Liquid chlorine cut-off ball valve implementation of standards (Figure)
Liquid chlorine cut off the ball valve implementation of the standard liquid chlorine cut-off valve and the plug valve is the same type of valve, the difference is that the ball valve is used with circular ball also open and close the ball, the ball with the valve stem around the center line to achieve the valve The purpose of account opening and closing. The basic series of liquid chlorine cut-off ball valve is Q41F46, which can be divided into two types (two pieces) and three pieces. In addition to the general fluid valve with a small ball valve resistance, fast opening and closing, simple structure, there are The following advantages: 1, liquid chlorine cut-off ball valve with FEP lining ball valve, with high chemical stability, can be applied except: "molten alkali metal and elemental fluorine," any other than the strong corrosion properties; 2, liquid chlorine cut ball valve Full-diameter, floating ball structure, the valve can be leak-free closure throughout the pressure range, more convenient line system of the line sweeping and pipeline maintenance; 3, liquid chlorine cut ball valve opening and closing pieces of the ball and stem casting (Forging) as a whole, to eliminate the possibility of stem stem out of the pressure due to pressure changes, fundamentally ensure the safety of the project; 4, liquid chlorine cut ball valve structure is compact and reasonable, the body cavity space Minimum, reducing the media retention, in addition, a special molding process, the sealing surface density is good, combined with herringbone annular PTFE packing combination, the valve to zero leakage; 5, liquid chlorine cut off Valve two-piece, three-piece construction for the various piping systems and working conditions of the different requirements, wherein three sides of the ball valve allows the main valve body and the separation line can be achieved quickly replaced, maintenance. Liquid chlorine cut off valve has a very strong corrosion resistance, suitable for -80-200 ℃ temperature conditions, long-term delivery of any concentration of acid, alkali, salt liquid medium. Long life, no aging, no toxin decomposition, etc., both the strength of the carbon steel casing, and lined with fluorine material corrosion resistance, petroleum, chemical, rubber, plastics, pharmaceuticals, paper making, electroplating, smelting and many other industries Ideal for Scope of application: urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection.
