by:Mech     2020-11-11

corrugated pipe cut-off valve in many industries, so want to ensure that its performance, reasonable design is the key to its, so we are all in the design of our need to consider what factors?

1. Corrugated pipe welding procedure qualification and welding quality records. 2. Metal corrugated tube valve in the opening and closing state bellows respectively in the compression and tensile state. 3. As bellows valve of throttle velocity should be considered for the influence of the bellows. 4. Corrugated pipe should be under pressure to the minimum thickness of laminated, and test requirements. 5. Corrugated pipe has certain rigidity, should consider bellows stretching or compressing the increase in operating torque. 6. As to the clearance between the Industrial Valves stem and bellows: 1 - 2mm。

so corrugated pipe cut-off Industrial Valves when designing consider these factors, to ensure the performance of the corrugated pipe cut-off Industrial Valves.
