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:Stem material
3, alloy steelGenerally choose 40Cr, 38CrMoA1A, 20CrMo1V1A and other materials. 40Cr after chrome treatment, apply to nominal pressure is less than 32MPa, temperature less than 450 degrees of water, steam, oil and other media. 38CrMoA1A after nitriding treatment, can work temperature of 540 degrees under the pressure of 10MPa, often used in power plant valve. 20CrMo1V1A after nitriding treatment, can work at 570 degrees temperature under the pressure of 14MPa, often used in power plants valve.4,Generally choose 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti and other materials. 2Cr13, 3Cr13 stainless steel for nominal pressure less than 32MPa, the temperature is less than or equal to 450 degrees of water, steam and weak corrosive medium, can be chromium plating, high frequency hardening and other methods to strengthen the surface. 1Cr17Ni2 stainless steel valves and cryogenic valves are resistant to corrosive media. 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless acid resistant steel for nominal pressure less than 6.4MPa, temperature is less than or equal to 600 degrees of high temperature valve, can also be used for temperature less than -100 degrees of stainless steel valve, low temperature valve. 1Cr18Ni9Ti can resist corrosive medium such as nitric acid; 1Cr18Ni12Mo2Ti can resist corrosive medium such as acetic acid. When 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti are used in high temperature valves, nitriding treatment can be adopted to improve the scratch resistance.
Q:Valve handwheel can move, stem does not move what is the matter?
Handwheel and stem out of line, suggest replacing new wheel
Q:What's the difference between the stem and the pole?
Well, I haven't seen the stem but I know the road and pole and other characteristics of the rod than it is a road and pole is very light very fine because the road sub Diaofa need not stop throwing in order to save energy so halleluyah pole are very light....Second, halleluyah rod is strong for waist tonality and stroke is the way fish and fish pole high sensitivity can be the first time to feel the way the bite well that I haven't seen the stem so the difference between the two can not answer you because I only play Luya road and interesting welcome to join the road sub army! Pure hand.... Hope to be of help to you!
Q:Should the valve stem be in place?
On Xue drug use is the youngest,Actually, there's a writer who loves fishing,Wrote an article on Baidu's 100 homes,Suggest you can go search below,The title of the article is: Puzzle: how old Xue medicine?We can under Baidu: Shandong Xue master
Q:Hydraulic excavator main control valve stem wear can be changed? Will the valve bore not be worn?
Hydraulic excavator is a kind of multifunctional machine, is widely used in water conservancy engineering, transportation, power engineering and mining machinery in the construction, it is to reduce the heavy manual labor, ensure the quality of the project, plays ten important role to accelerate the construction speed and improve labor productivity. Because hydraulic excavator has many varieties, multi-function, high quality and high efficiency and so on, it has been favored by the construction units. The production of hydraulic excavators is also booming.
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:Where exactly is the stem seal on top of the ice cream machine?
A single ice cream machine has only one valve plug, and the three ice cream machine has three valve plugs. The valve plug moves upward and starts the motor of the ice cream machine, which can be used to make ice cream or clean the water of the machine.
Q:Can water wheel be used with valve stem?
Temporary use, you can, for a long time, not recommended. The guide ring rods and the guide ring number, spinning line has an angle,
Q:What are the meaning of the LH for the size of the valve stem of the electric gate valve?
Valve in general, into a positive and negative thread structure, to prevent thread loosening.
