Description
Technical Field
[0001] The utility model relates to the technical field of geological exploration, in particular to a flow guide used in high-pressure rotary jet grouting construction. Background Art
[0002] As an important tool in high-pressure rotary jet grouting construction, the flow guide (commonly known as the faucet) has the functions of inputting medium and diverting medium. Different types of hoses input different media (hardened material liquid (cement slurry), water, compressed air, hydraulic oil, etc.) into the flow guide. Nowadays, with the development of the field of high-pressure rotary jet grouting construction in recent years, the construction method has gradually changed from ordinary rotary jet (i.e. single-tube method, double-tube method, triple-tube method) to RJP method (commonly known as double high-pressure rotary jet method), S-RJP method and MJS method (all-round high-pressure jet method) and super rotary jet method, etc. Correspondingly, the construction pressure that only required 20MPa before needs to be increased to 40MPa at present, and even can reach more than 45MPa under special working conditions. The existing flow guides on the market have at most two channels that can maintain a high pressure of less than 30MPa for a short time, which increases the construction limitations and affects the construction efficiency.
[0003] The corresponding flow guide has also been continuously developed from the earliest single tube to the current eleven-tube flow guide. Currently, most of the three-tube flow guides on the market are set up according to the channels of different media, which are stacked together. This structure of the three-tube flow guide cannot match the construction of eleven-tube drilling tools. Therefore, a multi-channel, large-flow flow guide is needed, and it can match the current RJP, S-RJP, MJS, ultra-high pressure and ultra-large flow processes during construction. In addition, it is also necessary to ensure the channel while avoiding the collision and entanglement of the hoses when the multiple pipelines of the flow guide are constructed at the same time, so as to adapt to the high-pressure rotary spraying process.
[0004] Therefore, the market needs a deflector that can stably withstand high pressure above 45MPa, has multiple pipelines, and has a rotatable medium channel. Utility Model Content
[0005] The classification of deflectors on the existing market is too complicated. Generally, a drill pipe is only suitable for its specific deflector. The poor versatility leads to high production costs. In addition, since the structures of deflectors are different, it is difficult for workers to distinguish and disassemble and repair them. In order to solve the above problems in the prior art, the utility model provides an ultra-high pressure, multi-pipeline, full-rotation deflector.

DETAILED DESCRIPTION
[0017] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0018] An ultra-high pressure, multi-pipe, full-rotation deflector, which can be equipped with different hose joints according to construction requirements. For example, if the drill pipe is a six-ply pipe, the deflector only needs to connect six channels, and the remaining channels can be left unconnected. A maximum of eleven channels can be connected, which is used for the construction of eleven-ply pipe drill pipes.
[0019] It includes a core shaft 1, which has a large diameter and can be suitable for ultra-large flow processes. At the same time, it can reduce the flow rate, effectively reduce the friction resistance and energy loss in the medium pipeline, avoid excessive noise and vibration in the pipeline, and improve the safety of the medium channel operation.
[0020] The surface finish of the core shaft 1 inside the deflector is relatively high, which effectively reduces the energy loss caused by the passage of the internal medium.
[0021] The middle outer side of the mandrel 1 is sleeved with a middle shell 2, the right outer side of the mandrel 1 is sleeved with an upper shell 3, and the left outer side of the mandrel 1 is sleeved with a lower shell 4; the contact between the middle shell 2 and the mandrel 1 is provided with an air joint spacer 5 and a retaining ring 6; the air joint spacer 5 in the deflector has good mechanical strength and processing accuracy, and has multiple uses. It can not only be used as a bearing spacer, but also a medium transmission channel to ensure the smooth passage of the medium.
[0022] A first transition joint 7 and a rotary seal 8 are provided at the contact point between the upper shell 3 and the core shaft 1; the shaft rotary seal 8 provided inside the deflector is made of nitrile rubber / polytetrafluoroethylene-bronze (NBR-PTFE-bronze), which is wear-resistant, high-temperature resistant, can withstand ultra-high pressure and has a guaranteed service life.
[0023] The entire channel of the deflector can achieve 360° rotation, effectively avoiding collision and interference of hoses when multiple pipelines are constructed simultaneously.
[0024] The contact between the lower shell 4 and the core shaft 1 is provided with an ultra-high pressure rotary seal 9 and a fluororubber O-ring 10; the deflector is provided with an ultra-high pressure rotary seal 9 inside, which can withstand ultra-high pressure, up to 50Mpa. The fluororubber O-ring 10 is made of high-quality fluororubber (FKM) material, which has good high temperature resistance and medium resistance, and can still maintain good medium resistance and compression deformation resistance even under high temperature conditions.
[0025] A compression shell 11 is installed on the right side of the upper shell 3, and a shackle ring 12 is installed on the outer side of the compression shell 11; a second transition joint 13 is installed on the left side of the lower shell 4, and a standardized channel connection joint 14 is installed on the outer side of the second transition joint 13. Most of the existing deflector joints on the market are self-made parts, and the long processing cycle leads to high prices. The standardized channel connection joint 14 is a national standard joint (standard part). If damaged, it can be disassembled and replaced immediately, and the deflector shell is not affected, which effectively guarantees the service life of the deflector. In addition, similar channels can be connected through hoses through standard joints to achieve multiple uses.
[0026] The top of the lower shell 4 is penetrated with an input water channel 101, the top of the middle shell 2 is penetrated with an input gas channel 102, the top of the upper shell 3 is penetrated with a first input slurry channel 103, and the top of the pressure shell 11 is penetrated with a second input slurry channel 104. The guide can fix the slurry, gas, water and other hoses connected to the guide, so multiple pipelines can be constructed simultaneously during work.
[0027] The standardized channel connection joint 14 is fixed to the outer side of the second transition joint 13 by three sets of connection screws 201. The standardized channel connection joint 14 is provided with a first channel 301, a second channel 302, a third channel 303, a fourth channel 304, a fifth channel 305 and a sixth channel 306. The channels of the flow guide are not intertwined or leaked, and the interfaces connected with the hose are distributed on different planes, and do not interfere with each other after the hose is connected.
[0028] At present, most of the deflectors in the domestic market have obvious high and low pressure distinctions, which are subject to many restrictions during installation. However, when designing this deflector, all channels can withstand ultra-high pressure, and there is no need to specifically distinguish between high pressure, medium pressure, and low pressure channels. When using it, you only need to pay attention to whether the coordinate position of each channel is consistent with the coordinate position of the drill pipe hole.
[0029] The deflector is suitable for RJP, S-RJP, MJS, ultra-high pressure and ultra-large flow processes, and also meets the ordinary triple-tube process, effectively solving the problem of single construction method.
[0030] The guide device has high matching precision, which can not only meet the general construction requirements, but also provide the possibility for high-end rotary jet grouting construction drilling tools.
[0031] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.
