Description

Port connection mode of acoustic pipe

Technical Field

The utility model relates to a connection of tubular product, especially a sounding pipe port connected mode.

Background

At present, when the ports of the acoustic pipes are connected, the traditional mode is that the ports of the acoustic pipes to be connected are butted on site, a sleeve is used for covering the interface, and then the two ports of the sleeve are respectively welded with pipe bodies of the acoustic pipes on the two sides; because of the limitation of the conditions of field welding equipment, an electric welding machine is usually adopted for electric welding, and because the current is very large, if the pipe wall is too thin, the sounding pipe is easily burnt through, the pipe body and the sleeve pipe need to have certain thickness, and obviously, the welding method of the sleeve pipe needs to respectively weld the two ends of the sleeve pipe, namely, the two ends are welded twice, so that the labor intensity of workers is high, and the cost is high.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a sounding pipe port connected mode makes the thickness attenuate of sounding pipe, and the scene only needs the welding once. The utility model discloses the technical problem that solve is realized through following technical scheme:

the utility model provides a sounding pipe port connected mode, includes A sounding pipe and the B sounding pipe of mutual butt joint, sets up the A sleeve pipe in the butt joint department of A sounding pipe, and the A sleeve pipe leaves one section butt joint notch, sets up the B sleeve pipe in the butt joint department of B sounding pipe, and the B sounding pipe leaves one section butt joint lug, and butt joint notch and butt joint lug cooperation are connected.

Further, the length of the butt joint notch is the length of the sleeve A extending out of the port of the acoustic measurement pipe A; assuming that the length of the butt notch is L1 and the outer pipe diameter of the sounding pipe is D, L1 is 1.5D.

Furthermore, the length of the butt convex port is the length between the port of the sound measuring tube B and the sleeve tube B; if the length of the butt convex port is L2, L2 is L1-2 mm.

Specifically, the thickness of the sound measuring tube is 3.5 mm-1.0 mm.

Specifically, the thickness of the sleeve was 3.5 mm.

The utility model discloses the thickness attenuate of sounding pipe is made to sounding pipe port connected mode, and the scene only needs the welding once, and welded intensity of labour has reduced half, good reliability, and is with low costs.

fig. 2 is a schematic connection diagram of the present invention.

Detailed Description

Fig. 1 is the utility model discloses a schematic structure diagram, as shown in fig. 1, a sounding pipe port connected mode, including A sounding pipe 1 and B sounding pipe 2 of mutual butt joint, set up A sleeve pipe 3 in A sounding pipe 1's butt joint department, one section butt joint notch 4 is left to A sleeve pipe 3, sets up B sleeve pipe 5 in B sounding pipe 2's butt joint department, and B sounding pipe 2 leaves one section butt joint protruding mouth 6, and butt joint notch 4 and butt joint protruding mouth 6 cooperate to be connected.

The length of the butt joint notch 4 is the length of the sleeve A3 extending out of the port of the sound measuring tube 1A, the length of the butt joint notch 4 is set to be L1, the outer diameter of the sound measuring tube is set to be D, and then L1 is 1.5D; the length of the butt convex port 6 is the length between the port of the B sounding pipe 2 and the B sleeve 5, and the length of the butt convex port 6 is L2, so that L2 is L1-2mm, and in order to ensure that the sleeves on the two sides can be butted after being inserted, the length L1 of the butt notch 4 is slightly greater than the length L2 of the butt convex port 6; the thickness of the sound measuring tube is 3.5 mm-1.0 mm, and the thickness of the sleeve is 3.5 mm.

The utility model discloses during the use, accomplish the welding of sleeve pipe and sounding pipe in the mill in advance, the concrete mode is, overlap A sleeve pipe 3 and B sleeve pipe 5 respectively at the butt joint port department of A sounding pipe 1 and B sounding pipe 2, wherein A sleeve pipe 3 keeps one section butt joint notch 4, a sleeve pipe 3 promptly will stretch out one section length than the port of A sounding pipe 1, and B sounding pipe 2 keeps one section butt joint notch 6, B sleeve pipe 5 promptly will be more than the port of B sounding pipe 2 and retract one section length, the outer pipe diameter of the sounding pipe of this embodiment is 57mm, then L1 equals 1.5 x 57mm equals 85.5mm, get the integer, the length of butt joint notch 4 is 85mm, L2 equals 85-2 equals 83mm, the length of butt joint notch 6 is 83 mm; because welding in the mill, welding equipment can adopt carbon dioxide arc welding, and this kind of welding is also difficult for burning through the pipe wall when the pipe wall thickness reduces, so can greatly reduced to the thickness requirement of sound side pipe, can reduce more than 50%, is 3mm to 3.5mm like traditional sounding pipe thickness promptly, adopts the utility model discloses a connection structure and welding method can make the thickness of sounding pipe reduce to 1.5mm, 1.0mm even.

Fig. 2 is the utility model discloses a connection schematic diagram, as shown in fig. 2, because the prewelding has been carried out in the mill in advance, so only need at the scene to insert butt joint notch 4 with butt joint protruding mouth 6, then weld just to accomplish with the butt joint department of A sleeve pipe 3 and B sleeve pipe 5, because on-the-spot if take the electric welding mode, therefore sheathed tube thickness still should not attenuate, the utility model discloses sheathed tube thickness is 3.5 mm. The welding mode is characterized in that the traditional two-time welding mode of the sleeve pipe-sound measuring pipe on site is changed into the one-time welding mode of the sleeve pipe-sound measuring pipe on site, so that the operation is good, the speed is high, the labor intensity is low, the reliability is better, and the cost is reduced. The utility model discloses except that sounding pipe, the port of other similar tubular products is connected and is also suitable for.

In a word, the utility model discloses the thickness attenuate of sounding pipe is made to sounding pipe port connected mode, and the scene only needs the welding once, and welded intensity of labour has reduced half, good reliability, and is with low costs.
