Abstract
A kind of air delivering pipeline connection threeway, comprise threeway, described threeway is known available threeway, it is characterized in that: the first interface place extension of threeway has the first lengthening interface, first to lengthen interface and first interface be one-time formed overall structure, and the first lengthening internal thread of interface mates with the internal thread of first interface and is connected.Second jointing extension of threeway has the second lengthening interface, and second to lengthen interface and the second interface be one-time formed overall structure, and the internal thread of the second interface mates with the internal thread of the second interface and is connected.3rd jointing extension of threeway has the 3rd to lengthen interface, and the 3rd to lengthen interface with the 3rd interface be one-time formed overall structure, and the internal thread of the 3rd lengthening interface mates with the internal thread of the 3rd interface and is connected.Screw thread can all cover by the utility model, outside protection joint screw thread is not exposed to, improves corrosion resistance and working life, and improves the usage safety performance of fuel gas pipeline.
Description
Technical field
The utility model relates to a kind of air delivering pipeline connected element, particularly relates to a kind of air delivering pipeline connection threeway, good seal performance, and screw thread connects place and not easily ruptures, long service life.
Background technique
Gasification construction and development is one of important measures improving the gentle quality of urban human people's livelihood running water.Fuel gas transmission be unable to do without pipe-line system.And the connection of pipeline be unable to do without link, as threeway, elbow, valve etc.The threeway wherein used at present, the internal thread segment of three connection mouths is short, the outside thread of the galvanized pipe being attached thereto end is caused to expose, very easily be corroded, cause trommel, mechanical strength weakens, and screwed connection place is easily ruptured, and the working life reducing galvanized pipe easily occurs gas leakage accident simultaneously.
Model utility content
The purpose of this utility model provides a kind of air delivering pipeline connection threeway for existing threeway above shortcomings.The utility model can be protected outside joint screw thread is not exposed to, and provides corrosion resistance and working life, and improves the usage safety performance of fuel gas pipeline.
The technological scheme adopted is:
A kind of air delivering pipeline connection threeway, comprise threeway, described threeway is known available threeway, it is characterized in that:
The first interface place extension of threeway has the first lengthening interface, and first to lengthen interface and first interface be one-time formed overall structure, and the first lengthening internal thread of interface mates with the internal thread of first interface and is connected.
Second jointing extension of threeway has the second lengthening interface, and second to lengthen interface and the second interface be one-time formed overall structure, and the internal thread of the second interface mates with the internal thread of the second interface and is connected.
3rd jointing extension of threeway has the 3rd to lengthen interface, and the 3rd to lengthen interface with the 3rd interface be one-time formed overall structure, and the internal thread of the 3rd lengthening interface mates with the internal thread of the 3rd interface and is connected.
Advantage of the present utility model:
The utility model has the lengthening interface of integration respectively by three jointings, and the galvanized pipe place screw thread that energy available protecting connects is sudden and violent not outside, improves corrosion resistance, improves working life.In addition, improve the Safety performance of pipeline, three-way interface is originally short, and the thread section that the galvanized pipe of connection exposes causes trommel because being very easily corroded, and mechanical property weakens, and sealing effect is poor, easily occurs gas leakage, causes the accident.The utility model good seal performance, Safety performance is high, and easy for installation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
A kind of air delivering pipeline connection threeway, comprises threeway 1, it is characterized in that:
It is one-time formed overall structure that the first interface 2 place extension of threeway 1 has the first lengthening interface 3, first to lengthen interface 3 with first interface 2, and the internal thread of the first lengthening interface 3 mates with the internal thread of first interface 2 and connects into overall screw thread; It is one-time formed overall structure that second interface 4 extension of threeway 1 has the second lengthening interface 5, second to lengthen interface 5 with the second interface, and the internal thread of the second lengthening interface 5 mates with the internal thread of the second interface 4 and connects into overall screw thread; 3rd interface 6 place extension of threeway 1 has the 3rd to lengthen interface, and the 3rd to lengthen interface with the 3rd interface be one-time formed overall structure, and the internal thread of the 3rd lengthening interface 7 mates with the internal thread of the 3rd interface 6 and connects into overall screw thread.For accompanying drawing one, wherein: D
1be 23mm, L for 41mm, α be 46mm, D be 45mm, δ are 3.5mm, L
1for 11mm.
