Embodiment Construction

[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] The structure of multi-component gas mixing device of the present invention is as figure 1 As shown, it consists of several gas input branches, air compressors, solenoid valve controllers and dry filter components. Each gas input branch includes a gas storage tank 1 for the gas to be mixed, a pressure reducing valve 2, a flow meter 3, a solenoid valve 4, and a one-way valve 5, wherein the gas storage tank 1 is connected to the flow meter 3 through a pressure reducing valve 2 , the other end of the flow meter 3 is connected to the air intake cover 6 of the air compressor through the solenoid valve 4 and the one-way valve 5 . The solenoid valve 4 of each gas input branch is connected with the solenoid valve controller 11, and the solenoid valve controller 11 is connected with the motor 10 of the air compressor. The pressure gauge 7 of m...

Abstract

The present invention relates to a kind of multi-component gas blending apparatus, comprising several gas import branches, air compressor for gas blending, electromagnetic valve and filtration drying component for gas purification, and the produced blended gases can be used for protective gases in metal melting. Each of the gas import branches comprises gas container of pending gases for blending, pressure-relief valve for adjusting gas export pressure, flowmeter for adjusting gas blending proportion, electromagnetic valve for controlling gas import and close according to the working condition of the air compressor and one-way valve. The gas container of the air compressor is used as a gas-blending chamber and several kinds of gases are fully blended in the chamber through moving of air compressor piston, which can be used after purification and dry. The present invention has simple structure, which can guarantee control precision of several gases blending proportion for safer use.

Description

technical field [0001] The invention relates to a multi-component gas mixing device, which can fully mix one or more small amounts of gas with air, and the generated mixed gas can be used as a protective gas during metal smelting to achieve the purpose of metal protection during smelting. Background technique [0002] Usually people need to mix specific gas and air in many occasions, for example, when cutting metal with acetylene, it is necessary to mix acetylene with air (oxygen), and when metal magnesium is smelted, it is necessary to mix some specific gas with air, etc. When this kind of gas is mixed, it is often necessary to control the ratio of various gases in the mixed gas to achieve the purpose of complete reaction and safe use. However, the existing gas mixing devices are either miniaturized, with insufficient capacity and precision; or complicated, with huge and expensive equipment; the precision and benefit of the device cannot be balanced. [0003] Gas mixing de...
