Bevel valve introduction
The Bevel valve can dissipate energy by the friction between water and air and the vortex in the water after it enters the water. When several conical valves are arranged in parallel, the distance between the axes should not be too small (for example, not less than 5 times the diameter of the valve shell D), otherwise the flow will collide with each other, resulting in a reflected flow. If the flow falls into the valve chamber, it will be difficult to operate. After improving the cone Angle of 50 °, and compared with 90 ° taper Angle valve, can make the distance between valve and valve for D (2.75 ~ 3.0), water tongue area is by two-thirds.
