A brief introduction of ZAJQ electric ball valve.
ZAJQ electric, type O regulating ball valve is one of our company electric regulating valve series products.At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical teaching and scientific research equipment, electric power industries such as industrial automatic control system.
Second, the characteristics.
1, small fluid resistance, o-type ball valve generally have full circulation and reducing the two structures.All flow-through, in particular, the channel diameter is equal to the pipe diameter, resistance loss is equal to pipe friction resistance, in all the valves, the ball valve minimum flow resistance.In the requirements of pipeline resistance the smaller good system, ball valve is the best choice.
2, quick, convenient switch: ball valves only rotates 90 degrees from open to close, it is easy to realize rapid opening and closing.
3, sealing good: at present, most of the ball valve seat is made of elastic material such as ptfe ethylene, seal made of metal and nonmetal materials, for soft seal, easy to guarantee the sealing, and the machining accuracy and surface roughness on the surface of the sealing requirement is not high.
4, long service life: because of teflon (PTFE or F - 4) have good self-lubrication, with small sphere of friction and wear, and because the ball processing technology improvement reduces the roughness, thereby improving the service life of the ball valve.
5, high reliability: ball valve ball and seat for a pair of sealing pair, not scratches, sharp and wear failure;Stem is built-in type, eliminates the stem under the effect of fluid pressure, may be due to the packing gland to loosen and fly out of accident hidden danger.
6, the body channel level off is smooth, more suitable for conveying viscous fluid, slurry and solid particles of the medium.
