- Q: PPR ball valve which face is open, which face is closed, there is a o, there is a s, which is off, ah, which is open, well intentioned people told me that the original finished by forget
- Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.
- Q: What q25r-j159 BB-F-TE-NB represents American Standard ball?
- American Standard top mounted hard seal fixed ball valve modelQ: valve type - ball valve, BALL, VAVE2: pressure class -150cl pounds scale5: structural form - tethered body, top mounted, fixed ball (abbreviated BB-F-TE-NB)R: connection form -RF convex mesa flange connectionJ1: body material -A216-WCB cast carbon steel59: spool material -13%Cr
- Q: What does copper ball valve type Q11F-16T mean?
- 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 the nominal pressure of 10 times, T refers to the main material for copper material.
- Q: What do you mean by ball valves dn20pn1.6rf?
- DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
- Q: Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?
- Since the flow direction of the medium through the valve has changed, so the minimum flow resistance of the cut-off valve is higher than most other types of valvesThe ball valve has the lowest flow resistance
- Q: What is the ball valve core?
- The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
- Q: 3/43/8 above the ball valve is not usually said of the big ball valve?
- That is the calculation of the imperial, generally divided into two types, 1 inch (in.) 2, metric (mm) swap inch metric 1/4 (2) =6 3/8 (3) =10 1/2 (4) =12 5/8 (5) =16 3/4 (6) =18 7/8 (7) =22 1 1/8 (1 inch 1) =28,
- Q: What does 1000WOG mean on a ball screw valve?
- It's also a standard, huh?
- Q: Daily maintenance of ball valve
- Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution
- Q: DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
- 3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.
