Abstract
An air channel control valve of a down-hole drill impactor comprises a valve body, a valve sleeve, an end cover and a valve core, wherein the valve body is provided with a high-pressure air inlet and a high-pressure air outlet; the high-pressure air inlet and the high-pressure air outlet are communicated through a channel in the valve body; the valve sleeve is mounted in the channel; the valve core is mounted in the valve sleeve; one end of the valve core is connected with high-pressure oil, and the other end of the valve core can be used for sealing the channel between the high-pressure air inlet and the high-pressure air outlet; the high-pressure oil is connected with an oil tank through the control valve. The air channel control valve is simple in structure and low in cost, and can be used for controlling the down-hole drill impactor to be opened or closed and achieving a holing function.
Description
Technical field
The present invention relates to a kind of hidden hole drilling impactor gas path control valve.
Background technique
Down-the-hole drill is widely used in the every field such as mining, metallurgy, building, machining, carries out the Drilling of foundation construction, tunnel excavation, exploration, quarrying, mining blast hole.The equipment of the hidden hole drilling of impactor, when hidden hole drilling began to hole, impactor needed weak the impact to carry out perforate, to guarantee Kong Zhidu.What the control impactor impacted at present is a kind of solenoid valve, slowly opens valve port when hidden hole drilling is started working, and impact energy is slowly increased.But in use find, this solenoid valve poor reliability, and price is higher.
Summary of the invention
The object of the invention is to provides a kind of simple in structure for the deficiencies in the prior art, and cost is low, can realize that control hidden hole drilling impactor opens and closes, and can realize the hidden hole drilling impactor gas path control valve of perforate function.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of hidden hole drilling impactor gas path control valve, comprise valve body, valve pocket, end cap and spool, described valve body are provided with high pressure air import and high pressure air outlet, described high pressure air import and high pressure air outlet are by the channel connection in the described valve body, in the described passage valve pocket is installed, in the described valve pocket spool is installed, an end of described spool is connected with high pressure oil, described passage between the salable described high pressure air import of the other end and the high pressure air outlet, described high pressure oil is connected with fuel tank by control valve.
Described control valve is the two-bit triplet solenoid valve, and the return opening of described two-bit triplet solenoid valve is connected with described fuel tank by throttle valve.
Adopt said structure, the present invention adopts the mode of dynamic hydraulic combined, hydraulic pressure cavity high pressure when impactor is not worked, and control valve is closed; When impactor needed work, hydraulic pressure cavity was led to oil return, and control valve is opened under the effect of high pressure air, owing to there is throttling, the control valve spool slowly moves, and the high pressure air flow that enters impactor slowly increases, the impactor impact energy slowly increases, thereby realizes the perforate function.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1, a kind of hidden hole drilling impactor gas path control valve comprises valve body 1, valve pocket 2, end cap 3, spool 4, two-bit triplet solenoid valve 5, throttle valve 6.When impactor was not worked, two-bit triplet solenoid valve 5 was in left position, and spool 4 seals firmly by dead valve pocket stroke under the effect of right-hand member high pressure oil, and suction port and air outlet cut off; When impactor needs work, two-bit triplet solenoid valve 5 is in left position, spool 4 right-hand members lead to oil return, spool moves right under the effect of high pressure air, so that suction port is identical with the air outlet, under the throttling action of throttle valve 6, spool 4 moves comparatively slowly, flow area between suction port and the air outlet increases gradually, and the impact energy of impactor slowly increases, thereby realizes the perforate function of impactor.
