Description

A kind of pipe coupling

Technical field

The utility model relates to a kind of pipe coupling, concretely, relates to a kind of pipe coupling that is used for engineering construction or gas, liquid transmission.

Background technique

In general engineering construction, often need to lay gas, liquid pipeline, need to connect between gas, the liquid pipeline, present known connecting means mainly contains three kinds, a kind of for being threaded, the pipe ends that connect at two needs are provided with internal and external threads respectively, then screw thread are connected; A kind ofly is that flange connects, respectively puts a flange, by electric welding flange is welded on the pipeline then, and then flange is coupled together by screw rod etc. at two pipe ends that need to connect; The third connects for indent, promptly carries out indent a connecting tube end, by fastening piece another pipeline is fastened on the connecting tube then.The shortcoming of these three kinds of connecting means is obvious: one needs additional processing screw thread or indent to connect, for the construction project that needs the multitube road, machining screw or indent itself are exactly a huge engineering, if use flange to connect, welding a plurality of flanges also is a large-engineering of wasting time and energy; Two, though when pipeline connects, can fill up in the engineering practice and establish packing ring, seal rings etc. are in order to sealing, but still there is very big problem in whole sealing effect, especially high pressure pipe line, often occur because gas panting etc., such as outdoor cast iron spheroidal graphite pipeline, cause pipe shifted to occur leaking, therefore at present when engineering construction, all be, pipeline junction is wrapped in the concrete pier at pipeline junction concreting pier, though this has solved the seal for pipe joints problem to a certain extent, but think about it that pipeline is connected with a plurality of joints, and at each joint a concrete pier is set all, such engineering expends greatly, and, need to carry out gas or liquid pressure sealing experiment after pipe laying is good, if seepage occurs in certain pipe coupling place, also need concrete pier is knocked out, concreting pier once more after reconnecting, test once more, so itself is just loaded down with trivial details, the expense that wastes time and energy material.

The model utility content

The purpose of this utility model provides a kind of novel pipe coupling, need screw thread be set on pipeline, add flange, but by two-way link pipeline be connected, join strength height, good airproof performance.

In order to reach above-mentioned technique effect, the utility model provides following technical proposals:

A kind of pipe coupling, first pipeline is provided with the two-way link of at least one pair, also correspondence is provided with the two-way link of the described every pair of two-way link and comprises first link and second link on second pipeline, described first link radially is connected around pipeline with second link, be equipped with the side direction chimb on the two-way link of described every pair, on first pipeline on the side direction chimb of two-way link and second pipeline side direction chimb of two-way link be connected along pipeline axial.

Further, the radius of the class circular arc covering of the fan that the cross section of described side direction chimb forms increases vertically gradually, thereby it is little to form an end, the chimb that an end is big.

Further, described side direction chimb is a plurality of boss that are provided with attachment hole.

Further, the side direction chimb is the long strip boss, and the two-way link of described every pair is provided with two side direction chimbs.

Effect of the present utility model is: because two-way link has the connecting base of both direction, one along pipeline radially, one along pipeline axial, the connection of radial direction can make link being fixed on the pipeline tightly, and the connection of two-way link axial direction can make between two pipelines linking together tightly.Because two-way link is the accessory that pairing is used, and does not need pipeline is made any processing, in use, directly can use, thereby avoid machining screw or weld, saved time, material, manpower.For common straight tube, the connection tension strength of two-way link itself just can guarantee the sealing of pipeline.Sliding for only needing the circle zero diopter inside and outside the connecting tube mouth of pipe, do not need to do special processing.

Embodiment

Now in conjunction with specific embodiments the utility model is described further:

Embodiment 1: shown in Fig. 1 to 4 and Figure 10,11, be the structure and the connection diagram of first link, first link, 10 two ends respectively are provided with a connecting base 12 radially, radially connecting base 12 is provided with attachment hole 13, first link 10 is provided with one or two chimb 11 (as shown in Figure 1 and Figure 2), chimb 11 is provided with a plurality of attachment holes 13, because two-way link 1 all matches, every pair first link 10 all is identical with second link 15.

As shown in figure 10, two-way link connection diagram when connecting for the straight tube pipeline, first pipeline 21 is provided with a two-way link 1, also correspondence is provided with two-way link 1 on second pipeline 22, two-way link 1 comprises first link 10 and second link 15, first link 10 and second link 15 radially are connected by connecting base 12 radially around first pipeline 21, equally, also be provided with two-way link 1 on second pipeline 22, the side direction chimb 11 of two-way link 1 axially is connected by screw rod 4 along pipeline on the side direction chimb 11 that is equipped with two-way link 1 on side direction chimb 11, the first pipelines 21 that are provided with attachment hole 13 on the two-way link 1 and second pipeline 22.For enhanced leaktightness, can between first pipeline 21 and second pipeline 22, be provided with SEALING FITTING 3, screw rod 4 can make first pipeline 21 and second pipeline, 22 crush seal joints 3 when tightening up like this.

Two-way link connection diagram when Figure 11 connects for the bend pipe pipeline, as seen from the figure, when bend pipe 23 is connected with straight tube 22 still roughly the same with straight tube between be connected, as long as pipeline has a bit of straight tube, just can use two-way link 1 to connect.Therefore, can use, and effect is fine for this patents such as three-way pipes.

Embodiment 2: as shown in Figure 5, the chimb 11 among the embodiment 1 also can replace with boss 14, and it connects effect also is the same.Be provided with like this, can economical with materials.

Embodiment 3: shown in Fig. 6 to 9, first link 10 and second link 15 on first pipeline 21 are symmetrical arranged, and radially connect by screw rod 4; First link 10 and second link 15 on second pipeline 22 also are symmetrical arranged, but it is slightly different with the link on first pipeline 21, the radius of the class circular arc covering of the fan that the cross section of the side direction chimb 11 of first pipeline, 21 upper connectors forms increases vertically gradually, from plan view Fig. 8, first pipeline, 21 upper connectors, one end is little, and to the other end transition increase gradually; Though and the link on second pipeline 22 also is that an end is little, and increase to the other end transition, but be provided with one in the other end port and connect platform 17, and the cross section radius that connects platform 17 is less than the maximum cross section radius of first pipeline, 21 upper connectors, like this, screw rod 4 can be screwed in the screw 16 on the link on first pipeline 21 by connecting attachment hole on the platform 17.

As shown in figure 12, pipeline connects and can connect by screw rod 4 then and realize by fin 5 is set on

pipeline

22,23, and the setting of even now also is a kind of alternative because transport comparatively existing problems such as difficulty after having set fin.
