Description

Technical Field

[0001] The invention belongs to the technical field of oil and gas gathering, transportation, storage and transportation, and in particular relates to an installation component of an instrument for measuring the temperature of a medium in a pipeline network and an online installation method thereof. Background Art

[0002] In crude oil storage and transportation equipment and ground gathering and transportation process pipelines, the medium flowing in the pipeline network needs to be routinely monitored. It is necessary to install a thermometer or an IoT temperature test instrument to measure the temperature of the medium in the pipeline network. The specification requires that the measurement point is the temperature of the medium in the middle of the pipeline network, so when installing the temperature measuring instrument, the instrument measurement point needs to be deep into the middle of the pipeline network.

[0003] Generally speaking, during the construction process, a temperature measuring instrument socket will be installed. When the temperature needs to be measured during production, the thermometer or temperature measuring instrument can be installed in the socket. However, during production, some thermometer sockets are leaking and damaged due to corrosion or other problems, or with the promotion and application of the Internet of Things, the number of thermometer sockets originally designed and installed in the process is small and cannot meet production needs. In this case, new sockets need to be installed on the pipe network or container device.

[0004] When installing a new thermometer socket, the system needs to be shut down, replaced, and depressurized before re-drilling and welding the hole for installation. This method poses safety risks during installation and also affects the normal operation of production. In some pipelines and devices where production conditions do not allow, the temperature measuring instrument socket cannot be installed in time, affecting data collection. In some production sites, the temperature measuring instrument is installed on the outer wall of the pipeline to collect temperature data. This temperature collection method causes a large deterioration in temperature data. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an installation component for measuring the temperature of the medium in the pipeline network and an online installation method thereof, which realizes online pressure punching installation without stopping production. The installation depth of the temperature measuring instrument jack meets the requirements of the specifications, and the online installation method meets the safety requirements.

[0006] The above-mentioned object of the present invention is achieved through the following technical scheme: an installation component of an instrument for measuring the temperature of a medium in a pipe network, comprising an anti-slip nut, a fixed sleeve, an instrument installation tube, a rubber seal, a seal compression gland, a first-level pressure isolation chamber compression plug, a copper sealing gasket, and a drilling member; wherein the fixed sleeve is welded to the outer wall of the measured pipe network at 45 degrees, the instrument installation tube passes through the fixed sleeve, the head of the instrument installation tube is located in the measured pipe network and is connected to the drilling member, the tail of the instrument installation tube is open and has a protrusion near the tail end, an anti-slip nut is provided at the protrusion, a first-level pressure isolation chamber compression plug is provided on the inclined side of the protrusion, a copper sealing gasket is provided between the first-level pressure isolation chamber compression plug and the fixed sleeve, a rubber seal is provided between the inner wall of the fixed sleeve and the outer wall of the instrument installation tube, and a seal compression gland is provided between the rubber seal and the first-level pressure isolation chamber compression plug.

[0007] Furthermore, the instrument mounting tube is a hollow tube structure.

[0008] Furthermore, an annular groove is processed on the outer surface of the instrument mounting tube.

[0009] Furthermore, the instrument mounting pipe is threadedly connected to the drilling member.

[0010] Furthermore, the fixed outer sleeve cavity is provided with an open hole lubrication cooling and debris storage cavity, a primary system pressure isolation cavity, and a secondary valve core closed high pressure isolation cavity.

[0011] The online installation method of the installation assembly of the above-mentioned instrument for measuring the medium temperature in the pipe network comprises the following steps:

[0012] 1. Fasten the drilling piece and the instrument installation pipe with threads, and pass the instrument installation pipe through the center of the fixed jacket;

[0013] 2. Move the drilling parts and the instrument installation pipe outwards, and weld the center line of the outer jacket to the center of the temperature measured pipeline at a 45° angle. The welding requires full welding and sealing;

[0014] 3. After welding, add transformer oil to the inner cavity of the fixed jacket. The amount added should be between 1 / 2 and 2 / 3 of the volume of the opening lubrication and cooling and drilling cuttings storage cavity.

[0015] 4. Add an annular rubber seal ring to the primary system pressure isolation chamber, and the total thickness of 3-5 rings should be controlled between 24-30mm;

[0016] 5. Install the sealing packing ring and packing gland, and control the screwing of the gland to more than 5 threads;

[0017] 6. Install the integrated mechanism of the instrument installation pipe and the drilling piece. Insert the drilling piece to the middle of the measured pipe network. Tighten the packing gland. Clamp the tail of the instrument installation pipe with a handheld brushless electric drill. Turn on the handheld brushless electric drill for a test run and adjust the packing gland to an appropriate tightness.

[0018] 7. Start the electric drill to start the hole drilling operation. After the wall is penetrated, continue to drill the instrument installation pipe to the predetermined depth. At this time, the conical valve core on the outer wall of the instrument installation pipe contacts the sealing surface of the valve seat.

[0019] 8. Finally, install the locking cap. The screwing of the locking cap generates pressure to achieve a tight fit between the valve core and the valve seat to achieve sealing, and provide a secure installation for the temperature measuring tube in abnormal high-pressure conditions such as high-pressure extrusion of the measured pipeline.

[0020] Compared with the prior art, the present invention has the following beneficial effects: the present invention realizes one-time completion of online pressure drilling installation without affecting production; eliminates the influence of installing the thermometer jack on the normal operation of the system; there is no risk of pipeline opening during the construction process, eliminating safety hazards; after the construction is completed, the secondary seal can withstand the high pressure inside the system, and is designed with a device to prevent high-pressure components from flying out.

[0025] Example 1

[0026] The present invention provides a matching installation component for measuring the medium temperature instrument in the pipe network, such as Figure 1As shown, the instrument installation pipe and the drilling part are fastened by threaded connection. The interior of the fixed sleeve consists of three chambers: the bottom drilling lubrication cooling chamber, the first-level system pressure isolation chamber, and the second-level valve core closed high-pressure isolation chamber. The top is connected to the anti-slip nut. Transformer oil is added to the drilling lubrication cooling chamber to provide cooling and lubrication for the drilling, and at the same time to accommodate metal debris during the drilling process. An annular rubber seal is added to the first-level system pressure isolation chamber to cooperate with the temperature instrument installation pipe. Under the pressure provided by the gland and the clamping plug, it provides sealing during drilling to prevent the medium in the system from overflowing. After drilling through the wall, the clamping plug is further tightened, and the clamping plug and the fixed sleeve are sealed through a copper sealing gasket. After drilling through the wall, the instrument installation pipe is inserted into the predetermined position, and the installation pipe is rotated to achieve threaded connection with the clamping plug. After tightening, the tapered valve core of the instrument installation pipe cooperates with the tapered hole of the clamping plug to achieve sealing. The anti-slip nut is connected to the fixed sleeve by threads to achieve the final high-pressure anti-slip function.
