Abstract
An oil well antitheft sampling device comprises a joint (1), a valve housing (2), a valve spool (3), a sealing ring (4), screws (5), a bonnet (6), a screw plug (7), a socket spanner (8), a valve (9) and a sampling port (10). The oil well antitheft sampling device is characterized by being of a cylindrical structure; the joint (1) and the valve spool (3) which are in threaded connection are mounted in the center hole of the valve housing (2) from left to right sequentially, the valve spool (3) is connected with a center thread of the bonnet (6), the bonnet (6) is in threaded connection with the valve housing (2) and is positioned by the screws (5), the screw plug (7) is assembled at the center of the bonnet (6) to retain the valve spool (3), and the valve (9) and the sampling port (10) are arranged at the right end of the valve housing (2). The oil well antitheft sampling device is novel in structure, convenient for operators to sample oil, good in oil and water sealing effect, high in antitheft capacity, and capable of preventing loss of crude oil in oil wells, preventing environmental pollution and improving economic benefits of enterprises.
Description
Technical field
the utility model relates to oilfield well head admission oil sample valve anti-theft technique, specifically a kind of anti-theft oil well sampler.
Background technology
well head sampling apparatus is to open a hole on vertical conduit at present, by one section of diameter 20mm pipeline welding herein, at this pipe other end, install gate, during sampling, open the sluices, oil-water mixture in gate and pipeline flow into sample bucket, after sampling by closing gate.The drawback of this sampler maximum is non-anti-theft, after lawless person turns on sampling gate, can directly steal crude oil, even causes the large-area environment pollution in well site, has a strong impact on the normal generation in oily district and the economic benefit of enterprise." anti-theft sampler of oil well head " patent No. ZL201220388462.1 having designed, profit poor sealing performance, application life is short.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of anti-theft oil well sampler.
the utility model is realized by following technical proposals:
the utility model comprises: joint, valve body, spool, sealing ring, screw, valve gap, plug screw, box spanner, valve, sample tap.Its theft-proof sampler for oil wells device is cylindrical structure, valve body centre bore is equipped with joint, the spool being threaded from right to left successively, spool is threaded with the center of valve gap, valve gap is connected with valve body screw thread, and there is screw to locate, on plug screw, at the center of valve gap, spool is blocked, the right-hand member of valve body is provided with valve and sample tap.
valve body center in above-mentioned anti-theft oil well sampler is provided with three grades of shoulder holes, and left and right two ends are equipped with internal thread, and left end is also arranged with screwed hole, and right-hand member inside is provided with tapered hole.
spool in above-mentioned anti-theft oil well sampler is that three grades of multidiameter shapes connect structure, the secondary external screw thread that is provided with from a left side, and the third level is provided with three grades of sealing rings, and right-hand member is provided with cone.
anti-theft oil well sampler in above-mentioned anti-theft oil well sampler, is characterized in that: described sealing ring is " Y " RunddichtringO or " O " RunddichtringO.
box spanner in above-mentioned anti-theft oil well sampler is that double end is abnormally-structured, and one end coordinates with plug screw, and the other end coordinates with spool termination.
the beneficial effects of the utility model are: novel structure, and sampling operation is convenient, profit good seal performance, anti-theft capability is strong, effectively prevents oil well crude oil loss, prevents the pollution of the environment, and improves Business Economic Benefit.
Accompanying drawing explanation
the main TV structure schematic diagram of Fig. 1-the utility model complete section.
in figure, 1. joint, 2. valve body, 3. spool, 4. sealing ring, 5. screw, 6. valve gap, 7. plug screw, 8. box spanner, 9. valve, 10. sample tap.
The specific embodiment
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
the utility model is comprised of joint 1, valve body 2, spool 3, sealing ring 4, screw 5, valve gap 6, plug screw 7, box spanner 8, valve 9, sample tap 10.Its theft-proof sampler for oil wells device is cylindrical structure, valve body 2 centre bores are equipped with joint 1, the spool 3 being threaded from right to left successively, spool 3 is threaded with the center of valve gap 6, valve gap 6 is threaded with valve body 2, and there is screw 5 to locate, on plug screw 7, at the center of valve gap 6, spool 3 is blocked, the right-hand member of valve body 2 is provided with valve 9 and sample tap 10.
method of operating
first, joint 1 is welded on to the liquid flow export place opening on the vertical conduit of oil well.
secondly, with wherein one end of box spanner 8, lay down plug screw 7.
the 3rd, the inside of inserting valve body 2 with the other end sleeve of box spanner 8, coordinates with spool 3 terminations,
counter clockwise direction turnbarrel spanner 8, spool 3 is outwards done axial displacement along screw thread, and when the sealing ring on spool 3 leaves the fluid course of valve body lower end, box spanner 8 stops the rotation.
the 4th, sample bucket is placed in to the lower end of gate 9, open the sluices 9, profit enters in sample bucket.When profit gather enough after, the box spanner 8 that turns clockwise, until spool moves to foremost sealing surface place and tightens, closed shutter 9, loads onto plug screw 7 and tightens.
