Seal device for ultra-high pressure contain

Abstract

The invention relates to the sealing device field, in particular to a sealing device for an ultrahigh pressure vessel. A chock plug is connected with a barrel of the ultrahigh pressure vessel by a screw thread. The tail end of the chock plug, which is close to one side of the interior of the barrel of the ultrahigh pressure vessel, is an inclined plane. The inclined plane coincides with a triangular washer of the sealing device to realize first resealing. The tail end of the chock plug is a cylinder. The chock plug is screwed into the interior of the barrel of the ultrahigh pressure vessel by the screw thread. The cylinder part of the chock plug coincides with an alloy ring, an O-shaped ring, a square-shaped ring and the like of the sealing device to realize second sealing. The sealing device has moderate softness and hardness, hard wearing, high pressure resistant property, and good sealing effect. The sealing device is arranged on a groove of the inner wall of the ultrahigh pressure vessel, is difficult to drop off and resistant to wear, has long service life and simple operation, and saves cost.

Description

technical field [0001] The invention relates to the field of sealing equipment, in particular to a sealing device for ultra-high pressure containers. Background technique [0002] The sealing structure of the ultra-high pressure container is an important part of the entire ultra-high pressure food processing equipment. The effective operation of the food pressurization device will depend on the selection of sealing materials and the reasonable sealing structure. To measure the advantages and disadvantages of the ultra-high pressure sealing structure, it is mainly based on the following principles: under normal working conditions, the sealing effect of the container is guaranteed; the structure is simple, and it is convenient to manufacture, assemble, disassemble and overhaul; Less space; the required fasteners are simple and light in structure to reduce the weight of the equipment; good durability. [0003] Several common sealing devices are: [0004] a. Forced sealing: su...

AI Technical Summary

Problems solved by technology

Due to the large capacity, high pressure and large caliber of food ultra-high pressure containers, coupled with the inevitable frequent opening and closing during food processing, the external seal is deformed or worn, and it is easy to fall off from the head, requiring frequent loading and long service life. Short, and seals are difficult or unable to withstand high pressure due to improper material selection
