Technical Field
The utility model relates to a gaseous sampling device technical field specifically is a gaseous sampling device in petrochemical detects.
Background
In the process of oil field development, hydrogen sulfide gas and carbon dioxide gas are also produced to the ground along with oil well produced liquid and associated gas, according to the regulations of the engineering technology management center safety and environmental protection, closed sampling must be carried out on a wellhead flow and an external transportation flow, and a detection tube method is used for carrying out quantitative detection on the concentration of the oil well hydrogen sulfide. The on-site detectable sampling position comprises a wellhead sampling valve, a wellhead pressure gauge valve, a heating furnace gas distribution bag, a metering station metering separator gas outlet and a sleeve gas outlet.
The traditional sampling method for measuring the trace total sulfur content in the gas sample is generally an injector sampling method, namely, the injector is pricked into a rubber tube and inserted into a sample injection bag, a needle head is pulled out after a certain amount of gas sample is taken out and then the gas sample is input into a detection instrument for detection, however, the sample injection bag and the rubber tube are easy to leak gas and damage after the needle head is pricked by multiple times, the existing sample injection bag is generally large, and a lot of gas for one-time sample injection is remained after the sample injection is generally carried out, so that waste is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a petrochemical detects gaseous sampling device to solve and advance the problem that the sample bag damaged easily and extravagant gas.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a petrochemical detects gas sampling device, includes the intake pipe, the one end threaded connection of intake pipe has the gas-supply pipe, the sealed sampling gasbag that has cup jointed in other end fixed surface of intake pipe, the surface of intake pipe is provided with the outlet duct.
Preferably, a surface of the intake pipe is provided with a first shut-off valve.
Preferably, the surface of the air outlet pipe is provided with a second stop valve.
Preferably, one end of the air outlet pipe is provided with a connecting part, and the inner side of the connecting part is provided with positioning rubber.
Preferably, the inner side of the positioning rubber is connected with a joint of the sampler.
Compared with the prior art, the beneficial effects of the utility model are that: open the interior gas transmission of first stop valve gas-supply pipe and can pass through the intake pipe to gas transmission in the appearance gasbag, close first stop valve after being full of gas in the appearance gasbag, then will insert connecting portion through the inside extrusion of location rubber as the sampler and fix a position the sampler joint and seal, then open the second stop valve, press appearance gasbag gas and will get into inside the sampler through connecting portion through the outlet duct to this damage of avoiding appearance gasbag and accomplished quantitative determination simultaneously.
