Valve Water Pressure Strength Test Bench Iso5208 Plc Touch Intelligent Water Pressure Testing Equipment
Product Introduction
The WPT-1 valve water pressure strength test bench achieves efficient detection of valve performance through precise pressure control and intelligent data management:
- Full range coverage: 0-60MPa adjustable pressure (standard pressure sensor accuracy ±0.5% FS), compatible with DN15-DN600 caliber valves, supports shell strength test (1.5 times nominal pressure) and sealing test (1.1 times nominal pressure).
- Intelligent control: PLC touch screen sets test parameters (pressure, pressure holding time, number of cycles) with one button, servo motor drives plunger pump to automatically increase/decrease pressure, pressure stability ≤±1% FS, avoiding manual operation errors.
- Safe and reliable: stainless steel high-pressure pipeline (pressure resistance 100MPa) with dual pressure protection (mechanical overflow valve + software overpressure shutdown), leak detection sensor real-time monitoring of the test bench surrounding environment to ensure operator safety.
- Data traceability: Built-in 16G memory, automatically records pressure-time curve, leakage, pressure holding pass rate and other data, supports USB export and host computer software analysis (generates PDF test report), and meets ISO 9001 quality traceability requirements.
Product Features
High-precision pressure control
- Servo motor + high-precision gear pump combination, pressure resolution 0.1MPa, pressure rise rate 0-5MPa/s adjustable, meet the ASME B16.34 test requirements for slow pressure rise.
- The pressure sensor is calibrated by CNAS, with an annual drift of ≤0.2% FS, ensuring long-term accuracy stability.
Multi-function test mode
- Supports single valve test and multi-valve parallel test (up to 8 stations), suitable for all types of valves such as gate valves, stop valves, ball valves, check valves, etc.
- Pressure holding time 0-240 minutes can be freely set to simulate long-term stability test under high pressure conditions.
Human-computer interaction optimization
- 7-inch color touch screen (Chinese and English switch), real-time display of pressure curve, temperature, leakage status, intuitive and easy to understand operation interface.
- Remote control interface (RS485/USB), supports PC-side software batch import of test solutions, improves the level of laboratory automation.
Safety protection design
- Transparent explosion-proof observation window (pressure resistance 50MPa), fully enclosed test area, automatically cut off power supply and sound and light alarm in case of leakage.
- Over-temperature protection (motor temperature>70℃ shutdown), water shortage protection (water tank liquid level below the warning line warning), reduce equipment loss.
International reference standards
- ASME B16.34: Valve pressure level and test method (shell strength, sealing performance test clauses).
- GB/T 13927: Industrial valve pressure test standard (pressure holding time, leakage determination rules).
- API 598: Valve pressure test specification (specify the temperature and medium requirements of water pressure test).
- ISO 5208: Industrial valve leakage test standard (gas/liquid leakage detection method).
Product use
- Valve manufacturing: shell strength and sealing performance sampling inspection before leaving the factory to ensure that the valve meets the nominal pressure level (such as PN16, PN63 valve inspection).
- Pipeline engineering: re-inspect the valve before installation to avoid leakage risks under high-pressure conditions (such as natural gas pipeline, chemical process valve inspection).
- Quality inspection agencies: provide third-party inspection reports and support compliance testing for valve CE and API certification.
- Research institutions: research on the pressure resistance of valve materials (such as pressure-deformation curve analysis of stainless steel and cast iron valves).
