Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Such as figure 1 A special valve for microsphere dispersion suitable for diagnostic reagents, including a valve seat assembly 1, a valve core assembly 2 is connected below the valve seat assembly 1, and its difference lies in that: in order to form a flow-limiting slit, it does not need Adopting a traditional impact ring structure, the valve core assembly 2 includes a valve core body 3 , and the top of the valve core body 3 is a conical structure 4 . In this way, the impact force and shear force can be reduced to an acceptable level during actual use. In other words, with such a configuration, the shearing force between the valve seat and the valve plug can be alm...

Abstract

The invention relates to a valve special for microsphere dispersion and suitable for a diagnostic reagent. The valve comprises a valve seat assembly. The lower portion of the valve seat assembly is connected with a valve element assembly. The valve element assembly comprises a valve element body. The top of the valve element body is of a conic structure. A connecting ring is distributed on the valve element body. A conic containing cavity is formed in the valve seat assembly. The conic structure of the top of the valve element assembly is in contact with the conic containing cavity. The top ofthe connecting ring is in contact with the bottom of the valve seat assembly. The conic containing cavity is connected with a machining channel in a communicating manner. Thus, the top of the valve element body is of the conic structure, an impact ring is omitted, it can be guaranteed that impact force and shear force borne by microspheres during homogenization are within an acceptable range, andintegrity of the microspheres is guaranteed. Through mutual cooperation of the conic containing cavity and the machining channel, the length of a runner is increased, the dispersion stroke is increased, the work area is enlarged, and a good dispersion effect is achieved. The overall structure is simple, and assembling is easy.

Description

technical field [0001] The invention relates to a special valve, in particular to a microsphere dispersion special valve suitable for diagnostic reagents. Background technique [0002] The homogenizing valve is an important component of the homogenizing machine. The material is sucked and pressurized by the plunger pump, and enters the pressure-adjustable valve group under the action of the plunger. After passing through the flow-limiting slit of a specific width, the material that loses pressure instantly is ejected at a very high flow rate, and collides with the On the collision ring of one of the valve components, a cavitation effect, an impact effect, and a shear effect are generated, thereby achieving the dispersion of the diagnostic reagent. [0003] However, there are still very few special valves for dispersing microspheres of diagnostic reagents on the market, and almost none of the homogenizing valves on the market can homogenize the microspheres of diagnostic rea...
