Product Features：
The turntable type automatic flame welding machine for four - way valves is specifically designed for the multi - welding - point welding requirements of large and complex workpieces such as four - way valves. It adopts an innovative eight-station intelligent turntable layout, realizing fully automated production of the whole process from loading, precise inspection, sequential welding of four welding points, gradient cooling to automatic unloading. The equipment is equipped with four sets of independently controlled gas systems and wire feeding mechanisms. Through the precise cooperation of the single Z - axis lifting system and the cylinder pushing device, it realizes intelligent position changing welding in a three - dimensional space, ensuring that each welding point can obtain the best welding position and process parameters. The unique automatic ignition function ensures the stability and reliability of the welding process. The optimized design of the eight stations increases the production efficiency by more than 300%. It is especially suitable for the batch production needs of large workpieces such as refrigeration valves and hydraulic components, redefining the new standards for complex welding with high precision and reliability.

FAQ

Q: 1. What types of four-way valves is this machine compatible with?

A: The machine is designed for brazing standard HVAC four-way reversing valves, typically made of copper or brass. It supports various sizes and pipe configurations, including 2-port, 3-port, and 4-port assemblies.

Q: 2. How does the rotary table improve production efficiency?

A: The rotary indexing table allows for multi-station operation-while one valve is being welded, others can be loaded or preheated. This parallel process minimizes downtime and boosts overall output in mass production settings.

Q: 3. Can this machine perform multi-point brazing in one cycle?

A: Yes. Equipped with programmable three-axis flame torch movement, the machine can perform multi-point brazing on complex valve structures within a single automated cycle, ensuring uniform heating and consistent weld quality.

Q: 4. Is the machine suitable for continuous, high-volume production?

A: Absolutely. The system is built for industrial-scale production with high cycle stability. It features automatic ignition, precise flame control, and PLC-based parameter programming for repeatable, reliable performance.

Q: 5. What safety and automation features are included?

A: The machine includes safety shielding, emergency stop functions, gas pressure monitoring, flame detection, and optional fume extraction. It also supports integration with wire feeders, robotic arms, and MES systems for full production line automation.
