Connect upstream and downstream equipment and protect the effect of cable.
Both-way communication design in the past in pipe nipple (bcpm) water conservancy diversion protector slurry channel of powering is damaged by erosion corrosion easily
Bad, service life is short, and replacement frequency is high, and must synchronous changer connect and cable connectors when changing, complex steps.
Content of the invention
It is an object of the invention to solving above-mentioned technical deficiency, one kind is provided to be provided with flow deflector simultaneously in fluid passage upper end
In flow deflector and fluid passage surface coated cemented carbide coating, reduce fluid passage erosion corrosion, improve service life
Measurement while drilling logging system both-way communication power pipe nipple erosion resistance water conservancy diversion protector.
The utility model solves technical problem and be the technical scheme is that a kind of measurement while drilling logging system both-way communication
Power supply pipe nipple erosion resistance water conservancy diversion protector, powers pipe nipple erosion resistance air deflector body including both-way communication, both-way communication is powered short
Section erosion resistance air deflector body upper external cylindrical surface center be provided with endoporus one, endoporus one communicate therewith below be provided with one
The endoporus two tilting；It is provided with a conical drilling well in the middle and lower part that both-way communication powers pipe nipple erosion resistance air deflector body
Liquid passage it is characterised in that the upper end of fluid passage vertical be distributed with two trapezoidal flow deflectors；The table of flow deflector
Face is coated with hard alloy layer one, in fluid passage on be coated with hard alloy layer two.
The beneficial effects of the utility model are: this utility model, due to having filled flow deflector, reduces drilling fluid to equipment base
The erosion of body；In flow deflector and fluid passage surface spraying hard alloy layer, intensity is high, and wear-resistant erosion resistance prolongs significantly
Grow service life.
