Q:What is the cause of valve stem vibration in electric single seat control valves?: 3, liquid medium through the valve, resulting in cavitation caused by shocks, higher frequency, usually accompanied by valve howling. High temperature large pressure difference, the use of single seat valve is relatively easy to happen, this is the control valve (valve body structure) type selection caused by improper,4, the valve core resonant frequency and pipe and fluid frequency consistent with the vibration caused by higher frequency, usually accompanied by pipe vibration. Change the valve at both ends of the process, valve opening may be eliminated.

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:This summer, preparing to go on holiday to the seaside, of course, with fishing gear, I have 2.1 meters stem rod, a little hard, I would like to ask to sub bar road? I've never been cross, and if I can, what fake bait with sequins? How many grams, by the way, the fishing hook with what bait?: 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:I want to start with stem, but I don't know what brand is good, and how big wheels and main lines are used. Ask comrades to introduce. Thank you: I just got a treasure of the first sales of staff today, Shandong from Weifang, set 70 yuan, the line of what ah, all together. In 2. Still guard, eat a meal out of the box.2 1 meter 82000 wheels, wheel line 1.5, line 1, line 0.8 or 0.6 10~20, Tuo Ke. Want to use red No. 2 hook.

Q:What are their respective advantages and disadvantages?: Valve advantages:1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.5. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation

Q:The ball valve in the valve is in what state is open: Therefore, the location of the stem can not directly determine the switch status of the ball valve, such as the handle has a switch sign, you can observe the mark near the slot, at this time the valve switch with the mark.

Q:Pipeline ball valve in the valve stem generally choose what material?: Pipeline ball valve in the stem material GB1Cr13, GB1Cr18Ni9, ASTMA276-410, ASTMA276-321, and so on.Pipeline ball valve:Pipeline ball valve applies to Class150~Class1500, operating temperature of -28~300 degrees of oil, chemical, thermal power plants and other working conditions on the pipeline, cut off or switch on the media. API pipeline ball valve applicable medium: oil, purification of natural gas, acid gas, gas, water and coal slurry and so on. API pipeline ball valve drive device operating modes are: manual, worm gear drive, pneumatic, electric, gas-liquid linkage.

Q:What is the material of valve stem F6A?: 1, the ball valve F6A in the material belongs to forged low alloy or stainless steel alloy, this is the United States corresponding code.2, China this material corresponds to the model generally has two kinds, specific for 1CR13 and 2CR13.

Q:What exactly is the stem nut, please: Sometimes it is not possible to use copper alloy stem nuts for production and operation. Because some products or environment will corrode copper medium, the material of the stem nut can not be made of copper. On the basis of the electric valve, the stem nut has a melon clutch, which requires a certain amount of heat treatment to achieve more surface hardness and maximum hardness. When using the steel stem nut, we should pay attention to the thread, and the steel stem nut is easy to bite. But the stem nut is only suitable for low pressure and small bore valves. The strength of the stem nut of this material is less than that of the metal stem nut

Q:When the valve is installed, should the valve stem be lubricated, or will the material be selected?: Hello, GB/T24919-2010 "industrial valve installation, use and maintenance of general requirements," the specification of this does not require specific, general rod valve installation should be added grease. Specific depends on the implementation of instructions.

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.
