Description

Technical Field

[0001] This utility model relates to the field of sealing tools, and in particular to an emergency sealing device for sulfur-containing pipeline rupture. Background Technology

[0002] During the production process of sulfur-containing gas wells, the produced wastewater contains high concentrations of sulfides and chlorides, which are extremely corrosive to wastewater pipelines. Sulfides react with steel to form corrosion products that adhere to the inner wall of the pipeline. These products form corrosion cells with the steel substrate, continuously causing electrochemical corrosion. Simultaneously, chlorides have strong penetrating power, capable of penetrating the protective layer on the pipeline surface, further exacerbating corrosion. In actual operation, corrosion damage to wastewater pipelines typically occurs at the bottom of horizontal sections, mainly manifesting as pitting corrosion. This pitting corrosion concentrates in localized areas of the metal surface and gradually penetrates deeper, forming holes or pits. Once a pipeline leaks, the sulfides in the wastewater escape into the surrounding environment, posing a threat to human safety and causing the leaked wastewater to flow onto the ground, polluting the surrounding soil and groundwater resources, resulting in serious environmental problems.

[0003] In existing technologies, when a leak is discovered, workers typically use traditional mechanical sealing methods for emergency response. However, these traditional methods are cumbersome to operate and time-consuming, making it difficult to meet the needs of rapid response. Utility Model Content

[0004] The purpose of this invention is to provide an emergency sealing device for sulfur-containing pipeline rupture, addressing the problem that existing technologies cannot quickly treat corroded pipelines, resulting in prolonged pipeline leakage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An emergency sealing device for sulfur-containing pipeline rupture includes a first clamping part and a second clamping part, wherein the first clamping part and the second clamping part are detachably connected by a locking member;

[0007] A clamping cavity is provided between the first clamping part and the second clamping part. The clamping cavity is used to clamp the pipe to be blocked. A flexible sealing element is provided on the inner wall of the clamping cavity.

[0008] This utility model is an emergency sealing device for sulfur-containing pipeline rupture. It consists of a first clamping part and a second clamping part forming a clamping cavity through which the pipeline can be placed. The first clamping part and the second clamping part can be detachably connected by a locking element, which facilitates the operator to quickly seal the leaking pipeline section. A flexible sealing device is set in the first clamping part. When the operator applies force to seal the pipeline, the flexible sealing device deforms itself to fit more closely to the leak point of the pipeline, thereby improving the sealing performance and safety.

[0009] As a preferred embodiment of the present invention, the first clamping part includes a first arched plate, and first wing plates are symmetrically arranged on both sides of the first arched plate. Each first wing plate is provided with at least one first waist-shaped hole, and the first waist-shaped hole is detachably connected to the locking member.

[0010] The applied force can be more evenly distributed by the first arched plate and the symmetrically arranged first wing plates, reducing local stress concentration and improving the service life of the structure.

[0011] As a preferred embodiment of the present invention, the first arched plate includes a first convex surface, which is the side of the first arched plate away from the clamping cavity. The first arched plate also includes a first concave surface, which is the side of the first arched plate close to the clamping cavity.

[0012] The design of the first concave surface close to the clamping cavity helps to fit the object being clamped more closely, providing a larger contact area, thereby improving the stability and firmness of the clamping.

[0013] As a preferred embodiment of this utility model, the flexible sealing member is connected to the first concave surface.

[0014] As a preferred embodiment of the present invention, the second clamping part includes a second arched plate, and second wing plates are symmetrically arranged on both sides of the second arched plate. Each second wing plate is provided with at least one second waist-shaped hole, and the second waist-shaped hole is detachably connected to the first waist-shaped hole through the locking member.

[0015] The second arched plate and the symmetrically arranged second wing plates can distribute the applied force more evenly, reduce local stress concentration, and improve the service life of the structure.

[0016] As a preferred embodiment of the present invention, the second arched plate includes a second convex surface, which is the side of the second arched plate away from the clamping cavity. The second arched plate also includes a second concave surface, which is the side of the second arched plate close to the clamping cavity.

