Abstract
A female connector (1; 101; 201) for connecting at least two stiff metal pipes (2) and a piping system obtained with the use of said female connector are described. The female connector is made of cast iron by smelting or casting and is coupled to the ends of metal pipes (2) by means of pressing with automatic pressing pliers.
Description
The present invention relates to a kind of be used to the connect connector of metallic conduit and relevant plumbing connection system.
As is known, in construction industry, pipe-line system is used to carry as fluids such as water, gas.Described pipe-line system comprises a plurality of rigid metal conduits made of iron that are generally, and it interconnects by the screwed female connector of generally cylinder iron making.In order to connect between pipeline and connector, pipe end must be shaped on an outside thread, then connector is screwed on the pipeline, thereby the internal thread of connector and the outside thread of pipeline are meshed together.
There are various defectives in described plumbing connection system according to prior art.
In practice, must use the threaded mold that on pipeline, to make screw thread in the working site.And very big being not easy to of the volume of described threaded mold carried.
When after making screw thread on the pipeline, must twine screw thread with fiber or special teflon and combine with the fastening of connector guaranteeing.This can additionally cause the waste of time and materials.
At last, must finish by higher specialized skills being threaded of each parts, with guarantee to seal fully and with the conformity of overall dimensions.
Owing to the activity duration very long, therefore can have influence on final job costs according to the plumbing connection system needs of prior art.
The objective of the invention is by a kind of operator of being suitable for is provided the actual plumbing connection system that uses and can reduce the activity duration to greatest extent, to overcome defective of the prior art.
Another object of the present invention provides a kind of general, flexibly and be applicable to the plumbing connection system of the pipeline of different shape and size.
A further object of the invention provides the economic and simple plumbing connection system of a kind of making.
Realize these purposes according to the present invention with listed feature in the appended independent claims 1.
Can understand advantageous embodiment of the present invention by dependent claims.
This plumbing connection system utilizes a female connector that at least two rigid metal conduits are interconnected.Described female connector is cylinder iron made through melting or casting or cast, and relies on pressure clamp to be pressed on the end of metal tube.In order to ensure closely, advantageously will be contained within the female connector such as the Stamping Steel Ribbon Tibetan of O shape ring.
Advantage according to female connector of the present invention is conspicuous.In fact, in this connector, can remove screw thread and encircle and guarantee its tightness by O shape.In addition, pressure clamp is a kind of small-sized instrument that is easy to handle.
In this way, make the pipeline attended operation obtain simplifying and having reduced job costs and time.
In order to have the pourability bigger, and obtain to help to make complex-shaped material, preferably use the cast iron of Kohlenstoffgehalt about 2.1% than small castings such as connector than iron.
In addition, to carry out meticulous heat treatment to this cast iron connector, with obtain can with the rigidity and the toughness of iron phase ratio, can be with the purpose of pressure clamp compacting thereby reach.
By following to shown in the accompanying drawing only as example and nonrestrictive embodiment's detailed description can be understood further feature of the present invention more.In the drawings:
Fig. 1 is the perspective exploded view according to first embodiment of plumbing connection system of the present invention, and one comprises a linear connector and two assemblies with connected pipe end shown in it;
Fig. 2 is the axial, cross-sectional view of assembly among the Fig. 1 that assembles;
Fig. 3 is the axial, cross-sectional view of linear connector;
Fig. 4 is a perspective view according to a second embodiment of the present invention, connects the L shaped connector of two pipe ends shown in it;
Fig. 5 is the axial, cross-sectional view of the L shaped connector among Fig. 4;
Fig. 6 is the perspective view of a third embodiment in accordance with the invention, connects the T shape connector of three pipe ends shown in it;
Fig. 7 is the axial, cross-sectional view of the T shape connector among Fig. 6.
Now plumbing connection system according to the present invention is described by means of accompanying drawing.
With reference to Fig. 1-3 first embodiment of the present invention is described.
Fig. 1 illustrates a linear connector that can connect two pipeline 2 ends.Linear connector 1 has one and is the main body 10 of cylindricality substantially, and its inside is empty, the cylindrical axial passage 11 of opening before and after having determined thus.
The internal diameter of linear connector 1 is substantially equal to or is slightly less than the external diameter of pipeline 2, thereby can make the combination between connector 1 and the pipeline 2 have minimum gap.
And shown in Fig. 2 and 3, two pairs of annular seatings 12 that can hold corresponding O shape ring 13 are arranged in the internal surface of connector 1, near two end.O shape ring 13 is made in order to guarantee the excellent sealing on pipeline 2 outer surfaces by rubber.
In addition, at the close center position of the internal surface of connector 1, be provided with an inwardly radially outstanding annular collar 14, it has determined two interfaces.Annular collar 14 is used as the insertion stop of pipeline 2.
The end of connector 1 has two cylindrical end tangs 15, and its external diameter is bigger with respect to the intermediate portion of main body 10.Cylindrical end tangs 15 is used for making the thickness of connector 1 to keep in balance in the zone of the seat 12 that O shape ring 13 is set.
In order to assemble described pipe-line system according to the first embodiment of the present invention, fully the end of two pipelines 2 is inserted the port of connector 1, be close proximity to the axle collar 14 of connector 1 up to the end of two pipelines 2.At this moment, connector 1 is pushed, be pressed on the outer surface of pipeline 2, thereby make it be firmly fixed at pipeline 2 with automatic pressure pincers.O shape ring 13 also is pressed in their seat 12, to guarantee good pneumostop.
Below, will represent and the similar or corresponding parts of described these parts with identical reference symbol, and omit its explanation.
Figure 4 and 5 illustrate connector 101 according to a second embodiment of the present invention.The bending part of the main body 10 of this connector 101 is bent to basic for L shaped, with connect two therebetween angle be 90 ° pipeline 2.Be provided with two annular stop collars 14 in this case, each axle collar places the end of main body 10 curved sections.
Fig. 6 and 7 illustrates the connector 201 of a third embodiment in accordance with the invention, and wherein connector 201 is that three-way connector is to connect three pipelines 2.
The main body 10 of connector 201 is essentially T shape and has three inlets that are suitable for three pipelines 2.Thus, two pipelines connect and the 3rd pipeline is connected between the former two with 90 ° angular distance along a straight line.In this case, provide three annular stop collars 14, be arranged at and prevent to be inserted into the position that the pipe end in the connector 201 interferes with each other.
Clearly, also can provide the connector of other type, for example the cross connector connect four its be partitioned into 90 ° pipeline, perhaps crooked, parabolic shape connector waits and connects the pipeline with complex curve.
Feature of the present invention shows as, and described connector is made by cast iron and is incorporated into metal tube by extruding.Preferably use Kohlenstoffgehalt to be about 2.1% cast iron, to have good cast.Thereby by cast iron being carried out melting and casting or pouring into a mould and make connector.Subsequently with connector in addition heat treatment to obtain favorable rigidity and toughness.
For a person skilled in the art, can carry out various modifications and variations to embodiments of the invention, and not deviate from as determined scope of the present invention in the claims.
