Valve Applications Category Description: General condition valves General condition valves are those designed for most common operations of the valve, which has a low pressure rating in the American National Standards Institute (ANSI) 150 to 600 (diameter DN16 to DN100) with a medium rated temperature of -50 to 650 ° C (-46 to 343 ° C), corrosive media and normal pressure drop without cavitation and flashover. General condition valve design has a certain degree of interchangeability and adaptability to make them in a wide range of operating conditions. Body material is specified as carbon steel and stainless steel. Figure 1.9 shows an example of two general condition valves, one for manual valves and one for automatic valves. Special Condition Valves Special Condition Valves are custom-made valves that are designed to handle unexpected single applications of normal processes. Due to its peculiar design and manufacture, it can only be operated under parameters and operating conditions for specific operating conditions. This aspect is usually used to handle a desired temperature, altitude or in a retest medium. Figure 1.10 shows a control valve designed with a light scrape body and a ceramic cartridge to handle abrasive mineral conditions including sand particles and high pressure air. Severe condition Valves Severe condition Valves, which have special characteristics to handle volatile substances, inject high pressure drop causing serious cavitation, flash, blockage or high noise level. This kind of valve can be designed on the globe valve is very good spool. Or special disc; or special ball in the rotary valve to reduce or prevent the impact of the operation. In addition, operators or process operators require special actuators to overcome the force of the process. Figure 1.11 shows a Severe Service Valve that can handle 1,100 ° C (593 ° C) liquid Calcium with a multistage spool to handle high pressure drops with a special cooling fin on the bonnet. Electro-hydraulic actuators can generate 200000LB (889600N) thrust. This article keyword search: valve supply information
Airlock is installed below discharger under negative pressure, the outlet of upper accept discharged materials.Relying on the rotation of the impeller plays the role of conveying material, but also plays a role in sealing to prevent the pneumatic conveying air from the discharge port, to ensure the normal discharge of discharger.
