Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction and transportation, and in particular to a fixing device for an antifoaming agent nozzle. Background Technology

[0002] In natural gas extraction wells, the foaming process can remove liquid from the well, thereby improving gas extraction efficiency. After adding foaming agent, the extracted material needs to undergo defoaming treatment. Currently, defoaming of the extracted material is achieved by injecting defoaming agent into the natural gas transmission pipeline using an injection pump. By installing nozzles on the defoaming agent injection pipeline and extending the nozzles into the natural gas transmission pipeline, the nozzles spray defoaming agent in a jet manner to remove foam.

[0003] However, the nozzle is fixedly connected to the defoamer injection line. The nozzle extends into the natural gas pipeline from the end plate of the natural gas pipeline. The defoamer injection line is fixedly connected to the end plate. Therefore, when the nozzle or the defoamer injection line becomes blocked, the natural gas pipeline needs to be depressurized and shut off before the nozzle or the defoamer injection line can be cleared. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where the natural gas pipeline needs to be depressurized and shut off before it can be cleared after the nozzle or defoamer injection pipeline is blocked, and to provide a device for fixing the defoamer nozzle.

[0005] This utility model provides a fixing device for a defoamer nozzle, comprising:

[0006] An end plate for connecting a natural gas pipeline, the end plate having a through hole;

[0007] The valve body is connected to the end plate and communicates with the through hole;

[0008] A connecting pipe, one end of which is detachably connected to a defoamer injection line, and the other end of which is equipped with a nozzle;

[0009] The connecting pipe is fitted with a sleeve, and the connecting pipe and the sleeve can be displaced relative to each other. The connecting pipe and the sleeve are in communication. The sleeve is detachably connected to the valve body. A sealing element is provided inside the sleeve, and the sealing element is slidably connected to the connecting pipe. The nozzle can pass through the sleeve and the valve body to enter the natural gas pipeline.

[0010] This utility model discloses a fixing device for an antifoaming agent nozzle. A through hole is provided on the end plate, connecting the through hole to the valve body. A connecting pipe connects a natural gas transmission pipeline and an antifoaming agent injection pipeline. A nozzle is installed at the end of the connecting pipe to disperse the antifoaming agent. The connecting pipe passes through the valve body and the end plate, allowing the nozzle to enter the natural gas transmission pipeline. The nozzle can be inserted into or removed from the valve body by utilizing the displacement between the sleeve and the connecting pipe. Closing the valve body isolates the natural gas transmission pipeline and the antifoaming agent injection pipeline. The sleeve and valve body are detachably connected, and the connecting pipe and antifoaming agent injection pipeline are also detachably connected. The connection allows for quick disassembly of the connecting pipe, enabling operators to unclog the nozzle and defoamer injection line. The valve body design prevents pressure reduction and shutdown of the natural gas pipeline, ensuring its normal operation and improving natural gas extraction and transportation efficiency. The sleeve and connecting pipe are sealed with a sealant to prevent oil and gas leakage. This invention provides a defoamer nozzle fixing device that allows the connecting pipe to be adjusted out of the valve body. With the valve body closed, the connecting pipe and nozzle can be disassembled to unclog the nozzle and defoamer injection line, ensuring the natural gas pipeline operates normally under pressure.

[0011] Preferably, the sleeve is threadedly connected to the connecting pipe, and the connecting pipe is capable of axial displacement along the sleeve.

[0012] The threaded connection allows the connecting pipe to extend into or retract from the valve body when the sleeve and the threaded connecting pipe rotate relative to each other, thereby allowing the nozzle to enter or exit the natural gas pipeline, facilitating the opening or closing of the valve body. The threaded connection also ensures a tight connection between the sleeve and the connecting pipe, making it easy to seal the gap between them.

[0013] Preferably, the connecting pipe is provided with a first connecting part, which can be connected to the wrench clamp.

[0014] The wrench is held in place on the first connecting part, which makes it easy to rotate the connecting pipe and change the relative position between the connecting pipe and the sleeve.

[0015] Preferably, the end of the sleeve is provided with an internal thread, the outer wall of the connecting pipe is provided with an external thread, and the end of the sleeve is threadedly connected to the connecting pipe.

[0016] The sleeve is threaded to the connecting pipe at its end, with sufficient space reserved inside the sleeve to facilitate displacement of the connection part.

[0017] Preferably, the sleeve is threadedly connected to the valve body.

[0018] It facilitates the installation and removal of the sleeve on the valve body, ensuring a seal between the sleeve and the valve body.

[0019] Preferably, the sleeve is provided with a second connecting part, which can be engaged with a wrench.

[0020] By providing a second connecting part, the sleeve can be easily rotated, making it easier to install or remove the sleeve from the valve body and facilitating relative displacement between the sleeve and the connecting pipe.

