13 cl, 7 dwg

This invention relates to a device intended for mounting and Dismounting the probe in technological pipelines, tanks, etc. as outlined in the restrictive part of paragraph 1 of the claims.

BACKGROUND of the INVENTION

There are some suggestions on mounting and Dismounting of the probes in technological pipelines, tanks, etc. Such probes are used to measure the extent of corrosion, pressure, temperature, etc. within the system used, for example, in the oil and gas industry and in the manufacturing industries. Along with fitting the probe can be installed in the pipe through the hole in the equipment to ensure contact with the medium to be processed in this process.

The Assembly and disassembly of the probes is preferably performed under normal operating conditions, which means that the system does not derive from work if necessary, replace or test probes. As for pipelines, then it supports the normal operating pressure and there is no need for the descent of the liquid/gas. This fact can significantly reduce maintenance costs.

A disadvantage of the known hydraulic and/or mechanical izvlekateljami is a possibility of leakage when mounting or Dismounting of the probes with what neseniem harm to the environment.

In the offshore oilfield and industrial pipelines and transport pipelines are placed on the seabed. The condition of the contents of such a pipeline requires monitoring and necessary mounting and Dismounting probes for maintenance and reconstruction, however due to various advantages it is desirable to use the apparatus with remote control (HELL). Using the work of divers on the seabed such depth can be dangerous and even impossible, and from the economic point of view, the more advantageous is the use of HELL. The reliability of such work must be high, because a leak can cause significant economic and environmental consequences.

The technology of the prior art relies heavily on mechanical principles, such as using threaded connections between izvlekateljami and the transmitter and between the pipe access and izvlekateljami, and the use of levers with mechanical actuator for opening and closing valves. Such mechanical operations are difficult to carry them through HELL.

Has conducted a number of research works aimed at reducing the number of operations and the replacement of some threaded connections on a more simple device. In the description of U.S. patent No. 3589388 (Haeline, 1971) described isolecithal pneumatically operated, designed for the extraction nozzle injector of the environment under high pressure. This design contains a ball valve, which when open creates a passage for the introduction of the nozzle of the injector. In addition, it contains partially hollow or tubular connection unit with two or three grooves for the separation of many fingers. Each finger is radially directed tongue, which is located in the hole for the needle of the injector. These fingers have elasticity, providing a connection to this port, through which the probe can be removed by izvlekateljami.

The disadvantage of using this system is the need to implement a screw connection in the radial direction of the pipe access for attaching the injector needle. This connecting device can be removed from the hole without the needle of the injector is active only when the propeller.

In the description of U.S. patent No. 4275592 (Atwood and others, 1981) described isolecithal that uses the fingers with the tabs, providing the extraction probe. It also shows a number of threaded connections. Illustrated isolecithal not suitable for replacement probes used in subsea pipelines.

In the description of U.S. patent No. 4002059 (Jeffers and others, 1977) p the Kazan isolecithal, designed for mounting and Dismounting of the probes with the control plates for determining the corrosive effect of technological pipelines. During operation of such a probe is firmly seated in the slots in the pipe access by means of a spring-loaded locking means located on the probe. Isolecithal can be moved down the probe by means of a cable containing a hook tool and rod-like body. Along sulcatas down the probe rod-like body is lowered through the hole in the upper part of the probe, allowing the release of a spring-loaded locking means. The probe can be lifted from the pipe access after the capture groove located at the top of the probe, shoulders gripping means.

The disadvantage of this sulcatas is the need for two different tools for Assembly and disassembly of the probe. In addition, for lowering and pulling of the probe required load and the cable. And this device is not suitable to work with HELL.

From the description of the patent Norway No. 317390 (CorrOcean, 2004) a device for mounting the probe in the process pipeline or process chamber, which is also not good to work with HELL.

The INVENTION

The main purpose of this invention is to provide a device for mounting and dem is ntage probes, which is suitable for use with HELL. This device should allow the retrieval and/or installation of the transmitter without interrupting operation mode. This device must contain a management tool locking tool for attaching the probe to the pipe access reliable and simple way.

In addition, it is important to establish a reliable seal between the probe and the pipe access. Another purpose of this invention is to provide a probe suitable for use with this device.

Description of the invention set out in paragraph 1 of the claims, and in paragraph 9 sets out the description of the probe, suitable for use with this device. In particular, preferred embodiments of the described in PP-8 and 10-13. See below for more description of this invention with reference to two variants of execution.

The probe 14 further comprises a Central tubular core 17, which is the measuring device 15 and which contains two outer sealing element to prevent leakage between the probe 14 and the pipe 12. The first element is a seal 19 type "metal-metal" in the form of a corrugated tube, and the second dual seal 21 of the polymeric material with an intermediate support ring 23. The seal 19 "metal-metal" is located inside the constriction 16 of the pipe 12.

Through the tubular core 17 is the cable from the measuring device 15 to the tubular casing 24 in which is located a printed circuit Board. The tubular housing 24 is attached to the receiving device 25, destined for HELL, and contains a connector 26 for cable 27 passing to the Central monitoring unit (not shown). The tubular housing 24 is attached to tubular core 17 by a nut 28, which can be removed manually repair after removal of the probe 14 of the pipe 10.

Outside the sealing means on the tubular core is a sleeve 29 with an outer flange 30 that is designed to capture ajknym tool as shown in figure 2. The inner end of the sleeve 29 has an outer flange 31, which when in the inner position is within the reach of an annular series of clamps 32 and enables them to move radially inward. When the sleeve 29 in the outer position of these clips are pushed outward into engagement with the annular groove 33 in the pipe 12, there is a fixation of the probe 14.

