Description

The utility model belongs to pipeline transport and can be used to launch intra-pipe means into pipelines, in particular industrial and inter-industrial gas pipelines, gas networks and gas pipeline outlets.

A known portable unit for starting pistons (КК1020080068379, МПК ВО8В 9/027,

EOSE 9/00, publ. 23.07.2008), which consists of a mobile platform on which a chamber for launching pistons is placed horizontally. The mobile platform has a lower part with a pair of wheels and an upper part on which the support is installed. A camera for starting the pistons is installed on the support of the mobile platform. A hose is connected to the chamber, which is used to pump liquid into the piston space. The camera is connected to an assembly previously attached to the pipeline, which contains three taps and a tee. To facilitate the connection of the camera to the pipeline in a narrow well, a hose made of elastic material is provided.

The disadvantage of this installation is the impossibility of its use, if the above-ground section of the pipeline from the place of its connection to the entrance of the pipe into the ground contains uneven fittings, corner fittings, adapters from a larger to a smaller diameter of the pipes. Also, this system is difficult to implement and cumbersome due to the presence of a mobile platform and three cranes.

The closest to the proposed device is a vertical installation for launching pistons (0511428360, МПК Е16И 55/46, ВО8В 9/055, Е16И 55/44, publ. 08/30/2022), which contains a vertical tubular chamber, which is closed with a lid, and a reduction for compression pistons

The feed line of the transported medium is connected to the vertical chamber by a pipe that contains a tap for feeding the transported medium into the piston space.

A vertically installed tubular chamber is connected to an assembly that contains a connecting coil - adapter, start valve, tee and feed line valve. The supply line leads to a tee, to one of the flanges of which is attached a pipe connecting this line to a vertical chamber.

The disadvantage of this installation is the complexity of its implementation, use and bulkiness, since the presence of a supply line requires the installation of additional pipeline fittings. Also, the supply line must be connected to the vertical tubular chamber, which must also be attached to the connecting coil. In addition, it is impossible to use the device in the presence of uneven angle fittings.

The task, to which the useful model is directed, is the development of a simple in execution, use and installation of a multi-functional device for launching intra-pipe means into a pipeline, the above-ground sections of which at the starting point contain uneven fittings, angle fittings, adapters from a larger to a smaller diameter of pipes, in which pistons can be destroyed. At the same time, the process of starting the piston should not involve the emptying of the pipeline from the transported gas.

To solve the problem set in the device for launching intra-tubular means into the pipeline, which contains a vertical tubular chamber with a shutter fixed to its upper end, a tee and pipeline fittings, according to a useful model, the tee is made in such a way that the length from the flange of the main tee to the axis the branch is equal to the length from the branching axis of the tee to the flange of the straight-through valve connected to it, while the tee contains a manometric fitting with a pressure gauge and a fitting for blowing, and the shutter is made in the form of a plug.

Two versions of the universal device for launching intra-pipe means into the pipeline are proposed. According to the first variant, the chamber for launching intra-tubular means is a tee, the branch of which performs the function of a supply line of the transported medium into the piston space, while a plug is attached to the upper end of the tee, and a straight-through tap is attached to its lower end. According to the second option, a straight-through valve is attached to the upper end of the tee, to which a mobile chamber for launching intra-tubular means is connected with a plug, to which a launch pipe with a launch valve is connected.

Installation of a tee as a pipeline outlet allows you to use it as a part of this pipeline in the mode of passing the transported product. Depending on the need, it can be used as a chamber for launching intratubular means or as a connection unit for vertical mobile chambers for starting intratubular means, for example, such as pistons made of hyperelastic material (silicone, polyurethane foam, elastic polymer composition), cuff or disc pistons. This avoids the involvement of additional means and materials, and also simplifies the pipeline cleaning process.

The design of the tee in such a way that the length from the flange of the main body of the tee to the axis of the branch is equal to the length from the axis of the branch of the tee to the flange of the equal passage valve connected to it, enables its universal use as a stationary chamber for launching intra-pipe means or as a connection node for a mobile chamber for launching intra-pipe means

Installation of a straight-through valve at the end of the tee allows you to cover the tee and fill it with an intra-tubular agent.

The manometric fitting allows you to remove air from the pre-piston space during storage of the intratubular agent, and the presence of a manometer makes it possible to determine the moment of the start of movement of the intratubular agent.

A purge fitting allows air to be removed from the chamber prior to starting the intratubular agent.

Thanks to the design of the shutter in the form of a plug, additional sealing and a complex mechanism for opening and closing the camera are not required.

The design of the device makes it possible to use a mobile chamber with a plug, which, for example, can be a container with a visco-elastic piston, and in order to push the piston out of the container into the pipeline, a start pipe with a start valve is connected to the plug.

To connect the device to the pipeline, it is necessary to dismantle a steeply bent outlet (elbow) or corner fitting in the place where its above-ground part passes into the underground part. If there is an adapter from a larger to a smaller pipeline diameter at the entrance of the pipeline into the ground, then it must be dismantled as well.

