Working principle: the present invention uses the principle of orifice restriction in the cooling link of drill bit, makees being normally carried out bore expanded hole
When industry, water flow is shunted water flow by 1 two sides water flow through hole 104 of drilling rod body, and a part is delivered to cutter hub 6 and limit dress
It sets, water flow is delivered to cutter hub 6 and limiting device by axis 10 when low pressure water, at this time because of the power of the be applied to spool 2 of water flow pressure
Lower than spring 7a tension, valve deck 2 can not just be opened, and can not carry out mechanical hole reaming.
Another part is delivered to 1 front end of drilling rod body and flows out from connector 18, passes through front end nozzle 11 in the water flow of low pressure water,
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.
Apparatus of the present invention are assembled using following installation steps:
Step 1 is packed into spring 7b and sealing ring 4b in one end of piston bush 13, is inserted into piston 12, the end sleeve of piston 12
Enter sealing ring 4b, limited with retaining ring 5b, is finally packed into washer 15 in the other end of piston bush 13, is locked with silk plug 14, outside dress