The sleeve 29 is held in the outer guide sleeve 34 having outer gripping flange 35. Guide sleeve 34 has a series of radial holes for clamps 32 and enters into engagement with the sealing means.

Upon release of the clamps 32 relative to the tube access probe can be removed together with the sealing means. Gripping the flange 35 on the guide sleeve made in accordance with the outer gripping flange 30 to provide the work with a tool to HELL. The outer position of the sleeve 29 in the open position indicated by the letter "O", and in the locked position - the letter "L".

The connector 26 can be detached from the chassis before removing the probe 14 and attached back when mounting the probe.

The locking sleeve 29 preferably is spring-loaded and locking spring presses the sleeve in a fixed position in which the clamps 32 are pushed out in the radial healthy lifestyles the Institute in the groove 33.

Figure 2 shows the working end of the clamping tool 36. The clamping tool 36 comprises a tubular gripping portion 37 with a number of gripping fingers 38, providing a pair of internal annular grooves 39 with a gripping flange 30 and the gripping flange 35 on the guide sleeve 34 at their adjacent location. Thus, the gripping portion 37 can move the outer gripping flange 29 in free position with subsequent extraction of the probe 14 from the process piping, as shown in figure 4. Outside the tubular gripping portion 37 is activating element corresponding to the element shown in figure 5.

Figure 3 and 4 shows isolecithal 40 with a clamping tool 36 on the inside. Isolecithal 40 includes two housings 50, 51 of the valve, the tube 41 and the clamping tool 36.

Each case 50, 51 includes a connecting means 42, 43 with hydraulic controls for attachment to the flange, ball valve 44, 45, internal clamping tool 36 and the inner threaded portion 46, 47 at the outer end of each valve. The connecting means 42, 43 includes an actuator 48, 49 in the form of a bushing with hydraulic control, which when moving to the pipe 12 and from her in the longitudinal direction of sulcatas moves the number of terminals 52, 53 respectively in the locked and open position. Isolecithal 40 also provides the channels for a regulated supply hydraulic fluid to the actuators 48, 49.

The ball valve 50, 51 may be of known construction, and its purpose is to close the passage to the technological pipeline 10 when the probe 14 is extracted from the pipe 12. The opening and closing of each ball valve is preferably hydraulically running from HELL with gripping elements 54, 55, located on the rotary shafts of ball valves. When the open position of the valves 50, 51 of the valve body creates a cylindrical cavity, providing the sliding of the internal tool 36 back and forth along the longitudinal axis of sulcatas 40.

The drive control of the internal valve is hydraulically to provide slide for some distance back and forth in the longitudinal direction of sulcatas 40, the purpose of which is discussed below.

Figure 5 shows the position of release of the connecting means 42, and the actuator 48 that is designed to lock and release the clamp 52. The connecting means 43 are made with appropriate design solution.

The following is a description of the method of connection and use of sulcatas 40. Isolecithal includes a housing 50 of the first internal valve designed to be attached to the flange 22 of the pipe 12 by means of a connecting means 42. The connecting element 56, which contains the reception of the first flange, similar to the flange 22 of the receiving device on the pipe 12, and a threaded portion at the opposite end, is connected with the inner threaded part 46 of the housing 50 of the first valve. Thus, the connecting means 43 on the housing 51 of the second valve can be attached to the receiving flange of this coupling element. In addition, the outer threaded part of the tube 41 sulcatas interact with the internal threaded part 47 of the housing 51 of the second valve. Therefore, the housings 50, 51 and the tube 41 is collected in a site that does not require threaded connections during Assembly and disassembly of the probe 14.

The following is a description of the use of this sulcatas for disassembly of the probe. First through HELL remove the connector 26 located in the outer end of the probe. Then isolecithal 40 is moved along the guide protective cap 20 to the flange 22 of the receiving device on the pipe 12. The body 50 of the inner valve is attached to the flange 22 of the receiving device by actuation of the actuator 48, located on the connecting means 42, for providing connection of the fixing means 52 with the flange 22. When this sealing element provides a tight connection. At this stage, the ball valves 50 and 51 are preferably closed. Then the ball valve open and move the wall tool 36 to the tube 14 until while the hooks of flexible gripping fingers grip the flange 30.

Then, the inner actuator is moved so as to cover the gripping fingers 38 to deter them from moving outward in the radial direction, and accordingly, the flange 30. Further increase the pressure in the tube 41 sulcatas to a value exceeding the pressure in the process line 10, to prevent the uncontrolled ejection of the probe 14 and possible damage to the equipment. By moving the internal tool 36 in the tube gripping fingers 38 are pressed on the flange 30 toward the flange 35 of the probe. In the sleeve 29 is not stalkivaetsja in the pipe, the clamps 38 are no longer under pressure, clamping them to the groove 33 in the pipe 12. The internal drive is extracted, while the gripping fingers grasp the flanges 30 and 35. Now the probe 14 is in the open position. By gradually lowering the pressure in the tube 41 sulcatas to a value below the pressure in the pipeline 10, the probe 14 is moved into the tube 41.

The ball valve 45 of the housing 51 of the outer valve cover, and process fluid splashed back into the process tube before closing the ball valve 44 of the housing 50 of the valve. The outer body 51 of the valve and the tube 41 with the internal tool 36 and the probe 14 is disconnected from the housing 50 by detaching the actuator 43 to the ex long while the clamps 53 will not weaken his grip on the adjacent flange.

Then install the new tube sulcatas with a new tube or cap and body of the new valve and further Assembly of the probe primarily operates in the reverse order of the above-described method.
