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 6, a nut 1 which is arranged on the end part of the joint body, a sealing ring 5 which is arranged in the joint body, a gasket 4, an outer conical clamping ring 3, and an inner conical locking sleeve 2 which is matched with the outer conical clamping ring. 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 outer conical clamping ring is pressed by the inner conical locking sleeve, the outer conical clamping ring is appressed with the water pipe, and the water pipe and the joint body are close connected. The large caliber pipe joint has more compact structure and good sealing performance. The large caliber pipe joint is especially suitable for the fixing connection of a pipe 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 external conical shape collar, it is characterized in that also comprising placing in the fittings body and the supporting inner conical lock sleeve of external conical shape collar that the fittings body end is provided with external screw thread, is provided with female thread in the nut.During use, be placed in nut, inner conical lock sleeve, external conical 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, lock sleeve compressing collar, make it to be close to water pipe, promptly finish the fixedly connected of pipe.
Also can be provided with lining in the described fittings body, lining can embed pipe when mounted; Described collar can be provided with opening, and the inner face of collar is a laciniation; Also plastic lining layer can be set in the described fittings body.
The utility model compared with prior art has following distinguishing feature and good effect:
1, reasonable in design, the matching design of inner conical lock sleeve and external conical shape collar, make pipe joint when pipe is fastenedly connected, neither influence its excellent sealing performance, pipe easily rotates with collar when nut rotates synchronously when having avoided original single collar to be provided with again, has prevented the torsional deflection of pipe;
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 places the nut 1 of fittings body end mainly by fittings body 6, places the plastic lining layer 7 in the fittings body, seal ring 5, packing ring 4, external conical shape collar 3, inner conical lock sleeve 2, lining 8 formations such as grade, inner conical lock sleeve 2 places between external conical shape collar 3 and the nut 1, and the fittings body end is provided with external screw thread 10, is provided with female thread 11 in the nut, collar 3 is provided with opening 12 and makes it to be elastic collar, and its inner face 13 is a laciniation.During use, earlier lining 8 is embedded in the water pipe 9, again nut 1, lock sleeve 2, collar 3, packing ring 4, seal ring 5 etc. are enclosed within outside the water pipe 9 successively, then water pipe is inserted the plastic lining layer 7 in the fittings body 6, turn nut 1, make 11,10 engagements of yin, yang screw thread, be screwed in the process at nut, lock sleeve 2 compressing collars 3, collar 3 is forced to tighten up under the roof pressure of the compressing of lock sleeve 2 and packing ring 4, make it to be close to water pipe 9 outer surfaces, treat that nut 1 and fittings body 6 mesh when fastening fully, collar 2 also makes water pipe 9 closely be connected with fittings body 6.
