Q:What is the function of the stem nut? My valve can not be opened, is it because you want to loosen the rod nut to move?: Positioning effectPerform device link with valve stem

Q:How to set the valve stem diameter: The ball valve standard does not specify the diameter of the stem, which are required to set the careful calculation

Q:Why is the straight stroke valve stem finer?: To solve this problem, a good way is to turn the valve stem with a tour, or rotary type control valve, the valve stem stroke than the straight stem diameter of 2 ~ 3 times, and the long life of the graphite packing, valve stem stiffness, filling long life, but a small friction torque, small hysteresis.

Q:What is the standard for valve stem oiling?: Valve trapezoidal thread, the stem nut and the bracket sliding parts, gear parts part of bearing, gear and worm gear, worm and other sites with activities, are in need of better lubrication and reduce friction between each other, to avoid wear and tear each other.

Q:Is the strength of the ball valve stem and torque the same?: Depends on what the valve, but also depends on your torque is, how much pressure medium.

Q:Hydraulic manifold valve, stem movement is a positive cover, what is the role?: The spool is covered, in the middle, P mouth is closedThe manifold valves do not work together at the same time. T

Q:then stem is how to fit inside the valve body? The outside diameter of the valve stem is larger than the bore diameter: This from the valve cavity to the stem hole, you can wear in, generally like small, they are less than 15 can be worn inside.

Q:The smallest diameter of the stem refers to the diameter of the contact portion of the stem packing. The minimum stem diameter refers to the diameter of the stem slot of the valve stem: This is machining knowledge, you do sales research, this is not easy, huh, huh

Q:Why do the stem and the valve use movable connections?: 2., the valve and valve stem in one of the seals will crush the body sealing surfaceSo, of course, separate!

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.
