Abstract
The utility model relates to a quick joint for pipelines, which can be used as the connection of the pipelines of heating, water delivery, petrochemical industries, etc. The both ends of a main body element are connected with outer nuts. A connected joint is inserted into a concave hole on the end part of the main body element, and a sealing washer is arranged between the both. The conical surfaces of the inner holes of the outer nuts partly press a snap ring in the groove of the joint. The utility model has the advantages of convenient installation and maintenance, and steady connecting effect.
Description
The utility model relates to a kind of pipe coupler.
In the prior art, the heating pipe in industry, family property, chemical industry, field such as civilian and the connecting process of conveyance conduit are more loaded down with trivial details, particularly site operation is installed more difficult, generally by adapted lead oil such as pipe collar, elbow, threeway, the numb thread seal of silk, installation and maintenance labor intensity are big, the on-the-spot installation needs to be equipped with more instrument, installs to be difficult for ensuring the quality of products, and leakage problem often occurs.The bending destructible screw thread that expands with heat and contract with cold of pipeline causes maintenance difficult.
The purpose of this utility model provides a kind of installation and maintenance pipeline speed fitting easily.
The purpose of this utility model is to realize by following measure, the main component 1 two ends scyewed joint outer nut 2 of this fast fitting, there is the shrinkage pool that cooperates with pipe fitting 5 at the two ends of tube-shaped main body spare 1, seal washer 3 is arranged in the shrinkage pool, there is internal thread the endoporus front portion of outer nut 2, its endoporus rear portion is the conical surface, in the annular groove of pipe fitting 5 ends snap ring 4 is arranged, and many ribs faceted pebble section is arranged on the outer surface of outer nut 2.
Snap ring 4 can adopt opening shape steel wire ring.
One end of outer nut 2 outer surfaces is for ease of the faceted pebble section of dismounting, faceted pebble Duan Weiliu faceted pebble.Faceted pebble also can be two ribs or four ribs or eight prismatics.
The convex surface of the external thread section at main component 1 two ends for ease of installing.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
With reference to accompanying drawing is an embodiment of the present utility model, and its structure as mentioned above.
The processing pipe fitting 5 of this example is the heating pipe, connects fast fitting between the two pipe fittings 5.During connection, with the axle head processing annular groove of pipe fitting 5, the cone angle of annular groove is 90 °, pipe fitting 5 puts outer nut 2 earlier, the end shrinkage pool of main component 1 is put in the end of pipe fitting 5, seal washer 3 is arranged between the two, snap ring 4 is put into the annular groove of pipe fitting 5, tighten outer nut 2, make snap ring 4 pressurizeds, pipe fitting 5 is subjected to the pulling force of fast fitting.Unscrew during maintenance and get final product.
These speed fitting installation and maintenance are convenient, are not prone to leakage.