[0021] Preferably, the nozzle is detachably connected to the connecting pipe.

[0022] When only the nozzle is clogged, the defoaming equipment can be quickly restored to operation by replacing the nozzle.

[0023] Preferably, the sealing element includes an annular structure, the connecting pipe passes through the annular structure, the annular structure abuts against the connecting pipe, and the annular structure abuts against the sleeve.

[0024] The connecting pipe passes through the inner ring side of the annular structure, allowing the outer ring side of the annular structure to fit and abut against the inner wall of the sleeve, and the inner ring side of the annular structure to fit and abut against the outer wall of the connecting pipe, thereby ensuring sealing performance. The annular structure is usually made of rubber.

[0025] Preferably, the sleeve is provided with a first limiting ring and a second limiting ring, the first limiting ring and the second limiting ring are spaced apart to form a limiting groove, the annular structural member is disposed in the limiting groove, the annular structural member abuts against the first limiting ring, and the annular structural member abuts against the second limiting ring.

[0026] The ring structure is limited by a limiting groove formed by the first limiting ring and the second limiting ring, which improves the sealing effect of the ring structure.

[0027] Preferably, the connecting pipe is provided with a connecting block, the connecting block is rotatably connected to the connecting pipe, and the connecting block is used for detachable connection with the defoamer injection pipeline.

[0028] The connecting block is rotatably connected to the connecting pipe, making the connecting pipe easy to rotate and facilitating its installation and adjustment.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. A fixing device for an antifoaming agent nozzle of this utility model includes a through hole on an end plate, which communicates with a valve body. A connecting pipe connects a natural gas pipeline and an antifoaming agent injection pipeline. A nozzle is installed at the end of the connecting pipe to disperse the antifoaming agent. The connecting pipe passes through the valve body and the end plate, allowing the nozzle to enter the natural gas pipeline. The nozzle can be inserted into or removed from the valve body by utilizing the displacement between the sleeve and the connecting pipe. Closing the valve body isolates the natural gas pipeline and the antifoaming agent injection pipeline. The sleeve is detachably connected to the valve body, and the connecting pipe is detachably connected to the antifoaming agent injection pipeline. The disassembly connection allows for quick removal of the connecting pipe, enabling operators to unclog the nozzle and defoamer injection line. The valve body design prevents pressure reduction and shutdown of the natural gas pipeline, ensuring its normal operation and improving natural gas extraction and transportation efficiency. The sleeve and connecting pipe are sealed with a sealant to prevent oil and gas leakage. This utility model's defoamer nozzle fixing device allows for adjustment of the connecting pipe to detach from the valve body. With the valve body closed, the connecting pipe and nozzle can be disassembled to unclog the nozzle and defoamer injection line, ensuring the natural gas pipeline operates normally under pressure.

[0031] 2. This utility model provides a fixing device for a defoamer nozzle. By shutting off the valve body, the defoamer injection pipeline is isolated from the natural gas transmission pipeline, preventing maintenance of the defoamer injection pipeline and nozzle from affecting the operation of the natural gas transmission pipeline. The device allows for detachable connection between the connecting pipe and the defoamer injection pipeline, and detachable connection between the sleeve and the valve body, enabling operators to quickly unblock the nozzle and defoamer injection pipeline. The relative displacement between the sleeve and the connecting pipe allows the nozzle to enter or exit the natural gas transmission pipeline, and the valve body to be shut off. The sealing element prevents oil and gas leakage, improving maintenance efficiency and natural gas production efficiency, and possesses significant economic and practical value.

[0043] Example 1

[0044] like Figures 1-3 As shown, a fixing device for an antifoaming agent nozzle consists of a valve body 2, a connecting pipe 4, and an end plate 1 for connecting to a natural gas pipeline.

[0045] The end plate 1 is provided with a through hole 8;

[0046] Valve body 2 is connected to end plate 1, and valve body 2 is connected to through hole 8;

[0047] One end of the connecting pipe 4 is detachably connected to the defoamer injection line, and the other end is equipped with a nozzle 9;

[0048] The connecting pipe 4 is fitted with a sleeve 3, and the connecting pipe 4 and the sleeve 3 can be displaced relative to each other. The sleeve 3 is connected to the connecting pipe 2. The sleeve 3 is detachably connected to the valve body 2. The sleeve 3 is provided with a sealing element 10, and the sealing element 10 is slidably connected to the connecting pipe 4. The nozzle 9 can pass through the sleeve 3 and the valve body 2 to enter the natural gas pipeline.

