The essence of PVC Foot Valve is a kind of vacuum suction film, which can be generally divided into soft and hard, used for the surface packaging of all kinds of panels, so it is also known as decorative film, adhesive film, used in building materials, packaging, medicine and many other industries, among which the building materials industry accounts for a significant proportion, followed by the packaging industry. The water supply pipe system is the clamp connection, thread connection, hole connection three systems are integrated, the installation is fast and simple and reliable.
PVC chemical and physical properties of foot valve: Rigid PVC is one of a wide range of plastic materials. PVC is actually a vinyl polymeric substance, and its material is a non-crystalline material. For PVC materials, in practical use, they often add stabilizer, lubricant, auxiliary processing agent, color material, impact resistance agent and other additives. With non-flammability, high strength, gas tolerance and variability and excellent geometric stability. PVC is highly resistant to oxidants, reductants, and strong acids. However, it can be corroded by concentrated oxidized acids, such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
Characteristics of foot valve: the PPH Foot Valve is a kind of energy saving valve, generally installed at the bottom of the pump underwater straw, limit the liquid in the pump pipe back to the water source, playing only in not out of the function. There are many intakes and reinforcement on the bonnet, which are not easy to block, mainly used in pumping pipes. The role of waterways and supports. The caliber has single, double, multivalve types, with flanged and threaded connections.
The CPVC Foot Valve design is reasonable, advanced manufacturing technology, convenient installation, use and maintenance. And has the advantages of small friction resistance, long service life, energy saving, widely used in petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, drainage and irrigation and other industries of water pump supporting facilities.
