1, Product Definition
The integrated argon pressure regulator is an integrated valve body structure consisting of a pressure reducing valve, a pressure gauge, and a rotor flow meter. It integrates pressure reduction and stabilization, pressure display, and precise flow control into a single integrated valve body, without the need for separate assembly. It is a gas cylinder pressure regulator specifically designed for argon arc welding and inert gas supply, commonly known as an argon flow meter or an integrated argon pressure reducing valve in the industry.
2, Core structure composition (integrated)
Inlet high-pressure valve body: G5/8 standard gas cylinder interface, built-in copper filter screen to filter impurities; High pressure gauge 0~25MPa, displaying the remaining gas volume of the steel cylinder
Pressure reducing and stabilizing components: single-stage/two-stage pressure reducing diaphragm structure, reducing the high pressure of the gas cylinder from 15MPa to the welding low pressure of 0.1-0.35MPa
Integrated glass rotor flowmeter: integrated series valve body, range 0~25L/min, with flow fine adjustment needle valve, precise control of protective gas flow rate
Air outlet interface: 6/8mm hose quick connect, directly connected to argon arc welding gun pipeline
Safety structure: Built in overpressure safety valve, automatic pressure relief and explosion-proof when the pressure exceeds the standard
3, Core Product Advantages (Integrated vs. Split)
Compact structure and easy installation
Integrated casting, with internal valve body in the pipeline and no external adapter, reducing leakage points; A single person can directly screw it onto the mouth of an argon gas cylinder, making it easy to disassemble and assemble.
More stable gas supply and smaller flow error
The internal flow channel is straight through without any transfer resistance, and the flow fluctuation is minimal when the pressure of the gas cylinder drops. The stainless steel/brass core seal is stable, eliminating weld porosity and blackening defects.
Durable and durable, resistant to welding spatter
The valve body is chrome plated brass as a whole, and the flow meter is equipped with an impact protection cover. It is not easy to be damaged by long-term welding in the workshop; There is no issue of missing scattered accessories.
Intuitive operation, dual-use for one meter
A single instrument can simultaneously monitor the remaining pressure inside the bottle and real-time gas flow rate, with pressure and flow adjustment zoning knobs, making it easy for beginners to use.
Space saving and portable
The volume ratio of the assembled pressure reducer is reduced by 40%, and it has strong adaptability to mobile welding machines, construction sites, and small processing workshops.
4, Two mainstream structural selections
1. Single level integrated (universal economy type)
Applicable: Ordinary stainless steel TIG welding, sporadic welding in stores, simple gas supply in laboratories
Features: Low cost, fast response to voltage regulation; After a significant decrease in cylinder pressure, there is a slight fluctuation in flow rate
Representative model: YQAr-731L single flow meter model
2. Dual level integrated (precision industrial version)
Applicable: Precision welding of aluminum/titanium alloys, high-purity argon for semiconductors, automated welding assembly lines
Features: Two stage stepped pressure reduction, gas cylinder reduces from 15MPa to 0.5MPa, and the flow fluctuation throughout the entire process is ≤± 2%; Oil free internal structure, does not pollute high-purity argon gas
