一种带有密封装置的水压致裂管
摘要：
本发明涉及一种带有密封装置的水压致裂管，属岩土工程技术领域。该装置由水压致裂管、锁紧螺母、压筒、压板、橡胶密封圈、定位螺母构成；水压致裂管中段设有水压致裂段，在水压致裂管的表面上设置有螺纹，水压致裂段两端由里向外分别依次设置有定位螺母、橡胶密封圈、压板、压筒、锁紧螺母，定位螺母和锁紧螺母分别旋装在水压致裂管上，橡胶密封圈、压板、压筒分别活动套装在水压致裂管上。定位螺母能够调节水压致裂段的长度，橡胶密封圈能够达到密封效果，而且不会产生应力集中，压板和压筒易于锁紧螺母将水压致裂管在试样中的锁紧，本发明的带有密封装置的水压致裂管设计合理，易于加工，易于操作，节省时间，同时能够重复运用，节约资源。
摘要（英）：

The invention relates to a hydraulic fracturing pipe with a sealing device, belonging to the technical field of geotechnical engineering. The device is composed of a hydraulic fracturing pipe body, a lock nut, a pressure cylinder, a pressing plate, a rubber seal ring and a locating nut; the middle section of the hydraulic fracturing pipe body is provided with a hydraulic fracturing section, and the surface of the hydraulic fracturing pipe body is provided with threads; the two ends of the hydraulic fracturing section are orderly provided with the locating nut, the rubber seal ring, the pressing plate, the pressure cylinder and the lock nut respectively from inside to outside; the locating nut and the lock nut are respectively rotatably arranged on the hydraulic fracturing pipe body; the rubber seal ring, the pressing plate and the pressure cylinder respectively movably sleeve the hydraulic fracturing pipe body. The locating nut can adjust the length of the hydraulic fracturing section, the rubber seal ring can achieve the sealing effect. and no stress concentration will be generated; besides, the lock nut can easily lock the hydraulic fracturing pipe body in a sample by the pressing plate and the pressure cylinder. The hydraulic fracturing pipe with the sealing device disclosed by the invention has the advantages of rational design, easy processing and operation, and is capable of saving time and resources and capable of being repeatedly used.
