The Carbide Nozzle And Needle

Different dispensing valve accessories used materials and the corresponding principle

At present, there are many different kinds of dispensing valves on the market, such as efd precision dispensing, efd diaphragm valve, etc.In view of these dispensing valve has what kind of principle and applicable what kind of material dispensing, these several questions are worth discussing and understanding.

Spray valve system

Spray valve is a common valve, and spray valve can be subdivided into the following:

1. General spray valve:

Application principle: the spray valve can atomize extremely small amount of fluid and spray it in the oval range with a diameter of 4.3-50.8mm (0.17" -2.0 ") or a diameter of 165.1mm (6.5").

Applied materials: catalyst, coating material, grease, liquid flux, silicone, solvent, lubricating oil, ink.

2. Micro-spray valve:

Application principle: a low volume low pressure (LVLP) technique is used to produce uniform spray patterns with diameters between 1.6 mm (0.0625") and 19.1 mm (0.75").The design is innovative in that it USES a freely usable dispensing needle of 0.1mm-0.3mm (0.004"-0.013") instead of a standard spray nozzle.It condenses LVLP air used to spray paint into a uniform spray pattern that is 30% smaller than the standard spray valve configuration of efds.The injection valve's thimble is sealed directly at the bottom of the dispensing needle, which completely eliminates the problem of incorrect dispensing due to residual liquid.

Application materials: activator, paint, ink, liquid flux, oil, silicone, solvent.

3. Circulating spray valve:

Application principle: the circulating spray valve system can atomize and spray circular and strip shapes ranging from 5 mm to 30.4 mm without causing nozzle blockage and overspray.This unique spray system effectively prevents nozzle blockage.Its particularity lies in that the extra circulating pump ensures the uniform mixing of sediment in the whole operation process of the rubber valve.At the same time, the atomization pressure delay function, which can be set separately, can prevent nozzle blockage after each spraying, reduce maintenance times and reduce downtime.

Application materials: marking ink, paint, other mixed fluids.

4. Sterile spray valve:

Application principle: the sterile spraying valve system adopts low pressure low flow (LVLP) spraying technology, which is suitable for accurately controlling the spraying of medium and low viscosity fluids.The spray valve USES a small spray head to spray a circular uniform pattern with a diameter of 0.130"~ 0.75" (3.3mm ~ 19.1mm).For the sterile fluid sprayed with disinfection, the fluid flow without retention is realized.Fluid contact parts made of 316l stainless steel and teflon are suitable for cip (cleaning in place) and sip (disinfection in place) processes.

Application materials: salt solution, stent coating, silicone oil, solvent

5. Rotary spray valve:

Application principle: a precise pneumatic motor and low pressure low flow (LVLP) technology are applied to evenly spray medium and low viscosity fluids such as lubricants and coatings on the inner wall of the cylinder, with effective diameter ranging from 25.4 cm to 304.8 cm (1"~12").

Application materials: activator, catalyst, lubricating oil/agent, paint/paint, solvent.

Two, precision rubber valve system

1. Diaphragm valve:

Application principle: a special form of cut-off valve, its opening and closing parts are a diaphragm made of soft material to separate the valve body chamber from the bonnet chamber and the drive parts.Diaphragm valve is a flexible, it can be one of the diaphragm, bolting in compression, the compression is operating by the stem and move up and down, when the compression a rose, the diaphragm is exalted, and cause pathway, when compressed down, weir diaphragm pressure in the body (if the weir valve) or pressure in the bottom of the outline (if for straight-through), diaphragm valve is suitable for the switch and the throttle.

Application materials: uv glue, dye, paint

2. Piston valve:

Application principle: the piston valve is a valve that can meet various special regulation requirements.Its regulating function is realized by the axial movement of a cylinder similar to a piston in the valve chamber, and its stroke is consistent with the direction of water flow in the tube.No matter where the piston is, no matter where the water in the valve chamber moves to any position, the flow section in the valve chamber no matter where is the piston, is a ring, at the outlet to the axis contraction, so as to achieve the best cavitation prevention, so as to avoid the possible cavitation caused by throttling damage to the valve body and pipeline.

Application materials: lubricating glue and silica gel, etc

3. Needle firing valve:

Application principle: the closing position of the stainless steel needle is in the needle transfer head of the rubber valve, which avoids the occurrence of residual glue in the rubber valve during the dispensing interval.

Application materials: epoxy resin, lubricants, marking inks, solvents, uv and uv-cured photogels, adhesives, etc.

4. High pressure valve:

Application principle: with a unique stainless steel balance shaft design, it can withstand up to 2,500 psi (172 bar) fluid pressure.With the function of setting the stroke, it can avoid excessive amount of glue, adjust the suction force, and ensure that the width of the line and the size of the glue point are always the same.

Application materials: adhesive, grease, sealant, silicone.

5. Screw valve:

Application principle: the one-piece screw feeding function, which precisely controls the dispensing time, air pressure and screw speed, ensures that the precise and consistent solder joints are obtained in the case of alloy particles in the lossless solder.

Application materials: solder paste, particulate material, hot melt grease, silver paste.

6. Centrifugal spraying system:

Application principle: this system includes: a compact compact pneumatic motor, a reliable efd dispensing valve and a valvematetm controller.The rubber valve places the accurately measured fluid on the disc mounted on the motor. When the fluid is close to the disc edge, it is thrown out under the action of centrifugal force, forming a neat strip track on the inner wall of the parts.
