Description
Technical Field
The utility model relates to the technical field of rotary valves, in particular to a novel connector rotary valve.
Background
The rotary valve is an indispensable dispensing valve in the dispensing industry, and the dispensing characteristics without large and small heads are relatively outstanding; the glue dispensing technology is generally applicable to the glue dispensing technology of middle-high viscosity glue and is also applicable to glue with partial filler; the ceramic rotary valve core has reliable service performance, and has the properties of high hardness, wear resistance, high temperature resistance, corrosion resistance and the like. The ceramic rotary valve adopts zirconia material to process, has self-lubricating function, changes the traditional mechanism of sliding friction and lubrication of a metal rod, and has long service life of a valve core; the high-precision internal and external circular grinding machine is used for processing the mirror surface, the appearance is subjected to vibration polishing, the cleaning is convenient, and the disassembly is easy. The method is mainly used for dispensing processes of conductive adhesive, heat-conducting silicone grease, silica gel and the like.
The traditional rotary valve connector consists of a connector male head and a connector female head, and the ceramic valve core component is directly and rigidly connected with the connector female head; the contact part of the male connector and the female connector is a square contact structure of the male connector; the structure has good strength.
However, if the concentricity of the central axis of the male connector and the central axis of the female connector is larger than the fit clearance of the ceramic valve core assembly during installation, an unrotatable area can be formed, and the ceramic valve core cannot be rotated; we therefore propose a new connector rotary valve to address this problem.
Disclosure of Invention
The present utility model is directed to a new rotary connector valve that solves the above-mentioned problems.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a new connector rotary valve comprising: the rotary valve comprises a rotary valve body, a connector male head, a connector female head and a ceramic valve core assembly, wherein the connector male head, the connector female head and the ceramic valve core assembly are all arranged on the rotary valve body, and the ceramic valve core assembly is directly and rigidly connected with the connector female head;
one side of the connector male head is provided with a circular contact structure, and the circular contact structure is used for being connected with the connector female head.
Preferably, an airtight rubber cover and a sealing end cover are arranged on the right side of the rotary valve body.
Preferably, the top of the rotary valve body is communicated with a glue barrel joint, the bottom of the rotary valve body is communicated with a dispensing needle head, and the top of the rotary valve body is provided with an air source joint.
In the rotary valve of the novel connector, after the square contact structure of the contact part of the male connector and the female connector is changed into the circular contact structure, the contact point of the male connector and the female connector only has one point, the point slides on the inner wall of the groove of the female connector, and a logic dead point that two points simultaneously contact on the same surface and the central line of the male connector and the female connector is not concentric does not exist in the square structure.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-4, a new connector rotary valve, comprising: the rotary valve body, the connector male head 1, the connector female head 2 and the ceramic valve core assembly 3 are arranged in the rotary valve body, and the ceramic valve core assembly 3 is directly and rigidly connected with the connector female head 2;
one side of the connector male 1 is provided with a circular contact structure 101, the circular contact structure 101 being adapted to be connected with the connector female 2.
In this embodiment, the right side of rotary valve main part is provided with airtight glue lid and sealed end cover, and the top intercommunication of rotary valve main part has gluey bucket to connect, and the bottom intercommunication of rotary valve main part has the point to glue the syringe needle, and the top of rotary valve main part is provided with the air supply and connects.
In this embodiment, when in use, by changing the square contact structure of the contact portion of the male connector 1 and the female connector 2 into the circular contact structure 101, the contact point of the male connector and the female connector only has one point, the point slides on the inner wall of the groove of the female connector, and no logic dead point exists in which two points on the same surface simultaneously contact and the center line of the male connector and the female connector are not concentric.
The above description is provided for a new connector rotary valve. The principles and embodiments of the present utility model have been described herein with reference to specific examples, which are intended to be merely illustrative of the methods of the present utility model and their core ideas.
