Tiny gap is generated between pipeline and cover board causes the vacuum environment in pump pond to be destroyed, and more influences normally making for pump pond
With.
Utility model content
The utility model be solve the problems, such as it is set forth above to the easy frosting of blind flange and pump pond vacuum environment be easily destroyed,
A kind of Cryo Heat Insulation pump pond high-vacuum insulation lid, including heat-insulating cover ontology are provided thus, and the heat-insulating cover ontology includes method
Blue lid, vacuum chamber upper shell, vacuum chamber lower shell, pump pond outlet tube and parectasis space, the vacuum chamber upper shell setting
On the top of blind flange, the lower part of blind flange is arranged in the vacuum chamber lower shell, and the pump pond outlet tube passes through on vacuum chamber
Cylinder, blind flange and vacuum chamber lower shell are simultaneously connected with three, and the lower end of the pump pond outlet tube is connected with pump connecting flange,
The upper end of the pump pond outlet tube is connected with pump pond liquid outlet flange, and the two sides of the pump pond outlet tube are provided with interior conversion and connect
Head and external conversion connector, are provided with corrugated stainless steel tubing between the interior crossover sub and external conversion connector, the interior conversion connects
Head, corrugated stainless steel tubing and external conversion connector match to form swelling transition space, are provided with one in the parectasis space
Layer heat insulation layer, is provided with cover board on the vacuum chamber upper shell.
Preferably, being provided with pump pond adapter tube and vacuum orifice on the heat-insulating cover ontology.
The beneficial effects of the utility model are: the structure design of the utility model is reasonable, the heat preservation of pump pond can be carried out effectively,
Preventing pump pond, there is the phenomenon that frosting in blind flange in use, while effectively can prevent from pumping during pumping out liquid
Occurring tiny gap between pond vacuum chamber upper cover plate and liquid outlet pipe is destroyed the vacuum environment for pumping pond.
Detailed description of the invention
