Description

 The invention relates to all industries and is intended for opening cylinders with unknown contents that are under pressure, if it is impossible to discharge them regularly and then remove the contents.

 A device is known for drilling the walls of housings and elements of products under pressure in order to communicate with their internal cavity (1).

 The device consists of three main parts: a clamp, a shutter and a tool. The clamp is designed to secure the device to the object being drilled and to seal the junction of the device with the latter. The clamp is fixed to the object using a chain tensioner. Sealing of the connection is carried out by a rubber sealing element installed inside the sleeve, by pressing them to the outer surface of the pipe with a threaded sleeve and a threaded nozzle of the valve body. The shutter is a high-pressure valve with a ball locking element. The shutter is equipped with a bypass system located on its body for communicating the device cavities to the ball (from the pipe side) and behind the ball (with the ball shutter closed) with each other and with the atmosphere, as well as to control the pressure in the device cavities. The tool is intended for the implementation of the pipe drilling process.

 The tool contains a spindle with a seat under the drill. Sealing the spindle on the outer surface is carried out by a set of seals. The spindle shank is located inside the pressure screw. However, the known device does not provide tightness with a possible rupture of the cylinder when it is opened, as well as the safety of personnel in connection with the need to be in the danger zone due to the lack of remote control, moreover, the issue of connecting the removal, neutralization and purge systems to the device has not been resolved cavity contents.

 The aim of the invention is the safe opening of cylinders with unknown contents that are under high pressure, followed by sampling of the contents, its removal and neutralization.

 This goal is achieved by the fact that in the perforation pressure chamber, consisting of a housing, a head, locking valves, perforation mechanisms, the housing is equipped with flanges for connecting the head and centering flange, two side bends for removal and two bends for placement of perforation mechanisms represented by cylinders placed in them with the possibility of reciprocating movement of the pistons and rods with punches, while the rods with punches during the perforation process are passed through the cavity for a valve, and the process of centering and securing the perforated cylinder in the pressure chamber is carried out using a centering flange having a channel for draining the contents from the pressure chamber and equipped with a socket for installing the cylinder, and a cover having a seat in its lower part for self-centering and fixing the perforated cylinder.

 The design of the punch chamber is shown in the drawing.

 The device consists of a cylindrical body 1, equipped with flanges 2,3 for connecting the head 4 and the centering flange 5, four side outlets 6,7,8,9 with four locking valves 10,11,12,13 and two perforating mechanisms mounted on them 14 ,fifteen. The head 4 consists of a cover 16 secured to the head 4 by means of a nut 17. The connection between the head 4 and the cover 16 is sealed by means of a seal 18.

 The centering flange 5 is provided with a channel 19 for draining contents from the pressure chamber and sampling using a tap 20. Perforations 14.15, used to perforate the cylinder 21, are attached to the bends 6.7. consist of cylinders 22.23 with pistons 24.25 inserted into them with the possibility of reciprocating movement and rods 26.27 with punches 28 passing during the perforation process through the cavity of the locking valves 6.7. The lateral branches 8.9 serve to remove the reagent and to purge the pressure chamber if necessary.

 The centering flange 5 is equipped with a socket for centering and installing the cylinder 21. The cylinder 21 is fixed in its upper part using the cover 16, which has a seat for self-centering and securing the cylinder in its lower part.

 The work of perforating mechanisms is carried out by supplying the working fluid from the hydroelectric station through pipelines (not shown in the diagram).

 The operation of perforation (puncturing) is as follows.

 After installing and securing the cylinder in the pressure chamber, it is tied with pipelines to the hydraulic station and crimped. Then, by supplying the working fluid to the piston cavity of one of the perforating mechanisms, the rod with the punch is fed forward and the cylinder wall is pierced, after which, by supplying the working fluid to the rod cavity, the rod with the punch is retracted. And then the operation is repeated using the second perforating mechanism.

 After making the punctures, a sampling and analysis of the contents of the balloon are performed. After which a decision is made on how to neutralize or destroy it.

 These issues, as well as safety requirements for work, are not considered by this description.
