Description
Technical field
The present invention relates to needle mist valve technology field, in particular to a kind of high-precision needle mist valve.
Background technique
Needle mist valve is a kind of atomization coating valve for high, medium and low viscosity solution profile material, and liquid is become tiny water
Pearl, and be discharged with Sprayable, it is coated in a circular form, adapts to a variety of fluid liquids, such as three-proofing coating, UV glue, help weldering
The coated materials such as agent, paint, cleaning solution.Air pressure in usual aerosol can is much higher than atmospheric pressure, the liquid in container
Body is extruded because of air pressure, and liquid enters needle mist valve spray head part by conduit, and liquid is sieved the tiny droplet of poling simultaneously by spray head
It sprays, is formed by spraying, after being sprayed on wiring board, edge line is clear, no flash-point.
In the prior art, before glue atomization, the upward stroke by manually adjusting fixed setting needle, setting are needed
One fixed flow adhesive out, needs artificial observation to do different adjustings, there are smart when adjusting in different plastic emitting flow occasions
Spend lower problem；In addition, in spraying process, nozzle cap will appear that atomization is insufficient to lead to slight glue residue problem, lead to
The atomization of PLC controller control pressure is often needed to do corresponding deferred action.
Existing notification number is that the Chinese patent of CN202381233Y discloses a kind of novel atomized pintle nozzle match-ing parts, including needle
Valve, needle-valve body, needle-valve body top are equipped with the cavity for accommodating needle-valve, and cavity bottom is equipped with pressure chamber, and pressure chamber's side wall is equipped with will
The spray orifice that pressure chamber is connected to outer wall space, spray orifice are interspersed in double.When work, needle-valve is opened, and liquid medium is through needle-valve
Intracorporal cavity enters pressure chamber, is then sprayed by spray orifice.
But a kind of above-mentioned novel atomized pintle nozzle match-ing parts have the disadvantage in that in use, need to manually control needle
The movement of valve, liquid medium content is difficult to control identical when ejection, there is a problem of controlling precision lower.
Summary of the invention