[0049] End plate 1 is used to connect to the joint of natural gas transmission pipeline. Rubber parts are installed on end plate 1 to seal the joint of natural gas transmission pipeline and prevent leakage at the joint. Bolt holes are provided on end plate 1, and the end plate 1 is bolted to the flange on the joint of natural gas transmission pipeline through the bolt holes, thereby fixing end plate 1 on the flange. A through hole 8 is opened in the middle of end plate 1 for nozzle 9 to pass through, so that nozzle 9 enters natural gas transmission pipeline.

[0050] The connecting pipe 4 is used to connect the defoamer injection pipeline. A nozzle 9 is installed on the connecting pipe 4 to spray the defoamer into the natural gas transmission pipeline. The connecting pipe 4 is detachably connected to the defoamer injection pipeline, which makes it easy to remove the connecting pipe 4 to clear the nozzle 9 and the defoamer injection pipeline.

[0051] The sleeve 3 is used for detachable connection with the valve body 2, so that the connecting pipe 4 can be easily installed and removed from the valve body 2. The sleeve 3 and the connecting pipe 4 can be relatively displaced. Under pressure, the connecting pipe 4 can be moved to detach from the valve body 2, thereby allowing the valve body 2 to close.

[0052] The seal 10 is used to seal the connection between the connecting pipe 4 and the sleeve 3, so as to prevent oil and gas leakage when the connecting pipe 4 and the sleeve 3 are relatively displaced.

[0053] In one or more embodiments, the sleeve 3 and the connecting pipe 4 are connected by threads. By causing the connecting pipe 4 and the sleeve 3 to rotate relative to each other, the connecting pipe 4 can be displaced along the axial direction of the sleeve 3, so that the end of the connecting pipe 4 with the nozzle 9 can extend into or leave the valve body 2, so that the nozzle 9 can enter or leave the natural gas pipeline, thereby allowing the valve body 2 to open or close.

[0054] In an optional embodiment, the connecting pipe 4 is provided with a first connecting part 6, the external shape of the first connecting part 6 is constructed as a prism, so that the first connecting part 6 can be engaged with the wrench, thereby facilitating the application of force.

[0055] In an optional embodiment, an internal thread is provided at one end of the sleeve 3, and an external thread is provided on the outer wall of the connecting pipe 4. The internal thread at the end of the sleeve 3 is adapted to the external thread on the outer wall of the connecting pipe 4, so that the relative position of the sleeve 3 and the connecting pipe 4 can be changed, which facilitates the adjustment and setting of the sealing element 10.

[0056] In one or more embodiments, the sleeve 3 is threadedly connected to the valve body 2, with an external thread at the end of the sleeve and an internal thread at the valve body 2, thereby making the sleeve 3 and the valve body 2 detachably connected, facilitating installation and disassembly.

[0057] In an optional embodiment, the sleeve 3 is provided with a second connecting part 7, the outer wall of the second connecting part 7 is prismatic, and the second connecting part 7 can be engaged with the wrench for easy application of force.

[0058] In one or more embodiments, the nozzle 9 is detachably connected to the connecting pipe 4, allowing the nozzle 9 to be disassembled for replacement and quickly restoring the working state of the defoamer injection pipeline.

[0059] In one or more embodiments, the seal 10 includes an annular structure through which the connecting pipe 4 passes. The annular structure abuts against the connecting pipe 4 and against the sleeve 3. The annular seal 10 can better seal the connecting pipe 4 and prevent oil and gas leakage.

[0060] In an optional embodiment, the sleeve 3 is provided with a first limiting ring 11 and a second limiting ring 12. The first limiting ring 11 and the second limiting ring 12 are spaced apart to form a limiting groove. The annular structural member is disposed in the limiting groove. The annular structural member abuts against the first limiting ring 11 and the second limiting ring 12. The first limiting ring 11 and the second limiting ring 12 abut against the two sides of the annular structural member to limit the annular structural member in the axial direction of the sleeve 3, so as to prevent leakage caused by the displacement of the annular structural member with the connecting pipe 4. When the connecting pipe 4 and the sleeve 3 are relatively displaced, the connecting pipe 4 and the annular structural member slide relative to each other, ensuring a good sealing effect of the annular structural member. The connecting pipe 4 can pass through the first limiting ring 11 and the second limiting ring 12.

[0061] In one or more embodiments, the connecting pipe 4 is provided with a connecting block 5, which is rotatably connected to the connecting pipe 4. The connecting block 5 is used for detachable connection with the defoamer injection line. The rotatable connection between the connecting block 5 and the connecting pipe 4 makes the connecting pipe 4 easy to rotate, which facilitates the installation and adjustment of the connecting pipe 4.

[0062] Specifically, the valve body 2 is a stainless steel ball valve, and the valve core of the ball valve is provided with a channel that allows the nozzle 9 to pass through.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
