Problems solved by technology

For this reason, although the flow rate can be adjusted with high precision, the workability is poor. When performing continuous operations, there is a problem that it is difficult to change the flow rate midway.
Therefore, the minimum number of ventilation ports must be compatible with all the expected work contents, and there are problems of increasing the size of the device and complicating the control.
[0011] In addition, in the mass flow, since the gas flow rate can be adjusted based on the flow rate information stored in advance, a stable flow rate of gas can be reliably supplied, but there are problems in that the configuration of the device is complicated and the price is high.

Abstract

This invention provides a flow amount adjustment apparatus able to adjust flow amount with high reliability at a low cost without being oversized. The flow amount adjustment apparatus has a plurality of orifices having different bore diameter for a predetermined flow amount, respectively, the orifices being opened and closed by an open-close member, respectively; a primary piping connected to each of the orifices for supplying gas adjusted to a prescribed pressure; and a secondary piping connected to each of the orifices for gathering gas passed through an opened orifice or a plurality of opened orifices, wherein one orifice or a plurality of orifices capable of satisfying a prescribed flow amount are selected and opened.

Description

【Technical field】 [0001] The present invention relates to a flow rate adjustment device for adjusting the flow rate of gas supplied to a welding torch when cutting or welding a workpiece with gas injected from a processing torch, and a processing device using the flow rate adjustment device. 【Background technique】 [0002] When cutting and processing steel plates, use plasma cutting torches, laser cutting torches or gas cutting torches, and use plasma processing torches when cutting, grooving or welding ferrous metals such as steel plates or stainless steel plates, or non-ferrous metals such as copper plates or aluminum plates Or a laser processing torch, use a laser processing torch when cutting, grooving wood or plastic panels. [0003] As a representative example of this processing, the case of cutting a steel plate will be described. For example, when cutting a steel plate with a plasma cutting torch, the plasma gas is supplied around an electrode provided on the plasma ...
