The specific embodiment
Further specify referring to figs. 1 through 4 couples of embodiment of the present utility model:
Embodiment:
This wellhead sampling device comprises screw mandrel end protecting cover 1, bearing support 2, bearing 3, protecting cover welding gear pin 4, four-way housing 5, trapezoidal screw 6, trapezoidal screw nut 7, sampling plunger 8, protecting cover 9, sample tap 10, dustproof protecting cover 11, exhaust valve component 12, breathes valve body 13, welding gear pin 14, protecting cover screw 15 and guide peg 16:
This sampler four-way housing 5 cylindrical shells are provided with oil-in 51 and oil-out 52 connecting pipeline, symmetry, the housing left side is provided with elastic positioning pin assembly 53, housing left part lower end is provided with sample export 54, and the housing left end connects dustproof protecting cover 11 by welding gear pin 14; Dustproof protecting cover 11 sidewalls are provided with the sample tap 10 of band protecting cover 9, connect in the end face centre bore to breathe valve body 13.
Four-way housing 5 right sides are provided with bearing 3 by screw connecting axle bearing 2 in bearing support 2 centre bores, and four-way housing 5 right-hand members are by protecting cover welding gear pin 4 connecting filament rod end protecting covers 1.
Connect sampling plunger 8 in the four-way housing 5, sampling plunger 8 left parts are provided with sampling cavity 81, sampling cavity 81 sidewalls are provided with the oil outlet 86 of fuel feed hole 82 and counter sample outlet 54, the plunger left side is provided with centre bore 87, plunger right part outer peripheral face is provided with annular chamber 84, and plunger axial center hole 83 inwalls are provided with gathering sill 85.
The sampling process of this wellhead sampling device is as follows:
1, lay down protecting cover 9 with special tool, elastic positioning pin assembly 53 is pushed up back release in four-way housing 5 end faces, the protecting cover 11 Rotate 180 degree that will prevent dust make sample tap 10 aim at sample export 54 downwards, again sample tap 10 are connected sampling bottle.
When 2, taking a sample, with special-purpose cranking bar rotary screw end protecting cover 1 and trapezoidal screw 6 rotations, pulling sampling plunger 8 is mobile reposefully to the right with the guide peg 16 of corresponding gathering sill 85; When the fuel feed hole 82 of sampling plunger 8 and oil-in 51 that oil outlet 86 is aimed at four-way housing 5 respectively and oil-out 52, crude oil enters sampling cavity 81.
