AI Technical Summary

Benefits of technology

The technology described by this inventor allows for better capturing of electrical energy from windings with improved performance compared to existing methods that only use one type of fluid (air). This results in higher power output per unit area or reduced size of the device due to less coolant being used during operation.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of an evaporation type vacuump (vaccum pumps) without causing blockages or damaging products during its operation.

Embodiment Construction

[0026] The overall design concept of the present invention is that the main isolation valve of the vacuum freeze dryer adopts a relatively movable double valve plate structure to form a double airflow distribution form, which realizes reasonable guidance of the airflow flowing from the freeze-drying box to the cold trap, The distribution of the double airflow can make the airflow more uniform and improve the overall capture efficiency of the cold trap coil.

[0027] Cooperate Figure 1-3 As shown, the main isolation valve of the vacuum freeze dryer of the present invention includes a large valve plate 3 with openings and a small valve plate 7 positioned on one side of the large valve plate 3; the large valve plate 3 and the small valve plate 7 can be Relatively slide along the axial direction of the hole; when the main isolation valve is in the open state, a double annular airflow is formed; when the main isolation valve is in the closed state, the small valve plate 7 can cove...

Abstract

The invention discloses a main isolating valve of a vacuum freeze dryer. The main isolating valve comprises valve plates, the valve plates adopt a double-valve-plate structure capable of relatively moving and comprise the large valve plate with an open hole and the small valve plate located at one side of the large valve plate; when the main isolating valve is in a switch-on state, double streams air flow are formed; when the main isolating valve is in a switch-off state, the open hole of the large valve plate can be covered with the small valve plate. The invention further discloses the vacuum freeze dryer with the main isolating valve. According to the main isolating valve adopting the double-valve-plate structure capable of relatively moving, air flow flowing from a freeze-drying box to a cold trap is reasonably guided, double-stream air flow distribution is achieved, the overall capture efficiency of a cold trap coil pipe is improved, the working efficiency and quality of the vacuum freeze dryer are improved, and the main isolating valve is suitable for application and popularization.
