Liquid chlorine shut-off ball valve

by:Lianke Valve     2022-04-11
The liquid chlorine cut-off ball valve and the plug valve belong to the same kind of valve, the difference is that the ball valve uses a ball with a circular opening as the opening and closing part, and the ball rotates with the valve stem around the center line of the valve body to achieve the purpose of opening and closing the valve. The basic series of liquid chlorine cut-off ball valve is Q41F46 type, which can be divided into two types: two-piece (two-piece) type and three-piece type. The following advantages: 1. The liquid chlorine cut-off ball valve adopts a ball valve with a FEP lining layer, which has extremely high chemical stability and can be applied to any other strong corrosive properties except: 'molten alkali metal and elemental fluorine'; 2. Liquid chlorine cut-off ball valve With full-bore and floating ball structure, the valve can be closed without leakage in the entire pressure range, which is more convenient for the line sweeping of the pipeline system and pipeline maintenance; 3. The opening and closing parts of the liquid chlorine cut-off ball valve are casted (forging) as a whole, eliminating the possibility of the valve stem rushing out of the pressure-bearing parts due to pressure changes, and fundamentally ensuring the safety of use in the project; 4. The liquid chlorine cut-off ball valve has a compact and reasonable structure, and the cavity space of the valve body Minimal, reducing medium retention, in addition, the special molding process makes the sealing surface dense, and the combination of herringbone ring PTFE packing makes the valve achieve zero leakage; 5. Liquid chlorine cut-off ball valve two-piece, three-piece structure It can adapt to various pipeline systems and working conditions. The three-piece ball valve allows the main valve body to be separated from the valve bodies on both sides, which can realize rapid online replacement and maintenance. The liquid chlorine shut-off ball valve has strong corrosion resistance and is suitable for long-term transportation of acid, alkali and salt liquid media of any concentration under the temperature of -80-200 °C. It has the advantages of long service life, no aging, and no toxin decomposition. It has both the strength of carbon steel shell and the corrosion resistance of fluorine-lined material. ideal choice. Scope of application: urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection. Liquid chlorine cut-off ball valve implementation standard: design and manufacture: GB/T12237. Structure length: GB/T12221 connecting flange: JB/T78; JB/T79. Test and inspection: GB/T 13927 Applicable medium: liquid chlorine, liquid ammonia, Strong corrosive media such as various concentrations of acids, alkalis, salts, aqua regia, organic acids, etc., except for molten alkali metals and elemental fluorine. Applicable temperature: ≤150
