Embodiment Construction

[0027] The present invention will be further described below in conjunction with embodiment (accompanying drawing):

[0028] Such as figure 1 , 2 As shown, the two-stage combined sealing structure for ultra-high pressure of the present invention includes an ultra-high pressure cylinder 1 as the main bearing component, and an ultra-high pressure cylinder with a convex cylindrical structure packaged on the sealing end of the ultra-high pressure cylinder 1 through a bearing clamp 8. The container plug 2 is composed of low-pressure O-rings 6 for low-pressure sealing that are sequentially fitted on the inner extension end cylindrical surface of the ultra-high pressure container plug 2 and the inner cavity of the sealing end of the ultra-high pressure cylinder 1 from the inside to the outside. The first-level seal, the second-level seal formed by the metal seal ring 3 with ultra-high pressure sealing performance, and the sealing gland 7 packaged inside the low-pressure O-ring 6; th...

Abstract

The invention discloses a two-stage combined sealing structure for ultrahigh pressure. The structure is characterized by comprising an ultrahigh pressure cylinder serving as a main bearing part and an ultrahigh pressure container plug which is packaged at the sealing end of the ultrahigh pressure cylinder and is of a convex cylindrical structure, a first-stage seal consisting of a low-pressure O-shaped sealing ring for low-pressure sealing and a second-stage seal consisting of a metal sealing ring with ultrahigh-pressure sealing performance are sequentially sleeved on the cylindrical surface of the inner extending end, matched with the inner cavity of the sealing end of the ultrahigh-pressure cylinder, of the ultrahigh-pressure container plug from inside to outside, and a sealing gland is packaged on the inner side of the low-pressure O-shaped sealing ring; an annular clamping groove is machined in the sealing face, matched with the cylindrical face of the inner extending end, of the metal sealing ring, and an O-shaped ring is embedded in the annular clamping groove; and the sealing gland is buckled and pressed at the inner extending end of the sealing column through a gland screw.

Description

technical field [0001] The invention relates to ultra-high pressure thawing equipment in the food processing industry, in particular to a two-stage combined sealing structure for ultra-high pressure. The role of the sealing structure is to effectively seal the container of the ultra-high pressure thawing equipment in two stages. It is a key component of the container of the ultra-high pressure thawing equipment and an important part that affects the working efficiency, use effect and technical parameters of the ultra-high pressure thawing equipment. Directly It is a key indicator for meat thawing to determine whether the ultra-high pressure thawing equipment can reach the preset pressure. Background technique [0002] At present, in the food processing industry worldwide, the preservation of meat such as beef, pork, mutton, and seafood is mainly stored in cold storage, and imported meat is also transported in frozen form. However, when these frozen meats are processed or re...
