Preferably, a hole is opened at the top of the second cover and the control device body is embedded and installed, and the second cover is filled with heat insulating filler.

Preferably, the control device body is electrically connected to the drive device body, a touch screen is provided on one side of the upper surface of the control device body, and a power interface is provided on the other side of the upper surface of the control device body.

Preferably, the drive device body is designed with a servo motor material, and a screw is mounted on the bottom of the drive device body, and the screw rod passes through the center of the sealing gasket and is threadedly connected with the sealing gasket.

Preferably, a limit frame is provided at the bottom end of the inner wall of the second cover below the limit groove, and the inner wall of the limit groove is in contact with the outer wall of the gasket but is not fixedly connected.

Preferably, the outer side of the limiting frame is welded to the inner wall of the second cover, a bearing is provided at the center of the limiting frame, and the bottom end of the screw passes through the gasket and is fixedly connected to the inner wall of the bearing.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model sets the first cover and embeds and installs the second cover on the top of the first cover. At the same time, a sealing gasket is movably installed in the second cover, and the sealing gasket can slide up and down along the limit groove. Control the distance that the sealing pad moves up and down, and then pressurize the inside of the vessel, so as to achieve the effect of conveniently opening the low-temperature vacuum vessel.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example

As shown in Fig. 1, Fig. 2 and Fig. 3, an embodiment provided by the utility model: a rotating cover for a low-temperature vacuum pressure vessel, including a first cover body 2, and an inner wire is provided under the inner side of the first cover body 2 Screw thread 3, the outer side of the bottom end of the first cover 2 is slotted and embedded with a sealing ring 1. The outer side of the first cover 2 is provided with anti-skid ribs 12 in an annular array. The first cover 2 adopts a cylindrical structure design and the top is embedded with the second cover 5. The top of the second cover 5 has a hole and is embedded with the control device body 6. The second cover 5 is filled with heat insulating filler 8. .

The second cover body 5 is equipped with a driving device body 7, and the control device body 6 is electrically connected to the driving device body 7. One side of the upper surface of the control device body 6 is provided with a touch screen, and the other side of the upper surface of the control device body 6 is provided with a touch screen. power interface. The driving device body 7 adopts a servo motor material design, and the bottom end of the driving device body 7 is driven with a screw 10, and the screw 10 passes through the center of the sealing gasket 9 and is threadedly connected with the sealing gasket 9.