[0017] The design of the second concave surface close to the clamping cavity helps to fit the object being clamped more closely, providing a larger contact area, thereby improving the stability and firmness of the clamping.

[0018] As a preferred embodiment of this utility model, the locking member includes a locking screw, one end of which is detachably connected to the first oblong hole and the other end of which is detachably connected to the second oblong hole, and the locking screw slides along the length direction of the first oblong hole and the second oblong hole.

[0019] By setting the locking bolts to slide within the oblong hole, if the pipe still cannot be clamped due to the locking bolts after the operator adjusts the distance between the first clamping part and the second clamping part, the position of the locking bolts within the oblong hole (i.e., adjusting the distance between the two locking bolts) can be adjusted to fit and clamp the pipe.

[0020] As a preferred embodiment of this utility model, both ends of the locking screw are provided with locking nuts, which are used to prevent the first clamping part from falling off from the second clamping part.

[0021] By tightening the lock nut, the operator can connect or disconnect the device from the pipeline.

[0022] As a preferred embodiment of this utility model, the flexible sealing component body has a corrosion-resistant structure.

[0023] Since this device is used in pipelines of sulfur-containing gas wells, by setting the flexible plugging component with a corrosion-resistant structure, the service life of the plugging component can be effectively improved.

[0024] As a preferred embodiment of this utility model, both the first clamping part and the second clamping part are steel structures.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0026] 1. This utility model is an emergency sealing device for sulfur-containing pipeline rupture. It consists of a first clamping part and a second clamping part forming a clamping cavity through which the pipeline can be placed. The first clamping part and the second clamping part can be detachably connected by a locking element, which facilitates the operator to quickly seal the leaking pipeline section. A flexible sealing device is set in the first clamping part. When the operator applies force to seal the pipeline, the deformation of the flexible sealing device itself makes it fit more closely to the leak point of the pipeline, thereby improving the sealing performance and safety.

[0027] 2. This utility model is an emergency sealing device for sulfur-containing pipeline damage. By setting the locking bolt to be able to slide in the waist-shaped hole, if the pipeline still cannot be clamped due to the locking bolt after the operator adjusts the distance between the first clamping part and the second clamping part, the position of the locking bolt in the waist-shaped hole (i.e., adjusting the distance between the two locking bolts) can be adjusted to fit and clamp the pipeline.

[0041] Example 1

[0042] like Figure 1-2 An emergency sealing device for sulfur-containing pipeline rupture is shown, comprising a first clamping part 1 and a second clamping part 2, which are symmetrically arranged and detachably connected to form a clamping cavity 4 after connection. The clamping cavity 4 is used to clamp the pipeline. A flexible sealing element 5 is provided on the side of the first clamping part 1 facing the clamping cavity 4. When the operator finds that the pipeline is damaged and needs emergency repair, the side of the first clamping part 1 with the flexible sealing element 5 is attached to the pipeline rupture, and then the first clamping part 1 and the second clamping part 2 are connected and fixed.

[0043] Furthermore, the first clamping part 1 includes a first arched plate 11, with first wing plates 12 symmetrically arranged on both sides of the first arched plate 11. The second clamping part 2 includes a second arched plate 21, with second wing plates 22 symmetrically arranged on both sides of the second arched plate 21. Each second wing plate 22 is connected to the corresponding first wing plate 11 by a locking member 3.

[0044] In one or more embodiments, the first wing plate 12 is provided with at least one first waist-shaped hole 121, and the second wing plate 22 is provided with at least one second waist-shaped hole 221. The first waist-shaped hole 121 and the second waist-shaped hole 221 on the same side wing plate are both connected to the same locking member 3.

[0045] Furthermore, the locking component 3 includes a locking screw 31, one end of which is detachably connected to the first oblong hole 121 and the other end of which is detachably connected to the second oblong hole 221.

The first arched plate 11 also includes a first concave surface 112, which is the side of the first arched plate 11 close to the clamping cavity 4. The design of the first concave surface 112 being close to the clamping cavity 4 helps to fit the clamped object more closely, providing a larger contact area, thereby improving the stability and firmness of clamping.
