Specific implementation mode
Core of the invention is to provide a kind of gas leak detection pipette tips, to reduce check frequency.The present invention another core be
A kind of gas leak detection equipment with above-mentioned gas leak detection pipette tips is provided.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1-Figure 3, the invention discloses a kind of gas leak detection pipette tips, including butt joint 1, main air intake duct 2 and auxiliary
Air intake duct 3.Wherein, for 1 one end of butt joint for being connected to gas leak detection equipment, the other end is connected to main 2 He of air intake duct for sealing
Auxiliary air intake duct 3, the butt joint 1 are used to summarize the air-flow of main air intake duct 2 and auxiliary air intake duct 3, and the air-flow of the two is summarized rear and gas
Body leak test plant is connected to, and detection gas are summarized and is sent to gas detection leak test plant and analyzes, is i.e. remittance is played in the butt joint 1
Summation signaling transfer point.In practice, which requires sealing air tight, avoids collaborating to ensure that pressure of inspiration(Pi) is enough.This
Outside, the axis of main air intake duct 2 and the axis of auxiliary air intake duct 3 have angle, to realize that the gas leak detection pipette tips are sampled in detection
When carry out analysis detection for multi-direction multi-angle adsorbed gas, increase detection covering surface.The gas leak detection pipette tips have broken list
Tubular type detects the barrier of pipette tips, and forming multi-faceted packaging type to pipeline detects, and improves the accuracy of detection.
In practice, the number for main air intake duct 2 and auxiliary air intake duct 3 and arrangement can according to different needs into
Row setting, the core of the application are the angle of increase detection, reduce check frequency, therefore, scheme on this basis all exists
In protection domain.
With reference to the olfactory organ of star nose mole in the application, the multi-faceted gas detection of solid space is realized, specifically, will
The axis of main air intake duct 2 is set as overlapping with the axis of butt joint 1, i.e., the main air intake duct 2 is centrally located, and by auxiliary air-breathing
Pipe 3 is set as multiple, circumferentially around main air intake duct 2.Specifically, it is main inspection that main air intake duct 2, which is linear air suction structure,
Gas access is surveyed, leading role is played, entire pipette tips center is occupy, mainly for detection of front leakage point.Specific embodiment
In, since the position of the main air intake duct 2 haves no need to change, set main air intake duct 2 to the larger hard tube structure of hardness,
I.e. in artificial force can not deformation, can be specifically hard plastic tube or metal tube.
In one embodiment, can set auxiliary air intake duct 3 to 6 can deform upon the soft of change direction in stress
It manages, and these hoses is uniformly looped around to the circumferential direction of main air intake duct 2, form hexagon.These auxiliary air intake ducts 3 are due to can shape
Become, therefore, mainly for detection of the leakage point gas of absorption pipeline side and the back side, forms three-dimensional encirclement.The application utilizes
Hose construction is convenient for covering the package for detecting body, increases the range of sampling, improves the accuracy of detection.Preferably, should
Its shape invariance in no external force of auxiliary air intake duct 3, need to change towards when, operator only needs force to change auxiliary air intake duct
3 shape.
Since main air intake duct 2 is located at the centre of butt joint 1, directly docked with main pipeline, and auxiliary air intake duct 3 and butt joint 1
Main pipeline have angle, increase the resistance of gas, therefore, the bore of main air intake duct 2 be set smaller than to the mouth of auxiliary air intake duct 3
Diameter sucks auxiliary 3 gas concentration of air intake duct of Dilution air and the problem of influence auxiliary 3 working effect of air intake duct to alleviate main air intake duct 2.
In preferred embodiment, auxiliary air intake duct 3 will be longer than main air intake duct 2, specifically, difference will be in 10mm or more, to keep away
Exempting from the interference of main air intake duct 2 causes auxiliary air intake duct 3 not touch detection body, while should not be long, and difference does not exceed 100mm, mistake
Length can cause to suck Dilution air by main air intake duct 2 because gas transmission path is long, and detection sensitivity is caused to decline.
In another embodiment, auxiliary 3 length of air intake duct of the six roots of sensation can also be set to difference, the distribution of forming layer grade is preferably divided into
Two each levels, every three levels, can increase covering volume, specifically, the length of auxiliary air intake duct 3 from main air intake duct 2 to
Direction far from main air intake duct 3 increases, i.e., increases from inside to outside, to ensure that auxiliary air intake duct 3 can touch detection body.
In addition, disclosed herein as well is a kind of gas leak detection equipment, including gas leak detection pipette tips, wherein the gas leak detection
Pipette tips are the gas leak detection pipette tips as disclosed in above-described embodiment, therefore, the gas leak detection equipment with the gas leak detection pipette tips
Also there are all features disclosed in above-described embodiment, this is no longer going to repeat them.
The gas leak detection pipette tips are adapted to all gas leak test plant, and feature becomes apparent during high speed is hunted leak.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest range caused.
