Valve body type selection

There are many types of regulating valve body, commonly used through a single seat, through two-seater, angular, diaphragm, small flow, tee, eccentric rotation, butterfly, sleeve, spherical and so on. In the specific choice, the following considerations can be made: (1) The shape of the valve spool is mainly based on the selected flow characteristics and unbalanced forces and other factors to consider. (2) Abrasion resistance When the fluid medium is a suspension containing high concentration of abrasive particles, the internal material of the valve should be rigid. (3) Corrosion Due to the media corrosive, try to choose a simple structure of the valve. (4) Medium temperature, pressure When the medium temperature, high pressure and changes, should use the valve core and valve seat material by temperature, pressure changes in small valves. (5) to prevent flash and cavitation flash and cavitation only produce liquid medium. In the actual production process, flash and cavitation will form vibration and noise, shorten the life of the valve, so the valve should be selected to prevent flash and cavitation.

Wear Resistant Ceramic Alumina Ball are a class of alumina balls that are referred to as high alumina balls due to their high alumina content. The high Alumina Ball can be subdivided into series of 90, 92, 95, 99 according to the alumina content. High aluminum ball is widely used in different types of ceramics, enamel, glass, chemical industry because of its high strength, high hardness, high wear resistance, excellent specific gravity, small volume, high temperature resistance, corrosion resistance and pollution-free. And so on the factory's thick and hard materials finishing and deep processing. Taking the high-aluminum ball of 92 content as an example, the specific gravity (density) should reach 3.60 or more, the alumina content should be above 91.5, and the iron content is low. The same raw material, the same formulation, and the same baking temperature, the smaller the fineness of the powder after the raw material is ground, the higher the specific gravity and the better the wear resistance.
