Sectional sampler for reservoirs

FIELD: testing equipment.

SUBSTANCE: sampler relates to a sampling device in liquid and fluid condition, namely, to samplers for semi-automatic sampling along the entire height of the reservoir with oil products. The sectional sampler comprises a sampling column, a system of three-way valve control in the form of connecting traction rods and yokes connected into a parallelogram. Sections of sampling pipes are assembled by means of their installation into bores of three-way valves and are fixed by captive nuts with a seal. Besides, a worm gear is installed on the axis connected to a master yoke.

EFFECT: higher operational characteristics and service life of a sampler due to reduction of labour intensiveness of its assembly during installation and repair.

This solution relates to the field of extraction and preparation of samples for research, and in particular to a device for sampling liquid and fluid, namely a sampler for semi-automated sampling over the entire height of the tank with oil.

Famous sampler type RPS (Developer VNIIGENETIKA. Avenue "Devices and means of automation" ANTIPRION, Moscow, 1967).

The disadvantage of these samplers is the inability to obtain the actual composition of the product from the lower sections due to the overlap of the upper sections of the air.

The closest both in principle and technical device to the claimed solution is "a Sampler for sampling from tanks with petroleum products" (patent No. 2132994, IPC 6 F16N 1/10, 1999)containing the sample column, the system controlling the three-way valves in the form of connecting rods and rocker connected in a parallelogram.

Sample column consists of sections with a three-way valves, the number of which depends on the height of the tank. Sections are connected by flanges with gaskets for sealing.

The sampler by Pat. No. 2132994 has the following disadvantages:

- installation and repair sampler with flange connection of the sections is associated with high complexity and insufficient on what Einasto;

- when the height of the tank, a large number of sections and three-way valves, the high viscosity of the product on the lever of the control system, there is a considerable effort. These shortcomings reduce the operational characteristics of the sampler.

The objective of the proposed technical solution is the performance of the sampler by reducing the complexity of the Assembly (disassembly) of the sampler, and also reduce the effort of turning the taps at considerable height of the tanks.

This object is achieved in that the sampler containing the sample column, the system controlling the three-way valves in the form of connecting rods and rocker connected in a parallelogram, the section of the sampling tubes are installed in the grooves of a three-way valves and fixed coupling nuts with sealing, and on the shaft associated with the leading arm mounted worm gear. This solution is illustrated by drawings, where:

figure 1 presents a General view of the sampler;

figure 2 is a view along arrow A;

figure 3 - install sections of the sampling pipe, type In;

figure 4 - connecting rod and rocker, type B

The sampler contains sectional sample column 1, consisting of sections 2 sampling tubes installed in grooves three-way valves 3 and keeping the data coupling nuts 4 through the seal 5. The control device 6 is made in the form of a connecting rod 7 and the rocker arm 8 connected in a parallelogram, and the leading arm 8 is connected via a shaft 9 with the worm gear 10. The sampler is placed inside the tank 11 and is attached to his body sample column 1 in several places. Mandatory attachment are Luke 12 placed in the upper part of the tank 11 and the discharge device 13, is placed in the lower part of the tank 11. Through Luke 12 sampling column 1 communicates with the gas space of the tank 11. If the height of the sampling column 1 material, to protect it from the bias and to increase the rigidity, it is attached to the body of the tank 11 in a few places.

Does the sampler as follows.

In the initial state, the position of the handwheel worm gear 10 corresponds to the position: the three-position valves 3 blocked from the component present in the tank.

For sampling required handwheel worm gear 10 to rotate in the position of "Selection". All three-way valves 3 are rotated so that the component of the fuel in the level of this crane 3 received in the internal cavity of the sampling section of the column 1. Filled component of the sampling column 1 prepared for plum samples.

To drain the sample is bhodemon the wheel of the gearbox 10, the control unit 6 is put in position "Drain" of the sample. All valves 3 are rotated so that would be a single line for draining the sample component in all sections of the sampling column 1. This sample can be found in section clipped from the main component in the tank. Using common drain valve device 13 is draining the sample into the sample dish.

The advantage of the proposed sectional sampler for tanks is a fast and reliable Assembly during installation and repair, increasing the term of the sampler in working good condition, enhancing its performance.

The sampler sectional storage tanks containing sample column, the system controlling the three-way valves in the form of connecting rods and rocker connected in a parallelogram, characterized in that section of the sampling tubes are installed in the grooves of a three-way valves and fixed coupling nuts with sealing, and on the axis associated with the leading arm, mounted worm gear.

SUBSTANCE: invention relates to field of medicine, namely to pathomorphological diagnostics. To predict five-year long survival of patients with invasive breast cancer index of dispersion of tissue structures is determined as difference between maximal and minimal values of number of cancer structures and/or fractions of parenchymal or stromal component in microscopy at small magnification (100x) divided by quantity of vision fields in which said values were counted. If index of dispersion of tissue structures is lower than 1.6, five-year long survival of patient can be predicted with 95% probability, if its value is higher than 2.3, prediction of five-year long survival is unfavourable.
