Description

Technical Field

[0001] The utility model relates to a gas well pressure guiding pipe settling device, in particular to a variable pressure guiding pipe settling device. Background Art

[0002] The gas well pressure pipe is an external transmission pipe section on the gathering and transportation pipeline used to connect the metering mechanism, sensor mechanism, etc. In order to avoid the influence of the liquid production and sand carrying conditions in the mining process on the metering and monitoring results, and to avoid the pressure pipe being blocked by liquid and buried by sand, a settling device is set on the existing pressure pipe to remove the liquid and sand in the pipeline. Chinese utility model patent CN217459351 U discloses a pressure pipe settling device, which is provided with an air inlet and an air outlet on both sides of the cylinder, a flow blocker is provided in the cylinder, and a sewage outlet is provided at the bottom. The flow blocker is located between the air inlet and the air outlet, so that the natural gas collides with the flow blocker during the process of flowing through the cylinder, and the large particles of liquid and sand therein fall into the cylinder, thereby reducing the content of liquid and sand in the natural gas and reducing the probability of liquid blockage and sand burial on the pressure pipe.

[0003] However, the flow-blocking parts in the existing pressure-guiding pipe sedimentation device constantly collide with liquid, gas and gravel. As the production process proceeds, the flow-blocking parts are prone to wear, resulting in a weakened flow-blocking effect. The service life is short and needs to be replaced regularly. The replaced flow-blocking parts are scrapped, which causes material waste and increases maintenance costs.

[0004] Therefore, there is an urgent need for a technical solution to solve the technical problems that the guide parts of the existing pressure-guiding pipe sedimentation device have a short service life, regular replacement leads to material waste, and increases maintenance costs. Utility Model Content

[0008] The utility model discloses a variable pressure guiding pipe sedimentation device, which is rotatably connected with a sedimentation container, and has a plurality of blocking surfaces on the flow blocking component. When a blocking surface on the flow blocking component is worn, the flow blocking component can be rotated to allow another blocking surface to continue to play a flow blocking effect, thereby extending the overall service life of the flow blocking component, reducing material waste caused by replacement, and reducing maintenance costs.

[0031] A variable pressure-guiding pipe sedimentation device according to the present embodiment has an air inlet 11 and an air outlet relatively arranged on the sedimentation container 1, a sewage outlet is arranged at the bottom of the sedimentation container 1, and the baffle 2 is located between the air inlet 11 and the air outlet. When the natural gas flows through the sedimentation container 1, it collides with the blocking surface 24 on the baffle 2, and the large particles of liquid and gravel therein fall into the sedimentation container 1 and are finally discharged from the sewage outlet. More than two blocking surfaces 24 are arranged on the baffle 2. When the blocking effect of one of the blocking surfaces 24 is weakened due to the impact and wear of gas, liquid and sand, the baffle 2 is rotated relative to the sedimentation container 1 and the other blocking surface 24 is adjusted to be opposite to the air inlet 11, so that the baffle 2 can continue to have a good blocking effect after one of the blocking surfaces 24 is worn, thereby extending the overall service life of the baffle 2, reducing material waste caused by replacement, and reducing maintenance costs.

[0032] In this embodiment, the baffle 2 preferably includes an operating part 21, a connecting part 22 and a flow limiting part 23 which are arranged in sequence. The operating part 21 is the part of the baffle 2 extending out of the sedimentation container 1. The operating part 21 can be a cylindrical structure or a plate-like structure, so that the baffle 2 can be rotated by clamping the operating part 21 by hand or a tool; the connecting part 22 is the part that is connected to the sedimentation container 1, and the connecting part 22 can be a cylindrical structure. The outer surface of the connecting part 22 can be a smooth surface or a thread, so that the connecting part 22 can be rotated with the sedimentation container 1; the flow limiting part 23 can be a plate-like structure or a columnar structure. A plurality of blocking surfaces 24 are formed or arranged on the flow limiting part 23, so that the baffle effect can be adjusted by adjusting different blocking surfaces 24 relative to the air inlet 11.

