- Q: How much pressure DN65 ball valve?
- 16-40 is normal pressure. How much pressure do you want?
- Q: Valve and ball valve is the same thing? Don't know don't speak
- Ball valve is only a kind of valve, is very common, the middle of the spool is spherical.Many types of valves, in addition to ball valves, there are common gate valve, stop valve, butterfly valve, check valve and so on.
- Q: Is the ball valve switch in front of the water meter or after the water meter?
- the owners of their own decoration or repair, in front of the water meter is generally C type locking valve or valve, if less water, property control, no special key you open
- Q: Check valve, ball valve, check valve are used in what place, ah?
- The cut-off valve is generally used in the inlet pipe, the outlet valve is generally used in the official website, convenient switch, check valve is to allow water to flow past the water directed, anti back, generally used in vertical pipe, the equivalent of the pump valve
- Q: 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.
- Q: Is the two piece ball valve in the direction of the pressure pipe?
- Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
- Q: What's the meaning of the ball valve bore 14 "x 12"?
- Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.
- Q: Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?
- Ordinary ball valve is the reverse turn off, the general ball valve without direction requirements. Each kind has the direction request, generally has the arrow or the nameplate explanation on the valve body.
- Q: Water heater ball valve is not very easy to pull, why does it feel bad?
- Use the hair dryer, hot air gear to blow for a while, slowly screw, a bit loose, continue to screw, you can completely screw, and more than a few twists and turns, long time does not move, it will be stuck
