WHY THE CERAMIC LINED VALVES HAVE ANTI-ABRASIVE PERFORMANCE

Compare to the general metal valves ,ceramic valve have stepped  into the industrial field ,especially some abrasive operating conditions ,such as mining industry ,coal -fire industry ,lithium battery industry etc .
The common feature of these industries is that the medium are tough abrasive ,they easily wear out the general metal meterial .For the valves and pipes ,they have a short life time .Not only the maintenance cost are so high ,but also the system will be shut down ,those will give a bad effect to the productivity


.
How to slove this problem?  A study shows that engineer ceramic material have a high hardness and anti-abrasive peformance . At the same working situation ,ceramic 's lifte time is about 5 times of metal material . Maybe some people think ceramic is easy to break and fragile . Don't worry that question now . Some ceramic material have add flexibilizer component ,and become engineer ceramic ,not for the civil using .


As the result ,the engineer ceramic have been widely used in pipes and valves . FREE VALVE is a kind of ceramic valve brand in China ,which combined the advantage of ceramic and metal ,most of the valves are composed ceramic lined valve . The product range include ceramic lined knife gate valve ,ceramic lined double gate valve ,ceramic lined ball valve etc .To learn more information ,please visit www.free-valve.com .

How to select tank bottom valve?

图片
Tank bottom angle valves are divided into disc opening into the valve and disc opening into the tank . Sometimes ,they are also called open-down type and open-up type . The difference between the two types of tank bottom angle valve is the following : O pening into the tank type is a special kind of globe valve . When the valve opened, valve stem will move upward and disc will go the inner of tank  . However ,for the tank bottom angle valve (opening into the valve ) type ,when the valve disc rising ,valve will be opened and valve disc will be hidden into the valve body . As opening  into the tank type  ,the fluid flowing besides the inlet and outlet of the valve rate is quite high . So abrasiveness will be occurred   on the valve disc at some extent .For this structure ,the required axis distance will be little ,so it can save the space cost . For opening into the valve type ,the valve disc will hidden into valve body , ,it can protect the valve disc from ...

Application of ceramic lined ball valves in flue gas desulfurization

图片
http://www.free-valve.com 1.General Flue gas desulfurization is the main action to control the discharge of SO2 in the coal power plant . There are several desulfurization process in the international market , that is wet desulfurization ,dry desulfurization ,semi dry desulfurization and ammonia process of desulfurization. The limestone-gypsum wet flue gas desulfurization process is the most popular for high efficiency ,large capacity ,good compatibility ,reliability . Beside that , limestone work as absorber ,have a low cost and a wide availability characteristic ,its by product gypsum can be recycled after water removing . At present , the limestone-gypsum wet flue gas desulfurization process is the main process among desulfurization in the coal –fired power plant . FGD ( Flue gas desulfurization ) is a process which absorb SO2 as well as other contaminative gas by lime stone slurry in the power plant , by the same time it can produce the lime gypsum slurry by pr...

How to select ceramic lined valve type in the ash disposal system of coal power plant

图片
In the ash disposal system of coal power plant , ceramic lined valve is a important component of dry ash transporting system and pipeline system .How to make these valves works well in their position ,it is important to select right valve at for right position .   Refer to pneumatic transporting ash system ,we have to study the component of bin pump and its working theory . Bin pump is make up of feed valve ,boosting valve ,bleeder valve ,pump body and pipeline ,The control air source and conveying air source can be the same ,of course it can be set alone . The conveying pump is work to convey the coal powder , it have a high automatic equipment whose process is controlled by PLC. The system mainly include feeding equipment ,pneumatic bleeder valve ,pump ,gasification, pipelines and valves . There are four stage during the bin pump conveying process : Feeding stage : The feeding valve will be opened when the bin pump running ,the material will fall of into t...
