Abstract
The utility model relates to a novel drilling water faucet, in particular to a drilling water faucet used on a geological drilling rig. A water inlet elbow pipe (1) is connected with an outer casing (7) as a whole, a U-shaped sealing ring (2) is arranged between a water faucet core (6) and the middle part of the outer casing, a bearing assembly (5) is arranged between the middle parts, and a framework seal (4) is arranged at the upper part of the bearing assembly, and the utility model is characterized in that a water discharge opening (3) is arranged on the outer casing between the framework seal (4) and the U-shaped sealing ring (2). The water discharge opening (3) is arranged on the outer casing between the framework seal (4) and the U-shaped sealing ring (2), when mortar leakage happens, the circulation mortar is blocked to get into the bearing assembly when getting the lower part through the U-shaped sealing ring, and then is discharged outside the outer casing through the water discharge opening, therefore the bearing assembly is always operated in clean environment, the abrasion of the mortar to the bearing assembly is effectively prevented, and the service life is greatly improved.
Description
Technical field
The utility model relates to probing water tap used on a kind of geological drilling rig.
Background technology
The probing water tap is mounted in geological drilling rig kelly upper end and is used to connect hose and drilling rod, and the recycle slurry that water pump is sent here is delivered to the boring equipment at the end.The top of present probing water tap water inlet elbow and lower bearing assembly are a sealing integral body that communicates, though design has several roads seal between upper and lower cavity, the spillage that is used for intercepting top water inlet elbow enters bearing assembly, to stop the wearing and tearing of bearing assembly.But in fact,, but, the water tap pressure inside is constantly increased, force mud to enter bearing assembly along with continuous increase, the accumulation of spillage amount in case after spillage occurring, the slurry that is leaked can not flow out outside the water tap at once.Because of recycle slurry generally is the mixture of water and mud, after in a single day it enter bearing assembly, can make bearing ball accelerated wear test, cause the bearing clearance to increase, bearing assembly is damaged, produce swing during the rotation of water tap core, the damage cycle of accelerating consumable accessory.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind ofly can effectively stop recycle slurry to enter bearing assembly, can improve the water tap a kind of novel probing water tap in application life greatly.
The implementation of the utility model purpose is, a kind of novel probing water tap, water inlet elbow 1 is an integral body with shell 7, between water tap core 6 and the shell middle part U-shaped sealing ring 2 is arranged, bearing assembly 5 is arranged between the bottom, reinforced seal 4 is arranged at bearing assembly top, has spilled water hole 3 on the shell between reinforced seal 4 and the U-shaped sealing ring 2.
The utility model has spilled water hole 3 on the shell between reinforced seal 4 and the U-shaped sealing ring 2, when spillage occurring, when recycle slurry arrives the bottom through U-shaped sealing ring 2, will be stoped by reinforced seal 4 and enter bearing assembly, and outside spilled water hole 3 is discharged to shell 7, bearing assembly is worked in the environment of cleaning all the time, effectively prevent of the wearing and tearing of spillage silt, improve application life greatly bearing assembly.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
With reference to accompanying drawing, between the utility model water tap core 6 and the shell middle part U-shaped sealing ring 2 is arranged, bearing assembly 5 is arranged between the bottom, reinforced seal 4 is arranged at bearing assembly top, has spilled water hole 3 on the shell between reinforced seal 4 and the U-shaped sealing ring 2.
The utility model has spilled water hole 3 on the shell between reinforced seal 4 and the U-shaped sealing ring 2, when spillage occurring, when recycle slurry arrives the bottom through U-shaped sealing ring 2, will be stoped by reinforced seal 4 and enter bearing assembly, and outside spilled water hole 3 is discharged to shell 7, bearing assembly is worked in the environment of cleaning all the time, effectively prevent of the wearing and tearing of spillage silt, improve application life greatly bearing assembly.
