The closing valve is closed by controller progress, and the closed purpose of the cavity can be realized.When not needing using institute
When stating cavity and being kept the temperature, cavity injection is carried out to the cavity by opening the closing valve, and using air pump
Realize that the vacuum state of the cavity is switched to the purpose of non-vacuum.Or by water pump be the cavity in infused
Water can also switch over the vacuum state of the cavity.
To avoid the electromagnetism of the closing valve from failure conditions occur, in one embodiment, by the tracheae with
Connecting rod channel is set between the cavity, the connecting rod channel connects motor for placing telescopic rod, described telescopic rod one end, when
When needing the cavity being set as vacuum state, be evacuated by air pump, the gas in the cavity by connecting rod channel and
Gas is discharged in the cavity tracheae, and after gas drains, the telescopic rod is lifted up by the motor, the envelope
Open end of the top surface of valve closing door then with the cavity is bonded, and the closing of the cavity thus can be realized.When needs are cut
When being changed to non-vacuum, the telescopic rod is stretched downwards using the motor, the top surface of the closing valve is left described
The open end of the open end of cavity, the cavity is opened, and the open end that gas then passes through the cavity enters in the cavity, then
The switching of the non-vacuum of the cavity is completed, or the cavity is realized to filling the water in the cavity by water pump
Non-vacuum switching, since in the injecting process, there are air or oxygens in water, therefore, the cavity can be then in
Non-vacuum.
