Abstract

The utility model relates to a water connector for deep drilling, which comprises a water feeding elbow, an upper shell, a suspension connector, an intermediate coupling body and a lower shell. The water feeding elbow and the upper shell are welded as a whole, the upper part of the upper shell is in thread connection with the suspension connector, and the lower part of the upper shell is in thread connection with the lower shell through the intermediate coupling body. The water connector is characterized in that the intermediate coupling body is connected with a core tube in a sealing way through a V-shaped sealing ring group, and the lower shell is connected with a core shaft in a sealing way through a felt-ring oil seal. The utility model has the advantages of: 1) flexible high-speed rotation and capability of bearing the axial tensile force; 2) reliable sealing with the V-shaped sealing ring group capable of bearing high pressure and suitable for delivery of washing liquid and cooling liquid of large pump volume for deep exploration; 3) capability of preventing leakage when the V-shaped sealing ring is worn; 4) small size, simple structure and low replacement cost; 5) suitability for drilling of large-diameter deep holes; 6) convenient disassembly and use and easy maintenance; and 7) suitability for drilling of ordinary single-tube and double-tube drilling and diamond core drilling.

Description

A kind of deep probing water swivel

Technical field

The utility model relates to a kind of geology deep probing water swivel.

Background technology

Water swivel is mounted in geology rock-core borer kelly upper end, is used to connect rubber tube and kelly.The flushing cooling fluid that slush pump is sent by rubber tube, and then is finally delivered on the drill bit of foot of hole through water swivel, drilling rod.The used water swivel ubiquity in driller ground following several shortcoming at present: 1, single action is poor, rotates dumb; 2, core pipe rapid wear; 3, slurries leak; 4, bearing is not durable; 5, the water flowing area is little, resistance is big.Above-mentioned several shortcoming has determined to be not suitable for deep well drilling.

Summary of the invention

Problem to be solved in the utility model is at above-mentioned present situation, uses water swivel and propose the probing of a kind of deep, and superficial part creeps in also being applicable to certainly.It is simple in structure, and cost of production is low, improves the application life of water swivel greatly.

The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: a kind of deep probing water swivel, include into water bend pipe, upper shell, suspension joint, middle connected body and lower house, bend pipe and the upper shell weldering of wherein intaking is one, the upper shell top suspension joint that is threaded, the upper shell bottom is by the middle connected body lower house that is threaded, connected body is by the V-shaped seal ring group core pipe that is tightly connected in the middle of it is characterized in that, lower house is connected with stem seal by the felt collar oil sealing.

Press such scheme, described mandrel is connected by left hand thread with the core pipe, and mandrel is connected by two dish deep groove ball bearings with lower house, also is provided with a thrust ball bearing with flat seat between the two dish deep groove ball bearings.

Press such scheme, described V-shaped seal ring group top also is connected with a spring, in order to regulate V-shaped seal ring group sealing radial pressure.

Press such scheme, described water inlet bend pipe becomes left-handed 20 degree with the axis of upper shell.

The beneficial effects of the utility model are:

1) mandrel is to be connected with two dish deep groove ball bearings, a dish thrust ball bearing with flat seat with housing, and high speed rotating is flexible, can carry axial tension; 2) sealing is reliable, and the sealing of V-shaped seal ring group can be born higher pressure, and cooling fluid is washed in the conveying that is suitable for the big pump amount of deep prospecting; 3) spring can be regulated the pressure of V-shaped seal ring group automatically, prevents the leakage of liquid under the situation of V-shaped seal ring wearing and tearing; 4) housing maintains static, and rotatable parts are divided into core pipe and mandrel, and consumable accessory is the core pipe, and volume is little, and is simple in structure, and replacement cost is low; 5) through-hole diameter is big, and energy loss was little when liquid flow through, and is fit to creep into the heavy caliber deep hole; 6) dismounting and easy to use is easy to safeguard; 7) be applicable to that common single, double pipe bit advances, diamond wire line coring drilling process.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the syndeton schematic diagram of suspension joint, water inlet bend pipe and upper shell.

The specific embodiment

Below in conjunction with in conjunction with the accompanying drawings the utility model being done further detailed description.

Shown in Fig. 1-2, water swivel is used in the probing of the utility model deep, includes suspension joint 1, upper shell 2, water inlet bend pipe 3, spring 4, core pipe 5, pressure-bearing packing ring 6, middle connected body 7, V-shaped seal ring group 8, deep groove ball bearing 9, thrust ball bearing with flat seat 10, packing ring 11, lower house 12, deep groove ball bearing 13, felt collar oil sealing 14, mandrel 15.

All component can be divided into fixed part, middle transition parts, rotary part by the motion state in when work.Fixed part is: suspension joint 1, upper shell 2, water inlet bend pipe 3, middle connected body 7, lower house 12.Middle transition parts: spring 4, pressure-bearing packing ring 6, V-shaped seal ring group 8, deep groove ball bearing 9, thrust ball bearing with flat seat 10, packing ring 11, deep groove ball bearing 13, felt collar oil sealing 14.Rotary part: core pipe 5, mandrel 15.

Suspension joint 1 and upper shell 2 are threaded by the T type; Upper shell 2 and water inlet bend pipe 3 are integrally welded, and water inlet bend pipe 3 becomes the angles of left-handed 20 degree to weld with the axis of upper shell 2, and its effect is when water swivel turns round, and prevents that into the long-term bending of water rubber tube influences its life-span; Connecting housing 2 on the middle connected body 7, connect lower house 12 down, all is to connect with left hand thread; The liquid that not leakage center is flow through for the kelly that allows core pipe 5 and mandrel 15 be connected along with the lower end rotates at a high speed, core pipe 5 is connected with mandrel 15 usefulness left hand threads, be tightly connected with one group of V-shaped seal ring group 8 and middle connected body 7 on core pipe 5 external diameters, one end connects pressure-bearing packing ring 6, and spring 4 adjusting pressure by being arranged on V-shaped seal ring group top, purpose is to prevent V-shaped seal ring group and core pipe 5 long-time wearing and tearing back leak of liquid, for mandrel 15 can steadily be turned round flexibly along with the kelly of lower end, and make the mandrel 15 can be at the certain pulling force of axial carrying, therefore deep groove ball bearing 9 and deep groove ball bearing 13 have been designed in two ends up and down at mandrel, axially be provided with thrust ball bearing with flat seat 10 in the middle part at mandrel, mandrel 15 is connected by two dish deep groove ball bearings with lower house 12, on mandrel 15, also be provided with a thrust ball bearing with flat seat 10 between the two dish deep groove ball bearings, packing ring 11 is between thrust ball bearing with flat seat 10 and deep groove ball bearing 13, in order to power on the transmitter shaft, felt collar oil sealing 14 is positioned at the lower house lower end, be used for sealing mandrel 15 and lower house 12, mandrel of the present utility model 15 lower ends are threaded with anti-silk with kelly.

Operating principle of the present utility model mainly be suspension joint 1 by wire rope hanging on the overhead traveling crane hook, the water inlet bend pipe is connected with rubber tube, there is the flushing cooling fluid of certain solid phase composition to flow into the utility model from slush pump, flow out from mandrel, enter kelly, enter drilling rod by kelly again, have the flushing cooling fluid of certain pressure to enter at last on the subdrilling head of hole.The housing parts of this device does not rotate, and core pipe and mandrel are done rotation at a high speed, by the screw thread of mandrel bottom, also can promote the drilling rod of constant weight, and in use liquid can not leak.
