Abstract

A pipe coupler comprises a male part and a female part. The male part and the female part comprise receiving areas used for pipes. The male part can be introduced into the female part partially through a free end of the male part. The pipe coupler also comprises a coupling system formed by a lug and a conjugated shell and a waterproof sealing element at the connecting joint of the male part and the female part. The free end, which is to be introduced into the female part, of the male part has an external diameter less than the internal diameter of the receiving area of the male part, so that a gap is left between the male part and the female part and the mutual shift of the male part and the female part is allowed.

Description

Pipe coupling

Technical field

The present invention relates to a kind of pipe coupling.

More particularly, the present invention relates to a kind of quick-release pipe coupling.Such coupling or joint are used in the water supply equipment for agricultural or industrial use especially.

Background technique

Spain patent documentation ES2172441 discloses a kind of quick-release coupling for plastic tube, this coupling is made by plastics common unit and the auxiliary assembly of molded same inner diameter, and by comprising bump and coordinating the system of housing that common unit is incorporated in auxiliary assembly and by these two parts and is mutually coupled.Liner between two parts is guaranteed water tightness.At the free end of described parts, therefore corresponding plastic tube is introduced into and in the housing that has groove that forms, and object is that pipe is fixed in described common unit and auxiliary assembly.Finally, hydraulic diameter (being internal diameter) between two sections of pipe couple region in neither can increase also and can not reduce.

But such joint has the defect of the variation that can not adapt to the soil gradient.Another problem (Guan Eryan to horizontal positioned especially) of such joint is internal liquid (being generally water) inconvenience discharge, and it is complicated that pipe is emptied completely, need device to receive to be contained in all water in multiple pipeline sections of pipe, otherwise will produce excessive ponding.

Summary of the invention

The object of the present invention is to provide a kind of type of coupling or the joint without above-mentioned shortcoming, thereby allow the use of this coupling or joint not to be subject to the impact of the soil gradient, and allow in the draining of difference place.

Another object of the present invention is open a kind of coupling device, those pipes that this device can be used in two metal tubes or is made up of other materials (especially plastics).

Therefore, coupling device involved in the present invention is general, fast, conveniently and dismountable.

More particularly, the present invention includes a kind of pipe coupling, this pipe coupling has common unit and auxiliary assembly, described common unit and described auxiliary assembly have the receiving area for pipe, and common unit can partly be introduced in auxiliary assembly by the free end of common unit, this pipe coupling also has the coupling system being made up of bump and cooperation housing and has the Sealing for the water tightness at common unit and auxiliary assembly coupled position place, wherein, the free end that is intended to be incorporated in auxiliary assembly of common unit has the external diameter that is less than the internal diameter of auxiliary assembly in described receiving area, thereby leave clearance space between common unit and auxiliary assembly, to allow the mutual skew of described common unit and described auxiliary assembly.

Preferably, the liner of watertight is lips formula liner.More preferably, liner is arranged in the housing of auxiliary assembly.

Being especially preferably in the design of metal tube, particularly (but being not limited to) aluminum pipe, is to be positioned at entrance on the inner side of parts can carry out the welding of pipe for the inlet region of pipe.

More preferably, the system of bump and housing comprises protruding bump, from parts one stretches out this bump, and can be introduced in the cooperation housing in another parts, this housing can be by approaching window and utilizing two motions in succession and approached, one in two motions for moving axially, and another is for moving radially.

In the present invention, common unit and and auxiliary assembly between clearance space existence allow adapt to ground, make one in pipe can be with respect to another definite number of degrees that tilt.For this reason, the design of coupling must not have other elements of the function that stops described gap completely.The joint that is formed with bump and housing system not only allows the relative movement of pipe, and has guaranteed that pipe keeps being coupled in together after described motion.

Another characteristic of the present invention is that especially, in the time using lip formula liner (particularly lips formula liner), the water tightness of coupling improves by the increase of the interior pressure of Guan Zhongshui.Therefore, in the time that equipment is drained, coupling loses water tightness, and water discharges in uniform mode by the joint between the section of area under control, has reached desirable effect compared with at present available technology.

Embodiment

Fig. 1 for example shows two sections of couplings that (3 and 4) form by aluminum pipe, and one section in these two sections connects common unit 2, and another section connects auxiliary assembly 1.

Common unit 2 is furnished with the inlet region 21 for managing 3, and auxiliary assembly 1 has the inlet region 12 for managing 4.Shown in example in, described inlet region comprises the entrance separately on the inner side that is positioned at two parts.The in the situation that of aluminum pipe, pipe 3 and 4 is positioned at housing 21 and 12, by weld seam 32 and 41 welding, and with corresponding shoulder 22 and 11 adjacency of described entrance.

As seen from the figure, common unit 2 remains and is partly incorporated in auxiliary assembly 1.

Coupling is furnished with the connected system consisting of bump (lug) 5 and cooperation (conjugated) housing 61.The feature of common unit 2 is bumps 5, and this bump radially stretches out from common unit, and the feature of auxiliary assembly is housing section 6, and this housing section is provided with housing 61, and this housing radially stretches out and coordinates with described bump 5 from auxiliary assembly 1.For arriving housing 61, bump must and complete two motions in succession through window 62, and first in these two motions is in succession depicted as radially according to arrow E, and second is depicted as axial (see figure 5) according to arrow D.

As found out, common unit 2 is less than the internal diameter of auxiliary assembly 1 at the external diameter of its introducing portion, once so that common unit 2 has been introduced in auxiliary assembly 1, can maintains gap h(between the outer surface of common unit 2 and the internal surface of auxiliary assembly 1 and see Fig. 7).As found out by Fig. 9 and Figure 10, the coupling illustrating does not comprise other elements that can hinder or stop the relative movement of two parts in the h of gap completely, thereby allow the journal offset of two parts, and thereby allow to be attached to the skew of the described common unit 2 of coupling and the pipe of auxiliary assembly 13 and 4.

Coupling also has liner 7, is lips formula in this example.Described liner is filled the clearance space h between common unit 2 and auxiliary assembly 1, and is arranged in the cylindrical entrance of housing 17 or auxiliary assembly 1.The lip of lips formula liner is positioned to towards pipe 4 sidepieces that connect with auxiliary assembly 1.

Fig. 2 to Fig. 6 shows the installation process that couples joint schematically.The connection of common unit 2 and corresponding pipe 3 is according to shown in arrow A and radial rotary, so being introduced in the movement process in auxiliary assembly 1 according to the common unit 2 shown in arrow B, can not produce interference between bump 5 and housing section 6.Then, common unit 2 is rotated counterclockwise by the direction shown in arrow E with the assembling of pipe 3, once and by this radial motion process of arrow E, bump 5 is introduced into by window 62, by execution shown in arrow D, bump 5 is incorporated into the extraction campaign in housing 61, and therefore guarantees that joint is locked in the position shown in Fig. 7 and Fig. 8.

Owing to having clearance space h between common unit 2 and auxiliary assembly 1, and suppose this space neither can be obstructed also not by any way mechanical blockage and form with interlock system and interfere, so therefore, two parts self can be offset, make can have angle α between the axis of the pipe connecting with common unit and auxiliary assembly respectively, as seen at Fig. 9 and Figure 10.Conventionally can reach 7o by the available angle of example.In Fig. 9 and Figure 10, although can observing between pipe 3 and pipe 4, we there is skew, the liner lip 7 arranging is how to keep Leakage prevention.
