Q: How can a steel ball in a steel ball valve be put in?: This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.

Q: Can the ball valves be used in heating?: Ball valve because of its geometry and the sealing of the pipeline is relatively good, so many applications. The heating is fine, of course.

Q: You can connect inside the pump and valve: Pump and valve should be installed between the distance, too close, too far, will cause damage to the ball valve. The flange is usually used on the pump. Valve can be connected with a pipe with screw pipe, a head welding flange, and the flange is directly connected with the water pump. Super - Electronic Commerce

Q: Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?: The seal on the valve body is broken. Screw it down and change the gasket

Q: What is the diameter of the 2 inch ball valve?: It depends on whether your ball valve is full diameter or necking

Q: One stainless steel ball, two pieces, three pieces of difference, use: A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.

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: What is the ball valve Q11F -16 material?: If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg

Q: Where can I buy this Y filter with a ball valve?: This valve is added after the filter, directly on the flange welding joints or holes in the flange is connected with a ball valve tapping, can double wire, because the Y type filter is standard, relatively good buy, relatively less modification

Q: 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.
