Description
Technical field
This utility model belongs to well head device field, particularly relates to a kind of well head sampler.
Background technology
In oil extraction in oil field production process, needing the well head at producing well to arrange sampling valve, staff obtains production fluid sample by sampling valve
Product, in order to aqueous, detect containing parameters such as sand.It is not enough in use to there is some in existing sampling valve: 1, existing sampling valve is big
Mostly being common valve, operation is laborious and speed of operation is slow.2, existing sampling valve is when sampling, owing to pressure jump can occur splash existing
As, pollute environment, for preventing this phenomenon from occurring, sampling valve can only be opened a bit, causes sample rate slow.3, existing sampling valve with
The joint of tube inner wall is the most smooth, not only can hinder the flowing of crude oil, and can aggravate the erosion to valve stem end, accelerates valve rod end
The damage in portion.
Summary of the invention
This utility model provides a kind of well head sampler, with the problem solving to propose in above-mentioned background technology.
This utility model is solved the technical problem that and is realized by the following technical solutions: this utility model provides a kind of well head and takes
Sampling device, including oil pipe and sampling valve, sampling valve includes valve body and valve rod, and valve body is threadedly attached in the side of oil pipe, and valve rod passes
Valve body also stretches in oil pipe, and valve rod is hollow structure, and the two ends of hollow structure are respectively arranged with inlet opening and liquid outlet, when sampling valve is opened,
Inlet opening is internal with oil pipe to be connected, and liquid outlet connects with the cavity of valve inner, valve rod stretches to the one end in oil pipe and is provided with limited block A,
The other end of valve rod is provided with limited block B, is provided with spring between limited block B and valve body, and valve body is hinged with drive rod, limited block B
Being connected by connecting rod with between drive rod, the downside of valve body is provided with probe tube, and probe tube connects with the cavity of valve inner, on probe tube
It is provided with hand-operated valve.
On described limited block A, the side within oil pipe is provided with the curved surface overlapped with tube inner wall.It is provided with pressure on described valve body
Power table, manometric liquid feeding end connects with the cavity of valve inner.It is provided with sealing ring between two ends and the valve rod of described valve body.Institute
When the sampling valve stated cuts out, limited block A is in the groove on tube inner wall, is provided with sealing gasket between limited block A and tube inner wall.
The beneficial effects of the utility model are: this utility model changes the mode that existing sampling valve rotarily opens, then use by breaking
The mode that dynamic drive rod drives, quick action, sampling efficiency is high.The cushioning effect of the cavity in valve body avoids the generation of expulsion events,
Thus accelerate sample rate.The curved surface overlapped with tube inner wall it is provided with towards the side within oil pipe so that limited block on limited block A
The combination that A is smooth with tube inner wall, reduces flow resistance, also slow down the erosion to valve stem end, has delayed the damage of valve rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-oil pipe, 2-limited block A, 3-inlet opening, 4-valve body, 5-hand-operated valve, 6-valve rod, 7-drive rod, 8-connecting rod, 9-
Limited block B, 10-spring, 11-liquid outlet, 12-Pressure gauge.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
The present embodiment includes oil pipe 1 and sampling valve, and sampling valve includes valve body 4 and valve rod 6, and valve body 4 is threadedly attached in oil pipe 1
Side, valve rod 6 is through valve body 4 and stretches in oil pipe 1.It is provided with sealing ring between two ends and the valve rod 6 of described valve body 4.
Valve rod 6 is hollow structure, and the two ends of hollow structure are respectively arranged with inlet opening 3 and liquid outlet 11, when sampling valve is opened, and inlet opening
3 connect with oil pipe 1 inside, and liquid outlet 11 connects with the cavity within valve body 4.The valve rod 6 of hollow and the cavity in valve body 4 are all to pressure
Suddenly the release of power plays cushioning effect, it is to avoid the too fast precipitation of gas and the expulsion events that produces, thus accelerates sample rate.
Stretching to the one end in oil pipe 1 on valve rod 6 and be provided with limited block A2, the other end of valve rod 6 is provided with limited block B9, limited block A2
Effect with limited block B9 is to stop valve rod 6 to be deviate from valve body 4.Spring 10, spring 10 it is provided with between limited block B9 and valve body 4
After sampling valve is opened, play reset response, make sampling valve with quick closedown, and then sample rate can be improve.
Being hinged with drive rod 7 on valve body 4, be connected by connecting rod 8 between limited block B9 with drive rod 7, drive rod 7 and connecting rod 8 form
