In piston type stream commutator, the power of be applied to 12 tail portion of piston of water flow pressure is lower than spring 7b tension and 12 end of piston
When the sum of power, water will continue to move ahead, and push unidirectionally to spool 17, and by filter screen 19, water flow encounters at this time narrows suddenly
Section, due to declining the pressure of water flow sharply, corresponding to evaporating temperature also can accordingly decline, therefore liquid
It will evaporate at a lower temperature, evaporation process absorbs the heat of itself, to cool down to drill bit.
When the power of be applied to 12 tail portion of piston of water flow pressure in the piston-type underwater stream commutator of front end is higher than spring 7b tension
When closing with pistons end power, water flow just will push piston 12 and move ahead, compressed spring 7b, closes water flow and moves ahead, rear end limits at this time
At device spool 2 carried from the tension applied also above spring 7a, the spool 2 in limiting device will move ahead, and push
Ejector pin 8 releases limit, and high pressure water ejects to form reaction force from the nozzle 11 of cutter hub, it will be able to fill mechanical hole reaming
Opening is set, cutting effect is formed to media, with the increase of hydraulic pressure, the nozzle 11 of Counterboring apparatus front end is likewise supplied with high pressure water flow
Cutting effect promotes cutting efficiency.
