SAT-Q32S model
Dual-seat high-pressure safety valve set-pressure calibration bench
This model of safety valve pressure‑setting test bench is equipped with a built-in automatic gas booster that delivers rapid pressurization with low noise, enabling medium‑pressure gas to be boosted to high pressure. It is used for the pressure‑setting verification and leak‑tightness testing of high‑pressure safety valves.
Scope of Application
- Calibration of high-, medium-, and low-pressure safety valves with a rated pressure PS ≤ 32 MPa (optional maximum calibration pressures of 40 MPa, 45 MPa, 50 MPa, 60 MPa, and 70 MPa are also available);
- Flanged safety valves, DN20–200 mm (with optional maximum test diameters of DN250 mm and DN300 mm);
- ZG'/2"～2*/2" inch‑threaded safety valve;
- Various full-lift and pilot-operated safety valves;
- Flanged safety valves of various thicknesses and shapes;
- Commonly used metric and imperial threaded safety valves;
- Domestic and imported safety valves.
Equipment Features
- Equipped with an automatic gas pressure‑boosting system, it can directly increase medium‑pressure gas from 4 to 15 MPa to high pressure.
- Dual‑seat pneumatic clamping mechanism, offering convenient and rapid operation.
- The small‑diameter seat‑clamp foot employs a synchronized, linked eccentric‑disc mechanism, eliminating the need to install a centering pad during calibration. It accommodates various nominal diameters, offering high efficiency, convenience, and speed while conserving compressed air.
- The large‑diameter seat features a continuously adjustable clamping force that can be tailored to different nominal diameters and pressures, making it suitable for the calibration of medium‑ and high‑pressure safety valves.
- Dual‑scale display, featuring a four‑range precision pressure gauge switching mechanism that adjusts according to the magnitude of the calibrated pressure.
- A dedicated low‑pressure calibration system for pressures below 1.0 MPa is provided, making the verification of low‑pressure safety valves more convenient and accurate, while also protecting precision pressure gauges with small measurement ranges.
- All operating valves in the equipment, including calibration valves, pressure relief valves, and pressure switching valves, are aerospace‑grade industrial valves.
- The safety guard plate for the high-pressure safety valve has been configured, significantly enhancing safety performance.
- The equipment is equipped with a safety valve and features an automatic overpressure‑triggered opening protection mechanism.
