Abstract
The invention discloses a self-sealing anti-theft sampling valve of an oil well. The self-sealing anti-theft sampling valve of the oil well comprises a shell body (1), a valve core (2), a valve seat (3) and a switch spanner (4). The self-sealing anti-theft sampling valve of the oil well is characterized in that the self-sealing anti-theft sampling valve of the oil well is cylindrical, the shell body (1) is in threaded connection with the valve seat (3) and is provided with a center bore (A) with three different bore diameters, the bore diameter of the middle of the center bore is larger than the bore diameters of the two ends of the center bore, a closed sealing tapered hole (E) is formed in the left side of the shell body (1), an open sealing tapered hole (D) and internal threads are formed in the right side of the shell body (1), the valve core (2) is installed in the center hole (A), and a right-angle sampling opening (B) is formed inside the shell body (1). The self-sealing anti-theft sampling valve of the oil well is novel in structure, easy to manufacture, convenient to operate, accurate in data entry, free of sealing ring and long in service life. The switch spanner is not easy to imitate, the anti-theft effect is good, oil and gas loss and environment pollution are avoided, and labor intensity of workers is relieved.
Description
Technical field
the present invention relates to the oilfield crude oil sampling apparatus, specifically a kind of oil well self sealss anti-theft sampling valve.
Background technology
in process of production, crude oil water containing chemical examination data is the daily production management of oil well and the necessary capsule information of oil field dynamic analysis to oilfield, thereby crude oil sampling is one of post workman routine work every day.The lawless person also often robs crude oil from sample tap, to oil field, causes serious economic loss, affects the normal production order in oil field.Through retrieval, " anti-theft sampling valve " and " oil well is exempted from the emptying sampling device ", 2 of total patents of invention, 24 of utility model patents, wherein " anti-theft sampling valve " patent No.: 200510040002.4, complex structure, cost is high; And " pollution-free sampling device for oil well " patent No.: 201120344441.5, workflow reengineering need be many with pipe fitting, and complicated operation has increased post workman's labour intensity, is unfavorable for promoting the use of.
Summary of the invention
purpose of the present invention is exactly in view of the foregoing defects the prior art has, and a kind of oil well self sealss anti-theft sampling valve is provided.
the objective of the invention is to be achieved through the following technical solutions:
the present invention includes: housing, spool, valve seat, switch knob.Its oil well self sealss anti-theft sampling valve is cylinder, housing is threaded with valve seat, be provided with three grades of aperture center holes, the intergrade aperture is greater than the aperture, two ends, left side is provided with closes the sealing tapered hole, right side is provided with opening encapsulation tapered hole and internal thread, and spool is housed in centre bore, in enclosure interior, is provided with the quarter bend sample tap.
spool in above-mentioned oil well self sealss anti-theft sampling valve is Pyatyi ladder cylinder and the superimposed body of closing O-ring frustum and the rectangular core tongue of round edge, the semicircle switch groove of chopped-off head, and the third level is provided with external screw thread, and the fourth stage is provided with the opening encapsulation frustum of a cone.
switch knob in above-mentioned oil well self sealss anti-theft sampling valve is the T-shape structure, and termination is provided with sleeve, and the sleeve inward flange is provided with switch pin.
the invention has the beneficial effects as follows: novel structure, easily manufacture, easy to operate, the admission data is accurate, without sealing ring, long service life, switch knob is difficult for imitated, good anti-theft effect, avoid oil, gas loss and problem of environmental pollution, alleviated post workman's labour intensity.
