Description

Technical Field

[0001] This invention relates to the field of pipe fittings, specifically a docking assembly and flange fitting. Background Technology

[0002] Flange fittings are a type of welded pipe fitting. These fittings are used to match pipes. Some are machined, while others are not. Some castings produce the flange as a whole, while welded flanges are machined later. They can be machined in a factory or on-site.

[0003] In the existing technology, the flange pipe is connected between the conveying pipes on both sides by bolts. That is, after the flange pipe is placed between the flanges of the conveying pipes on both sides, the through holes on the surface of the flange pipe are aligned with the through holes on the surface of the flange, and then the bolts are passed through the two sets of through holes and locked to achieve fixation. In this way, a firm connection between the flange pipe and the conveying pipes on both sides is completed.

[0004] However, in traditional flange pipe installation, one worker needs to support the flange pipe while another worker installs the bolts before the bolts are installed. This means that the flange pipe cannot be pre-positioned with the delivery pipe, making it inconvenient for a single person to install the flange pipe. Summary of the Invention

[0005] The purpose of this invention is to provide a docking assembly and flange fitting to solve the problems mentioned in the background art.

[0007] Preferably, the surface of the flange has multiple through holes through which bolts pass. The surface of the through holes has an embedding groove, and a rubber clamp is fixed inside the embedding groove. The width of the rubber clamp is greater than the depth of the embedding groove, and the rubber clamp is held between the bolt and the embedding groove.

There are multiple elastic hanging plates, and the multiple elastic hanging plates are arranged and distributed along the side wall of the first flange. The clamping strip is an arc strip with a right trapezoidal cross section and is fixed on the surface of the elastic hanging plate. After the first flange and the conveying pipe are fixed by bolts, the clamping strip is stuck on one side of the conveying pipe.

[0009] Preferably, the side groove is opened on the surface of the elastic hanging plate. The side groove and the clamping strip are symmetrically distributed with respect to the elastic hanging plate. An arc guide surface is integrally formed at one end of the side groove, and a first pull ring is fixed on the surface of the side groove.

[0010] Preferably, the traction member includes a sleeve ring, a picking groove, a second pull ring, and a wire bundle strip. The sleeve ring is movably sleeved on the pipe body of the connecting pipe fitting. A picking groove is opened on the outer ring surface of the sleeve ring. The picking groove is an annular groove, and multiple second pull rings are fixed on the surface of the picking groove. One end of the traction rope is bolted to the second pull ring, and the other end of the traction rope is bolted to the first pull ring.

[0013] Preferably, the sealing and blocking component includes a cover plate and a rubber gasket ring. The cover plate is in a ring plate structure with a "C" - shaped cross section and is fixed at one end of the sleeve ring. A rubber gasket ring is fixed at one end of the cover plate. There are two rubber gasket rings, and the sizes of the two rubber gasket rings are different, and the two rubber gasket rings are distributed on both sides of the groove body of the cover plate.

[0014] A flange pipe fitting includes the docking component described above.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The docking component and the flange pipe fitting proposed by the present invention add a limit clamping member between the first flange and the second flange to realize the pre - limit when the connecting pipe fitting and the conveying pipe are docked, avoid the dislocation when the connecting pipe fitting and the conveying pipe are spliced, meet the requirement of single - person operation to complete the connection and fixation of the connecting pipe fitting and the conveying pipe, and after adding the traction member, by拨动 the traction member, the limit clamping member can be withdrawn by tensioning the traction rope.
