Description

Technical Field

[0001] The utility model relates to the technical field of natural gas station measurement equipment, in particular to a liquid level meter dredging device suitable for a normal pressure formation water tank. Background Art

[0002] Existing natural gas production and transportation stations generally have buffer tanks that have been in use for a long time after construction or that contain a lot of solid impurities in the air flow from external wells. After separation and discharge, a lot of impurities enter the buffer tank and settle at the bottom of the tank, causing the channel connecting the liquid level meter to the bottom of the tank to gradually become blocked, causing the liquid level meter to be distorted. The liquid level meter may not follow the rise of the liquid level after production or the drop of the liquid level after transportation, affecting the production measurement of formation water and the measurement of oil and water transportation. Even for those well stations with huge water production, the distortion of the liquid level meter display is very likely to evolve into an environmental incident.

[0003] Clearly, resolving the problem of formation water tank level gauge blockage and ensuring accurate formation water metering are crucial for safe production at natural gas production and transmission stations. Previously, clearing formation water tank level gauge blockage required draining the tank and then disassembling the level gauge. This was a complex, time-consuming, and labor-intensive process, with low efficiency.

[0004] Although there are other methods for unclogging liquid level gauges in the prior art, they are mainly aimed at blockages caused by low-temperature crystallization. For example, the Chinese utility model patent with publication number CN204269182U involves a device for solving the blockage of the lower pipe of the liquid level gauge. It uses gas heating to solve the problem of blockage caused by medium solidification in the lower pipe of the liquid level gauge. Obviously, it is not suitable for the blockage of the formation water tank level gauge described above.

[0005] Therefore, it is necessary to study a liquid level gauge dredging device suitable for normal pressure formation water tanks to solve the above problems or alleviate the impact of the above problems. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, the liquid level gauge dredging device of the present invention may include a dredging device 10 and a main body in a three-way structure; wherein,

[0031] The main body includes a main pipe 1 and a branch pipe 2 connected to the middle of the main pipe 1. The first end of the main pipe 1 is used to connect to the control ball valve of the liquid level gauge (not shown in the drawings). The second end of the main pipe 1 is provided with a dredging hole 3 for installing a dredge 10. The third end of the branch pipe 2 is used to connect to a recovery container (not shown in the drawings).

[0032] The dredge 10 can be inserted into the dredge hole 3, and its dredge end sequentially passes through the main pipe 1 and the opened control ball valve to the blockage at the bottom of the liquid level gauge, and can perform dredging operations through vibration stirring.

[0033] Specifically, the main pipe 1 is installed at the bottom of the level gauge to provide an operating channel for the dredge 10 to perform dredging operations, so that the dredge 10 can pass through the main pipe 1 and extend into the bottom of the level gauge to dredge the blockage. The first end of the main pipe 1 is connected to the control ball valve of the level gauge. When the control ball valve of the level gauge is opened, the main pipe 1 is connected to the bottom of the level gauge; the second end of the main pipe 1 is provided with a dredging hole 3, which matches the dredge 10 and can form a seal on the second end of the main pipe 1 when the dredge 10 is inserted into the dredging hole 3, so that the dredging operation can be performed without emptying the formation water tank; and the main pipe 1 is coaxial with the pipe connecting the bottom of the level gauge and the formation water tank, so that the dredging end of the dredge 10 can pass through the main pipe 1 and the opened control ball valve in sequence to the blockage at the bottom of the level gauge, thereby performing the dredging operation.

[0034] One end of the branch pipe 2 is connected to the middle of the main pipe 1, and the other end is connected to the recovery container. In this way, when the dredge 10 dredges the blockage at the bottom of the liquid level gauge, the liquid in the formation water tank and the blockage can be discharged into the recovery container together to avoid the blockage remaining in the formation water tank.

[0035] The dredging end of the dredge 10 can extend to the blockage at the bottom of the liquid level meter, and the blockage is loosened by vibration stirring. Then, the blockage is discharged to the recovery container through the branch pipe 2 together with the liquid under the pressure of the liquid in the formation water tank.

[0036] Overall, the liquid level gauge dredging device of the present invention is connected to the control ball valve of the liquid level gauge through a main body, and then installed in conjunction with the dredging device 10. This device can dredge blockages at the bottom of the liquid level gauge through vibration and agitation. Furthermore, because the dredging device 10 is installed through the dredging hole 3, dredging can be performed without draining the formation water tank. The liquid level gauge dredging device has a simple structure and is easy to operate. It can improve the accuracy of formation water tank measurement and prevent environmental incidents.

[0037] Furthermore, the central axis of the dredging hole 3 is consistent with the central axis of the main pipe 1 .

[0038] In one example, Figure 1 As shown, a first flange 4 is fixedly provided at the end of the first end of the main pipe 1 , and the first flange 4 is used for flange connection with a control ball valve of a liquid level gauge.

[0039] Specifically, the first end of the main pipe 1 can be fixedly connected to the first flange 4 by welding, and the first flange 4 is fixedly connected to the flange on the control ball valve at the bottom of the liquid level gauge by bolts, thereby realizing the connection between the main pipe 1 and the control ball valve at the bottom of the liquid level gauge.

