Downward-spreading glass-lined discharging valve

A glass lined discharge valve overview:
Under the expansion of glass lined discharge valve The equipment is high in silicon content of the vitreous enamel. By about 9000C high temperature coating metal and tire. It has good mechanical properties and corrosion resistance, can prevent the media and the metal ion to replace the impact of contaminated products, and smooth surface, wear a certain thermal stability. Widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries.
The valve structure figure, suitable for P design pressure is less than or equal to 0.6MPa, the expansion of the discharge valve working temperature T = 1500C glass lined up. The valve shall comply with the provisions of HG5-16-79 technical conditions. This valve phosphorus and phosphorus light medium, hydrofluorocarbons, hydrochloric acid, sodium hydroxide and potassium hydroxide outside the competence of various acid, alkali and salt solution and organic solvents.
Two, Under the expansion of glass lined discharge valve The performance of the main equipment:
(a) corrosion resistance
1, the general ability of inorganic and organic acids of weak alkali (P less than or equal to 60 DEG PH = 12) and organic medium;
In 2, hydrochloric acid, nitric acid, water and other strong corrosive medium is better than stainless steel;
3, prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature higher than 150 DEG C concentration > 30%);
(two) to allow the use of heat resistance at -30 DEG to +240 DEG C (between the high temperature blast is less than 120 degrees C);
(three) has a smooth surface. Difficult to bond materials, easy to clean;
(four): glass insulation material has good insulation, 1mm thick glass in high voltage of 2000 volts will not breakdown conduction;
(five) impact resistance: less impact resistance of 2500 g / cm, and thus should avoid use of the impact of hard objects;
(six) pressure: 0.6Mpa.
Three, Under the expansion of glass lined discharge valve Performance specification:

Four, dimensions:

Five, glass lined discharge valve maintenance and installation notes:
1, in the decoration of all places must contact with the porcelain surface with asbestos or PTFE films such as cushion. The use of tools and porcelain surface impact or friction, but can not use metal tools to shovel.
Tighten the fastening screws on the 2, when surrounded by other forces, to prevent the porcelain surface uneven force and crack of porcelain. Discharge valve screw to keep lubrication, prevent rust.
3, through the medium is liquid, no hard particles into a liquid, prevent porcelain suede or jam, and open failure etc..
4, departments should pay attention to the installation of the screw force is balanced, lifting (activities) is flexible.
5, in the face of the enamel seal should maintain the center position. Uniform pressure, to prevent leakage.
6, if the use of leakage, should immediately check the sealing device is appropriatein and can not be used iron rods, rod fastening handwheel hard, so as not to damage the parts.
7, when the material blocked, you can use the metal bar or rigid tool to clear, do not use metal bar or rigid tool.
8, should try to avoid acid-base media used interchangeably (except in and reaction medium), so as not to shorten life.
9, according to media performance and the use of PTFE sheet, should often check valve neck of PTFE seals and orifice plate part. If there are damaged should be replaced before use.
10, if it is found that the porcelain surface is damaged should be immediately suspended. Available special paint repair the affected area, or entrust the relevant units to do the production of enamel.
