一种低残留Y型保温取样装置
By designing a Y-type heat-insulated sampling device with an eccentric valve stem, an arc-shaped valve stem head, and an inclined sampling channel, the problems of media deposition and residue were solved, achieving smooth media outflow and accurate sampling. It is suitable for transesterification reactions in non-phosgene polycarbonate production processes.

AI Technical Summary
Existing sampling valves are prone to media deposition and residue, leading to inaccurate sampling, complicated operation, and affecting product quality.
A low-residue Y-type heat-insulating sampling device was designed, which adopts an eccentric setting of valve stem and valve body, with the arc-shaped structure of valve stem head fitting into the flow channel of valve body, and the sampling channel is designed with an inclination. Combined with a lightweight flat bearing and quick conversion connector, it ensures smooth flow of medium and reduces installation height.
It effectively reduces media residue, improves sampling accuracy, simplifies operation procedures, and reduces environmental pollution risks. It is suitable for transesterification reactions in non-phosgene polycarbonate production processes.
