Description

The utility model relates to measuring equipment and is intended for input as well as for extraction of equipment (flow meters, sensors, sampling probes) into pipelines, tanks, separators, heat exchangers or other containers under pressure.

A sampling device for a pipeline is known (RF patent No. 2295715, G01N 1/10, March 20, 2007), comprising a housing with an stuffing box, a sampling tube with a partial location in the cavity of the housing, a shut-off valve at the end of the sampling tube, which is connected to the housing by a threaded pair between pipeline and stuffing box device, and the thread on the sampling tube exceeds the length of the mating thread on the housing by the value of the inner diameter of the pipeline.

The disadvantage of an analogue is the limited functionality of the device.

A device for sampling liquid from a pipeline is also known (RF patent No. 2262681, G01N 1/10, 20.10.2005), comprising a sampling tube mounted inlet towards the flow, a flange mounted on the pipeline, shutoff valves mounted on the flange, a chamber with an oil seal mounted on shut-off valves and having an outlet pipe with a flange, the outlet of the sampling tube goes into the chamber, and the sampling tube has a lifting and lowering mechanism, while between the pipeline and the shut-off valve a ring with the possibility of passing through it a sampling tube and containing a conical part interacting with a sleeve mounted on the sampling tube with the possibility of elastic movement, in addition, a support ring is mounted between the stop valves and the camera with the possibility of passing through it a sampling tube and containing a section made in in the form of a seat of a shut-off valve, and the sampling tube has a section made in the form of a slide valve of a shut-off valve interacting with the seat of the support ring at the lower work position than the sample probe element.

The disadvantage of an analogue is the limited functionality of the device.

The closest in technical essence and the achieved result to the claimed is a device for extracting equipment from the pipeline (RF patent No. 38394 G01F 1/58, 02/18/2004), in which the equipment (flow sensor) is rigidly and coaxially fixed to the end of the hollow rod, which is placed coaxially in the housing-lubricator, with the possibility of limited axial movement, the housing-lubricator is equipped with a seal radially sealing the hollow rod.

In the closest analogue, the case-lubricator is functionally a lock chamber. The disadvantage of the closest analogue is the limited functionality due to the need to dismantle the housing-lubricator (lock chamber) together with the installed equipment in case of need to change equipment. Also, the design of the considered case-lubricator does not provide the ability to enter into the pipeline equipment with various shapes and cross-sectional sizes. These design limitations of the closest analogue are related to the fact that the equipment introduced into the pipeline is installed directly into the loading hole of the lubricator housing (lock chamber), and the tightness between the equipment introduced into the pipeline and the lubricator housing (lock chamber) is provided by the radial seal of the loading opening.

The objective of the utility model is to expand the functionality of the device.

EFFECT: provision of the possibility of introducing into the pipeline and extracting from the pipeline equipment with various shapes and cross-sectional sizes without dismantling the lock chamber.

The problem is solved, and the technical result is achieved by the fact that in the device for input and extraction of equipment under pressure, containing a pipe mounted on the pipeline, shutoff valves, airlock with pressure relief valve and loading hole made with a radial seal, a device for axial movement of equipment , according to a utility model, a tubular probe with a flange, which allows external fastening of the equipment, and the device for axial movement of the equipment is made with the possibility of impact on the flange of the tubular probe.

The essence of the utility model is illustrated by the drawing, which shows a cross section of a device for input and extraction of equipment under pressure.

A device for introducing and removing equipment under pressure comprises a pipe 2 mounted on a pipeline 1, shutoff valves 3, a lock chamber 4 with a pressure relief valve 5 and with a loading hole 6 in which a radial seal is provided 7. In the loading opening 6 of the lock chamber 4 is installed with axial movement of the tube probe 8 with a flange 9, providing the possibility of external fastening of the equipment 10, and the device 11 for axial movement of the equipment 10 is made so that it acts on the flange 9 ribbed probe 8.

A device for input and extraction of equipment under pressure works as follows. The equipment 10 introduced into the pipeline 1, which is under pressure, is installed inside the tube probe 8 and fixed on the flange 9. Then, the stop valves 3 are opened, and using the device 11 for axial movement of the equipment 10 through the loading hole 6 with a radial seal 7 is introduced into the cavity pipe 1, after which the flange 9 of the tube probe 8 is fixed relative to the lock chamber 4. To remove the equipment 10 from the pipe 1, you need to release the flange 9 of the tube probe 8 from the lock chamber 4. Using Features 11 move the tube probe 8 in the axial direction, removing the equipment 10 with the tube probe 8 from the pipeline 1 and close the shut-off valve 3. After closing the valve 3, the excess pressure inside the lock chamber 4 is released through the pressure relief valve 5. Next, the equipment 10 is removed from the flange 9 tube probe 8. In this case, the tube probe 8 together with the lock chamber 4 remains on the pipeline.

So, the claimed utility model allows you to expand the functionality of the device, providing input into the pipeline (extraction from the pipeline) of various equipment through the same tubular probe of the lock chamber without dismantling the lock chamber.
