Description
Technical field
The utility model relates to the suction valve of air compressor, and is particularly relevant with the structure of cylinder, valve body, spool and the connection seat of suction valve.
Background technique
At present, the suction valve of domestic air compressor generally adopts the spring breather cheek valve and the butterfly valve of passive-type, and the unlatching of this class air valve valve need rely on external force to be used for realizing.Wherein, the unlatching of spring breather cheek valve valve needs against the force of the spring, and the air inlet pressure drop is bigger, influences the efficient of compressor, and spring is in yield situation for a long time fatigue fracture easily takes place simultaneously, and suction valve was lost efficacy; Butterfly valve is to drive the butterfly valve rotating vane rachis that rotates by drive unit to come a certain angle of back rotation to come control valve to open and close and charge flow rate, but complex structure, volume are bigger, and slow movement, and opening/shutting valve is slower, in only being applicable to, the large air compressor system.
The model utility content
The utility model provides a kind of air compressor suction valve structure, and this suction valve is simple in structure, compact, and intake resistance is little, and noise is low, valve opening and closing rapidly, and large, medium and small type air compressor all is suitable for.
Realize that the technological scheme that purpose of the present invention is taked is: a kind of air compressor suction valve structure comprises cylinder, valve body, spool, connection seat, and described cylinder is made up of cylinder body and cylinder cap, and cylinder body and cylinder cap and valve body are connected and fixed; Described spool is made up of piston rod, piston, valve, the piston of spool and valve fuse by piston rod and place respectively in cylinder, the valve body, and piston moves in cylinder, and cylinder is separated into upper and lower two chambeies, epicoele has the aperture that communicates with atmosphere, and cavity of resorption is communicated with cylinder cap; Described cylinder cap has hole and the ventilation interface that internal diameter is different and be interconnected; Divide upper and lower cavity in the described valve body, and the ventilation interface is all arranged, porose connection between two cavitys can be separated upper and lower cavity when moving on on the valve; Two holes and the interface of ventilating that described connection seat has three internal diameter differences to be interconnected, two holes are communicated with valve body cavity of resorption, main frame suction port respectively, and the ventilation interface is communicated with the smart device that divides of oil gas; Described cylinder cap ventilation interface and valve body cavity of resorption ventilation interface are communicated with lower chamber of air cylinder and valve body cavity of resorption by outer connecting pipe, described cylinder, valve body, connection seat fuse, and drive the rapid opening and closing valve of valve by valve core piston under negative pressure and compressed-air actuated effect.
The upper and lower cavity of described valve body is communicated with by conical bore.
The piston rod of described spool and valve are an integral body, and the rubber closure plate is arranged on the valve, and this rubber closure plate is conical.
Adopt the present invention, when host-initiated, solenoid directional control valve gets, the cylinder head ventilation interface of suction valve and valve body cavity of resorption ventilation interface are communicated with lower chamber of air cylinder and valve body cavity of resorption by outer connecting pipe, after the main frame operation, form negative pressure in the cavity that the suction valve cylinder is communicated with valve body rapidly, spool is moved down, valve opening, ambient atmosphere enters main frame through valve body epicoele ventilation interface, valve and connection seat.When compressor power cuts off, the commutation of solenoid directional control valve dead electricity, the cavity passage that the cylinder of suction valve is communicated with valve body is blocked at once, pressurized air enters lower chamber of air cylinder through cylinder head ventilation interface, the promotion valve core piston moves up, valve is closed conical intercommunicating pore between valve body two cavitys rapidly, makes main frame under situation about not stopping operating fully, stops pressurized air and lubricant oil in the main frame to return atmosphere through the suction valve adverse current.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an OX-1/8 scroll type air compressor suction valve section of structure.
Embodiment
With reference to Fig. 1, this scroll type air compressor suction valve structure comprises cylinder, valve body, spool, connection seat 7.Cylinder is made up of cylinder body 1 and cylinder cap 3, and cylinder body 1 and cylinder cap 3 usefulness screws and valve body are connected and fixed; Described spool is made up of piston rod 4, piston 2, valve 5, the piston 2 and the valve 5 of spool fuse by piston rod 4 and place respectively in cylinder, the valve body, piston rod 4 is an integral body with valve 5, and rubber closure plate 14 is arranged on the valve 5, and this rubber closure plate is conical.Piston moves in cylinder, and cylinder is separated into upper and lower two chambeies, and epicoele 8 has the aperture 9 that communicates with atmosphere, and cavity of resorption 10 is communicated with cylinder cap 3; Described cylinder cap has hole and the ventilation interface 11 that internal diameter is different and be interconnected; Divide upper and lower cavity 12,15 in the described valve body, and all have between ventilation interface 13,16, two cavitys and have the conical bore hole to be communicated with, can separate upper and lower cavity 12,16 when moving on on the valve 5; Two holes 17,18 and ventilation interface 19, two holes 17,18 that described connection seat has three internal diameter differences to be interconnected are communicated with valve body cavity of resorption 15, main frame suction port respectively, and ventilation interface 19 is communicated with the smart device that divides of oil gas; Described cylinder cap ventilation interface 11 and valve body cavity of resorption ventilation interface 16 are communicated with lower chamber of air cylinder and valve body cavity of resorption by outer connecting pipe, described cylinder, valve body, connection seat 7 fuse, and drive valve 5 rapid opening and closing valves by valve core piston 2 under negative pressure and compressed-air actuated effect.
