- Q: How is the diameter of the valve stem determined?
- In the valve manufacturing and production process standards, valve type, valve torque and valve stem diameter has a direct link.AskCan you say something about it, for example, the regulating valve?.Chasing the answerASME related standards, as well as GB GB standards relating to valve manufacturing.
- Q: DN>=50 valve, stem and bracket between the use of lubricated bearings, and stem exposed part should be dust-proof measures to prevent atmospheric corrosion. TwentyDoes it mean that all DN>=50 valves, valves and supports must be lubricated with bearings, or that only the bearings are used between the valve stem and the bearings?
- Apply a thin layer of grease can be on the exposed parts of general use, mainly to prevent locking or switch between the valve stem packing for a long time due to friction is not in place, but also to lubrication and corrosion of the
- 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: Stem material
- 1, copper alloyGenerally selected grades are QA19-2, HPb59-1-1. Applicable to the nominal pressure is less than 1.6MPa, the temperature is less than or equal to 200 degrees of low pressure valve.2 carbon steelGenerally used A5, 35 steel, after nitriding treatment, applicable to the nominal pressure of less than 2.5MPa ammonia valve, water, steam and other medium low, medium pressure valve. A5 steel is suitable for valves with temperatures not exceeding 300 degrees; steel 35 is applicable to temperatures not exceeding 450 degrees. (Note: the actual route proves that the valve stem is made of carbon steel and can not solve the corrosion problem well and should be avoided
- Q: Butterfly valve can not remove the butterfly plate, butterfly plate is fixed with pins and valve stem
- The plate is a pain in the neckMethod 1: take out the pin and go out and drill the pin out
- Q: Valve stem at the water seepage, how to repair?
- 1, the correct choice of filler;2. Do the loading according to the correct method;3, stem processing unqualified, to repair or replace;
- Q: What is the difference between them in use?
- In the soft sealing butterfly valve, no pin valve shaft, there are two main ways of connection: 1, through the shaft without pin, 2, double shaft without pin, through the shaft without pin, in the design is the most basic method, design simple. When the shaft is machined, the double half shaft has a certain degree of difficulty in making it.
- Q: The lift valve is not a single stem, but the stem and the screw are connected by the semicircle clasp. The screw rises and drives the stem to move up and down 30Want to ask why this structure instead of a whole stem, what benefits, the other is to check on the stem general calibration will stem and screw as a whole or a single check to check valve stem? Some people even say that stiffness does not need to be checked for stability
- 1., the valve and valve body hole seal, you can customize the center2., the valve and valve stem in one of the seals will crush the body sealing surface3 general sealing surface is a soft metal, or is in line with the material, stem and disc with snap ring connection good is the valve can be rotated.
- Q: Ball valve stem 90 degrees milling flat, how to process?
- two disc milling cutter in parallel with the cutter shaft, the gap is flat milling thicknessOne piece is recommended upstairs, but vertical milling is the most convenient
- Q: here's "first half week" refers to what?
- For example, fire pump, water pipe, gate valve, to see this side to the horizontal 90 degrees, turn 90 degrees in the opposite direction
