Rotary dispensing valve

Abstract

The invention relates to a rotary dispensing valve. The rotary dispensing valve comprises a valve body, a cylinder, a spindle and a regulating valve, wherein the cylinder comprises locking screws, a cylinder body and a cylinder rotating shaft, the cylinder body is connected with the valve body through the locking screws, and a through hole I and a through hole II are formed in the valve body; the inner side wall of the through hole I is communicated with the inner side wall of the through hole II; the spindle is arranged in the through hole I and connected with the valve body through a bearing I; a through hole III is formed in the spindle; when the rotary dispensing valve is opened, the through hole III is communicated with the through hole II, the spindle is connected with the regulating valve, the cylinder rotating shaft is fixedly connected with the spindle, and a glue barrel connecting shaft is arranged at an upper port of the through hole II. The rotary dispensing valve has the advantages as follows: a fluid is cut off rapidly, the problems of wire drawing and match end are effectively solved, the fluid waste is greatly reduced, the cost is saved, and further, the rotary dispensing valve has good sealing performance, high dispensing precision and high anti-wearing property as well as an obvious advantage in the aspect of processing of the fluid containing hard particles.

Description

technical field [0001] The invention relates to the field of medium and high fluid valves, in particular to a glue dispensing rotary valve. Background technique [0002] With the continuous development of the economy and the continuous progress of science and technology, all kinds of equipment used in industry are developing in the direction of intelligence, high integration and high efficiency to meet the requirements of automated operations and achieve precision manufacturing Purpose. [0003] As we all know, in the existing dispensing mechanism, the dispensing rotary valve is prone to fluid drawing or matchhead phenomenon when medium and high-speed fluid passes through, resulting in waste of fluid, increased cost, unsightly equipment, and caused The dispensing accuracy is not high, and the wear resistance is low. Contents of the invention [0004] The technical problem to be solved by the present invention is: in order to effectively solve the problems of fluid drawin...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to effectively solve the problems of fluid drawing and match heads that are easy to occur in the dispensing rotary valve through medium and high-speed fluids, the present invention provides a dispensing rotary valve, which adjusts the main shaft through the regulating valve, so that The through hole three on the main shaft is connected with the through hole on the valve body, and the external energy is used to quickly cut off the fluid passage, effectively solving the problem of fluid matchheads in wire drawing machines