[0040] In one example, a rubber sheet 5 is fixed to the end of the second end of the main pipe 1 , and a dredging hole 3 is opened in the center of the rubber sheet 5 .

[0041] Specifically, the rubber sheet 5 covers the second end of the main pipe 1, with a dredging hole 3 at its center, matching the size of the dredge 10. When the dredge 10 is inserted into the dredging hole 3, it forms a seal against the second end of the main pipe 1, preventing the liquid in the formation water tank from escaping from the second end of the main pipe 1 after the level gauge is dredged. The rubber sheet 5 is made of rubber and has a certain degree of elasticity, which ensures a good seal with the dredge 10. The rubber sheet 5 also has good oil and corrosion resistance, which extends the service life of the device.

[0042] In one example, Figure 1 As shown, the rubber sheet 5 is fixed to the second end of the main pipe 1 by clamping the second flange 6 and the third flange 7. Of course, this is only a preferred way to fix the rubber sheet 5, and other ways can also be used to fix the rubber sheet 5.

[0043] Furthermore, the second flange 6 is fixedly connected to the end of the second end of the main pipe 1 , and the second flange 6 and the third flange 7 are connected by bolts and clamp the rubber sheet 5 therebetween.

[0044] Specifically, the second flange 6 is fixedly connected to the end of the second end of the main pipe 1 by welding, and the second flange 6 and the third flange 7 are connected by bolts. The rubber sheet 5 is clamped between the second flange 6 and the third flange 7. It should be noted that the rubber sheet 5 has a certain elasticity, and the size of the dredging hole 3 on the rubber sheet 5 can be adjusted by the degree of clamping between the second flange 6 and the third flange 7, thereby further ensuring the sealing between the dredge 10 and the rubber sheet 5.

[0045] In one example, the thickness of the rubber sheet 5 is 8-12 mm, such as 8 mm, 10 mm or 12 mm.

[0046] In one example, the dredge 10 is a metal wire or a metal rod, and the outer diameter of the dredge 10 matches the inner diameter of the dredge hole 3 , so that the rubber sheet 5 cooperates with the dredge 10 to seal the second end of the main pipe 1 .

[0047] Specifically, the dredge 10 can be made of iron wire, copper wire, thin iron rod, or thin copper rod. The dredge 10 is required to have a certain degree of rigidity so that it can vibrate and agitate to loosen the blockage and achieve dredging. The outer diameter of the dredge 10 is the same as the inner diameter of the dredge hole 3, so that when the dredge 10 is inserted into the dredge hole 3, the rubber sheet 5 and the dredge 10 tightly fit together to form a seal against the second end of the main pipe 1.

[0048] Furthermore, the inner diameter of the dredging hole 3 may be 3 to 8 mm, for example, 3 mm, 3.2 mm, 5 mm or 8 mm.

[0049] In one example, Figure 3 As shown, a vibrator 11 is provided at the other end of the dredge 10 relative to the dredging end, so that the dredge 10 has a vibration stirring function, which can dredge the blockage at the bottom of the liquid level meter. The vibrator 11 provides the driving force for the dredge end of the dredge 10 to vibrate and stir.

[0050] In one example, Figure 1 and Figure 2 As shown, the third end of branch pipe 2 is connected to drain valve 8 via nipple 9. Drain valve 8 is used to control the connection between branch pipe 2 and the recovery container. When clearing the blockage at the bottom of the level gauge, drain valve 8 is opened to drain the blockage along with the liquid through branch pipe 2 into the recovery container.

[0051] Furthermore, the drain valve 8 may be a ball valve.

[0052] In one example, the main body has a T-shaped three-way structure, with the axis of branch pipe 2 perpendicular to the axis of main pipe 1. Specifically, main pipe 1 is arranged horizontally, while branch pipe 2 is arranged vertically. This allows blockages at the bottom of the level gauge to be unblocked, allowing the blockage to be drained smoothly along with the liquid through branch pipe 2 into a recovery container. Furthermore, the main pipe 1 and branch pipe 2 have the same radial dimensions.

[0053] In order to better understand the above embodiment, the working process of the liquid level gauge dredging device of the present invention will be further described below with reference to the accompanying drawings.

[0054] First, assemble the main body of the level gauge dredging device and connect the first flange 4 of the main pipe 1 to the flange of the control ball valve at the bottom of the level gauge. Next, insert the dredging end of the dredging tool 10 through the dredging hole 3 in the rubber sheet 5 and into the obstruction at the bottom of the level gauge. Connect the other end of the dredging tool 10 to the vibrator 11. The vibration and agitation of the dredging tool 10 will gradually loosen and disintegrate the obstruction. Then, entrained by the liquid in the formation water tank, the obstruction will flow along the main pipe 1 and branch pipe 2 and through the drain valve 8 into the recovery container. The level gauge will then display the normal liquid level in the formation water tank.

[0055] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
