Testing of the Vertical Hydraulic Valve Test Bench.

To meet the demands for efficient, precise and intensive detection of small and medium-sized valves, the new Vertical Hydraulic Valve Test Bench adopts an innovative vertical four-column hydraulic structure design. With its core advantages of small footprint, wide adaptability, high detection accuracy and convenient operation, it precisely fits the batch quality inspection scenarios of small and medium-sized valves, filling the gap of traditional horizontal pressure testing equipment's large space occupation and inconvenient clamping of small valves. It has become an intelligent upgrade tool for valve manufacturing, equipment maintenance and quality inspection institutions.

The structural design is the core highlight of this equipment. The entire machine adopts a vertical integrated compact architecture, equipped with a top pressurization cylinder and a bottom claw-type positioning structure. The upper and lower parts work together to apply precise pressure, without the need for complex tooling assistance, and can quickly complete the clamping and fixation of various small and medium-sized valves. The unique vertical layout significantly reduces the equipment's floor space. Compared to the traditional horizontal pressure testing bench, the space utilization rate is increased by more than 60%. It perfectly meets the requirements of compact workstations and modular production lines in the workshop. At the same time, the horizontal beam at the top of the equipment supports 90° rotation adjustment, enabling quick completion of valve loading and unloading as well as angle switching. A single person can complete the entire operation, greatly simplifying the workflow.

The equipment has the ability to adapt to all types and various working conditions. It can fully cover flange-type, welding-type and threaded-type valves with specifications ranging from DN15 to DN300mm. It is compatible with various industrial valves such as ball valves, gate valves, globe valves and regulating valves. It supports multi-level pressure detection under normal pressure and medium-high pressure, with the maximum test pressure reaching up to 48 MPa. It can precisely simulate the actual operation status of the valves in industrial settings and complete all-dimensional quality inspection projects including shell strength, sealing performance and leakage detection. The equipment is compatible with various detection media such as water, air and kerosene. It can be flexibly switched according to the valve material and detection requirements, and is suitable for different industries' strict detection standards.

In terms of intelligent detection and stability, the equipment integrates a high-precision hydraulic control system and a digital monitoring module. The hydraulic transmission is smooth and uniform, and the pressure application, stabilization, and release are fully controllable throughout the process. There is no pressure shock, effectively avoiding damage to the valve body and sealing components. It is equipped with an intelligent touch PLC control system, which supports parameter self-definition setting, automatic pressure stabilization, timeout pressure release, and automatic data storage and analysis functions. It can display core data such as pressure curves and test duration in real time. The detection results are accurate and intuitive, and it can be exported as a standardized test report in one click, meeting the diverse needs of enterprises for batch quality inspection, factory verification, and third-party testing.

In addition, the equipment is equipped with a water circulation recycling and automatic hydraulic oil pressure relief system. The medium can be recycled and reused, with low energy consumption and environmental friendliness. It is also equipped with multiple safety protection devices, including automatic pressure relief in case of overpressure, immediate fault alarm, and comprehensive emergency shutdown protection, ensuring the safety of both the equipment and the operators. The core components of the entire machine use imported precision components, which are wear-resistant, corrosion-resistant, and have stable and long-lasting operation. They have a low failure rate and are easy to maintain. They can be used for long-term, high-frequency batch detection operations, helping enterprises achieve standardization, efficiency, and intensification in valve quality inspection.
