Top Ten Brands of Coal Water Slurry Pneumatic Dust Ball Valve The butterfly valve is normally 90 ° from fully open to fully closed? The butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it can be quickly opened and closed only by rotating 90 °, which is simple to operate? The opening and closing parts of the gate valve are the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed?,? Adjustment and throttling are not allowed. The gate has two sealing surfaces. The advantages of the gate valve are: small fluid resistance, less effort in opening and closing, unrestricted medium flow direction, no flow disturbance and no pressure reduction
What is the important basis for the performance of pneumatic butterfly valve?
As the technology of pneumatic butterfly valve matures and develops from time to time, its ways can be described as various. How do people judge the performance of pneumatic butterfly valve in daily life?
At present, most of the wire mesh sleeves consumed are 24 strand, 36 strand, 48 strand, 64 strand, extra large diameter bellows, and 96 strand, 120 strand and 144 strand. In addition to the number of strands (wire), wire diameter, number of spindles (strip) and thickness, the main knitting parameters of the mesh cover also include cover area, knitting distance, knitting angle, etc.
Ordinary pneumatic butterfly valve only uses one layer of mesh sleeve; In special application places, there are also woven two-layer and three-layer corrugated pipes, which are usually made of wire with a diameter of 0.3~0.8mm or tape with a thickness of 0.2~0.5mm according to the size of the corrugated pipe diameter and application requirements. There are 4-15 wires per share and one strip per ingot. Usually, when people choose pneumatic butterfly valves, they mainly depend on the size of the mesh to determine the performance of the mesh. Therefore, in conclusion, the important basis for determining the performance of pneumatic butterfly valve is the net sleeve.
