Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the geological exploration faucet assembly of the present embodiment includes a core pipe 2, one end of the core pipe 2 is connected to a slurry inlet joint 1, and the other end is connected to a slurry outlet joint 14 through a housing 11;
the mud inlet joint 1, the core pipe 2 and the mud outlet joint 14 form a channel for transporting mud inside.
The shell 11 is rotatably connected with the core tube 2 through a bearing piece 9, and a first sealing ring 13 is arranged on the contact surface of the inner wall of the shell 11 and the outer wall of the core tube 2.
In one embodiment, a plurality of first seal rings 13 are provided at intervals in the axial direction along the contact surface between the inner wall of the housing 11 and the outer wall of the core tube 2, and as shown in fig. 1, a hydraulic pressure O-ring rubber seal is used for each of the three first seal rings 13.
The three first sealing rings 13 can effectively prevent mud from entering the bearing piece 9 to cause bearing damage.
Specifically, the outer wall of the circumference of the core tube 2 is provided with a mounting groove for mounting the first sealing ring 13.
The core tube 2 is sleeved with a gland 7, and the gland 7 is in threaded connection with the shell 11 and used for axially positioning the bearing piece 9.
Specifically, the outer side of the circumference of the shell 11 is lathed with external threads which are matched with the internal threads of the inner wall of the gland 7.
One end of the bearing piece 9, which is far away from the gland 7, is provided with a retainer ring 10, and the retainer ring 10 is installed in an installation groove on the core tube 2 and used for axially positioning the bearing piece 9.
Specifically, the gland 7 and the retainer ring 10 axially restrain the bearing member 9 on the outer diameter of the core tube 2, preventing the bearing member 9 from axially moving.
As an embodiment, the bearing member 9 is a deep groove ball bearing.
Specifically, two groups of deep groove ball bearings are arranged at intervals, and the middle of the deep groove ball bearings is positioned through a spacer ring 8.
The housing 11 is screwed to a slurry outlet connection 14 and is provided with a second sealing ring 12 at the circumferential end faces that are in contact with each other.
Specifically, the outer circumferential side of the housing 11 is externally threaded to mate with an internal thread on the inner wall of the slurry outlet fitting 14.
In one embodiment, the second seal ring 12 is a hydraulic pneumatic O-ring rubber seal.
In one embodiment, the slurry outlet connection 14, the housing 11 and the gland 7 are all in a reverse threaded fit.
The circumferential side surface of the core pipe 2 is provided with a side water inlet joint 6, and the opening of the side water inlet joint 6 is provided with a matched plug 5.
The side inlet joint 6 is suitable for use in all directions and at multiple angles, and can not cause the water inlet pipe to be excessively bent.
And a third sealing ring 4 and a fourth sealing ring 3 are respectively arranged at the joint of the core pipe 2 and the side water inlet joint 6 and the joint of the core pipe and the slurry inlet joint 1.
In one embodiment, the third seal ring 4 is a combined seal ring, and the fourth seal ring 3 is a nylon seal ring.
In one embodiment, the slurry inlet joint 1 is a male joint, and the slurry outlet joint 14 is a reducer joint.
In the water tap assembly for geological exploration, when the water tap assembly works, slurry pumped by a slurry pump enters from a slurry inlet joint 1, passes through a core pipe 2, and enters a drill rod from a slurry outlet joint 14 (the slurry outlet joint 14 can be changed according to the specification of the drill rod), in the using process, the drill rod rotates to drive a gland 7, a spacer ring 8, a bearing piece 9 and a shell 11 to rotate together, other components are in a static state, and three first sealing rings 13 arranged on the core pipe 2 can effectively prevent the bearing from being damaged due to the fact that the slurry enters the bearing. The slurry outlet joint 14, the shell 11 and the gland 7 are in reverse thread fit, and the tighter the slurry outlet joint rotates.
When first sealing washer 13 needs to be changed, only need with gland 7 unscrew can, easy operation, it is efficient.
As shown in fig. 3, which is a schematic view of an existing faucet structure, a sealing member in the drawing generally adopts a mechanical sealing structure with a rotation fit, and includes a sleeve 16 sleeved with a rotary joint and a sealing sleeve 15 rigidly and sealingly connected with the sleeve 16, contact surfaces of the sleeve 16 and the sealing sleeve 15 are sealing surfaces, and in a construction process, the sleeve 16 rotates along with a connector 18, so that two contact surfaces of the sleeve 16 and the sealing sleeve 15 are tightly attached to achieve a rotary sealing effect, but due to vibration, a fine gap is generated on the attachment surface, so that impurities in water enter the sealing surface, and the sealing surface is damaged. Coupled with the large pressure experienced by the housing 17 and the high speed rotation of the sleeve 16, the faucet seal wears very quickly and has a short life and requires frequent replacement.
The sleeve 16 and the sealing sleeve 15 are consumable materials, the contact surface is processed into a mirror surface structure by adopting an alloy ring, the cost is high, and a single worker cannot replace the consumable materials on the basis without using a special tool, so the installation is laborious. And because the outer shell 17 of high pressure tap all adopts fixed connection's mode, the shell 17 end is fastening for it is very big to dismantle the degree of difficulty when changing shell 17 accessory, needs to spend a large amount of time to dismantle the accessory that is worn and torn, changes the accessory of renewal again, seriously influences the efficiency of construction.
The tap subassembly for geological exploration of this embodiment replaces original mechanical seal (alloy ring) with O type circle is sealed, greatly reduced the cost, avoided vibrations to cause the problem that the crackle leads to sealed face to damage, the in-service use effect is fine, and continuous operation 1500 hours need not change O type circle. When needing to be changed, can twist off gland 7, easy operation. In addition, the shell 11 and the core tube 2 of the embodiment are rotatably connected, and in the working process, the shell 11 rotates, and the core tube 2 is in a static state, so that the reliability is high.
