DEVICE FOR INSTALLING WITNESS SAMPLES IN A PIPELINE WITH A MEDIUM UNDER PRESSURE

The utility model relates to devices used in the gas industry, in particular, in field gas condensate and corrosion studies of pipelines during their operation.

A device for inputting and outputting a sensor of a state of a medium from a pipeline, mainly with a pressure medium, comprising a body with a valve for shutting off its cavity, connected to a pipe channel, a sleeve installed in the upper part of the body and a rod connected to one end with its hole, the other end of which is threaded connected to a sensor holder connected by a seal to the body, the sleeve being rotatably mounted in the body, and x made on the mating surfaces of the sleeve bore and rod end Single thread (1).

A disadvantage of the known device, taken by us as a prototype, is the inability to use it simultaneously for sampling.

The objective of the utility model is to create a device for installing witness samples in a pipeline with a pressure medium with simultaneous sampling.

The task in the device for installing witness samples in a pipeline with a pressure medium containing a housing with a screw mechanism, an airtight cup mounted on a shut-off valve and a smooth rod, the upper end of which is connected to the screw rod, and on the lower end of which is mounted a holder with samples witnesses decided that in the upper part of the device connected to the sampling tool, made in the form of a pipe with a channel open on one side and connected to the axial channel of the device and ytym other storoMPKOO N 17/00

they are valves for sampling and venting, and the height of the internal cavity of the sealed cup is equal to the height of the holder with witnesses mounted on it.

The salient features of the claimed device for installing witness specimens in a pipeline with a pressure medium are:

- in the upper part of the device is connected a means for sampling, made in the form of a pipe with a channel open on one side and connected to the axial channel of the device and closed on the other side by valves for sampling and pressure relief;

- and the height of the inner cavity of the sealed glass is equal to the height of the holder with witnesses attached to it.

The claimed significant distinguishing feature is unknown to us from the patent and scientific and technical information and in accordance with this is “New.

The claimed device made working drawings and prepares a prototype. In this regard, the device declared by us meets the criterion of “Industrial applicability.

The claimed device for installing witness samples in a pipeline with a pressure medium is illustrated using FIG.

The device is made in the form of a screw mechanism installed in a housing with a gland assembly. The screw mechanism is designed to convert the rotational movement of the driving nut 1 into the translational movement of the spindle 2. For manual control of the device on the running nut 1 of the screw mechanism, a hub 3 with handles is attached using a key (not shown in Fig. 4). The stuffing box is used to seal the movable joint stem 5 and housing 6. The stuffing box consists of a stuffing box housing 7, packing 8, a pressure sleeve 9, a pressure flange 10 and studs 11. The stuffing box 7 is connected to the hermetic cup 12, OUTLET5 // W

-

the cell of the internal cavity of which corresponds to the height of the holder 13 with witness samples 14. The movement of witness samples 14 is carried out using a spindle 2, to the lower part of which a smooth hollow rod 5 and a holder 13 are attached with witness samples 14. The upper end of the spindle 2 is installed in the driving nut 1. To stop movement in the upper part of the spindle 2, a latch 15 is installed. As a locking element for the period of replacement of witness samples 14, a valve 16 is used, which, with the help of a welded fitting 17, is installed it is dumped on the pipe 18. Pressure relief in the glass 12 is carried out using valve 19. The valve 20 is used to take samples in the pipe 18. The flange 21 is used to connect the witness specimen 14 to the valve 16, and the valve serves to connect the welded fitting 17c with a valve flange 22.

A device for installing witnesses 14 works as follows. The device using a flange connection 21 is mounted on the valve 16. The valve 16 is opened. By turning the handle 4 to the right, the driving nut 1 is moved. The sliding spindle 2 is lowered, moving the smooth rod 5 and the holder 13, with the witness specimens 14 fixed on it. Thus, the holder 13 with the witness specimens 14 is installed in the pipeline 18 at the desired depth. In the lower part of the holder 13 through the Central hole enters the medium, which under the action of pressure in the pipe 18 rises along the hollow stem 5 to the valve 20. By opening the valve 20, the required amount of product is selected. By moving the holder 13 vertically, it is possible to take samples at different depths. When lifting witness samples 14, the handle 4 is rotated to the left and

spindle 2 rises. The holder 13 with specimen witnesses 14 is removed from the pipeline 18 and returned to the body of the glass 12. The valve 16 is closed. Using the valve 20 mounted in the housing of the glass 12, relieve pressure. The device is removed from the valve 16 and install goriL2b 3 // s / b

at the service site (not shown in FIG.). By turning the handle 4 to the right, the holder 13 with the samples 14 is pushed out of the glass 12. Sample witnesses 14 are replaced and by rotating the handle 4 the holder 13 with the samples of witnesses 14 is returned to its original position. The device is again mounted on the valve 16. The use of such a device allows you to install witness samples 14 and take samples in the pipeline 18, which is under pressure.

The claimed device for the installation of witness samples 14 in comparison with the prototype allows you to simultaneously take samples from the study of the corrosion activity of samples.
