- Q: Is the ball valve installed in a direction?
- Valve installation generally no direction required, any end of the valve can be mounted on the upper end. If the valve marked the direction, then it should be installed in the direction of tagging installed.
- Q: Role of ball valve DN20-Q11F-16
- Type Q - 1 - connection form: threaded connection1 - gate structure: single gateF: PTFE sealing materialsDN - nominal diameter mm 2016 pressure rating: 161.6MPaQ11F ball valve is to control the circulation and cut-off of the pipeline medium.
- Q: What does "DN25 Q41F46-16C" mean?
- DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of general diameter of 25 mm
- Q: Ball valve 11F, 41F, 11H, 41H
- 41F flanged ball valve type sealed through using tetrafluoroethylene; 11H is threaded through valve type the alloy steel seal;
- Q: What are the inside parts of the ball valve?
- The universal ball valve includes the stem, valve ball, seat, seat seal and packing.
- Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?
- When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body
- Q: What's the difference between air valves, butterfly valves and ball valves?
- On the pipeline, mainly from cutting and throttling.Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.Ball valve: opening and closing parts (sphere) driven by the stem, and around the square ball valve for the axis of the rotating valve.Shanghai Guardian valve, all types of valves are industry-leading.
- Q: Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!
- This is a manual ball valve three simple when meet your requirements is L ball 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: What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
- In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.
