Carbide Dispense Valve Needles Spray Nozzles

The utility model relates to an injection-type dispensing valve which reduces wear between the firing needle and the nozzle

The invention relates to a method for manufacturing an injection-type dispensing valve which reduces wear between the firing needle and the nozzle

The existing way of dispensing fluid is generally needle dispensing, also known as contact dispensing, which is mainly through a certain gas pressure to push the fluid through a variety of needles with different pore sizes for dispensing operations, the size of the amount of glue depends on the size of the pressure and the diameter of the needle.

Jet glue valve on the market at present, there are many shortcomings, for example, firing pin in the opening and closing, the return spring pressure and nozzle closure repeatedly, so as to realize the spray adhesive solution, firing pin with nozzle repeated friction, but due to the firing pin, nozzle is metal material products, a hard surface, the firing pin and nozzle friction between two contact surface again and again will cause the loss of the surface material, namely parts geometry size of the result of the fatigue failure.After a long time of wear and tear, the following conditions will generally occur:

1, the firing needle, nozzle wear intensified, service life greatly shortened;

2. After the contact surfaces of the firing needle and the nozzle are worn and have gaps, when the firing needle is quickly reset upward, the glue liquid in the nozzle cavity will move upward with the firing needle under the action of pressure, affecting the normal work of the injection valve.

Therefore, the existing technology remains to be improved and developed.

In view of the shortcomings of the above existing technology, the purpose of this technology is to provide a spray type dispensing valve, aiming at solving the problem of easy wear of the firing needle and nozzle.
