Abstract

The utility model relates to a pipeline connector, in particular to a fast pipeline connector which comprises a connecting coat with an outer edge. The end with the outer edge is connected with a round ring disk in a dismountable manner and the other end is internally embedded with a pressing connecting coat; a sealed feeding ring is arranged between the pressing connecting coat and the round ring disk; the end of the round ring disk connected with the connecting coat is provided with a ring-shaped boss whose outer diameter is smaller than the inner diameter of the connecting coat. The utility model can effectively improve the labor intensity and has the advantages of convenient operation, no need of large-scale matching device, as well as can high efficiently and rapidly connect and maintain the pipeline, save material and save capital.

Description

The rapid pipeline connector

One, technical field

The utility model relates to a kind of pipe jointer, especially relates to a kind of rapid pipeline connector.

Two, background technique

The Placement of various pipelines in the industrial and agricultural production at present, generally adopt the methods such as butt joint, flange connection and welding that are threaded, beat mouth with cement, the Placement of these several pipelines generally all must be to be operated by the professional and technical personnel, but also need a series of matched auxiliaring equipment, long construction period, labor intensity is big.Especially for the welding manner that is adopted in the construction of oil and natural gas pipeline, its welding procedure complexity requires operator's welding technique height, work under bad environment not only, in case and welding quality do not pass a test, also can leave over down potential safety hazard.

Three, summary of the invention

The purpose of this utility model provide a kind of can improve effectively labor intensity, easy to operate, do not need large-scale corollary equipment, efficiently, rapid pipeline connector quickly.

The utility model is realized in the following way: a kind of rapid pipeline connector, it comprises that an end has the connection overcoat of outer rim, its end that has outer rim is connected by the detachability mode with a circle ring disk, stud with a pressure welding case in its other end, between pressure welding case and circle ring disk, be filled with the stuffing box packing ring, the end that described circle ring disk matches with described connection overcoat has an external diameter less than the annular boss that connects outer casing internal diameter, and described stuffing box packing ring is a nitrile butadiene rubber.

Effect of the present utility model is as follows:

(1) labor intensity is low, easy to operate: the rapid pipeline connector that the utility model provides, just on two pipes that join, load onto joint sleeve, pressure welding case during connecting tube, being coated with upper gland packing etc. gets final product, do not need other complicated and professional operation, thereby labor intensity is low, easy to install.

(2) efficient, quick: the rapid pipeline connector that the utility model provides is easy for installation, simple to operate, does not need supplementary equipment, saves time the efficient height.

(3) safe and reliable, of many uses: the stuffing box packing that the utility model adopts, after two ends are compacted, both can guarantee that sealing was reliable between two pipes, again because the cold and hot scalability of stuffing box packing, can prevent pipeline crack or joint damage, can save ducted slip joint or U type like this and bend that it not only can be used for cast iron tube, steel pipes such as oil, rock gas and also can be used for other materials as during the pipeline of the PVC that water adopted connects up and down owing to expanding with heat and contract with cold.

(4) the maintenance pipeline makes things convenient for, saves trouble: the rapid pipeline connector that the utility model provides also can be used to keep in repair pipeline, when pipeline need cut maintenance, removes bad pipe, change the new pipe of same length, put joint sleeve, crimping gets final product, and makes things convenient for, saves trouble, fast.

(5) save material, economize on the use of funds: the rapid pipeline connector that the utility model provides, used material is few, not electricity consumption, without main equipment, the human and material resources of input are few.

Five, embodiment

As shown in Figure 1, a kind of rapid pipeline connector, it comprises that an end has the connection overcoat 3 of outer rim 8, its end that has outer rim 8 is connected by the detachability mode with a circle ring disk 6, stud with a pressure welding case 2 in its other end, between pressure welding case 2 and circle ring disk 6, be filled with stuffing box packing ring 4, pressure welding case 2 and circle ring disk 6 are to be used for compressing, compacting stuffing box packing ring 4, for the stuffing box packing ring 4 that is fixed and clamped better, the end that described as shown in Figure 2 circle ring disk 6 matches with described connection overcoat 3 can be processed with an external diameter less than the annular boss 7 that connects overcoat 3 internal diameters, annular boss 7 is stretched into connect in the overcoat 3; In order to ensure the reliable sealing of two connected tube connecting parts, and cold and hot stretchability, stuffing box packing ring 4 can adopt nitrile butadiene rubber.

As shown in Figure 3, described outer rim 8 can be processed into flange during use, described circle ring disk 6 also is processed into the flange plate that matches with described outer rim 8, the two connects by bolt 5, connecting the length of overcoat 3 and the outside dimension of connected tube 1 equates, the internal diameter that connects overcoat 3 is that the external diameter of connected tube 1 adds five pipe thicknesses, when connecting two velamen connecting tubes 1, be enclosed within on the pipe connecting overcoat 3, the circle ring disk 6 that has annular boss 7 is enclosed within on another root pipe, annular boss 7 is positioned at a side of pipe connecting part, behind the mouth of pipe of alignment two tubes, cover upper gland packing ring 4 at the tube interface place, in an end of joint sleeve 3 no outer rims 8, be bumped into pressure welding case 2 then, compress, compacting stuffing box packing ring 4, firmly be pressed into the boss on the circle ring disk 67 in the connection overcoat 3 this moment, the flanged surface of the two is loaded onto bolt 5 and just can after closely contacting; When pipeline need cut maintenance, remove bad pipe, change the new pipe of same length, load onto the connector that the utility model provides, this swings to repair to bring to operating pipeline and greatly facilitates and safety.
