Abstract
The utility model relates to an injector, in particular to a gas sampling injector with double needle tubes and double needles. A needle tube of the injector is divided into a left semicircular needle tube and a right semicircular needle tube from the middle by the aid of a partition plate, wherein the bottom of the left semicircular needle tube is connected with a short needle, and the bottom of the right semicircular needle tube is connected with a long needle. The injector can be used for injecting liquid without reacting with the gas while sucking the gas, so that negative air pressure is prevented, and possible errors of experiments are reduced.
Description
Technical field
The utility model relates to a kind of syringe, is specifically related to the crosspointer pipe double needle syringe that a kind of gas production is used.
Background technology
In the gaseous sample chemical examination, the gas that often uses syringe to extract in the airtight container is chemically examined.But when being to use the syringe extracting gases, can make internal tank produce negative pressure, this negative pressure can make extraneous air pass through in the slit entrained gas sample of container, thereby causes gaseous sample concentration to change, and makes experiment produce error.
Summary of the invention
The purpose of the utility model is that a kind of crosspointer pipe double needle syringe simple in structure is provided in order to solve existing issue; This syringe can accomplish that when extracting gases limit extracting gases marginal not goes into the liquid that does not react with gas; Thereby stop the formation of air negative pressure, reduce the error that experiment possibly exist.
The utility model is realized through following technical scheme: the crosspointer pipe double needle syringe that a kind of gas production is used; It includes common syringe, it is characterized in that: the needle tubing of described syringe is divided into left semicircle shape needle tubing and right semicircular needle tubing by dividing plate from the centre; The bottom of described left semicircle shape needle tubing is connected with the hour hand head; The bottom of described right semicircular needle tubing is connected with the minute hand head.
Described left semicircle shape needle tubing and right semicircular needle tubing top are sealed, and wherein leave the cylindrical shape aperture in the middle of the left semicircle shape needle tubing top; On the described left semicircle shape needle tubing needle handle is arranged, described needle handle is connected with the semi-circular shape piston; Described dividing plate has circular aperture near head portion.
Described dividing plate, left semicircle shape needle tubing and right semicircular needle tubing all adopt glass or plastic material; Described needle handle, hour hand head and minute hand head all adopt the stainless steel metal material; Described cylindrical shape aperture, semi-circular shape piston all adopt the water proof rubber material.
The utility model compared with prior art has following advantage: this syringe construction is simple; Practical, in extracting airtight container during gas, on one side extracting gases inject the liquid that does not react with gas on one side; Prevent to produce negative pressure of vacuum, prevent that air from sneaking in the airtight container.

Embodiment
As shown in the figure: the crosspointer pipe double needle syringe that a kind of gas production is used, it includes common syringe 1, and the needle tubing of described syringe 1 is divided into left semicircle shape needle tubing 3 and right semicircular needle tubing 4 by dividing plate 2 from the centre; The bottom of described left semicircle shape needle tubing 3 is connected with hour hand head 5; The bottom of described right semicircular needle tubing 4 is connected with minute hand head 6.
Described left semicircle shape needle tubing 3 is sealed with right semicircular needle tubing 4 tops, wherein leaves cylindrical shape aperture 7 in the middle of the left semicircle shape needle tubing top; On the described left semicircle shape needle tubing 3 needle handle 8 is arranged, described needle handle 8 is connected with semi-circular shape piston 9; Described dividing plate 2 has circular aperture 10 near head portion.
Described dividing plate 2, left semicircle shape needle tubing 3 and right semicircular needle tubing 4 all adopt glass or plastic material; Described needle handle 8, hour hand head 5 and minute hand head 6 all adopt the stainless steel metal material; Described cylindrical shape aperture 7, semi-circular shape piston 9 all adopt the water proof rubber material.
Described needle handle adopts stainless steel material; This material is immersed in for a long time and is not easy in the water to change; The hardness of this material receives the difficult generation deformation of masterpiece time spent greatly; The cylindrical shape aperture on described piston, left semicircle shape needle tubing top adopts the elastomeric material of waterproof, can effectively stop air and liquid flow after the effect of being squeezed of this material.