To the flange of the pipeline, into which it is planned to start the piston, the flange of the equal-pass start valve of the device is attached, and to the branch of the tee - the above-ground section of the pipeline. The device for launching intra-pipe means into the pipeline is also a node for connecting vertical mobile cameras. To do this, the tee must be turned 180" around the axis of the branch.

Thus, the universality of the design of the device allows it to be used on sections of gas pipelines, which, unlike main pipelines, are characterized by a variety of technological schemes and contain a large number of complications related to piston cleaning, including their start-up. These can be, for example, wells.

To explain the essence of the proposed technical solution in fig. 1 shows a general

From the view of the universal device for launching intra-pipe means into the pipeline, in fig. 2 - the scheme of connecting the device to the pipeline for starting intra-pipe means, in fig. C - a diagram of connecting the device to the pipeline for use as a node for connecting a vertical mobile chamber for launching pistons.

The device for launching intra-pipe means into the pipeline includes a chamber 1, which contains a tee 2, a manometric fitting Z with a valve 4 and a sample manometer 5, and a blow-out fitting 6 with a valve 7. One end of the chamber 1 is closed by a plug 8, and a straight-through start valve is attached to the other 9. The chamber 1 is connected to the flanges of the pipeline 10 by the flange of an equal-pass starting valve 9, such as a spherical valve, and by the branching flange of the tee 2. The intra-tubular medium 12 is stored in the chamber 1. Length | of the chamber body 1 from the plug 8 to the branching axis of the tee 2 should be equal to the length from the branching axis of the tee 2 to the flange of the equal passage starting valve 9. The branching of the tee 2 is connected to the pipeline 10, which contains the overlapping fitting 11.

The device for launching intra-tubular means into the pipeline can also be a node for connecting mobile cameras. To do this, the tee 2 is turned 1807 around the axis of its branching, while a vertical mobile chamber 13 is connected to the flange of the equal-pass start valve 9, which is located on top of the tee 2, through the adapter 14. The mobile chamber 13 is closed by a plug 15, to which a start pipe is attached 16 with a start valve 17.

The device for launching intra-pipe means into the pipeline can work in several modes: "Passing the transported product", "Launch of intra-pipe means", "Connection node of vertical mobile cameras for launching intra-pipe means".

The device works as follows. 1. Mode of passage of the transported product.

In this mode, stationary camera 1 works to pass the transported product.

Faucet 9 and overhead valve 11 are open. 2. Mode of starting the intratubular agent.

To start the intra-tubular means 12, it is necessary to cover the chamber 1 by closing the valve 9 and the cover valve 11, open the valve 7 of the blow-out fitting 6 and empty the chamber 1 of natural gas. In order to store the intratubular agent 12, it is necessary to remove the cap 8 and unscrew the manometer 5 from the manometric connector З and open the valve 4 to ensure the possibility of air exit from the pre-piston space during the storage of the intratubular agent. After that, store the intratubular agent 12 in the chamber 1 so that its rear end is below the branch of the tee 2. After that, screw the manometer 5 into the manometric fitting 3, connect the plug 8 to the body of the chamber 1. To remove air from the chamber 1 by blowing, it is necessary open the valve 11 and the valve 7 of the blow-out fitting 6. After the end of the blow-down, close the valve 7 and equalize the pressure in the chamber 1 with the pressure in the pipeline 10. This process is monitored with a pressure gauge 5. After equalizing the pressure, open the equal passage valve 9 and, under the pressure of the transported product, intra-pipe means 12 will start to move through the pipeline 10. 3. Mode of use as a node for connecting vertical mobile cameras for launching intra-pipe means.

In order for the device for launching intra-tubular means in the pipeline 10 to be used as a connection point for vertical mobile cameras, it is necessary to dismantle the plug 8 and turn the device to 1807 relative to the position in which it is in the "Starting the cleaning piston" mode (Fig. 3). After that, the straight-through tap 9 is closed and the vertical mobile camera 13 is connected, while the transportation of the product does not stop. The start-up of the intra-tubular means 12 is carried out by opening the tap 9 and the start-up valve 17. As a result, the pressure in the piston space will increase and the start-up of the intra-tubular means 12 will take place. After the process of starting the intra-tubular means 12 is completed, the equal-pass start-up valve 9 is closed, the vertical mobile chamber 13 is dismantled and the plug 8 is installed until the next launch of the intratubular means 12 using a vertical mobile camera 13.

The technical result of the application of the proposed device / launch of intra-pipe means into the pipeline is the simplification of the process of installation and execution and use of cameras for the launch of intra-pipe means into the pipeline due to its structural simplicity and manufacturability, as well as ensuring the possibility of cleaning and diagnosing the internal cavity of the pipelines, the above-ground sections of which are at the initial points contain uneven fittings, corner fittings, adapters from a larger to a smaller pipe diameter at the entrance of the pipeline into the ground. The ability to work in "Skip the transported product" mode allows you to avoid multiple installation and disassembly of the device. The 180" rotation of the device allows it to be used as a connection point for vertical mobile cameras for launching intratubular means, which provides versatility.

The device can be used to launch intra-pipe means into pipelines that are not equipped with the necessary device for this purpose, contain uneven fittings and adapters from a larger to a smaller diameter of pipes at the point of entry of the pipeline into the ground.
