Abstract
The utility model discloses a kind of gas collecting device, comprise the air induction hose that pin steps on inflating pump, connecting pin steps on inflating pump inlet end, the air-out hose that connecting pin steps on inflating pump outlet side, the band nut copper pipe be connected with air-out hose, the stop valve is connected with band nut copper pipe, and the collection ball that is connected and installed of stop valve.This gas collecting device have explosion-proof, efficiently, the advantage such as convenient, all gaseous sample can be collected under achieving low pressure or pressure-less state, and the length of the flexible pipe increased extends the position of sampling effectively, also can effectively collect for the gas in underground piping, also have easy to connect, low price, feature simple to operate, is suitable for extensive popularization.
Description
Technical field
The utility model relates to a kind of technical field of gas collecting device, particularly relate to a kind of be applicable to low pressure or pressure-less state under collect the gas collecting device of gaseous sample.
Background technology
Gas be a kind of invisible, flowing, be difficult to catch thing, therefore, gaseous sample need adopt ball gather.Such as, but ball sampling needs just can gather under a certain pressure, and the place of some normal pressures or low pressure cannot gather gaseous sample with ball: sewers, indoor gas, work-yard gas etc., very large limits range of application.General ball sampling, utilizes tongs to seal, gathered be sealed in or easily pollute when opening inspection.Especially some inflammable gases run into electrostatic and may blast, and damage present collecting work personnel.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome above-mentioned prior art, a kind of gas collecting device is provided, this gas collecting device have explosion-proof, efficiently, the advantage such as convenient, all gaseous sample can be collected under achieving low pressure or pressure-less state, and the length of the flexible pipe increased extends the position of sampling effectively, also can effectively collect for the gas in underground piping, also have easy to connect, low price, feature simple to operate, is suitable for extensive popularization.
The utility model solves the technical scheme that its technical problem adopts: a kind of gas collecting device, comprises the air induction hose that pin steps on inflating pump, connecting pin steps on inflating pump inlet end, the air-out hose that connecting pin steps on inflating pump outlet side, the band nut copper pipe be connected with air-out hose, the stop valve is connected with band nut copper pipe, and the collection ball that is connected and installed of stop valve.
Further, described air induction hose and air-out hose are rubber tube.
Further, described air-out hose is fixedly mounted by copper ring with the installation site of band nut copper pipe, and band nut copper pipe and stop valve are by nut fixing seal.
In sum, gas collecting device profit of the present utility model tramps with one's feet inflating pump as power resources, have explosion-proof, efficiently, the advantage such as convenient, all gaseous sample can be collected under achieving low pressure or pressure-less state, and the length of the flexible pipe increased extends the position of sampling effectively, also can effectively collect for the gas in underground piping, also have easy to connect, low price, feature simple to operate, is suitable for extensive popularization.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the gas collecting device of the utility model embodiment 1.
Detailed description of the invention
Embodiment 1
A kind of gas collecting device described by the present embodiment 1, as shown in Figure 1, the air induction hose 6 that pin steps on inflating pump 1, connecting pin steps on inflating pump inlet end, the air-out hose 6 that connecting pin steps on inflating pump outlet side, the band nut copper pipe 2 be connected with air-out hose, the stop valve 3 is connected with band nut copper pipe, and the collection ball 4 of 1L capacity that is connected and installed of stop valve is comprised.Pin is stepped on inflating pump and air induction hose and air-out hose and is all tightened sealing with nylon cable tie.
Further, described air induction hose and air-out hose are rubber tube.The specification of rubber tube is 2 × 9mm.
Further, described air-out hose is fixedly mounted by copper ring with the installation site of band nut copper pipe, and band nut copper pipe and stop valve are by nut fixing seal.The specification of nut is 7/16 inch, and the specification of the copper pipe of band nut is 1/8 inch, and the specification of copper ring is 9mm, and rubber tube is directly enclosed within copper ring, tightens sealing with nylon cable tie.
Its operation principle is: during collected specimens, gaseous sample is stepped on inflating pump compression movement by pin and is transported to right-hand member by left end air induction hose and gives vent to anger cartilage, now stop valve is for opening, and gaseous sample passes through band copper pipe and the stop valve of nut, and is finally retained in collection ball.Sampling terminates, and shuts stop valve, and the connection of right-hand member air-out hose with the copper pipe of band nut is separated.When detecting sample, the copper pipe of band nut is connected with institute survey instrument, opens stop valve, and gaseous sample in collection ball has been squeezed out detection.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
