Valve classification method

Valve classification methods are: valve general classification, according to the pressure classification, according to the media temperature classification, according to the valve body material classification four. General taxonomy This taxonomy not only by principle, role and structure by the division, is currently the most common international and domestic classification methods. General sub-gate valves, globe valves, throttle valves, instrumentation valves, plunger valves, diaphragm valves, plug valves, ball valves, butterfly valves, check valves, pressure relief valve safety valve, Sewage valve and so on. According to the purpose and role of classification Regulating valves - mainly used to regulate the flow of media, pressure and so on. Including the control valve, throttle, pressure reducing valve. Check valve - used to prevent media backflow. Includes various configurations of check valves. Diverter valves - used to separate, distribute or mix media. Including a variety of distribution valves and traps and other structures. Safety valves - for protection against overpressure of the medium. Including various types of safety valve. Shut-off valves - Mainly used to shut off or switch on the medium flow. Including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball valve, needle valve and so on.

Optical Prisms

A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application,prism: In optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.

Dispersive prism can be used to break light up into it's constituent spectral colors(the color of the rainbow).Furthermore, prisms can be used to reflect light or to split light into components with different polarizations.

Optical Prism include Right angle prism.Equilateral dispersing prism.Dove Prism.Corner Cube Reflectors.Beamsplitter, Powell prism, dove prism, wedge prism, penta prism etc.
