- 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: What does copper ball valve type Q11F-16T mean?
- Q11F-16T, Q refers to the ball valve, 1 refers to the connection mode, the latter 1 refers to the straight through type, F refers to the sealing material, 16 refers to nominal pressure, T refers to the main material for copper material
- Q: Which is more cost-effective electric ball valve?
- All kinds of Lady valve manufacturers.The company has strong technical force, with adequate and sophisticated machining equipment as the premise, to provide a strong guarantee for the production of high-quality products,
- Q: Ask you engineer, 150mm diameter ball valve or butterfly valve, installed in the water supply pipe, water pressure 0.4Mpa, driven by the electric actuator, should much force distance?Sincere thanks, enthusiastic support of net friend.
- Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer
- 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: To help explain the meaning of the ball valve Q11H-16H, combined with the actual, such valves have wood?
- JB T308-2004 valve model preparation method and "GB1048-2005 pipe element nominal pressure definition and selection", there are various types of valve interpretation:Q11H-16HQ: valve type: (Q) ball valve1: connection form: (1) internal thread1: structure form: (1) through flow channelH: sealing surface or lining material: (H) Cr13 stainless steel16: pressure code: (16) 1.6MPaH: body material: (H) Cr13 stainless steel
- 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 are the use of all - way ball valves and reducing ball valves respectively? What are the advantages?
- Ball valves used for conveying viscous, easily slagging medium piping shall be of all sizes, allowing regular blow through of wax scraper. Used to transport gas or physical properties similar to the water medium of the pipeline should be used to reduce the diameter of the ball valve, because its weight than the full diameter of the ball valve about 30%, is conducive to reducing pipeline load and reduce costs.
- 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.
