Small Portable High-Pressure Safety Valve Pressure-Setting Calibration Bench
This compact and versatile device facilitates mobile on-site service, enabling the set‑point adjustment of safety valve opening pressures and the testing of sealing performance.
Structural features
- Equipped with an automatic gas pressure‑boosting system, it can directly increase medium‑pressure gas from 4 to 15 MPa to high pressure.
- This equipment requires no external power; it integrates pressure boosting and calibration into a single system. The calibration unit and the pressure‑boosting unit can be stacked vertically to form a compact, mobile high‑pressure device, or operated independently, making it easy to transport and relocate.
- Equipped with a hydraulic lift work vehicle and a custom aluminum alloy toolbox, it facilitates transportation and on-site operations.
- A continuously adjustable clamping force ranging from 1 to 9 tons, tailored to different diameters and pressures;
- Dual precision pressure gauges provide more accurate calibration.
- The safety guard plate equipped with a high-pressure safety valve featuring verification functionality significantly enhances safety performance.
- Pneumatic clamping mechanism: clean, quick, low failure rate, and easy to operate.
- The operating valve is made of high-quality military-grade valves.
- The equipment is equipped with a safety valve and features an automatic overpressure‑triggered relief device.
- The equipment frame and worktop are made of stainless steel.
Technical Specifications
- Verification of the flow path range: (1-1) Flanged safety valves, DN20–200 mm; (1-2) Inch‑threaded safety valves, ZG 1/2"–2 1/2"; (1-3) Metric‑threaded safety valves, M27×1.5, M30×1.5, M33×1.5.
- Maximum test pressure: 32 MPa
- Verification accuracy: ±0.4%
Attention
- The verification medium shall be nitrogen or clean compressed air, with the medium source provided by the user.
- This device is not intended for use in verifying other valves.
