Natural gas collection jar of institutional advancement

The utility model provides a natural gas collection jar of institutional advancement, belongs to that the natural gas collects and diverging device technical field. Including converge a jar jar body, with converge jar tank connection's partial flow interface and natural gas transportation line connection, characteristics: it has first tensile draw interface, the first end -to -end connection that draws the first circular arc of the intersection's formation transition district of stretching the draw interface and converging jar tank body wall of the jar body, partial flow interface and first tensile draw interface outwards to extend towards the direction that deviates from jar body cavity on the collection jar body and corresponding to the position of partial flow interface, jar jar body that converges is gone up to extend has the tensile draw interface of second, the tensile draw interface of second with converge jar tank body wall's of jar body an intersection and form second circular arc transition district, the end -to -end connection of natural gas transportation line connection and the tensile draw interface of second. Show the flow resistance that reduces the natural gas by first, second circular arc transition district to being in operating condition, a collection jar body can not produce the noise that disturbs residents under.
