Abstract
The invention belongs to a multi-functional gas sampling device. The multi-functional gas sampling device comprises a bag body (1), wherein the upper end of the bag body (1) is pressed to form a sealed tail fin (3) and two sides of the bag body (1) are pressed to form sealing edges (2). The multi-functional gas sampling device is characterized in that a guide hole B (8) is formed in one side of a valve seat upper cover (17) of a valve seat (4), an annular sliding groove (9) is formed in the external circle of the upper end of the valve seat (4), an annular boss (10) is arranged on the inner circle of the lower end of a valve cover (7), a guide hole A (5) is formed in one side of a valve cover pressure plate (6), a bag body opening (15) at the lower end of the bag body (1) winds a hollow reel (13), and two layers of folded perforated films (11) are arranged inside the bag body (1). The multi-functional gas sampling device has a wide application range, is particularly suitable for collecting of gas samples from various solid materials, can be used repeatedly, can be vacuumized, is convenient to operate and has a simple structure.
Description
Technical field
The invention belongs to collection gas apparatus, particularly a kind of multifunctional gas sampling apparatus.
Background technology
The harvester of gas sample all will use in a lot of fields, in medical industry, by expiration gas sample assay is detected to the mushroom in stomach; In environmental protection, will carry out gas sample acquisition and analysis to atmosphere, earth, each Plants and many textile materials also need to get its Volatile Gas sample to be analyzed, and purposes is very extensive.
At present modal is the gas production sample bag of applying in medical industry, and its function singleness particularly cannot be carried out the volatilization gas sampling of solid material.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of collection that is not only applicable to gas is provided, but also be applicable to the Volatile Gas sample of various solid materials to gather also reusable, easy to operate, simple in structure multifunctional gas sampling apparatus.
The technical scheme that technical solution problem of the present invention adopts is: a kind of multifunctional gas sampling apparatus, comprise that bag upper end is pressed into sealing empennage, both sides are pressed into edge sealing, a valve seat is fixed at center at sealing empennage, it is characterized in that being provided with a guide hole B in a side of valve seat upper cover, in valve seat upper end, cylindrical is established annular chute; In valve seat upper end, valve gap is housed, the inner circle of valve gap lower end is provided with annular boss, and boss is meshed with chute, is provided with valve gap pressing plate in valve gap, and a side of valve gap pressing plate is provided with guide hole A, and valve gap pressing plate and valve seat upper cover closely cooperate.The opening film of bag lower end twists on hollow spool, uses internal clip clamping films, and the end of internal clip is provided with clamping slot, is clipped in clamping slot with the termination of external clip in internal clip outside, and bag opening is further fixedly clamped.Two layers of folding line perforated film are set in bag.
The invention has the beneficial effects as follows: this invention is widely used, be particularly suitable for various solid materials to gather gas sample, reusable, can vacuumize, easy to operate, simple in structure.

Embodiment
Embodiment, with reference to accompanying drawing, a kind of multifunctional gas sampling apparatus, comprise that bag 1 upper end is pressed into sealing empennage 3, both sides are pressed into edge sealing 2, a valve seat 4 is fixed at center at sealing empennage 3, it is characterized in that being provided with a guide hole B8 in a side of the valve seat upper cover 17 of valve seat 4, establishes annular chute 9 at valve seat 4 upper end cylindricals; In valve seat 4 upper ends, valve gap 7 is housed, the inner circle of valve gap 7 lower ends is provided with annular boss 10, and boss 10 is meshed with chute 9, is provided with valve gap pressing plate 6 in the middle of valve gap 7, one side of valve gap pressing plate 6 is provided with guide hole A5, and valve gap pressing plate 6 closely cooperates with the valve seat upper cover 17 on valve seat 4.The bag opening 15 of bag 1 lower end twists on hollow spool 13, clamps with internal clip 12, and the end of internal clip 12 is provided with clamping slot 16, is clipped in clamping slot 16 with the termination of external clip 14 in internal clip 12 outsides, and bag opening 15 is further fixedly clamped.The inside of bag 1 arranges two layers of folding line perforated film 11, its objective is that two films that solve bag 1 stick together the difficult problem of bleeding, and solid material is placed in, and two layers of folding line perforated film are middle can prevent that bag 1 is punctured.Internal clip 12 and external clip 14 all should adopt elasticity large, and the material that intensity is high is made, to ensure its clamping force.
When use, first solid material that will be detected is packed in bag 1 from bag opening 15, be placed in the middle of two layers of folding line perforated film 11, then opening closes bag opening 15, twist on hollow spool 13, roll up 180 °, bag opening 15 exceeds internal clip 12, first clamps with internal clip 12, and then is against the interior further clamping of clamping slot 16 with 14 two terminations of external clip.After sealing, rotate valve gap 7, make the guide hole B8 of the valve seat upper cover 17 of the guide hole A5 aligning valve seat 4 on valve gap pressing plate 6, can take out the gas in bag 1, or inwardly inflation.Will be by valve gap 7 Rotate 180s ° while closing, guide hole A5 and guide hole B8 are staggered.
Simple in structure, easy to operate.
