Fluorine-lined valve Applicable medium for fluorine-lined diaphragm valve

Fluorine-lined valve Suitable medium for fluorine-lined diaphragm valve Fluorine-lined diaphragm valve -Applicable medium Any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc. Operating temperature: -85~150 Features: Mechanical, electrical properties and chemical stability are basically the same as F4, but the outstanding advantages are high dynamic impact toughness, excellent weather resistance and radiation. Polytrifluoroethylene PCTEF (F3) Applicable medium: various organic solvents, inorganic corrosive liquids (oxidizing acids) Operating temperature: -195~120 Features: heat resistance, electrical properties and chemical stability are second only to F4, mechanical Strength, creep performance and hardness are better than F4 Polypropylene: RPP Applicable medium: aqueous solution of inorganic salts, inorganic acids, dilute or concentrated solutions of alkalis. Operating temperature: -14~80 Features: One of the lightest plastics, its yield, tensile and compressive strength, and hardness are better than low-pressure polyethylene, with outstanding rigidity, good heat resistance, easy to form, and cheap. After modification, it has dynamic impact, fluidity, and bending elasticity. Polyvinyl chloride: rigid) PVC Applicable medium: water resistance, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc. Use temperature: 0-55 Features: high mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and aging resistance, easy welding and bonding, low price. Polytetrachloroethylene PTFE (F4) Use medium: strong acid, strong alkali, strong oxidant, etc. Use temperature: -200~180 Features: Excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, is an excellent self-lubricating material, but has low mechanical properties, poor fluidity, thermal expansion Big. Polyvinylidene chloride PVDF (F2) Use medium: resistant to most chemicals and solvents, use temperature: -70~100 Features: tensile strength and compressive strength are better than F4, bending resistance, weather resistance, radiation resistance. Light resistance and aging, etc., the biggest feature is good toughness and easy molding. Polyolefin: PO Applicable medium: various concentrations of acid and alkali salts and some organic solvents. Operating temperature: -58~80 Features: It is the most ideal anti-corrosion material in the world at present, and has been widely used in the lining of large-scale equipment and pipe fittings for rotational molding. Fluorine-lined diaphragm valve: 1. This valve is composed of valve body, valve cover, valve stem, valve disc, diaphragm, and other driving parts. 2. The opening and closing of the valve is achieved by the connecting shaft of the electric device driving the valve stem nut, so that when the valve stem moves axially, it drives the valve disc to rise and fall. 3. When the power supply fails and is interrupted, and the valve needs to be opened and closed urgently, firstly, the hand-electric switching handle should be switched to the position marked with the manual mark, and then the flash door can be opened and closed by rotating the handwheel. When turned clockwise, the valve can be closed; otherwise, it will open. 4. When the electric operation needs to be restored, the switching handle must be switched to the position marked with the electric mark before electric operation can be carried out.
At a time when technology is essential for valve application, ensuring that it works in a symbiotic way with your human employees is key.
Lianke Valve Co.,Ltd.’s mission is to provide high quality care and services to our members and to be profitable in the process.
Lianke Valve Co.,Ltd. deems valve application as evolutionary rather than revolutionary. We've always had these 'social commerce' marketplaces in some form.
