Description

The utility model relates to equipment used in the operation of main pipelines and can be used in the oil and gas industry for receiving cleaning, diagnostic and other in-line projectiles from the main pipeline.

A known temporary placement device for receiving flow projectiles from a main pipeline contains a receiving chamber, including a housing, one end of which is equipped with an end valve, and the second end is equipped with an adapter to which a linear pipe is connected, piping made in the form of a bypass line with an outlet and a line pressure equalization, and at least one pressure relief unit. The piping and pressure relief unit are equipped with shut-off valves. The ends of the pressure equalization line are designed to be connected to the bypass line and the housing of the receiving chamber. The end cap cover is equipped with a locking device made in the form of a bayonet connection. The body of the receiving chamber is equipped with a signaling device for the passage of a flow projectile into the receiving chamber (according to patent RU148228, F17D 3/08, B08B 9/04, publ. 11/27/2014).

The disadvantage of this device is the inability to regulate the speed of movement of the flow projectile in the pipeline.

There is a known method for ensuring the mode of movement of a diagnostic projectile in an ethane pipeline, which includes moving the diagnostic projectile at a given uniform speed, introducing the diagnostic projectile into the launch (reception) chamber, replacing the air in the launch (reception) chamber with equalizing the pressure in the launch (reception) chamber, extending the diagnostic projectile from the launch (reception) chamber, impact on the design of the diagnostic projectile, movement of the diagnostic projectile by the force created by the pressure difference. To implement the method, it is necessary to connect to a parallel gas pipeline. All stages of work are carried out by mutual opening and closing of the corresponding taps. The valves also regulate the required pressure drop in the pipeline and maintain a given uniform speed of the flow projectile (according to patent RU2644430, F16L 55/26, F16L 55/46, F16L 101/30, published 02.12.2018).

The disadvantage of this method is the need to connect to a parallel gas pipeline as a source of pressure.

The closest technical solution is a method of ensuring the mode of movement of a diagnostic projectile in an ethane pipeline, including moving the diagnostic projectile at a given uniform speed, introducing a diagnostic projectile into the launch (reception) chamber, replacing the air in the launch (reception) chamber with equalizing the pressure in the launch (reception) chamber. , extension of the diagnostic projectile from the launch (reception) chamber, impact on the design of the diagnostic projectile, movement of the diagnostic projectile by the force created by the pressure difference. To implement the method, a mobile receiver unit is used, which creates additional conditions for smoothing pulsation and provides pressure equalization and the possibility of in-line diagnostics. All stages of work are carried out by mutually opening and closing the corresponding valves (according to patent RU2644429, F16L 55/46, published 02.12.2018).

The disadvantage of this solution is the need to use a mobile receiver unit, as well as the difficulty of ensuring the mutual operation of all taps when regulating process parameters.

The technical result of the proposed utility model is to provide the ability to regulate the speed of a flow projectile in a pipeline.

The specified technical result is achieved in that the temporary placement device for receiving flow projectiles from the main pipeline contains a receiving chamber, including a housing, one end of which is equipped with an end valve, and the second end is equipped with an adapter, to which a linear pipe with shut-off valves, piping, made in the form of a bypass line with an outlet and a pressure equalization line equipped with shut-off valves, one end of the bypass line is connected to a linear branch pipe, the second end of the bypass line is connected to a gas sampling unit located opposite the end valve, the end of the linear branch pipe and the end of the gas sampling unit are made with possibility of connection with the linear part of the main pipeline, characterized in that the bypass line has fittings designed to regulate the flow of the medium along the bypass line.

The utility model is illustrated by drawings, which show:

Fig. 1 - receiving device, front view;

Fig. 2 - receiving device, top view.

A temporary placement device for receiving in-line projectiles from the main pipeline (hereinafter referred to as the receiving device) contains a receiving chamber, including a housing 1, one end of which is equipped with an end valve 2, and the second end is equipped with an adapter 3, to which a linear pipe 4 is connected shut-off valves 5.

Adapter 3 is made eccentric. The adapter 3 ensures by its shape that the lower part of the camera body 1 is located for receiving at the same level with the linear pipe 4.

The receiving device also contains piping, made in the form of a bypass line 6 with an outlet 7 equipped with shut-off valves 8.

