Rotary quick-opening device for pressure vessel

Abstract

A rotary quick-opening device for a pressure vessel, comprising a head, an upper flange and a lower flange connected with a tank body, the aforementioned upper flange is arranged at the port of the aforementioned head, and the aforementioned upper flange is evenly distributed with upper flanges along the circumferential direction. Flange teeth, the aforesaid lower flange is uniformly distributed with lower flange teeth along the circumferential direction, and it is characterized in that the device further comprises a swivel ring arranged on the outer circumference of the aforementioned upper flange and the lower flange, and the upper end of the swivel ring has the same The upper flange teeth are matched with the locking upper teeth, and the lower end has lower teeth matched with the aforementioned lower flange teeth for locking. Compared with the prior art, the advantage of the present invention is that the rotation of the quick-opening cover is replaced by the locking and loosening of the rotating ring, so that there is no need for relative rotation between the upper flange and the lower flange, and the wear of the sealing ring is relatively small. In addition, only the lifting and lowering of the quick-opening cover is considered, without considering the rotation factor, so the requirements for the fixing structure of the quick-opening cover are relatively small, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a rotating and quick door opening device for the pressure vessel, which can be applied to pressure vessels such as vulcanization tanks, shaping tanks, sterilizing pots, and autoclaves. Background technique [0002] Existing pressure vessels, such as vulcanization tanks, shaping tanks, sterilizing pots, autoclaves, etc., whether they are horizontal or vertical, basically include a tank body and a quick-opening cover arranged at the port of the tank body. The quick-opening cover includes a sealing The upper flange and the upper flange welded to the end of the head. There are teeth on the lower flange evenly distributed in the circumferential direction of the flange. The teeth of the upper flange and the teeth of the lower flange are overlapped and locked. Opening, this kind of staggered teeth opening and closing structure requires relative rotation between the upper flange and the lower flange...

[0002] Existing pressure vessels, such as vulcanization tanks, shaping tanks, sterilizing pots, autoclaves, etc., whether they are horizontal or vertical, basically include a tank body and a quick-opening cover arranged at the port of the tank body. The quick-opening cover includes a sealing The upper flange and the upper flange welded to the end of the head. There are teeth on the lower flange evenly distributed in the circumferential direction of the flange. The teeth of the upper flange and the teeth of the lower flange are overlapped and locked. Opening, this kind of staggered teeth opening and closing structure requires relative rotation between the upper flange and the lower flange during the process of opening and closing the cover, which has the following disadvantages: First, the sealing ring is easily worn by the friction of the upper flange; Considering both lifting and turning, the fixing structure of the quick-opening cover is relatively complicated
