Fluoroplastics valve used with glass container

Abstract

The invention relates to a fluorin plastic valve matched with the glass vessel, comprising a valve body, a cone-shaped valve core and a joint sleeve; wherein, the central section of the cone-shaped valve core is provided with a liquid outlet through hole and an intake through hole in parallel, and the outer surface of the central section of the cone-shaped valve core is provided with a groove; an upper liquid outlet hole is correspondingly arranged inside the valve body at the upper end of the liquid outlet through hole and a lower liquid outlet hole is correspondingly arranged inside the valve body at the lower end of the liquid outlet through hole; an upper air inlet hole is correspondingly arranged inside the valve body at the upper end of the intake through hole and a lower air inlet hole is correspondingly arranged inside the valve body at the lower end of the intake through hole; a handle is connected with the large diameter end of the cone-shaped valve core, and a thread locking cap is connected with the minor diameter of the cone-shaped valve core; the upper end of the joint sleeve is connected with the lower end thread of the valve body. The invention has the advantages that: the structure is simple, the use is convenient, the corrosive liquid high pure reagent can be transported to the use position through the pipeline under the airtight condition, so as to avoid the pollution produced through the high pure material contacted with the air, the invention can be disassembled to clean, which does not affect the use.

Description

technical field [0001] The invention relates to the technical field of valves, and relates to a fluoroplastic valve matched with a glass container. Background technique [0002] Corrosive liquid chemicals are usually stored in glass containers and provided to the user. The liquid enters and exits through the bottle mouth, which is sealed by a plastic bottle cap. For solutions with low purity, high chemical stability, and no special requirements during use, the above-mentioned supply methods can meet the requirements of the users. However, for the extremely high purity (for metal impurities, the reagent purity reaches more than 89), the quality is easily affected by environmental factors, and the user has special requirements during use, the above packaging is obviously not suitable. The main disadvantages of the above-mentioned packaging are: firstly, the quality of the reagent liquid will change when the reagent liquid is in contact with the air after opening the bottle ca...

Problems solved by technology

However, for the extremely high purity (for metal impurities, the purity of the reagent reaches more than 89), the quality is easily affected by environmental factors, and the user has special requirements during use, the above packaging is obviously not applicable

The main disadvantages of the above-mentioned packaging are: firstly, the quality of the reagent liquid will change when the reagent liquid is in contact with the air after opening the bottle cap, and this change is serious for the user; secondly, it cannot be continuously and stably controlled. flow; third, the capacity of a single package is limited, and increasing the capacity of a single package will bring greater application difficulties to users
