The High-Pressure Cycle Test System for Large-Caliber Valves Has Been Awarded a National Patent

The self-developed high-pressure cycle testing system for large-diameter valves of our company has been verified on-site to achieve efficient and accurate testing. It serves as a core link in valve design verification (cycle testing refers to life testing, and its requirements vary with different valve specifications).
Compared with most enterprises that only have low-pressure cycle testing capabilities, our company has significant advantages: we not only possess a low-pressure testing system covering the full range of 3-108 inch valves, but also have high-pressure testing capabilities — including a 3-72 inch high-pressure system. Meanwhile, in response to customer needs, we have developed a 250PSI high-pressure system suitable for 78-108 inch large-diameter valves. The system has been upgraded in terms of materials, component selection and structure (for example, the water circuit uses seamless steel pipes with an outer diameter of 108mm and a wall thickness of 5mm, and the selection of components meets the system's maximum pressure and flow rate requirements). In addition, it is equipped with a built-in data acquisition and control system, which can automatically record test data.
At present, this high-pressure system has completed the testing and verification of 96-inch and 84-inch valves. It features stable and reliable performance, meets high-pressure design requirements, and has obtained a national utility model patent. It provides key technical support for the design verification of large-diameter valves in the industry.
