Technical field
The utility model relates to a kind of air compressor air outlet one-way valve, relates in particular to a kind of hydraulic open-air drill carriage air compressor air outlet one-way valve.
Background technique
The hydraulic open-air drill carriage is a kind of top hammer formula formula rig of open-air use.It is mainly used in the blasting boreholes operation of the rocks such as civil works, quarry, road engineering and middle-size and small-size opencut.Be mainly used in hard or in the bore operation of hard ore deposit rock, grade ability is strong, maneuverability can carry out bore operation at complex-terrain, energy consumption is low, drilling speed is high.The hydraulic open-air drill carriage is as a kind of technology-intensive product that integrates mechanical electronic hydraulic, although cost is high, high to the technical requirements of Operation and maintenance, it has the advantages such as efficient, energy-conservation with respect to pneumatic drilling machine, will become the development trend of open air drill rig.
Hydraulic open-air drill carriage air compressor system plays an important role in the drilling machine construction operation, provides compressed gas source by air compressor for oil mist lubrication, and also the rock drill for gas flushing and water smoke flushing provides compressed gas source.Guarantee that bore operation carries out smoothly.
For the domestic and international at present general design conditions of hydraulic open-air drill carriage air compressor system, most of rig air compressor system pipeline is more, its air compressor air outlet valve arrangement is simple, function singleness, oil cut-off valve is by other pipeline control break-make, and the pipeline of complicated layout makes the system pressure loss large, causes the rig whole hydraulic performance decline, cost of production is high, and when the production installation and maintenance operating difficulties.
The model utility content
Technical problem to be solved in the utility model provides a kind of can the realization suction port, leakage port, main air outlet and oil cut-off valve is controlled the integrated of gas outlet, and can reduce in a large number the hydraulic open-air drill carriage air compressor air outlet one-way valve of the use of pipeline and joint.
In order to solve the problems of the technologies described above, the hydraulic open-air drill carriage air compressor air outlet one-way valve that the utility model provides, comprise valve body, spool, spring and valve seat, in described valve body, be provided with the air-inlet cavity and the outlet chamber that communicate, described spool slides in the cavity that is inserted in described valve seat and described spring is located between described spool and the described valve seat, described spring action makes being communicated with of the described air-inlet cavity of described spool open and close controlling and described outlet chamber in described spool, described air-inlet cavity is provided with suction port and the control gas outlet that links to each other with the import of oil cut-off valve control gas, described outlet chamber is provided with the main air outlet that links to each other with the deaerator suction port, and the cavity of described valve seat is provided with the leakage port that links to each other with air compressor air intake pipe leakage port.
Described valve seat adopts oil resistant refractory seal pad and bolt to be installed on the described valve body.
Offer on the described valve body for fixing cylindrical hole.
The place, right angle of described valve body offers fillet or chamfering.
Adopt the hydraulic open-air drill carriage air compressor air outlet one-way valve of technique scheme, therefore, compared with prior art, the utlity model has following advantage: (1) the utility model exports suction port, main air outlet, leakage port, control gas integrated, makes the air compressor system overall structure compacter; Pipeline reduces, and the reliability of system is improved.(2) because the interior gas temperature of air compressor is higher, novel oil resistant refractory seal pad, the working life of having improved the air outlet one-way valve are adopted in this practicality.
In sum, the utility model is that a kind of can the realization controlled the integrated of gas outlet to suction port, leakage port, main air outlet and oil cut-off valve, and can reduce in a large number the use of pipeline and joint, simple in structure, installation and maintenance is hydraulic open-air drill carriage air compressor air outlet one-way valve easily.

Fig. 2 is plan view of the present utility model.
Fig. 3 is the connection diagram of the utility model in air compressor system.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, in valve body 1, be provided with the air-inlet cavity 12 and the outlet chamber 9 that communicate, spool 2 slides in the cavity 14 that is inserted in valve seat 4 and spring 3 is located between spool 2 and the valve seat 4, spring 3 acts on spool 2 and makes being communicated with of spool 2 open and close controlling air-inlet cavitys 12 and outlet chamber 9, air-inlet cavity 12 is provided with suction port 11 and exports 10 with the import 16 of oil cut-off valve control gas by the control gas that pipeline links to each other, outlet chamber 9 is provided with the main air outlet 8 that is linked to each other by pipeline with deaerator suction port 17, the cavity 14 of valve seat 4 is provided with the leakage port 7 that links to each other with air compressor air intake pipe leakage port 18, offer on the valve body 1 for fixing cylindrical hole 13, the place, right angle of valve body 1 offers fillet or chamfering, and bolt 6 passes valve seat 4 usefulness oil resistant refractory seal pads 5 with valve seat 4, spool 2 is fixed and seals with spring 3 and valve body 1.
