Abstract
The utility model relates to a large caliber pipe joint, which belongs to the technical field of pipe joints. The large caliber pipe joint comprises a joint body 1, a nut 6, a sealing ring 3 arranged in the joint body, a cushion ring 4, and an inner conical C-shaped clamping ring 5. The inner surface on the end part of the joint body is an outer conical structure which is matched with the inner conical C-shaped clamping ring 5. When the large caliber pipe joint is used, a water pipe is inserted into the joint body. When the nut and the joint body are engaged and screwed, the inner conical outer surface of a C-shaped long ring is exactly and mutually matched with the outer conical inner surface on the end part of the joint body, and the water pipe and the joint body are tightly and firmly connected. The utility model is especially suitable for the fixing connection of pipes with large caliber of more than phi 30 mm.
Description
The utility model relates to a kind of large-diameter pipe joint, belongs to the pipe coupling technical field.
Existing pipe joint is mainly the plug bush type structure, promptly on pipe joint, be provided with the engaging body that can insert water pipe, this type of joint mostly can only be used for connecting in the small-bore water pipe below diameter is Φ 30mm, and use is subject to the corrosion of flowing medium in the water pipe and damages for a long time.
The purpose of this utility model provides a kind of reasonable in design, and good airproof performance connects fast simple large-diameter pipe joint.
The utility model is the large-diameter pipe joint, comprise fittings body, place the nut of fittings body end, place the seal ring in the fittings body, packing ring and the c shape collar that is provided with opening is characterized in that described c shape collar is interior tapered structure, the outer tapered structure of fittings body end internal surface for matching with interior tapered c shape collar, the fittings body end is provided with external screw thread, is provided with female thread in the nut.During use, be placed in nut, interior tapered c shape collar, packing ring, seal ring on the pipe successively, water pipe is inserted in the fittings body, when female thread on nut and the engagement of the external screw thread on the fittings body are tightened, the interior tapered outer surface of c type collar is just in time identical mutually with the outer tapered internal surface of fittings body end, and the internal surface of C type collar is close to water pipe, promptly finishes the fixedly connected of pipe.
Also can be provided with plastic lining layer in the described fittings body; The front portion of described plastic lining layer can be step structure, and described seal ring is placed in the ladder of plastic lining layer front portion; The internal surface of tapered c type collar can be laciniation in described.
The utility model compared with prior art has following distinguishing feature and good effect:
1, reasonable in design, the outer tapered structure of interior tapered c type collar and fittings body end internal surface is sealed and matched mutually, make pipe joint close and firm more when being connected with pipe, both had excellent sealing performance, avoided again in the prior art having prevented the torsional deflection of pipe because of existing the gap easily to make pipe loosening between collar and the fittings body.The plastic lining layer that is provided with in the fittings body can avoid medium mobile in the water pipe to contact with the fittings body of metallic material in addition, makes to the utlity model has corrosion resistance preferably.
2, structure is more compact, and the utility model has reduced the engaging body structure of inserting pipe in the fittings body, has both helped the manufacturing of pipe joint, has made things convenient for the connection of heavy caliber pipe again.
3, the utlity model has easy for installation, good airproof performance, corrosion resistance is strong, uses distinguishing features such as reliable, can be widely used in the conveying of tap water and Korrosionsmedium, is particularly useful for the fixedly connected of the above heavy caliber pipe of Φ 30mm.
Accompanying drawing has provided structural representation of the present utility model;
Fig. 1 is an overall structure half sectional view of the present utility model;
Fig. 2 is the decomposition half sectional view of each parts of the utility model.
Below in conjunction with embodiment the utility model is further described:
The utility model is mainly by fittings body 1, place the nut 6 of fittings body end, place the plastic lining layer 2 in the fittings body, seal ring 3, packing ring 4, interior tapered c shape collar 5, lining 7 formations such as grade, the outer tapered structure of fittings body end internal surface for matching with interior tapered c shape collar, the fittings body end is provided with external screw thread 10, be provided with female thread 11 in the nut, the internal surface 9 of c shape collar 5 is a laciniation, and plastic lining layer 2 front portions are step structure.Fittings body is generally metallic material, can select aluminum casting or copper casting for use.
During use, earlier lining 7 is embedded in the water pipe 8, again with nut 6, interior tapered c type collar 5, packing ring 4, seal ring 3 grades are enclosed within outside the water pipe 8 successively, then water pipe is inserted the plastic lining layer 2 in the fittings body 1, turn nut 6, make the moon, sun nut 11,10 engagements, be screwed in the process at nut, seal ring 3 falls in the ladder of plastic lining layer front portion, collar 3 is forced to tighten up under the roof pressure of the compressing of nut 6 and packing ring 4, make its internal surface 9 be close to the outer surface of water pipe 8, and tapered outer surface just in time coincide in it, and water pipe 8 closely is connected with fittings body 6 mutually with the outer tapered internal surface of fittings body 1 end.
