Q:Can aluminum alloy 6061 be used as stem?
The main alloying elements in Alloy 6061 pan Shanghai bamboo provides for magnesium and silicon, with medium strength, good corrosion resistance, weldability and oxidation effect. Widely used in various industrial structure requires a certain strength and high corrosion resistance of antibiotics, such as the manufacture of the truck, tower building, ship, car, railway vehicles, furniture and so on.
Q:What's the difference between the stem and the pole?
Raft pole...... Sit with the kind of fishing in the boat, and the road sub Diaofa like; not the same, halleluyah fishing method to search online for yourself
Q:What is the dish yellow in the valve?
What's the valve? You should say "butterfly spring". If it is, it will fix some parts
Q:The valve core and the valve stem must be screwed,
The matching of the valve core and the valve stem can only guarantee the maximum degree of concentricity by using the transition fit. Considering the need for loading and unloading, so I have the front, I said, only the use of higher precision gap fit".
Q:What is the appearance of the valve with no stem valve?
Limiting valve: in the fluid system "valve"Define the flow direction of the flow by means of pressure control. The pipe and valve are a medium (liquid, gas, powder) that stops flowing within the device and can control the flow of the device. According to the open and close valve
Q:Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?
3Cr13 martensitic stainless steel, C content is relatively high, if the S is dry, corrosion resistance is relatively small, with 3Cr13 not what big problem, if the water is single, cannot use 3Cr13,
Q:What are the connecting ways of valve plate and valve stem of gate valve?
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:Are there any problems with the horizontal installation of the pneumatic butterfly valve on the horizontal pipe? Is it serious?
Especially the butterfly valve pneumatic valve is generally installed vertically, horizontally mounted, the stem sealing effect of internal gravity packing layer, resulting in loose packing, the risk of leakage, and the pneumatic valve of the valve positioner will reduce the accuracy of adjusting clearance, cause.In addition, the butterfly valve sealing surface may also be deformed because of the stem deformation and wear.This is the danger, not necessarily be a problem, but the large-diameter valves such as DN150 or more dangerous, if you have a small caliber valve (butterfly valves are generally large, with a small caliber ball valve), will do some suggestions, safety, adjust the installation position.
Q:Is the strength of the ball valve stem and torque the same?
No, that's the two concept. In the specification, the pressure rating unchanged, including the influence factors of the medium pressure, torque, temperature, medium viscosity and so on. So the torque change. Change the stem strength structural parameters, and the change of temperature change. But the stem strength must be greater than the valve torque.
Q:Horizontal installed gate valve, stop valve stem should be in the first half of the range,
It is better to be within 45 degrees of the vertical direction.
