Description

The utility model refers to the elements of technology used in the operation of the main pipeline, and can be used in the oil and gas industry for equipping temporary placement chambers for receiving treatment and diagnostic devices of various diameters from the main pipeline.

The technical problem solved by the claimed utility model is to improve the mechanical signaling device of the passage of the flowing projectile into the chamber for its reception from the main pipeline.

Known mechanical signaling device for the passage of streaming projectiles through the pipeline, including a housing, a connecting rod-pusher, a lower lever, a spring-loaded lever and a flag.

The principle of operation of such a signaling device lies in the fact that its body with all the other elements placed in it is mounted on a pipeline, into which a lower lever protrudes, which is moved vertically under the action of a flow shell passing through the pipeline.

Due to their high reliability, ease of maintenance, suitability for fixing the passage of a flowing projectile of any type without special alteration through pipelines of various diameters, safety for service personnel, such mechanical signaling devices have become widespread (Valueva N.A., Lavrent'ev M.A., Lvov S.L. Signaling device of the passage of purification and separation devices through main pipelines / Problems of automated control of oil industry facilities and oil product supply systems. Kiev, 1989. P. 54–58).

The main disadvantage of such a signaling device is the lack of the possibility of fixing the passage of streaming projectiles when using a receiving chamber of the same size on main gas pipelines of a smaller diameter, when using a receiving chamber that has an adapter in its structure, including at least two stages.

From the prior art, a mechanical signaling device adopted as a prototype of the passage of streaming projectiles into a chamber for receiving them from a main pipeline is known (RF Patent No. 150745 RU, publ. 02/27/2015), characterized in that the ability to act on the lower arm is provided by means of an arcuate bracket located at the end of the inner pipe directed towards the lower lever with the possibility of abutting one of its sides against the end of the outer pipe.

The disadvantages of the device are:

the complexity of the design of the device;

using welding to fasten the brackets inside the receiving chamber, which can damage the integrity of the chamber;

the inability to carry out (if necessary) a complete disassembly of the mechanism due to the use of welding;

the implementation of fixing the passage of the flow projectile in the receiving chamber, which has an adapter in its structure, including only one stage.

The objective of the claimed utility model is to improve the mechanical signaling device of the passage of the streaming projectile into the chamber to receive it from the main pipeline, leveling the above disadvantages.

The technical result of the claimed utility model is to fix the passage of a continuous projectile of any type and diameter without special alteration in the receiving chamber. The technical result is achieved due to the fact that a special extension attachment is attached to the lower arm with screws.

The essence of the technical solution - the installation of an extension nozzle on the lower arm of the mechanical signaling device of the passage of the flowing projectile into the chamber to receive it from the main pipeline - is illustrated by graphic materials, where figure 1 shows the placement of the extension nozzle on the lower arm of the mechanical signaling device, figure 2 - the design of the nozzle -extension (assembled), figure 3 - extension nozzle in disassembled form.

In this case, the mechanical signaling device of the passage of streaming projectiles into the chamber for receiving them from the main pipeline includes a housing 1, a connecting rod-pusher 2, a lower lever 3, a spring-loaded lever 4, a flag 5, an extension attachment 6.

The extension attachment consists of a base 7, a left stop 8, a right stop 9, two screws 10, a left bar 11, and a right bar 12.

The extension nozzle on the lower arm of the signaling device of the passage of streaming projectiles into the chamber for receiving them from the main pipeline works as follows: an extension nozzle 6 is installed into the chamber for receiving the streaming projectile moving along the main pipeline, the flow projectile, moving along the main pipeline, enters the camera for receiving and acts on the base 7, then the force is transmitted to the lower lever 3, which, in turn, drives the connecting rod-pusher 2 with the spring-loaded lever 4, after which the spring-loaded lever 4 disengages with the flag 5, while the flag 5 assumes a vertical position, signaling the passage of the streaming projectile into the receiving chamber. The length of the base 7 is selected taking into account the diameter of the receiving chamber used and the diameter of the streaming projectiles in such a way that when a streaming projectile (with a smaller diameter) enters the receiving chamber (with a large diameter), an effect occurs by engaging the base. Thus, the length of the base of the extension nozzle is selected taking into account the difference in the diameters of the receiving chamber and the flow projectile. With the described method of using a mechanical signaling device of the passage of a streaming projectile into the chamber for receiving it from the main pipeline, made on the basis of the proposed technical solution, the purpose of the latter is fully realized.
