组件规格

定义
A calibrated helical spring used in pressure-regulating valves to provide the counterforce against fluid pressure, enabling precise pressure control by compressing or extending to adjust the valve opening based on system pressure variations.
工作原理
Works on Hooke's law (F = kx), where spring force opposes fluid pressure to position the valve, maintaining a set pressure by dynamically balancing forces; compression increases with rising pressure to close the valve, and extension decreases with falling pressure to open it.
材料
Stainless steel (AISI 302/316 for corrosion resistance)music wire (ASTM A228 for high strength)or Inconel (for high-temperature applications)typically with tensile strength of 2000-3000 MPa and surface coatings like zinc or nickel plating.
Diameter
5-50 mm
End Type
Closed and ground
Free Length
20-150 mm
Spring Rate
10-100 N/mm
Pressure Range
0.5-20 bar
Operating Temperature
-40°C to 200°C
标准
ISO 10243DIN 2098

常见问题

What is the primary function of a control spring in a pressure regulator?

It provides a counterforce to fluid pressure, enabling the regulator to maintain a set pressure by adjusting the valve position dynamically.

How do I select the right control spring for my application?

Consider pressure range, spring rate, material compatibility (e.g., corrosion resistance), temperature limits, and compliance with standards like ISO 10243.

What are common failure modes of control springs?

Fatigue from cyclic loading, corrosion in harsh environments, and permanent set due to over-compression, leading to inaccurate pressure control.
