Q:How does the positioner output change when the feedback lever of the positioner and valve stem falls off?
The positioner and the control valve are connected with the feedback rod to fall off, and the positioner has no feedback and becomes a pneumatic amplifier with high magnification. If the positioner is positive, that is, the signal increases, the output also increases, then the stem fell off, the output run the maximum, and if it is counterproductive, then run zero.
Q:Can the valve stem be sub road? Great God to help
I use sea worm, catch fish from the beach, shrimp meat and so on. Fishing play much, is keen to freshwater fishing, please answer the following.
Q:When the valve is mounted on a horizontal pipe, the ball valve stem
To the first party to do, or as requested, the handle is not down, easy to pass the acceptance. Operation is inconvenient, can add chain wheel or add operation platform.
Q:Stem V type PTFE packing maximum pressure /?
The valve packing VTa is a normal cryogenic valve with a set of V type low leakage graphite packing!Valve stem: the valve stem is not only moving parts, force components, but also seals when the valve is opened and closed.
Q:What's the fishing stem like?
The rod length should not be too long, otherwise it is not conducive to the operation in the boat, generally choose 2.1 or 2.4 meters, if fishing row seam 1.8 meters can be, as long as the toughness of the rod is enough, with a good point of the wheel can be.
Q:What is the difference between the upper valve stem bearings of the thrust bearings?
You say this is also good, but the efficiency is not high, because this method of loading is more correct, the next is the plane of the main pressure on the end surface, the upper one is axial, the main subject to the left and right. Do you think the operation of the valve is not like this?!
Q:Can the stem be fishing with sequins or something like that?
The stem is first because the ship is not suitable for long shot rod, light bait, as compared to the road sub: straight shank rod wire ring is very big, very suitable for throwing light bait, but all is not what fishing rod can not be used, it will be necessary to use a little heavier sequins, iron that weight, try to be a fine line,
Q:Is the strength of the ball valve stem and torque the same?
No, that's the two concept. In the specification, the pressure rating unchanged, including the influence factors of the medium pressure, torque, temperature, medium viscosity and so on. So the torque change. Change the stem strength structural parameters, and the change of temperature change. But the stem strength must be greater than the valve torque.
Q:The stem hook use of lead weight
Don't be conceited, brother! I am talking about the static water pond or reservoir, winter raft string hook fishing crucian carp, I fell 10 grams can play 30 meters away, 10 grams fall to taut line, completely no problem! 15 grams fall, I feel most called hand.
Q:Ball valve stem 90 degrees milling flat, how to process?
Batch processing:1 use special clamps and vertical clamps2 machine tools: horizontal milling machine3 cutter:
During more than 20 years of development, we have been specialized in manufacturing all kinds of machinery parts. professinal in finish processing ,hardware parts producing , textile usage and manned elevator machine parts ,etc.equipped with complete set machining equipment :boring mill ,miller ,punch press ,press ,engine lathe ,CNC center and gauge lathe providing a integrated services.
