Lightweight Dispensing Valve for Low to High Viscosity Gels with Stable Glue Output
Machine Introduction
The single tube screw valve is a precision volumetric metering and conveying product, which is suitable for various high-precision quantitative conveying occasions. The single-component screw pump adopts spiral structure design, the screw and stator are self-sealing design, the screw rotates in the stator cavity to achieve quantitative conveying function. The conveying process does not produce shear effect on the medium and does not affect the characteristics of the medium. At the same time, it can be sucked back by the motor in the reverse direction, which can easily break the glue and perfectly solve the problem of dripping and pulling in the dispensing process.
1. Volumetric fluid conveying
2.Servo motor drive
3.Eccentric spiral rotor for micro application
4. Stator with excellent corrosion resistance
5. Lightweight dispensing valve for micro application dispensing
6. Suitable for gels from low to high viscosities
7. Stable glue output and high dispensing accuracy
8. No dripping or pulling problems
Working Principle
1. The volumetric metering and filling system of the single tube screw valve (single part screw valve) is based on the infinite piston principle, with a hermetic design between the rotor and stator, and the rotor rotating inside the stator core to achieve the quantitative delivery of the colloid for fluids of low to high viscosity of the liquid.
2. The core of each application is based on volumetric delivery metering pumps, which can ensure pressure stability and the linear characteristics of the pump, determining the relationship between pump speed, time and flow rate, so that constant material can be metered either by time or by the pump's rotational speed.
3. From low to high viscosity, abrasion resistant and highly filled fluids that are sensitive to structure, dispensing is not affected by viscosity.
