ceramic Industrial Valves selection and maintenance in the selection, mainly according to the different media, choose different types of ceramic lining.

。 For acid, alkali, the highest use temperature does not exceed 90 ℃, can choose acid-resistant ceramic lining.

b。 For acid, alkali, require resistance to temperature leaps at the same time, the highest use temperature does not exceed 150 ℃, can choose acid-resistant and heat-resistant ceramic lining.

C。 For acid, alkali, the highest temperature less than 150 c, can choose hard ceramic lining.

d。 For hydrofluoric acid resistant, can choose calcium fluoride porcelain lining.

e。 For acid, alkali, when the highest use temperature over 150 ℃, and require leaps and resistance to temperature stress is larger, can choose mullite ceramics, 75% alumina ceramic or 97% alumina ceramic. Alumina content is higher, the better performance, but make the big valve parts is difficult, the cost is much higher.

in the process of storage transportation, ceramic Industrial Valves installation, should pay attention to the following

a. The characteristics of the ceramic is very brittle, fragile, for a typical brittle material, so is the generality of the storage and transportation, light moving light put, it is forbidden to collision and throw and prevent package materil box.

b。 Best indoor storage, unconditional and stacked in outdoor, should choose a flat, solid, not water area, the bottom of the pile should be underlay, and waterproof measures, during the winter should pay attention to waterproof, antifreeze, prevent ceramic split after repeated freezing and thawing.

C。 Can be used according to the product shape order PingMa or place fold way pallet, and according to the specifications, and piled, stacking is unfavorable and exorbitant, outdoor stack should be glazed down, in case of rain and snow accumulation, prevent mildew is yellow.

d。 Custody period normally not more than two years, and master the principle of first in first out.

e。 Transportation requirements: must be packed in wooden cases or foamed plastics, and foaming plastic box, plug the gap in the basket. The car stacking is unfavorable and exorbitant, and the edges and bulge and filled the gap between parts and the parts, fill with hemp rope tied after the car. It is strictly prohibited in the cast throw to prevent the crushing of the product.

f。 In the installation and operation, should be especially careful, not too hard, too hard or impact.
