Abstract
An air channel control valve of a down-the-hole drill impactor comprises a valve body, a valve sleeve, an end cover and a valve element. The valve body is provided with a high-pressure air inlet and a high-pressure air outlet which are communicated through a channel in the valve body, the valve sleeve is installed in the channel, the valve element is installed in the valve sleeve, one end of the valve element is connected with high-pressure oil, the other end of the valve element can seal the channel between the high-pressure air inlet and the high-pressure air outlet, and the high-pressure oil is connected with an oil tank through the control valve. The air channel control valve of the down-the-hole drill impactor is simple in structure, low in cost and capable of controlling the down-the-hole drill impactor to be opened or closed and achieving the drilling function.
Description
Technical field
The utility model 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 starts to hole, impactor needs weak the impact to carry out perforate, to guarantee Kong Zhidu.What control at present the impactor impact 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.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure for the deficiencies in the prior art, and cost is low, can realize controlling the hidden hole drilling impactor and open and close, and can realize the hidden hole drilling impactor gas path control valve of perforate function.
The utility model 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 is 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 described valve body, in described passage, valve pocket is installed, in 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 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 utility model adopts the mode of dynamic hydraulic combined, hydraulic pressure cavity high pressure when impactor is not worked, control valve closure; When impactor needs work, hydraulic pressure cavity is led to oil return, and under the effect of high pressure air, control valve is opened, owing to there being 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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, comprise valve body 1, valve pocket 2, end cap 3, spool 4, two-bit triplet solenoid valve 5, throttle valve 6.When impactor is not worked, two-bit triplet solenoid valve 5 is in left position, and spool 4 firmly seals 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, makes suction port identical with air outlet, under the throttling action of throttle valve 6, spool 4 moves comparatively slowly, flow area between suction port and air outlet increases gradually, and the impact energy of impactor slowly increases, thereby realizes the perforate function of impactor.
