flow Transmission system, including cutting ferrule
1, inner tube 2, said inner tube 2 include input end 21, outlet end 22, and said inner tube 2 is matched in 21 side of input end with expanded joint or interference
The mode of conjunction is socketed with cutting ferrule 1, and the outlet end 22 connects external accurate nozzle, and the outer diameter of the cutting ferrule 1 is not less than inner tube 2
The outer diameter of 2 times of outer diameter, the cutting ferrule 1 is 3-6mm, the length for being shorter in length than inner tube 2 of the cutting ferrule 1；
There is 1 outer surface of the cutting ferrule connection screw thread 11, distribution distance of the connection screw thread 11 in 1 outer surface of cutting ferrule to account for
More than half of 1 length of cutting ferrule, preferably 1 overall length of cutting ferrule；The cutting ferrule 1 is tapered along 21 direction of input end extension one
Cooperation connector 3,3 end of cooperation connector is provided with matching hole 31, and the aperture of the matching hole 31 is less than 2 internal diameter of inner tube, from
And expanding structure is formed to 2 direction of inner tube along matching hole 2.
Above example is only to illustrate the optimal technical scheme of the utility model, it is noted that for the art
Those of ordinary skill for, without departing from the principle of this utility model, several improvement made or equivalent replacement,
It is accordingly to be regarded as the scope of protection of the utility model, should be covered in the right of the utility model.
