Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection stand for internal components of a deflection hemispherical valve. Background Art

[0002] Fluid conveying pipeline systems in industries such as coal chemical, steel, and alumina utilize a wide variety of valves to shut off the conveyed media and regulate flow (pressure) to meet the control requirements of the process systems. These systems typically transport corrosive, two-phase, or three-phase fluids containing solid particles, often solid, liquid, or vapor. These fluids operate in harsh environments characterized by large pressure differentials, high flow rates, and conditions such as flashing, cavitation, vibration, and noise. Eccentric hemispheric valves are widely used in these applications due to their unique performance characteristics.

[0003] The core components of the eccentric hemispheric valve: the eccentric disc, valve seat, and valve stem are extremely susceptible to damage due to cavitation, erosion, abrasion, vibration, and the like, which can lead to functional failure. Therefore, during planned maintenance or emergency shutdown, it is necessary to quickly survey, inspect, and produce replacement parts for vulnerable parts at the equipment disassembly site based on the changes in the installation position and size of the spare parts, or conduct on-site inspection and calibration of new and old parts.

[0004] The eccentric valve disc in the core component has a complex spatial structure and high relative position accuracy of spatial dimensions. After it is manufactured, processed and assembled separately from the core component valve seat, how to detect its relative position accuracy is directly related to the functional realization of the eccentric semi-ball valve as a whole. However, there is usually no surveying and testing bench at the disassembly site of the eccentric semi-ball valve equipment, making it impossible to perform high-precision and accurate inspection of vulnerable parts.
