Description
Technical field
The present invention relates to a kind of sampling head device and using method thereof, specifically, relate to a kind of sampling head device that is used for various poisonous and harmful fluids at the sampling operation of production, analytic process, be widely used in industrial circles such as medicine, chemical industry and food.
Background technology
The analytical sampling device has in chemical industry, medicine and food industry very to be used widely, and existing sampling head adopts crosspointer structure connecting tube mostly, and its operation is comparatively complicated, and the processing of sampling head is comparatively complicated, and cost is higher.And because the bottleneck of crosspointer structural requirement sampling bottle is bigger, more difficult to the packing washer of bottleneck like this; Be easy to related O-ring seal during sampling operation and be pushed in the sampling bottle, therefore causing the sampling head of present use all is the crosspointer structure sampling head of import, and just needle gage is shorter than homemade sampling head.And, the present sampling head of crosspointer structure, during collected specimens, poisonous and harmful fluid residual in sampling head is difficult to clean, and environmental pollution is serious.Therefore, be badly in need of a kind of sampling head device that can be used for the poisonous and harmful sampling fluids.
Summary of the invention
The invention provides a kind of sampling head device, this sampling head device has three-port structure, has only a syringe needle, require less to the sampling bottle bottleneck, make things convenient for the processing of the packing washer of bottleneck, and can prevent the leakage pollution on the environment of residual sample in the sampling head, simple and safe operation.
In order to achieve the above object, the invention provides a kind of sampling head device with three-port structure, this sampling head device comprises:
Three-port structure, this three-port structure have the first one-tenth end, the second one-tenth end and the three one-tenth ends;
Be set in the sampling pipe in the described three-port structure, the first one-tenth end of an end and the three-port structure of this sampling pipe is fixing, and extend on the pipeline of wanting collected specimens; The other end of this collection tube passes the second one-tenth end of three-port structure, and extend in the sampling bottle by the sampling bottleneck, and the sample of collection is transferred in the sampling bottle by described sampling pipe;
Be nested with the gas sampling pipe in the sampling pipe outside, this gas sampling pipe is fixing with the second one-tenth end of three-port structure, and this gas sampling pipe only is nested with the end at sampling pipe, is not to be nested with fully in whole sample collection tube outside; One end of this gas sampling pipe extend in the sampling bottle by the sampling bottleneck, and its other end sealing is arranged on three-port structure inside; And,
Be arranged in the three-port structure and with the three one-tenth exhaust gas recycling tube roads that end is fixing of three-port structure, one end in this exhaust gas recycling tube road is communicated with the end of gas sampling pipe, and be not communicated with the sampling pipe of gas sampling pipe inside, its other end is communicated with gas recovery system; Gas in the sampling bottle enters gas recovery system through the exhaust gas recycling tube road and recycles by the end of gas sampling pipe.
The passage that gas sampling pipe and exhaust gas recycling tube road are formed not only plays the effect of reclaiming fluid sample steam in the collecting bottle, can also make collecting bottle internal pressure and atmospheric pressure balance, the sampling difficulty of avoiding the sampling bottle internal gas pressure to rise and cause.
One end of described sampling pipe is connected and fixed with the first one-tenth end bite type of three-port structure, and an end of described gas sampling pipe is connected and fixed with the second one-tenth end bite type of three-port structure, and the three one-tenth ends adopt bite type to fixedly connected with the exhaust gas recycling tube road.
The invention still further relates to a kind of using method of sampling head device, specifically comprise:
Sampling head device provided by the invention has only a syringe needle, require less to the sampling bottle bottleneck, make things convenient for the processing of the packing washer of bottleneck, and use this sampling head device with three-port structure, after sampling finishes, can feed nitrogen sampling head is purged, remove the sample raffinate of sampling head inside fully, can effectively avoid environmental pollution, simple and safe operation.
Description of drawings
Accompanying drawing 1 is the structural representation of three-way sampling head device of the present invention.
Embodiment
As shown in Figure 1, the present invention adopts a kind of sampling head device with three-port structure, and this sampling head device comprises:
Three-port structure 1, this three-port structure have the first one-tenth end 11, the second one-tenth end 12 and the three one-tenth ends 13;
Be set in the sampling pipe 2 in the three-port structure, the first one-tenth end of these collection tube 2 one ends 21 and three-port structure, 11 bite types are fixedly connected, and extend on the pipeline of sample to be collected, in order to collected specimens; The other end 22 of this collection tube 2 passes the second one-tenth of three-port structure 1 and holds 12, extend in the sampling bottle 5 by the sampling bottleneck; The sample of gathering is transferred in the sampling bottle 5 by described sampling pipe 2;
Be nested with gas sampling pipe 3 in sampling pipe 2 outsides, this gas sampling pipe 3 only is set in 22 those ends of collection tube 2, be not set in the outside of whole collection tube 2, this gas sampling pipe 3 is fixedly connected with the second one-tenth end 12 bite type of three-port structure 1, and an end 31 of this gas sampling pipe 3 extend in the sampling bottle 5 by the sampling bottleneck; The other end 32 sealings of this gas sampling pipe 3 are arranged on the inside of three-port structure 1, make its pipeline through hole be in closed state with the first one-tenth end 11 of three-port structure; And,
Be arranged in the three-port structure 1 and with the three one-tenth fixedly connected exhaust gas recycling tube roads 4 of end 13 bite types of three-port structure 1, one end 41 in this exhaust gas recycling tube road 4 is communicated with the end 32 of gas sampling pipe 3, and be not communicated with the sampling pipe 2 of gas sampling pipe 3 inside, its other end 42 is communicated with gas recovery system; Gas in the sampling bottle 5 enters gas recovery system through exhaust gas recycling tube road 4 and recycles by the end 31 of gas sampling pipe 3.
Because the present invention adopts the sampling head device with three-port structure, need only a syringe needle and both can finish, lower to the bottleneck seal request, and collected specimens finishes, and also can feed nitrogen and purge, and removes the residual sample in the pipeline, make that this device is environmentally friendly, safe.
