Embodiment 1

[0015] A homogeneous valve group, including a diamond valve seat 1, a diamond valve core 2 and a retaining ring 3, the diamond valve seat 1 is provided with a bump 11, and the bump 11 is provided with a flow limiting gap 12, the diamond valve The core 2 is a cylinder, and its end faces the flow-limiting slit 12 , and the end of the flow-limiting slit 12 facing the end face of the diamond spool 2 is bell-mouthed. Wherein, the retaining ring 3 includes a root portion 31 and an end portion 32; its root portion 31 is fixed on the outer edge of the diamond spool 2, and its end portion 32 protrudes beyond the end surface of the diamond spool 2 to form a joint with the bump 11 and the diamond spool 2. Collision ring. In practice, the material is ejected from the flow-limiting slit 12 and hits the end surface of the diamond spool 2 to generate a first right-angle shear. After changing the direction of movement, it hits the end 32 to generate a second right-angle shear and splashes out...

Abstract

The invention discloses a homogenizing valve group, comprising a diamond valve seat, a diamond valve element and a check ring, wherein a lug provided with a flow limiting gap is arranged on the diamond valve seat, the diamond valve element is cylindrical in shape, and the end face of the diamond valve element right faces the flow limiting gap; the check ring comprises a root portion and an end portion, the root portion is fixed on the outer edge of the diamond valve element, and the end portion stretches out of the end face of the diamond valve element to jointly form a collision ring with the lug and the diamond valve element; material is ejected out from the flow limiting gap, is subjected to primary right-angle shearing by impacting the end face of the diamond valve element, then subjected to secondary right-angle shearing by impacting the end portion after changing the motion direction, and is sputtered out of the collision ring. The homogenizing valve group is simple in structure and convenient to prepare. The protein yield after bacteria are crushed, the refining and homogenizing effect of nanometer materials is improved, the product stability is good and the reproducibility is high.

Description

technical field [0001] The invention relates to the technical field of biological protein extraction, in particular to a homogeneous valve group for improving the protein yield when bacteria are crushed in the biological industry. Background technique [0002] Cell homogenization refers to the process of using a homogenizing valve to refine and evenly mix materials. This technique is commonly used in the field of biochemistry to crush yeast extract protein and uniform nano-materials. In the prior art, the plunger pump is used to push the material into the flat homogenizing valve group, and the homogenizing valve group is used to pulverize the material to achieve homogeneous refinement and protein extraction. At present, there are two main materials for planar homogeneous valves: ceramics and hard alloys. Ceramics have high hardness and good wear resistance, but are highly brittle and easy to break. Moreover, they cannot be processed into right-angled edges to increase shea...
