Embodiment
The present invention is described in further details with specific embodiment below, but the present invention is not only limited in detail below in fact
Apply example.
Embodiment
As shown in Figure 1-2, technical solution of the invention is as follows：One kind water spray drill bit, including provided with apex point end and peace
Fill the drill body at end；The apex point end of the drill body is provided with hole for water spraying 1, and installation end side wall is provided with least one centrifugation and supplied water
Device 2；The delivery outlet of the centrifugation water supply installation 2 connects by one along the axially extending water cavity of drill body with hole for water spraying 1；
The centrifugation water supply installation 2 includes a socket and is fixed on shell on drill body installation end, the shell it is outer
Surface is anchor ring, and the enclosure has toroidal cavity, be arranged with the toroidal cavity using the rotating shaft of drill body as
A pair of water pressurizing devices 3 of symmetry axis, the shell are provided with water filling port and the thread plug 4 to match with water filling port；
One is provided with the water pressurizing device 3 with the column water cavity 3.1 of a diameter of axis of the centrifugation water supply installation 2, it is described
Be provided with column water cavity 3.1 one close to drill body metallic piston 3.2；The metallic piston 3.2 passes through an extension spring 3.3 and institute
State the inner end connection of column water cavity 3.1；
The outer end side wall of water pressurizing device 3 is provided with the input port 3.4 connected with the toroidal cavity；
The inner face of the column water cavity 3.1 be provided with connected with input port 3.4 by pipeline the first water inlet 3.5,
The first delivery port 3.6 connected by pipeline with the delivery outlet of the centrifugation water supply installation 2；
The outer face of the column water cavity 3.1 be provided with connected with input port 3.4 by pipeline the second water inlet 3.7,
The second delivery port 3.8 connected by pipeline with the delivery outlet of the centrifugation water supply installation 2；First water inlet 3.5 and
The check valve for only allowing current to flow into the column water cavity 3.1 is provided with two water inlets 3.7；First delivery port 3.6 and
The check valve for only allowing current to flow out the column water cavity 3.1 is provided with two delivery ports 3.8.
Toroidal cavity lateral wall is pressed close in the input port 3.4.
The drift of extension spring 3.3 is less than 1/5th of the length of column water cavity 3.1.