The receiving device contains two pressure relief units 9 and 10. The pressure relief unit 9 is located on the body 1 of the receiving chamber, and the pressure relief unit 10 is located on the linear pipe 4.

The receiving device includes a pressure equalization line 11, which connects the bypass line 6 to the housing 1 of the receiving chamber.

Pressure relief units 9, 10 and pressure equalization line 11 are equipped with shut-off valves 12.

The end cap cover 2 is equipped with a locking device made in the form of a bayonet connection.

One end of the bypass line 6 is connected to the linear pipe 4, and the second end of the bypass line 6 is connected to the gas sampling unit 13 located opposite the end valve 2 and connected to the main pipeline, for example, by welding or flanges. Branch 7 connects bypass line 6 to housing 1.

The bypass line 6 is equipped with shut-off valves 14 and 15. The shut-off valve 15 opens and blocks the gas flow along the bypass line 6 from the gas sampling unit 13. The shut-off valve 14 opens and blocks the gas flow into the linear pipe 4. The bypass line 6 is equipped with additional fittings 16, providing possibility of regulating the flow of medium through the bypass line. It is possible to combine the functions of shut-off valves 14 and 16 in one unit.

The end of the linear pipe 4 is configured to connect, for example, by welding or flanges with the linear part of the main pipeline, and the linear pipe 4 itself, from the side of the specified end, is equipped with a signaling device 17 for the passage of a flow projectile into the linear part of the main pipeline, for example, a lever one.

Shut-off valves 5, 8, 13, 14, 15 and 16 can be used, for example, ball valves or gate valves.

Application.

In the section of the main pipeline where a flow tool, for example a cleaning piston, is expected, a pipe reel is cut out with overall dimensions that make it possible to install a receiving device instead of the specified pipe reel.

The gas sampling unit 13 is connected to the end of the main pipeline obtained after cutting out the pipe spool, opposite the side from which the flow projectile is expected, by welding or flanges.

To the end of the main pipeline, obtained after cutting out the pipe spool and from the side of which the flow projectile is expected, a linear pipe 4 assembled with shut-off valves 5, adapter 3 and housing 1 of the receiving chamber is connected by welding or flanges.

After this, the bypass line 6, the outlet 7 and the pressure equalization line 11 are connected by welding or flanges.

After this, the bypass line 6, the outlet 7 and the pressure equalization line 11 are connected by welding or flanges, after which the receiving device is considered ready for operation.

The flow projectile is received as follows.

Gas is transported through the main pipeline and along the bypass line with open shut-off valves 14, 15, 16 and closed shut-off valves 5, 8 and shut-off valves 12 located on the pressure equalization line 11.

When the flow projectile approaches the receiving device, the shut-off valve 12 located on the pressure equalization line 11 is opened, and by partially opening, for example, the shut-off valve 12 located on the pressure relief unit 10, the receiving chamber is filled with the transported gas, smoothly creating pressure in it , equal to the pressure in the main pipeline.

Next, shut-off valves 14 located on the bypass line 6 from the side of the linear branch pipe 4 are closed, shut-off valves 5 and 8 are opened and gas is transported through the main pipeline through the receiving chamber, waiting for the flow projectile to enter it. In this case, by adjusting the fittings 16, it is possible to reduce or increase the gas flow along the bypass line and, accordingly, reduce or increase the speed of the flow projectile.

When a flow projectile enters the receiving chamber, in the case of using a lever indicator 17 for the passage of a flow projectile into the receiving chamber, its flag takes a vertical position. After the alarm 17 is triggered, open the shut-off valve 14 located on the bypass line 6 from the side of the linear pipe 4, close the shut-off valves 5, 8 and shut-off valves 12 located on the pressure equalization line 11, and release the pressure in the receiving chamber by opening the shut-off valve 12 located at pressure relief units 9 and 10.

A loading table 18 is installed opposite the end gate 2.

Open the end valve cover 2 with a locking device made, for example, in the form of a bayonet connection and remove the flow projectile onto the loading table 18.

After completing the operation of receiving the flow projectile, the receiving device is dismantled in the reverse order of assembly, and a new pipe spool is installed in its place.

Thus, the proposed technical solution provides the ability to regulate the speed of the flow projectile in the pipeline, and thereby makes it possible to achieve the stated technical result.
