The Selection And Transportation of Ceramic Valves

Selection and maintenance of ceramic valve In the selection, mainly according to different media, the selection of different types of ceramic lining.

• Acid and alkali resistance is required. When the maximum use temperature does not exceed 90 ° C, acid-resistant ceramics can be used as the lining.

• Require acid and alkali resistance, while requiring rapid temperature change, the maximum use temperature does not exceed 150 ° C, acid and temperature resistant ceramics can be used as the lining.

• Acid and alkali resistance, the maximum use temperature does not exceed 150C, hard ceramic can be used as the lining.

• Require resistance to hydrofluoric acid, calcium fluoride porcelain can be used as the lining.

• require acid and alkali resistance, when the maximum use temperature exceeds 150 ° C, but also require rapid temperature change and large force, mullite ceramics, 75% alumina ceramics or 97% alumina ceramics can be used. The higher the alumina content, the better the performance, but the manufacture of large valve parts is more difficult and the cost is much higher.

In the storage and transportation, ceramic valve installation process, should pay attention to the following

• Ceramic is characterized by brittleness and fragility, which is a typical brittle material, so the commonality of storage and transportation is that it is carried lightly, and it is strictly prohibited to crash and throw, and prevent loose bags and boxes.
  

• The best indoor storage, unconditional and stacked outdoors, must choose a flat, solid, no water site, the bottom of the pile should be padded, and there are anti-rain measures, pay attention to waterproof and anti-freeze in winter, to prevent ceramic cracking after repeated freezing and thawing.
  

• According to the shape of the product can be used sequential flat code or slot stacking stacking, and according to the variety, specifications, respectively stacked, stacking should not be too high, outdoor stacking should be glazed down, to prevent rain and snow accumulation, to prevent mildew yellow.
  

• The storage period is generally not more than two years, and master the principle of first-in-first-out.
  

• Transportation requirements: The transportation must be packed in wooden boxes or foamed plastics, and the gaps in the boxes and baskets should be packed tightly with foamed plastics. The stacking on the car should not be too high, and fill the gap between the corners and the convex part and the pieces, and tie the car with twine after filling the car. It is strictly forbidden to throw during handling to prevent the product from breaking.
  

• During installation and operation, special care should be taken not to exert too much force, excessive force or impact.
