It accepts；Since switch valve is the opening and closing for realizing access in the form of blocking, and the oil liquid in oil pipe has centainly
Pressure, therefore after switch valve opening, pressure abrupt release will lead to oil liquid splash, pollutes environment and staff, makes simultaneously
At the waste of oil liquid.
Utility model content
For above situation, for the defect for overcoming the prior art, the utility model provides a kind of production wellhead sampling dress
It sets, when effective solution current sampling the problem of oil liquid splash.
Its technical solution solved is a kind of production wellhead sampler, the first vertical tube including a both ends open, the
The side of one vertical tube is equipped with the second vertical tube of a sealing two ends, is communicated with out between the first vertical tube side wall and the second vertical tube side wall
Oil pipe is provided with a vertical blind hole on the inner bottom surface of the second vertical tube, is equipped with first plunger in blind hole, the first plunger with
One pressure spring is installed, the lower end of the second vertical tube is equipped with oil outlet, and the upper port of oil outlet is located at blind hole between blind via bottom
Closed on side wall and by the first plunger, lower port is located on the outer bottom of the second vertical tube, the first plunger move down can make it is fuel-displaced
The upper port in hole is opened；One transverse tube being located above flowline, the inner end of transverse tube and the are installed on the side wall of first vertical tube
One vertical tube communicates, and is equipped with second plunger that can be moved left and right in transverse tube, and the second plunger moves right, and to protrude into first perpendicular
In pipe.
The utility model can effectively avoid oil liquid expulsion problem when sampling, make the steady controllable outflow of oil liquid.
Detailed description of the invention

Fig. 2 is front sectional view when the utility model does not sample.
Fig. 3 is front sectional view when the utility model samples.
Specific embodiment
Further description is made to specific embodiment of the present utility model below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 3, the utility model includes first vertical tube 1 an of both ends open, the side of the first vertical tube 1
The second vertical tube 2 equipped with a sealing two ends is communicated with flowline 3 between 2 side wall of 1 side wall of the first vertical tube and the second vertical tube, and
Be provided with a vertical blind hole 4 on the inner bottom surface of two vertical tubes 2, first plunger 5 be installed in blind hole 4, the first plunger 5 with it is blind
One pressure spring 6 is installed, the lower end of the second vertical tube 2 is equipped with oil outlet 7, and the upper port of oil outlet 7 is located at blind hole between 4 bottom of hole
It is closed on 4 side wall and by the first plunger 5, lower port is located on the outer bottom of the second vertical tube 2, and the first plunger 5 moves down can
Open the upper port of oil outlet 7；One transverse tube 8 for being located at 3 top of flowline, transverse tube 8 are installed on the side wall of first vertical tube 1
Inner end communicated with the first vertical tube 1, second plunger 9 that can be moved left and right is installed, the second plunger 9 moves right in transverse tube 8
It is dynamic to protrude into the first vertical tube 1.
To realize moving left and right for the second plunger 9, the left end of second plunger 9 is connected with the threaded rod of a transverse direction
10,10 left end of threaded rod is stretched out outside transverse tube 8 and is threadedly engaged with the left end of transverse tube 8.
For convenient for rotating threaded rod 10, the left end of the threaded rod 10 is equipped with a runner 11.
The lower end of second vertical tube 2 is installed with an end cap 12 through screw thread；End cap 12 is covered when not sampling to be prevented
Pressure oscillation in second vertical tube 2 causes oil outlet 7 to open and leak.
To improve Extraction rate, the oil outlet 7 is uniformly distributed multiple in 5 excircle of the first plunger.
When the utility model is used, it needs to connect the first vertical tube 1 and accesses the outlet port of production pipe, when not sampling,
End cap 12 covers the lower end in the second vertical tube 2, and the first plunger 5 is located in transverse tube 8 and its right end does not extend into the first vertical tube 1, and first
Plunger 5 is located at upper under the action of its bottom pressure spring 6, and the side wall of the first plunger 5 closes the upper port of each oil outlet 7, this
When oil liquid is without hindrance out of first vertical tube 1 flows through；When needing to sample, sample bucket is placed on to the lower section of the second vertical tube 2 first,
Then back out end cap 12, then rotate Rotating wheel 11, make runner 11 drive threaded rod 10 rotation to make push the second plunger 9 to
It moving right, the right end of the second plunger 9 gradually protrudes into the first vertical tube 1, and cause the overflow section product of the first vertical tube 1 to reduce, first
Impedance at vertical tube 1 increases, oil liquid constricted flow, so that the oil pressure in the first vertical tube 1 of 9 lower section of the second plunger can be made to increase,
Oil liquid in second vertical tube 2 also increases with it, and oil pressure increase will push the first plunger 5 and the effect of pressure spring 6 is overcome to move downward, from
And it is gradually opened the upper port of each oil outlet 7, the oil liquid in the first vertical tube 1 can flow into the second vertical tube 2 through flowline 3, so
The second vertical tube 2 is flowed out by blind hole 4 and oil outlet 7 to flow into sampling tank；Second plunger 9 moves right more, the first vertical tube 1
Area of passage reduce it is more, oil pressure is raised more, then the first plunger 5 moves downward more, and the aperture of oil outlet 7 is opened
The amplitude opened is bigger, and Extraction rate is faster.
After the completion of sampling, rotating wheel 11 makes the second plunger 9 be gradually backed out the first vertical tube 1 to taking exercises, in the first vertical tube 1
Oil pressure be gradually reduced, the first plunger 5 moves upwards under the action of pressure spring 6 closes the upper ports of multiple oil outlets 7, then
Cover end cap 12.
This sampler uses the thinking of " it is thin that change, which is blocked up, ", the power that the pressure of oil liquid is opened as valve, with oil
Oil outlet 7 is slowly controllably opened in gradually rising for pressure, is flowed out oil liquid smoothly, is avoided traditional sampler in valve body
Pressure abrupt release causes the problem of oil liquid splash when unlatching, i.e., clean cleaning avoids pollution environment and staff, and keep away
Oil liquid waste is exempted from.
