Description

Technical Field

[0001] This utility model relates to the field of gas pipelines, specifically to an emergency sealing device for gas pipeline leaks. Background Technology

[0002] Gas pipelines mainly consist of gas transmission pipelines and gas distribution pipelines. The gas distribution pipelines primarily connect to users and are characterized by low pressure, numerous branches, dense networks, and small diameters. Except in special locations, gas distribution pipelines are generally constructed using steel pipes.

[0003] In daily life, we often see yellow gas pipelines, mainly on the outside of residential buildings and in basements. These pipelines are often susceptible to damage from external forces, aging, and corrosion, making them prone to minor leaks. Maintenance personnel often find these leaks difficult to address on-site and frequently require emergency sealing devices before reporting to the gas company for repair or replacement. To facilitate timely sealing of gas pipeline leaks by maintenance personnel, this invention provides an emergency sealing device for gas pipeline leaks. Summary of the Invention

[0007] Preferably, the closed ring is circular in shape, the depth of the closed ring is no more than 1 / 4 of the thickness of the closed strip, and the closed ring is filled with organic fireproof sealant, the sealant being 5mm to 8mm higher than the closed strip after filling the closed ring.

[0008] Preferably, the leak sealing patch is rectangular or circular in shape, the depth of the leak sealing patch is the same as the depth of the sealing ring, the leak sealing patch is filled with the same sealing putty as the sealing ring, and the thickness of the sealing putty filled in the leak sealing patch is the same as the thickness of the sealing putty filled in the sealing ring.

[0009] Preferably, the center point of the leak sealing patch coincides with the circle of the sealing ring.

[0010] Preferably, the fastening structure consists of a strap, a buckle, and a retaining pin, wherein the retaining pin and the sealing strap are integral, the buckle is inserted into the retaining pin, and the strap and the buckle are integral.

[0011] Preferably, each of the sealing strip bodies has no less than three sets of fastening structures, wherein the first set of fastening structures is located directly above the leak point sealing patch, two sets of fastening structures are located above the sub-closed loop and are symmetrically distributed along the first set of fastening structures, and the remaining fastening structures are symmetrically distributed to the left and right along the first set of fastening structures.

[0012] Preferably, the inner surface of the sealing strip is coated with self-adhesive, and a release film is pressed on top of the self-adhesive.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The optimized closed-loop structure makes it easy for gas pipeline maintenance personnel to carry and allows it to better fit the gas pipeline to form a seal.

[0015] 2. Apply sealant to combine sealant with sealing tape to form a first-level seal (leak sealing tape) and a second-level seal (sealing ring) around the leak, which strengthens the overall sealing strength.

[0016] 3. The fastening structure is used to tighten the sealing strip, and the fastening structure can pressurize the sealing putty, which increases the sealing strength between the leak sealing tape and the sealing ring.

[0017] 4. The fastening structure and the self-adhesive on the inner surface of the sealing strip form a double-insurance fastening effect, ensuring that this utility model can be fastened to the gas pipeline. Attached Figure Description
