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:The role of valve stem in process gate valve
At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing.
Q:The stem is suitable for what kind of fishing
A raft is a fishing rod on a fishing raft. Now also used for freshwater fishing, fishing line can be equipped with the stroke of fish, can also be cast, can be said to be the size of the weapon system.Raft rods are usually two sections, most of which are rods, and some of them are vibrating out, but very few.
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:Heroes: how to configure the stem with buoys fishing group?
Have not tried, this one I think we should use the appropriate Handshake: Los Angeles pole
Q:Horizontal installed gate valve, stop valve stem should be in the first half of the range,
The first half of the pipeline is through the central line of the pipe and the vertical line of the central line of the pipeline above the upper half of the surface, in fact, is a circle arc (upper half arc).
Q:I would like to ask you, now the ball valve is generally designed to prevent blowing out,
The stem is put in from the middle. You can put it in a bit diagonally
Q:Can water wheel be used with valve stem?
impact and grips the guide ring and the rod body and stress surface of straight shank rod opposite a long time, easy to damage the pole.
Q:What exactly is the stem nut, please
Only in this way can the phenomenon of scuffing or rust be avoided. Stem nut materials are mainly copper alloy, steel and so on. The copper alloy is one of the main materials used for the stem nut. If Pg<1.6Mpa, the stem nut made of brass valves; if Pg16-6.4Mpa, the stem nut can be made of raw materials of Wuxi bronze; if the pressure is high, so the stem nut can be made with brass material. The material for stem nuts can also be made of steel.
Q:What is the reason for the leaking of the stem of the open rod gate valve? How to solve?
Perhaps the spool is broken, you go to the building materials market to buy a spool of the same type, you ask the merchant, they know what to give you.After returning home, turn the old spool off and change itIf you do not sell the spool alone, you buy a complete valve, back to the spool down, on the line.If it is that kind of pure plastic valve, then I'm sorry, I can only see the pipe and change the valve.
