What is the diameter of the 2 inch ball valve?
It depends on whether your ball valve is full diameter or necking
Calculation formula of ball valve flow
The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second. Reference: http://zhidao.baidu /question/77687541.html answer: good night dream | six | 2010-5-24 22:46It's 600 cubic meters / hour!Flow Q=600 m3 / h = 0.167m^3/sThe flow rate is V=4Q/ (3.1416D^2) = 4*0.167/ (3.1416*0.090^2) = 26.25 m/s, and the flow velocity is very large!It could be 600 cubic meters per day:Flow rate Q=600 m3 / day = 0.00694 m^3/sFlow rate V=4Q/ (3.1416D^2) = 4*0.00694/ (3.1416*0.090^2) = 1.09 m/s flow rate is normal.
Is the two piece ball valve in the direction of the pressure pipe?
First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more.
For the master enlighten Q47 ball seat spring hole number is determined by how
Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameter
Ceramic ball valve, regulating valve standard?
You can refer to the specific national standards
DN20 copper ball valve with large PPR converter connector
What do you see a ball valve, PPR ball valve, ball valve with internal screw threads, ball valves, but if you look at the butt of the ball size, if the ball is 20. The tube is 20, then the 20*1/2 internal thread can be directly on the butt.
Role of ball valve DN20-Q11F-16
Q11F ball valve is to control the circulation and cut-off of the pipeline medium.
Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?
Yes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.