[0033] In this embodiment, it is preferred that the plurality of flow limiting portions 23 are plate-shaped structural members, and two blocking surfaces 24 arranged in opposite directions are formed on the flow limiting portions 23 .

[0034] In this embodiment, the operating part 21 is preferably crimped to the sedimentation container 1, and a seal 3 is embedded between the operating part 21 and the sedimentation container 1. The seal 3 may be an annular rubber gasket or an annular sealing ring 7, so that the contact gap between the operating part 21 and the sedimentation container 1 is sealed by the seal 3 to prevent gas and liquid leakage in the sedimentation container 1.

[0035] In some embodiments, the operating portion 21, the connecting portion 22 and the flow limiting portion 23 are preferably an integrally formed structural component.

[0036] In other embodiments, it is preferred that a detachable connection structure is provided between the flow limiting portion 23 and the connecting portion 22, so that when all the blocking surfaces 24 on the flow limiting portion 23 are worn, only the flow limiting portion 23 needs to be replaced when the flow blocking element 2 is replaced, which can further reduce the material waste caused by the replacement of the flow blocking element 2 and reduce the maintenance cost.

[0037] In this embodiment, the blocking surface 24 preferably includes one or more of a plane, an inner concave arc surface, and an outer convex elliptical surface. That is, a single flow blocker 2 can be provided with one type of blocking surface 24, or multiple types of blocking surfaces 24; the blocking surface 24 bears the impact and collision of natural gas. When the blocking surface 24 is set as a plane, the airflow can vertically impact the blocking surface 24, and the large particles of liquid and sand therein can fall to the sewage outlet along the blocking surface 24; when the blocking surface 24 is set as an inner concave arc surface, after the airflow impacts the blocking surface 24, the large particles of liquid and gravel therein are not easy to bypass the edge of the blocking surface 24, which can further improve the flow blocking effect.

The cover cap 4 applies an extrusion force toward the sedimentation container 1 to the flow-blocking member 2, so that the connection between the flow-blocking member 2 and the sedimentation container 1 is stable, and the state in which the flow-limiting portion 23 is extended into the sedimentation container 1 can be maintained, thereby preventing the flow-blocking member 2 from jumping up and down under the impact of gas and liquid.

[0041] In this embodiment, a connecting ring 6 is preferably provided on the top surface of the sedimentation container 1. The connecting ring 6 is an annular structural component. The connecting ring 6 is arranged around the baffle 2. An external thread is provided on the outer wall of the connecting ring 6. The cap 4 is provided with an internal thread.

After the cap 4 is connected to the connecting ring 6 in place, the brim structure of the cap 4 can abut against the top surface of the sedimentation container 1, and the inner top surface of the cap 4 can abut against the top surface of the baffle 2. A sealing ring 7 is embedded between the brim structure of the cap 4 and the top surface of the sedimentation container 1, and a buffer pad 5 is embedded between the inner top surface of the cap 4 and the top surface of the baffle 2, so that the baffle 2 is pressed relative to the sedimentation container 1 through the cap 4 to prevent the baffle 2 from shaking or moving during use.

[0043] It can be understood that the sealing ring 7 and the buffer pad 5 can both be rubber structural parts.

[0044] It can be understood that the structures of the connecting ring 6 and the cover cap 4 can be adjusted according to actual conditions, so that the cover cap 4 can be limited and fixed by the connecting ring 6 and the cover cap 4 can be pressed onto the top surface of the baffle 2.

The spring 9 makes the cooperation between the limit rod 8 and the groove 12 more stable, and can effectively prevent the flow blocking member 2 from rotating due to impact during use.

[0049] It can be understood that the limiting portion 25 can be a local structural member protruding from the operating portion 21, or it can be an annular structural member surrounding the operating portion 21. The limiting portion 25 can be an integrally formed structural member with the operating portion 21, or it can be detachably connected, so that the limiting hole 26 and the limiting rod 8 can be set through the limiting portion 25 to play a limiting role.
