Abstract

The utility model discloses a coal gas pipeline connection system. The system comprises an elbow pipe body, a three-way pipe body, and a plug. The upper end of the elbow pipe body is connected with a connection pipe through threads. The lower left pipe orifice of the elbow pipe body is connected with lower right pipe orifice of the three-way pipe body through threads, and a first sealing nut which is sleeved onto the lower left pipe orifice of the elbow pipe body is connected with the lower right pipe orifice of the three-way pipe body through threads. The plug is connected with the lower right pipe orifice of the three-way pipe body through threads. The upper end of the three-way pipe body is connected with a second sealing nut through threads. According to the utility model, impurities in a pipeline can be cleaned at the plug position, advantages, such as fast and efficient operation, convenience, simplicity, good sealing performance, etc., are achieved, and the phenomenon of air leakage at joints of a coal gas pipeline is effectively avoided, so the quality of coal gas pipeline installation works is ensured.

Description

Connect the gaspipe line system
Technical field:
The utility model relates to a kind of pipeline connecting part, particularly relates to a kind ofly being connected the gaspipe line system by what bend part and threeway parts were formed.
Background technique:
Coal gas is a kind of clear energy sources, and easy to use, and the own piped gas that is widely used in the vast cities and towns of China is done civilian and industrial fuel.The elbow of the pipeline connecting parts that gaspipe line installing engineering is at present used and threeway are to adopt the single-stage seal arrangement, and sealing effect is bad, and leakage gas causes potential safety hazard easily, can not guarantee the quality of coal gas installing engineering.In addition, the area of contact on link such as existing gaspipe line elbow and threeway and ground is little, when certain external pressure, will move by occurrence positions, makes elbow be prone to produce distortion and gas leakage.
Summary of the invention:
The utility model provides a kind of double sealing structure that has for solving the problem that above-mentioned existing technology exists, and is difficult for producing the connection gaspipe line system that move the position.
Connect the gaspipe line system; Comprise bend part, threeway parts and adapter, bend part comprises elbow body, seal ring and interlocking nut, and the outer side wall of elbow body upper pipes mouth is provided with an annular boss; The interlocking nut sleeve is contained on the elbow body; The annular door of the lower end of interlocking nut and annular boss clamping have internal thread on the upper end inwall of interlocking nut, and seal ring is nested with on the outer side wall of elbow body upper pipes mouth; The upper-end surface of its lower end surface and annular boss closely cooperates, and the adapter of interlocking nut and pipeline is through being threaded.On the outer side wall of left side, the elbow body lower end mouth of pipe first outside thread is arranged.The threeway parts comprise threeway body, the first trapezoidal seal ring, the second trapezoidal seal ring, first sealing nut, second sealing nut, first seal ring gasket, second seal ring gasket and plug; On three mouth of pipe inwalls of threeway body internal thread is arranged respectively; The peripheral outer side wall of plug. seven have first outside thread, and plug is connected with left side, the threeway body lower end mouth of pipe through screw thread.The interior internal thread of first outside thread on the mouth of pipe outer side wall of elbow body lower end left side and right side, the threeway body lower end mouth of pipe is to be threaded.The inwall of the upper end mouth of pipe of threeway body and right side, the lower end mouth of pipe has outward-dipping flare groove respectively; The first trapezoidal seal ring and the second trapezoidal seal ring embed respectively in the flare groove, on the outer side wall of the upper end of the threeway body mouth of pipe and right side, the lower end mouth of pipe, second outside thread are arranged respectively.First sealing nut and the second sealing nut inwall rear portion have the first seal ring gasket chamber and the second seal ring gasket chamber respectively; First seal ring gasket and second seal ring gasket embed the first seal ring gasket chamber respectively and second seal ring gasket indoor, first sealing nut is connected with right side, lower end mouth of pipe outer side wall with the upper end mouth of pipe of threeway body through screw thread respectively with second sealing nut.
The main advantage of the utility model is to be equiped with the first trapezoidal seal ring and the second trapezoidal seal ring respectively at the groove place of the threeway body upper pipes mouth and right side, the lower end mouth of pipe respectively; This first trapezoidal seal ring and the second trapezoidal seal ring respectively with first sealing nut and second sealing nut in first seal ring gasket and second seal ring gasket be fixed; The seal ring of elbow body suit is taken over fastening and sealing through interlocking nut and pipeline, thereby reaches the twin-stage sealing of gaspipe line parts.In addition, can clear up the impurity in the pipeline through the plug place, so, the utlity model has swift to operate, convenient, simple, good airproof performance, avoided the gaspipe line joint to be prone to the phenomenon of leaking gas effectively, guaranteed the quality of gaspipe line installing engineering.
Description of drawings:
Fig. 1 is a kind of example structure sectional view of the utility model.
Embodiment:
Connect the gaspipe line system, comprise bend part, threeway parts and adapter, bend part comprises elbow body 1, seal ring 2 and interlocking nut 3; The outer side wall of the elbow body 1 upper end mouth of pipe is provided with an annular boss 4; Interlocking nut 3 is sleeved on the elbow body 1, and the annular door 5 and annular boss 4 clampings of the lower end of interlocking nut 3 have internal thread 6 on the upper end inwall of interlocking nut 3; Seal ring 2 is nested with on the outer side wall of the elbow body 1 upper end mouth of pipe; Seal ring 2 lower end surfaces closely cooperate with the upper-end surface of annular 1 when platform 4, and interlocking nut 3 is connected with adapter 7 with screw thread, on the outer side wall of left side, the elbow body 1 lower end mouth of pipe first outside thread 8 are arranged.The threeway parts comprise the trapezoidal seal ring of the trapezoidal seal ring of threeway body 9, first 10, second 11, first sealing nut 12, second sealing nut 13, first seal ring gasket 14, second seal ring gasket 15 and plug 16; On three mouth of pipe inwalls of threeway body 9 internal thread 17 is arranged respectively; On the peripheral outer side wall of plug 16 outside thread 18 is arranged, and plug 16 is connected with left side, threeway body 9 one lower ends mouth of pipe internal thread 17 through screw thread.The interior internal thread 17 of first outside thread 8 on the mouth of pipe outer side wall of elbow body 1 lower end left side and right side, the threeway body 9 one lower end mouth of pipe is to be threaded.The inwall of the upper end mouth of pipe of threeway body 9 and right side, the lower end mouth of pipe has outward-dipping flare groove 19 respectively; Two trapezoidal seal rings 10,11 embed respectively in the flare groove 19, on the outer side wall of the upper end of threeway body 9 mouth of pipe and right side, the lower end mouth of pipe, second outside thread 20 are arranged respectively.First sealing nut 12 and second sealing nut, 13 inwall rear portions have the first seal ring gasket chamber 21 and the second seal ring gasket chamber 22 respectively; First seal ring gasket 14 and second seal ring gasket 15 embed respectively in the first seal ring gasket chamber 21 and the second seal ring gasket chamber 22, and first sealing nut 12 is connected with right side, lower end mouth of pipe outer side wall with the upper end mouth of pipe of threeway body 9 through screw thread respectively with second sealing nut 13.
