Abstract
A keep-alive device of an air plasma cutting machine adopts the scheme that an air pressure switch, a first tee valve, a first electromagnetic valve, a second tee valve and a second electromagnetic valve are sequentially connected in the direction of airflow, wherein a keep-alive pipeline is arranged between the first electromagnetic valve and the second electromagnetic valve, and the second tee valve is connected with a cutting pipeline; and a throttle valve is arranged on the keep-alive pipeline. Since the throttle valve is arranged on the keep-alive pipeline, the volume of small air flow passing the second electromagnetic valve during the keep-alive process can be adjusted, so as to ensure even more continuous keeping alive of arc, small noise, and better reliability.
Description
Technical field
The utility model relates to Plasma Arc Cutting Technology, especially a kind of air plasma cutter, with and improved arc-maintaining device.
Background technology
As shown in Figure 1, in the prior art, throughput during throughput and the arc maintenance during cutting of isolating air plasma cutter with two magnetic valves of size, the throughput size can not be regulated again during the arc maintenance.Its shortcoming is: do not have flexibility, the user in use, owing to the reason source of the gas of each side when different, the air pressure that enters machine changes to some extent, the throughput size also can change during the arc maintenance.Machine can operate as normal when input air pressure is relatively low, because the throughput size also diminishes during the arc maintenance, and electrode and nozzle that like this can easy scaling loss cutting gun; When input air pressure than higher opportunity device can operate as normal because the throughput size also becomes greatly during the arc maintenance, like this arc maintenance understand discontinuous, noise greatly, poor reliability.
The utility model content
Technical problem to be solved in the utility model provides a kind of air plasma cutter arc-maintaining device, can regulate the throughput size during arc maintenance, make more continuous during the arc maintenance, noise is little, reliable better.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of air plasma cutter arc-maintaining device, be connected with baroswitch, first triple valve, first magnetic valve, second triple valve, second magnetic valve in turn by airflow direction, be provided with the arc maintenance pipeline between described first magnetic valve and second magnetic valve, described second triple valve is connected with the cutting pipeline; Described arc maintenance pipeline is provided with choke valve.Baroswitch detects the compressed air that enters machine, the air volume the during cutting of first solenoid control, the stingy flow size when the stingy flow during the second solenoid control arc maintenance, choke valve are contained in panel adjusted arc maintenance.Couple together by triple valve, connector tracheae etc. between them, when using different source of the gas air feed, the throughput during arc maintenance also can change, and can have influence on the effect of arc maintenance like this, can have influence on striking.As long as the needs when regulating choke valve and just can satisfy different source of the gas air feed allow arc maintenance effect protection optimum state.
As improvement, described choke valve is fixed on the panel of air plasma cutter, and the handled easily personnel carry out the adjusting of throughput at any time.
The beneficial effect that the utility model is compared with prior art brought is:
The arc maintenance pipeline is provided with choke valve, during arc maintenance, can regulate the size by the stingy flow of second magnetic valve, make more continuous during the arc maintenance, noise is little, reliable better.
Description of drawings
Fig. 1 is the air plasma cutter arc-maintaining device of prior art;
Fig. 2 is an air plasma cutter arc-maintaining device of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 2, a kind of air plasma cutter arc-maintaining device, be connected with baroswitch 1, first triple valve 6, first magnetic valve 2, second triple valve 7, second magnetic valve 4 in turn by airflow direction, be provided with arc maintenance pipeline 5 between described first magnetic valve 2 and second magnetic valve 4, described second triple valve 7 is connected with cutting pipeline 3, cuts pipeline 3 and chews with gas and be connected.Described arc maintenance pipeline 5 is provided with choke valve 8, and for the handled easily personnel carry out the adjusting of throughput at any time, described choke valve 8 is fixed on the panel (not indicating) of air plasma cutter.
Baroswitch 1 detects the compressed air that enters machine, the air volume during the 2 control cuttings of first magnetic valve, the stingy flow during second magnetic valve, 4 control arc maintenances, the stingy flow size when choke valve 8 is contained in panel adjusted arc maintenance.Couple together by triple valve 6,7, connector tracheae etc. between them, when using different source of the gas air feed, the throughput during arc maintenance also can change, and can have influence on the effect of arc maintenance like this, can have influence on striking.As long as the needs when regulating choke valve and just can satisfy different source of the gas air feed allow arc maintenance effect protection optimum state.
Claims (2)
