Definitions

  • This invention relates toa sampling device and pertains more particularly to apparatus for drawing a sample of liquid from a pipeline.
  • the invention is directed to an apparatus for drawing samples of liquid from a line consisting of a horizontal, rectangular line section, at least one bushing which is positioned Itransversely and vertically in the line section the bushing wall being provided with a slot-shaped opening extending in an axial direction, of a plug arranged rotatably in the bushing and provided with a liquid discharge channel and a .slot-shaped opening extending in an axial direction, and of means for discharging liquid from the plug to a liquid collecting device.
  • the object of the invention is -to provide sampling apparatus which has the advantage lthat it enables a sample to be drawn, the analysis of which gives the maximum amount of information about the composition of the liquid in the line.
  • the construction according to the invention is characterized in that rthe wall of the bushing has two diametrical axial slots, and the plug is provided with a centra-l channel yand two diametrical axial slot-s or with one axial slot extending between points situated diametrically on the circumference of the plug, channels being present in the plug and ⁇ in the bushing which are so arranged that in the position of the plug in -which the slots of the bushing and plug coincide the liquid -from the line section can continue its course practically without obstruction, whereas in a position ofthe plug in which the slots do not coincide, viz, when the supply of liquid from the line section to the interior of the plug is cut oil, a liquid discharge from the interior of the plug to the liquid collecting device is released, communication between the upper part of the plug interior and the atmosphere being also established.
  • FIGURE 1 shows a longitudinal cross-section II-II taken -in the line section and FIGURE 2 shows a crosssectional View I-I taken on the 'line section.
  • FIGURES 3 and 4 show cross-sections III-III and IV-IV, respectively, of FIGURE 2.
  • a rectangular line section 1 is housed in a cylindrical section of pipeline 2 to which it is secured by means of plates 8 and is internally provided with a bushing 3 which is rigidly connected to the line section 1.
  • the bushing 3 is provided with two axial slots 4 which are diametrically arranged in the wall of the bushing v3a.
  • a second bushing 5 is positioned in the bushing 3 and is provided at one end with anotched edge 6.
  • the bushing 5 - is so positioned in bushing 3 as to be rotatable round the common longitudinal axis relative to the xed bushings 3. This may be done with the aid of a suitable spanner or wrench fitting the notched edge 6 (FIGURE 2) of the bushing 5 Likewise the bushing 5 is provided with two axial slots 7.
  • the bushing 5 is in the position shown in the iigures, viz, in the position in which the slots 4 and 7 are in register.
  • a bushing ⁇ 9 is inside the bushing 5.
  • the bushing 9 is so secured as -to be incapable ot rotation round 4its -longitudinal axis.
  • the wall of the bushing 9 is provided with slots 10 ⁇ which extend in an axial direction and are in register with the slots 7 in the bushing 5.
  • the bushing 9k is provided with a plug 12 which is rotatable relative to the bushing 9.
  • the plug 12 has a continuous axial slot 13.
  • the top of the plug 12 has a square wrench head 15 by means of which the plug 12 can be rotated.
  • the plug 12 can be rotated by hand,
  • the lower part of the bushing 9 has an axial channel 16.
  • the lower part of the plug 12 is provided with a radial channel 17 which is in communication with a central axialchannel 18l which is also provided in the plug 12.
  • the channel 18 in turn communicates with a channel 19 ⁇ in a cylindrical element 20, which is screwed in the bushing 5.
  • a hose or a line through which the liquid sample can be discharged may be connected -to the nozzle 21 which is secured in the channel 19.
  • the upper part of bushing 9 is provided with an axial channel 23, which is in communication with the atmosphere. The upper part of the bushing 9 is secured ⁇ at the top and locked against rotation by means of the nut 25 and the plate 26.
  • the bushing 3 may be provided -on both sides of the slot-s 4 with metal strips 27 (FIGURE 4) to ensure that the disturbance of the ilow of liquid in line section 1 is reduced to a
  • the apparatus operates as follows.
  • the plug 12 is rotated either manually or mechanical-ly to the position shown in Ithe figures.
  • a quantity of liquid remains in the slot 13 and since the channel 16 in the relative position of the plug 12 is in register with the slot 13, the liquid can llow away from the slot 13 to a collecting vessel (not shown) through the channels 16, 17, 18, 19, lthe nozzle 21 and the line connected thereto (not shown). Since in the said position of the plug 12 the channel 23 establishes cornrnunication between the slot 13 and the atmosphere the liquid will readily ow to the collecting vessel.
  • the channel 23 and the channel 16 are so positioned relative to each other that rotation of lthe plug 12 will establish communication between the slot 13 and the channel 16 before the slot 13 communicates with the channel 23. This is essential to ensure that the pressure in the slot 13 is released before the slot 13 is brought into communication with ⁇ the atmosphere through the channel 23.
  • the composition of the liquid in the collecting vessel may be analyzed so as to gain information on the composition of the liquid owing through the line.
  • the plug 12 may be continuously or intermittently driven, preferably by means o an electric motor. In this way a sample of the liquid can be automatically drawn from the line at predetermined intervals. Analysis of the samples drawn enables the composition of the liquid in the line to be determined at any time.
  • the apparatus described has the advantage ⁇ that the sample can be isolated and drawn Without the flow pattern of the liquid in the line being greatly disturbed. A great advantage is that thecomposition of the liquid ⁇ of the sample is ⁇ closely representative of the composition of the liquid in the line.
  • the apparatus according to the invention is particularly intended for use in large diameter pipelines (60 cm.) for the transport of crude oil over long distances, for instance from Ia pont of entry to a number of refineries situated inland. Since the amounts due for crude oil pumped into the line near the portv of entry have to be settled with the consumers at the other end of the line it is important that the percentage of water in the crude oil owing through the line should be determined as accurately as possible.
  • the apparatus according to the invention confirms to this requirement ⁇ and renders the use of settling tanks unnecessary.
  • the bushing 5 may be rotated in such a Way around its longitudinal taxis by means of a Spanner iitting the notched edge 6 provided at the end of the bushing 5 that the slots 4 and 7 are no longer in register Wtih each other.
  • This has the advantage Ithat the bushing 9 and the plug 12 may be dismounted, for instance for inspection, cleaning and repairs, While the -line remains in operation.
  • An apparatus for withdrawing a ⁇ sample from liquid flowing through a pipeline comprising a ir'st bushing xed to and extending transversely through the pipeline, said bushing having diametrically-disposed slots through the walls thereof;
  • a third bushing disposed within the second bushing and -l'ixed relative to the irst bushing, said third bushing having 'slots through fthe Walls thereof in alignment with the diametrically-disposed slots in the rst bush- 111g;
