Low, pressure loss very little saves energy, is a kind of environmentally friendly product.
The common structure of ball valve is divided into float ball valve and Fixed ball valve.Float ball valve is generally used for small-bore, low
Pressure difference;Fixed ball valve is generally used for larger caliber, High Pressure Difference.As new device scale is increasing, parameter is higher and higher,
Fixing ball valve have developed rapidly.The keying torque of fixing ball valve is small, be heavy caliber, high pressure operating mode main force's structure type.Fixed ball
Valve has been popularized in gas, liquid medium operating mode use, quite ripe, but contains a large amount of solid-states in such as coal chemical industry, polysilicon etc.
The operating mode of grain then uses not satisfactory.
In the contour solid operating mode of coal chemical industry, due to the presence of particle, there are pivots to kill and preloading spring card for fixing ball valve
Dead two kinds of typical failure patterns.Ball valve will rotate in opening process, and when part is opened, lumen is directly connected to runner, largely
Solid granulates enter lumen and deposit, and pivot can be caused to kill.If medium also contains easy coking component, valve can be caused faster
Forfeiture operational capacity.Hard seal ball valve needs spring to establish initially than pressure, when the particle in medium is in the gradual heap in spring rear portion
Product, can make spring loss of function, lead to valves leakage.
Currently used solution is to use floating ball valve, but the operational torque of heavy caliber high pressure floating ball valve is big, warp
Ji property is bad.Preloading spring position has plenty of using safeguard measure, prevents medium from entering, but due to the presence of pressure, effect
It is not fine;There is a method in which being exactly to accommodate spring, but the rising of manufacturing cost can be caused using larger space.
