UPVC Plastic Check Valve working principle: the valve adopts double guide and stainless steel spring buffer technology, so that the noise reduction to achieve the purpose of noise elimination, prolong the service life, to ensure the quality of use.
PVC Check Valve characteristics:
(1) high working pressure: the working pressure of various materials at room temperature can reach 1.0Mpa.
(2) wide service temperature: the service temperature of UPVC is-20℃ ~ + 70℃;
(3) Good impulse resistance: UPVC has high mechanical strength and impact resistance.
(4) Small liquid flow resistance: smooth inner wall of the product, small friction coefficient, high transmission efficiency.
(5) Excellent chemical performance: this product is non-toxic, tasteless, acid and alkali resistance, corrosion resistance, with a wide range of use. The UPVC plastic Ball Check Valve is mainly used for the more corrosive strong acid, strong alkali and mixed acid of the liquid (gas) body circulation.
(6) Easy installation, good sealing: this product is light in quality, using bonding or welding, complete pipe fittings, simple construction, good sealing, small labor intensity.
PVDF Ball Check Valve is suitable for a variety of light and heavy industrial conditions and building pipelines. Plastic check valve is widely used in: electrical, paper, boiler, pharmaceutical, mining, chemical, mechanical equipment pipeline, electronic industry, urban construction and other fields.
I. PVDF Check Valve characteristics description: Material: PVDF (polyvinylidene difluoride) tasteless, smooth inner wall, curved curve. The PVDF check valve is installed with a plug connection and sealed with a solvent adhesive. Compared with other material pipe material is longer service life, safer! PVDF Swing Check Valve flow friction is small, greatly reduce the fluid drag and pump horsepower, good impact resistance, good mechanical strength and high; medium strike toughness, only the toughness deformation in a sudden attack. PVDF Wafer Check Valve is often used in chemical industry, light industry, mining and metallurgy, oil field, electronics, pharmaceutical, brewing, food processing, construction, civil upper and lower water and other fields, to play the role of conveying various corrosive medium and high purity medium, especially suitable for water treatment and environmental protection system. This product is corrosion resistant, acid and alkali resistance, can replace stainless steel, lining glue, galvanized pipe.
II. Characteristics of PVDF Ball Check Valve:
(1) High working pressure: the pressure is 1.OMpa at room temperature of 2OC.
(2) Good impact resistance: only produce toughness deformation in a sudden attack.
(3) The chemical performance of the product is stable and tasteless, which fully meets the health and safety requirements of the pharmaceutical, food and other industries.
(4) Fluid resistance is small, its inner wall is smooth, the curve is a circular arc, so the flow friction force is small, greatly reducing the system fluid drag and pump horsepower.
(5) Large use temperature range: the temperature range used is-4O ℃ ~ + 130℃.
(6) Long service life: this product can generally be used indoors for 50 years long, such as buried underground or in water, the life life will be longer, and there is no obvious corrosion.
(7) Simple installation and good sealing: the installation of this product adopts the plug type connecting solvent bonding seal, simple construction, fast curing speed, high bonding strength, to avoid the phenomenon of running in the general pipe, running, dripping, leakage.
(8) Light weight, save investment: the weight of PVDF is 1 / 7 of the steel, thus reducing the weight of the structure, reducing the labor intensity of workers, and reduce the consumption of raw materials, can greatly save the project investment.
