Abstract
The utility model discloses a gas acquisition and backflow device of a sterilizing gas detector and relates to a gas detector. The utility model provides the gas acquisition and backflow device of the sterilizing gas detector, wherein the penetrability of the acquisition and backflow device can be enhanced, the phenomenon that an acquisition device can not be inserted into a sterilizing confined space can be prevented, the blocking of the acquisition device can be effectively prevented, the acquired data can be more accurate, stable and reliable, the gas backflow area is more uniform, the quality of sterilizing can be ensured, and the hand is not injured easily. The gas acquisition and backflow device is provided with an acquisition tube, a gas guide tube and a handle, wherein the front end of the acquisition tube is provided with a gas hole; the rear end of the acquisition tube is connected with the gas guide tube; and the handle is arranged at the connecting positioned of the acquisition tube and the gas guide tube.
Description
Technical field
The utility model relates to a kind of gas detecting instrument, especially relates to a kind of fumigating gas detector gas collecting and return channel.
Background technology
In the stifling processing procedure of various facilities, generally must carry out gas concentration and detect, detect data and be and judge the stifling whether qualified unique index of handling.In existing gas concentration testing process, the collection of fumigating gas is that a stainless steel intubate is directly inserted confined space, and the shortcoming of this way is often to cause intubate can't insert confined space, causes the stainless steel intubate to stop up easily; In addition, firmly excessive because of the testing staff, and make hand injured easily.
Notification number provides a kind of portable light interfere type to be exclusively used in the detector of phosphine gas for the utility model patent of CN2039844.This device is mainly become with the gas circuit set of systems by the optical system that is assembled on the housing.It is on the basis of existing optical interferometry structure, is improved and makes.The length of critical component-air chamber wherein, design according to the refractive index of phosphine gas and the difference of measurement range thereof, simultaneously the reading drum of optical system and the full scale scale value of graticule are changed accordingly, it is not only easy to operate, value is directly perceived, accurately, and can solve silo stifling during the quantitative measurement of phosphine gas concentration.
Summary of the invention
The purpose of this utility model is to provide a kind of penetrability that strengthens collection and return channel, prevent that collector from can't insert the generation of stifling confined space phenomenon, can effectively prevent the obstruction of collector, the data of gathering are accurate more, stable, reliable, can make the gas backstreaming area more even, guarantee stifling work quality, be not easy to take place hand injured fumigating gas detector gas collecting and return channel.
The utility model is provided with collection tube, wireway and handle, is provided with pore at the front end of collection tube, the back termination wireway of collection tube, and handle is located at collection tube and wireway junction.
Described collection tube can adopt stainless-steel tube.The described collection tube front end that is provided with pore preferably is pointed.Described wireway can be rubber tube.The back termination wireway of described collection tube, preferably the rear end of collection tube and wireway are spirally connected.
Compare with existing fumigating gas detector, the utlity model has following outstanding advantage:
1, because collection tube front end of the present utility model is pointed plug design, therefore can strengthen the penetrability of collection tube, prevent that fumigating gas detector gas collecting and return channel from can't insert the generation of stifling confined space phenomenon.
2, be provided with pore owing to gather the recirculatory pipe front end, therefore not only can effectively prevent the obstruction of collector, and increased air collection area and gas backstreaming area, make the data of collection accurate more, stable, reliable; Simultaneously, can make the gas backstreaming area more even, guarantee stifling work quality.
3, owing to be provided with handle, therefore make execute-in-place convenient, can prevent that not only collection and return channel from can't insert confined space, and can prevent that the testing staff from because of firmly excessive, making the generation of the injured phenomenon of hand.
