Abstract
The utility model discloses a single-base dual-airflow electromagnetic valve for plasma cutters, comprising two parallel electromagnetic valves arranged on one base, wherein the air inlets of the two parallel electromagnetic valves are communicated with a total air inlet and the air outlets are communicated with a total air outlet, the two electromagnetic valves comprise a large flux valve and a small flux valve. The single-base dual-airflow electromagnetic valve has reasonable structure, the ability for providing large and small air fluxes and good working effect.
Description
Technical field:
The utility model relates to a kind of cutting machine air feed valve.
Background technique:
At present, the striking of general plasma cutting machine must rely on HF (3000V～10000V, the high-frequency impulse of 100～200KHZ) the cutting plasma arc that ignites, its fatal problem is exactly easily electronic equipment to be produced stronger electromagnetic interference, therefore, its use is restricted, particularly with the supporting use of CNC, be very easy to the proper functioning of Interference Control computer, and digital cutting is the fast and very large production technology of application quantity of development at present, utilize two air-flows to control non-high frequency technique, address the above problem effectively, will reduce the electromagnetic interference of CNC greatly.Because the special construction principle of non-high frequency burning torch, its arc process is to rely on gas to push electrode and nozzle open non-short-circuit condition by short-circuit condition, and form (drawing) electric arc by guiding (PILOT) circuital current between them, thereby form PILOTARC (pilot arc is little arc); When the burning torch nozzle form again near workpiece and workpiece between the cutting minor arc, arc process is very responsive to the control of air-flow and striking electric current, crossing air flow and too little current all can can't the starting the arc or blow out electric arc, otherwise can damage electrode nozzle even rifle body fast and cause and can't normally cut.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and what the throughput that varies in size can be provided respectively is used for the two air-flow solenoid valves of plasma cutting machine single seat.
Technical solution of the present utility model is:
A kind of two air-flow solenoid valves of plasma cutting machine single seat that are used for, it is characterized in that: comprise the solenoid valve that is loaded on two parallel connections on the same pedestal, the suction port of the solenoid valve of two parallel connections communicates with a total suction port, the air outlet of two solenoid valves communicates with a total relief opening, one is large-capacity valve in two solenoid valves, and one is the rill metered valve.
The aperture of large-capacity valve is 5mm, and the aperture of rill metered valve is 2mm.
The utility model is rational in infrastructure, and the throughput that varies in size, good working effect can be provided respectively.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of two air-flow solenoid valves of plasma cutting machine single seat that are used for, comprise the solenoid valve 2,3 that is loaded on two parallel connections on the same pedestal 1, the suction port 4,5 of the solenoid valve of two parallel connections communicates with a total suction port 6, the air outlet 7,8 of two solenoid valves communicates with a total relief opening 9, one is large-capacity valve in two solenoid valves, and one is the rill metered valve.The aperture of large-capacity valve is 5mm, and the aperture of rill metered valve is 2mm.
