Q:Halleluyah fishing method with the stem line?
Or choose the special road pole better, "work to good things, must first benefit its device" well!
Q:DN>=50 valves use grease lubricated bearings between the stem and the support
When the utility model is used, a thin layer of grease is applied on the exposed part of the valve stem, so that lubrication can not only be played in operation, but also can prevent the exposed part of corrosion.
Q:What is the function of the stem nut?
Positioning effectPerform device link with valve stem
Q:River fishing rod or sea pole?
Sea rods are good stem valve rod head to buy hard to buy sea pole soft lead is generally 50 to 150 ha, I also listen to them.
Q:Stem deformation of valve stem
So why would the stem fracture or deformation of a few points: normal temperature and pressure of the valve body cavity there is closed, that is closed in the valve, the fluid pressure in the cavity closed at the upstream and downstream sides between the sealing surface is far higher than the upstream pressure.
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:What are the connecting ways of valve plate and valve stem of gate valve?
Valve faults:Between the sealing surface is easy to cause erosion and scratches, maintenance is more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
Q:What are the specialized equipment for producing valve stem?
CNC CNC lathe, CNC milling machine, CNC milling machine is now the fastest can be in place. This part of Wenzhou is called a flying (milling) stem,Gate valve, globe valve and other T thread are CNC milling machine flying, professional processing valve stem is doing so
Q:How to judge the quality of fishing stem?!
The regular brand fishing line, mellow, soft texture, good surface smoothness, high strength, good wear resistance nodules. At present, the market of various brands of fishing, whether mixed together.
Q:When the valve is mounted on a horizontal pipe, the ball valve stem
The ball valve and butterfly valve stem can be level downward, the installation angle is unrestricted. Globe valves are mounted horizontally or vertically.
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.
