RU85104U1 - CAMERA FOR STARTING AND RECEIVING OF FLOWERS OF CLEANING AND DIAGNOSTICS OF THE PIPELINE WITH THE END OF SANEMA BUTT - Google Patents

Abstract

A camera for starting and receiving in-line cleaning and diagnostic tools of a pipeline, comprising a camera body consisting of an expanded and nominal parts with an eccentric adapter between them and an end shutter, characterized in that the end shutter is self-sealing and is equipped with a means for attracting the shutter lid to the hole seat chamber, configured to remove the attractive force with increasing pressure in the chamber above a predetermined value.

Description

The full model relates to pipeline transport, namely, devices for starting and receiving flow means into the pipeline, and can find application in gas, oil and other industries using pipeline transport.

A device for starting and receiving flow means in a pipeline (Pat. RF No. 2103596, MKI F17D 3/08, application 04.11.96, publ. 01.27.98.), Containing start-up cameras equipped with an end shutter at one end, consisting of from the lid and hinged clamps pulled together by a screw and a tray for supplying and discharging flow means from it, and from the other end made with an eccentric adapter, pipe and branch, equipped with a screwed-in spark-proof material with a small end valve with a diameter of up to DN 200 mm inclusive for stocking flow redstv, wherein the connector is located on the horizontal axis of the chamber comprises a removable internally fixed in a predetermined position with outer bottom, mating with the inner surface of the retraction. The folding half-clamps of the end shutter of the camera are mounted on axes displaced vertically up and down relative to the horizontal axis of the camera.

This design of the shutter does not provide sufficient reliability fixing the shutter cover to the flange and reduces the reliability of the entire device.

Closest to the claimed solution is a camera for starting and receiving in-line means of cleaning and diagnosing pipelines (Pat. RF No. 70464, MKI B08B 9.053, declared 07.07.2006, published. 01.27.2008), containing a housing consisting of extended and nominal parts and an eccentric adapter between them, an end sector shutter with a hermetic locking cover actuator on the shutter body, which is a screw-nut pair located on the central axis of the expanded part of the chamber.

The disadvantage of this design is the high metal consumption of the end shutter and the complexity of its manufacture.

The objective of the invention is to reduce the metal consumption of the device for starting and receiving in-line means of cleaning and diagnosing pipelines, increasing the reliability of fixing the cover to the flange.

This goal is achieved by the fact that in the chamber for starting and receiving in-line means for cleaning and diagnosing pipelines, consisting of extended and nominal parts and an eccentric adapter between them, the end valve is self-sealing due to overpressure inside the chamber according to patent No. 27666 class. F16L 45/00 dated 10/29/2002, "End lock" Sanema ", which expired on 10/29/2007

Figure 1 shows a General view of the camera launch and reception in section; figure 2 is a General view of the shutter.

The camera for starting and receiving cleaning and diagnostic tools contains a nominal part 1 (Fig. 1) connected to the pipeline, an eccentric adapter 2, an expanded part 3, an end shutter 4 (Fig. 2) with a hinged lid 5 in contact with the camera seat from the inside. The end shutter is equipped with means 6 for attracting the cover 5 to the seat of the hole of the expanded part 3 of the camera, which creates the primary force of pressing the cover 5 to the seat of the hole of the expanded part 3 of the camera.

The tool 6 is made in the form of a half loop 7 mounted outside the camera with the possibility of moving it with a screw pair, one half loop 7 is installed on one end of the screw, and a steering wheel 8 is installed on the other end. The half loop 7 interacts with the half loop 9 mounted on the cover 5. B in the operating position shown in FIG. 1, the cover 5 fits snugly against the seat of the opening of the expanded portion 3 of the chamber.

It is most advisable to make the lid 5 convex inside the chamber, since this form provides the greatest strength of the lid 5 at a significant pressure of the working medium in the chamber.

The launch and reception camera operates as follows.

With the lid 5 of the shutter open, the necessary work is carried out to stock up the cleaning and diagnostic agents or to remove them. For this purpose, with the help of a reserve device, cleaning and diagnostic tools are introduced into the expanded part 3 of the housing of the launch chamber and they are advanced to the nominal part 1 of the housing. After that, remove the backup device from the expanded part 3 of the housing of the launch chamber. Pull the shutter cover 5 to the seat of the hole of the expanded part 3 of the camera. Cap 5 is seized by engaging half-loop 7 with half-loop 9. Rotating the steering wheel 8, press the cap 5 to the camera seat with a force sufficient for primary sealing of the chamber with cap 5. Open the linear valve on the pipeline and the product supply fitting into the chamber.

With increasing pressure inside the chamber, a force acts on the lid 5 due to the pressure drop inside and outside the chamber. As a result, the cover 5 is pressed against the seat of the expanded part 3 of the camera. The higher the pressure in the chamber, the stronger the cover 5 is pressed against the seat, while the interaction force of the half loop 7 and half loop 9 decreases and with a certain pressure inside the chamber, they exit the interaction. The end shutter reliably locks the trigger chamber. Under the pressure of the product, the cleaning or diagnostic agent enters the pipeline and moves through the pipeline to the receiving chamber, where it is removed through the same valve.

Thus, all the while the pressure is maintained in the chamber, the value of which is higher than the set value, the lid is pressed to the seat of the chamber opening due to overpressure inside the chamber, and the degree of lid compression is proportional to the pressure inside the chamber, which increases the tightness of the chamber and its reliability .
